Infants in some areas of China developed urinary lithiasis after being fed with powdered milk that was tainted with melamine in 2008 and very small proportion of the infants developed acute renal failure caused by urinary tract calculus obstruction. The aim of this article was to summarize clinical characteristics, diagnosis and treatment of infants with urinary calculus and acute renal failure developed after being fed with melamine tainted formula milk. Data of infant patients with urinary calculus and acute renal failure due to melamine tainted formula milk admitted to the Beijing Children's Hospital Affiliated to the Capital Medical University and the Xuzhou Children's Hospital in 2008 were used to analyze the epidemiological characteristics, clinical manifestations, imaging features as well as effects of 4 types of therapies. All the 34 infants with urinary calculus were complicated with acute renal failure, their blood urea nitrogen (BUN) was (24.1+/-8.2) mmol/L and creatinine (Cr) was (384.2+/-201.2) micromol/L. The chemical analysis on the urinary calculus sampled from 15 of the infants showed that the calculus contained melamine and acidum uricum. The time needed for the four types of therapies for returning Cr to normal was (3.5+/-1.9) days for cystoscopy group, (2.7+/-1.1) days for lithotomy group, (3.8+/-2.3) days for dialysis group, and (2.7+/-1.6) days for medical treatment group, which had no statistically significant difference (P=0.508). Renal failure of all the 34 infants was relieved within 1 to 7 days, averaging (3.00+/-1.78) days. Melamine tainted formula milk may cause urinary calculus and obstructive acute renal failure. It is suggested that firstly the patients with urinary calculus complicated with acute renal failure should be treated with dialysis or medication to correct electrolyte disturbance, in particular hyperkalemia, and then relieve the obstruction with available medical and surgical methods as soon as possible. It was observed that the short-term prognosis was satisfactory.

Urinary retention and syndrome of inappropriate antidiuretic hormone secretion (SIADH) secondary to impacted gravid uterus.

Irani, M; Fisher, N; Mor, A; Bensinger, G

Urinary retention is an emergency that rarely occurs during pregnancy. Previous case reports have suggested multiple risk factors that can cause the gravid uterus to become impacted in the pelvis leading to lower bladder or urethral compression with subsequent urinary retention. However, no cases of urinary obstruction in a pregnancy that was complicated with severe electrolyte imbalance have been reported. To our knowledge, we report the first case of a 31-year-old woman presenting at 8 weeks' gestation with acute urinary retention caused by a retroflexed, retroverted uterus with a 6-cm posterior uterine fibroid leading to syndrome of inappropriate antidiuretic hormone secretion and severe hyponatremia requiring intensive care unit admission. The cornerstones of effective management of urinary retention should include: (i) urgent bladder catheterization; (ii) assessment of sodium levels to rule out syndrome of inappropriate antidiuretic hormone secretion, and prompt treatment before neurological damage occurs; (iii) reduction of the impacted uterus; and (iv) monitoring for post-obstructive diuresis. © 2016 Japan Society of Obstetrics and Gynecology.

Infectious complications remain a major cause of morbidity and mortality among transplant recipients. Urinary tract infection (UTI) is the most common infectious complication in kidney transplant recipients with a reported incidence from 25% to 75%, varies widely likely due to differences in definition, diagnostic criteria, study design, and length of observation. We sought reviews the incidence and importance of urinary tract infection on graft survival, the microbiology with special emphasis on multidrug resistant microorganisms, the therapeutic management of UTI and the prophylaxis of recurrent UTI among solid organ transplant recipients, highlighting the need for prospective clinical trials to unify the clinical management in this population.

Tamarelle, B; Perrin, P; Devonec, M; Paparel, P; Ruffion, A

To identify hospitalizations directly related to a complication occurring within 30 days following a transrectal prostate biopsy (PBP). Overall hospitalization rates, mortality rates, potential predisposing factors for complications. Single-center study including all patients who underwent PBP between January 2005 and January 2012. Any hospitalization occurring within 30 days of the PBP for urgent motive was considered potentially attributable to biopsy. We identified the reason for hospitalization with direct complications (urinary infection or fever, rectal bleeding, bladder caillotage, retention) and indirect (underlying comorbidities decompensation) of the biopsy. The contributing factors were anticoagulant or antiplatelet treatment well as waning immunity factors (corticosteroid therapy, HIV, chemotherapy or immunodulateur). Among 2715 men who underwent PBP, there were 120 (4.4%) hospitalizations including 28 (1.03%) caused by the biopsy. Twenty-five (0.92%) were related to a direct complication of biopsy: 14 (56%) for urinary tract infection or fever including 1 hospitalization in intensive care, 5 (20%) for rectal bleeding which required several transfusions 1, 10 (40%) urinary retention and 3 (0.11%) for an indirect complication (2 coronary syndromes and 1 respiratory failure). Several direct complications were associated in 3 cases. Only two hospitalizations associated with rectal bleeding were taking an antiplatelet or anticoagulant. There was no association between hospitalization for urinary tract infections and a decreased immune status. The first death observed in our study occurred at D31 of pulmonary embolism (advanced metastatic patient with bladder cancer). Twenty (60.6%) patients urgently hospitalized did not have prostate cancer. Within this large sample of patients the overall rate of hospitalization due to the realization of a PBP was 1%. It has not been found predictive of complications leading to hospitalization. 4. Copyright © 2016. Published by Elsevier Masson SAS.

Complicated catheter-associated urinary tract infections due to Escherichia coli and Proteus mirabilis.

2008-01-01

Catheter-associated urinary tract infections (CAUTIs) represent the most common type of nosocomial infection and are a major health concern due to the complications and frequent recurrence. These infections are often caused by Escherichia coli and Proteus mirabilis. Gram-negative bacterial species that cause CAUTIs express a number of virulence factors associated with adhesion, motility, biofilm formation, immunoavoidance, and nutrient acquisition as well as factors that cause damage to the host. These infections can be reduced by limiting catheter usage and ensuring that health care professionals correctly use closed-system Foley catheters. A number of novel approaches such as condom and suprapubic catheters, intermittent catheterization, new surfaces, catheters with antimicrobial agents, and probiotics have thus far met with limited success. While the diagnosis of symptomatic versus asymptomatic CAUTIs may be a contentious issue, it is generally agreed that once a catheterized patient is believed to have a symptomatic urinary tract infection, the catheter is removed if possible due to the high rate of relapse. Research focusing on the pathogenesis of CAUTIs will lead to a better understanding of the disease process and will subsequently lead to the development of new diagnosis, prevention, and treatment options.

Synergism between amoxicillin and clavulanic acid was not expected against cephalosporinase-producing bacterial strains because clavulanic acid has little inhibitory action on cephalosporinases. However, in a clinical trial of BRL 25000 (amoxicillin-clavulanic acid), excellent results were obtained in complicated urinary tract infections caused by Serratia marcescens, Enterobacter cloacae, and Citrobacter freundii strains which produced cephalosporinase and were highly resistant to amoxicillin alone. The good clinical efficacy of BRL 25000 in such urinary tract infections was probably due to the fact that the urinary concentration of clavulanic acid was higher than its minimal inhibitory concentrations for these strains.

2012-03-01

This ICI-RS report aims to analyze morphological or functional complications of the lower or upper urinary tract in elderly men, clarify the association between complications and benign prostatic obstruction (BPO) and define men who will develop these complications. Research proposals to further enlighten these associations were to be defined. A think-tank discussion was held on the annual ICI-RS meeting in 2011. The published literature between 1966 and 2011 was reviewed and research proposals were defined with all congress participants. Post-void residual, bladder diverticula or calculi, vesico-ureteral reflux, hydronephrosis, renal insufficiency, and urinary retention appear with greater prevalence in patients with symptoms or signs of benign prostatic hyperplasia. BPO may directly or indirectly be responsible for these complications but conclusive evidence for BPO as the primary cause does not exist. Many of the complications have a multifactorial etiology and BPO is only partially responsible. It is currently impossible to define men who will develop complications. In contrast to the widespread belief of urologist, there is only rudimentary data available showing no convincing association between urinary tract complications and BPO. The ICI-RS proposes that prospective trials are conducted to demonstrate the association between complications and BPO by using cystometry, pressure-flow (P/F) studies, and other commonly used BPO parameters in men with complications and comparing those with a cohort of age-matched men without complications. Non-invasive proxy parameters of BPO, for example, ultrasonic measurement of detrusor wall thickness, can be used instead of P/F studies especially in longitudinal trials.

Acosta, Eduardo Mariano Albers; Reyes, Alfonsi Friera; Menéndez, Ricardo Brime

2015-01-01

The ectopic varices in patients with portal hypertension are those that occur at any level of the gastrointestinal (GI) tract, regardless of the varices that occur at the esophageal level. These ectopic varices account for 2–5% of the causes of GI bleeding varices. The risk of bleeding is quadrupled compared to the esophagogastric area, with a mortality of up to 40%. The transjugular intrahepatic portosystemic shunt, should be considered in cases secondary to recurrent bleeding varices. We present a case report of an urological emergency of bleeding in a urinary diversion secondary to ectopic varices successfully treated through the placement of transjugular intrahepatic portosystemic shunt. The condition described here is rare, but important, as it can be a life-threatening complication of portal hypertension. This kind of complication should be known by urologic surgeons managing patients with urinary diversions. PMID:26834901

ABSTRACT Vesicovaginal fistula is an abnormal communication between the bladder and vagina and represents the most frequent type of fistula in the urinary tract. The most common cause in Brazil is iatrogenic fistula, secondary to histerectomia. Classically these women present continuous urinary leakage from the vagina and absence of micturition, with strong negative impact on their quality of life. We present a case of totally continent vesicovaginal fistula, with a follow-up of 11 years with no complications. PMID:23579756

Iatrogenic injury to the urinary tract, including the kidneys, ureters, bladder, and urethra, is a potential complication of surgical procedures performed in or around the retroperitoneal abdominal space or pelvis. While both diagnostic and interventional radiologists often play a central and decisive role in the identification and initial management of a variety of iatrogenic injuries, discussions of these injuries are often directed toward specialists such as urologists, obstetricians, gynecologists, and general surgeons whose procedures are most often implicated in iatrogenic urinary tract injuries. Interventional radiologic procedures can also be a source of an iatrogenic urinary tract injury. This review describes the clinical presentation, risk factors, imaging findings, and management of iatrogenic renal vascular and urinary tract injuries, as well as the radiologist's role in the diagnosis, treatment, and cause of these injuries.

Microbial diversity in biofilm infections of the urinary tract with the use of sonication techniques.

PubMed

Holá, Veronika; Ruzicka, Filip; Horka, Marie

2010-08-01

Infections of the urinary tract account for >40% of nosocomial infections; most of these are infections in catheterized patients. Bacterial colonization of the urinary tract and catheters causes not only the particular infection but also a number of complications, for example blockage of catheters with crystallic deposits of bacterial origin, generation of gravels and pyelonephritis. Infections of urinary catheters are only rarely single-species infections. The longer a patient is catheterized, the higher the diversity of biofilm microbial communities. The aims of this study were to investigate the microbial diversity on the catheters and to compare the ability to form biofilm among isolated microbial species. The next aim was to discriminate particular causative agents of infections of the urinary tract and their importance as biofilm formers in the microbial community on the urinary catheter. We examined catheters from 535 patients and isolated 1555 strains of microorganisms. Most of the catheters were infected by three or more microorganisms; only 12.5% showed monomicrobial infection. Among the microorganisms isolated from the urinary catheters, there were significant differences in biofilm-forming ability, and we therefore conclude that some microbial species have greater potential to cause a biofilm-based infection, whereas others can be only passive members of the biofilm community.

Urinary tract infection is the most common infectious complication following renal transplantation and its frequency is insufficiently studied in Portugal. The aim of this study was to characterize the incidence of urinary tract infections and recurrent urinary tract infections in renal transplant recipients. This was a retrospective cohort observational study, obtained from clinical files of all patients who received a renal transplant at the Hospital of Santa Cruz, from January 2004 to December 2005, with a mean follow-up period of five years or until date of graft loss, death or loss of follow-up. After a descriptive analysis of the population, we used bivariate tests to identify risk factors for urinary tract infections. A total of 127 patients were included, with a 593 patients.year follow-up. We detected 53 patients (41.7%) presenting with at least one episode of urinary tract infection; 21 patients (16.5%) had recurrent urinary tract infection. Female gender was the only risk factor associated with the occurrence of urinary tract infections (p < 0.001, OR = 7.08, RR = 2.95) and recurrent urinary tract infections (p < 0.001, OR = 4.66, RR = 2.83). Escherichia coli (51.6%), Klebsiella pneumoniae (15.5%) and Enterobacter spp (9.9%) were the most frequently identified pathogens. Patients did not reveal an increased mortality or allograft loss. However, urinary tract infections were the most important cause of hospital admissions. Female gender was the only risk factor for urinary tract infections in this population. Escherichia coli was the most frequent agent isolated. Despite preventive measures, urinary tract infections remain an important cause of morbidity and hospital admissions.

Nephrogenic diabetes insipidus (NDI) is characterized by the kidney's inability to concentrate urine, which causes intense polyuria that may lead to urinary tract dilation. We report the morphological findings of the urinary tract in ten boys with NDI specifically addressing the presence and changes of urinary tract dilation during treatment. Patients were diagnosed at a median age of 1.6 years (range, 0.16-6.33 years) and treated with a low osmotic diet, hydrochlorothiazide-amiloride and indomethacin, which decreased the diuresis from a median of 10.5 ml/kg/h to 4.4 ml/kg/h (p < 0.001). Three patients showed normal renal ultrasound before treatment until last control, while the remaining seven showed urinary tract dilation. In this second group, dilation was reduced with treatment in four patients and disappeared in the remaining three. Children without dilation or in whom the dilation disappeared were diagnosed and treated earlier than those with persistent dilation (median 1.66 versus 4.45 years, respectively). After a median of 10.4 (range, 2.3-20.3) years of follow-up, no patients showed urological complications. Medical treatment of the disease improved the dilation in all cases, preventing its potential complications. Regardless of the good outcome of our patients, periodic urologic follow-up is recommended in NDI patients.

Concurrent urinary tract infection and stone disease: pathogenesis, diagnosis and management.

PubMed

Thomas, Ben; Tolley, David

2008-12-01

Urinary tract stones and urinary tract infection are strongly associated. Infection is implicated as the cause of stones in about 15% of stone formers, and the development of infection can complicate the management of pre-existing stones. Left untreated, both situations can result in loss of kidney function, and can, on occasion, be life threatening. The underlying pathophysiology of infection stones is generally well understood, but factors dictating why a particular individual should be affected are less clear, although obstruction is a uniformly recognized risk factor. Surgery is the mainstay of treatment for infection calculi: stone clearance is the goal and a range of minimally invasive treatments is available. Systemic sepsis remains the most serious complication of treatment, and, although rare, still occurs despite antibiotic prophylaxis. Once the stone and the causative infection have been removed, various strategies can be employed to minimize the risk of recurrence. When infection complicates pre-existing stone disease, the primary aim of management is to treat the infective episode and delay definitive stone management until the infection has cleared. In such cases where obstruction is also present, prompt drainage of the affected kidney is likely to prevent permanent renal damage, and may be life saving.

Urinary tract infections, asymptomatic bacteriuria (AB), acute cystitis (AC) and acute pyelonephritis (AP), are favored by the morphological and functional changes involved in pregnancy. AB increases the risk of preterm labor, low birth weight and AP. AB should be detected by uroculture (other methods are not sufficiently effective) and treated early. Approximately 80% of cases are caused by Escherichia coli. The risks and effectiveness of the distinct antibiotic regimens should be evaluated: fosfomycin trometamol in monotherapy or as short course therapy is safe and effective for the treatment of AB and AC. AP is the most frequent cause of hospital admission for medical reasons in pregnant women and can lead to complications in 10% of cases, putting the lives of the mother and fetus at risk. Currently outpatient treatment of AP is recommended in selected cases. Adequate follow-up of pregnant women with urinary tract infections is required due to frequent recurrence.

Recurrent Urinary Tract Infections Management in Women

2013-01-01

Urinary tract infections (UTIs) are one of the most frequent clinical bacterial infections in women, accounting for nearly 25% of all infections. Around 50–60% of women will develop UTIs in their lifetimes. Escherichia coli is the organism that causes UTIs in most patients. Recurrent UTIs (RUTI) are mainly caused by reinfection by the same pathogen. Having frequent sexual intercourse is one of the greatest risk factors for RUTIs. In a subgroup of individuals with coexisting morbid conditions, complicated RUTIs can lead to upper tract infections or urosepsis. Although the initial treatment is antimicrobial therapy, use of different prophylactic regimens and alternative strategies are available to reduce exposure to antibiotics. PMID:23984019

Uterine leiomyomas are common gynecologic tumor in reproductive-aged women, by age 50, diagnosis shared by urologist, gynecologists and radiologists. The goal of this article is to review the current literature, study the impact of leiomyoma on female lower urinary tract, examine the cause female sexual dysfunction and provide a comprehensive review of current diagnostic, imaging studies, and current treatment of leiomyoma. Clinical leiomyoma studies published from 1956 through 2015 were identified using the PubMed search engines and the key words leiomyoma, fibroid in the current literature. Impact of leiomyoma on the lower urinary tract including female sexual dysfunction was reviewed with terms of "urinary retention", "bladder", "urethra", "dyspareunia", "incontinence", "incomplete bladder emptying", "female sexual dysfunction", and "lower urinary tract" to study the urological and sexual effects of leiomyoma. Literature related to leiomyoma was reviewed from 1965 to present. Women with uterine leiomyomata complained of pelvic pain, menstrual irregularities, infertility, lower urinary tract symptoms and sexual dysfunction. Leiomyoma is a common tumor of the uterus that often clinically impacts on the lower urinary tract and results in urological and sexual symptoms. Leiomyoma can compress and grow into and become adherent to the bladder and surrounding pelvic organs or metastasize into peritoneal organs. Leiomyoma can enlarge and compress the urinary bladder, urethra, and lower end of the ureters. Leiomyoma can cause embarrassing sexual dysfunction in females. Current literature of non-surgical and surgical therapy of leiomyoma is described.

Urinary tract infection is certainly one of the most common childhood infections. Emerging resistance to the antibiotics is not unusual. Current hospitalization for children with urinary tract infection is reserved for severe or complicated cases. The aim of the present study was to determine the antibiotic resistance pattern among children with recurrent or complicated urinary tract infection. A retrospective study carried out at Prince Hashem hospital, Zarqa city, eastern Jordan and involved 336 episodes of culture proved urinary tract infection obtained from 121 patients with recurrent UTI, who used prophylactic antibiotics during the period from April 1, 2004 to December 31, 2006. The isolated microorganisms and there antibiotics susceptibility were studied. Seventy three patients (60.3%) were found to have some forms of urinary tract anomaly, significantly more prevalent among male children P<0.001. Vesicoureteral reflux being the most common (58.9%). Renal scars were significantly more prevalent among those with complicated rather than recurrent urinary tract infection (64.3% vs. 16.6%, P<0.001). Gram negative organisms were the most frequent isolates in patients with recurrent and complicated urinary tract infection. Proteus, Pseudomonas and Candida spp. were more prevalent in patients with complicated (P<0.001), and isolates in patients with UTA were significantly more resistant to most antibiotics tested. Pediatric urine culture isolates are becoming increasingly resistant to commonly used antibiotics. Empirical treatment with Trimethoprim-Sulfamethoxazole (TMP-SMX) or Cephalexin as the initial drug is ineffective. Nitrofurantoin and Nalidixic acid can be considered as the first line antibiotics for prophylaxis and or treatment of patients with recurrent UTI, while Meropenam and Ciprofloxacin can be used empirically in treating patients with complicated UTI.

To evaluate the occurrence of severe urinary complications within 2 years of surgery in men undergoing either robot-assisted radical prostatectomy (RARP), laparoscopic radical prostatectomy (LRP) or retropubic open radical prostatectomy (ORP). We conducted a population-based cohort study in men who underwent RARP (n = 4 947), LRP (n = 5 479) or ORP (n = 6 873) between 2008 and 2012 in the English National Health Service (NHS) using national cancer registry records linked to Hospital Episodes Statistics, an administrative database of admissions to NHS hospitals. We identified the occurrence of any severe urinary or severe stricture-related complication within 2 years of surgery using a validated tool. Multi-level regression modelling was used to determine the association between the type of surgery and occurrence of complications, with adjustment for patient and surgical factors. Men undergoing RARP were least likely to experience any urinary complication (10.5%) or a stricture-related complication (3.3%) compared with those who had LRP (15.8% any or 5.7% stricture-related) or ORP (19.1% any or 6.9% stricture-related). The impact of the type of surgery on the occurrence of any urinary or stricture-related complications remained statistically significant after adjustment for patient and surgical factors (P < 0.01). Men who underwent RARP had the lowest risk of developing severe urinary complications within 2 years of surgery. © 2017 The Authors BJU International published by John Wiley & Sons Ltd on behalf of BJU International.

The present study investigated the incidence of hyperammonemia in urinary tract infections and explored the utility of urinary obstruction relief and antimicrobial administration to improve hyperammonemia. This was an observational study. Subjects were patients who were diagnosed with urinary tract infection and hospitalized between June 2008 and June 2009. We measured plasma ammonia levels on admission in patients who were clinically diagnosed with urinary tract infection and hospitalized. We assessed each patient's level of consciousness on admission using the Glasgow Coma Scale (GCS) and performed urine and blood cultures. We also assessed hearing prior to hospitalization using the Eastern Cooperative Oncology Group performance status (ECOG-PS). In cases with high ammonia levels on admission, plasma ammonia and GCS were measured 24 hours and 5-7 days later. Sixty-seven candidates were enrolled; of these, 60 cases (89.6%) with bacterial cell counts ≥10(4) CFU/mL were studied. Five cases (8.3%) presented with high plasma ammonia levels. Cases with hyperammonemia were significantly more likely to present with low GCS scores and urinary retention rate. All five cases received antimicrobial therapy with an indwelling bladder catheter to relieve urinary retention. The case 5 patient died shortly after admission due to complicated aspiration pneumonia; in the remaining cases, plasma ammonia levels were rapidly normalized and the level of consciousness improved. The occurrence of hyperammonemia in urinary tract infections is not rare. The cause of hyperammonemia is urinary retention obstruction. Therefore, along with antimicrobial administration, relief of obstruction is important for the treatment of hyperammonemia caused by this mechanism.

Legionella pneumonia is occasionally accompanied by renal complications; however, the cause of this remains unknown. We herein report a 70-year-old Japanese man with Legionella pneumonia who presented with hyponatremia, hypophosphatemia, and hypouricemia. The levels of urinary β2-microglobulin and N-acetyl-β-D-glucosaminidase were remarkably high, indicating severe renal tubular damage. The presence of glycosuria and aminoaciduria as well as increased fractional excretion of uric acid and decreased tubular reabsorption of phosphate indicated that the patient's condition was complicated with Fanconi syndrome. After antimicrobial therapy, the electrolyte abnormalities and renal tubular damage were completely resolved.

Fungus balls have been rarely implicated as a cause of urinary tract obstruction. Here, we report a case of Candida albicans fungus balls in the urinary tract after the treatment of Candida endophthalmitis that has enough periods and adequate amount of antifungal agents. The patient completely recovered from this rare complication by irrigating through single-J stent and changing antifungal agents. Here we emphasize that we should take into account not only the susceptibility test results but also the difference in excretion route and tissue distribution of antifungal agents.

Complete staghorn calculus in polycystic kidney disease: infection is still the cause

PubMed Central

2013-01-01

Background Kidney stones in patients with autosomal dominant polycystic kidney disease are common, regarded as the consequence of the combination of anatomic abnormality and metabolic risk factors. However, complete staghorn calculus is rare in polycystic kidney disease and predicts a gloomy prognosis of kidney. For general population, recent data showed metabolic factors were the dominant causes for staghorn calculus, but for polycystic kidney disease patients, the cause for staghorn calculus remained elusive. Case presentation We report a case of complete staghorm calculus in a polycystic kidney disease patient induced by repeatedly urinary tract infections. This 37-year-old autosomal dominant polycystic kidney disease female with positive family history was admitted in this hospital for repeatedly upper urinary tract infection for 3 years. CT scan revealed the existence of a complete staghorn calculus in her right kidney, while there was no kidney stone 3 years before, and the urinary stone component analysis showed the composition of calculus was magnesium ammonium phosphate. Conclusion UTI is an important complication for polycystic kidney disease and will facilitate the formation of staghorn calculi. As staghorn calculi are associated with kidney fibrosis and high long-term renal deterioration rate, prompt control of urinary tract infection in polycystic kidney disease patient will be beneficial in preventing staghorn calculus formation.

Speakman, Mark J; Cheng, Xi

2014-04-01

Most men will develop histological BPH if they live long enough. Approximately, half will develop benign prostatic enlargement (BPE) and about half of these will get BOO with high bladder pressures and low flow, this in turn leads to detrusor wall hypertrophy. Many of these men will only have lower urinary tract symptoms (LUTS) but a significant number will also suffer the other complications of BPH. These include urinary retention (acute and chronic), haematuria, urinary tract infection, bladder stones, bladder wall damage, renal dysfunction, incontinence and erectile dysfunction. Recognition of the complications of BPH/BOO early allows more effective management of these complications. This is particularly important for the more serious urinary infections and also for high-pressure chronic retention (HPCR). Complications of LUTS/BPH are very rare in clinical trials because of their strict inclusion and exclusion criteria but are more common in real life practice.

To summarize clinical characteristics, diagnosis and treatment of infants with urinary calculus and acute renal failure developed after being fed with melamine tainted formula milk. Data of infant patients with urinary calculus and acute renal failure due to melamine tainted formula milk admitted to the Beijing Children's Hospital affiliated to the Capital Medical University and the Xuzhou Children's Hospital in 2008 were used to analyze the epidemiological characteristics, clinical manifestations, image features as well as effects of 4 types of therapies. All the 34 infants with urinary calculus were complicated with acute renal failure, their blood urea nitrogen (BUN) was (24.1 +/- 8.2) mmol/L and creatinine (Cr) was (384.2 +/- 201.2) micromol/L. The chemical analysis on the urinary calculus sampled from 14 of the infants showed that the calculus contained melamine and acidum uricum. The time needed for the four types of therapies for returning Cr to normal was (3.5 +/- 1.9) d for cystoscopy group, (2.7 +/- 1.1) d for lithotomy group, (3.8 +/- 2.3) d for dialysis group, and (2.7 +/- 1.6) d for medical treatment group, which had no statistically significant difference (P = 0.508). Renal failure of all the 34 infants was relieved within 1 to 7 days, averaging (3.0 +/- 1.8) d. Melamine tainted formula milk may cause urinary calculus and obstructive acute renal failure. It is suggested that firstly the patients with urinary calculus complicated with acute renal failure should be treated with dialysis or medication to correct electrolyte disturbances, in particular hyperkalemia, and then relieve the obstruction with available medical and surgical methods as soon as possible. It is observed that the short term prognosis is satisfactory.

We report the operative and early postoperative complications and limitations in 133 patients treated with the holmium laser. Complications included urinary tract infection (N = 3), postoperative bradycardia (1), inverted T-waves (1), intractable flank pain (1), urinary retention (1), inability to access a lower-pole calix with a 365-microm fiber (9), stone migration (5), and termination of procedure because of poor visibility (2). No ureteral perforations or strictures occurred, and no complications were directly attributable to the laser. The holmium laser was capable of fragmenting all urinary calculi in this study. In our initial experience, the holmium laser is safe and effective in the treatment of urinary pathology. Use of laser fibers larger than 200 microm occasionally limits deflection of the endoscope into a lower-pole or dependent calix.

The contribution of Pseudomonas aeruginosa virulence factors and host factors in the establishment of urinary tract infections.

Pseudomonas aeruginosa can cause complicated urinary tract infections, particularly in people with catheters, which can lead to pyelonephritis. Whilst some subgroups appear more susceptible to infection, such as the elderly and women, the contribution of other host factors and bacterial virulence factors to successful infection remains relatively understudied. In this review, we explore the potential role of P. aeruginosa virulence factors including phenazines, quorum sensing, biofilm formation and siderophores along with host factors such as Tamm-Horsfall protein, osmotic stress and iron specifically on establishment of successful infection in the urinary niche. P. aeruginosa urinary tract infections are highly antibiotic resistant and require costly and intensive treatment. By understanding the infection dynamics of this organism within this specific niche, we may be able to identify novel therapeutic strategies to enhance the use of existing antibiotics. © FEMS 2017.

Urinary tract infections (UTI) are the most common bacterial infections involving lower (cystitis, prostatitis) or upper (pyelonephritis, renal abscess, perinephric abscess) urinary tract. Differentiation of complicated and uncomplicated UTI is usually based on the presence of structural or functional urinary tract abnormalities, which can increase the risk of treatment failure and development of serious complications. Factors that increase the risk are foreign bodies, stones, obstruction, neurogenic bladder, kidney transplantation, immunosuppression, and pregnancy. Complicated UTI includes a spectrum of conditions that increase the risk of treatment failure, as well as of serious complications such as bacteremia and sepsis, perinephric abscess, renal impairment and emphysematous pyelonephritis. To avoid the potentially devastating outcomes, appropriate diagnostic procedures, antibiotic and surgical treatment, and appropriate follow-up are required. The incidence of complicated UTI will grow in the future due to general aging of the population, increasing incidence of diabetes, and ever growing number of immunocompromised and immunosuppressed patients. It is of key importance to recognize complicated UTI on time, and treat it wisely and aggressively to reduce duration of the disease and the risk of antibiotic resistance.

Complexities of management of a urostomy in Ehlers-Danlos syndrome: a reflective account.

PubMed

Oxenham, Julie

Mary (pseudonym) is a 30-year-old woman who underwent a urinary diversion and formation of an ileal conduit/urostomy (urinary stoma) due to the formation of multiple bladder diverticula, which caused micturition difficulties and recurrent urinary tract infections with associated pain and discomfort. The bladder diverticula were caused by Ehlers-Danlos syndrome (EDS), a hereditary disorder of the connective tissue or, particulary, defective collagen. Surgical intervention in patients with EDS is prone to complications due to poor wound healing, including issues of dehiscence, postoperative bleeding and poor uptake of anaesthesia and analgesia. After an initial presentation of the syndrome of EDS and Mary's history, this article offers a reflective account (informed by Gibbs' Reflective Cycle) and illustrates the complexities of caring for an individual with EDS who undergoes stoma formation. The author, a stoma care nurse, demonstrates how using purposeful reflection resulted in better understanding and awareness of caring for an individual with a rare syndrome and the nursing challenges this presented.

Fluoroquinolones are a guideline-recommended therapy for complicated urinary tract infections, including pyelonephritis. Elevated drug concentrations of fluoroquinolones in the urine and therapy with high-dose levofloxacin are believed to overcome resistance and effectively treat infections caused by resistant bacteria. The ASPECT-cUTI phase 3 clinical trial (ClinicalTrials.gov, NCT01345929 and NCT01345955 , both registered April 28, 2011) provided an opportunity to test this hypothesis by examining the clinical and microbiological outcomes of high-dose levofloxacin treatment by levofloxacin minimum inhibitory concentration. Patients were randomly assigned 1:1 to ceftolozane/tazobactam (1.5 g intravenous every 8 h) or levofloxacin (750 mg intravenous once daily) for 7 days of therapy. The ASPECT-cUTI study provided data on 370 patients with at least one isolate of Enterobacteriaceae at baseline who were treated with levofloxacin. Outcomes were assessed at the test-of-cure (5-9 days after treatment) and late follow-up (21-42 days after treatment) visits in the microbiologically evaluable population (N = 327). Test-of-cure clinical cure rates above 90% were observed at minimum inhibitory concentrations ≤4 μg/mL. Microbiological eradication rates were consistently >90% at levofloxacin minimum inhibitory concentrations ≤0.06 μg/mL. Lack of eradication of causative pathogens at the test-of-cure visit increased the likelihood of relapse by the late follow-up visit. Results from this study do not support levofloxacin therapy for complicated urinary tract infections caused by organisms with levofloxacin minimum inhibitory concentrations ≥4 μg/mL.

Male stress urinary incontinence (SUI) can significantly diminish quality of life and lead to embarrassment and social withdrawal. Surgical therapies, such as male urethral slings and artificial urinary sphincters (AUS), are considered effective and safe treatments for male SUI. Our objective is to evaluate 30-day complications in patients undergoing male slings and AUS placement from a national multicenter database. Data from the American College of Surgeons National Surgical Quality of Improvement Program for 2008-2013 were used to identify patients who underwent male slings and AUS implantation. Trained coders abstracted complication data from the patient record independent of the surgical team. We compared 30-day postoperative complications for male slings and AUS. We examined the relationship between patient factors and complication rates for each procedure type. Overall, 1205 incontinence surgeries in men were identified: 597 male sling placements and 608 AUS implantations. Male sling placement had a lower 30-day postoperative complication rate compared to AUS (2.8 vs. 5.1 %, p = 0.046). Compared to AUS, male sling was associated with fewer urinary tract infections (0.3 vs. 2.0 %, p = 0.020) and return trips to the operating room (1.0 vs. 3.0 %, p < 0.001). Patients with higher BMI were more likely to have a complication, while age, race and Charlson comorbidity index were not associated with higher or lower complication rates. Complications rates for both male sling and AUS are low. Male sling is associated with a lower rate of complications than AUS. These findings allow for better patient perioperative counseling regarding 30-day perioperative complications.

Selectivity is the most emphasized advantage of photodynamic therapy (PDT). However, at drug and light doses used for clinical applications, response from normal tissue surrounding the tumor reduces the real selectivity of the drug-light system and increases the surface of the area responding to the treatment. It is now evident that light irradiation of a sensitized patient produces damage at a various degree not only in the tumor but also in non-neoplastic tissues included in the field of irradiation. We report our experience in endoscopic PDT of early stage tumors in tracheobronchial, gastrointestinal and urinary tracts, describing early and late local complications caused by the damage of normal tissues adjacent to the tumors and included in the field of light irradiation. Among 44 patients treated, local complications, attributable to a poor selectivity of the modality, occurred in 6 patients (14%). In particular, the rate of local complications was 9% in patients treated for esophageal tumors, 14% in patients with gastric tumors, 9% in patients with tracheobronchial tumors, and 67% in bladder cancer patients. Clinical pictures as well as endoscopic findings at various intervals from treatment showed that mucositis is a common event following endoscopic PDT. It causes exudation and significant tissue inflammatory response, whose consequences are different in the various organs treated. Photoradiation must be, as much as possible, limited to the malignant area.

In order to study the pathogenesis, clinical and pathological characteristics of proliferative lesions of the bladder, 50 cases of proliferative lesions of the bladder from 150 patients with complaints of frequency, urgency, hematuria and dysuria were subjected to cystoscopic biopsy of the suspicious foci in the bladder. In combination with the symptoms, urine and urodynamics, the relationship of proliferative lesions of the bladder to the inflammation and obstruction of the lower urinary tract was analyzed. Of the 50 cases of proliferative bladder lesions, 44 cases (88%) had lower urinary tract infection and 29 (58%) lower urinary tract obstruction. The patients with lower urinary tract obstruction were all complicated with infection. Three cases were associated with transitional cell carcinoma. Malignant cells were detected in 1 case by urinary cytologic examination. Proliferative lesions of the bladder, especially those without other obvious mucosa changes under cystoscopy, are common histological variants of urothelium in the patients with chronic inflammation and obstruction of the lower urinary tract. Chronic inflammation and obstruction of the lower urinary tract might be the causes for proliferative lesions of the bladder. It is suggested that different treatments should be applied according to the scope and histological type of the proliferative lesions.

A retrospective study of 81 patients with dementia in a long-term care facility was conducted to determine the causes and frequency of acute hospitalization and the cause of death in the patients who succumbed during the acute hospital admission. Pneumonia and urinary tract infections were the most frequent causes of acute hospitalization; septicemia and respiratory failure were the most frequent causes of death. These results suggest that patients with dementia are prone to acquire life-threatening infections. Preventive measures to decrease the incidence of these complications are discussed. PMID:2500533

To analyze the feasibility and perioperative results of patients undergoing robot-assisted cystectomy with intracorporeal urinary diversion and robot-sewn ileoileal anastomosis. This is a mono-centric analysis of perioperative data from 48 consecutive patients undergoing robot-assisted cystectomy with intracorporeal urinary diversion and robot-sewn ileoileal anastomosis. Data include the preoperative variables, operative and postoperative course and complication rates related to bowel anastomosis. End points were time spent for anastomosis and intra- and postoperative complication rates. Median operating time was 23.0 (13-60) min for the ileoileal anastomosis. Median overall operating time was 295 (200-780) min, with a median of 282 (200-418) min and 414.0 (225-780) min for the ileum conduit (N = 35) and ileal neobladder (N = 13). Two patients developed paralytic ileus; in another patient acute peritonitis occurred, but was caused by urinary leakage and therefore unrelated to the bowel anastomosis. No anastomotic leakage was noticed. Costs for the robot-sewn anastomosis was 8€ compared to 1250€ for a stapled anastomosis which was performed in previous cases. Limitations are the non-comparative nature of the analysis and the limited number of patients. Robot-sewn ileoileal anastomosis is feasible with low complication rates. Compared to the stapled anastomosis, a robot-sewn ileoileal anastomosis may serve as an alternative and cost-saving approach.

Urinary tract infection in children is well recognized as a cause of acute morbidity and chronic medical conditions. As a result, appropriate use of antimicrobial agents, however, increases antibiotic resistance and complicates its treatment due to increased patient morbidity, costs, rates of hospitalization, and use of broader-spectrum antibiotics. The goal of this study was to determine antibiotic susceptibility to commonly used agents for urinary tract infection against recent urinary isolates. A total of 457 consecutive children attending the emergency room at the Hospital Infantil de México Federico Gómez with symptoms of uncomplicated lower urinary tract infection were eligible for inclusion. Patients who had had symptoms for≥7 days and those who had had previous episodes of urinary tract infection, received antibiotics or other complicated factors were excluded. Midstream and catheter urine specimens were collected. All isolates were identified and the in vitro activities of antimicrobials were determined. The most frequently isolated urinary pathogens were as follows: Escherichia coli (E. coli) (312, 68.3%), Enterococcus spp. (42, 11%), Klebsiella pneumoniae (K. pneumoniae) (40, 8.7%), Pseudomonas aeruginosa (P. aeruginosa) (34, 7.5%), Proteus mirabilis (P. mirabilis) (21, 4.5%), Enterobacter cloacae (8, 1.7%). The resistance to trimetoprim/sulfametoxazol (%) was 73.7, 62.2, 100, 52, and 50, respectively, for E. coli, K. pneumoniae, P. aeruginosa, P. mirabilis and Enterobacter spp., 92.5 for Enterococcus faecalis (E. faecalis) and 49.9 for Enterococcus faecium (E. faecium). Ampicillin was 86.3, 45, 100, 47.9, and 66.6% for the same strains, ciprofloxacin 33.8, 9, 18.8, 0, 0%, nitrofurantoin 4.4, 13, 97.7, 70, 0%; to E. faecalis 0% and 16.7% to E. faecium. Frequently prescribed empirical agents for uncomplicated urinary tract infection demonstrate lowered in vitro susceptibilities when tested against recent clinical isolates.

Retrospective database review. Posterior/posterolateral lumbar fusion (PLF) is an effective treatment for a variety of spinal disorders; however, variations in surgical technique have different complication profiles. The aim of our study was to quantify the frequency of various complications in patients undergoing PLF with and without human recombinant bone morphogenetic protein 2 (rhBMP2). We queried the orthopedic subset of the Medicare database (PearlDiver) between 2005 and 2011 for patients undergoing PLF procedures with and without rhBMP2. Complication and reoperation rates were analyzed within 1 year of the index procedure. Complications assessed include: acute renal failure, deep vein thrombosis, dural tear, hematoma, heterotopic ossification, incision and drainage, cardiac complications, nervous system complications, osteolysis, pneumonia, pseudarthrosis, pulmonary embolism, radiculopathy, respiratory complications, sepsis, urinary retention, urinary tract infection, mechanical, and wound complications. Chi-square analysis was used to calculate the complication differences between the groups. Our data revealed higher overall complication rates in patients undergoing PLF with rhBMP2 versus no_rhBMP2 (76.9% vs 68.8%, P < .05). Stratified by gender, rhBMP2 males had higher rates of mechanical complications, pseudarthrosis, and reoperations compared with no_rhBMP2 males ( P < .05), whereas rhBMP2 females had higher rates of pseudarthrosis, urinary tract infection, and urinary retention compared with no_rhBMP2 females ( P < .05). Our data revealed higher overall complication rates in PLF patients given rhBMP2 compared with no_rhBMP2. Furthermore, our data suggests that rhBMP2-associated complications may be gender specific.

Urodynamic evaluation is frequently used in the follow-up of the treatment and diagnosis of incontinence, which develops in connection with a neurogenic or non-neurogenic reason. There is no identified serious complication during or after urodynamic evaluation, present in the literature up to date. Hematuria, due to the urethral catheter, the development of oedema in the urinary bladder wall and the development of urinary bladder spasm as a result of catheter irritation, are some of the complications, which may occur. In this paper, twist and knot formation in the double lumen urethral catheter after cystometry of a patient with a hypocompliant urinary bladder, has been presented.

Toxicity testing of urinary catheters.

The tissue toxicity of 23 urinary catheter batches (6 latex and 2 non-latex brands) was tested in vitro and in vivo. In vitro, a human T-cell leukemia line (JM) was cultured in the presence of different concentrations of eluates made from the catheters. The cytotoxicity of the eluates was assessed from their ability to inhibit DNA synthesis measured by incorporation of 3H-thymidine. In vivo, two methods were used. Strips of catheters were implanted into the rabbit dorsal muscle and pieces of catheters were implanted into the rat peritoneal cavity. After four days, the foreign body reaction, type of inflammation and necrosis were quantified macroscopically and by light microscopy. The results of the in vitro cytotoxicity test were correlated with those of in vivo methods. The rat peritoneal implantation test correlated better with the cell culture test (P less than 0.01) than with the rabbit muscle implantation test (P less than 0.05). Based on the clinical experience of urethral stricture complications caused by urinary catheters, catheters yielding eluate which at 30% dilution inhibited 50% DNA synthesis were regarded as toxic. According to this, the rabbit muscle implantation test was not reliable in testing the tissue toxicity of urinary catheters, while the cell culture test was quantitative and seemed to correlate with both the rat peritoneal implantation test and with the clinical complications observed.

Large sliding inguino-scrotal hernia of the urinary bladder

Abstract Rationale: Sliding inguinal hernias of the urinary bladder are protrusions of the bladder through the internal inguinal ring, most of which are insignificant and diagnosed intra-operatively. Large inguino-scrotal bladder hernias commonly present with lower urinary tract symptoms and may cause severe complications, including bladder incarceration or necrosis, bladder hemorrhage, obstructive or neurogenic bladder dysfunction, and even renal failure. Patient concerns: We describe and discuss the clinical findings and management of a 59-year-old man who complained of a decrease in scrotal size after voiding and 2-stage voiding requiring pressure to the scrotum. Diagnoses: The patient was diagnosed preoperatively as massive, bilateral, inguinoscrotal hernias, and a large, left-sided, sliding bladder hernia. Interventions: The patient underwent a timely open re-peritoneal inguinal herniorrhaphy using a mesh. Outcomes: The surgical outcomes were good, and no surgical site infection, chronic postoperative inguinal pain or recurrence were recorded during the follow-up. Lessons: Better knowledge of this rare condition of large inguino-scrotal sliding bladder hernia could help in making a correct diagnosis preoperatively and provide proper surgical management timely, so as to reduce delay in treatment and avoid potential complications.

Urinary tract infections (UTI) are among the most common bacterial infections in humans, affecting millions of people every year. UTI cause significant morbidity in women throughout their lifespan, in infant boys, in older men, in individuals with underlying urinary tract abnormalities, and in those that require long-term urethral catheterization, such as patients with spinal cord injuries or incapacitated individuals living in nursing homes. Serious sequelae include frequent recurrences, pyelonephritis with sepsis, renal damage in young children, pre-term birth, and complications of frequent antimicrobial use including high-level antibiotic resistance and Clostridium difficile colitis. Uropathogenic E. coli (UPEC) cause the vast majority of UTI, but less common pathogens such as Enterococcus faecalis and other enterococci frequently take advantage of an abnormal or catheterized urinary tract to cause opportunistic infections. While antibiotic therapy has historically been very successful in controlling UTI, the high rate of recurrence remains a major problem, and many individuals suffer from chronically recurring UTI, requiring long-term prophylactic antibiotic regimens to prevent recurrent UTI. Furthermore, the global emergence of multi-drug resistant UPEC in the past ten years spotlights the need for alternative therapeutic and preventative strategies to combat UTI, including anti-infective drug therapies and vaccines. In this chapter, we review recent advances in the field of UTI pathogenesis, with an emphasis on the identification of promising drug and vaccine targets. We then discuss the development of new UTI drugs and vaccines, highlighting the challenges these approaches face and the need for a greater understanding of urinary tract mucosal immunity.

Complicated urinary tract infections, such as pyelonephritis, may lead to sepsis. Rapid diagnosis is needed to identify the causative urinary pathogen and to verify the appropriate empirical antimicrobial therapy. We describe here a rapid identification method for urinary pathogens: urine is incubated on chocolate agar for 3h at 35°C with 5% CO2 and subjected to MALDI-TOF MS analysis by VITEK MS. Overall 207 screened clinical urine samples were tested in parallel with conventional urine culture. The method, called U-si-MALDI-TOF (urine short incubation MALDI-TOF), showed correct identification for 86% of Gram-negative urinary tract pathogens (Escherichia coli, Klebsiella pneumoniae, and other Enterobacteriaceae), when present at >10(5)cfu/ml in culture (n=107), compared with conventional culture method. However, Gram-positive bacteria (n=28) were not successfully identified by U-si-MALDI-TOF. This method is especially suitable for rapid identification of E. coli, the most common cause of urinary tract infections and urosepsis. Turnaround time for identification using U-si-MALDI-TOF compared with conventional urine culture was improved from 24h to 4-6h. Copyright © 2016 Elsevier B.V. All rights reserved.

Breakthrough urinary tract infections (BUTIs) are a source of great morbidity in children on urinary prophylactic antibiotics. The incidence of BUTI in critically ill infants is not known. We investigated the incidence of BUTI in a cohort of infants hospitalized on prophylactic antibiotics in neonatal intensive care units. Predictors of BUTI were evaluated using multivariable Cox regression. Out of 716,787 infants, 631 (0.09%) were prescribed 821 courses of antibiotic prophylaxis. Among this cohort, 60 infants (9.5%) suffered a total of 65 BUTIs. Of all prophylactic antibiotic courses, 65/821 (7.9%) were complicated by BUTI. Klebsiella, Enterobacter, and Escherichia coli species were the most common causes of BUTI. There was no statistically significant difference in BUTI incidence among the four antibiotics assessed (amoxicillin, cephalexin, nitrofurantoin, or trimethoprim-sulfamethoxazole) (p=0.78).

Inappropriate use of indwelling urinary catheters (IUCs) and their related complications is one of the most important problems in hospital wards. The aim of this study was to evaluate inappropriate use of IUCs and their complications among patients in Tehran, Iran. Two hundred and six consecutive patients hospitalized in the intensive care unit (ICU) as well as medical and surgical wards at the Shahid Mohammadi Hospital in Bandarabbas from September 1 to 30, 2005 and in whom IUCs were used, were studied. Data collected included age of the patients, diagnoses, reason for use of IUC and the complications related to it. Overall, 164 patients (79.6%) had IUCs used appropriately while 42 of them (20.6%) were catheterized unjustifiably. Inappropriate use of IUCs in the ICU, medical and surgical wards was reported in 12 (18.5%), 16 (19.0%) and 14 patients (24.6%), respectively. The most common complication of IUCs was urinary tract infection, which occurred in 91 patients (44.2%) and hematuria, which was seen in 3.9% of the patients. Our study suggests that inappropriate use of IUCs is prevalent, particularly in the surgical wards, and the most common complication observed was catheter-associated urinary tract infection.

To study the impact of glycaemic control on urinary incontinence in women who participated in the Diabetes Control and Complications Trial (DCCT; 1983-1993) and its observational follow-up study, the Epidemiology of Diabetes Interventions and Complications (EDIC; 1994-present). Study participants were women who completed, at both years 10 (2003) and 17 (2010) of the EDIC follow-up, the urological assessment questionnaire (UroEDIC). Urinary incontinence was defined as self-reported involuntary leakage of urine that occurred at least weekly. Incident urinary incontinence was defined as weekly urinary incontinence present at EDIC year 17 but not at EDIC year 10. Multivariable regression models were used to examine the association of incident urinary incontinence with comorbid prevalent conditions and glycaemic control (mean HbA 1c over the first 10 years of EDIC). A total of 64 (15.3%) women with Type 1 diabetes (mean age 43.6 ± 6.3 years at EDIC year 10) reported incident urinary incontinence at EDIC year 17. When adjusted for clinical covariates (including age, DCCT cohort assignment, DCCT treatment arm, BMI, insulin dosage, parity, hysterectomy, autonomic neuropathy and urinary tract infection in the last year), the mean EDIC HbA 1c was associated with increased odds of incident urinary incontinence (odds ratio 1.03, 95% CI 1.01-1.06 per mmol/mol increase; odds ratio 1.41, 95% CI 1.07-1.89 per % HbA 1c increase). Incident urinary incontinence was associated with higher HbA 1c levels in women with Type 1 diabetes, independent of other recognized risk factors. These results suggest the potential for women to modify their risk of urinary incontinence with improved glycaemic control.

Female genital mutilation (FGM) ranges in severity from a nick of the clitoris to partial or total removal of the external genitalia. Sexual complications after FGM include sexual dysfunction, difficult intercourse, and dyspareunia. We report a case of Type I FGM presenting as complete vaginal closure and urinary retention. A 16-year-old adolescent was referred for obliterated vagina and urinary retention. She had recurrent urinary tract infections, difficulty in voiding, and cyclic hematuria. At the age of 1 year she had been taken by her mother to a pediatric surgeon to have a Type I FGM procedure. On examination, the urethral meatus and vaginal orifices were completely closed by the FGM scar. She underwent uneventful surgical opening of the vagina. A normal vaginal orifice was created and normal flow of urine and menses occurred. Type I FGM can present as complete vaginal closure and urinary retention. Proper diagnosis and treatment are of paramount importance. © 2014 International Society for Sexual Medicine.

Study Design: Retrospective database review. Objective: Posterior/posterolateral lumbar fusion (PLF) is an effective treatment for a variety of spinal disorders; however, variations in surgical technique have different complication profiles. The aim of our study was to quantify the frequency of various complications in patients undergoing PLF with and without human recombinant bone morphogenetic protein 2 (rhBMP2). Methods: We queried the orthopedic subset of the Medicare database (PearlDiver) between 2005 and 2011 for patients undergoing PLF procedures with and without rhBMP2. Complication and reoperation rates were analyzed within 1 year of the index procedure. Complications assessed include: acute renal failure, deep vein thrombosis, dural tear, hematoma, heterotopic ossification, incision and drainage, cardiac complications, nervous system complications, osteolysis, pneumonia, pseudarthrosis, pulmonary embolism, radiculopathy, respiratory complications, sepsis, urinary retention, urinary tract infection, mechanical, and wound complications. Chi-square analysis was used to calculate the complication differences between the groups. Results: Our data revealed higher overall complication rates in patients undergoing PLF with rhBMP2 versus no_rhBMP2 (76.9% vs 68.8%, P < .05). Stratified by gender, rhBMP2 males had higher rates of mechanical complications, pseudarthrosis, and reoperations compared with no_rhBMP2 males (P < .05), whereas rhBMP2 females had higher rates of pseudarthrosis, urinary tract infection, and urinary retention compared with no_rhBMP2 females (P < .05). Conclusion: Our data revealed higher overall complication rates in PLF patients given rhBMP2 compared with no_rhBMP2. Furthermore, our data suggests that rhBMP2-associated complications may be gender specific. PMID:29662744

Prostate abscess is usually a complication of acute urinary tract infection. Invasive liver abscess syndrome is characterized with Klebsiella pneumoniae related multiple organ metastasis. Concomitant pyogenic liver abscess and prostate abscess have rarely been reported. Recurrent episode of liver abscess is even rarer. We report a 71-year-old male with acute bacterial prostate abscess and urinary tract infection caused by K. pneumoniae associated with multiple liver abscess, psoas muscle abscess and osteomyelitis. Blood culture and urine culture yielded K. pneumoniae, which confirmed the diagnosis of invasive liver abscess syndrome caused by K. pneumoniae. The patient was successfully treated with empirical antibiotics for 6 weeks. This case emphasizes the importance of timely and accurate diagnosis followed by appropriate treatment in disseminated K. pneumoniae infection to prevent significant morbidity and mortality.

[Urinary tract infections : What has been confirmed in therapy?

Urinary tract infections (UTIs) affect approximately 150 million people worldwide per year, causing annual health costs of over three billion dollars just in the USA. Every second woman experiences at least one UTI in her lifetime, with every one in four experiencing recurrence. Uncomplicated infections like single or recurrent cystitis and pyelonephritis can be distinguished from complicated disease. UTIs in men can spread to the male glands, causing prostatitis and epididymitis. Antibiotic therapy is the standard procedure for UTIs. However, the extensive and sometimes irrational use of antibiotics for the treatment of infections has led to an increase in the incidence of multiresistant pathogens in recent years. Therefore, preventive nonantibiotic approaches are of great interest. This article provides an overview of the current management of urological infections as well as an outline of nonantibiotic preventive treatment modalities.

[Reducing urinary catheter use in patients hospitalized in internal medicine departments].

PubMed

Shimoni, Zvi

2014-07-01

Clinical utility exists in certain situations for introducing a urinary catheter, but its use is the major cause of in-hospitaL acquired urinary tract infections. Furthermore, there are other complications of urinary catheterization, including urethral injury, macroscopic hematuria, and the inability to remove the catheter once introduced. Also, the in-hospital use of an indwelling urinary catheter in the elderly patient is associated with prolonged hospitalizations and an increased risk of in-hospital mortality. Although there are clinical criteria for the use of an indwelling urinary catheter, there is considerable variability in the utilization rates between hospitals and departments. For example, the rates of catheterization in general internal medicine departments usually varies between 8% to 20% and increases with the age of the patients. However, it has been shown that up to 50% of catheterizations are unjustified. Therefore, there are efforts to decrease the rate of use of urinary catheters on the one hand, and to limit the number of days with the indwelling catheter in place on the other hand. These efforts have been partially successful. The root of the problem is that the criteria for catheterization are generally vague, leading to variable interpretations. More precise definitions along with continuous monitoring will likely decrease catheterization rates without putting the patient at risk.

Anterior urethral valves (AUV) are rare entities generally described in case reports. They are an uncommon cause of lower urinary tract obstruction in children and can be difficult to diagnose. In the present study, we present our experience in four children with AUV along with a literature review. We retrospectively identified four children with AUV presented between 1998 and 2005 at age 4-9 years. Hematuria, urinary tract infection and weak voiding stream were the most common symptoms. Voiding cystourethrography (VCUG) confirmed the diagnosis of AUV. On cystourethroscopy, cusp-like valves in the anterior urethra were seen in all children. Transurethral endoscopic resection of the valves was carried out in three children using a pediatric resectoscope. In one child with a massive anterior urethral diverticulum, open resection of the valve, diverticulectomy and urethroplasty were performed. All patients were cured, none had complications as a result of surgery, and all reported a normal urinary stream at follow-up. Children with poor stream and recurrent infections should be evaluated carefully and anterior urethral valves should be considered in differential diagnosis of obstructive lesions.

Anti-Adhesion Activity of A2-type Proanthocyanidins (a Cranberry Major Component) on Uropathogenic E. coli and P. mirabilis Strains

Urinary tract infections (UTIs) are relatively common in women and may be classified as uncomplicated or complicated, depending upon the urinary tract anatomy and physiology. Acute uncomplicated cystitis (AUC) occurs when urinary pathogens from the bowel or vagina colonize the periurethral mucosa and reach the bladder. The vast majority of episodes in healthy women involving the same bacterial strain that caused the initial infection are thought to be reinfections. About 90% of AUC are caused by uropathogenic Escherichia coli (UPEC), but Proteus mirabilis also plays an important role. Several studies support the importance of cranberry (Vaccinium macrocarpon) proanthocyanidins in preventing adhesion of P-fimbriated UPEC to uroepithelial cells. In this study, we evaluated the in vitro anti-adhesion activity of A2-linked proanthocyanidins from cranberry on a UPEC and Proteus mirabilis strains and their possible influence on urease activity of the latter. A significant reduction of UPEC adhesion (up to 75%) on the HT1376 cell line was observed vs. control. For the strains of P. mirabilis there was also a reduction of adhesion (up to 75%) compared to controls, as well as a reduction in motility and urease activity. These results suggest that A2-type cranberry proanthocyanidins could aid in maintaining urinary tract health. PMID:27025740

Leprosy is an infectious disease caused by Mycobacterium leprae that affects the skin and nerves. Although curable with multidrug therapy, leprosy is complicated by acute inflammatory episodes called reactions, which are the major causes of irreversible neuropathy in leprosy that occur before, during, and even after treatment. Early diagnosis and prompt treatment of reactions reduces the risk of permanent disability. This exploratory study investigated whether urinary metabolic profiles could be identified that correlate with early signs of reversal reactions (RR). A prospective cohort of leprosy patients with and without reactions and endemic controls was recruited in Nepal. Urine-derived metabolic profiles were measured longitudinally. Thus, a conventional area of biomarker identification for leprosy was extended to non-invasive urine testing. It was found that the urinary metabolome could be used to discriminate endemic controls from untreated patients with mycobacterial disease. Moreover, metabolic signatures in the urine of patients developing RR were clearly different before RR onset compared to those at RR diagnosis. This study indicates that urinary metabolic profiles are promising host biomarkers for the detection of intra-individual changes during acute inflammation in leprosy and could contribute to early treatment and prevention of tissue damage.

Urinary tract infections (UTIs), the majority of which are caused by uropathogenic E. coli (UPEC), are extremely common infections that preferentially effect women. Additional complicating factors, such as catheterization, diabetes, and spinal cord injuries can increase the frequency and severity of UTIs. The rise of antimicrobial resistant uropathogens and the ability of this disease to chronically recur make the development of alternative preventative and therapeutic modalities a priority. The major symptoms of UTIs, urgency, frequency, and dysuria, are readouts of the autonomic nervous system (ANS) and the majority of the factors that lead to complicated UTIs have been shown to impact ANS function. This review summarizes the decades long efforts to understand the molecular mechanisms of the interactions between UPEC and the host, with a particular focus on the recent findings revealing the molecular, bacteriological, immunological and epidemiological complexity of pathogenesis. Additionally, we describe the progress that has been made in: i) generating vaccines and anti-virulence compounds that prevent and/or treat UTI by blocking bacterial adherence to urinary tract tissue and; ii) elucidating the mechanism by which anti-inflammatories are able to alleviate symptoms and improve disease prognosis. Finally, the potential relationships between the ANS and UTI are considered throughout. While these relationships have not been experimentally explored, the known interactions between numerous UTI characteristics (symptoms, complicating factors, and inflammation) and ANS function suggest that UTIs are directly impacting ANS stimulation and that ANS (dys)function may alter UTI prognosis.

Background. Pelvic exenteration and multivisceral resection in colorectal have been described as a curative and palliative intervention. Urinary tract reconstruction in a pelvic exenteration is achieved in most cases with an ileal conduit of Bricker, although different urinary reservoirs have been described. Methods. A retrospective and observational study of six patients who underwent a pelvic exenteration and urinary tract reconstruction with a double barreled wet colostomy (DBWC) was done, describing the preoperative diagnosis, the indication for the pelvic exenteration, the complications associated with the procedure, and the followup in a period of 5 years. A literature review of the case series reported of the technique was performed. Results. Six patients had a urinary tract reconstruction with the DBWC technique, 5 male patients and one female patient. Age range was from 20 to 77 years, with a medium age 53.6 years. The most frequent complication presented was a pelvic abscess in 3 patients (42.85%); all complications could be resolved with a conservative treatment. Conclusion. In the group of our patients with pelvic exenteration and urinary tract reconstruction with a DBWC, it is a safe procedure and well tolerated by the patients, and most of the complications can be resolved with conservative treatment.

The aim of this study was to assess the treatment patterns and 3-12-month complication rates associated with receiving prostate cryotherapy in a population-based study. Men >65 years diagnosed with incident localized prostate cancer in Surveillance Epidemiology End Results (SEER)-Medicare-linked database from 2004 to 2005 were identified. A total of 21,344 men were included in the study, of which 380 were treated initially with cryotherapy. Recipients of cryotherapy versus aggressive forms of prostate therapy (ie, radical prostatectomy or radiation therapy) were more likely to be older, have one co-morbidity, low income, live in the South and be diagnosed with indolent cancer. Complication rates increased from 3 to 12 months following cryotherapy. By the twelfth month, the rates for urinary incontinence, lower urinary tract obstruction, erectile dysfunction and bowel bleeding reached 9.8, 28.7, 20.1 and 3.3%, respectively. Diagnoses of hydronephrosis, urinary fistula or bowel fistula were not evident. The rates of corrective invasive procedures for lower urinary tract obstruction and erectile dysfunction were both <2.9% by the twelfth month. Overall, complications post-cryotherapy were modest; however, diagnoses for lower urinary tract obstruction and erectile dysfunction were common.

Sacral neuromodulation is well established in the treatment of refractory, non-neurogenic lower urinary tract dysfunction, but its efficacy and safety in patients with lower urinary tract dysfunction of neurological origin is unclear. Only few case series have been reported for multiple sclerosis. We prospectively evaluated the efficacy and safety of sacral neuromodulation in patients with multiple sclerosis. Seventeen patients (13 women, 4 men) treated with sacral neuromodulation for refractory neurogenic lower urinary tract dysfunction caused by multiple sclerosis were prospectively enrolled (2007-2011). Patients had to have stable disease and confirmed neurogenic lower urinary tract dysfunction. Voiding variables, adverse events, and subjective satisfaction were assessed. Sixteen (94 %) patients had a positive test phase with a >70 % improvement. After implantation of the pulse generator (InterStim II), the improvement in voiding variables persisted. At 3 years, the median voided volume had improved significantly from 125 (range 0 to 350) to 265 ml (range 200 to 350) (p < 0.001), the post void residual from 170 (range 0 to 730) to 25 ml (range 0 to 300) (p = 0.01), micturition frequency from 12 (range 6 to 20) to 7 (range 4 to 12) (p = 0.003), and number of incontinence episodes from 3 (range 0 to 10) to 0 (range 0 to 1) (p = 0.006). The median subjective degree of satisfaction was 80 %. Only two patients developed lack of benefit. No major complications occurred. Chronic sacral neuromodulation promises to be an effective and safe treatment of refractory neurogenic lower urinary tract dysfunction in selected patients with multiple sclerosis.

Complicated pregnancies in inherited distal renal tubular acidosis: importance of acid-base balance.

Inherited distal renal tubular acidosis (dRTA) is caused by impaired urinary acid excretion resulting in hyperchloremic metabolic acidosis. Although the glomerular filtration rate (GFR) is usually preserved, and hypertension and overt proteinuria are absent, it has to be considered that patients with dRTA also suffer from chronic kidney disease (CKD) with an increased risk for adverse pregnancy-related outcomes. Typical complications of dRTA include severe hypokalemia leading to cardiac arrhythmias and paralysis, nephrolithiasis and nephrocalcinosis. Several physiologic changes occur in normal pregnancy including alterations in acid-base and electrolyte homeostasis as well as in GFR. However, data on pregnancy in women with inherited dRTA are scarce. We report the course of pregnancy in three women with hereditary dRTA. Complications observed were severe metabolic acidosis, profound hypokalemia aggravated by hyperemesis gravidarum, recurrent urinary tract infection (UTI) and ureteric obstruction leading to renal failure. However, the outcome of all five pregnancies (1 pregnancy each for mothers n. 1 and 2; 3 pregnancies for mother n. 3) was excellent due to timely interventions. Our findings highlight the importance of close nephrologic monitoring of women with inherited dRTA during pregnancy. In addition to routine assessment of creatinine and proteinuria, caregivers should especially focus on acid-base status, plasma potassium and urinary tract infections. Patients should be screened for renal obstruction in the case of typical symptoms, UTI or renal failure. Furthermore, genetic identification of the underlying mutation may (a) support early nephrologic referral during pregnancy and a better management of the affected woman, and (b) help to avoid delayed diagnosis and reduce complications in affected newborns.

To assess postoperative complications, improvement of pain symptoms and residual urinary functional symptoms after surgery for deep infiltrative endometriosis affecting ureter or bladder. Retrospective study of complications (Clavien-Dindo classification), pain (visual analog scale [VAS]) and urinary functional symptoms (Urinary Symptom Profile questionnaire [USP]) of patients surgically treated between 2007 and 2015 in University Hospitals of Lyon. Among 31 patients with endometriosis involving the bladder, 83.9% had a partial cystectomy and 16.1% an extra-mucosal resection. Among patients (n=20) with ureteral involvement, 85% had ureterectomy with ureterocystoneostomy and 15% had only ureterolysis. Grade III postoperative complications occurred in 6% and 0% of patients with bladder or ureteral surgery, respectively and no grade IV or V complications were reported. Mean bladder VAS dropped from 5.3±4.2 to 0.3±0.9 after a follow-up of 42 months (P<0.0001). In patients with ureteral involvement, mean flank VAS dropped from 3.6 to 0.9 after a follow-up of 33 months (P<0.0005). Mean postoperative USP score for dysuria and detrusor overactivity were 1.35/9 and 2.48/21 in case of bladder involvement, and 1.10/9 and 2.15/21 in case of ureteral involvement. Multidisciplinary surgical management of deep infiltrative endometriosis affecting urinary tract was associated to a low risk of severe postoperative complications and to a long-term significant improvement of pain symptoms without significant residual functional urinary symptoms.

Contemporary transcatheter aortic valve implantation (TAVI) devices and approach present opportunities to review historical practices initially informed by early treatment development and cardiac surgery. The avoidance of urinary catheterization in the older TAVI population is a strategy to minimize in-hospital complications. The purpose of the study was to explore elimination-related complications following the phased implementation of a default strategy of avoiding urinary catheterization in patients undergoing transfemoral (TF) TAVI. We conducted an observational study using a retrospective chart review of patients treated between 2011 and 2013 to identify patient characteristics, peri-procedure details, in-hospital outcomes and elimination-related complications in patients who did or did not receive a peri-procedure indwelling catheter. Descriptive analyses were used to report differences between the groups; we conducted a regression analysis to explore the relationship between the practice of urinary catheterization and total procedure time. Of the 408 patients who underwent TF TAVR, 188 (46.1%) received a peri-procedure indwelling urinary catheter and 220 (53.9%) did not. There was no difference in in-hospital mortality (2.2%), disabling stroke (0.5%), or other major cardiac adverse events. The avoidance of a urinary catheter resulted in significantly lower rates of urinary tract infection requiring a new antibiotic regimen (1.4% versus 6.1%, p = 0.014), haematuria documented by medicine or nursing (3.7% versus 17.6%, p = 0.001), and the need for continuous bladder irrigation (2.7% versus 0%, p = 0.027). The avoidance of a urinary catheter may contribute to improved outcomes in patients undergoing TAVI. The intervention should be further evaluated within the broader study of minimalist TAVI.

Urinary tract infections (UTIs) are the second most common nosocomially acquired infections, responsible for approximately 21% of healthcare-associated pyelonephritis and 10.5% of urosepsis. Worldwide trends of increasing resistance resulted in the urgent need for novel antimicrobials that would be active against bacterial resistance mechanisms as an alternative to carbapenems, which are considered last resort antibiotics. The current review is based on a Medline search of published English language literature and contains summary information regarding the evaluation of pharmacologic properties, efficacy, safety and activity of ceftolozane+tazobactam against common bacterial resistance mechanisms. In vivo and vitro studies demonstrated high activity of ceftolozane+tazobactam in the combination of 2:1 against a variety of uropathogens, including ESBL-producers. Phase II and Phase III studies performed in patients with complicated UTIs showed good tolerability and safety of ceftolozane+tazobactam when prescribed intravenously 1.5 g every 8 h for 7 days and at least non-inferiority to a high dose (750 mg) of levofloxacin. The pharmacokinetics of ceftolozane+tazobactam makes it a worthy alternative to carbapenems in cases of complicated UTIs, also caused by multidrug resistant uropathogens.

To analyze the related influencing factors of urinary tract infection in patients undergoing transurethral resection of the prostate (TURP). A total of 343 patients with benign prostatic hyperplasia admitted to this hospital from January 2013 to December 2016, were selected and treated by TURP. Patients were divided into infection group and non-infection group according to the occurrence of urinary tract infection after operation. The possible influencing factors were collected to perform univariate and multivariate logistic regression analysis. There were 53 cases with urinary tract infection after operation among 343 patients with benign prostatic hyperplasia, accounting for 15.5%. The univariate analysis displayed that the occurrence of urinary tract infection in patients undergoing TURP was closely associated with patient's age ≥ 65 years old, complicated diabetes, catheterization for urinary retention before operation, no use of antibiotics before operation and postoperative indwelling catheter duration ≥ 5 d (p < 0.05). Multivariate logistic regression analysis revealed that age ≥ 65 years old, complicated diabetes, catheterization before operation, indwelling catheter duration ≥ 5 d and no use of antibiotics before operation were risk factors of urinary tract infection in patients receiving TURP (p < 0.05). The patient's age ≥ 65 years old, catheterization before operation, complicated diabetes and long-term indwelling catheter after operation, can increase the occurrence of urinary tract infection after TURP, while preoperative prophylactic utilization of anti-infective drugs can reduce the occurrence of postoperative urinary tract infection.

Currarino syndrome (triad) is an extremely rare condition characterized by presacral mass, anorectal malformation, and sacral bone deformation. The complete form of this syndrome displays all three irregularities. Herein, we report a male case who was admitted to our hospital with symptoms of urinary system infection and persistent constipation 2 years after colostomy operation performed with the indication of rectovestibular fistula and anal atresia, diagnosed as Currarino syndrome based on imaging modalities. In a patient who was admitted because of the presence of anal atresia, in order to preclude potential complications, probable concomitancy of this syndrome should not be forgotten. Early diagnosis is important for the prevention of meningitis, urinary tract infections, and malignant change. PMID:27081429

There is a projected increase in lower urinary tract obstruction by 2018, especially in the developing economies of Asia and Africa. However in many of these countries, the problems encountered both by the patients and the clinicians are not well documented. Our aims are, to prospectively analyse the management of urinary retention, the associated difficulties, and complications in our setting, where access to investigative modalities such as Computerize Tomography and Magnetic Resonance Imaging are not available. The study was approved by the University Of Calabar Teaching Hospital ethical committee. A validated Proforma was used to collect data from all patients who were clinically diagnosed with urinary retention based on history, and physical examination, from July 2009 to June 2010. Data collected from the 1st of July 2009 to the 30th of June 2010, include demographics, findings on physical examination, previous medical history and co-morbid conditions. The results of investigations done such as: urinalysis, full blood count, electrolytes, urea and creatinine, intravenous urography, trans- abdominal ultrasonography, chest X-ray and histology of trans-rectal biopsies of the prostate . The total number of new patients seen, including those with urinary retention during the study was documented. The retentions were also classified into acute and chronic. All the patients were followed up throughout the study. The data was analysed using Epi-Info statistical program version 3.4 of 2007 to analyse the data, estimating averages, mean, median and percentages. The total number of new patients seen, including those with urinary retention was Seventy thousand, one hundred and thirty nine (70,139).Of this number, hundred and fifty nine (0.23%), presented with urinary retention; 145 (91.2%) were acute, and14 (8.8%) were chronic. The male: female ratio was 39:1.The patients ages ranged from 4 to 94 years, with a mean of 53.7±11.2. Seventy seven [48.4%] of them were in the 6(th) and 7(th) decades of life. The common causes were; prostatic diseases [BPH and cancer of the prostate] 77.0%, infections 75.8%, trauma 12.1%, and congenital 12.1%. Urinary retention was relieved by: indwelling urethral catheterization [IUC] 120 patients (75.5%), supra- pubic cystostomy [SC] 34 (21.4%) and intermittent urethral catheterization [IC] 5 (3.1%). The most frequently encountered complications include pyuria (18.2%), pericatheter sepsis 17.5%, and haemorrhage during change of catheter 16.8% [figure 2].

[Urinary catheter biofilm infections].

PubMed

Holá, V; Růzicka, F

2008-04-01

Urinary tract infections, most of which are biofilm infections in catheterized patients, account for more than 40% of hospital infections. Bacterial colonization of the urinary tract and catheters causes not only infection but also other complications such as catheter blockage by bacterial encrustation, urolithiasis and pyelonephritis. About 50% of long-term catheterized patients face urinary flow obstruction due to catheter encrustation, but no measure is currently available to prevent it. Encrustation has been known either to result from metabolic dysfunction or to be of microbial origin, with urease positive bacterial species implicated most often. Infectious calculi account for about 15-20% of all cases of urolithiasis and are often associated with biofilm colonization of a long-term indwelling urinary catheter or urethral stent. The use of closed catheter systems is helpful in reducing such problems; nevertheless, such a system only delays the inevitable, with infections emerging a little later. Various coatings intended to prevent the bacterial adhesion to the surface of catheters and implants and thus also the emergence of biofilm infections, unfortunately, do not inhibit the microbial adhesion completely and permanently and the only reliable method for biofilm eradication remains the removal of the foreign body from the patient.

Flomoxef (6315-S, FMOX), a new oxacephem antibiotic was studied clinically in 27 patients with complicated urinary tract infections. FMOX was intravenously administered at a dose of 1.0 g twice daily for 5 days. Clinical effect of FMOX on patients with complicated urinary tract infections were excellent in 11.5%, moderate in 57.7% and overall clinical efficacy rate was 69.2%. During the treatment with FMOX, urticaria was observed in 1 case. In laboratory tests, a decrease of RBC, Hb and Ht in 1 case, a decrease of WBC in 1 case and an elevation of GPT in another case were observed. But these abnormal values were slight and transient.

Abstract Objective: In the antibiotic era, purulent pericarditis is a rare entity. However, there are still reports of cases of the disease, which is associated with high mortality, and most such cases are attributed to delayed diagnosis. Approximately 40-50% of all cases of purulent pericarditis are caused by Gram-positive bacteria, Streptococcus pneumoniae in particular. Methods: We report four cases of pneumococcal pneumonia complicated by pericarditis, with different clinical features and levels of severity. Results: In three of the four cases, the main complication was cardiac tamponade. Microbiological screening (urinary antigen testing and pleural fluid culture) confirmed the diagnosis of severe pneumococcal pneumonia complicated by purulent pericarditis. Conclusions: In cases of pneumococcal pneumonia complicated by pericarditis, early diagnosis is of paramount importance to avoid severe hemodynamic compromise. The complications of acute pericarditis appear early in the clinical course of the infection. The most serious complications are cardiac tamponade and its consequences. Antibiotic therapy combined with pericardiocentesis drastically reduces the mortality associated with purulent pericarditis. PMID:26398760

In adults nephrectomy is under the purview of urologists, but pediatric urologists and pediatric general surgeons perform extirpative renal surgery in children. We compared the contemporary performance and outcome of all-cause nephrectomy at pediatric hospitals as performed by pediatric urologists and pediatric general surgeons. We queried the Pediatric Health Information System to identify patients 0 to 18 years old who were treated with nephrectomy between 2004 and 2013 by pediatric urologists and pediatric general surgeons. Data points included age, gender, severity level, mortality risk, complications and length of stay. Patients were compared by APR DRG codes 442 (kidney and urinary tract procedures for malignancy) and 443 (kidney and urinary tract procedures for nonmalignancy). Pediatric urologists performed more all-cause nephrectomies. While pediatric urologists were more likely to operate on patients with benign renal disease, pediatric general surgeons were more likely to operate on children with malignancy. Patients on whom pediatric general surgeons operated had a higher average severity level and were at greater risk for mortality. After controlling for differences patients without malignancy operated on by pediatric urologists had a shorter length of stay, and fewer medical and surgical complications. There was no difference in length of stay, or medical or surgical complications in patients with malignancy. Overall compared to pediatric general surgeons more nephrectomies are performed by pediatric urologists. Short-term outcomes, including length of stay and complication rates, appear better in this data set in patients without malignancy who undergo nephrectomy by pediatric urologists but there is no difference in outcomes when nephrectomy is performed for malignancy.

The aim of this study was to assess the treatment patterns and 3 to 12-month complication rates associated with receiving prostate cryotherapy in a population-based study. Men > 65 years diagnosed with incident localized prostate cancer in Surveillance Epidemiology End Results (SEER) - Medicare linked database from 2004 to 2005 were identified. A total of 21,344 men were included in the study, of which 380 were treated initially with cryotherapy. Recipients of cryotherapy versus aggressive forms of prostate therapy (i.e. radical prostatectomy or radiation therapy) were more likely to be older, have one co-morbidity, low income, live in the South, and be diagnosed with indolent cancer. Complication rates increased from 3 to 12 months following cryotherapy. By the twelfth month, the rates for urinary incontinence, lower urinary tract obstruction, erectile dysfunction, and bowel bleeding reached 9.8%, 28.7%, 20.1%, and 3.3%, respectively. Diagnoses of hydronephrosis, urinary fistula, or bowel fistula were not evident. The rates of corrective invasive procedures for lower urinary tract obstruction and erectile dysfunction were both <2.9% by the twelfth month. Overall, complications post cryotherapy were modest; however, diagnoses for lower urinary tract obstruction and erectile dysfunction were common. PMID:21519347

Complications of bladder distension during retrograde urethrography.

A severe, ulcerative cystitis that resulted in macroscopic hematuria occurred in 8 of 20 healthy dogs undergoing a series of diagnostic tests. Four of the remaining 12 dogs had mild bladder lesions consisting of submucosal edema and hemorrhage. Nine of the 20 dogs developed urinary tract infection after the procedures. These complications seemed associated with the radiographic technique of retrograde urethrography performed when the urinary bladder was distended. To test this hypothesis, retrograde urethrography was performed on 5 additional dogs. With the bladder undistended, no complications occurred. However, distention of these same dogs' bladders for 1 minute or less with sterile lactated Ringer's solution administered through a Foley catheter in the penile urethra resulted in a macroscopic hematuria in all 5 dogs which persisted for 24 hours. A microscopic hematuria continued for 5 days. One dog developed a bacterial urinary tract infection. A severe fibrinopurulent cystitis was present at necropsy of 2 dogs 2 days after distention. The morphologic changes in the bladder gradually diminished over 7 days, but mild submucosal edema and hemorrhage were still present when 2 dogs were necropsied, 7 days after distention. These studies indicated that retrograde urethrography in dogs may be complicated by hemorrhagic cystitis and urinary tract infection if performed with urinary bladder distention.

To determine the outcomes of pregnancy and cesarean delivery (CD) in women with neuropathic bladder (NB) and pediatric lower urinary tract reconstruction (LUTR) as these women often have normal fertility and may become pregnant. We reviewed consecutive patients with NB due to spinal dysraphism who underwent LUTR, became pregnant, and had a CD at our institution from July 2001 to June 2016. We collected data on demographics, hydronephrosis, symptomatic urinary tract infection, continence, and catheterization during pregnancy. CD data included gestational age, abdominal or uterine incisions, and complications. We identified 18 pregnancies in 11 women. Fifteen live newborns were delivered via CD (53.3% term births). Thirteen of 15 patients (86.7%) developed new (10) or worsening (3) hydronephrosis. Six of 13 patients (46.2%) underwent nephrostomy tube placement. Eight of 15 patients (53.3%) developed difficulty catheterizing (66.7% via native urethra, 44.4% via catheterizable channel); 50.0% of patients required an indwelling catheter. Five of 15 patients (33.3%) developed urinary incontinence during pregnancy. Ten of 15 patients (66.7%) had a urinary tract infection (30.0% febrile). A urologist was present for all CDs: 5 were scheduled, 10 occurred emergently. Complications occurred in 40.0% (5 cystotomies, 1 bowel deserosalization, 1 vaginal laceration). All cystotomies occurred during emergent CD. Three patients (20.0%) developed urinary fistulae after emergent CD. Women with NB and LUTR have high rates of complications during pregnancy and CD, despite routine involvement of urologists. Women with prolonged labor, previous CD, or those with a history of noncompliance developed the worst complications. Based on our experience, a urologist should always be present and participate in the CD. Copyright © 2018 Elsevier Inc. All rights reserved.

A case of sacral herpes zoster infection in a 56-year-old man with the complication of loss of urinary voiding sensation is presented. He had typical herpes zoster eruption on the left S2 dermatome, hypalgesia of the S1-S4 dermatomes, and absence of urinary voiding sensation. There was no other urinary symptom at the first medical examination. Urinary complications associated with herpes zoster are uncommon, but two types, acute cystitis and acute retention, have been recognized. No cases of loss of urinary voiding sensation due to herpes zoster have been reported. In this case, hypalgesia of the sacral dermatomes was mild compared to the marked loss of urethral sensation. This inconsistency is explained by the hypothesis that the number of urethral fibers is very small as compared to that of cutaneous fibers, therefore, urethral sensation would be more severely disturbed than cutaneous sensation.

To investigate the incidence and microbiology of urinary tract infection (UTI) within 90 days following radical cystectomy (RC) and urinary diversion. We reviewed 1133 patients who underwent RC for bladder cancer at our institution between 2003 and 2013; 815 patients (72%) underwent orthotopic diversion, 274 (24%) ileal conduit, and 44 (4%) continent cutaneous diversion. 90-day postoperative UTI incidence, culture results, antibiotic sensitivity/resistance and treatment were recorded through retrospective review. Fisher's exact test, Kruskal-Wallis test, and multivariable analysis were performed. A total of 151 urinary tract infections were recorded in 123 patients (11%) during the first 90 days postoperatively. 21/123 (17%) had multiple infections and 25 (20%) had urosepsis in this time span. Gram-negative rods were the most common etiology (54% of positive cultures). 52% of UTI episodes led to readmission. There was no significant difference in UTI rate, etiologic microbiology (Gram-negative rods, Gram-positive cocci, fungi), or antibiotic sensitivity and resistance patterns between diversion groups. Resistance to quinolones was evident in 87.5% of Gram-positive and 35% of Gram-negative bacteria. In multivariable analysis, Charlson Comorbidity Index > 2 was associated with higher 90-day UTI rate (OR = 1.8, 95% CI 1.1-2.9, p = 0.05) and Candida UTI (OR 5.6, 95% CI 1.6-26.5, p = 0.04). UTI is a common complication and cause of readmission following radical cystectomy and urinary diversion. These infections are commonly caused by Gram-negative rods. High comorbidity index is an independent risk factor for postoperative UTI, but diversion type is not.

The unexplored relationship between urinary tract infections and the autonomic nervous system.

Urinary tract infections (UTIs), the majority of which are caused by uropathogenic E. coli (UPEC), are extremely common infections that preferentially effect women. Additional complicating factors, such as catheterization, diabetes, and spinal cord injuries can increase the frequency and severity of UTIs. The rise of antimicrobial resistant uropathogens and the ability of this disease to chronically recur make the development of alternative preventative and therapeutic modalities a priority. The major symptoms of UTIs, urgency, frequency, and dysuria, are readouts of the autonomic nervous system (ANS) and the majority of the factors that lead to complicated UTIs have been shown to impact ANS function. This review summarizes the decades' long efforts to understand the molecular mechanisms of the interactions between UPEC and the host, with a particular focus on the recent findings revealing the molecular, bacteriological, immunological and epidemiological complexity of pathogenesis. Additionally, we describe the progress that has been made in: i) generating vaccines and anti-virulence compounds that prevent and/or treat UTI by blocking bacterial adherence to urinary tract tissue and; and ii) elucidating the mechanism by which anti-inflammatories are able to alleviate symptoms and improve disease prognosis. Finally, the potential relationships between the ANS and UTI are considered throughout. While these relationships have not been experimentally explored, the known interactions between numerous UTI characteristics (symptoms, complicating factors, and inflammation) and ANS function suggest that UTIs are directly impacting ANS stimulation and that ANS (dys)function may alter UTI prognosis.

Sling operations have been performed for over 15 years. In recent years these operations have become the gold standard in the treatment of stress urinary incontinence (SUI) due to their efficacy safety and low invasiveness. Approximately 4% of women will undergo a surgery for SUI in the course of their life. As with any surgical intervention, there may be some technical problems, as well as intra- and postoperative complications, the most common of which is bladder injury Other complications encountered during mid-urethral slings procedures include bleeding (retropubic or vaginal hematomas), urethral perforation, urinary tract infections, postoperative vaginal or urethral erosions, bowel perforation, chronic pelvic pain, wound infection, nerve injury transient and persistent voiding dysfunction such as de novo urgency incomplete bladder emptying or urinary retention. Below we present a case of a patient with diagnosed vesicovaginal fistula after sling operation (TVT-tension-free vaginal tape). Upon admission the patient reported dysuria, persistent urinary leakage and abnormal, abundant vaginal discharge. Case report and review of literature concerning surgical treatment of stress urinary incontinence and its complications. Analysis of medical documentation of the patient treated at the Second Department of Gynecology Medical University of Lublin. Review of abstracts or papers in the Medline database related to surgical treatment of urinary incontinence and its complications. Bladder perforation is one of the most common complications of the retropubic approach for MUS placement. The presence of mesh within the bladder may arise from direct bladder perforation or from subsequent erosion of the sling. Such lesions do not cause any serious health consequences for patients on condition they are detected intraoperatively and appropriately repaired, but when unrecognized, they results in the development of considerable symptoms and negatively influence the quality of patient life. Improperly treated, it can lead to development of an abnormal communication between the urinary bladder and the anterior wall of the vagina -vesicovaginal fistula. We should suspect unrecognized bladder injury in case of patients with any persistent voiding symptoms after a sling procedure such as long lasting dysuria, persistent urinary leakage, hematuria, recurrent infections, chronic pain and voiding difficulties. Diagnosis and treatment of vesicovaginal fistula is long lasting and difficult for the patient and the surgeon. Füth-Mayo operation is an effective treatment method for the majority of vesicovaginal fistulas. During this operation we suture all layers of fistula separately (bladder perivesical fascia and vaginal wall). Although with this operation we solve one problem, the patient still might suffer from recurrent SUI. Alternative methods of treatment which can be offered to patients after unsuccessful SUI operation are periurethral injections with bulking agents or electrical stimulation of the pelvic floor muscles. Both methods are effective in the therapy of recurrent SUI. In our case periurtehral injection of Bulkamid did not provide a total cure. Therefore, we completed the treatment with electrical stimulation of the pelvic floor muscles using patient-controlled electrodes placed in the vagina to stimulate muscles with current frequency of 50 Hz, amperage between 0-60 mA and duration of 250 micros. This procedure produced a series of changes in the stimulated area and enabled to cure the incontinence.

The importance of constipation lies in its frequency, even among the healthy. The incidence of constipation in oncological patients is 70-80% in the final stage, 40-50% in advanced disease, and 90% in patients with aggressive cancer. This disorder is not only uncomfortable for the patient but also causes complications. Prolonged constipation can cause abdominal pain and even increase the pain caused by the tumor and stronger pain relief can be required when the constipation is unresolved. Among the complications that can occur are intestinal obstruction, diarrhea by spillage, urinary dysfunction, anorexia, nausea and vomiting, restlessness, malaise, and confusion. When analyzing this problem, we aim to unify criteria and nursing interventions, emphasize the importance of prevention, and solve the problem. Health education of both the patient and the main caregiver aid control of this disorder after discharge. The patient will be able to identify the appearance of constipation, its causes and symptoms and will be familiar with the treatment and when and where to go to review it.

Bekelman, Justin E., E-mail: bekelman@uphs.upenn.edu; Abramson Cancer Center, University of Pennsylvania, Philadelphia, PA; Leonard Davis Institute of Health Economics, University of Pennsylvania, Philadelphia, PA

Purpose: There is little evidence comparing complications after intensity-modulated (IMRT) vs. three-dimensional conformal radiotherapy (CRT) for prostate cancer. The study objective was to test the hypothesis that IMRT, compared with CRT, is associated with a reduction in bowel, urinary, and erectile complications in elderly men with nonmetastatic prostate cancer. Methods and Materials: We undertook an observational cohort study using registry and administrative claims data from the SEER-Medicare database. We identified men aged 65 years or older diagnosed with nonmetastatic prostate cancer in the United States between 2002 and 2004 who received IMRT (n = 5,845) or CRT (n = 6,753).more » The primary outcome was a composite measure of bowel complications. Secondary outcomes were composite measures of urinary and erectile complications. We also examined specific subsets of bowel (proctitis/hemorrhage) and urinary (cystitis/hematuria) events within the composite complication measures. Results: IMRT was associated with reductions in composite bowel complications (24-month cumulative incidence 18.8% vs. 22.5%; hazard ratio [HR] 0.86; 95% confidence interval [CI], 0.79-0.93) and proctitis/hemorrhage (HR 0.78; 95% CI, 0.64-0.95). IMRT was not associated with rates of composite urinary complications (HR 0.93; 95% CI, 0.83-1.04) or cystitis/hematuria (HR 0.94; 95% CI, 0.83-1.07). The incidence of erectile complications involving invasive procedures was low and did not differ significantly between groups, although IMRT was associated with an increase in new diagnoses of impotence (HR 1.27, 95% CI, 1.14-1.42). Conclusion: IMRT is associated with a small reduction in composite bowel complications and proctitis/hemorrhage compared with CRT in elderly men with nonmetastatic prostate cancer.« less

Two children who had undergone a transappendicular urinary diversion (type Mitrofanoff) developed bladder rupture, one following abdominal trauma, 4 months after the operation and the other following traumatic self-catheterization at 4 years. The clinical history and standard radiological examinations (ultrasonography, cystography) confirmed the diagnosis of urinary peritonitis. Emergency surgical repair was possible in both cases with an uneventful postoperative course. This serious and rare complication requires emergency surgery and justifies rigorous selection of children suitable for this type of diversion giving preference to increased bladder neck resistance over bladder neck closure.

The present article describes the case of two men, 18 and 30 years respectively, in whom renal insufficiency was discovered incidently. In the two cases renography showed 46 and 30% of expected function given two healthy kidneys. They had neither experienced clinical symptoms of urinary tract disorder, been operated upon, nor endoscopically examined. Micturition was normal without any sign of vesicourethral dysfunction. Micturition cystography revealed severe vesicoureteral reflux in both patients. They were treated by bilateral ureterovesical reimplantation. The cases presented here show that primary vesicoureteral reflux complicated by impaired renal function can be revealed in adults who have had no symptoms of urinary tract disorder. In these cases the probable cause of renal damage is the mechanical effect of reflux ("water-hammer effect") alone.

Penile fracture with concomitant complete urethral disruption is an uncommon urologic disorder. Data about the treatment and outcome measurements of this condition are scarce in the literature. The aim of the present study is to evaluate the long term urinary and sexual functions of patients with penile fracture associated with complete urethral injury after immediate surgical reconstruction. Twelve patients met our inclusion criteria and were included in this retrospective case series study; however, one was lost during follow-up. Patient's medical records were reviewed and all patients were interviewed for clinical evaluation. Urinary function was assessed by history, uroflometry and retrograde urethrography, while, sexual function was assessed by questionnaire (Sexual Health Inventory for Men) and penile Doppler for patients with erectile dysfunction. Patients' mean age was 32.3 ± 7.5 years (range 21-43) and the mean follow-up period was 72.6 ± 45.4 months (range 14-187). Vigorous sexual intercourse was the main cause in 91% of our patients. No serious long term complications was found. Only 1 patient (9%) suffered from anterior urethral stricture, 1 patient (9%) complained of weak erection, 3 patients (27%) had a palpable fibrosis and 2 patients (18%) reported a slight penile curvature during erection. Ninety one percent of all our patients maintained their normal urinary and sexual functions. On the long term follow-up, most of the patients maintained their normal erectile and voiding functions with no harmful long-term complications. We advocate immediate surgical intervention and reconstruction of both corpora cavernous and urethra as a first line treatment for those patients.

To evaluate the development, safety and efficacy of percutaneous nephrolithotomy(PNL) for management of upper urinary tract calculi in pediatric patients. In the study, 77 pediatric patients undergoing 87 PNLs through mini or standard tract for upper urinary tract calculi between January 2005 and December 2016 in Peking University People's hospital were reviewed, including 69 renal calculi, 6 upper ureteral calculi, 12 renal and upper ureteral calculi, 35 single calculi, 43 multiple calculi and 9 staghorn calculi. The development and efficacy of PNL in pediatric patients were studied by analyzing the characteristics and clinical indexes, and by reviewing the associated literature. The Clavien classification system was used to evaluate the complications after PNL. A total of 87 PNLs were performed in 77 pediatric patients. Eighty-one upper urinary tract calculi were managed through a single tract(93.1%), 5 pediatric patients were managed through 2 tracts(5.7%), and 1 pediatric patient was managed through 3 tracts(1.2%). The mean operating time was (77.0±29.8) min. The stone-free rate after one session was 100% for single calculi and 71.2% for multiple or staghorn calculi, 5(5.8%) children underwent auxiliary procedure to remove the residual calculi and the final stone-free rate of PNL was 88.5%. One of the main complications of pediatric PNL was fever. Sixteen (18.4%) had moderate fever(38-39 °C), 5 (5.7%) had high fever (39-40 °C) and there were no severe complications of infection, such as sepsis or septic shock. The mean hemoglobin loss was (10.3±16.1) g/L and the serum creatinine rise was (7.0±13.3) μmol/L. One(1.2%) pediatric patient suffered ureteroscopic lithotripsy because of the obstruction by the residual stone in ureter. No injury of organs or retroperitoneal urinary extravasation occurred. General assessment of the complications showed Clavien grade I complications in 14 (16.1%) pediatric patients, grade II in 7(8.0%) children and grade III in 1(1.2%) children. There was no grade IV or V complications. The overall complication rate was 25.3%. PNL for management of upper urinary tract calculi in pediatric patients is effective. Complications after PNL, as assessed with Clavien classification system, are mild and PNL in pediatric patients is safe.

To determine if postoperative urinary retention and urinary tract infections (UTIs) were predictors of future mesh complications requiring surgical intervention after midurethral sling (MUS). Administrative data in Ontario, Canada, between 2002 and 2013 were used to identify all women who underwent a mesh-based MUS. The primary outcome was revision of the transvaginal mesh sling (including mesh removal/erosion/fistula, or urethrolysis). Two potential risk factors were analyzed: postoperative retention (within 30 days of procedure) and number of postoperative emergency room visits or hospital admissions for UTI symptoms. A total of 59,556 women had a MUS, of which 1598 (2.7%) required revision surgery. Of the 2025 women who presented to the emergency room or were admitted to hospital for postoperative retention, 212 (10.5%) required operative mesh revision. Of the 11,747 patients who had at least one postoperative UTI, 366 (3.1%) patients required operative mesh revision. In adjusted analysis, postoperative retention was significantly predictive of future reoperation (hazard ratio [HR] 3.46, 95% confidence interval [CI] 2.97-4.02), and this difference persisted when urethrolysis was excluded as a reason for sling revision (HR 3.08, 95% CI 2.62-3.63). Similarly, in adjusted analysis, each additional postoperative hospital visit for UTI symptoms increased the risk for surgical intervention for mesh complications (HR 1.74, 95% CI 1.61-1.87). Postoperative urinary retention and hospital presentation for UTI symptoms are associated with an increased risk of reoperation for MUS complications. These patients should be followed and investigated for mesh complications when appropriate. Copyright © 2016 Elsevier Inc. All rights reserved.

Recurrent uncomplicated urinary tract infections in women: a review.

PubMed

Nosseir, Sandy B; Lind, Lawrence R; Winkler, Harvey A

Recurrent urinary tract infections most often present with symptoms of irritative voiding. In most cases, they are caused by reinfection with a previously isolated organism. Patients with one or more symptoms of uncomplicated recurrent urinary tract infection should undergo thorough examination and screening for underlying comorbidities that increase susceptibility. When frequent reinfections, empiric treatment relapse, persistent infections, or risk factors for complicated infections are encountered, patients may benefit from urodynamics, cystoscopy, renal ultrasound, intravenous urogram, or voiding cystourethrogram to evaluate for anatomic, functional, or metabolic abnormalities affecting the urinary tract (e.g., stones, stricture, obstruction, vesicoureteral reflux, lesions, detrusor underactivity). These patients may benefit from culture-guided empiric treatment and further evaluation by urology, nephrology, or infectious disease specialists. In patients with a history of uncomplicated urinary tract infections, empiric treatment guided by local antimicrobial resistance may efficiently treat a suspected recurrence. After successful treatment of the acute infection, postcoital prophylaxis, continuous prophylaxis, or self-start empiric treatment may be selected based on frequency of recurrent infections, temporal relation to intercourse, and patient characteristics. Ancillary measures such as probiotics, cranberry products, or local estrogen replacement may also be considered. This article will review the current definition, epidemiology, pathogenesis, diagnosis, work-up, treatment, treatment side effects, and prevention of recurrent urinary tract infections in women. A suggested algorithm for evaluation and treatment based on current literature is provided.

Results of treatment of 277 patients with colorectal cancer stage IV complicated by the urinary tract invasion, were analyzed. Men were 168 (60.7%); women - 109 (39.3%). Patients aged 31-79 years (59.6±5.7) years. All patients were operated on radically with the resection of the invaded parts of the urinary tract en bloc. Both abdominal surgeons and urologists took part in the operation. The study proved that the invasion of the urinary tract by colorectal cancer should not become a reason for the surgery refusal. The subtotal resection of the urinary bladder by its cancer invasion demonstrated the appropriate radicalism and functional postoperative results. The efficacy of such combined operations was proved by the high level of social adaptation of the operated patients - 18 (51.4%) of 35 followed up patients came back to the previous level of social activity. Urinary tracts' resection did not influenced the level of postoperative lethality.

The purpose of this study is to report early complications in our initial experience with the holmium laser in 133 patients. A retrospective study of patients undergoing endourological procedures with the holmium laser was performed. Complications included urinary tract infection (3), post-operative bradycardia (1), inverted T-waves (1), intractable flank pain (1), urinary retention (1), inability to access a lower pole calyx with a 365 micron fiber (9), stone migration (5), termination of procedure due to poor visualization (2). No ureteral perforations or strictures occurred. The holmium laser was capable of fragmenting all urinary calculi in this study. In our initial experience, the holmium laser is safe and effective in the treatment of genitourinary pathology. Use of laser fibers larger than 200 microns occasionally limit deflection into a lower pole or dependent calyx.

We analysed the impact of predefined risk factors: age, diabetes, history of pelvic irradiation, prior surgery for stress urinary incontinence (SUI), prior urethral stricture, additional procedure during SUI surgery, duration of incontinence, ASA-classification and cause for incontinence on failure and complications in male SUI surgery. We retrospectively identified 506 patients with an artificial urinary sphincter (AUS) and 513 patients with a male sling (MS) in a multicenter cohort study. Complication rates were correlated to the risk factors in univariate analysis. Subsequently, a multivariate logistic regression adjusted to the risk factors was performed. A p value <0.05 was considered statistically significant. A history of pelvic irradiation was an independent risk factor for explantation in AUS (p < 0.001) and MS (p = 0.018). Moreover, prior urethral stricture (p = 0.036) and higher ASA-classification (p = 0.039) were positively correlated with explantation in univariate analysis for AUS. Urethral erosion was correlated with prior urethral stricture (p < 0.001) and a history of pelvic irradiation (p < 0.001) in AUS. Furthermore, infection was correlated with additional procedures during SUI surgery in univariate analysis (p = 0.037) in MS. We first identified the correlation of higher ASA-classification and explantation in AUS. Nevertheless, only a few novel risk factors had a significant influence on the failure of MS or AUS. © 2016 S. Karger AG, Basel.

Urinary tract infections constitute a large proportion of nosocomial infections, and the urinary catheter is the most important predisposing factor. Encrustation induced by urease-producing uropathogens like Proteus mirabilis causes further complications. In the present work, a strategy for controllable and sustained release of silver over several weeks has been developed for combating bacterial infection and encrustation in urinary devices. Silver nanoparticles (AgNPs) were first immobilized on polydopamine (PDA) pre-treated silicone catheter surface and this was followed by another PDA coating. The number of AgNP-PDA bilayers could be manipulated to control the amount of silver loaded and its subsequent release. Poly(sulfobetaine methacrylate-co-acrylamide) was then grafted to provide an antifouling outer layer, and to ensure free diffusion of Ag from the surface. The micron-scale combination of an antifouling coating with AgNP-PDA bilayers reduced colonization of the urinary catheter by uropathogens by approximately two orders of magnitude. With one and two AgNP-PDA bilayers, the coated catheter could resist encrustation for 12 and 45 days, respectively, compared with approximately 6 days with the Dover™ silver-coated catheter. Such anti-infective and anti-encrustation catheters can potentially have a large impact on reducing patient morbidity and healthcare expenditure. © 2014 Wiley Periodicals, Inc.

PURPOSE OF THE STUDY A very serious complication following joint replacement surgery is periprosthetic joint infection that can be caused by a urinary tract infection. Insertion of an indwelling urinary catheter constitutes a risk factor that may result in urinary tract infections. The aim of this prospective randomised study was to compare the occurrence of significant bacteriuria and symptomatic urinary tract infections during antibiotic prophylaxis at the time of removal of an indwelling urinary catheter by cotrimoxazole in two doses and with no administration of antibiotics. We also monitored the incidence of potential periprosthetic infection following the endoprosthesis implantation. The findings of preoperative urine tests were compared with the declared negative preoperative examination. MATERIAL AND METHODS The study included patients indicated for a total hip or knee replacement with a negative urine culture as a part of the preoperative testing. Where leukocyteria was detected, urine culture by mid-stream clean catch urine was obtained. The second part included patients, in whom an indwelling urinary catheter had to be inserted postoperatively for urine retention and/or monitoring of fluid balance and who were divided into two groups on a rota basis. No antibiotics were administered to the first group, whereas Cotrimoxazol 960 mg tablets p.o. was administered to the second group, 14 and 2 hours before the removal of the catheter. The urine culture test was performed 4 hours after the removal of the indwelling urinary catheter, in both the groups. The test was repeated after 14 days and a questionnaire was filled in to report urinary tract complications. Considered as significant bacteriuria by urinalysis was the laboratory finding of > 10x4 CFU/ml in case of a single pathogen or > 10x5 in case of multiple pathogens. The results were statistically processed by Fischer's exact test with the level of significance = 0.05. RESULTS In the first part of the study leukocyturia was detected by a test strip in 112 of the total of 478 patients. In 10 women, significant bacteriuria was found. Altogether 50 women and 50 men were randomly assigned to the second part of the study. The indwelling urinary catheter was in place for 4 days on average. In men, no statistically significant difference was detected in significant bacteriuria findings, in women a statistically significant difference of p = 0.00162 was found after the removal and after 14 days the borderline of statistical significance of p = 0.0507 was achieved, but no symptomatic urinary tract infection was present. In the period from 20 to 32 months following the total joint replacement, no periprosthetic infection caused by urinary tract infection was reported. DISCUSSION There is enough evidence to prove the correlation between the symptomatic urinary tract infection and periprosthetic infection. On the other hand, asymptomatic bacteriuria is a common finding in patients before the planned hip of knee joint replacement and its treatment is not recommended. No consensus has been achieved as yet regarding the method of antibiotic prophylaxis for an inserted urinary catheter. Antibiotics are administered throughout the period of catheterisation by an indwelling urinary catheter, during its removal, or are not administered at all. In our study antibiotics were administered during the removal of an indwelling urinary catheter and a statistically significant difference was found in women. It concerned, however, only a higher incidence of asymptomatic bacteriuria not treated by antibiotics, which in the next follow-up period did not lead to periprosthetic infection. CONCLUSIONS Despite the negative pre-operative urine culture, frequent incidence of leukocyturia and symptomatic urinary infections were detected in a fairly high number of cases. Therefore, we recommend asking the patients during the hospital admission process specifically about the urinary infection symptoms. The results of our study show that antibiotic prophylaxis during the removal of indwelling urinary catheters placed for a short-term is unnecessary. Key words: endoprosthesis, urinary catheter, bacteriuria, urinary tract infection.

Empirical fluoroquinolone therapy is widely used in treating complicated urinary tract infections (cUTIs), even in areas of high fluoroquinolone resistance. While it is believed that high antibiotic concentrations in urine might be sufficient to overcome and effectively treat infections caused by resistant bacteria, clinical trial data validating this assumption are limited. This post hoc analysis evaluated the efficacy of ceftolozane/tazobactam versus levofloxacin in the subgroup of patients with cUTIs caused by levofloxacin-resistant pathogens in a randomized, controlled trial (NCT01345929/NCT01345955). Hospitalized adults with cUTI/pyelonephritis were randomized to 7 days of 1.5 g of ceftolozane/tazobactam every 8 h or 750 mg of levofloxacin once daily, before availability of culture and susceptibility data. A composite of microbiological eradication and clinical cure 5 to 9 days post-therapy was assessed in the microbiological modified ITT (mMITT; n = 800) and microbiologically evaluable (ME; n = 694) populations. In the mMITT population, there were 212 patients (26.5%) with at least one baseline uropathogen that was resistant to levofloxacin. The majority of uropathogens in this subgroup were Enterobacteriaceae (n = 186) that were susceptible to ceftolozane/tazobactam [MIC ≤2 mg/L, 88.7% (165/186)]. Among patients with levofloxacin-resistant pathogens, ceftolozane/tazobactam demonstrated significantly higher composite cure rates than levofloxacin in both the mMITT [60.0% (60/100) versus 39.3% (44/112); 95% CI for the treatment difference, 7.2%-33.2%] and ME [64.0% (57/89) versus 43.4% (43/99); 95% CI for the treatment difference, 6.3%-33.7%] populations, respectively. High urinary levels of levofloxacin did not reliably cure cUTIs. Seven day treatment with ceftolozane/tazobactam was more effective than high-dose levofloxacin treatment in patients with cUTI caused by levofloxacin-resistant bacteria, and it may be an alternative treatment in settings of increased fluoroquinolone resistance. © The Author 2016.

To analyse the trends in the number of deaths attributable to urolithiasis in England and Wales over the past 15 years (1999-2013). Urolithiasis has an estimated lifetime risk of 12% in males and 6% in females and is not perceived as a life-threatening pathology. Admissions with urinary calculi contribute to 0.5% of all inpatient hospital stays, and the number of deaths attributable to stone disease has yet to be identified and presented. Office of National Statistics data relating to causes of death from urolithiasis, coded as International Classification of Diseases (ICD)-10 N20-N23, was collated and analysed for the 15-year period from 1999 to 2013 in England and Wales. These data were sub-categorised into anatomical location of calculi, age, and gender. In all, 1954 deaths were attributed to urolithiasis from 1999 to 2013 (mean 130.3 deaths/year). Of which, 141 were attributed to ureteric stones (mean 9.4 deaths/year). Calculi of the kidney and ureter accounted for 91% of all deaths secondary to urolithiasis; lower urinary tract (bladder or urethra) calculi contributed to only 7.9% of deaths. The data revealed an overall increasing trend in mortality from urolithiasis over this 15-year period, with an increase of 3.8 deaths/year based on a linear trend (R(2) = 0.65). Overall, the number of deaths in females was significantly higher than in males (ratio 1.5:1, P < 0.001); kidney and ureteric calculi causing death had a female preponderance (1.7:1, female:male); whereas calculi of the lower urinary tract was more common in males (1:2.2, female:male). Stone disease still causes death in the 21st century in England and Wales. This trend of increasing deaths must be placed in the context of the concurrent rising incidence of urolithiasis in the UK and the number of stone-related hospital episodes. The primary cause of death relating to complications of stone disease for each individual case should be further investigated to facilitate prevention of complications of urolithiasis. © 2016 The Authors BJU International © 2016 BJU International Published by John Wiley & Sons Ltd.

Common questions about the diagnosis and management of benign prostatic hyperplasia.

PubMed

Pearson, Ryan; Williams, Pamela M

2014-12-01

Benign prostatic hyperplasia (BPH) is a common condition that increases in prevalence with age. A history should include onset, duration, and severity of lower urinary tract symptoms and medication use to rule out other causes of symptoms. Physical examination includes a digital rectal examination and assessment for bladder distention or neurologic impairment. Recommended tests include serum prostate-specific antigen measurement and urinalysis to help identify infection, genitourinary cancer, or calculi as an alternative cause of lower urinary tract symptoms. BPH severity is assessed using validated, self-administered symptom questionnaires such as the American Urological Association Symptom Index or International Prostate Symptom Score. Mild or nonbothersome symptoms do not require treatment. Bothersome symptoms are managed with lifestyle modifications, medications, and surgery. Alpha blockers are first-line medications for BPH. Surgical referral is indicated if BPH-related complications develop, medical therapy fails, or the patient chooses it. Dietary supplements, such as saw palmetto, pygeum, cernilton, and beta sitosterols, and acupuncture are not recommended for the management of BPH.

Diabetes mellitus complicates 3-5% of all pregnancies and is a major cause of perinatal morbidity and mortality. The diet and insulin have revolutionized the care related with pregnancy complicated by diabetes mellitus. To report the management experience in patients with diabetes and pregnancy at the Instituto Materno Infantil, Estado de Mexico. A descriptive, retrospective, observational and cross-sectional study of pregnant women with diabetes and pregnancy was conducted from 2003 to 2004. We included 55 pregnant women who had: gestational diabetes 30 (54.4%), pregestational diabetes 24 (43.6%), and carbohydrate intolerance 1 (1.8%); every one of them were controlled either with diet, insulin or both. The mean age was 30.6, 80% with family history of type 2 diabetes mellitus, 9% gestational diabetes. Gestational diabetes was diagnosed in 33.3% by abnormal 50 g glucose screening and 46.6% with oral glucose tolerance test (OGTT). The main complications among the patients were urinary disease (61.3%) and the major fetal malformation were those related with cardiovascular disease (9.09%). The most frequent mode of delivery was cesarean section (58%) and birth weight was of 3,146 g. The main risk factors identified among women in the study group were as follow: More than 25 years of age and family history of diabetes mellitus. We observed a progressive increase in the insulin dosage. The most consistent complications among the patients were urinary infection and the major fetal malformation was cardiovascular disease.

Uropathogenic Escherichia coli (UPEC), a member of extraintestinal pathogenic E. coli, cause ∼80% of community-acquired urinary tract infections (UTI) in humans. UPEC initiates its colonization in epithelial cells lining the urinary tract with a complicated life cycle, replicating and persisting in intracellular and extracellular niches. Consequently, UPEC causes cystitis and more severe form of pyelonephritis. To further understand the virulence characteristics of UPEC, we investigated the roles of BarA-UvrY two-component system (TCS) in regulating UPEC virulence. Our results showed that mutation of BarA-UvrY TCS significantly decreased the virulence of UPEC CFT073, as assessed by mouse urinary tract infection, chicken embryo killing assay, and cytotoxicity assay on human kidney and uroepithelial cell lines. Furthermore, mutation of either barA or uvrY gene reduced the production of hemolysin, lipopolysaccharide (LPS), proinflammatory cytokines (TNF-α and IL-6) and chemokine (IL-8). The virulence phenotype was restored similar to that of wild-type by complementation of either barA or uvrY gene in trans. In addition, we discussed a possible link between the BarA-UvrY TCS and CsrA in positively and negatively controlling virulence in UPEC. Overall, this study provides the evidences for BarA-UvrY TCS regulates the virulence of UPEC CFT073 and may point to mechanisms by which virulence regulations are observed in different ways may control the long-term survival of UPEC in the urinary tract.

Objective To evaluate the risk of different in-hospital complications for patients undergoing a radical cystectomy (RC), as limited nationwide population data on short- and long-term complications after RC is available, despite it being the standard treatment for localised muscle-invasive urinary bladder cancer (UBC). Patients and Methods In all, 7608 persons underwent a RC after UBC diagnosis, as registered in the Swedish National Patient Register between 1964 and 2008. We estimated the frequency and incidences and calculated hazard ratios (HR) and 95% confidence intervals (CI) using multivariate Cox proportional hazards models. Results Urinary tract infection/septicaemia was the most common complication following radical cystectomy, with an incidence of 90.4 per 1,000 person years. There was a higher risk of urinary tract infection among patients who had a continent cutaneous reservoir (HR: 1.11 (0.94–1.30) or orthotopic neobladder 1.21 (1.05–1.39) than among those with ileal conduit. Similarly, continent cutaneous reservoir and orthotopic neobladder were associated with increased risks for wound and abdominal wall hernias, stones in the urinary tract, hydronephrosis and nephrostomy tube treatment, and kidney failure. In contrast, risk of bowel obstruction was lower among those with orthotopic neobladder than those with ileal conduit (HR: 0.64 (0.50–0.81)) and those with continent cutaneous reservoir (HR: 0.92 (0.73–1.16). Conclusions In-hospital complications after RC are numerous and continue to accumulate for many years after surgery, indicating the need for life-long follow-up of these patients. Comparison between different types of diversion should, however, be made with care because of potential confounding by indication. PMID:23906011

Urinary tract infection (UTI) is one of the most common bacterial infections, and the incidence in women is much higher than in men. The diagnosis of a UTI can be made based on a combination of symptoms and a positive urine analysis or culture. Most UTIs are uncomplicated UTIs, defined as cystitis in a woman who is not pregnant, is not immunocompromised, has no anatomical and functional abnormalities of the urogenital tract, and does not exhibit signs of tissue invasion and systemic infection. All UTIs that are not uncomplicated are considered to be complicated UTIs. Differentiation between uncomplicated and complicated UTIs has implications for therapy because the risks of complications or treatment failure are increased for patients with a complicated UTI. Asymptomatic bacteriuria (ASB) is defined as the presence of a positive urine culture collected from a patient without symptoms of a UTI. Concerning the complicated UTI, it is possible to make a differentiation between UTI with systemic symptoms (febrile UTI) and UTI in a host, which carries an increased risk to develop complications of this UTI. Febrile UTIs are urosepsis, pyelonephritis, and prostatitis. A complicated host is defined as one that has an increased risk for complications, to which the following groups belong: men, pregnant women, immunocompromised patients, or those who have an anatomical or functional abnormality of the urogenital tract (e.g., spinal cord-injury patients, renal stones, urinary catheter).

An in-situ infection detection sensor coating for urinary catheters

We describe a novel infection-responsive coating for urinary catheters that provides a clear visual early warning of Proteus mirabilis infection and subsequent blockage. The crystalline biofilms of P. mirabilis can cause serious complications for patients undergoing long-term bladder catheterisation. Healthy urine is around pH 6, bacterial urease increases urine pH leading to the precipitation of calcium and magnesium deposits from the urine, resulting in dense crystalline biofilms on the catheter surface that blocks urine flow. The coating is a dual layered system in which the lower poly(vinyl alcohol) layer contains the self-quenching dye carboxyfluorescein. This is capped by an upper layer of the pH responsive polymer poly(methyl methacrylate-co-methacrylic acid) (Eudragit S100®). Elevation of urinary pH (>pH 7) dissolves the Eudragit layer, releasing the dye to provide a clear visual warning of impending blockage. Evaluation of prototype coatings using a clinically relevant in vitro bladder model system demonstrated that coatings provide up to 12 h advanced warning of blockage, and are stable both in the absence of infection, and in the presence of species that do not cause catheter blockage. At the present time, there are no effective methods to control these infections or provide warning of impending catheter blockage. PMID:26945183

Stricture urethra, though a rare condition, still is a rational and troublesome problem in the international society. Major complications caused by this disease are obstructed urine flow, urine stasis leading to urinary tract infection, calculi formation, etc. This condition can be correlated with Mutramarga Sankocha in Ayurveda. Modern medical science suggests urethral dilatation, which may cause bleeding, false passage and fistula formation in few cases. Surgical procedures have their own complications and limitations. Uttarabasti, a para-surgical procedure is the most effective available treatment in Ayurveda for the diseases of Mutravaha Strotas. In the present study, total 60 patients of urethral stricture were divided into two groups and treated with Uttarabasti (Group A) and urethral dilatation (Group B). The symptoms like obstructed urine flow, straining, dribbling and prolongation of micturation were assessed before and after treatment. The results of the study were significant on all the parameters. PMID:24250127

Asymptomatic bacteriuria and symptomatic urinary tract infections during pregnancy.

PubMed

Macejko, Amanda M; Schaeffer, Anthony J

2007-02-01

Urinary tract infections are common complications of pregnancy; upper tract infections in particular may lead to significant morbidity for both the mother and fetus. Bacteriuria is a significant risk factor for developing pyelonephritis in pregnant women. Therefore, proper screening and treatment of bacteriuria during pregnancy is necessary to prevent complications. All women should be screened for bacteriuria in the first trimester, and women with a history of recurrent urinary tract infections or anomalies should have repeat bacteriuria screening throughout pregnancy. Treatment of bacteriuria should include 3-day therapy with appropriate antimicrobials, and women should be followed closely after treatment because recurrence may occur in up to one third of patients.

Uropathogenic Escherichia coli (UPEC) is a causative agent in the vast majority of urinary tract infections (UTIs), including cystitis and pyelonephritis, and infectious complications, which may result in acute renal failure in healthy individuals as well as in renal transplant patients. UPEC expresses a multitude of virulence factors to break the inertia of the mucosal barrier. In response to the breach by UPEC into the normally sterile urinary tract, host inflammatory responses are triggered leading to cytokine production, neutrophil influx, and the exfoliation of infected bladder epithelial cells. Several signaling pathways activated during UPEC infection, including the pathways known to activate the innate immune response, interact with calcium-dependent signaling pathways. Some UPEC isolates, however, might possess strategies to delay or suppress the activation of components of the innate host response in the urinary tract. Studies published in the recent past provide new information regarding how virulence factors of uropathogenic E. coli are involved in activation of the innate host response. Despite numerous host defense mechanisms, UPEC can persist within the urinary tract and may serve as a reservoir for recurrent infections and serious complications. Presentation of the molecular details of these events is essential for development of successful strategies for prevention of human UTIs and urological complications associated with UTIs.

Some authors sustained that the pessimistic thought of the Italian writer and philosopher Giacomo Leopardi (1798-1837) may be attributed to his unhappy life, characterized by several health problems. His philosophical theories appear as the result of depressive and melancholic state, related to his precarious health conditions, so limiting their intrinsic values. Several authors formulated various hypotheses on the diseases that Leopardi suffered from and postulated different theories on the cause of his early death. This article assumed that Leopardi may have been affected by juvenile ankylosing spondylitis, conditioning spinal deformities, relapsing-remitting uveitis, urinary tract and bowel tract problems, and acute arthritis. Chest deformity, as a complication of juvenile ankylosing spondylitis, may have caused progressive cardiorespiratory failure, worsened by recurrent bronchial and pulmonary complications, until his death caused by acute right ventricular heart failure. The acknowledgment of a physical cause of Leopardi's disease contributes to reevaluate his "cosmic pessimism" as an original expression of his thought, so leading a general revaluation of the figure of one of the most important European thinkers of the 19th century.

Legionella pneumophila serogroup 3 infection: importance of serology.

PubMed

Khanna, N; Meikle, A; Gillespie, L; Edwards, G; Lindsay, D

2012-08-01

We present a case of Legionella pneumophila serogroup 3 (LP3) infection in a patient with severe community-acquired pneumonia (CAP). The diagnosis was complicated by an initial equivocal L. pneumophila urinary antigen test, followed by two negative samples. LP3 was cultured from a sputum sample and the diagnosis was confirmed by serology 15 days into the admission. This case highlights the importance of considering non-LP1 serogroups as causes of CAP and the role of serological testing in diagnosis.

Cancer patients diagnosed with type 2 diabetes mellitus (T2DM) are at an increased risk of death due to cancer. However, whether T2DM comorbidity increases other causes of death in cancer patients is the novel theme of this study. Patients with T2DM were identified from the nationwide Swedish Hospital Discharge Register and linked with patients with cancer recorded from the Swedish Cancer Registry. Hazard ratios (HRs) were calculated for death due to all causes among cancer patients with and without T2DM; both underlying and multiple causes of death were examined using the Cox regression model. A total of 13 325 cancer patients were identified with comorbidity of T2DM. The total number of deaths of cancer patients was 276 021. Of these, 5900 occurred after T2DM diagnosis. For underlying causes of death, except for T2DM, the highest cause-specific HRs were found for complications of bacterial disease (HR, 3.93; 95% CI, 3.04-5.09), urinary system disease (HR, 3.39; 95% CI, 2.78-4.12), and myocardial infarction (HR, 2.93; 95% CI, 2.75-3.12). When risk of death was examined for both underlying and multiple causes of death, the highest HRs were found for hypertensive disease (HR, 3.42; 95% CI, 3.15-3.72), urinary system disease (HR, 3.39; 95% CI, 3.17-3.63), and arterial disease (HR, 3.26; 95% CI, 3.08-3.46). The diagnosis of T2DM in cancer patients is associated with an increased risk of death due to various causes, including myocardial infarction, other bacterial disease, urinary system disease, hypertensive disease, arterial disease, and so on, which may be related to both cancer and treatment. Clinicians that treat cancer patients with T2DM should pay more attention to comorbidities.

The mechanisms underlying progression of type 2 diabetes are complex and varied. Recent studies indicated that oxidative stress provided a new sight. To further assess the relationship between nucleic acid oxidation and complications in patients with type 2 diabetes and explore its possible molecular mechanisms, we studied 1316 subjects, including 633 type 2 diabetes patients and 683 age- and sex-matched healthy controls. Urinary levels of DNA oxidation marker 8-oxo-7,8-dihydro-2'-deoxyguanosine (8-oxodGuo) and RNA oxidation marker 8-oxo-7,8-dihydroguanosine (8-oxoGuo) were measured by ultraperformance liquid chromatography and mass spectrometry (UPLC-MS/MS). Serum glucose, HbA1c, total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides (TG) were also determined. The results showed significantly elevated levels of both the urinary 8-oxodGuo and 8-oxoGuo in diabetes patients with/without complications compared with age-matched healthy control subjects (p = 0.02 and p < 0.001, resp.). Patients with complications, especially macrovascular complications, exhibited higher levels of 8-oxoGuo than those without complications, while there was no difference in the concentrations of serum glucose and lipids. The finding indicates the role for oxidative damage to DNA and RNA, as a molecular mechanism contributing to the progression of type 2 diabetes. Elevated levels of 8-oxoGuo may be a risk factor for type 2 diabetes complications, especially in diabetic macrovascular complications.

Urological complications of coitus.

PubMed

Eke, N

2002-02-01

To ascertain the urological complications of coitus, as the proximity of the lower urinary tract to the organs of coitus exposes the tract to coital trauma. Medline was searched from 1966 to 2000 to identify reports on coital injuries. Publications and relevant references were retrieved. Those reporting urological complications were selected for analysis. In all, 1454 cases of reported coital injuries were reviewed; 790 occurred in men while 664 occurred in women, mainly in the genital area. Physical urological complications were more common in men than in women. The injuries were often sustained during voluntary coitus, but one penile fracture was sustained during an attempted rape. The presentations included penile swellings and deviations, haemorrhage, erectile dysfunction and urinary incontinence. Complications included vesicovaginal fistulae, bladder and cavernosal ruptures, and urinary tract infections. Rare complications included isolated rupture of the penile vasculature. Major risk factors included penovaginal disproportion, excessive force at coitus, urethral coitus, fellatio and anal intercourse. Urethral injuries were the commonest complications; in men these were associated with 10-38% of penile fractures. The treatments included cold compress and anti-inflammatory agents in contusions, repairs of lacerations, closure of fistulae and urethral and vaginal reconstruction. The results of treatment were essentially good. Recurrent penile fractures were reported. Coitus, although pleasurable, may be risky. The complications have been termed 'faux pas' implying that they are preventable. While the ultimate prevention is abstinence, this is an unrealistic prescription. Therefore, efforts are necessary to identify risk factors to enable preventive strategies.

2013-09-01

To evaluate, feasibility, efficacy and morbidity of laparoscopic artificial urinary sphincter (AUS) implantation in women with severe stress urinary incontinence. Twenty-six women with severe stress urinary incontinence were treated between October 2007 and January 2012 by laparoscopic implantation of an AUS AMS 800 (American medical Systems, Inc., Minnetonka, Minnesota). For 18 patients AUS was primary implanted and, for eight, AUS was revised for a mechanical failure. Three patients had a concomitant laparoscopic vaginal prolapse repair. Mean value was for age 64 years, BMI 27.8kg/m2, and mean maximal urethral closure pressure was 26.75cm of water. Most of the patients (88%) had a history of pelvic or incontinence surgery. The study was a retrospective analysis of operative parameters, complications and functional results. Three conversions in open surgery and five bladder injuries were described. Mean operative time was 149 minutes. Bladder catheter was removed at a mean of day 3.8. Mean post-operative stay was 5 days. Early postoperative complications consist in eight acute transient urinary retentions, two pump migrations, and one vaginal injury. Late post-operative complications consist in one vaginal erosion. Explantation of AUS was performed for these last two patients. Mean follow-up was 20 months. Sixteen patients are totally continent, five have a social continence (1 pad/day) and three need more than one pad/day. Our results compare favorably to literature either for laparoscopic or conventional approach with a limited learning curve. Laparoscopic implantation of AUS in women with severe stress urinary incontinence was feasible and efficient. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

Clinical Options for the Treatment of Urinary Tract Infections in Children

2014-01-01

Urinary Tract Infections (UTI) are a common cause of childhood febrile illness with 7% of girls and 2% of boys having a symptomatic culture positive UTI by the age of six years. Although there are conflicting views on the long term sequelae of UTI, as well as the place of prophylaxis, the universal aims of treatment of childhood UTI remain those of symptom alleviation, prevention of systemic infection and short and longer term complications. There is good evidence of historical and emerging resistance patterns, therefore rationalisation of prescription patterns by knowledge of sensitivities coupled with re-examination of empirical antibiotic choices is clearly important. Local formularies should reflect geographical resistance patterns along with best evidence on the duration and choice of antibiotic in order to maximize therapeutic effect, while minimizing the development of resistant strains.

2015-09-01

Thyrotoxic periodic paralysis (TPP) is characterized by the presence of muscle paralysis, hypokalemia, and hyperthyroidism. We report the case of a young man with paralysis of the lower extremities, severe hypokalemia, and concurrent hyperthyroidism. TPP was suspected; therefore, treatment consisting of judicious potassium (K+) repletion and β-blocker administration was initiated. However, urinary K+ excretion rate, as well as refractoriness to treatment, was inconsistent with TPP. Chronic alcoholism was considered as an alternative cause of hypokalemia, and serum K+ was restored through vigorous K repletion and the addition of K+ -sparing diuretics. The presence of thyrotoxicosis and hypokalemia does not always indicate a diagnosis of TPP. Exclusion of TPP can be accomplished by immediate evaluation of urinary K+ excretion, acid-base status, and the amount of potassium chloride required to correct hypokalemia at presentation.

To reduce complications of transobturator tension-free vaginal tape, single-incision devices were introduced in the last years. We here report a comparison between the tension-free vaginal tape-obturator (TVT-O) and the TVT-Secur techniques in terms of efficacy and safety. Eighty-four patients with stress urinary incontinence (SUI) were scheduled to undergo TVT-O or TVT-Secur. Duration of the procedure, subjective estimate of blood loss, intraoperative and postoperative complications, postoperative postvoidal residue (PVR), time to first voiding, and pain level were recorded. Urodynamic tests, PVR, Incontinence Questionnaire Short Form (ICIQ-SF), King's Health Questionnaire, and a urinary diary were performed before and 12 months after procedure. No differences in terms of cure rate were observed between the two groups (81.6% vs. 83.8%). Complication rate in the TVT-Secur group was lower (8.1%) than in the TVT-O group (15.8%), but not significant. Both techniques seem to be effective and safe, with a low incidence of complications in both groups.

Nephrotic syndrome is a chronic disease that may act as a risk for other major infection in skin, respiratory and urinary tract, while also increasingthe chance for other diseases, like peritonitis, meningitis, and cellulitis. Cellulitis is often caused by Streptococcus β-hemolytic, Staphylococcus aureus, and Escherichia coli. The clinical features of cellulitis marked with redness rash and well-defined borders, pain pressure and swelling. Hypoalbuminemia which occurs due to proteinuria occurred in this patient acts as a risk factor for cellulitis. It has been reported the case of cellulitis as one of the complications of the nephrotic syndrome in the pediatric patient. The treatment has been given to the patient such as antibiotics and supportive therapy and also planned albumin substitution.

The practice of antibiotic prophylaxis against recurrent urinary tract infection (UTI), with hospitalization reserved for severe or complicated cases, has led to changes in the nature and culprit uropathogens of community-acquired (CA), hospital-treated UTI. Characterization of subgroups that need special considerations is crucial. To elucidate the trends and characteristics of CA Pseudomonas UTI in hospitalized children; define the antibiotic susceptibility; determine the appropriateness of the empiric antibiotics used; compare to other causes of UTI in this population; and thereby define predictors for Pseudomonas UTI. A prospective clinical and laboratory study from 2001 through 2005. Children with P. aeruginosa UTI were characterized and compared with non-Pseudomonas UTI. Of 351 episodes of culture-proven CA UTI, 28 (8%) were caused by Pseudomonas, representing a 2.8-fold increase from our previous study. Pseudomonas UTI was more common in children > 5 years (p < 0.01), with urinary abnormalities (p < 0.01) and with previous antibiotic use in the previous month (p < 0.001). Pseudomonas UTI was often resistant to antibiotics usually recommended for empiric therapy; 25% was initially treated with inappropriate IV antibiotics (4.6% in the non-Pseudomonas group, p < 0.001) with 1.3 days longer IV antibiotics. On multivariate analysis, risk factors for Pseudomonas UTI were previous antibiotic therapy and underlying urinary pathology. Pseudomonas UTI seems to increase in CA, hospital-treated children and is often treated inappropriately according to current treatment protocols. Awareness of this trend and knowledge of the defined risk factors of Pseudomonas UTI might improve the empiric antibiotic therapy.

Hem-o-lok clip: a neglected cause of severe bladder neck contracture and consequent urinary incontinence after robot-assisted laparoscopic radical prostatectomy.

Hem-o-lok clips are widely used during robot-assisted and laparoscopic radical prostatectomy to control the lateral pedicles. There are a few reports of hem-o-lok clip migration into the bladder or vesico-urethral anastomosis and only four cases of hem-o-lok clip migration resulting into bladder neck contracture. Herein, we describe the first case, to our knowledge, of hem-o-lok clip migration leading to severe bladder neck contracture and subsequent stress urinary incontinence. A 62-year-old Caucasian man underwent robot-assisted laparoscopic radical prostatectomy for a T1c Gleason 8 prostate cancer. One month after surgery the patient was fully continent; however, three months later, he presented with acute urinary retention requiring suprapubic drainage. Urethroscopy showed a hem-o-lok clip strongly attached to the area between the vesico-urethral anastomosis and the urethral sphincter and a severe bladder neck contracture behind it. Following cold-knife urethral incision and clip removal, the bladder neck contracture was widely resected. At 3-month follow-up, the patient voided spontaneously with a peak flow rate of 9.5 ml/sec and absence of post-void residual urine, but leaked 240 ml urine at the 24-hour pad test. To date, at 1-year follow-up, his voiding situation remains unchanged. The present report provides further evidence for the risk of hem-o-lok clip migration causing bladder neck contracture, and is the first to demonstrate the potential of such complication to result into stress urinary incontinence.

As a result of endourological advances, biomaterials have become increasingly used within the urinary tract. This review article provides an update on the current status of urinary tract biomaterials, discussing issues of biocompatibility, biomaterials available for use, clinical applications and biomaterial related complications. Perspectives on future materials for use in the urinary tract are also provided. We performed a comprehensive search of the peer reviewed literature on all aspects of biomaterials in the urinary tract using PubMed and MEDLINE. All pertinent articles were reviewed in detail. Any potential biomaterial must undergo rigorous physical and biocompatibility testing prior to its commercialization and use in humans. There are currently many different bulk materials and coatings available for the manufacturing of biomaterials, although the ideal material has yet to be discovered. For use in the urinary tract, biomaterials may be formed into devices, including ureteral and urethral stents, urethral catheters and percutaneous nephrostomy tubes. Despite significant advances in basic science research involving biocompatibility issues and biofilm formation, infection and encrustation remain associated with the use of biomaterials in the urinary tract and, therefore, limit their long-term indwelling time. Prosthetic devices formed from biomaterials will continue to be an essential tool in the practicing urologist's armamentarium. Ongoing research is essential to optimize biocompatibility and decrease biomaterial related complications such as infection and encrustation within the urinary tract. Future advances include biodegradables, novel coatings and tissue engineering.

The management of urinary tract infection (UTI) in individuals with spinal cord injury (SCI) continues to be of concern, due to complications that can occur. An emerging concept that is a common underlying pathophysiological process is involved, wherein pathogens causing UTI have a role in inflammatory progression. We hypothesized that members of the commensal flora, such as lactobacilli, may counter this reaction through anti-inflammatory mediation. This was assessed in a pilot two-patient study in which probiotic Lactobacillus rhamnosus GR-1 and Lactobacillus reuteri were administered to one patient and placebo to another, both along with antibiotics to treat acute UTI. Urinary TNF-alpha was significantly downregulated (P = .015) in the patient who received the probiotic and who used intermittent catheterization compared with patient on placebo and using an indwelling catheter. The extent to which this alteration resulted in improved well-being in spinal cord injured patients remains to be determined in a larger study.

CASE DESCRIPTION A 3-year-old male Cocker Spaniel renal transplant recipient was readmitted 39 weeks after transplantation because of acute clinical signs of pollakiuria, intermittent vomiting, decreased appetite, lethargy, and mild fever. CLINICAL FINDINGS Hydronephrosis and hydroureter were observed with ultrasonography and contrast cystography, and a diagnosis of vesicoureteral reflux (VUR) was made. Urinary tract infection (UTI) caused by Escherichia coli was also diagnosed on the basis of results of urine culture. TREATMENT AND OUTCOME Despite treatment of the UTI with an appropriate antimicrobial for 6 weeks, the VUR persisted and the UTI recurred 9 weeks after cessation of antimicrobial treatment. Therefore, surgical correction by means of revision extravesicular ureteroneocytostomy was performed. Both VUR and hydronephrosis resolved after surgery. No recurrences of clinical signs of urinary tract complications were observed during the subsequent 22-month follow-up period. CLINICAL RELEVANCE Results suggested that ureteral reimplantation with an extravesicular technique incorporating a long submucosal tunnel may be an effective treatment for VUR when medical management fails in canine renal transplant recipients with recurrent UTIs.

Kidney transplant is the treatment of choice for end-stage renal disease, but it is not without complications. We review the medical cause of significant renal impairment and complications that developed after kidney transplant in pediatric patients who required hospital admission and intervention and/or who were followed between 2007 and 2016. A retrospective noninterventional chart review study was conducted in pediatric patients who received a kidney transplant and/or followed at the nephrology clinic at Queen Rania Abdulla Children's Hospital between 2007 and 2016. In this study, 101 pediatric patients received a total of 103 transplants. Forty-eight patients (47%) experienced deterioration of kidney function out of a total of 53 episodes of complications; 37 of these episodes occurred early (0-6 mo after transplant), and 26 episodes occurred late. The causes of kidney function deterioration were surgical complications, acute tubular necrosis, cell- or antibody-mediated rejection, diabetes mellitus, urinary leak, recurrence of original disease, and chronic allograft nephropathy. Thirteen patients experienced graft loss; 50% of these losses were secondary to noncompliance to immunosuppressant medication treatment after transplant. A total of six patients died; 2 (23%) of these deaths occurred in the first week after transplant, whereas the other 4 patients died over a period of 10 years. Pediatric kidney transplant is not without complications; however, most of these complications are treatable and reversible. The most serious complications leading to graft loss and death occur early, in the first week after transplant. Improving immunosuppressant compliance after transplant would prevent 50% of graft losses.

Background: In this study, we attempt to identify the most appropriate catheter (silicone vs. latex) for short-term urinary catheterization. We compared the post-operative clinico-pathological complications between latex and silicone for short term catheterization in rabbits with hypospadias. Materials and Methods: Forty rabbits were used in our study to compare complications of catheterization. They were divided in two groups. Hypospadias like defect was created by a 1 cm long excision of the ventral urethra. For urethroplasty, we used tubularized incised plate technique. Latex and silicon catheters were used in groups 1 and 2, respectively. Post-operatively, routine laboratory urine test and complications (allergy, infection, bleeding) were compared in groups. Results: A total of 40 rabbits underwent hypospadias repair. Findings showed that there were no significant differences between groups based on urine test indices (P = NS). Urinary tract infection rate was 10% (2 rabbits) in latex and 0% in silicone groups (P = NS). There were no significant differences between groups regarding of cystitis grades between study groups (P = NS). Conclusion: It seems that urinary tract catheterization with latex catheters is a safe, feasible, and in-expensive procedure for short-term post-operative course in hypospadias surgery in patients without latex hypersensitivity.

Objectives To determine risk factors for and long-term effects of glycemic control on urinary incontinence among women with type 1 diabetes enrolled in the Epidemiology of Diabetes Interventions and Complications (EDIC) study. Methods The Diabetes Control and Complications Trial (1982 to 1993) cohort follow-up, EDIC, began in 1994. In 2004, women participants (N=550), completed a self-administered questionnaire on incontinence. Our primary outcome was ≥ weekly incontinence, overall and by type. Multivariable regression models were used to determine independent predictors of weekly UI, both overall and by type. Results Overall, 38% of women reported any incontinence and 17% reported ≥ weekly incontinence. Increasing body mass index (Odds Ratio (OR) 1.1 per kg/m2, 95% Confidence Interval (CI) 1.1−1.2) was significantly associated with weekly incontinence, overall and by type. Advancing age and two or more urinary tract infections in the prior year were associated with weekly urge incontinence (OR 1.4, 95% CI 1.0−2.0 per 5 years; OR 4.9, 95% CI 1.8−13.5, respectively). There was weaker evidence for increased risk with age for overall weekly incontinence (22% per 5 years, p=0.06) and stress incontinence (21 % per 5 years, p=0.08) Conclusions Urinary incontinence is common among women with type 1 diabetes and risk factors including advancing age, increased weight, and prior urinary tract infection are important. Weight reduction and treatment of urinary tract infections may have the additional benefit of preventing incontinence or reducing its severity. PMID:19362350

We examined the relationship between glycemic control and urinary tract infections in women with type 1 diabetes mellitus. Women enrolled in the Epidemiology of Diabetes Interventions and Complications study, the observational followup of the Diabetes Control and Complications Trial, were surveyed to assess the rate of physician diagnosed urinary tract infections in the preceding 12 months. The relationship between glycated hemoglobin levels and number of urinary tract infections in the previous 12 months was assessed using a multivariable Poisson regression model. A total of 572 women were evaluated at year 17. Mean age was 50.7 ± 7.2 years, mean body mass index was 28.6 ± 5.9 kg/m(2), mean type 1 diabetes duration was 29.8 ± 5.0 years and mean glycated hemoglobin was 8.0% ± 0.9%. Of these women 86 (15.0%) reported at least 1 physician diagnosed urinary tract infection during the last 12 months. Higher glycated hemoglobin levels were significantly associated with number of urinary tract infections such that for every unit increase (1%) in recent glycated hemoglobin level, there was a 21% (p=0.02) increase in urinary tract infection frequency in the previous 12 months after adjusting for race, hysterectomy status, urinary incontinence, sexual activity in the last 12 months, peripheral and autonomic neuropathy, and nephropathy. The frequency of urinary tract infections increases with poor glycemic control in women with type 1 diabetes. This relationship is independent of other well described predictors of urinary tract infections and suggests that factors directly related to glycemic control may influence the risk of lower urinary tract infections.

Bladder stones account for 5% of all urinary stone disease and can develop on a foreign body, such as a misplaced suture, eroded surgical mesh, or ureteral stent. In this case study, the authors present a patient with bladder stones associated with pubic hairs introduced during a monthly indwelling Foley catheter change. Clinicians have an important role in instructing patients on the use of proper technique and hygiene practices during urethral catheterization to minimize the potential for urinary complications.

We describe a novel infection-responsive coating for urinary catheters that provides a clear visual early warning of Proteus mirabilis infection and subsequent blockage. The crystalline biofilms of P. mirabilis can cause serious complications for patients undergoing long-term bladder catheterisation. Healthy urine is around pH 6, bacterial urease increases urine pH leading to the precipitation of calcium and magnesium deposits from the urine, resulting in dense crystalline biofilms on the catheter surface that blocks urine flow. The coating is a dual layered system in which the lower poly(vinyl alcohol) layer contains the self-quenching dye carboxyfluorescein. This is capped by an upper layer of the pH responsive polymer poly(methyl methacrylate-co-methacrylic acid) (Eudragit S100®). Elevation of urinary pH (>pH 7) dissolves the Eudragit layer, releasing the dye to provide a clear visual warning of impending blockage. Evaluation of prototype coatings using a clinically relevant in vitro bladder model system demonstrated that coatings provide up to 12h advanced warning of blockage, and are stable both in the absence of infection, and in the presence of species that do not cause catheter blockage. At the present time, there are no effective methods to control these infections or provide warning of impending catheter blockage. Copyright © 2016 The Authors. Published by Elsevier B.V.

Increased life expectancy have an effect on the rising percentage of elderly population in Indonesia and health problem associated with the elderly, particularly immobilization. Immobilization may cause various complications, especially when it has been overlooked without any appropriate and proper medical care in keeping with the procedures. High incidence of immobilization in elderly and the life-threatening complication call for an agreement on management of immobilization and its complication. Management of immobilization needs interdisciplinary team-work cooperation, the patients and their family. The management may be commenced through a complete geriatric review, formulating functional goals and constructing therapeutic plan. Various medical conditions and external factors that may act as risk factors of immobilization as well as drugs intake that may exaggerate the immobilization should be evaluated and optimally managed. Any complication due to immobilization and other concomitant disease/condition should be recognized and managed comprehensively in order to reduce morbidity and mortality. Management of immobilization and its complications include pharmacological and non-pharmacological treatment, i.e. various mobility exercises, utilization of ambulatory device and supporting appliance for assisting patients in stand-up position, as well as the management of urinary voiding and defecation.

Urinary tract infections and Candida albicans.

Urinary tract candidiasis is known as the most frequent nosocomial fungal infection worldwide. Candida albicans is the most common cause of nosocomial fungal urinary tract infections; however, a rapid change in the distribution of Candida species is undergoing. Simultaneously, the increase of urinary tract candidiasis has led to the appearance of antifungal resistant Candida species. In this review, we have an in depth look into Candida albicans uropathogenesis and distribution of the three most frequent Candida species contributing to urinary tract candidiasis in different countries around the world. For writing this review, Google Scholar -a scholarly search engine- (http://scholar.google.com/) and PubMed database (http://www.ncbi.nlm.nih.gov/pubmed/) were used. The most recently published original articles and reviews of literature relating to the first three Candida species causing urinary tract infections in different countries and the pathogenicity of Candida albicans were selected and studied. Although some studies show rapid changes in the uropathogenesis of Candida species causing urinary tract infections in some countries, Candida albicans is still the most important cause of candidal urinary tract infections. Despite the ranking of Candida albicans as the dominant species for urinary tract candidiasis, specific changes have occurred in some countries. At this time, it is important to continue the surveillance related to Candida species causing urinary tract infections to prevent, control and treat urinary tract candidiasis in future.

Urinary Tract Infections and Asymptomatic Bacteriuria in Renal Transplant Recipients

Asymptomatic bacteriuria and urinary tract infection are common complications after kidney transplantation. In this population, if urinary tract infection occurred in the first six months post procedure, it carries a grave impact on both graft and patient survival. Renal transplant recipients with urinary tract infection are often clinically asymptomatic as a consequence of immunosuppression. Urinary tract infection, however, may progress to acute pyelonephritis, bacteremia and the full blown picture of urosepsis. PubMed and Cochrane databases were searched. The purpose of this review is to discuss the screening and treatment of urinary tract infection and asymptomatic bacteriuria in renal transplant recipients and to evaluate the guidelines on the basis of a review of published evidence.

Mucopolysaccharidosis type II (MPS II) is caused by deficiency of lysosomal enzyme iduronate-2-sulfatase. Insufficient activity of the enzyme results in accumulation of glycosaminoglycans leading to progressive multisystem pathologies. MPS II is less likely to be complicated by kidney and urinary tract problems. We report a boy with MPS II, who developed left hydronephrosis. His hydronephrosis improved after starting enzyme replacement therapy. It was suggested that MPS II was closely associated with the pathogenesis of hydronephrosis. Copyright © 2016 Elsevier Inc.

Walsh, Colin A

2011-09-01

• Synthetic mid-urethral slings (MUSs) are considered the first choice surgical procedure for stress urinary incontinence. Recent publications have raised concerns about the efficacy of third generation single-incision mini-slings. The present paper is a systematic review of studies reporting 12-month outcomes after the TVT-Secur (TVT-S) procedure. • Pubmed/Medline online databases, abstracts from recent International Continence Society and International Urogynecological Association annual scientific meetings and the Clinicaltrials.gov and Controlled-trials.com online trial registries were searched for English-language articles containing the terms 'TVT-Secur', 'TVT Secur' or 'mini-sling'. The primary outcomes were objective and subjective cure rates at 12 months. Secondary outcomes included peri-operative (vaginal perforation, urinary retention, urinary tract infection [UTI]) and postoperative (mesh exposure, de novo overactive bladder (OAB), dyspareunia and return to theatre) complication rates. • Among 1178 women undergoing the TVT-S procedure, from 10 studies, both objective and subjective cure rate at 12 months was 76%, with objective cure significantly higher in women undergoing the 'U-type' approach. Vaginal perforation was a complication in 1.5% of cases, with a 2.4% incidence of mesh exposure in the first year. The incidence of de novo OAB symptoms was 10%. Rates of urinary retention (2.3%), UTI (4.4%), dyspareunia (1%) and return to theatre for complications (0.8%) were low. In the first year after a TVT-S procedure 5% of women required repeat continence surgery. • Longer-term studies and randomized comparisons with more established MUSs are required before TVT-S should be routinely used in the surgical treatment of stress urinary incontinence. © 2011 THE AUTHOR.

Biofilms of the Gram-negative bacterium Pseudomonas aeruginosa are one of the major causes of complicated urinary tract infections with detrimental outcome. To develop novel therapeutic strategies the molecular adaption strategies of P. aeruginosa biofilms to the conditions of the urinary tract were investigated thoroughly at the systems level using transcriptome, proteome, metabolome and enzyme activity analyses. For this purpose biofilms were grown anaerobically in artificial urine medium (AUM). Obtained data were integrated bioinformatically into gene regulatory and metabolic networks. The dominating response at the transcriptome and proteome level was the adaptation to iron limitation via the broad Fur regulon including 19 sigma factors and up to 80 regulated target genes or operons. In agreement, reduction of the iron cofactor-dependent nitrate respiratory metabolism was detected. An adaptation of the central metabolism to lactate, citrate and amino acid as carbon sources with the induction of the glyoxylate bypass was observed, while other components of AUM like urea and creatinine were not used. Amino acid utilization pathways were found induced, while fatty acid biosynthesis was reduced. The high amounts of phosphate found in AUM explain the reduction of phosphate assimilation systems. Increased quorum sensing activity with the parallel reduction of chemotaxis and flagellum assembly underscored the importance of the biofilm life style. However, reduced formation of the extracellular polysaccharide alginate, typical for P. aeruginosa biofilms in lungs, indicated a different biofilm type for urinary tract infections. Furthermore, the obtained quorum sensing response results in an increased production of virulence factors like the extracellular lipase LipA and protease LasB and AprA explaining the harmful cause of these infections.

Chronic kidney disease (CKD) is a common complication after liver transplantation. Kidney biopsies cannot be easily performed before liver transplantation to predict patients at high risk for CKD. The aim of our study was to determine whether pre-, peri- and post-transplant factors, as well as peptides present in preliver transplant urine samples were associated with loss in kidney function at 6 months post-transplantation using proteome analysis. Eighty patients who underwent a liver transplantation and that had pretransplant glomerular filtration rate (GFR) value of ≥60 mL/min/1.73 m² (MDRD) were included in the study. GFR decreased significantly after transplantation. At month 6 post-transplantation, 40 patients displayed a CKD, i.e. eGFR of <60 mL/min/1.73 m², while the other 40 patients did not. Although thousands of peptides were identified, none was significantly associated with the development of CKD at 6 months after liver transplantation. Moreover, using a urinary peptidome classifier to detect preexisting CKD, no difference was found in CKD scores between the 2 groups. After analysis of a large number of pre-, peri- and post-transplant parameters, viral hepatitis as a cause for liver transplantation was the sole independent predictive factor for CKD. No difference in peptides with differential urinary abundance between patients who received a graft for virus related liver disease vs. all other causes of liver disease was observed. Urinary peptidome analysis before liver transplantation failed to identify a peptide pattern associated with the development of CKD at 6 months after liver transplantation. © 2014 John Wiley & Sons A/S.

Müller, J; Sulmoni, M

1992-01-01

Suprapubic Cystofix-cystostomy is a valuable alternative to the Foley-catheter. The advantages of suprapubic cystostomy are mainly a reduction of urinary tract infections, inflammatory reactions in the lower urinary tract and avoidance of late urethral strictures after transurethral catheterism. There are a few contraindications to be considered, mainly an empty bladder and coagulation disorders. The complication rate of suprapubic Cystofix-cystostomy, usually gross haematuria, is very low. Cystofix-cystostomy is as useful for short term urinary drainage as for long term drainage in the case of chronic voiding disorders.

Endometriosis is a benign pathology that affects 3% of the general population and about 10% of women of reproductive age. Three anatomoclinical entities are described: peritoneal, ovarian (endometrioma) and deep endometriosis characterized by the infiltration of anatomical structures or organs beyond the peritoneum. Laparoscopic surgery should be performed, as this is associated with a reduction in postoperative complications, length of hospitalization and convalescence. Several surgical techniques allow the removal of deep endometriosis with colorectal involvement: rectal shaving, anterior discoid resection, segmental resection. Deep endometriosis surgery with colorectal involvement is a source of postoperative complications: anastomotic fistula, rectovaginal fistula, intestinal occlusion, digestive haemorrhage, urinary fistula, deep pelvic abscess. Involvement of the urinary tract by endometriosis affects approximately 1% of patients with endometriosis. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

The purpose of bladder augmentation using the gastrointestinal tract is to create a low-pressure and high-capacity reservoir, permitting suitable continence and voiding, preserving the upper urinary tract. To analyze the indications, complications and results of our series of augmentation enterocystoplasties. We retrospectively reviewed patients undergoing augmentation enterocystoplasty in our department between 1997 and 2010, both included. The indications were: Interstitial cystitis, neurogenic bladder and inflammatory bladder retraction. In all cases a cystography, urethrocystoscopy, urodynamic study and studies of each condition. Bladder release is performed by means of medial laparotomy and an extraperitoneal approach with bivalve opening to the urethral orifices. The bladder augmentation is performed with a 15-20 cm segment of detubularized ileum obtained at 20 cm from the ileocecal valve; in cases of kidney failure, a 7-cm gastric body wedge is added. The bladder catheter was removed following cystogram after 15 days. Monitoring was performed by means of ultrasound with postvoid residual, blood analyses, urine culture and voiding diary. We performed a descriptive study of the demographic characteristics, postoperative complications according to the Clavien classification and in the long term. We included 24 patients, 19 women and 5 men with a mean age of 48.5 years and a median of 47 (21-77). Mean follow up was 7.5 years with a median of 8 (1-11). The indications were: 7 interstitial cystitis, 8 bladder retraction and 7 neurogenic bladder. There were no intraoperative complications. The postoperative complications were 3 Clavien I, 2 type II, 2 IIIA and 1 IIIB. In the long term, 3 patients presented urinary incontinence, 2 mild metabolic acidosis, 5 required self-catheterization, 6 bladder stones, 2 febrile urinary tract infections and 1 stricture of the anastomotic mouth. In three cases, an ileogastrocystoplasty was performed without hydroelectrolytic impairment or impairment of kidney function. In selected patients, augmentation enterocystoplasty constitutes an efficacious therapeutic option in the treatment of lower urinary tract dysfunction with scant morbidity and few complications.

The prevalence of urinary tract infection in children with severe acute malnutrition: a narrative review

PubMed Central

Uwaezuoke, Samuel N

2016-01-01

This article aims to review the current evidence which shows that the prevalence of urinary tract infection (UTI) has been increasing in children with severe acute malnutrition (SAM). UTI remains one of the most common causes of febrile illness in pediatric practice. Most studies conducted among hospitalized children with complicated SAM have reported high prevalence rates of UTI. Clearly, the knowledge of baseline risk of UTI can help clinicians to make informed diagnostic and therapeutic decisions in these children. From the global reports reviewed in this article, UTI prevalence rates range from as low as 6% to as high as 37% in developing countries, while the most common bacterial isolates from urine cultures are Gram-negative coliform organisms such as Escherichia coli and Klebsiella species. These findings form the basis for the current diagnostic and therapeutic guidelines for clinicians managing children with complicated SAM. With the reported high prevalence of UTI among these children and concerns over antibiotic resistance, more extensive data are required using standardized microbiological methods. Thus, the assessment of the performance of urine dipsticks and microscopy against the gold standard urine culture is an important step toward strengthening the evidence for the therapeutic guidelines for UTI in children with SAM.

We examined ghrelin, leptin and insulin in maternal blood during normal pregnancy and pregnancy complicated by urinary tract infection (UTI), as well as in cord blood at labor. A total of 36 delivering women with history of UTI during the third trimester of pregnancy were enrolled in the study; 12 healthy pregnant women served as a control. Infection markers (CRP and procalcitonin) were determined in maternal blood during the course of UTI and at labor. Ghrelin, leptin and insulin were determined during labor in venous maternal and in umbilical cord blood. We found negative correlation between infection markers in maternal blood during UTI, and level of tested hormones in cord blood, indicating potential risk of placental impairment due to energetic imbalance. We noted lower level of leptin in mothers with UTI and no change in leptin from umbilical blood comparing subjects with and without UTI. Low level of ghrelin was observed in maternal and cord blood when pregnancy was complicated by UTI. Insulin concentrations were high in mothers with UTI and low in their newborn's cord blood. Increased maternal insulin level could indicate peripheral insulin resistance caused by the infection. UTI during pregnancy affects the concentration of hormones responsible for regulating energetic homeostasis within the placenta.

Trichobezoar is a rare condition whereby a hairball is found in the human stomach or gastrointestinal tract, most frequently in young women, mainly in association with a psychiatric disorder. Trichobezoar cases have also been reported in the bladder and represent a rare complication of foreign bodies, called "hair nidus or hair ball," in patients with chronic catheter. Approximately 10% to 15% of patients on long-term urethral catheter or clean intermittent self-catheterization develop urinary tract stones. In a small minority of cases, bladder stones can develop around a foreign body that was introduced into the bladder. In the literature, there are few cases of foreign bladder bodies that formed stones over a hair nidus. Recognizing this condition can optimize the patient's quality of life. Herein, we present a case of a 71-year-old Caucasian male with a long-term catheter in hypocontractile urinary bladder secondary to injury of pelvic plexus after rectal surgery. He had a bladder stone caused by hair encrusted together. Hair is introduced into the bladder either by adherence to the catheter directly or by overlying the urethral meatus and being pushed internally. Regular hygiene and shaving of pubic area represent effective preventive measures to reduce this kind of complications in patients with chronic indwelling catheter or under a self-catheterization regimen.

ABSTRACT Cefiderocol, a novel parenteral siderophore cephalosporin, exhibits potent efficacy against most Gram-negative bacteria, including carbapenem-resistant strains. The aim of this study was to perform a population pharmacokinetic (PK) analysis based on plasma cefiderocol concentrations in healthy subjects, subjects with various degrees of renal function, and patients with complicated urinary tract infection (cUTI) or acute uncomplicated pyelonephritis (AUP) caused by Gram-negative pathogens and to calculate the fraction of the time during the dosing interval where the free drug concentration in plasma exceeds the MIC (fTMIC). Population PK models were developed with three renal function markers, body surface area-adjusted estimated glomerular filtration rate (eGFR), absolute eGFR, and creatinine clearance, on the basis of 2,571 plasma concentrations from 91 subjects without infection and 238 patients with infection. The population PK models with each renal function marker adequately described the plasma cefiderocol concentrations. Clear relationships of total clearance (CL) to all renal function markers were observed. Body weight and disease status (with or without infection) were also significant covariates. The CL in patients with infection was 26% higher than that in subjects without infection. The fTMIC values were more than 75% in all patients (and were 100% in most patients), suggesting that a sufficient exposure to cefiderocol was provided by the tested dose regimens (2 g every 8 h as the standard dose regimen) for the treatment of cUTI or AUP caused by Gram-negative pathogens.

Treatment of complicated urinary-tract infections is challenging due to rising antimicrobial resistance. We assessed the efficacy and safety of ceftolozane-tazobactam, a novel antibacterial with Gram-negative activity, in the treatment of patients with complicated lower-urinary-tract infections or pyelonephritis. ASPECT-cUTI was a randomised, double-blind, double-dummy, non-inferiority trial done in 209 centres in 25 countries. Between July, 2011, and September, 2013, hospital inpatients aged 18 years or older who had pyuria and a diagnosis of a complicated lower-urinary-tract infection or pyelonephritis were randomly assigned in a 1:1 ratio to receive intravenous 1·5 g ceftolozane-tazobactam every 8 h or intravenous high-dose (750 mg) levofloxacin once daily for 7 days. The randomisation schedule was computer generated in blocks of four and stratified by study site. The next allocation was obtained by the study site pharmacist via an interactive voice-response system. The primary endpoint was a composite of microbiological eradication and clinical cure 5-9 days after treatment in the microbiological modified intention-to-treat (MITT) population, with a non-inferiority margin of 10%. This study is registered with ClinicalTrials.gov, numbers NCT01345929 and NCT01345955. Of 1083 patients enrolled, 800 (73·9%), of whom 656 (82·0%) had pyelonephritis, were included in the microbiological MITT population. Ceftolozane-tazobactam was non-inferior to levofloxacin for composite cure (306 [76·9%] of 398 vs 275 [68·4%] of 402, 95% CI 2·3-14·6) and, as the lower bound of the two-sided 95% CI around the treatment difference was positive and greater than zero, superiority was indicated. Adverse event profiles were similar in the two treatment groups and were mainly non-serious. Treatment with ceftolozane-tazobactam led to better responses than high-dose levofloxacin in patients with complicated lower-urinary-tract infections or pyelonephritis. Cubist Pharmaceuticals.

The most common etiologic agent of this type of bacterial infections, involving the upper and lower urinary tract, are E. coli strains representing approximately 80% of cases. Uropathogenic E. coli strains produce several urovirulence factors which can be divided into two main types, surface virulence factors and exported virulence factors. Surface-exposed structures include mainly extracellular adhesive organelles such as fimbriae/pili necessary in adhesion, invasion, biofilm formation and cytokine induction. Among the surface-exposed polymeric adhesive structures there are three most invasive groups, type 1 pili, type P pili and Dr family of adhesins which are bioassembled via the conserved, among Gram-negative bacteria, chaperone-usher secretion system. Type 1 and P-piliated E. coli cause cystitis and pyelonephritis. The Dr family of adhesins recognizing DAF receptor is responsible for cystitis, pyelonephritis (especially in pregnant women) and diarrhoea (in infants). In addition, Dr-positive E. coli strains carry the risk of recurrent urinary tract infections. Pyelonephritis in pregnant women leads to a series of complications such as bacteremia, urosepsis, acute respiratory distress syndrome and even death. In the era of increasing drug resistance of bacteria, the development of vaccines, drugs termed pilicides and inhibitors of adhesion may be a promising tool in the fight against urogenital infections.

Diabetic nephropathy (DN) is one of the major complications of diabetes mellitus (DM), leads to chronic kidney disease (CKD), and, ultimately, is the main cause for end-stage kidney disease (ESKD). Beyond urinary albumin, no reliable biomarkers are available for accurate early diagnostics. Urinary extracellular vesicles (UEVs) have recently emerged as an interesting source of diagnostic and prognostic disease biomarkers. Here we used a protease and respective protease inhibitor array to profile urines of type 1 diabetes patients at different stages of kidney involvement. Urine samples were divided into groups based on the level of albuminuria and UEVs isolated by hydrostatic dialysis and screened for relative changes of 34 different proteases and 32 protease inhibitors, respectively. Interestingly, myeloblastin and its natural inhibitor elafin showed an increase in the normo- and microalbuminuric groups. Similarly, a characteristic pattern was observed in the array of protease inhibitors, with a marked increase of cystatin B, natural inhibitor of cathepsins L, H, and B as well as of neutrophil gelatinase-associated Lipocalin (NGAL) in the normoalbuminuric group. This study shows for the first time the distinctive alterations in comprehensive protease profiles of UEVs in diabetic nephropathy and uncovers intriguing mechanistic, prognostic, and diagnostic features of kidney damage in diabetes.

To assess virulence properties in uropathogenic Escherichia coli isolates from men with symptomatic urinary tract infection (UTI), we analyzed 88 urinary isolates from men with acute pyelonephritis (n = 41), febrile UTI without clinical signs of renal infection (n = 33), or acute cystitis (n = 14) for O:K:H serotype, P fimbriae, and production of hemolysin and aerobactin. In the three diagnostic groups, 88%, 67%, and 79% of the strains, respectively, were represented by 10 O antigen groups commonly associated with acute pyelonephritis in women and children. Fifty-eight different O:K:H serotypes could be identified, of which O18ac:K5:H- predominated (n = 8). There was a higher frequency of hemolytic strains among patients with pyelonephritis (73%) and febrile UTI (76%) and a lower frequency of P-fimbriated strains (56% and 45%, respectively) and aerobactin-positive strains (51% and 39%, respectively) among these patients than was previously encountered in women and children with uncomplicated acute pyelonephritis. The distribution of bacterial properties was unrelated to patient age and underlying complicating factors. The findings suggest differences in host-parasite relationships between men and women with symptomatic UTI caused by E. coli.

Escherichia coli is the most common pathogen causing Urinary Tract Infections (UTI). Data from the current National Surveillance program in Denmark (DANMAP) may not accurately represent the prevalence of resistant E. coli in primary care, because only urine samples from complicated cases may be forwarded to the microbiological departments at hospitals for diagnostic examination. The aim of this study was to assess the prevalence of resistant E. coli to the most commonly used antimicrobial agents in primary care in a consecutive sample of patients from general practice. Observational study carried out from December 2014 to December 2015. Thirty-nine general practices from The Capital Region of Denmark included adult patients with urinary tract symptoms and suspected UTI. All urine samples were sent to the central laboratory Statens Serum Institut (SSI). Significant bacteriuria was interpreted according to the European Urinalysis Standards. Susceptibility testing was performed and interpreted according to the European Committee on Antimicrobial Susceptibility Testing (EUCAST) standards. From the 39 general practices 505 patients were recruited. Completed data were obtained from 485 (96%) patients. According to the European Urinalysis Standards, 261 (54%) patients had positive bacteriuria. The most common uropathogen in patients with uncomplicated (uUTI) and complicated (cUTI) urinary tract infection was E. coli 105 (69%) and 76 (70%), respectively. Eighty-two (45%) of 181 E. coli isolates were resistant to at least one of the tested antibiotics and 50 out of 82 isolates were resistant to two or more antimicrobial agents. The highest resistance-rate was found against ampicillin 34% (95% CI 24;42) in uUTI and 36% (24;46) in cUTI. There were no differences in the distribution of resistance between uncomplicated and complicated cases. The prevalence of resistance was similar to the one reported in DANMAP 2014. In E. coli from uUTI there is high resistance rates to antimicrobial agents commonly used in primary care. There was no difference in the distribution of resistant E. coli in suspected uUTI vs cUTI. In Denmark, data from the National Surveillance program DANMAP can guide the decision for choice of antibiotic in patients with suspected UTI seeking care in primary care.

To identify the potential risk factors for urinary tract infections following midurethral sling procedures. 556 women who underwent midurethral sling procedure due to stress urinary incontinence over a four-year period were reviewed in this retrospective study. Of the study population, 280 women underwent TVT procedures and 276 women underwent TOT procedures. Patients were evaluated at 4-8 weeks postoperatively and were investigated for the occurrence of a urinary tract infection. Patients who experienced urinary tract infection were defined as cases, and patients who didn't were defined as controls. All data were collected from medical records. Multivariate logistic regression model was used to identify the risk factors for urinary tract infection. Of 556 women, 58 (10.4%) were defined as cases while 498 (89.6%) were controls. The mean age of women in cases (57.8±12.9years) was significantly greater than in controls (51.8±11.2years) (p<0.001). The presence of menopausal status, previous abdominal surgery, preoperative antibiotic treatment due to urinary tract infection, concomitant vaginal hysterectomy and cystocele repair, TVT procedure and postoperative postvoiding residual bladder volume ≥100ml were more common in cases than in controls. However, in multivariate regression analysis model presence of preoperative urinary tract infection [OR (95% CI)=0.1 (0.1-0.7); p=0.013], TVT procedure [OR (95% CI)=8.4 (3.1-22.3); p=0.000] and postoperative postvoiding residual bladder volume ≥100ml [OR (95% CI)=4.6 (1.1-19.2); p=0.036] were significant independent risk factors for urinary tract infection following midurethral slings CONCLUSION: Urinary tract infection after midurethral sling procedures is a relatively common complication. The presence of preoperative urinary tract infection, TVT procedure and postoperative postvoiding residual bladder volume ≥100ml may increase the risk of this complication. Identification of these factors could help surgeons to minimize this complicationby developing effective strategies. Copyright © 2017. Published by Elsevier B.V.

Secondary pseudohypoaldosteronism type 1 develops due to transient aldosterone resistance in renal tubules and is characterized by renal sodium loss, hyponatremia, hyperkalemia and high plasma aldosterone levels. Although many reasons are described, urinary tract infections and/or urinary tract anomalies are the most common causes. Although the cause of the tubular resistance is not known exactly, renal scar development due to obstruction and reduced sensitivity of mineralocorticoid receptors due to cytokines such as transforming growth factor (TGF)-beta are the possible mechanisms. It is seen especially within the first three months of life and the frequency decreases with age. The treatment is usually elimination of the underlying cause. In this article, we present four patients with several urinary tract anomalies and concomitant urinary tract infection who developed transient secondary pseudohypoaldosteronism.

Urinary tract infection associated with conditions causing urinary tract obstruction and stasis, excluding urolithiasis and neuropathic bladder.

The aim of this study was to examine urinary tract infection (UTI) associated with conditions causing urinary tract obstruction and stasis, excluding urolithiasis and neuropathic bladder dysfunction. An electronic literature search was performed using the key words urinary tract infection (UTI), benign prostatic hyperplasia (BPH), hydronephrosis, obstruction, reflux, diverticulum, urethra, and stricture. In total, 520 abstracts were reviewed, 210 articles were studied in detail, and 36 were included as references. It is one of the axioms of Urological practice that urinary tract obstruction and stasis predispose to UTI. Experimental studies indicate that, whereas transurethral inoculates of bacteria are rapidly eliminated from the normal bladder, urethral obstruction leads to cystitis, pyelonephritis, and bacteremia. BPH is, next to urolithiasis, the most common cause of urinary tract obstruction predisposing to UTI. Urethral stricture remains a common cause of UTI in many parts of the world. Urinary stasis in diverticula of the urethra or bladder predisposes to UTI. Experimental studies have shown that, whereas the normal kidney is relatively resistant to infection by organisms injected intravenously, ureteric obstruction predisposes to pyelonephritis. It also causes renal dysfunction which impairs the excretion of antibiotics in the urine, making eradication of bacteria difficult. In patients with UTI and urinary tract obstruction, targeted antibiotic treatment according to urine culture should be complemented with urgent drainage (bladder catheterization, percutaneous nephrostomy or ureteric stenting) followed by definitive surgery to remove the cause of obstruction or stasis once infection is under control.

Owing to evolution in treatment, the average life expectancy of patients with cystic fibrosis (CF) has increased. This has been followed by an increase in urological complications such as urinary incontinence. As stress incontinence occurs during exercise, it may have a negative effect on the implementation of respiratory physiotherapy. The purpose of this study is to determine the prevalence of urinary incontinence and its effect on the quality of life and physiotherapy in a population with CF. Questionnaires were used to determine the prevalence of incontinence in patients of the Cystic Fibrosis Clinic of the University Hospital in Brussels. Two different surveys were used, depending on the age of the patients (< 12 or ≥ 12 years). The different characteristics of incontinence were emphasized. Questionnaires were completed by 122 participants aged 6-59 years, showing an overall prevalence of 27% for urinary incontinence. Mainly adults reported urinary incontinence, with a prevalence of 11% in men and 68% in women aged 12 and above. The amount of urinary leakage was usually only a few drops and it was mainly triggered by coughing. Many of the participants had never mentioned this symptom to anyone. Doctors' and physical therapists' attention should be drawn to the fact that urinary incontinence is part of the complication spectrum of CF. A quarter of the study population refrained from coughing up phlegm and from physiotherapy. It is important to actively question and inform about this problem, to enable its detection and treatment.

Fanconi syndrome results from generalised renal tubular toxicity and, owing to phosphate wasting can cause hypophosphataemic osteomalacia. Large clinical trials advocated the safety of adefovir dipivoxil at a daily dose of 10 mg, the standard dose given to patients with hepatitis B. We diagnosed Fanconi syndrome in conjunction with severe osteomalacia in 2 hepatitis B-positive patients on standard-dose adefovir therapy. The first patient was a 40-year-old male with a 5 month history of bone pain involving his knees, ankles, and ribs. He had been receiving adefovir dipivoxil for 27 months before the development of hypophosphataemia, urinary phosphate wasting, and aminoaciduria. These abnormalities resolved within weeks of discontinuation of adefovir dipivoxil and supplementation with elemental phosphate, calcium carbonate, and cholecalciferol. The second patient was a 53-year-old female with a 6 month history of lethargy, cachexia, and generalized bone pain. She had been receiving adefovir for 64 months before the development of these symptoms. She had hypophosphataemia, hypocalcaemia, metabolic acidosis, and severe vitamin D deficiency, but initially no urinary phosphate wasting. Four months of high-dose cholecalciferol supplementation unmasked her Fanconi syndrome including significant urinary phosphate wasting. The patient improved within weeks of discontinuation of adefovir and supplementation with elemental phosphate, calcium carbonate, and calcitriol. Despite large clinical trials advocating the safety of adefovir dipivoxil at 10-mg daily, long-term use of this agent may be nephrotoxic and in rare cases, cause Fanconi syndrome and severe hypophosphataemic osteomalacia. Clinicians prescribing this drug should be aware of this potential complication.

To report our 10-year experience of sacral neurostimulation (SNS) for women in urinary retention, comparing the original one-stage with the newer two-stage technique, as SNS therapy is a well-established treatment for urinary retention secondary to urethral sphincter overactivity (Fowler's syndrome). Between 1996 and 2006, 60 patients with urinary retention had a SNS device inserted; their case records were reviewed and data on efficacy, follow-up, need for continued clean intermittent self-catheterization (CISC), complications and operative revision rate were assessed. Overall, 43 of 60 (72%) women were voiding spontaneously, with a mean postvoid residual volume of 100 mL; 30 (50%) no longer needed to use CISC. During a total of 2878 months of SNS experience, adverse event episodes included lead migration in 20, 'box-site' pain in 19, leg pain/numbness in 18 and loss of response/failure in 18 patients; 53% of the women required a surgical revision related to their implanted stimulator. The efficacy of the two-stage was similar to that of the one-stage procedure (73% vs 70%). Women with a normal urethral sphincter electromyogram had worse outcomes than women with an abnormal test (43% vs 76%). Although the efficacy was no different in those taking analgesia/antidepressant medication, this group of women had a higher surgical revision rate. Failure and complications for the one-stage procedure were not restricted to the early follow-up period. The mean battery life of the implant was 7.31 years. SNS has sustained long-term efficacy but the procedure has a significant complication rate. At present, the two-stage technique has comparable efficacy to the one-stage technique but a longer-term follow-up is required. The National Institute of Clinical Excellence recommended the use of SNS in women with urinary incontinence who fail to respond adequately to anticholinergic therapy, but patients choosing this treatment should be made aware of the high complication rate associated with the procedure.

Dermatan sulfate (DS) plays a number of roles in a wide range of biological activities such as cell signaling and tissue morphogenesis through interactions with various extracellular matrix proteins including collagen. Mutations in the carbohydrate sulfotransferase 14 gene (CHST14) encoding CHST14/dermatan 4-O-sulfotransferase-1 (D4ST1), which is responsible for the biosynthesis of DS, cause a recently delineated form of Ehlers-Danlos syndrome (EDS, musculocontractural type 1), an autosomal recessive connective tissue disorder characterized by congenital malformations (specific craniofacial features, and congenital multiple contractures) and progressive fragility-related complications (skin hyperextensibility, bruisability, and fragility with atrophic scars; recurrent dislocations; progressive talipes or spinal deformities; and large subcutaneous hematomas). In an attempt to develop a diagnostic screening method for this type of EDS, the amount of DS in the urine of patients was analyzed. Urinary DS was quantified by an anion-exchange chromatography after treatment with DS-specific degrading enzyme. DS was not detected in the urine of patients with homo- or compound heterozygous mutations in CHST14. These results suggest that the quantification of DS in urine is applicable to an initial diagnosis of DS-defective EDS. This is the first study to perform a urinary disaccharide compositional analysis of chondroitin sulfate (CS)/DS chains in patients with EDS caused by a CHST14/D4ST1 deficiency, and demonstrated the absence of DS chains. This result suggests systemic DS depletion in this disorder, and also proposes the usefulness of a urinary disaccharide compositional analysis of CS/DS chains as a non-invasive screening method for this disorder.

2016-01-01

Background Combined uterine and urinary bladder rupture following prolonged obstructed labor is indeed a momentous uro-obstetric emergency. The urinary bladder involvement is distinctly rare in the absence of factors that predispose the bladder to be adherent to the lower uterine segment and is quite unusual in a primigravida. Objective To report a rare case of uterine rupture involving urinary bladder secondary to a prolonged obstructed labor in a primigravida from a low resource setting. Case A 17-year-old married unbooked primigravida who presented with a 3-day history of spontaneous onset of labor at term that was initially managed at home and later in a primary health care center where she had fundal pressure and oxytocin augmentation, respectively. The labor was complicated by combined uterine and urinary bladder rupture with sepsis. She was resuscitated and had exploratory laparotomy with uterine and urinary bladder repair. The postoperative period was uneventful and she was followed-up at the gynecology and family planning clinics. Conclusion There is a need for community reawakening on the inherent risks of teenage pregnancy, bad obstetric practices, and unsupervised pregnancy, labor, and delivery, particularly in the rural settings as in the index patient. A high index of suspicion and prompt appropriate intervention will reduce the sequel of morbidity and occasional mortality from this predicament. PMID:27499647

[The Kock continent urinary diversion].

1989-07-01

The continent ileal reservoir as conceived by Kock produces a low-pressure, high-capacity reservoir with continent and nonrefluxing valves constructed from ileum. From August 1982 through March 1988, 531 patients underwent continent urinary diversion via a Kock reservoir at our institution. Of these, 39 males had a Kock bladder substitution, while the rest underwent cutaneous Kock diversion. Early complications occurred in 16% of all patients, and there was an operative mortality rate of 1.9%. Surgical modifications of nipple fixation, which are discussed in detail in this paper, help to reduce late complications to less than 10%. Patient satisfaction with both procedures remains excellent.

The TVT-Secur (Ethicon, Somerville, NJ, USA) is a minimally invasive suburethral synthetic sling used in the treatment of female stress urinary incontinence. It claims to cause less postoperative pain and to enable performing in an office setting. However, this may be at the expense of a significant learning curve and a higher early failure rate. To assess objectively the success rate of the TVT-Secur procedure in the 'U' configuration at six months. Secondary outcomes focussed on subjective success rates, complications, patient satisfaction and quality-of-life (QOL). A prospective observational study was undertaken at two tertiary referral urogynaecology centres. A cohort of 42 consecutive patients with urodynamic stress incontinence who underwent the TVT-Secur procedure in the 'U' configuration between November 2006 and August 2007 were followed up for six months. Three standardised QOL questionnaires were completed preoperatively and at six months. A urogenital history, visual analogue score (VAS) for patient satisfaction, uroflow and urinary stress test were performed at six months. Recruitment was ceased prematurely because of a high number of early failures. Objective and subjective success rates at six months were 58.3% and 51.3% respectively. Complications included urinary tract infections, voiding difficulty, groin discomfort, haematoma, vaginal pain, tape erosion and intra-operative dislodgement of tape. Prevalence of de novo urge incontinence was 10.3%. Only symptom-specific QOL scores improved and only 48.6% indicated a high level satisfaction (VAS > or = 80%) with TVT-Secur. On the basis of this limited study, we are hesitant to recommend the 'U' configuration of the TVT-Secur over its more established counterparts, the TVT and TVT-O.

Urinary tract infection is a common pregnancy complication. Asymptomatic bacteriuria (AB) can trigger the development of serious complications affecting both the mother and the fetus. Determine the frequency of AB among pregnant women attending to antenatal care at the family medicine clinic number 1 of the Instituto Mexicano del Seguro Social, located in Ciudad Obregón, Sonora. A longitudinal study was carried out from September to December 2004. Seventy-two 72 pregnant women with gestational age of 24 weeks or less were followed up during four months. All pregnant women were selected by a non-probabilistic method. Every patient had a monthly urine culture during the follow up period. Among the 72 pregnant women, 16.7% developed symptomatic urinary infections during the follow-up and 25% had at least one positive urine culture without urinary symptoms, being classified as AB, thus receiving treatment. Frequency of positive urine cultures was common at first and fourth months of follow-up. Urine culture is an important component of prenatal care, and helps in identifying a significant number of urinary tract infections that would go otherwise undetected.

Recently, nerve-sparing (NS) techniques have been incorporated in surgeries for deep infiltrating endometriosis (DIE) to prevent urinary complications. Our aim was to perform a systematic review and meta-analysis to assess the risk of urinary retention after NS surgery for DIE compared with classical (non-NS) techniques. Following the MOOSE guidelines for systematic reviews of observational studies, data were collected from published research articles that compared NS techniques with non-NS techniques in DIE surgery, with regard to post-operative urinary complications. randomized clinical trials, intervention or observational (cohort and case-control) studies assessing women who underwent surgery for painful DIE. cancer surgery and women submitted to bladder or ureteral resections. The respective relative risks (RR) and 95% confidence intervals (CI) were extracted and a forest plot was generated to show individual and combined estimates. Preliminarily, 1,270 potentially relevant studies were identified from which four studies were selected. A meta-analysis was performed to assess the risk of urinary retention at discharge and 90 days after surgery. We found a common RR of 0.19 [95%CI: 0.03-1.17; (I 2  = 50.20%; P = 0.09)] for need of self-catheterization at discharge in the NS group in relation to the conventional technique. Based on two studies, common RR for persistent urinary retention (after 90 days) was 0.16 [95%CI: 0.03-0.84]. Our results suggest significant advantages of the NS technique when considering the RR of persistent urinary retention. Controlled studies evaluating the best approach to manage the urinary tract after complex surgery for DIE are needed. Neurourol.

To extract the causes and risk factors of urinary incontinence from an old medical text by Avicenna entitled "Canon of Medicine" and comparing it with contemporary studies. In this study, etiology and risk factors of urinary incontinence were extracted from Avicenna's "Canon of Medicine". Commentaries written on this book and other old reliable medical texts about bladder and its diseases were also studied. Then the achieved information was compared with contemporary findings of published articles. Urinary incontinence results from bladder dysfunction in reservoir phase. Bladder's involuntary muscles and voluntary external sphincter are two main components which are involved in this process. Urinary incontinence can exist without obvious structural and neuronal etiologies. According to Avicenna, distemperment of muscular tissue of bladder and external sphincter is the cause for urinary incontinence in such cases. Distemperment is the result of bothering qualities in tissue, i.e.: "wet" and "cold". They are the two bothering qualities which are caused by extracorporeal and intracorporeal factors. Interestingly, the positive associations of some of these factors with urinary incontinence have been shown in recent researches. "Cold" and "wet" distemperment of bladder and external sphincter can be independent etiologies of urinary incontinence which should be investigated.

The use of fragmentation due to shock- waves as a treatment of urinary stone was one of the most important therapeutics findings in the history of urology. It's the first election treatment for most of the calculus at renal and urethral location due to the fact that it is a low invasive treatment and it has a few number of complications, but this method also has a few negative side effects, it can caused a more or less important traumatic lesion at the organs which crosses the shock-waves, including the kidney where it can caused a small contusion or renal hematoma with different resolution and treatment. We reviewed 4815 extracorporeal shock-wave lithotripsy that we performed in our department in which we found six cases with subcapsular and perirenal hematoma which we followed up and treated. After the urological complications (pain, obstruction and infection) the renal and perirenal hematic collections are the most frequent adverse effects of shock-waves used in lithotripsy, these are related to the power of energy used and patient age. Between the years 1992-2007 we performed 4.815 extracorporeal shock-wave lithotripsy finding seven cases of severe hematoma, less then 1%. Treatment of these complications is usually not aggressive though sometimes it is necessary to perform surgical drainage and even nephrectomy.

Diabetes mellitus is estimated to affect ∼24 million people in the United States and more than 150 million people worldwide. There are numerous end organ complications of diabetes, the onset of which can be delayed by early diagnosis and treatment. Although assays for diabetes are well founded, tests for its complications lack sufficient specificity and sensitivity to adequately guide these treatment options. In our study, we employed a streptozotocin-induced rat model of diabetes to determine changes in urinary protein profiles that occur during the initial response to the attendant hyperglycemia (e.g. the first two months) with the goal of developing a reliable and reproducible method of analyzing multiple urine samples as well as providing clues to early markers of disease progression. After filtration and buffer exchange, urinary proteins were digested with a specific protease, and the relative amounts of several thousand peptides were compared across rat urine samples representing various times after administration of drug or sham control. Extensive data analysis, including imputation of missing values and normalization of all data was followed by ANOVA analysis to discover peptides that were significantly changing as a function of time, treatment and interaction of the two variables. The data demonstrated significant differences in protein abundance in urine before observable pathophysiological changes occur in this animal model and as function of the measured variables. These included decreases in relative abundance of major urinary protein precursor and increases in pro-alpha collagen, the expression of which is known to be regulated by circulating levels of insulin and/or glucose. Peptides from these proteins represent potential biomarkers, which can be used to stage urogenital complications from diabetes. The expression changes of a pro-alpha 1 collagen peptide was also confirmed via selected reaction monitoring. PMID:19497846

Urinary and (peripheral and central) intravenous catheters are widely used in hospitalized patients. However, up to 56% of the catheters do not have an appropriate indication and some serious complications with the use of these catheters can occur. The main objective of our quality improvement project is to reduce the use of catheters without an appropriate indication by 25-50%, and to evaluate the affecting factors of our de-implementation strategy. In a multicenter, prospective interrupted time series analysis, several interventions to avoid inappropriate use of catheters will be conducted in seven hospitals in the Netherlands. Firstly, we will define a list of appropriate indications for urinary and (peripheral and central) intravenous catheters, which will restrict the use of catheters and urge catheter removal when the indication is no longer appropriate. Secondly, after the baseline measurements, the intervention will take place, which consists of a kick-off meeting, including a competitive feedback report of the baseline measurements, and education of healthcare workers and patients. Additional strategies based on the baseline data and local conditions are optional. The primary endpoint is the percentage of catheters with an inappropriate indication on the day of data collection before and after the de-implementation strategy. Secondary endpoints are catheter-related infections or other complications, catheter re-insertion rate, length of hospital (and ICU) stay and mortality. In addition, the cost-effectiveness of the de-implementation strategy will be calculated. This study aims to reduce the use of urinary and intravenous catheters with an inappropriate indication, and as a result reduce the catheter-related complications. If (cost-) effective it provides a tool for a nationwide approach to reduce catheter-related infections and other complications. Dutch trial registry: NTR6015 . Registered 9 August 2016.

To assess the effectiveness and complications associated with single and double-cuff artificial urinary sphincter (AUS) implantation for postprostatectomy stress urinary incontinence. A retrospective study of 56 men with postprostatectomy stress urinary incontinence who underwent either single (28 patients) or double (28 patients) cuff AUS placement was performed. Patients in each cohort were matched on the basis of preoperative pad use, risk factors for complications, and age. Patient selection was blinded relative to outcome. Continence, quality of life, and complications were assessed using the Incontinence Impact Questionnaire Short Form (IIQ-7), postoperative pad use, and chart review. The mean age was 67 years for each group. Daily pad use decreased from 7.7 to 1.1 in patients treated with a single-cuff AUS and from 7.8 to 0.7 in patients with a double-cuff AUS (P = 0.25). Complete continence (0 pads daily) was reported in 3 (11%) of 28 men with single-cuff and 12 (43%) of 28 men with double-cuff sphincters (P = 0.008). The IIQ-7 scores improved from 14.8 to 3.1 after single-cuff placement and from 16.3 to 2.5 after double-cuff placement (P = 0.03). With an average follow-up of 41.3 and 21.2 months for the single and double-cuff cohorts, respectively, five complications were reported in the single-cuff recipients and four in the double-cuff patients. A significantly greater rate of complete continence and improvement in the IIQ-7 were seen in men with double-cuff AUS compared with single-cuff devices. Additional study is needed to confirm the relative advantages of double-cuff insertion.

Diagnosis and management of fungal urinary tract infection.

When the terms funguria or fungal urinary tract infection are used, most physicians are referring to candiduria and urinary tract infections due to Candida species. Other fungi, including yeasts and molds can involve the kidney during the course of disseminated infection, but rarely cause symptoms referable to the urinary tract. Candida species appear to be unique in their ability to both colonize and cause invasive disease in the urinary tract. This overview focuses only on candiduria and Candida urinary tract infection because they are common and many times present perplexing management issues. Published by Elsevier Inc.

Herpes zoster infection: a rare cause of acute urinary retention.

PubMed

Chan, Jonathan E; Kapoor, Anil

2003-06-01

Herpes zoster (HZ) infection has been reported as a rare cause of acute urinary retention. HZ infection involving sacral, thoracolumbar, and rarely high thoracic dermatomes is believed to occasionally cause motor and sensory neuropathy of the bladder. This is specifically achieved by the interruption of the detrusor reflex causing subsequent bladder atonia. As the course and management of this entity is quite benign, HZ should remain a diagnostic consideration in the management of urinary retention. We report a case of acute urinary retention of approximately 2.5 liters associated with HZ infection and review the proposed pathogenesis and therapeutic considerations in the management of this entity.

The aim of this article is to identify the ideal type and location of colostomy in children with colorectal disease. A retrospective case study of children with an anorectal malformation who received a colostomy, born between January 1990 and July 2012. Furthermore, a systematic literature search on colostomies in neonates with an anorectal malformation or Hirschsprung disease. Colostomies were classified as loop or split colostomies in the transverse or sigmoid colon. Outcome measures were mortality and complications such as prolapse, technical difficulties with the reconstruction, urinary tract infections, and others. The mortality rate in the 180 children with anorectal malformation was 6%, and none of them were directly related to stoma formation or closure. The overall complication rate was 23% and the specific rates for the two types of procedures and the two locations of the colostomy did not differ (p = 0.389 and p = 0.667, respectively). All prolapses (n = 22) occurred in loop colostomies in the transverse colon. One colostomy required revision because of insufficient length for the reconstruction. Urinary tract infections were not documented. A total of eight studies were included in the systematic review (1982-2011; 2,954 patients). Mortality ranged between 0.1 and 11%. Loop colostomies had more complications than split colostomies (63 vs. 45%; p = 0.007), mainly prolapse (18 vs. 6%; p < 0.001). Overall complication rate differed between transverse en sigmoid colostomies (62 vs. 51%, p = 0.006), and prolapse occurred more often in the transverse colon (23 vs. 7%; p < 0.001). Revision because of insufficient length during the reconstruction was needed in 0 to 6%. Two studies reported on urinary tract infections which are as follows: One showed no difference between loop or split colostomies, whereas the other showed frequent episodes of urinary tract infections in 64% of the loop colostomies. The complication to be avoided in transverse colostomies is prolapse and the surgical technique should be modified accordingly. The procedure of split sigmoid colostomy is meticulous, and the risk of insufficient length for the reconstruction remains. Georg Thieme Verlag KG Stuttgart · New York.

[Efficacy of probiotic bactisporin in therapy of intrahospital urinary infection].

Pushkarev, A M

2005-01-01

We studied efficacy of bactisporin (probiotic based on aerobic spore-forming culture Bacillus subtilis, strain 3H) in combined treatment of intrahospital urinary infection (IUI) in 36 patients with infravesical obstruction. These patients developed postoperative complications due to IUI caused by antibiotic-resistant hospital flora. The control group consisted of 35 patients matched by age and disease given conventional postoperative etiotropic therapy. Bacterial translocation enables bactisporin to enter blood through gastric mucosa. Blood flow delivered the drug to the inflammation focus. Bactisporin can also directly affect IUI pathogen if bacterial suspension is introduced into the cavity. Bacteriological efficacy of the etiotropic scheme including bactisporin against Proteus spp., Ps aeruginosa, Enterobacter spp., Klebsiella spp. made up 72.7-92%. Bactisporin shortened the time of clinical normalization as well as normalization of absolute count of T- and B-lymphocytes, phagocyting leukocytes and immunoglobulin G. Thus, probiotic bactisporin is effective against antibiotic-resistant agents of IUI. It also stimulates immunity promoting clinicoimmunological remission.

Preventing urinary tract infection: progress toward an effective Escherichia coli vaccine

PubMed Central

Brumbaugh, Ariel R; Mobley, Harry LT

2012-01-01

Uncomplicated urinary tract infections (UTIs) are common, with nearly half of all women experiencing at least one UTI in their lifetime. This high frequency of infection results in huge annual economic costs, decreased workforce productivity and high patient morbidity. At least 80% of these infections are caused by uropathogenic Escherichia coli (UPEC). UPEC can reside side by side with commensal strains in the gastrointestinal tract and gain access to the bladder via colonization of the urethra. Antibiotics represent the current standard treatment for UTI; however, even after treatment, patients frequently suffer from recurrent infection with the same or different strains. In addition, successful long-term treatment has been complicated by a rise in both the number of antibiotic-resistant strains and the prevalence of antibiotic-resistance mechanisms. As a result, preventative approaches to UTI, such as vaccination, have been sought. This review summarizes recent advances in UPEC vaccine development and outlines future directions for the field.

Aerococcus urinae in urinary tract infections.

PubMed

Zhang, Q; Kwoh, C; Attorri, S; Clarridge, J E

2000-04-01

Aerococcus urinae is a rarely reported pathogen, possibly due to difficulties in the identification of the organism. A. urinae is a gram-positive coccus that grows in pairs and clusters, produces alpha-hemolysis on blood agar, and is negative for catalase and pyrrolidonyl aminopeptidase. Some of these characteristics and its being absent from the databases of most commercial identification systems could allow A. urinae to be misidentified as a streptococcus, enterococcus, or staphylococcus. We report two cases of urinary tract infection (UTI) caused by A. urinae and characterize these isolates by morphology, biochemical testing, whole-cell fatty acid analysis, 16S rRNA gene sequencing, and antibiotic susceptibilities. Most patients infected with A. urinae are elderly males with predisposing conditions who present initially with UTI. Because A. urinae is resistant to sulfonamides, treatment could be inappropriate, with infections resulting in serious complications, including death. It is important for the clinician and the microbiologist to consider A. urinae a potential pathogen and proceed with thorough microbiological identification.

Background To examine the association between patient complications and admission to level 1 trauma centers (TC) compared to non-trauma centers (NTC). Study Design A retrospective cohort study of data derived from the National Study on the Costs and Outcomes of Trauma (NSCOT). Patients were recruited from 18 level 1 TC and 51 NTC in 15 regions encompassing 14 states. Trained study nurses, using standardized forms, abstracted the medical records of the patients. The overall number of complications per patient was identified as well as the presence or absence of 13 specific complications. Results Patients treated in TC were more likely to have any complication compared to NTC with an adjusted relative risk (RR) of 1.34 (95% CI 1.03, 1.74). For individual complications, only urinary tract infection RR 1.94 (95% CI 1.07, 3.17) was significantly higher in TC. TC patients were more likely to have three or more complications, RR 1.83 (95% CI 1.16, 2.90). Treatment variables that are surrogates for markers of injury severity, such as use of pulmonary artery catheters, multiple operations, massive transfusions (> 2,500mL packed red blood cells), and invasive brain catheters, occurred significantly more often in TC. Conclusions Trauma centers have a slightly higher incidence rate of complications even after adjusting for patient case mix. Aggressive treatment may account for a significant portion of TC-associated complications. PA catheter use and intubation had the most influence on overall TC complication rates. Further study is needed to provide accurate benchmark measures of complication rates and to determine their causes. PMID:19854399

Cefiderocol, a novel parenteral siderophore cephalosporin, exhibits potent efficacy against most Gram-negative bacteria, including carbapenem-resistant strains. The aim of this study was to perform a population pharmacokinetic (PK) analysis based on plasma cefiderocol concentrations in healthy subjects, subjects with various degrees of renal function, and patients with complicated urinary tract infection (cUTI) or acute uncomplicated pyelonephritis (AUP) caused by Gram-negative pathogens and to calculate the fraction of the time during the dosing interval where the free drug concentration in plasma exceeds the MIC ( fT MIC ). Population PK models were developed with three renal function markers, body surface area-adjusted estimated glomerular filtration rate (eGFR), absolute eGFR, and creatinine clearance, on the basis of 2,571 plasma concentrations from 91 subjects without infection and 238 patients with infection. The population PK models with each renal function marker adequately described the plasma cefiderocol concentrations. Clear relationships of total clearance (CL) to all renal function markers were observed. Body weight and disease status (with or without infection) were also significant covariates. The CL in patients with infection was 26% higher than that in subjects without infection. The fT MIC values were more than 75% in all patients (and were 100% in most patients), suggesting that a sufficient exposure to cefiderocol was provided by the tested dose regimens (2 g every 8 h as the standard dose regimen) for the treatment of cUTI or AUP caused by Gram-negative pathogens.

Recurrent urinary tract infections in women: How promising is the use of probiotics?

PubMed

Gupta, Varsha; Nag, Deepika; Garg, Pratibha

2017-01-01

Urinary tract infections (UTIs) currently rank amongst the most prevalent bacterial infections, representing a major health hazard. UTIs in females usually start as vaginal infections and ascend to the urethra and bladder. Recurrent UTIs (rUTIs) can be defined as at least three episodes of UTI in 1 year or two episodes in 6 months. Various antibiotics have been the mainstay of therapy in ameliorating the incidence of UTIs, but recurrent infections continue to afflict many women. It necessitates the exploitation of alternative antimicrobial therapy. Probiotics have been shown to be effective in varied clinical trials for long-term preventions of rUTI. Because Escherichia coli is the primary pathogen involved in UTIs which spreads from the rectum to vagina and then ascends up the sterile urinary tract, improving the gut or vaginal flora will thus impact the urinary tract. Since a healthy vaginal microbiota is mainly dominated by Lactobacillus species, in this context, exogenously administered probiotics containing Lactobacilli play a pivotal role in reducing the risk of rUTI. The concept of artificially boosting the Lactobacilli numbers through probiotic administration has long been conceived but has been recently shown to be possible. Lactobacilli may especially be useful for women with a history of recurrent, complicated UTIs or on prolonged antibiotic use. Probiotics do not cause antibiotic resistance and may offer other health benefits due to vaginal re-colonisation with Lactobacilli. However, more comprehensive research is still needed, to recommend for probiotics as an alternative to antibiotics.

Transcriptome of Proteus mirabilis in the Murine Urinary Tract: Virulence and Nitrogen Assimilation Gene Expression▿†

Pearson, Melanie M.; Yep, Alejandra; Smith, Sara N.; Mobley, Harry L. T.

2011-01-01

The enteric bacterium Proteus mirabilis is a common cause of complicated urinary tract infections. In this study, microarrays were used to analyze P. mirabilis gene expression in vivo from experimentally infected mice. Urine was collected at 1, 3, and 7 days postinfection, and RNA was isolated from bacteria in the urine for transcriptional analysis. Across nine microarrays, 471 genes were upregulated and 82 were downregulated in vivo compared to in vitro broth culture. Genes upregulated in vivo encoded mannose-resistant Proteus-like (MR/P) fimbriae, urease, iron uptake systems, amino acid and peptide transporters, pyruvate metabolism enzymes, and a portion of the tricarboxylic acid (TCA) cycle enzymes. Flagella were downregulated. Ammonia assimilation gene glnA (glutamine synthetase) was repressed in vivo, while gdhA (glutamate dehydrogenase) was upregulated in vivo. Contrary to our expectations, ammonia availability due to urease activity in P. mirabilis did not drive this gene expression. A gdhA mutant was growth deficient in minimal medium with citrate as the sole carbon source, and loss of gdhA resulted in a significant fitness defect in the mouse model of urinary tract infection. Unlike Escherichia coli, which represses gdhA and upregulates glnA in vivo and cannot utilize citrate, the data suggest that P. mirabilis uses glutamate dehydrogenase to monitor carbon-nitrogen balance, and this ability contributes to the pathogenic potential of P. mirabilis in the urinary tract.

To investigate the change in urinary urgency and predictors of urgency improvement after holmium laser enucleation of the prostate (HoLEP) in men with benign prostatic hyperplasia (BPH). We retrospectively analyzed the medical records of patients who were treated with HoLEP for BPH and had preoperative urgency measuring ≥3 on a 5-point urinary sensation scale. Those with prostate cancer diagnosed prior to or after HoLEP, a history of other prostatic and/or urethral surgery, moderate to severe postoperative complications, and neurogenic causes were excluded. Patients who had improved urgency with antimuscarinic medication after HoLEP were excluded. We divided the patients into 2 groups based on urgency symptoms 3 months after HoLEP: improved and unimproved urgency. Improved urgency was defined as a reduction of 2 or more points on the 5-point urinary sensation scale. Preoperative clinical and urodynamic factors as well as perioperative factors were compared between groups. In total, 139 patients were included in this study. Voiding parameters in all patients improved significantly after HoLEP. Seventy-one patients (51.1%) had improved urgency, while 68 (48.9%) did not show any improvement. A history of acute urinary retention (AUR) and postvoid residual were associated with postoperative urgency improvement in univariate analysis. In multivariate analysis, a history of AUR was an independent factor affecting urgency improvement. A preoperative history of AUR could influence the change in urgency after HoLEP surgery in patients with BPH.

To reduce short-term complications of radical cystectomy (RC) and intestinal urinary diversion with vescica ileale Padovana (VIP) neobladder, we described and assessed an enhanced recovery protocol (ERP) in a series of consecutive patients. An ERP was introduced focusing on reduced bowel preparation, standardized feeding and analgesic regimens. We analyzed the outcomes with all patients consecutively undergoing RC and VIP neobladder who met the following inclusion criteria: American Society of Anesthesiologists score <3; absence of malnutrition according to the Mini Nutritional Assessment-Short Form criteria; absence of inflammatory bowel diseases. Thirty-one consecutive patients were recruited to undergo our ERP. Mean age of patients was 62.16 years. No patients died due to surgical complications. Nine of 31 patients experienced complications (29.03%), none requiring surgical intervention. According to Clavien grading, all complications were grade <2. The application of our ERP to our patients undergoing RC and VIP neobladder contributed to reduce postoperative morbidity. Copyright © 2013 S. Karger AG, Basel.

Surgical Management of Neurogenic Lower Urinary Tract Dysfunction.

PubMed

Gor, Ronak A; Elliott, Sean P

2017-08-01

Surgery for patients with neurogenic urinary tract dysfunction (nLUTD) is indicated when medical therapy fails, to correct conditions affecting patient safety, or when surgery can enhance the quality of life better than nonoperative management. Examples include failure of maximal medical therapy, inability to perform or aversion to clean intermittent catheterization, refractory incontinence, and complications from chronic, indwelling catheters. Adults with nLUTD have competing risk factors, including previous operations, obesity, poor nutritional status, complex living arrangements, impaired dexterity/paralysis, and impaired executive and cognitive function. Complications are common in this subgroup of patients requiring enduring commitments from surgeons, patients, and their caretakers. Copyright © 2017 Elsevier Inc. All rights reserved.

A total of 61 patients with lower urinary tract injuries were treated at Nara Medical University and its affiliated hospitals, between January 1985 and June 1995. There were 9 patients with bladder injuries and 52 patients with urethral injuries. The main cause of bladder injury was a traffic accident sustained in 4 patients (44.5%) and that of urethral injury was an occupational accident sustained in 27 cases (51.9%). The major associated injuries were a bone fracture seen in 45 patients (73.8%) and an intrascrotal hematoma seen in 28 patients (45.9%). Posterior urethral injuries associated with pelvic bone fractures were classified into 3 types according to the classification reported by Colapinto et al.; 8 patients (32.0%) into Type I, 8 (32.0%) into Type II and 9 (36.0%) into Type III. Of the 25 patients with posterior urethral injuries, 8 (32.0%) underwent immediate surgical treatment, 12 (48.0%) underwent initial cystostomies and delayed surgical treatment and 5 (20.0%) received indwelling of urethral catheters. Postoperative complications of urethral injury included urethral stricture in 30 patients (57.7%), incontinence in 3 (5.8%) and impotence in 3 (5.8%). A significant relationship between the duration of cystostomy and the incidence of postoperative urethral stricture was observed in our patients. Therefore at least three weeks of cystostomy will be necessary in the management of patients with complicated urethral injuries.

To measure 11-dehydro-thromboxane B2 (11-dTXB2) in urine of healthy control dogs, dogs undergoing ovariohysterectomy, and dogs with gastric dilatation-volvulus (GDV) and assess the relationship between urinary 11-dTXB2 concentrations in dogs with GDV and postoperative outcomes. Urine samples from 15 nonsurgical control dogs, 12 surgical control dogs, and 32 dogs with GVD. Urine samples were obtained from healthy pet dogs (ie, nonsurgical control dogs), dogs undergoing ovariohysterectomy at anesthetic induction and 1 hour following surgery (ie, surgical control dogs), and dogs with GDV at hospital admission and 1 hour following surgical derotation of the stomach (ie, GDV dogs). Urinary 11-dTXB2 concentrations were determined with an ELISA and normalized to urinary creatinine (Cr) concentrations by calculation of the 11-dTXB2 -to-Cr ratio. Differences in median 11-dTXB2 -to-Cr ratios among dogs and before and after surgery were analyzed. Urinary 11-dTXB2-to-Cr ratios did not differ between nonsurgical control dogs and surgical control dogs before or after surgery. Urinary 11-dTXB2-to-Cr ratios were significantly higher in GDV dogs at the time of hospital admission and 1 hour after surgery, compared with those of nonsurgical control dogs. Postoperative urine samples from GDV dogs had significantly higher 11-dTXB2-to-Cr ratios than postoperative urine samples from surgical control dogs. Median urinary 11-dTXB2-to-Cr ratios increased significantly in GDV dogs that developed postoperative complications. Urinary 11-dTXB2 concentration is increased in GDV dogs at the time of hospital admission and after surgical derotation of the stomach, compared with that of healthy dogs. An increased urinary 11-dTXB2-to-Cr ratio following surgery is associated with an increased incidence of postoperative complications in dogs with GDV.

Proteomic analysis of urine in patients with intestinal segments transposed into the urinary tract.

Intestinal segments are used to replace or reconstruct the urinary bladder when it has become dysfunctional or develops life-threatening disease such as cancer. The quality of life in patients with intestinal segments used to either enlarge or completely replace the native bladder is adversely affected by recurrent urinary tract infections, excessive mucus production and the occasional development of malignancy. At present, there is no reliable method of predicting or noninvasively monitoring these patients for the development of these complications. The characterisation of proteins secreted into urine from the transposed intestinal segments could serve as important indicators of these clinical complications. Urine is an ideal source of material in which to search for biomarkers, since it bathes the affected tissues and can be obtained relatively easily by noninvasive methods. The urinary proteome of patients with intestinal segments transposed into the urinary tract is unknown and we present the first global description of the urinary protein profile in these patients. Sample preparation is a critical step in achieving accurate and reliable data. We describe a method to prepare urinary proteins that was compatible with their subsequent analysis using two-dimensional polyacrylamide gel electrophoresis. This method helped to overcome some of the technical problems encountered in analysing urine from this patient cohort. The method was used to analyse urinary proteins recovered from five healthy controls and ten patients with intestinal segments transposed into the urinary tract. Four low molecular weight proteins were found to be present in nine out of ten for the patient group but for none of the healthy controls. The four proteins were identified as lithostathine-1 alpha precursor, pancreatitis associated protein-1 precursor, liver fatty acid binding protein and testis expressed protein-12. The role of these proteins as potential biomarkers of intestinal cell activity within the reconstructed bladder is discussed.

An Unusual Complication of Ventriculoperitoneal Shunt: Urinary Bladder Stone Case Report and Literature Review.

2016-01-01

Ventriculoperitoneal (V-P) shunt surgery is the most common technique used for the treatment of hydrocephalus. The migration of ventriculoperitoneal shunt to the bladder is rare. Only two cases have been previously reported in the literature. We report on a 38-year-old male who had hydrocephalus and V-P shunt for 12 years. Two years ago, he found himself with recurrent urinary tract infections, haematuria and urges incontinence, and then he was diagnosed with bladder perforation and merge stones. The patient had an abdominal operation to cut off and take out the shunt catheter, as well as a transurethral holmium laser lithotripsy. Bladder perforation and stones are rare examples of complications in V-P surgical procedures. Controlling the effective length of the terminal V-P shunt and modifying it appropriately can effectively reduce these complications.

Impact of gender on 30-day complications has been investigated in other surgical procedures but has not yet been studied in total hip arthroplasty (THA) or total knee arthroplasty (TKA). Patients who received THA or TKA from 2012 to 2014 were identified in the National Surgical Quality Improvement Program database. Patients were divided into 2 groups based on gender. Bivariate and multivariate analyses were performed to assess associations between gender and patient factors and complications after THA or TKA and to assess whether gender was an independent risk factor. THA patients consisted of 45.1% male and 54.9% female. In a multivariate analysis, female gender was found to be a protective factor for mortality, sepsis, cardiovascular complications, unplanned reintubation, and renal complications and as an independent risk factor for urinary tract infection, blood transfusion, and nonhome discharge after THA. TKA patients consisted of 36.7% male and 62.3% female. Multivariate analysis revealed female gender as a protective factor for sepsis, cardiovascular complications, and renal complications and as an independent risk factor for urinary tract infection, blood transfusion, and nonhome discharge after TKA. There are discrepancies in the THA or TKA complications based on gender, and the multivariate analyses confirmed gender as an independent risk factor for certain complications. Physicians should be mindful of patient's gender for better risk stratification and informed consent. Copyright © 2017 Elsevier Inc. All rights reserved.

Complications and their risk factors following hip fracture surgery.

PubMed

Poh, Keng Soon; Lingaraj, K

2013-08-01

PURPOSE. To evaluate various postoperative complications and their risk factors in hip fracture patients. METHODS. 207 female and 87 male consecutive patients (mean age, 78.1 years) who underwent surgical (n=242) or conservative (n=52) treatment for closed fractures of the femoral neck (n=157) or peritrochanter (n=137) were prospectively studied. The types of complication and outcome were recorded. The comorbidity status of the patients was categorised based on the American Society of Anesthesiologists (ASA) classification. Complications and their associations with various risk factors and mortality were analysed. RESULTS. For all patients, the mean length of hospitalisation was 14.6 days. For the 242 patients who underwent surgical treatment after a mean of 3.6 days, 56.8% of them had at least one complication. Acute urinary retention (39.3%) and urinary tract infection (24.0%) were most common. Patients with ASA grade III or higher had 2.3 fold higher risk of developing complications than those with lower-grade comorbidity, whereas patients with delayed operation (>48 hours after presentation) had 1.8 fold higher risk of developing complications than those without delayed operation. Four patients died in hospital: 2 from myocardial infarction and 2 from upper gastrointestinal bleeding. CONCLUSION. Complications after hip fracture surgery were common. Advanced age, high ASA status, and delay in surgery were associated with higher complication rates. Operations should be performed on medically fit patients as early as possible.

Urinary stone disease is a major urological condition. Endourologic techniques have influenced the clinical approach and outcomes. Open surgery holds a historic importance in the management of most conditions. However, complex kidney stone burden may be amenable to successful results with open stone surgery. In this article, we report our eighteen cases of complex urinary stone disease who underwent open stone removal. A total of 1701 patients have undergone surgical treatment for urinary stone disease in our clinic between July 2012 and July 2016, comprising eighteen patients who underwent open stone surgery. Patients' demographic data, stone analysis results, postoperative clinical data, and stone status were evaluated retrospectively. The choice of surgical approach is mostly dependent on the surgeon's preference. In two patients, open surgery was undertaken because of perioperative complications. We did not observe any Clavien-Dindo grade 4 or 5 complications. Three patients were managed with a course of antibiotics due to postoperative fever. One patient had postoperative pleurisy, one patient had urinoma, and two patients had postoperative ileus. Mean operation time was 84 (57-124) minutes and mean hospitalization time was 5.5 (3-8) days. Stone-free status was achieved in 15 patients (83.3%). Endourologic approaches are the first options for treatment of urinary stone disease. However, open stone surgery holds its indispensable position in complicated cases and in complex stone burden. Open stone surgery is also a valid alternative to endourologic techniques in all situations.

1994-01-01

The causes of bacteriotoxic shock were examined in 33 patients (11 lethal outcomes). It has arisen as a complication of treatment given to 7830 patients for urolithiasis. Aggravation of chronic pyelonephritis, occlusion of the urinary tracts, urogenital mucosal and parenchymal injuries, low resistance to infection contribute to microbacteria and their toxins entering blood with resultant bacteriotoxic shock. Transcutaneous operative interventions, therapeutic and diagnostic procedures also produce high risk of blood infection with gram-negative microflora, especially in violation of asepsis and antisepsis rules. As shown by microflora tests, the dominating bacteria consisted of opportunistic agents which had acquired the resistance to antibacterial drugs. In view of rapid progression of bacteriotoxic shock therapeutic efforts should be concentrated on fast normalization of hemodynamics, recovery of urine passage, introduction of sorption detoxication, prevention of DIC syndrome. The schemes of combined antibiotic treatment adjusted to the kind of infectious agent are suggested.

The differential diagnosis of abdominal pain is broad in any child, and further complicated in children with sickle cell disease (SCD). Acute causes of abdominal pain may require emergent surgery, such as for appendicitis or obstruction caused by a bezoar. Rapid intervention is necessary and life-saving in children with SCD and acute splenic or hepatic sequestration. The majority of children with SCD presenting to the physician's office or emergency department will have subacute reasons for their abdominal pain, including but not limited to constipation, urinary tract infection, peptic ulcer disease, and cholecystitis. Vaso-occlusive pain often presents in children as abdominal pain, but is a diagnosis of exclusion. The case of a 10-year-old girl with intermittent abdominal pain is used as a starting point to review the pathophysiology, diagnosis, and treatment of the most acute and common causes of abdominal pain in children with SCD.

Gram-positive bacteria in the genus Enterococcus are a frequent cause of catheter-associated urinary tract infection (CAUTI), a disease whose treatment is increasingly challenged by multiantibiotic-resistant strains. We have recently shown that E. faecalis uses the Ebp pilus, a heteropolymeric surface fiber, to bind the host protein fibrinogen as a critical step in CAUTI pathogenesis. Fibrinogen is deposited on catheters due to catheter-induced inflammation and is recognized by the N-terminal domain of EbpA (EbpA NTD ), the Ebp pilus's adhesin. In a murine model, vaccination with EbpA NTD confers significant protection against CAUTI. Here, we explored the mechanism of protection using passive transfer of immune sera to show that antisera blocking EbpA NTD -fibrinogen interactions not only is prophylactic but also can act therapeutically to reduce bacterial titers of an existing infection. Analysis of 55 clinical CAUTI, bloodstream, and gastrointestinal isolates, including E. faecalis, E. faecium, and vancomycin-resistant enterococci (VRE), revealed a diversity of levels of EbpA expression and fibrinogen-binding efficiency in vitro Strikingly, analysis of 10 strains representative of fibrinogen-binding diversity demonstrated that, irrespective of EbpA levels, EbpA NTD antibodies were universally protective. The results indicate that, despite diversity in levels of fibrinogen binding, strategies that target the disruption of EbpA NTD -fibrinogen interactions have considerable promise for treatment of CAUTI. Urinary catheterization is a routine medical procedure, and it has been estimated that 30 million Foley catheters are used annually in the United States. Importantly, placement of a urinary catheter renders the patient susceptible to developing a catheter-associated urinary tract infection, accounting for 1 million cases per year. Additionally, these infections can lead to serious complications, including bloodstream infection and death. Enterococcus strains are a common cause of these infections, and management of enterococcal infections has been more difficult in recent years due to the development of antibiotic resistance and the ability of strains to disseminate, resulting in a major threat in hospital settings. In this study, we developed an antibiotic-sparing treatment that is effective against diverse enterococcal isolates, including vancomycin-resistant enterococci, during catheter-associated urinary tract infections.

Urinary Tract Infections (UTI), and their complications, cause serious health problems, which affect millions of people every year. Infections of the urinary tract are the second most common type of infection in the body and approximately 20% of women are especially prone to UTIs for reasons not yet well understood. Urinary Tract Infections in men are not as common as in women yet can be very serious when they do occur. Accurate identification of bacterial isolates is an essential task of the clinical microbiology laboratory. The purpose of this study was to determine the incidence and variety of the causative microbial agents of UTIs in patients who had referred to a medical laboratory of Kashani and Hajar hospital in Shahrekord, Iran. In this cross-sectional study 147 urine samples of patients (urine test results were positive for UTIs) were examined during April to September 2013. A total of 147 urine samples of patients with clinical symptoms of UTI who had been referred to a medical laboratory of Kashani and Hajar hospital in Shahrekord (Iran), were collected and processed immediately for laboratory analysis. Escherichia coli was identified as the most common causative agent of UTIs (51.70% of total isolates in both sexes), followed by Klebsiella pneumoniae (K. Pneumoniae) (16.32%). Frequency of Proteus spp., Acinetobacter spp., Entrobacter spp., Citrobacter spp., Pseudomonas aeruginosa (P. aeruginosa) and Providencia spp. was 10.88%, 6.12%, 5.44%, 4.08%, 3.40% and 2.04%, respectively. Statistical analysis by Fisher exact test showed that there was no significant relationship between the type of bacteria and gender (P > 0.05). Chi square test showed that there was no significant relationship between the type of bacteria and the use of catheter and age group (P > 0.05). However, there was a significant relationship between the type of bacteria and the history of hospitalization (P > 0.05). Our findings implied that a wide range of bacteria could be involved in creating urinary tract infection in patients referred to a medical laboratory of Kashani and Hajar hospital in Shahrekord, Iran. Regardless of age, sex and the use of catheter, a wide range of bacteria could be involved in urinary tract infections.

Diabetes mellitus (DM) has become an epidemic, causing a significant decline in quality of life of individuals due to its multisystem involvement. Kidney is an important target organ in DM accounting for the majority of patients requiring renal replacement therapy at dialysis units. Microalbuminuria (MA) has been a valuable tool to predict end-organ damage in DM but its low sensitivity has driven research efforts to seek other alternatives. Albumin is taken up by albumin receptors, megalin and cubilin in the proximal tubule epithelial cells. We demonstrated that insulin at physiological concentrations induce albumin endocytosis through activation of protein kinase B (Akt) in proximal tubule epithelial cells. Inhibition of Akt by a phosphorylation deficient construct abrogated insulin induced albumin endocytosis suggesting a role for Akt in insulin-induced albumin endocytosis. Furthermore we demonstrated a novel interaction between Akt substrate 160kDa (AS160) and cytoplasmic tail of megalin. Mice with type 1 DM (T1D) displayed decreased Akt, megalin, cubilin and AS160 expression in their kidneys in association with urinary cubilin shedding preceding significant MA. Patients with T1D who have developed MA in the EDC (The Pittsburgh Epidemiology of Diabetes Complications) study demonstrated urinary cubilin shedding prior to development of MA. We hypothesize that perturbed insulin-Akt cascade in DM leads to alterations in trafficking of megalin and cubilin, which results in urinary cubilin shedding as a prelude to MA in early diabetic nephropathy. We propose that utilization of urinary cubilin shedding, as a urinary biomarker, will allow us to detect and intervene in diabetic nephropathy (DN) at an earlier stage. PMID:26465605

Zinc uptake contributes to motility and provides a competitive advantage to Proteus mirabilis during experimental urinary tract infection.

Proteus mirabilis, a Gram-negative bacterium, represents a common cause of complicated urinary tract infections in catheterized patients or those with functional or anatomical abnormalities of the urinary tract. ZnuB, the membrane component of the high-affinity zinc (Zn(2+)) transport system ZnuACB, was previously shown to be recognized by sera from infected mice. Since this system has been shown to contribute to virulence in other pathogens, its role in Proteus mirabilis was investigated by constructing a strain with an insertionally interrupted copy of znuC. The znuC::Kan mutant was more sensitive to zinc limitation than the wild type, was outcompeted by the wild type in minimal medium, displayed reduced swimming and swarming motility, and produced less flaA transcript and flagellin protein. The production of flagellin and swarming motility were restored by complementation with znuCB in trans. Swarming motility was also restored by the addition of Zn(2+) to the agar prior to inoculation; the addition of Fe(2+) to the agar also partially restored the swarming motility of the znuC::Kan strain, but the addition of Co(2+), Cu(2+), or Ni(2+) did not. ZnuC contributes to but is not required for virulence in the urinary tract; the znuC::Kan strain was outcompeted by the wild type during a cochallenge experiment but was able to colonize mice to levels similar to the wild-type level during independent challenge. Since we demonstrated a role for ZnuC in zinc transport, we hypothesize that there is limited zinc present in the urinary tract and P. mirabilis must scavenge this ion to colonize and persist in the host.

Diabetic nephropathy (DN) is one of the major complications of diabetes mellitus (DM), leads to chronic kidney disease (CKD), and, ultimately, is the main cause for end-stage kidney disease (ESKD). Beyond urinary albumin, no reliable biomarkers are available for accurate early diagnostics. Urinary extracellular vesicles (UEVs) have recently emerged as an interesting source of diagnostic and prognostic disease biomarkers. Here we used a protease and respective protease inhibitor array to profile urines of type 1 diabetes patients at different stages of kidney involvement. Urine samples were divided into groups based on the level of albuminuria and UEVs isolated by hydrostatic dialysis and screened for relative changes of 34 different proteases and 32 protease inhibitors, respectively. Interestingly, myeloblastin and its natural inhibitor elafin showed an increase in the normo- and microalbuminuric groups. Similarly, a characteristic pattern was observed in the array of protease inhibitors, with a marked increase of cystatin B, natural inhibitor of cathepsins L, H, and B as well as of neutrophil gelatinase-associated Lipocalin (NGAL) in the normoalbuminuric group. This study shows for the first time the distinctive alterations in comprehensive protease profiles of UEVs in diabetic nephropathy and uncovers intriguing mechanistic, prognostic, and diagnostic features of kidney damage in diabetes.

The urinary tract is a common site of infection in humans. During pregnancy, urinary tract infection (UTI) is associated with increased risks of maternal and neonatal morbidity and mortality, even when the infection is asymptomatic. By mapping available rates of UTI in pregnancy across different populations, we emphasize this as a problem of global significance. Many countries with high rates of preterm birth and neonatal mortality also have rates of UTI in pregnancy that exceed rates seen in more developed countries. A global analysis of the etiologies of UTI revealed familiar culprits as well as emerging threats. Screening and treatment of UTI have improved birth outcomes in several more developed countries and would likely improve maternal and neonatal health worldwide. However, challenges of implementation in resource-poor settings must be overcome. We review the nature of the barriers occurring at each step of the screening and treatment pipeline and highlight steps necessary to overcome these obstacles. It is our hope that the information compiled here will increase awareness of the global significance of UTI in maternal and neonatal health and embolden governments, nongovernmental organizations, and researchers to do their part to make urine screening and UTI treatment a reality for all pregnant women.

Background and Objectives: Our objective is to report intermediate-term outcomes for patients who have undergone upper tract urologic laparoendoscopic single-site surgery (LESS) at a single institution. Methods: From January 1, 2008, through November 30, 2012, 107 cases treated with LESS were identified, including pyeloplasty (n = 30), ureterolithotomy (n = 32), nephrectomy (n = 35; simple = 31, partial = 4), and cyst decortication (n = 10). Perioperative data were reviewed, and conversion and complication rates were noted. Results: The median follow-up was 21.5 months for pyeloplasty, 20.5 for ureterolithotomy, 28.0 for simple nephrectomy, 14.0 for partial nephrectomy, and 19.0 for cyst decortication. Major complications were encountered in 8 patients, including 3 intraoperative complications (2 bowel injury with serosal tearing and 1 intraoperative bleeding), which were recognized and repaired with LESS or conversion to conventional laparoscopy (CL). During the intermediate postoperative period (30–90 days) major complications occurred in 5 patients: 4 ureteral strictures (Clavien-Dindo grade [CG] IIIb) and 1 urinoma formation (CG IIIa). During the early postoperative period (<30 days), the most common minor complications were flank pain (CG I) in 16 patients and urinary tract infection (CG II) in 11, followed by urinary leakage (CG I) in 8. Conclusions: Intermediate-term functional outcomes of this single-center study confirm that upper tract LESS is a challenging procedure that can be safe and effective when performed by an experienced team. Prospective studies with longer follow-up periods are needed to investigate the safety of LESS in the treatment of various upper urinary tract conditions. PMID:26648679

Reconstructive urologists are constantly facing diverse and complex pathologies that require structural and functional restoration of urinary organs. There is always a demand for a biocompatible material to repair or substitute the urinary tract instead of using patient’s autologous tissues with its associated morbidity. Biomimetic approaches are tissue-engineering tactics aiming to tailor the material physical and biological properties to behave physiologically similar to the urinary system. This review highlights the different strategies to mimic urinary tissues including modifications in structure, surface chemistry, and cellular response of a range of biological and synthetic materials. The article also outlines the measures to minimize infectious complications, which might lead to graft failure. Relevant experimental and preclinical studies are discussed, as well as promising biomimetic approaches such as three-dimensional bioprinting. PMID:28546955

The biopsies of prostate are the reference examination to assert the diagnosis of prostate cancer. Even if the urinary infectious complications are rare thanks to the systematic oral antibiotic prophylaxis, they may still be serious. The SPILF (Society of Infectious Pathology and French language) published in 2014, an important increase of the resistances in fluoroquinolones for Escherichia coli (3 to 25%), whereas this is the most bacterium frequently found in the urinary infections (70-80%). The objectives of this study were to estimate the indicence of the febrile urinary tract infections after prostate needle biopsy and to define the ecology and the profile of E. coli's resistance. A total of 466 transrectal ultrasound-guided needle prostate biopsy were included in the study from 2012 to 2015. All the patients were taken care according to the recommendations of the AFU (Ouzzane et al., 2011). We estimated, for all the inclusive patients, if they had presented a clinic sign of urinary infection like fever or burning which suggestive of an urinary infection, and having a urines and blood culture, in the next 30 days the realization of the medical exam. Among 466 realized biopsies, seven patients developed a febril urinary tract infection (1.5%) [prostatitis (n=6), orchitis (n=1)]. Five infections to E. coli were identified; two were resistant for fluoroquinolones (40%). No germ was able to be identified for two patients. The infectious complications post-biopsy of prostate are rare (1.5%). E. coli is the germ most frequently identified with 40% of resistance with fluoroquinolones. 4.

Sacral anterior root stimulation (SARS) and posterior sacral rhizotomy restores the ability to urinate on demand with low residual volumes, which is a key for preventing urinary complications that account for 10% of the causes of death in patients with spinal cord injury with a neurogenic bladder. Nevertheless, comparative cost-effectiveness results on a long time horizon are lacking to adequately inform decisions of reimbursement. This study aimed to estimate the long-term cost-utility of SARS using the Finetech-Brindley device compared with medical treatment (anticholinergics+catheterization). The following study design is used for the paper: Markov model elaborated with a 10-year time horizon; with four irreversible states: (1) initial treatment, (2) year 1 of surgery for urinary complication, (3) year >1 of surgery for urinary complication, and (4) death; and reversible states: urinary calculi; Finetech-Brindley device failures. The sample consisted of theoretical cohorts of patients with a complete spinal cord lesion since ≥1 year, and a neurogenic bladder. Effectiveness was expressed as quality adjusted life years (QALYs). Costs were valued in EUR 2013 in the perspective of the French health system. A systematic review and meta-analyses were performed to estimate transition probabilities and QALYs. Costs were estimated from the literature, and through simulations using the 2013 French prospective payment system classification. Probabilistic analyses were conducted to handle parameter uncertainty. In the base case analysis (2.5% discount rate), the cost-utility ratio was 12,710 EUR per QALY gained. At a threshold of 30,000 EUR per QALY the probability of SARS being cost-effective compared with medical treatment was 60%. If the French Healthcare System reimbursed SARS for 80 patients per year during 10 years (anticipated target population), the expected incremental net health benefit would be 174 QALYs, and the expected value of perfect information (EVPI) would be 4.735 million EUR. The highest partial EVPI is reached for utility values and costs (1.3-1.6 million EUR). Our model shows that SARS using Finetech-Brindley device offers the most important benefit and should be considered cost-effective at a cost-effectiveness threshold of 30,000 EUR per QALY. Despite a high uncertainty, EVPI and partial EVPI may indicate that further research would not be profitable to inform decision-making. Copyright © 2015 Elsevier Inc. All rights reserved.

Urinary tract infections during pregnancy.

2004-10-01

To provide a comprehensive review of urinary tract infections (UTIs) during pregnancy. All aspects of UTIs, including epidemiology, pathogenesis, resistance, clinical features, diagnosis, treatment, and prevention, were reviewed. MEDLINE (1966-August 2003) and Cochrane Library searches were performed using the key search terms urinary tract infection, pyelonephritis, cystitis, asymptomatic bacteriuria, and resistance. All article abstracts were evaluated for relevance. Only articles pertaining to pregnancy were included. The majority of published literature were review articles; the number of original clinical studies was limited. UTIs are the most common bacterial infections during pregnancy. They are characterized by the presence of significant bacteria anywhere along the urinary tract. Pyelonephritis is the most common severe bacterial infection that can lead to perinatal and maternal complications including premature delivery, infants with low birth weight, fetal mortality, preeclampsia, pregnancy-induced hypertension, anemia, thrombocytopenia, and transient renal insufficiency. Enterobacteriaceae account for 90% of UTIs. The common antibiotics used are nitrofurantoin, cefazolin, cephalexin, ceftriaxone, and gentamicin. Therapeutic management of UTIs in pregnancy requires proper diagnostic workup and thorough understanding of antimicrobial agents to optimize maternal outcome, ensure safety to the fetus, and prevent complications that lead to significant morbidity and mortality in both the fetus and the mother.

Persistence of urinary incontinence post acquired brain injury (ABI) carries important prognostic significance. We undertook to document the incidence of urinary incontinence, its management and complications in rehabilitation inpatients following ABI and to assess adherence to post ABI bladder management guidelines. A retrospective chart survey of a convenience sample of consecutive admissions to two adult neurorehabilitation units Forster Green Hospital, Belfast, and the Scottish Brain Injury Rehabilitation Service, Edinburgh (SBIRSE). Bladder continence and management on transfer to and discharge from rehabilitation, trial removal of catheter, use of bladder drill, ultrasound investigation, anticholinergic medication and complications were recorded. One hundred and forty six patients were identified. Seventy-seven (52.7%) were independent and continent of urine at rehabilitation admission and 109 (74.7%) on discharge. In all, 13 patients had urinary tract infection, 7 had urethral stricture and 1 developed haematuria whilst catheterised. Ultrasound of renal tracts was underused. Trial removal of catheter after transfer to rehabilitation occurred at a median of 10 days. Urinary continence was achieved in almost half of incontinent ABI patients during rehabilitation. There is potential for increased use of investigation of the renal tracts. Rehabilitation physicians should consider urethral stricture in the management of continence post ABI.

Urinary tract infection (UTI) is the most common disorder caused by bacterial agents in pregnancy, which can lead to important complications in newborn of such mothers in case of inappropriate diagnosis and treatment. The purpose of this study was to study the prevalence of UTI among pregnant women and its complications in their newborns during the birth in the hospitals of Dezful City, Iran, during 2012 - 2013. In this cross-sectional retrospective study, 1132 women admitted to Dr. Ganjavian and Ayatollah Nabavi Hospitals in Dezful City, Iran, during 2012 - 2013 were randomly allocated into the case and control groups and were matched based on their age, numbers of pregnancy, sex and diseases of their children. UTI was the only difference between the two groups. Twenty-two thousand six hundred deliveries occurred within the course of this study. Due to UTI, 5% of deliveries led to hospitalization of mothers (1132 patients).Weight and height of newborn infants of mothers afflicted with UTI (P < 0.001) were significantly lower compared to newborns of healthy women (P < 0.001). There was a significant association between the two groups of pregnant women with UTI in terms of type of delivery (normal and caesarean section) (P < 0.008). The lower incidence of UTI in pregnant women compared to other areas of Iran represents the role of climate and weather in the prevalence of UTI. In addition, the increased number of low-birth-weight infants had a remarkable correlation with UTI, which can influence the health of the next generation.

2007-09-15

Background. Ureterointestinal anastomotic strictures (UAS) complicate 10-15% of surgeries for urinary diversion and are the main cause of deterioration in renal function. Treatments are surgical revision, management with autostatic stent, balloon dilatation, endoscopic incision, and percutaneous transrenal diathermy (Acucise). A new option is cryoplastic dilatation (Polar-Cath). Purpose. To assess the feasibility, complications, and preliminary results of UAS treatment using the Acucise and Polar-Cath systems. Methods. Nineteen UAS, diagnosed by ultrasonography or computed tomography and sequential renal scintigraphy, occurred in 15 cancer patients after radical cystectomy and urinary diversion. Fifteen were managed with balloon diathermy and 4 by balloon cryoplasty inmore » a three-stage procedure-percutaneous nephrostomy, diathermal or cryoplastic dilatation, and transnephrostomic control with nephrostomy removal-each separated by 15 days. All patients gave written informed consent. Results. Dilatations were successful in all cases. The procedure is simple and rapid (about 45 min) under fluoroscopic control and sedation. Procedural complications occurred in 1 (5%) patient with UAS after Wallace II uretero-ileocutaneostomy: a common iliac artery lesion was induced by diathermal dilatation, evident subsequently, and required surgical repair. Patency with balloon diathermy was good, with two restenoses developing over 12 months (range 1-22) of follow-up. With balloon cryoplastic dilatation, one restenosis developed in the short term; follow-up is too brief to assess the long-term efficacy. Conclusion. Our short-term results with diathermal and cryoplastic dilatation to resolve UAS are good. If supported by longer follow-up, the techniques may be considered as first-choice approaches to UAS. Surgery should be reserved for cases in which this minimally invasive technique fails.« less

There is growing concern that the quality of inpatient care may differ on weekends versus weekdays. We assessed the "weekend effect" in common urgent general operative procedures. The Healthcare Cost and Utilization Project Florida State Inpatient Database (2007-2010) was queried to identify inpatient stays with urgent or emergent admissions and surgery on the same day. Included were patients undergoing appendectomy, cholecystectomy for acute cholecystitis, and hernia repair for obstructed/gangrenous hernia. Outcomes included duration of stay, inpatient mortality, hospital-adjusted charges, and postoperative complications. Controlling for hospital and patient characteristics and type of surgery, we used multilevel mixed-effects regression modeling to examine associations between patient outcomes and admissions day (weekend vs weekday). A total of 80,861 same-day surgeries were identified, of which 19,078 (23.6%) occurred during the weekend. Patients operated on during the weekend had greater charges by $185 (P < .05), rates of wound complications (odds ratio [OR] 1.29, 95% confidence interval [95% CI] 1.05-1.58; P < .05), and urinary tract infection (OR 1.39, 95% CI 1.05-1.85; P < .05). Patients undergoing appendectomy had greater rates of transfusion (OR 1.43, 95% CI 1.09-1.87; P = .01), wound complications (OR 1.32, 95% CI 1.04-1.68; P < .05), urinary tract infection (OR 1.76, 95% CI 1.17-2.67; P < .01), and pneumonia (OR 1.41, 95% CI 1.05-1.88; P < .05). Patients undergoing cholecystectomy had a greater duration of stay (P = .001) and greater charges (P = .003). Patients undergoing weekend surgery for common, urgent general operations are at risk for increased postoperative complications, duration of stay, and hospital charges. Because the cause of the "weekend effect" is still unknown, future studies should focus on elucidating the characteristics that may overcome this disparity. Copyright © 2015 Elsevier Inc.

Judy, Carter E; Galuppo, Larry D

2002-01-01

To describe a technique for endoscope-assisted disruption and removal of urinary calculi using a holmium:YAG laser in sedated, standing horses. Retrospective study. Six horses with urinary calculi. A holmium:YAG laser was used to disrupt naturally occurring urinary calculi in horses (4 geldings, 1 stallion, 1 mare). Ischial urethrotomy was performed in male horses to provide a portal for the endoscope and laser fiber. Calculus fragments were removed by a combination of lavage, transendoscopic basket snare removal, forceps, and digital manipulation. Ischial urethrotomies healed by second intention. Follow-up was obtained by recheck examination and telephone interview of owners. No major operative or postoperative complications occurred. Two calculi (1 stallion and 1 mare) were fragmented by a combination of laser ablation and manual disruption with a lithotrite. Postoperative dysuria occurred in the mare, but resolved after 1 month. Mean (+/- SD) follow-up was 306 +/- 149 days; no other complications were reported. Calcium carbonate urinary calculi (up to 15 cm in diameter) in horses can be effectively fragmented with a holmium:YAG laser. It is not known if this technique would be completely effective for larger calculi or extremely dense calculi. Calculus disruption by an endoscopically assisted holmium:YAG laser offers a minimally invasive method that can be performed in standing horses and that minimizes patient risk.

Complications related to inflatable penile prosthesis (IPP) and artificial urinary sphincter (AUS) reservoirs are rare, potentially life threatening, and poorly described in the literature. As more devices are implanted, the incidence of reservoir-related complications may increase, and it will be important to recognize the relevant signs and symptoms. We present a case series of reservoir-related complications presenting to our institution for treatment. We also reviewed all accounts of reservoir-related complications within the urologic literature. Three cases of reservoir-related complications are presented. Case 1 involves erosion of an intact AUS reservoir into the cecum of a patient with a history of myelomeningocele and bladder augmentation. Case 2 involves an IPP reservoir causing vascular compression, resulting in open exploration and repositioning of the reservoir. Case 3 involves intraperitoneal migration of a retained IPP reservoir to a subhepatic area, which was then removed laparoscopically. Literature review yielded descriptions of eight cases of intestinal complications, five cases of vascular complications, but zero reports of migration to a subhepatic area. Other notable complications include 20 reported cases of reservoir erosion into the bladder and inguinal herniation of the reservoir. Complications involving urologic prosthesis reservoirs, although rare, can have serious implications for patients. A high index of suspicion and familiarity with treatment options is required in order to allow timely diagnosis and appropriate treatment. Patients with prior major abdominal surgeries seem to be more prone to intestinal complications of reservoirs and warrant special concern. Cui T, Terlecki R, and Mirzazadeh M.

Treatment modalities for rectal cancer, including radiation, are associated with urinary adverse effects. The purpose of this study was to determine the influence of surgery and radiation therapy for rectal cancer on long-term urinary complications. Using the Surveillance Epidemiology and End Results-Medicare data set from the United States, patients with rectal cancer older than 66 years of age who underwent rectal resection between 1992 and 2007 were stratified into treatment groups that accounted for surgical resection and the timing of radiation therapy, if used. A control group of patients who did not have rectal cancer were matched by age, sex, demographics, and comorbidities. The primary outcome was a urinary adverse event defined as a relevant urinary diagnosis with an associated procedure. Patients with rectal cancer in different treatment groups were compared with control patients using a propensity-adjusted, multivariable Cox regression analysis. The study was conducted with the Surveillance Epidemiology and End Results-Medicare data set from the United States at our institution. Of the 11,068 patients with rectal cancer, 56.2% had surgical resection alone, 21.7% received preoperative radiation, and 22.1% received postoperative radiation. The median follow-up for all of the groups of patients was >2 years. All of the groups of patients with rectal cancer were more likely to develop a urinary adverse event compared with control subjects. Adjusted HRs were 2.28 (95% CI, 2.02-2.57) for abdominoperineal resection alone, 2.24 (95% CI, 1.79-2.80) for preoperative radiation and surgical resection, 2.04 (95% CI, 1.70-2.44) for surgical resection and postoperative radiation, and 1.69 (95% CI, 1.52-1.89) for low anterior resection alone. Treatment patterns are somewhat outdated, with a large proportion of patients receiving postoperative radiation. The data did not allow for accurate assessment of urinary tract infections or mild urinary retention that is not managed with a procedure. Rectal cancer surgery with or without radiation is associated with a higher risk of urinary complications requiring procedures. Patients who undergo low anterior resection without radiation tend toward the lowest risk for a urinary adverse event.

Urinary Tract Infection implies presence of actively multiplying organisms in the urinary tract. Although it is infrequently associated with mortality, it is still a significant cause of morbidity. Early diagnosis is critical to preserve renal function of growing kidney. Our purpose was to determine the clinical, microbiologic profile and antibiotic sensitivity of such infections in pediatric Urinary Tract Infection (UTI) patients at Dhulikhel Hospital. A hospital based prospective descriptive study of 135 children from 2 months to 16 years, with clinical diagnosis of urinary tract infection who visited the pediatric department of Dhulikhel Hospital over the period of 15 months were enrolled in the study. All patients underwent routine urine analysis and culture. Children with recurrent UTI underwent micturating cystourethrogram (MCUG). Children with recurrent UTI of more than two years and with feature of pyelonephritis underwent USG abdomen as well. Complications and response of the treatment was observed in all cases of UTI. All data were entered in Epidata and data analysis was done using spss 16 version. Among 135 children, 32.5% were male and 67.4% were female. Fever was the most common presenting symptom in 74.80% of patients followed by dysuria in 54.1%. Among these children 95.6% had significant pyuria and 45% had culture positive infection. Children who showed positive for bacteriuria, Escherichia coli (78.7%) was the most common organism and are more than 80% sensitive to Amikacin, Gentamicin, Ceftriaxone, Ofloxacin, Nalidixic acid, Imipenem and Vancomycin. Co-trimoxazole was the most common drug used for treatment with a mean drug respond time of (mean+/-S.D) of 2.21+/-.78 days. 2+/-. Children who had recurrent UTI were more prone to develop culture positive UTI (p=0.0001). Urinary Tract Infection in female was almost twice more common than in male. Cotrimoxazole was the most common drug used for treatment, sensitivity of this drug was less than 50% for all organisms.

Biliary obstruction, a severe cholestatic complication, causes accumulation of toxic bile acids (BAs) in liver cells. Glucuronidation, catalyzed by UDP-glucuronosyltransferase (UGT) enzymes, detoxifies cholestatic BAs. Using liquid chromatography coupled to tandem mass spectrometry, 11 BA glucuronide (-G) species were quantified in prebiliary and postbiliary stenting serum and urine samples from 17 patients with biliary obstruction. Stenting caused glucuronide- and fluid-specific changes in BA-G levels and BA-G/BA metabolic ratios. In vitro glucuronidation assays with human liver and kidney microsomes revealed that even if renal enzymes generally displayed lower K M values, the two tissues shared similar glucuronidation capacities for BAs. By contrast, major differences between the two tissues were observed when four human BA-conjugating UGTs 1A3, 1A4, 2B4, and 2B7 were analyzed for mRNA and protein levels. Notably, the BA-24G producing UGT1A3 enzyme, abundant in the liver, was not detected in kidney microsomes. In conclusion, the circulating and urinary BA-G profiles are hugely impacted under severe cholestasis. The similar BA-glucuronidating abilities of hepatic and renal extracts suggest that both the liver and kidney may contribute to the urine BA-G pool.

The outcome of patients with urinary tract infections caused by extended spectrum β-lactamases (ESBL)-producing bacteria (cases) was compared with that of matched controls with urinary tract infections caused by non-extended spectrum β-lactamases-producing isolates. Significantly, more case patients received inappropriate empiric therapy than controls. Nevertheless, clinical and microbiologic outcomes as well as formation of renal scars did not differ between the 2 groups.

[The role of the uretral catheter in the development of catheter- related urinary tract infection].

PubMed

The most common source of nosocomial infection is the urinary tract, especially if they it is drained with a urethral catheter. Catheter-associated urinary tract infections account for at least 80% of all complicated urinary tract infections and are the most common type of hospital-acquired infection. Intestinal microflora plays the leading role in the pathogenesis of catheter-associated urinary tract infections, whereas the most important risk factor for their development is the long duration of urinary catheter drainage. In the case of short-term and intermittent catheterization, routine antibiotic prophylaxis is not required, but if a patient develops clinically significant infection, antibiotic therapy is required followed by definitive therapy based on culture. Urethral catheters coated with antimicrobial substances and anti-inflammatory agents can significantly reduce the adhesion and migration of bacteria, thereby reducing the incidence of urinary tract infections. Despite this, the incidence of catheter-associated infection remains high. We have reviewed recent literature related to catheter-associated urinary tract infections and the best means of preventing this condition.

The failure of empirical therapy is frequently observed, even in community-acquired urinary tract infections. We, therefore, conducted a prospective, clinic-based study in 2004-2005 to document anti-microbial resistance rates and correlate them with possible risk factors to assist empirical decision-making. Symptomatic patients with pyuria underwent urine culture. Isolates were identified using standard methods and anti-microbial resistance was determined by disk-diffusion. Ultrasonography was used to detect complicating factors. Patients were stratified by the presence of complicating factors and history of invasive procedures for comparison of resistance rates. STATISTICAL METHOD USED: Chi-square or Fisher exact tests, as appropriate. There were 156 E. coli isolates, of which 105 were community-acquired. Twenty-three community-acquired isolates were from patients with complicating factors while 82 were from patients without any. Fifty-one isolates were from patients who had recently undergone invasive procedures on the urinary tract. Thirty-two community-acquired isolates from reproductive-age women without apparent complicating factors had resistance rates of 50% or above against tetracyclines, Co-trimoxazole, aminopenicillins, Nalidixic acid, Ciprofloxacin and 1 st generation cephalosporins. Resistance rates were significantly higher among isolates from patients subjected to invasive procedures, except against Co-trimoxazole, tetracyclines and Amikacin. High rates of anti-microbial resistance in community-acquired uropathogens have made antimicrobial sensitivity testing necessary even in a rural, primary-care setting.

Diagnosis and management of urinary tract infections in the emergency department.

Urinary tract infections are a heterogeneous group of disorders, involving infection of all or part of the urinary tract, and are defined by bacteria in the urine with clinical symptoms that may be acute or chronic. Approximately 1 million urinary tract infections are treated every year in United States emergency departments. The female-to-male ratio is 6:1. Urinary tract infections are categorized as upper versus lower tract involvement and as uncomplicated versus complicated. The emergency clinician must carefully categorize the infection and take into account patient host factors to optimally treat and disposition patients. A working knowledge of local or at least national susceptibility patterns of the most likely pathogens is essential. A variety of special populations exist that require special management, including pregnant females, patients with anatomic abnormalities, and instrumented patients.

Internal fixation in pelvic fractures and primary repairs of associated genitourinary disruptions: a team approach.

Associated urological and orthopedic injuries of the pelvic ring are complex with numerous potential complications. These patients are treated optimally using a team approach. The combined expertise is not only helpful initially when managing these difficult patients, but also later as problems develop. This study describes a treatment protocol and reports the early results of 23 patients with unstable pelvic fractures and associated bladder or urethral disruptions, or both, treated surgically with open reduction and internal fixation of the anterior pelvic ring injuries at the same anesthetic and using the same surgical exposure as the urethral realignments or bladder repairs or both. Early complications occurred in four patients (17%): one patient sustained a fifth lumbar nerve injury caused by the pelvic reduction procedure, and three patients had anterior pelvic internal fixation failures. Late complications occurred in eight patients (35%). There was one deep wound infection (4.3%) that presented 6 weeks after injury. Late urological complications occurred in seven patients (30%). Four of the nine male patients with urethral disruptions had urethral stricture after their primary urethral realignments (44%). Three of the 18 male patients admitted to impotence (16.7%). One of the three had a residual thoracic paraplegia caused by a burst fracture. One of the five female patients had urinary incontinence and required a bladder suspension operation to restore normal function (20%). A low infection rate can be expected despite the use of internal fixation. Early urethral "indirect" realignments avoid more difficult delayed open repairs; however, late urological complication rates are still high. Early "direct" bladder repairs are easily performed at the time of anterior pelvic open reduction and internal fixation. Suprapubic tubes are not necessary to adequately divert the urine when large diameter urethral catheters are used in these patients.

Herpes zoster is caused by the infection of Varicella-Zoster virus. The anatomical distribution of herpes zoster in the sacral area is only 6. 9%1). Moreover, the onset rate of herpes zoster with urinary dysfunction is 0.6%1). The lesion sites of herpes zoster which cause urinary dysfunction are almost lumber and sacral areas. We describe four cases of sacral herpes zoster with urinary dysfunction in this report. All patients were elderly people (66-84 years old), and all patients were administered anti-virus drugs and alpha 1-adrenergic receptor blockers. Because of urinary retention, three patients have performed clean intermittent self-catheterization (CIC) for several weeks. As the lesions of herpes zoster healed, each patient recovered from urinary dysfunction.

To determine the safety and efficacy of advanced electrothermal bipolar vessel sealing (EBVS) during vaginal hysterectomy by evaluating urinary complications, overall complications, and reoperation rate. A retrospective cohort (Canadian Task Force classification III). High-volume gynecologic surgeon practice, private hospital. One thousand consecutive patients who have undergone vaginal hysterectomy for benign conditions carried out with EBVS between January 2002 and December 2012. Vaginal hysterectomy performed using an EBVS device. One thousand consecutive patients underwent vaginal hysterectomy with advanced EBVS between January 2002 and December 2012 with an average age of 51.4 ± 8.9 years (range, 31-88) and mean weight and body mass index of 57.4 ± 7.2 kg (range, 42-105) and 25.8 ± 4.2 kg/m 2 (range, 19.1-38.9), respectively. Eighty-five percent of patients (852/1000) were healthy without any severe systemic disease. A single experienced surgeon performed all vaginal hysterectomies with EBVS, specifically by not applying traction during thermofusion to avoid hemorrhage, amputating the cervix to transform the uterus to an apple shape to facilitate a vaginal approach and rotation of the uterus, and placing bi-clamp forceps on the edge of the uterus and not at a 45- or 90-degree angle. Wound closure was completed with a continuous suture. Eleven urinary complications (1.1%) were recorded (10 bladder mechanical injuries and 1 vesicovaginal fistula). This was not statistically different from the rate of .64% previously reported in the FINHYST study (p = .15). The overall rate of complications was 5.3%, and 20 patients (2.0%) required reoperation. The presence of uterine scar tissue (odds ratio, 5.5; 95% confidence interval, 1.6-19.2) and larger uterus size (odds ratio, 2.5; 95% confidence interval, 1.01-19.2) were associated with a higher risk of urinary complications. The use of EBVS during vaginal hysterectomy results in urinary and overall complication rates of 1.1% and 5.3%, respectively, statistically similar to previously reported series that did not use EBVS. The use of advanced EBVS is a safe and effective method of achieving hemostasis during vaginal hysterectomy. Copyright © 2016 AAGL. Published by Elsevier Inc. All rights reserved.

Complications of hip fractures: A review

Carpintero, Pedro; Caeiro, Jose Ramón; Carpintero, Rocío; Morales, Angela; Silva, Samuel; Mesa, Manuel

2014-01-01

Nowadays, fracture surgery represents a big part of the orthopedic surgeon workload, and usually has associated major clinical and social cost implications. These fractures have several complications. Some of these are medical, and other related to the surgical treatment itself. Medical complications may affect around 20% of patients with hip fracture. Cognitive and neurological alterations, cardiopulmonary affections (alone or combined), venous thromboembolism, gastrointestinal tract bleeding, urinary tract complications, perioperative anemia, electrolytic and metabolic disorders, and pressure scars are the most important medical complications after hip surgery in terms of frequency, increase of length of stay and perioperative mortality. Complications arising from hip fracture surgery are fairly common, and vary depending on whether the fracture is intracapsular or extracapsular. The main problems in intracapsular fractures are biological: vascularization of the femoral head, and lack of periosteum -a major contributor to fracture healing- in the femoral neck. In extracapsular fractures, by contrast, the problem is mechanical, and relates to load-bearing. Early surgical fixation, the role of anti-thromboembolic and anti-infective prophylaxis, good pain control at the perioperative, detection and management of delirium, correct urinary tract management, avoidance of malnutrition, vitamin D supplementation, osteoporosis treatment and advancement of early mobilization to improve functional recovery and falls prevention are basic recommendations for an optimal maintenance of hip fractured patients.

Catheterization and urinary tract infections: microbiology.

PubMed

Godfrey, H; Evans, A

Patients with urinary catheters are a substantial proportion of the total patient population and catheter care is an important area of nursing practice. Urinary tract infection associated with catheterization is known to be the most common nosocomial (hospital-acquired) infection. Urinary tract infections can be caused by exogenous microorganisms or endogenous faecal or urethral microorganisms. The different microorganisms which are responsible for causing urinary tract infections have particular characteristics. Many microorganisms form a biofilm, a living layer of cells which stick to the surfaces of the catheter and the catheter bag. Biofilms not only lead to urinary tract infections, but also they are associated with encrustation and catheter blockage. The article considers the microorganisms implicated in catheter-associated urinary tract infections and aims to develop an increased awareness of the characteristics of different pathogens which could lead to enhanced nursing practice and improved patient care.

Community-acquired urinary tract infection (UTI) caused by extended-spectrum beta-lactamase (ESBL)-producing Escherichia coli is an emerging problem. Compared with urban infants, rural infants may encounter different distributions of community-acquired resistant strains and various barriers to efficient management. A retrospective survey and comparison was conducted for infants with UTI caused by ESBL-producing E. coli admitted to an urban hospital (n = 111) and a rural hospital (n = 48) in southern Taiwan from 2009 to 2012. Compared with 2009 and 2010, the total number of cases at both hospitals significantly increased in 2011 and 2012 (p < 0.001). Compared with the rural patients, the urban patients were significantly younger, and they had fewer days of fever before and after admission, fewer presentations of poor activity and poor appetite, and a lower serum creatinine level. Most of the patients had no prior history of illness, and we could not identify any significant different risk factors for acquiring ESBL-producing E. coli, such as past antimicrobial use, hospitalization, UTI, and underlying renal diseases, between the urban and rural populations. The increase in community-acquired UTI in infants caused by ESBL-producing E. coli was similar between the urban and rural populations. Our preliminary data suggest that the rural-urban disparities were probably related to easy access to health care by the urban population. ESBL complicates disease management, and the increase in the prevalence of ESBL producers is a major health concern and requires further healthy carrier and environmental surveillance.

The kidney in pregnancy: A journey of three decades.

Prakash, J

2012-05-01

The spectrum of kidney disease occurring during pregnancy includes preeclampsia, hypertensive disorders of pregnancy, urinary tract infection, acute kidney injury, and renal cortical necrosis (RCN). Preeclampsia affects approximately 3-5% of pregnancies. We observed preeclampsia in 5.8% of pregnancies, and 2.38% of our preeclamptic women developed eclampsia. Severe preeclampsia and the eclampsia or hemolysis, elevated liver enzymes levels, and low platelets count (HELLP) syndrome accounted for about 40% of cases of acute kidney injury (AKI) in pregnancy. Preeclampsia/eclampsia was the cause of acute renal failure (ARF) in 38.3% of the cases. Preeclampsia was the most common (91.7%) cause of hypertension during pregnancy, and chronic hypertension was present in 8.3% of patients. We observed urinary tract infection (UTI) in 9% of pregnancies. Sepsis resulting from pyelonephritis can progress to endotoxic shock, disseminated intravascular coagulation, and AKI. The incidence of premature delivery and low birth weight is higher in women with UTI. The incidence of AKI in pregnancy with respect to total ARF cases has decreased over the last 30 years from 25% in 1980s to 5% in 2000s. Septic abortion-related ARF decreased from 9% to 3%. Prevention of unwanted pregnancy and avoidance of septic abortion are key to eliminate abortion-associated ARF in early pregnancy. The two most common causes of ARF in third trimester and postpartum periods were puerperal sepsis and preeclampsia/HELLP syndrome. Pregnancy-associated thrombotic thrombocytopenic purpura/hemolytic uremic syndrome and acute fatty liver of pregnancy were rare causes of ARF. Despite decreasing incidence, AKI remains a serious complication during pregnancy.

Purpose: To evaluate the role of multidetector computed tomography (MDCT) in recognizing the complications of extracorporeal shock wave lithotripsy (ESWL) and providing a prognostic grading system for the therapeutic approach. Materials and Methods: A total of 43 patients who underwent ESWL because of urinary stone disease were assessed by 320-row MDCT examination before and after ESWL. Pre-ESWL CT unenhanced scans were performed for diagnosing stone disease. Post-ESWL CT scans were acquired before and after intravenous injection of contrast medium searching for peri-renal fluid collection or hyper-density, pyelic or ureteral wall thickening, blood clots in the urinary tract, peri- or intra-renal hematoma or abscess, active bleeding. A severity grading system of ESWL complications was established. Results: Patients were affected by renal (n = 36) or ureteral (n = 7) lithiasis. Post-ESWL CT examination detected small fluid collections and hyper-density of peri-renal fat tissue in 35/43 patients (81%), pyelic or ureteral wall thickening in 2/43 (4%), blood clots in the urinary tract in 9/43 (21%), renal abscesses or hematomas with a diameter of <2 cm in 10/43 (23%), large retroperitoneal collections in 3/43 (7%), active bleeding from renal vessels in 1/43 (2%). Mild complications were found in 30 cases; moderate in 9; severe in 4. The therapeutic choice was represented by clinical follow-up (n = 20), clinical and CT follow-up (n = 10), ureteral stenting (n = 9), drainage of large retroperitoneal collections (n = 3), and arterial embolization (n = 1). Conclusion: MDCT plays a crucial role in the diagnosis of urolithiasis and follow-up of patients treated with ESWL recognizing its complications and providing therapeutic and prognostic indications.

To report on the prevalence, surgical management, and outcome of urinary tract endometriosis (UTE) in a cohort of 221 patients undergoing laparoscopic surgery for severe endometriosis. UTE can cause significant morbidity, such as silent kidney or progressive renal function loss. Its frequency is underestimated and data on laparoscopic management are scarce. Between 2007 and 2010, 43 patients were eligible for this single-center, retrospective study. The inclusion criterion was the presence of UTE (ie, bladder and/or ureteral endometriosis). All patients were operated laparoscopically. The prevalence of UTE was 19.5% (43/221). There was no correlation between bladder and ureteral endometriosis (P >.05). Ureteral endometriosis was associated with patient's age (P <.01). Patients with bladder, but not ureteral, involvement complained more frequently about dysuria, hematuria, and urinary tract infections. Intraoperative and magnetic resonance imaging (MRI) findings revealed a moderate to good correlation. UTE was not associated with rectovaginal or bowel endometriosis, but rather with involvement of the uterosacral ligaments (P <.01). Twenty-two patients with bladder endometriosis were treated by mucosal skinning and 11 patients underwent partial cystectomy. Superficial ureteral excision was performed in 4 patients, whereas resection with ureteroureterostomy was done in 9 patients. There was no difference regarding the intra- and postoperative complications in patients with or without UTE. In severe pelvic endometriosis, involvement of the urinary tract is quite common. Laparoscopic management is feasible and safe. Because of the lack of specific symptoms, the preoperative diagnosis of ureteral endometriosis still remains a challenge. Pelvic MRI represents a useful preoperative diagnostic tool. Copyright © 2011 Elsevier Inc. All rights reserved.

We evaluate the safety and efficacy of a new treatment modality for genuine stress urinary incontinence which was a transvaginal radio frequency applicator to deliver radio frequency energy to the endopelvic fascia. The purported mechanism of effect for this therapy is shrinkage of the collagenated tissue which composes the endopelvic fascia that supports the bladder neck and proximal urethra, thus stabilizing the proximal urethra and bladder neck. In prior animal trials and early pilot studies this therapy was shown to cause a reproducible thermal effect manifested by fascial shrinkage. Preliminary human trials indicated a therapeutic benefit of this therapy for women with genuine stress urinary incontinence. To our knowledge this is the first multicenter study of a transvaginal approach for radio frequency of the endopelvic fascia for treatment of genuine stress incontinence. Between June 1999 and June 2000, 120 consecutive women (mean age 49.9 years) at 10 sites underwent transvaginal radio frequency treatment in a prospective trial to evaluate the overall efficacy and safety profile of this therapy. All patients had preoperative urethral hypermobility (average cotton swab change 38 degrees). Detrusor instability was excluded by cystometry. In all procedures precisely controlled radio frequency energy was applied to the endopelvic fascia to heat and shrink the tissue. The patients were evaluated postoperatively at 1 week and at 1, 3, 6 and 12 months using objective and subjective measures. Primary end points consisted of physician assessment of continence, patient reported pad use and the number of patient reported episodes. Safety was determined for acute (immediate postoperative) and chronic time frames. Of the 120 patients 96 completed 1-year evaluation. Average operative time was less than 30 minutes, and all patients were treated as outpatients. Preoperatively 101 patients (84%) averaged 1 or more episodes of urinary incontinence per day. At 3, 6 and 12 months 57%, 66% and 59% of patients, respectively, averaged 1 or no daily episodes of urinary incontinence. At 12-month followup 79 of 109 patients (73%) reported being continent or improved. Preoperatively, 43% of patients reported using 1 or no pads daily. At 3, 6 and 12 months 69%, 70% and 72% of patients, respectively, required 1 or no pads daily. On urodynamic evaluation at 12-month followup 76.0% of the patients did not leak with a Valsalva maneuver. A total of 30 cases were classified as failures and 11 women were lost to followup. There were no intraoperative complications, 3 (4%) minor postoperative complications which resolved, and no device related complications. The transvaginal radio frequency applicator demonstrated good efficacy and excellent safety at 1-year followup. Ongoing analysis of the data has indicated opportunities for improvement of this new surgical technique that could result in higher efficacy rates without compromising safety. Further long-term evaluation is being conducted to assess chronic durability of the procedure.

There is no scientific data on which is the best method and catheter to use in acute urinary retention in males. We therefore compared the efficiency of a size 12 G latex rubber balloon catheter with a similar calibre but more expensive catheter made of polyvinyl-chloride (PVC). A total of 50 patients was studied and a 100% successful catheterisation rate was recorded at first attempt with both catheters, with no significant complications. The importance of the correct management of acute urinary retention, especially adequate analgesia, is stressed and it is concluded that either catheter is satisfactory. PMID:3207328

To explore selection and efficacy assessment for membranous urethral trauma caused by pelvic fracture. From June 2000 to August 2010, 72 patients with membranous urethral trauma caused by pelvic fracture were selected. There were 46 males and 26 females,ranging age from 26 to 62 years (averaged 35.2 years). The time from injury to hospitalization time was 1 to 3 hours. According to Tile pelvic fracture classification, there were 8 patients with type A, 45 patients with type B, 19 patients with type C. Thirty of the 35 patients with partial rupture of posterior urethral were treated by catheterization,5 patients treated by rupture anastomosis on the stage I combined with cystostomy; 25 of the 37 patients with complete rupture of posterior urethra were treated by early realignment, and 12 patients were treated by cystostomy. Urinary incontinence, impotence and urethrostenosis were evaluated. All patients were followed up for 5 to 10 years (mean 7.7 years). Incidence of urethrostenosis, impotence and urinary incontinence in patients treated by cystostomy were significantly higher than rupture anastomosis on the stage I and early realignment (P < 0.05); while incidence in patients treated by catheterization was significantly lower than other groups (P < 0.05). For patients with partial rupture of posterior urethral, catheterization and rupture anastomosis on the stage I are preferred methods; while patients with complete rupture of posterior urethra, early realignment is a preferred method with advantages of simple operation and less complications.

Thioredoxin interacting protein (TXNIP), an inhibitor of antioxidant thioredoxin (Trx), is upregulated by hyperglycemia and implicated in pathogenesis of diabetes complications. We evaluated mRNA expressions of genes encoding TXNIP and Trx (TXN) in urinary sediment and peripheral blood mononuclear cells (PBMC) of type 1 diabetes (T1D) patients with different degrees of chronic complications. qPCR was employed to quantify target genes in urinary sediment (n = 55) and PBMC (n = 161) from patients sorted by presence or absence of diabetic nephropathy (DN), retinopathy, peripheral and cardiovascular neuropathy; 26 healthy controls and 13 patients presenting non-diabetic nephropathy (focal and segmental glomerulosclerosis, FSGS) were also included. Regarding the urinary sediment, TXNIP (but not TXN) expression was higher in T1D (p = 0.0023) and FSGS (p = 0.0027) patients versus controls. Expressions of TXNIP and TXN were higher, respectively, in T1D patients with versus without DN (p = 0.032) and in those with estimated glomerular filtration rate (eGFR) < 60 versus ≥60 mL/min/1.73 m(2) (p = 0.008). eGFR negatively correlated with TXNIP (p = 0.04, r = -0.28) and TXN (p = 0.04, r = -0.30) expressions. T1D patients who lost ≥5 mL/min/1.73 m(2) yearly of eGFR presented higher basal TXNIP expression than those who lost <5 mL/min/1.73 m(2) yearly after median follow-up of 24 months. TXNIP (p < 0.0001) and TXN (p = 0.002) expressions in PBMC of T1D patients were significantly higher than in controls but no differences were observed between patients with or without chronic complications. TXNIP and TXN are upregulated in urinary sediment of T1D patients with diabetic kidney disease (DKD), but only TXNIP expression is associated with magnitude of eGFR decline.

Urinary tract infections (UTI) can cause significant renal scarring, which can be complicated by hypertension and renal impairment. This study describes the outcome of different imaging modalities in children with UTI and its relation to age, sex and type of UTI. Our objective was to describe the frequencies of different imaging studies, which were used to investigate children with UTI at King Fahad Hospital (KFH) between the years 2003 and 2008. This is a descriptive study of all children presenting with UTI at KFH from 2003 to 2008. The study population, 100 children, were divided into 3 age groups; first group (> 1 month to 2 years); second group (> 2 to 5 years), third group (> 5 to 12 years). All enrolled children were confirmed to have had UTI via urinary cultures. Ninety seven (97%) patients underwent renal ultrasonography (US), 77 (77%) had a 99mTc-dimercaptosuccinic acid (DMSA) scan within 2 months of presentation, and 60 (60%) patients underwent micturating cystourethrogram (MCUG), mainly those with an abnormal DMSA scan. A total of 100 patients screened, 10 (10%) were males and 90 (90%) were females, first age group constituted 10%, second age group was 25%, third age groups was 65%. E-coli was isolated in 84% of patients, 60% had recurrent UTI, 45% had pyelonephritis, 48.4% had abnormal renal US, 61% had an abnormal DMSA scan, and 26.6% had abnormal MCUG. UTI can cause significant morbidity in children if not managed properly. Imaging studies are useful in identifying children who require advanced medical intervention; however, such studies should be performed only when indicated. PMID:27493418

To evaluate the related factors of upper urinary tract deterioration in spinal cord injured patients. Medical records of spinal cord injured patients from Jan.2002 to Sep.2009 were retrospectively reviewed. All the patients were divided into the upper urinary tract deterioration group and non-deterioration group according to the diagnostic criteria. Indexes such as demographic characteristic (gender, age), spinal cord injury information (cause, level, completeness), statuses of urinary tract system (bladder management, urine routine, urine culture, ultrasound, serum creatinine, fever caused by urinary tract infection) and urodynamics information(bladder compliance, bladder stability, bladder sensation, detrusor sphincter dyssynergia, detrusor leak point pressure, maximum cystometric capacity, relative safe bladder capacity, maximum flow rate, maximum urethra closure pressure) were compared between the two groups.Then Logistic regression analysis were performed. There was significantly difference between the two groups in spinal cord injury level(χ(2) = 8.840, P = 0.031),bladder management(χ(2) = 11.362, P = 0.045), urinary rutine(χ(2) = 17.983, P = 0.000), fever caused by urinary tract infection(χ(2)= 64.472, P = 0.000), bladder compliance(χ(2) = 6.531, P = 0.011), bladder sensation(χ(2) = 11.505, P = 0.009), maximum cystometric capacity(t = 2.209, P = 0.043), and detrusor-sphincter dyssynergia(χ(2) = 4.247, P = 0.039). The multiple-factor non-conditional Logistic regression analysis showed that bladder management (OR = 1.114, P = 0.006), fever caused by urinary tract infection(OR = 1.018,P = 0.000), bladder compliance (OR = 1.588, P = 0.040) and detrusor-sphincter dyssynergia(OR = 1.023, P = 0.034) were the key factors of upper urinary tract deterioration in spinal cord injured patients. Urinary tract infection, lower bladder compliance, detrusor-sphincter dyssynergia and unreasonable bladder management are the risk factors of upper urinary tract deterioration in spinal cord injured patients.

2014-01-01

Background Untreated asymptomatic bacteriuria (ASB) during pregnancy may cause serious complications including pyelonephritis and delivery of premature or low-birth-weight infants. However, little is known about asymptomatic bacteriuria in pregnancy in Ethiopia. This study aimed to assess the prevalence of asymptomatic bacteriuria, bacterial agents, and their antibiotic susceptibility pattern in pregnant women attending antenatal clinic of the Hawassa Teaching and Referral Hospital. Methods A cross-sectional study was conducted in a total of 244 pregnant women with no sign and symptom of urinary tract infection from March 2012 to September 2012. Clean catch mid-stream urine samples were collected from all study participants using sterile containers. Urine samples were cultured using standard bacteriological methods. Identification of suspected colonies and antibiotic sensitivity testing were done. Result Out of 244 pregnant women, 46(18.8%) were positive for asymptomatic bacteriuria (Colony Forming Unit ≥ 105/mL). There was no difference in prevalence of asymptomatic bacteriuria with respect to age (p = 0.07) and trimester (p = 0.27).The most frequently isolated bacteria were coagulase negative Staphylococcus (32.6%), followed by Escherichia coli (26.1%), and Staphylococcus auerus (13%). The susceptibility rate of bacterial isolate was highest for norfloxacin (64.7%) and lowest for ampicillin (17.6%). Conclusion The high prevalence of ASB in pregnant women warrant the need to screen all pregnant women and treat those infected with appropriate antimicrobial regimens in order to reduce its complications.

Several recent preliminary reports have demonstrated that Robot-Assisted Cystectomy with total intracorporeal Ileal Conduit (RACIC) is a feasible option over the open technique. We report our stepwise surgical procedure of robotic total intracorporeal ileal conduit urinary diversion, technical consideration, development, refinements and initial experience. Only the ileal conduit urinary diversion is described with no emphasis on the cystectomy's steps. Between February 2008 and September 2009, nine patients underwent RACIC for muscle invasive transitional cell carcinoma (TCC). The entire procedure, including radical cystoprostatectomy, extended pelvic node dissection (ePLND), ileal conduit urinary diversion (Bricker) including isolation of the ileal loop (20 cm ileal segment) 15 cm away from the ileocecal junction, restoration of bowel continuity with stapled side-to-side ileo-ileal anastomosis, retroperitoneal transfer of the left ureter to the right side, and bilateral stented (8 F feeding tube) ileo-ureteral anastomoses in a Wallace faction were all performed exclusively intracorporeally using the da Vinci Si surgical robot and finally the conduit stoma was fashioned. The RACIC was technically successful in all nine patients (three females and six males. Mean age 74.1; 57 to 87) without open conversion. The mean operative time including extended pelvic lymphadenectomy and urinary diversion was 346.2 minutes (210 to 480). Mean operative time of diversion is 72 minutes (52-113) mean estimated blood loss 258 mL (200 to 500) and the median hospital stay were 14 days (10 to 27). In all three female patients, the specimen was extracted through the vagina. There were no intraoperative complications and only one major postoperative complication: one postoperative iatrogenous necrosis of the ileal conduit caused by uncareful retraction of the organ bag and thereby probably injuring the conduit pedicle, as the ileal conduit was well vascularised at the end of the operation, requiring an open revision (in male patient extracted through the suprapubic incision). A clear liquid diet was started on the third postoperative day. All patients returned to normal activity within 2 weeks (from date of surgery). Postoperative renal function was normal with mean postoperative creatine 0.99 mg/dL) and excretory urography revealed unobstructed upper tracts in all cases. Robot-assisted radical cystoprostatectomy with intracorporeal ileal conduit urinary diversion for the treatment of high risk or invasive bladder cancer with urinary diversion is technically feasible. The robotic system aids in performing a meticulous dissection and all operative steps of the open procedure are replicated precisely while adhering to the sound oncologic principles of traditional radical cystectomy. Robotics brings an unprecedented control of surgical instruments, shorten the learning curve, and allow open surgeons to apply more easily their technical skill in a minimal invasive fashion. Robotic cystectomy with total intracorporeal ileal conduit urinary diversion offers operative and perioperative benefits and functional outcome. In our hands results comparable to open experience with further reduced perioperative morbidity, early recovery, resumption of normal activities, excellent cosmesis and increased quality of life (QOL). In addition, minimal blood loss, fluid shifts, and electrolyte loss considerably reduce systemic and cardiovascular stress in these older groups of patients.

Sacral root neuromodulation in idiopathic nonobstructive chronic urinary retention.

PubMed

Shaker, H S; Hassouna, M

1998-05-01

Sacral root neuromodulation is becoming a superior alternative to the standard treatment of idiopathic nonobstructive urinary retention. We report results in 20 successive patients who underwent sacral foramen implantation to restore bladder function. After an initial, thorough baseline assessment 20 patients 19.43 to 55.66 years old with idiopathic nonobstructive urinary retention underwent percutaneous nerve evaluation. Response was assessed by a detailed voiding diary. Responders underwent implantation with an S3 foramen implant, and were followed 1, 3 and 6 months postoperatively, and every 6 months thereafter. Sacral root neuromodulation restored voiding capability in these patients. Bladders were emptied with minimal post-void residual urine, which decreased from 78.3 to 5.5 to 10.2% of the total voided volume from baseline to postoperative followup. These results were reflected in uroflowmetry and pressure-flow studies, which were almost normal after implantation. Furthermore, the urinary tract infection rate decreased significantly and associated pelvic pain improved substantially. The Beck depression inventory and SF-36 quality of life questionnaire indicated some improvement but reached significance in only 1 item. In addition, cystometrography showed no significant difference after 6 months of implantation compared with baseline values. Complications were minimal and within expectations. Sacral root neuromodulation is an appealing, successful modality for nonobstructive urinary retention. Only patients who have a good response to percutaneous nerve evaluation are candidates for implantation. The high efficacy in patients who undergo implantation, relative simplicity of the procedure and low complication rate make this a treatment breakthrough in this difficult group.

Over an 11-year period (1971 to 1981), 212 urinary conduit surgeries were performed by the Department of Gynecology at the University of Texas, M. D. Anderson Hospital and Tumor Institute at Houston. The urinary diversions were performed as part of the pelvic exenteration operation in 154 patients, for radiation injury in 48 patients, and for palliation of disease recurrence in ten patients. Ninety-three percent had prior pelvic radiotherapy. Various segments of the gastrointestinal tract were used, including the ileum (102), sigmoid colon (99), transverse colon (four), jejunum (four), and others (three). Fifty percent of abnormal preoperative intravenous pyelograms reverted tomore » normal after urinary diversion. Revision of the stoma was required in 6%. Other complications included infection (18%), renal loss (17%), and urinary leaks and fistulae (3%). The overall perioperative mortality was 7%, decreasing from 11% in the first five years to 3% during the last six years. Ureteral stents were routinely used. When selecting a segment of bowel for a urinary conduit, both tissue quality and mobility are important.

Health-Related Quality of Life after Cystectomy and Urinary Diversion for Bladder Cancer

PubMed Central

Shih, Cheryl; Porter, Michael P.

2011-01-01

With multiple options for urinary diversion after radical cystectomy for bladder cancer that have comparable cancer control and complication rates, health-related quality of life (HRQOL) has become an important consideration. This article reviews the methods for defining HRQOL, the challenges in measuring HRQOL in bladder cancer, and the literature comparing HRQOL after various methods of urinary diversion. Recent contributions include the validation of HRQOL instruments specific to bladder cancer and the publication of several prospective studies measuring HRQOL outcomes after cystectomy and urinary diversion. There is no convincing evidence from existing literature that any particular method of urinary diversion offers superior HRQOL outcomes. Rather, there is growing evidence that good HRQOL can be achieved with patient education and consideration of each patient's clinical and psychosocial situation. Future research should utilize the validated bladder cancer specific HRQOL instruments and perhaps explore the impact of preoperative counseling on postoperative HRQOL. PMID:21826139

Tran, Henry; Chung, Doreen E

2017-09-12

Pelvic organ prolapse (POP) is a significant problem with many options for surgical correction. Following prolapse surgery, de novo lower urinary tract symptoms (LUTS) are not uncommon. We review the current literature on de novo lower urinary tract symptoms following POP repair and discuss the role of urodynamics in the evaluation of the prolapse patient. Patients with occult stress urinary incontinence (SUI) appear to be at higher risk of developing de novo SUI after POP repair. Prolapse reduction in patients undergoing urodynamic evaluation is important. Different types of POP repair influence rates of de novo SUI. Also, prophylactic anti-incontinence procedures at time of POP repair appear to lower the incidence of de novo SUI, but at the cost of increased risk of complications and morbidity. Pre-existing overactive bladder (OAB) symptoms may either improve or persist, and de novo OAB can develop. The specific role of urodynamic study testing for POP is still being determined. Increasingly, women are seeking surgical treatment for POP. Aside from complications related to surgery in general, proper patient counseling is important regarding the risk of development of de novo voiding problems following surgery. Despite a growing body of literature looking at de novo voiding symptoms after prolapse repair, more studies are still needed.

Urinary tract infections (UTI) cause a great number of morbidity and mortality. These infections are serious complications in pregnancy, patients with diabetes, polycystic kidneys disease, sickle cell anaemia, kidney transplant and in patients with functional or structural anomalies of the urinary tract. The aim of this investigation was to determine a dominant causative agents of UTI and some of the clinical and laboratory characteristics of acute community-acquired UTI in adult hospitalised patients. We studied 200 adult patients with acute community-acquired UTI hospitalised in the Clinic for Infectious Diseases Tuzla from January 2006 to December 2007. The patients were divided into two groups: a group of patients with E. coli UTI (147) and a group of patients with non-E. coli UTI (53). In these two groups, the symptoms and signs of illness, blood test and urine analysis results were analysed. Our results have shown that the patients with E. coli UTI frequently had fever higher than 38,5 degrees C (p<0,0001), chills (p=0,0349), headache (p=0,0499), cloudy urine (p<0,0001), proteinuria (p=0,0011) and positive nitrite-test (p=0,0002). The patients with non-E. coli UTI frequently had fever lower than 38,5 degrees C (p<0,0001) and urine specific gravity <1015 (p=0,0012). There was no significant difference in blood test results between patients with E. coli and non-E. coli UTI. These clinical and laboratory findings can lead us to early etiological diagnosis of these UTI before urine culture detection of causative agents, which takes several days. Early etiological diagnosis of the E. coli and non-E. coli UTI is necessary for an urgent administration of appropriate empirical antibiotic treatment. This is very important in prevention of irreversible kidney damage, prolonged treatment, complications, as well as recidives and chronicity of the illness.

Urinary tract infection will develop in 40% of children who undergo renal transplantation. Post-transplant urinary tract infection is associated with earlier graft loss in adults. However, the impact on graft function in the pediatric population is less well-known. Additionally the risk factors for post-transplant urinary tract infection in children have not been well elucidated. The purpose of this study was to assess the relationship between pre-transplant and post-transplant urinary tract infections on graft outcome, and the risk factors for post-transplant urinary tract infection. A total of 87 patients underwent renal transplantation between July 2001 and July 2006. Patient demographics, cause of renal failure, graft outcome, and presence of pre-transplant and post-transplant urinary tract infections were recorded. Graft outcome was based on last creatinine and nephrological assessment. Median followup was 3.12 years. Of the patients 15% had pre-transplant and 32% had post-transplant urinary tract infections. Good graft function was seen in 60% of the patients and 21% had failed function. Graft function did not correlate with a history of pre-transplant or post-transplant urinary tract infection (p >0.2). Of transplanted patients with urological causes of renal failure 57% had post-transplant urinary tract infection, compared to only 20% of those with a medical etiology of renal failure (p <0.001). In this study there was no correlation between a history of urinary tract infection (either before or after transplant) and decreased graft function. History of pre-transplant urinary tract infection was suggestive of urinary tract infection after transplant. Patients with urological causes of renal failure may be at increased risk for post-transplant urinary tract infection. Copyright © 2010 American Urological Association Education and Research, Inc.

Eisenberg, Michael L; Elliott, Sean P; McAninch, Jack W

2007-12-01

We describe our experience with urethral stents to manage iatrogenic posterior urethral stenosis. We surveyed our retrospective database for patients in whom we placed a urethral stent for posterior urethral stricture disease. We reviewed patient age, comorbidities, indications for stent placement, stricture length, postoperative complications and the repeat stenosis rate. Overall we placed urethral stents in 13 patients, of whom 12 presented with posterior urethral stenosis and 1 presented with anterior and posterior stricture. The etiology of urethral stricture was prostate cancer therapy in 11 of 13 cases and simple prostatectomy in 2. Urethral stenting was chosen instead of urethral reconstruction largely due to prior radiation for prostate cancer and avoidance of the morbidity of surgery. Overall 6 of 13 patients required additional procedures for stricture recurrence, including 5 in previously irradiated patients. Two patients had stents removed due to migration or pain. Genitourinary infections developed in 5 of 13 patients. Eight of 13 patients with a posterior urethral stricture were incontinent, as expected after stent placement. Incontinence was managed by an artificial urinary sphincter in willing patients with 9 of 13 continent. Urethral stents provide reasonable treatment for patients with posterior urethral stenosis when attempting to preserve lower urinary tract function caused by stricture disease after prostate cancer therapy. Prior radiation seems to increase the failure rate. Continence can be maintained after posterior urethral stenting in select patients.

To report the outcomes of surgical management of urinary tract endometriosis. Retrospective study based on prospectively recorded data (NCT02294825) (Canadian Task Force classification II-3). University tertiary referral center. Eighty-one women treated for urinary tract endometriosis between July 2009 and December 2015 were included, including 39 with bladder endometriosis, 31 with ureteral endometriosis, and 11 with both ureteral and bladder endometriosis. Owing to bilateral ureteral localization in 8 women, 50 different ureteral procedures were recorded. Procedures performed included resection of bladder endometriosis nodules, advanced ureterolysis, ureteral resection followed by end-to-end anastomosis, and ureteroneocystostomy. The main outcome measure was the outcome of the surgical management of urinary tract endometriosis. Fifty women presented with deep infiltrating endometriosis (DIE) of the bladder and underwent either full-thickness excision of the nodule (70%) or excision of the bladder wall without opening of the bladder (30%). Ureteral lesions were treated by ureterolysis in 78% of the patients and by primary segmental resection in 22%. No patient required nephrectomy. Histological analysis revealed intrinsic ureteral endometriosis in 54.5% of cases. Clavien-Dindo grade III complications were present in 16% of the patients who underwent surgery for ureteral nodules and in 8% of those who underwent surgery for bladder endometriosis. Overall delayed postoperative outcomes were favorable regarding urinary symptoms and fertility. Patients were followed up for a minimum of 12 months and a maximum of 7 years postoperatively, with no recorded recurrences. Surgical outcomes of urinary tract endometriosis are generally satisfactory; however, the risk of postoperative complications should be taken into consideration. Therefore, all such procedures should be managed by an experienced multidisciplinary team. Copyright © 2017 AAGL. Published by Elsevier Inc. All rights reserved.

Urinary tract infections are common infectious diseases which can occur in any part of the urinary tract such as bladder, kidney, ureters, and urethra. They are commonly caused by bacteria that enter through the urethra. Urinary tract infections commonly develop in the bladder and spread to renal tissues. Up to now, there are different antimicrobial agents which have beneficial role on urinary tract infections. However, most of them cause different adverse effects and therefore, much attention has been paid to the search for effective therapeutic agents with negligible adverse effects. Cranberry is known as one of the most important edible plants, which possesses potent antimicrobial effects against the bacteria responsible for urinary tract infections. Growing evidence has shown that cranberry suppresses urinary tract infections and eradicates the bacteria. Therefore, the aim of this study is to critically review the available literature regarding the antimicrobial activities of cranberry against urinary tract infection microorganisms. In addition, we discuss etiology, epidemiology, risk factors, and current drugs of urinary tract infections to provide a more complete picture of this disease.

Use of drug therapy in the management of symptomatic ureteric stones in hospitalized adults (SUSPEND), a multicentre, placebo-controlled, randomized trial of a calcium-channel blocker (nifedipine) and an α-blocker (tamsulosin): study protocol for a randomized controlled trial

PubMed Central

2014-01-01

Background Urinary stone disease is common, with an estimated prevalence among the general population of 2% to 3%. Ureteric stones can cause severe pain and have a significant impact on quality of life, accounting for over 15,000 hospital admissions in England annually. Uncomplicated cases of smaller stones in the lower ureter are traditionally treated expectantly. Those who fail standard care or develop complications undergo active treatment, such as extracorporeal shock wave lithotripsy or ureteroscopy with stone retrieval. Such interventions are expensive, require urological expertise and carry a risk of complications. Growing understanding of ureteric function and pathophysiology has led to the hypothesis that drugs causing relaxation of ureteric smooth muscle, such as the selective α-blocker tamsulosin and the calcium-channel blocker nifedipine, can enhance the spontaneous passage of ureteric stones. The use of drugs in augmenting stone passage, reducing the morbidity and costs associated with ureteric stone disease, is promising. However, the majority of clinical trials conducted to date have been small, poor to moderate quality and lacking in comprehensive economic evaluation. This trial aims to determine the clinical and cost-effectiveness of tamsulosin and nifedipine in the management of symptomatic urinary stones. Methods/design The SUSPEND (Spontaneous Urinary Stone Passage ENabled by Drugs) trial is a multicentre, double-blind, randomized controlled trial evaluating two medical expulsive therapy strategies (nifedipine or tamsulosin) versus placebo. Patients aged 18 to 65 with a ureteric stone confirmed by non-contrast computed tomography of the kidney, ureter and bladder will be randomized to receive nifedipine, tamsulosin or placebo (400 participants per arm) for a maximum of 28 days. The primary clinical outcome is spontaneous passage of ureteric stones at 4 weeks (defined as no further intervention required to facilitate stone passage). The primary economic outcome is a reduction in the incremental cost per quality-adjusted life years, determined at 12 weeks. The analysis will be based on all participants as randomized (intention to treat). The trial has 90% power with a type I error rate of 5% to detect a 10% increase in primary outcome between the tamsulosin and nifedipine treatment groups.

To compare the effectiveness and complications of TVT-Abbrevo (tension-free vaginal tape-Abbrevo) and TVT-Obturator (tension-free vaginal tape-obturator) for the treatment of female stress urinary incontinence (SUI). From Nov.2012 to Nov.2013, 117 patients suffering from SUI were treated with TVT-Abbrebo (n=79) or TVT-Obturator (n=38) procedure, the clinical efficacy and operation-correlated complications were observed. A total of 117 cases, 107 cases of urinary incontinence symptoms disappeared completely, 10 cases were improved. 72 cases (91.1%) were cured and 7 cases (8.9%) were improved in TVT-Abbrevo group; 35 cases (92.1%) were cured and 3 cases (7.9%) were improved in TVT-Obturator group. No significant differences could be found for the curing rates between two groups (P>0.05). Compared with the TVT-Obturator group, the TVT-Abbrevo group had less patients complaining of inner thigh pain at 24 h and 1 w after surgery (P<0.05). No significant differences were observed for the incidence of inner thigh pain at 1m and 1y after surgery between TVT-Abbrevo and TVT-Obturator group (P>0.05). No intraoperative complications such as blood vessel, nerve, bladder damage were recorded and no postoperative retropubic hematoma, tape adjustment and other complications occurred in two goups. No recurrence after 1 year follow-up. The study shows that TVT-Abbrevo procedure is safe and efficacy in treatment of SUI, and associated with low incidence of recent postoperative inner thigh pain.

Management of complicated open wounds represents a challenge when reconstructive options are not applicable. Urinary bladder matrix (UBM) provides a biocompatible material that allows inductivetissue remodeling. The use of urinary bladder matrix inthe treatment of 5 patients with complicated open wounds that failed toheal with conventional therapy is presented. A 3-year old male sustained a second-degree oil burn measuring 8 cm x 4 cm to his dorsal forearm; UBM was applied weekly and the wound epithelialized in 3 weeks. A 52-year old male sustained massive second and third degree burns to his leg after a fire; UBM was applied weekly and the wound epithelialized in 28 weeks. A 61-year old female sustained a severe crushing injury to her right knee. A gastrocnemius muscle transfer and rectus abdominus muscle free flap transfer both failed, then UBM and vacuum-assisted closure therapy were applied and the wound epithelialized in 24 weeks. A 54-year old female underwent a breast mastectomy and immediate reconstruction with pedicled transverse rectus abdominus flap. The patient developed partial necrosis and the wound was managed with UBM and vacuum-assisted closure therapy. The wound epithelialized in 12 weeks. A 36-year old female sustained severe degloving injuries to both hands with exposed metacarpals. Weekly application of UBM provided tissue remodeling over the bones, which allowed successful skin grafting and closure. These experiences show UBM to be an effective method in management of complicated open wounds in select cases. Further studies need to be implemented to confirm this conclusion.

Background/Aims/Objectives: To analyze perioperative complication and short-term explantation rates after perineal or penoscrotal single-cuff and double-cuff artificial urinary sphincter (AUS) implantation in a large middle European multi-institutional patient cohort. 467 male patients with stress urinary incontinence underwent implantation of a perineal single-cuff (n = 152), penoscrotal single-cuff (n = 99), or perineal double-cuff (n = 216) AUS between 2010 and 2012. Postoperative complications and 6-month explantation rates were assessed. For statistical analysis, Fisher's exact test and Kruskal-Wallis rank sum test, and a multiple logistic regression model were used (p < 0.05). Compared to perineal single-cuff AUS, penoscrotal single-cuff implantation led to significantly increased short-term explantation rates (8.6% (perineal) vs. 19.2% (penoscrotal), p = 0.019). The postoperative infection rate was significantly higher after double-cuff compared to single-cuff implantation (6.0% (single-cuff) vs. 13.9% (double-cuff), p = 0.019). The short-term explantation rate after primary double-cuff placement was 6.5% (p = 0.543 vs. perineal single-cuff). In multivariate analysis, the penoscrotal approach (p = 0.004), intraoperative complications (p = 0.005), postoperative bleeding (p = 0.011), and perioperative infection (p < 0.001) were independent risk factors for short-term explantation. Providing data from a large contemporary multi-institutional patient cohort from high-volume and low-volume institutions, our results reflect the current standard of care in middle Europe. We indicate that the penoscrotal approach is an independent risk factor for increased short-term explantation rates. © 2016 S. Karger AG, Basel.

To assess the feasibility and outcomes of laparoscopic pyeloplasty in children with complex ureteropelvic junction obstruction (UPJO) and compare to children with iso-lated UPJO without associated urinary tract abnormalities. Medical records of 82 consecutive children submitted to transperitoneal laparoscopic pyeloplasty in a 12-year period were reviewed. Eleven cases were con-sidered complex, consisting of atypical anatomy including horseshoe kidneys in 6 patients, pelvic kidneys in 3 patients, and a duplex collecting system in 2 patients. Patients were di-vided into 2 groups: normal anatomy (group 1) and complex cases (group 2). Demographics, perioperative data, outcomes and complications were recorded and analyzed. Mean age was 8.9 years (0.5-17.9) for group 1 and 5.9 years (0.5-17.2) for group 2, p=0.08. The median operative time was 200 minutes (180-230) for group 1 and 203 minutes (120-300) for group 2, p=0.15. Major complications (Clavien ≥3) were 4 (5.6%) in group 1 and 1 (6.3%) in group 2, p=0.52. No deaths or early postoperative complications such as: urinoma or urinary leakage or bleeding, occurred. The success rate for radiologic improvement and flank pain improvement was comparable between the two groups. Re-garding hydronephrosis, significant improvement was present in 62 patients (93.4%) of group 1 and 10 cases (90.9%) of group 2, p=0.99. The median hospital stay was 4 days (IQR 3-4) for group 1 and 4.8 days (IQR 3-6) for group 2, p=0.27. Transperitoneal laparoscopic pyeloplasty is feasible and effective for the management of UPJO associated with renal or urinary tract anomalies.

Prevention of recurrent urinary tract infections.

Urinary tract infections (UTI) are among the most frequent bacterial infections in the community and health care setting. Mostly young and, to some extent, postmenopausal women are affected by recurrent UTI (rUTI) defined as ≥3 UTI/year or ≥2 UTI/half year. In contrast, rUTI is rare in healthy men. On the other hand, rUTI are frequently found in female and male patients with complicating urological factors, e.g. urinary catheters, infection stones. Remediable predisposing factors in uncomplicated rUTI in women are rare. In complicated rUTI the success depends mainly on the possibility to eliminate or at leastimprove the complicating risk factors. Continuous antibiotic prophylaxis or postcoital prophylaxis, if there is close correlation with sexual intercourse, are most effective to prevent rUTI. Nitrofurantoin, trimethoprim (or cotrimoxazole), and fosfomycin trometamol are available as first-line drugs. Oral cephalosporins and quinolones should be restricted to specific indications. Antibiotic prophylaxis reduces the number of uropathogens in the gut and/or vaginal flora and reduces bacterial "fitness". Given the correct indication, the recurrence rate of rUTI can be reduced by about 90%. Due to possible adverse events and the concern of selecting resistant pathogens, according to the guidelines of the European Association of Urology antimicrobial prophylaxis should be considered only after counselling, behavioural modification and non-antimicrobial measures have been attempted. In postmenopausal patients vaginal substitution of oestriol should be started first. Oral or parenteral immunoprophylaxis is another option in patients with rUTI. Other possibilities with varying scientific evidence are prophylaxis with cranberry products, specific plant combinations or probiotics. The prophylaxis of catheter-associated UTI should employ strategies which result in a reduction of frequency and duration of catheter drainage of the urinary tract. The currently available catheter materials have only little influence on reducing catheter-associated rUTI.

The article presents a simplified NMR-based protocol for urinary profiling of lactulose/mannitol ratio (LMR) and demonstrates here its utility to assess increased intestinal permeability (IP) in patients with acute on chronic liver failure (ACLF). ACLF is a serious clinical complication associated with chronic liver disease (cirrhosis). The major risk factor in its development is increased IP ('leaky gut'), which has been linked to disease progression and to infectious complications. However, IP has seldom been investigated in patients with ACLF, even though patients frequently report gastrointestinal disorders and associated complications. To this end, we first optimized the NMR-based targeted profiling of urinary metabolites (i.e. actulose, mannitol, and creatinine) and subsequently used this resulted protocol (a) first to evaluate the altered IP in ACLF patients and then (b) to explore its utility for monitoring the treatment response in these patients. The normal profiles were obtained for 7 age and sex matched healthy volunteers. The results revealed that the urinary LMR excretion was significantly higher in ACLF patients compared to normal controls (median ~0.7, range (0.12-2.84), vs median ~0.11, range (0.02-0.28), p < 0.001) suggesting that the ACLF patients' exhibit altered IP. However, the LMR excretion in six clinically improved follow-up ACLF patients was comparable to normal controls indicating restored IP after the treatment. The protocol-as demonstrated here with ACLF-is equally applicable for evaluating IP or mucosal barrier function in other intestinal disorders with reasonable sensitivity and specificity, highlighting its general utility.

Those patients who failed to achieve continence after a procedure aimed to correct it, require a special attitude and precise management due to the sophisticated anatomical and functional field of interest. The purpose of the present study was to assess long-term clinical efficacy and evaluate the frequency and severity of any complications related to recurrent stress urinary incontinence treatment with a non-absorbable bulking agent periurethral injections. Between February 2012-September 2013, 66 patients with recurrent stress urinary incontinence were treated with Urolastic in the tertiary referral gynecologic department. The efficacy of the procedure was assessed objectively at each follow-up visit, scheduled at two, six weeks and 3, 6, 12 and 24 months after primary procedure. Material was injected under local anesthesia according to the manufacturer's instructions, at 10, 2, 4 and 8 o'clock positions with 0.5-1.25ccm per spot. Statistical analyses were performed with Statistica package version 8.0 (StatSoft Inc., Tulsa, OK, USA). A p value <0.05 was considered statistically significant. Objective success rate at 24 months was found in 32.7% of patients, including 22.4% patients who were completely dry. The efficacy of Urolastic, when considering the intention to treat, is 24.2% and 16.7%, respectively. In 4.5% patients an oval shaped material was found inside the bladder. Overall, complications were observed in 17 (25.8%) patients. Although only 30% of patients will benefit from Urolastic injection on the long-term basis it seems to be a safe procedure in the treatment of recurrent stress urinary incontinence.

Urinary tract infections in patients with spinal cord injuries.

PubMed

D'Hondt, Frederiek; Everaert, Karel

2011-12-01

Spinal cord injuries (SCI) result in different lower urinary tract dysfunctions. Because of both the disease and the bladder drainage method, urinary tract infections (UTIs) are one of the most frequent conditions seen in SCI patients. Diagnosis is not always easy due to lack of symptoms. Asymptomatic bacteriuria needs no treatment. If symptoms occur, antibiotherapy is indicated. Duration depends mainly on severity of illness and upper urinary tract or prostatic involvement. Choice of antibiotherapy should be based on local resistance profiles, but fluoroquinolones seems to be an adequate empirical treatment. Prevention of UTI is important, as lots of complications can be foreseen. Catheter care, permanent low bladder pressure and clean intermittent catheterization (CIC) with hydrophilic catheters are interventions that can prevent UTI. Probiotics might be useful, but data are limited.

Effect of Age, Educational Status, Parity and BMI on Development of Urinary Incontinence - a Cross Sectional Study in Saudi Population.

The research article looks at the background of women with urinary incontinence and exposed to different demographic factors. Women who had urinary incontinence and women without urinary incontinence were compared with regards to their demographic features and risk of development of urinary problems. These risk factors can either cause short term or temporary urinary incontinence or they can cause long term or permanent urinary incontinence. This article explores the association of age, educational status, body mass index (BMI) and parity on the development of urinary incontinence. This study aimed at conducting an analysis into the risk factors that are related to urinary incontinence. Z-tests were conducted for every demographic factor and the results are then discussed comprehensively citing various studies that have been conducted before. Analysis shows that age and BMI increase chances of urinary infection and consequently urinary incontinence. Women of lower educational levels record more cases of urinary incontinence due to lack of general information about the condition. Women with higher parity levels also record more cases of urinary infections and subsequently urinary incontinence. From the analysis above, it can be seen that these factors usually play great roles in the existence and absence of urinary incontinence especially in women in Saudi Arabia. Most important is that, its prevention is mostly by use of the risk factors mentioned here in the research. This will usually involve observing a given risk factor to a state that makes it unfavorable for urinary incontinence to occur.

Urethral stricture is a common condition that can lead to serious complications such as urinary infections and renal insufficiency secondary to urinary retention. Treatment options include catheterization, urethroplasty, endoscopic internal urethrotomy, and dilation. Optical internal urethrotomy offers faster recovery, minimal scarring, and less risk of infection, although recurrence is possible. However, technical difficulties associated with poor visualization of the stenosis or of the urethral lumen may increase procedural time and substantially increase the failure rates of internal urethrotomy. In this report we describe a technique for urethral catheterization via a suprapubic, percutaneous approach through the urinary bladder in order to facilitate endoscopic internal urethrotomy.

Ureteral stents are routinely used in renal transplant and are associated with reduced urological complications but increased urinary tract infections (UTIs). There is no agreement on the preferred time to removal of stents after transplantation. We performed a systematic review and meta-analysis of all randomized controlled trials (RCTs) comparing stent duration of <14 days vs > =14 days. Electronic databases were searched to identify RCTs that compared early vs late stent removal. Primary outcome was urinary tract infections. Secondary outcomes included various urological complications. No significant difference in UTI rates was demonstrated between short and long stent duration (relative risk (RR) 0.85, 95% confidence interval (CI) 0.44-1.64), with significant heterogeneity (I 2  = 86%). Sensitivity analysis evaluating studies with low risk of bias for allocation concealment demonstrated statistically significant lower rates of UTI with short stent duration (RR 0.48, 95% CI 0.32-0.71) with no heterogeneity. No significant difference was demonstrated for the outcome of major urological complications (RR 0.72, 95% CI 0.50-1.05), without heterogeneity. Ureteral stenosis rates were significantly lower in the short duration arm (RR 0.42, 95% CI 0.18-0.98). Early removal of ureteral stents after renal transplant may be associated with reduced rates of UTI and ureteral stenosis. Additional RCTs are needed.

The AdVance sling (American Medical Systems, Minnetonka, MN, United States of America) is a synthetic transobturator sling, which is a safe and effective minimally invasive treatment for mild to moderate stress urinary incontinence (SUI) in male patients. This article provides a step-by-step description of our technique for placement of the AdVance male sling, including details and nuances gained from surgical experience, advice for avoidance of complications and discussion on management of complications and sling failures. Patient selection is very important, including exclusion and preoperative treatment of urethral stenosis and bladder dysfunction. Previous pelvic radiation is a poor prognostic factor. In brief, the steps of sling placement are: (I) mobilization of the corpus spongiosum (CS); (II) marking and mobilization of the central tendon; (III) passage of the helical trocar needles exiting at the apex of the angle between the CS and inferior pubic ramus; (IV) fixation of the broad part of the sling body to the CS at the previous mark; (V) cystoscopy during sling tensioning; (VI) placement of a Foley urethral catheter; (VII) Subcutaneous tunnelling of the sling arms back toward the midline; (VIII) wound closure. The most common early postoperative complication is urinary retention but long-term retention is extremely rare. Management of sling failures include placement of an artificial urinary sphincter, repeat AdVance sling, urethral bulking agent or ProACT device. PMID:28904900

We would like to propose re-establishment of the protocol for ordering a clinical microbiology laboratory test after a bedside screening test using urine reagent strip when urinary tract infection is suspected. Media for isolation shall be chosen by the clinical microbiology laboratory after checking turbidity and microscopic examination of the urine specimen. In cases of complicated urinary tract infections, quantitative culture should be performed to investigate changes in the number of microorganism to grasp condition of super infection. In such infections, there are many cases in which multiple microorganism growth including glucose non-fermenting gram-negative bacilli can be recognized. Therefore, it is necessary to inspect colonies on media as long as possible (24 hrs culture may be short in some cases). The protocol for microorganism identification and susceptibility test for such specimen varies in each laboratory, considering the Health Insurance Point System (reimbursement system by MHW). It is necessary to communicate with physicians and to refer to past results to proceed with the laboratory test properly. Therefore, a Certified Clinical Microbiology Medical Technologist is needed and the role played by such staff is important.

Although most cases of immunoglobulin A (IgA) nephropathy are idiopathic, several diseases are associated with IgA nephropathy. Of these, chronic liver disease resulting from hepatitis B or C virus infection has been reported as a secondary cause of IgA nephropathy. Recently, hepatitis A virus (HAV)-associated kidney disease has received attention because acute kidney injury can occur as a complication of HAV infection, generally caused by acute tubular necrosis or interstitial nephritis. However, unlike IgA nephropathy related to hepatitis B or C, HAV-associated IgA nephropathy is extremely rare and long-term outcomes have not been reported yet. We describe a case of spontaneous remission of IgA nephropathy associated with serologically documented HAV infection. The patient presented with microhematuria and moderate proteinuria, but acute kidney injury did not occur during active hepatic injury. Kidney biopsy specimens clearly showed mesangial IgA deposits with intact tubules and interstitium. Serum liver enzyme levels returned to reference values 1 month after the onset of acute hepatitis, but urinary protein excretion remained increased. Approximately 1 year later, urinary abnormalities were resolved and a second biopsy showed no mesangial IgA deposits. These findings suggest that IgA nephropathy can transiently accompany HAV infection, but may not progress to chronic glomerulonephritis after recovery from HAV.

Traumatic neuroma is a reactive process caused by the regeneration of an injured nerve that usually forms a nodular proliferation of small nerve bundles. Penile traumatic neuroma is rare; only a few cases related to circumcision have been reported. To report on a case of traumatic neuroma in the penis after selective dorsal neurotomy (SDN) to treat premature ejaculation. The penile traumatic neuroma was successfully removed by excision and confirmed by histopathology. A 55-year-old man who had had several painless, slow-growing nodules on his penis for 2 years presented to our hospital. He had no history of genital trauma, urinary tract infection, or penile surgery, except SDN to treat premature ejaculation. The nodules were excised and the final diagnosis was traumatic neuroma. No recurrence has been detected during 1 year of follow-up. The main complications of SDN are recurrence of premature ejaculation, pain or paresthesia on the glans penis, and erectile dysfunction. However, no traumatic neuroma has been reported as a complication. We report that a traumatic neuroma can occur after SDN. Copyright © 2016 The Authors. Published by Elsevier Inc.

To gain insight into nurses' knowledge and attitudes regarding major immobility complications (pressure ulcers, pneumonia, deep vein thrombosis and urinary tract infections) and explore the correlation of nurses' knowledge and attitudes with the incidence of these complications. Immobility complications have adverse consequences, and effective management requires appropriate knowledge, attitudes and skills. Evidence about nurses' knowledge and attitudes regarding immobility complications is lacking. Cross-sectional study. A total of 3,903 nurses and 21,333 bedridden patients from 25 hospitals in China were surveyed. Nurses' knowledge and attitudes regarding major immobility complications were assessed using researcher-developed questionnaires. The content validity, reliability and internal consistency of the questionnaires were validated through expert review and a pilot study. The incidence of major immobility complications among bedridden patients from selected wards was surveyed by trained investigators. Correlations between knowledge, attitudes and the incidence of major immobility complications were evaluated with multilevel regression models. Mean knowledge scores were 64.07% for pressure ulcers, 72.92% for deep vein thrombosis, 76.54% for pneumonia and 83.30% for urinary tract infections. Mean attitude scores for these complications were 86.25%, 84.31%, 85.00% and 84.53%, respectively. Knowledge and attitude scores were significantly higher among nurses with older age, longer employment duration, higher education level, previous training experience and those working in tertiary hospitals or critical care units. Nurses' knowledge about pressure ulcers was negatively related to the incidence of pressure ulcers, and attitude towards pneumonia was negatively correlated with the incidence of pneumonia. Clinical nurses have relatively positive attitudes but inadequate knowledge regarding major immobility complications. Improved knowledge and attitudes regarding major immobility complications may contribute to reducing these complications. Nursing managers should implement measures to improve nurses' knowledge and attitudes regarding major immobility complications to reduce the incidence of these complications in bedridden patients. © 2018 John Wiley & Sons Ltd.

This systematic review was performed to assess the necessity and complications of stenting before extracorporeal shock wave lithotripsy in the management of upper urinary stones. A systematic research of PubMed®, EMBASE® and the Cochrane Library was performed to identify all randomized controlled trials. The comparisons were about the outcomes and complications of extracorporeal shock wave lithotripsy in the management of upper urinary stones with or without Double-J stenting before extracorporeal shock wave lithotripsy, including stone-free rate, Steinstrasse, lower urinary tract symptoms, hematuria, fever, urinary tract infection, pain and analgesia, auxiliary treatment, and nausea and vomiting. We used the Cochrane Collaboration's Review Manager (RevMan) 5.0.2 software for statistical analysis. Eight randomized controlled trials were included in analysis that reported 876 patients in total, divided into the stented group of 453 and the stentless group of 423. All studies recorded the stone-free rate and the results of the meta-analysis showed no difference between the groups (RR 0.97, 95% CI 0.91-1.03, p = 0.27). The total incidence of Steinstrasse in the stented group was similar to that of the stentless group with the exception of 1 study. However, the incidence of lower urinary tract symptoms was significantly higher in the stented group than in the stentless group (RR 4.10, 95% CI 2.21-7.61, p <0.00001). Significant differences could not be found in hematuria, fever, urinary tract infection, pain and analgesia, auxiliary treatment, or nausea and vomiting between the groups. The systematic review suggested significant advantages of stenting before extracorporeal shock wave lithotripsy compared to in situ extracorporeal shock wave lithotripsy in terms of Steinstrasse. However, stenting did not benefit stone-free rate and auxiliary treatment after extracorporeal shock wave lithotripsy, and it induced more lower urinary tract symptoms. More high quality, randomized controlled trials are needed to address this issue. Copyright © 2011 American Urological Association Education and Research, Inc. Published by Elsevier Inc.

Background and objectives We investigated the association of urinary potassium and sodium excretion with the incidence of renal failure and cardiovascular disease in patients with type 2 diabetes. Design, setting, participants, & measurements A total of 623 Japanese type 2 diabetic patients with eGFR≥60 ml/min per 1.73 m2 were enrolled in this observational follow-up study between 1996 and 2003 and followed-up until 2013. At baseline, a 24-hour urine sample was collected to estimate urinary potassium and sodium excretion. The primary end point was renal and cardiovascular events (RRT, myocardial infarction, angina pectoris, stroke, and peripheral vascular disease). The secondary renal end points were the incidence of a 50% decline in eGFR, progression to CKD stage 4 (eGFR<30 ml/min per 1.73 m2), and the annual decline rate in eGFR. Results During the 11-year median follow-up period, 134 primary end points occurred. Higher urinary potassium excretion was associated with lower risk of the primary end point, whereas urinary sodium excretion was not. The adjusted hazard ratios for the primary end point in Cox proportional hazards analysis were 0.56 (95% confidence interval [95% CI], 0.33 to 0.95) in the third quartile of urinary potassium excretion (2.33–2.90 g/d) and 0.33 (95% CI, 0.18 to 0.62) in the fourth quartile (>2.90 g/d) compared with the lowest quartile (<1.72 g/d). Similar associations were observed for the secondary renal end points. The annual decline rate in eGFR in the fourth quartile of urinary potassium excretion (–1.3 ml/min per 1.73 m2/y; 95% CI, –1.5 to –1.0) was significantly slower than those in the first quartile (–2.2; 95% CI, –2.4 to –1.8). Conclusions Higher urinary potassium excretion was associated with the slower decline of renal function and the lower incidence of cardiovascular complications in type 2 diabetic patients with normal renal function. Interventional trials are necessary to determine whether increasing dietary potassium is beneficial. PMID:26563378

Leiomyomas of urinary bladder constitute only about 0.43% of all bladder tumors. Only about 250 cases were reported in English literature. This is the first reported case of bladder leiomyoma to present with febrile urinary tract infection. We report a case of a 37- year old male who presented with febrile urinary tract infection. Imaging showed a bladder lesion. This lesion was managed by transurethral resection. Pathologic diagnosis was bladder leiomyoma. Although bladder leiomyomas are benign, they can cause serious sequelae, including serious urinary tract infections as the case we present here shows. This is why it is important to early diagnose and treat this condition. This case highlights the importance of early introduction of imaging in patients presenting with severe urinary tract infections. Failure to diagnose this lesion as the underlying cause of infection may have easily led to recurrence of similar severe life-threatening infections. Copyright © 2016 The Author(s).

Urinary retention in women often presents a diagnostic difficulty, and the etiology may remain unidentified even after excluding structural and neurological causes. We evaluated a group of women referred to a specialist center with unexplained urinary retention. A total of 61 consecutive women with complete urinary retention were evaluated. Urological and neurological investigations locally had failed to identify a cause. Urethral pressure profile, sphincter volume measurement and in some cases urethral sphincter electromyography were performed to diagnose a primary disorder of sphincter relaxation (Fowler's syndrome). Mean patient age was 39 years (range 18 to 88). Following investigations, a probable etiology was identified in 25 (41%) women, the most common being Fowler's syndrome. Of the women 24 (39%) were being treated with opiates for various pain syndromes and in 13 no other cause of retention was identified. Opiates could be discontinued in only 2 patients, and both demonstrated improved sensations and voiding. The cause of urinary retention may remain unknown in spite of extensive investigations. Young women regularly using prescription opiates for various undiagnosed pain syndromes present a challenging clinical problem and this study suggests that iatrogenic causes should be considered if voiding difficulties emerge. An association between opiate use and constipation is well-known and, although urinary retention is a listed adverse event, it appears to be often overlooked in clinical practice. It is hypothesized that Fowler's syndrome is due to an up-regulation of spinal cord enkephalins and that exogenous opiates may compound any functional abnormalities predisposing young women to urinary retention.

Wästfelt, Maja; Cao, Yang; Ström, Jakob O

2018-04-23

Fever after stroke is common, and often caused by infections. In the current study, we aimed to test the hypothesis that pneumonia, urinary tract infection and all-cause fever (thought to include at least some proportion of endogenous fever) have different predicting factors, since they differ regarding etiology. PubMed was searched systematically for articles describing predictors for post-stroke pneumonia, urinary tract infection and all-cause fever. A total of 5294 articles were manually assessed; first by title, then by abstract and finally by full text. Data was extracted from each study, and for variables reported in 3 or more articles, a meta-analysis was performed using a random effects model. Fifty-nine articles met the inclusion criteria. It was found that post-stroke pneumonia is predicted by age OR 1.07 (1.04-1.11), male sex OR 1.42 (1.17-1.74), National Institutes of Health Stroke Scale (NIHSS) OR 1.07 (1.05-1.09), dysphagia OR 3.53 (2.69-4.64), nasogastric tube OR 5.29 (3.01-9.32), diabetes OR 1.15 (1.08-1.23), mechanical ventilation OR 4.65 (2.50-8.65), smoking OR 1.16 (1.08-1.26), Chronic Obstructive Pulmonary Disease (COPD) OR 4.48 (1.82-11.00) and atrial fibrillation OR 1.37 (1.22-1.55). An opposite relation to sex may exist for UTI, which seems to be more common in women. The lack of studies simultaneously studying a wide range of predictors for UTI or all-cause fever calls for future research in this area. The importance of new research would be to improve our understanding of fever complications to facilitate greater vigilance, monitoring, prevention, diagnosis and treatment.

Although catatonia can occur secondary to a general medical condition, catatonia itself has been known to lead to various medical compolications. Although case reports on the association of catatonia with subsequent medical complications have been documented, no comprehensive large-scale study has been performed. To investigate specific medical complications after catatonia, we conducted a retrospective cohort study of specific medical complications of schizophrenia patients with catatonia. The 1719 schizophrenia inpatients in our study were categorized into two groups: the catatonia group, i.e., those who exhibited catatonic stupor while they were hospitalized, and the noncatatonia group, i.e., those who never exhibited catatonic stupor. Differences between the two groups in the occurrence of subsequent medical complications were examined using linear and logistic regression analyses, and models were adjusted for potentially confounding factors. The catatonia group had an increased risk for mortality (odds ratio = 4.8, 95% confidence interval = 2.0-10.6, p < .01) and certain specific medical complications, i.e., pneumonia, urinary tract infection, sepsis, disseminated intravascular coagulation, rhabdomyolysis, dehydration, deep venous thrombosis, pulmonary embolism, urinary retention, decubitus, arrhythmia, renal failure, neuroleptic malignant syndrome, hypernatremia, and liver dysfunction (all p values < .01, except for deep venous thrombosis, p = .04 in the multiple linear regression analysis). Catatonic stupor in schizophrenia substantially raises the risk for specific medical complications and mortality. Hyperactivity of the sympathetic nervous system, dehydration, and immobility, which are frequently involved in catatonia, might contribute to these specific medical complications. In catatonia, meticulous care for both mental and medical conditions should be taken to reduce the risk of adverse medical consequences.

2015-01-01

Objective Normal pressure hydrocephalus (NPH) is a syndrome characterized by gait disturbance, memory impairment and urinary incontinence. The isotope cisternography (ICG) became less useful because of low accuracy and complications. We tried to evaluate the safety and value of the ICG. Methods We retrospectively collected data on ICG of 175 consecutive patients with a suspected hydrocephalus. We classified the ICG into four types by the ventricular reflux and circulation time. The ventricular size was measured by Evans index and the width of the third ventricle. Results There were three complications including one case of paraplegia. Type 4 was the most common type, observed in 53%. Type 3 (33%), type 2 (7%), and type 1 (7%) were observed less often. Type 4 was more common in patients with large ventricles. Types of the ICG were not related to the causes of hydrocephalus, gender, or age of the patients. Shunting was more frequently performed in type 4 (71%), compared to type 1 (17%), type 2 (33%), and type 3 (46%). Surgery was more common when the cause was vascular. After the shunt surgery, 33.0% were graded as the improved. Although there were some improvements even in the not-improved patients, they still needed many helps. The improvement was related to the preoperative state. Conclusion ICG may bring a serious complication, however the incidence is very low. Although the predictability of response rate on the shunting is doubtful, ICG is a cheap and useful tool to select surgical candidates in NPH. PMID:27169059

Long-term complications following bladder augmentations in patients with spina bifida: bladder calculi, perforation of the augmented bladder and upper tract deterioration.

PubMed

Husmann, Douglas A

2016-02-01

We desire to review our experience with bladder augmentation in spina bifida patients followed in a transitional and adult urologic practice. This paper will specifically focus on three major complications: bladder calculi, the most frequent complication found following bladder augmentation, perforation of the augmentation, its most lethal complication and finally we will address loss of renal function as a direct result of our surgical reconstructive procedures. We reviewed a prospective data base maintained on patients with spina bifida followed in our transitional and adult urology clinic from 1986 to date. Specific attention was given to patients who had developed bladder calculi, sustained a spontaneous perforation of the augmented bladder or had developed new onset of renal scarring or renal insufficiency (≥ stage 3 renal failure) during prolonged follow-up. The development of renal stones (P<0.05) and symptomatic urinary tract infections (P<0.0001) were found to be significantly reduced by the use of high volume (≥240 mL) daily bladder wash outs. Individuals who still developed bladder calculi recalcitrant to high volume wash outs were not benefited by the correction of underlying metabolic abnormalities or mucolytic agents. Spontaneous bladder perforations in the adult patient population with spina bifida were found to be directly correlated to substance abuse and noncompliance with intermittent catheterization, P<0.005. Deterioration of the upper tracts as defined by the new onset of renal scars occurred in 40% (32/80) of the patients managed by a ileocystoplasty and simultaneous bladder neck outlet procedure during a median follow-up interval 14 years (range, 8-45 years). Development of ≥ stage 3 chronic renal failure occurred within 38% (12/32) of the patients with scarring i.e., 15% (12/80) of the total patient population. Prior to the development of the renal scarring, 69% (22/32) of the patients had been noncompliant with intermittent catheterization. The onset of upper tract deterioration (i.e., new scar formation, hydronephrosis, calculus development, decrease in renal function) was silent, that is, clinically asymptomatic in one third (10/32 pts). This paper documents the need for high volume bladder irrigations to both prevent the most common complication following bladder augmentation, which is the development of bladder calculi and to reduce the incidence of symptomatic urinary tract infections. It provides a unique perspective regarding the impact of substance abuse and patient non-compliance with medical directives as being both the most common cause for both spontaneous bladder rupture following augmentation cystoplasty and for deterioration of the upper tracts. These findings should cause the surgeon to reflect on his/her assessment of a patient prior to performing a bladder augmentation procedure and stress the need for close follow-up.

Lower urinary tract dysfunction in critical illness polyneuropathy.

Reitz, André

2013-01-01

Critical illness polyneuropathy is a frequent complication of critical illness in intensive care units. Reports on autonomic systems like lower urinary tract and bowel functions in patients with CIP are not available in medical literature. This study performed during primary rehabilitation of patients with critical illness polyneuropathy explores if sensory and motor pathways controlling the lower urinary tract function are affected from the disease. Neurourological examinations, urodynamics, electromyography and lower urinary tract imaging were performed in 28 patients with critical illness polyneuropathy. Sacral sensation was impaired in 1 patient (4%). Sacral reflexes were absent in 8 patients (30%). Anal sphincter resting tone was reduced in 3 (12%), anal sphincter voluntary contraction was absent or reduced in 8 patients (30%). Urodynamic findings were detrusor overactivity and detrusor overactivity incontinence in 9 (37.5%), incomplete voiding in 8 (30%), abnormal sphincter activity in 4 (16%), abnormal bladder sensation in 4 (16%) and detrusor acontractility in 2 patients (8.3%). Morphological abnormalities of the lower urinary tract had 10 patients (41.6%). Sensory and motor pathways controlling the lower urinary tract might be affected from CIP. During urodynamics dysfunctions of the storage as well as the voiding phase were found. Morphological lower urinary tract abnormalities were common.

antenatal variant of Bartter syndrome is characterized by a history of polyhydramnios, premature birth, metabolic alkalosis, hypokalemia, polyuria and renal salt wasting. In this report we present a premature female baby with antenatal Barter syndrome who had three episodes of urinary tract infection (UTI), without evidence for congenital anomaly of the kidneys or urinary tract. antenatal Bartter syndrome was diagnosed according to the standard criteria. Ultrasound scan and voiding cystourethrography were performed to exclude congenital anomaly of the kidneys and urinary tract. the baby presented with early hyperkalemia and acidosis. The typical biochemical features of the Bartter syndrome were observed in the second month. Despite appropriate treatment she had persistent hypercalciuria. The clinical course was complicated with recurrent episodes of febrile UTIs. Urinary tract system imaging did not demonstrate congenital anomalies. She finally died of severe dehydration, acidosis and renal failure. since no congenital anomaly of the kidneys or urinary tract was demonstrated in our patient, we believe that severe, persistent hypercalciuria is the most important risk factor for development of recurrent UTIs.

Catheter associated urinary tract infections

PubMed Central

2014-01-01

Urinary tract infection attributed to the use of an indwelling urinary catheter is one of the most common infections acquired by patients in health care facilities. As biofilm ultimately develops on all of these devices, the major determinant for development of bacteriuria is duration of catheterization. While the proportion of bacteriuric subjects who develop symptomatic infection is low, the high frequency of use of indwelling urinary catheters means there is a substantial burden attributable to these infections. Catheter-acquired urinary infection is the source for about 20% of episodes of health-care acquired bacteremia in acute care facilities, and over 50% in long term care facilities. The most important interventions to prevent bacteriuria and infection are to limit indwelling catheter use and, when catheter use is necessary, to discontinue the catheter as soon as clinically feasible. Infection control programs in health care facilities must implement and monitor strategies to limit catheter-acquired urinary infection, including surveillance of catheter use, appropriateness of catheter indications, and complications. Ultimately, prevention of these infections will require technical advances in catheter materials which prevent biofilm formation. PMID:25075308

Nursing Sensitive Outcomes After Severe Traumatic Brain Injury: A Nationwide Study.

2018-06-01

Complications such as infections and conditions after immobilization are frequent after severe traumatic brain injury (TBI) due to compromised bodily functions. Traditionally, bodily functions are core elements in nursing, and therefore nurses in the rehabilitation departments are pivotal in the prevention of complications. Hence, the frequency of complications is an indicator of nursing care quality, which can be included in nursing-sensitive outcome indicators. To do so, it is necessary to know the frequency of the selected complications. The aim of this study was to quantify complications during the first year after severe TBI. This study included patients 15 years or older who received subacute neurorehabilitation after severe TBI from 2011 to 2015 (N = 469). This is a register-based follow-up study using data from the Danish Head Trauma Database, a national clinical quality database aimed at monitoring and improving the quality of rehabilitation for patients with severe TBI. The following complications were assessed: urinary tract infection, pneumonia, pressure ulcers, joint contractures, and deep venous thrombosis. The prevalence of each complication was calculated at admission, discharge, and 1 year postinjury and for the period from admission and during subacute rehabilitation. In addition, the frequency of complications that certainly developed during subacute rehabilitation was calculated. Complications were compared between age-specific subgroups using multivariable binominal regression analyses. Urinary tract infections (53%) and pneumonia (32%) were the most common complications in the period from admission and during subacute rehabilitation. Pressure ulcers (18%), joint contractures (18%), and deep venous thrombosis (4%) were less frequent. At discharge and 1 year postinjury, the prevalence was less than 4% for all complications, except for joint contractures (16% and 13% at discharge and 1 year postinjury, respectively). The prevalence of complications was high. The findings are important for future quality improvement of the rehabilitation trajectory and for further studies that explore the high frequency of complications.

Patients with ileal conduit urinary diversions are at an increased risk of long-term upper urinary tract (UUT) complications, including anastomotic strictures, infections, and urolithiasis. The reconstructed urinary system poses challenges for endoscopic manipulation. We present and describe our dual-center experience in performing retrograde ureteroscopy to treat or diagnose UUT abnormalities in patients with ileal conduit incontinent diversion. We performed a retrospective analysis of medical records for all patients with previous urinary diversion who underwent retrograde ureteroscopic procedures via the ileal loop in our institutions over a 9 year period (between June 2007 and August 2016). Fifty-four procedures were performed in 36 patients. Mean age was 61 (28-90) years. Average time from diversion to ureteroscopic procedure was 13.0 (0.08-53) years. Stone disease was the most common indication for intervention in 35.2% (19/54) of cases, with a stone-free rate of 78.9% (15/19). Other indications included surveillance of transitional-cell carcinoma in 22.2% (12/54), diagnostic flexible ureteroscopy (fURS) in 20.4% (11/54), stricture management in 11.1% (6/54), removal of encrusted stent/nephrostomy in 7.4% (4/54), urine leak after diversion in 1.9% (1/54), and miscellaneous in 1.9% (1/54). Successful retrograde access was possible in 74% (40/54) of cases. A long and tortuous ileal segment, too difficult to negotiate, was the most common cause of failure to access the UUT. In 13 out of 54 (24.1%) cases, retrograde fURS was combined with simultaneous percutaneous antegrade access. Six patients (11.1%) developed postprocedural pyrexia requiring additional antibiotic therapy, and one (1.9%) patient required embolization of the renal artery for ongoing bleeding. Median length of stay was 1 day (0-55), with 13 (24%) being performed as day-case procedures. Retrograde ureteroscopy in patients with ileal conduits can be technically challenging due to distorted anatomy. This procedure can be safely performed in experienced hands with standard endourological equipment. An antegrade approach can be carried out simultaneously, which may be required in a small number of patients.

Urolithiasis in children occurs with the incidence of 0.1-5%. Risk factors such as metabolic disorders, recurrent urinary tract infections and/or congenital abnormalities of urinary tract are detected in 75-85% of children with urolithiasis. Staghorn calculi is associated with delayed diagnosis and treatment of urinary tract infection caused by specific organisms, which produce the enzyme urease, promoting generation of ammonia and hydroxide from urea. We present two boys with staghorn calculi recognized in 8th and 31st month of age. The reason for performing ultrasonography was urinary tract infection in both boys. The younger child was previously healthy, with no symptoms of urolithiasis, the older one had recurrent urinary tract infections caused by Proteus mirabilis, episodes of anxiety and abdominal pain. Laboratory test and imaging studies excluded congenital abnormalities in the urinary tract and typical metabolic causes of urolithiasis in both boys. Treatment of infection-related stones in the younger child included two extracorporeal shock-wave lithotripsy (ESWL). In the older child, both ESWL and operation were performed. Staghorn calculi were composed of mixtures of magnesium ammonium phosphate (struvite) and calcium carbonate (apatite) and confirmed to be identified as infection-related stones. During follow-up in a nephrology outpatient clinic, values of blood pressure, renal ultrasonography, kidney function test were normal and no symptoms of urinary tract infections were clinically present. In patients with recurrent urinary tract infections, urolithiasis should be taken into consideration. The majority of staghorn calculi is often asymptomatic and can be diagnosed with an ultrasonography study performed routine or during urinary tract infection.

Urinary tract infections (UTIs) are one of the most frequent complications of pregnancy. When the lower UTIs of asymptomatic bacteriuria and cystitis are not eradicated, the subsequent risk of the development of pyelonephritis is increased. The associated decreased maternal morbidity and fetal prematurity are the goals of a screening and treatment program for pregnant women. This clinical article presents information on the etiology, incidence, diagnosis, and management of asymptomatic bacteriuria and cystitis. Nursing implications regarding teaching are included.

Urinary pH as a Risk Factor for Stone Type

NASA Astrophysics Data System (ADS)

Sakhaee, Khashayar

2007-04-01

A high urinary pH is main risk factor for the calcium phosphate stone formation; however, its pathophysiologic mechanism has not been fully understood. The introduction of Topiramate in the treatment of various neurological disorders has been complicated by metabolic acidosis, significant hypocitraturia, elevated urinary pH, and calcium phosphate stone formation. This model provides a probe to investigate the pathophysiologic mechanism of calcium phosphate stone formation and perhaps to develop appropriate countermeasures in the future. On the other hand an unduly acidic urine predisposes one to uric acid nephrolithiasis. Our recent investigation linking low urinary pH, and defective renal ammoniagenesis to insulin resistance provides new knowledge to unfold the pathophysiology of uric acid nephrolithiasis. The metabolic profile leading to uric acid stone may emerge as one of the components of metabolic syndrome.

Protective Role of Sodium-Glucose Co-Transporter 2 Inhibition Against Vascular Complications in Diabetes.

PubMed

Yamagishi, Sho-ichi; Matsui, Takanori

2016-04-01

Diabetic micro- and macroangiopathy are devastating vascular complications that could account for disabilities and high mortality rate in patients with diabetes. Indeed, diabetic nephropathy and retinopathy are the leading causes of end-stage renal failure and acquired blindness, respectively, and atherosclerotic cardiovascular diseases (CVD) accounts for about 60% of death in diabetic subjects. As a result, the average life span of diabetic patients is about 10-15 years shorter than that of non-diabetic subjects. Furthermore, tight blood glucose control might have no more than a marginal impact on CVD in general and on all-cause mortality in particular in diabetes. Therefore, therapeutic strategies that target vascular complications in diabetes need to be developed. Recently, selective inhibition of sodium-glucose co-transporter 2 (SGLT2) has been proposed as a potential therapeutic target for the treatment of patients with diabetes because of low risk of hypoglycemia and no weight gain. Because 90% of glucose filtered by the glomerulus is reabsorbed by a low-affinity/high-capacity SGLT2 expressed in the S1 and S2 segments of the proximal tubule, blockade of SGLT2 promotes urinary glucose excretion and as a result improves hyperglycemia in an insulin-independent manner. Moreover, we have shown that SGLT2-mediated glucose overload to tubular cells could elicit inflammatory and pro-apoptotic reactions in this cell, being directly involved in diabetic nephropathy. In addition, several clinical studies have also shown that SGLT2 inhibitors could reduce blood pressure, body weight, and serum uric acid levels and ameliorate cardiovascular risk in patients with diabetes. This review summarizes the pathophysiological role of SGLT2 in vascular complications in diabetes and its potential therapeutic interventions.

A 10-year-old, entire, male, mixed-breed dog was presented for severe haematuria and stranguria. Ultrasound revealed a large intraluminal urinary bladder blood clot and a prostatic space-occupying lesion. Invasion of the lesion into the prostatic urethra was detected ultrasonographically during compression of the urinary bladder. Post-mortem examination revealed primary prostatic haemangiosarcoma infiltrating the urethra. Haemangiosarcoma should be considered as a rare cause of prostatic mass lesions, haematuria or lower urinary tract signs in dogs.

Medical and Surgical Treatment Modalities for Lower Urinary Tract Symptoms in the Male Patient Secondary to Benign Prostatic Hyperplasia: A Review

Benign prostatic hyperplasia (BPH) with lower urinary tract symptoms (LUTS) is one of the most common ailments affecting aging men. Symptoms typically associated with BPH include weak stream, hesitancy, urgency, frequency, and nocturia. More serious complications of BPH include urinary retention, gross hematuria, bladder calculi, recurrent urinary tract infection, obstructive uropathy, and renal failure. Evaluation of BPH includes a detailed history, objective assessment of urinary symptoms with validated questionnaires, and measurement of bladder function parameters, including uroflowmetry and postvoid residual. In general, treatment of LUTS associated with BPH is based on the effect of the symptoms on quality of life (QOL) and include medical therapy aimed at reducing outlet obstruction or decreasing the size of the prostate. If medical therapy fails or is contraindicated, various surgical options exist. As the elderly population continues to grow, the management of BPH will become more common and important in maintaining patient's QOL. PMID:27582609

To review the indications, procedures, complications, and related treatments of double pigtail stent (DPS) placement as an adjunct for some types of endoscopic and open urologic surgery. From July 1998 to December 2006, 2413 patients aged 8 to 81 years underwent stent placement (2685 total placements). The indications consisted of ureteroscopic lithotripsy (1984 cases), percutaneous nephrolithotomy (329 cases), ureteral incision to remove calculi (71 cases), extracorporeal shockwave lithotripsy for upper urinary tract calculi (145 cases), ureteropelvic junction obstruction (31 cases), ureterocystoneostomy (29 cases), benign ureteral stenosis (52 cases), extrinsic ureteral stenosis (16 cases), and iatrogenic ureteral trauma (28 cases). DPSs were inserted into the ureter by cystoscopy (115 stents), ureteroscopy (2052 stents), percutaneous nephrostomy (393 stents), or open surgery (125 stents), and were kept inside the body for 28 +/- 1.7 days (range 1-193 days). The mean follow-up period was 31 +/- 1.9 days (range 1-123 days). Three hundred sixty-five patients (19.6%) experienced one or more problems during the stenting procedure. The main complications were gross hematuria (385 cases), pain (101 cases), bladder irritation (105 cases), high fever (6 cases), encrustation (53 cases), stent migration (42 cases), and stenosis or restenosis (51 cases). Most of the complications were mild and tolerable, and all were immediately treated appropriately. However, 60 stents had to be removed: 29 for gross hematuria, 18 for pain, 7 for bladder irritation, and 6 for high fever. DPS is a safe and useful adjunct for both endoscopic and open procedures to treat upper urinary tract diseases. Most of the complications of DPS placement can be well managed.

The number of elderly patients with pneumonia is significantly increasing as the populations in many countries age. Although elderly patients with pneumonia are at risk of developing urinary tract infections, no studies have examined the prevalence or the prognostic impact of this complication. The aim of the present study was to investigate the prevalence of comorbid bacterial pyuria and the impact on the prognosis of elderly patients with pneumonia. We retrospectively evaluated 132 patients aged >65 years who were hospitalized for pneumonia and who underwent a urinary sediment test on admission. The background characteristics, laboratory results and treatment regimens were documented, and the risk factors for the complication of bacterial pyuria and its association with 90-day mortality in pneumonia patients were elucidated. A total of 37 (28%) of 132 patients were complicated by bacterial pyuria. The patients with bacterial pyuria were more often women, showed a poorer performance status, were more frequently fed by percutaneous endoscopic gastrostomy, and more frequently used diapers and/or a bladder catheter. Regarding first-line drugs, 82.6% of the patients received beta-lactamase inhibitors and extended-spectrum penicillins. The use of a bladder catheter and a poor performance status were associated with bacterial pyuria. A multivariate analysis showed that a poor performance status was the only factor associated with 90-day mortality. Bacterial pyuria did not affect the prognosis of patients who were treated with penicillin-based regimens. Thus, broad-spectrum antibiotics are not necessarily required for elderly patients with pneumonia complicated by urinary tract infection.

The aim of our study was to assess midurethral sling (MUS) failure rate in the morbidly obese (body mass index [BMI] ≥40 kg/m) population as compared with normal-weight individuals. Our secondary objective was to assess the difference in complication rates. This is a retrospective cohort study. We included all patients who underwent a synthetic MUS procedure from January 1, 2008, to December 31, 2015, in our health system. Failure was defined as reported stress urinary incontinence symptoms or treatment for stress urinary incontinence. Variables collected were BMI; smoking status; comorbidities; perioperative (≤24 hours), short-term (≤30 days), and long-term (>30 days) complications; and follow-up time. Statistics include analysis of variance, χ test, logistic regression, Kaplan-Meier method, and Cox regression. There were 431 patients included in our analysis. Forty-nine patients were in class 3 with a BMI mean of 44.9 ± 5.07 kg/m. Median follow-up time was 52 months (range, 6-119 months). Class 3 obesity (BMI ≥40 kg/m) was the only group that had an increased risk of failure when compared with the normal-weight group (P = 0.03; odds ratio, 2.47; 95% confidence interval, 1.09-5.59). Obesity was not a significant predictor of perioperative, short-term, or long-term postoperative complications (P = 0.19, P = 0.28, and P = 0.089, respectively) after controlling for other comorbidities. Patients in the class 3 obesity group who are treated with an MUS are 2 times as likely to fail when compared with those in the normal-weight category on long-term follow-up with similar low complication rates.

To assess significance of urinary neutrophil gelatinase-associated lipocalin (NGAL) for predicting hospital complications in subjects with ischemic heart disease (IHD) after coronary artery bypass grafting (CABG). The study included 720 subjects who underwent CABG between 03/2011 and 04/2012. Blood serum creatinine level, glomerular filtration rate (GFR) (MDRD formula) and NGAL concentration were measured before and on day 7 after CABG. The following unfavorable outcomes of operative intervention: myocardial infarction (MI), stroke or transient ischemic attack, acute or progression of chronic renal disease, remediastinotomy were registered during in-hospital period. Additive EuroSCORE was calculated for all patients. There were no significant differences in serum creatinine level and GFR both before and on day 7 after CABG between groups of patients with different risk assessed by EuroSCORE, and with complicated and uncomplicated postoperative course. Urine NGAL level before and on day 7 after CABG was significantly higher in high and medium compared with low EuroSCORE risk groups. Preoperative NGAL urine level was significantly higher in patients with than in those without MI or stroke after CABG. NGAL urine level was also higher in patients with development of acute renal failure (ARF) compared with those without ARF. Both pre- and postoperative NGAL urine levels were higher in patients with unfavorable outcome while there were no significant differences in serum creatinine levels and CRF between patients with favorable and unfavorable outcomes. Preoperative measurement of urinary NGAL - a preclinical marker of acute kidney injury - allowed to predict more accurately the hospital risk of development of adverse cardiovascular and renal complications of CABG.

Purpose This study evaluated the use of adding morphine to bupivacaine in spinal anesthesia for pain control in patients who underwent an open hemorrhoidectomy. Methods Forty patients were prospectively selected for an open hemorrhoidectomy at the same institution and were randomized into two groups of 20 patients each: group 1 had a spinal with 7 mg of heavy bupivacaine associated with 80 µg of morphine (0.2 mg/mL). Group 2 had a spinal with 7 mg of heavy bupivacaine associated with distilled water, achieving the same volume of spinal infusion as that of group 1. Both groups were prescribed the same pain control medicine during the postoperative period. Pain scores were evaluated at the anesthetic recovery room and at 3, 6, 12, and 24 hours after surgery. Postoperative complications, including pruritus, nausea, headaches, and urinary retention, were also recorded. Results There were no anthropometric statistical differences between the two groups. Pain in the anesthetic recovery room and 3 hours after surgery was similar for both groups. However, pain was better controlled in group 1 at 6 and 12 hours after surgery. Although pain was better controlled for group 1 after 24 hours of surgery, the difference between the groups didn't achieved statistical significance. Complications were more common in group 1. Six patients (6/20) presented coetaneous pruritus and 3 with (3/20) urinary retention. Conclusion A hemorrhoidectomy under a spinal with morphine provides better pain control between 6 and 12 hours after surgery. However, postoperative complications, including cutaneous pruritus (30%) and urinary retention (15%), should be considered as a negative side of this procedure. PMID:24999465

We report a 1-year update of functional urinary and sexual recovery, oncologic outcomes and postoperative complications in patients who completed a randomized controlled trial comparing posterior (Retzius sparing) with anterior robot-assisted radical prostatectomy. A total of 120 patients with clinically low-intermediate risk prostate cancer were randomized to undergo robot-assisted radical prostatectomy via the posterior and anterior approach in 60 each. Surgery was performed by a single surgical team at an academic institution. An independent third party ascertained urinary and sexual function outcomes preoperatively, and 3, 6 and 12 months after surgery. Oncologic outcomes consisted of positive surgical margins and biochemical recurrence-free survival. Biochemical recurrence was defined as 2 postoperative prostate specific antigen values of 0.2 ng/ml or greater. Median age of the cohort was 61 years and median followup was 12 months. At 12 months in the anterior vs posterior prostatectomy groups there were no statistically significant differences in the urinary continence rate (0 to 1 security pad per day in 93.3% vs 98.3%, p = 0.09), 24-hour pad weight (median 12 vs 7.5 gm, p = 0.3), erection sufficient for intercourse (69.2% vs 86.5%) or postoperative Sexual Health Inventory for Men score 17 or greater (44.6% vs 44.1%). In the posterior vs anterior prostatectomy groups a nonfocal positive surgical margin was found in 11.7% vs 8.3%, biochemical recurrence-free survival probability was 0.84 vs 0.93 and postoperative complications developed in 18.3% vs 11.7%. Among patients with clinically low-intermediate risk prostate cancer randomized to anterior (Menon) or posterior (Bocciardi) approach robot-assisted radical prostatectomy the differences in urinary continence seen at 3 months were muted at the 12-month followup. Sexual function recovery, postoperative complication and biochemical recurrence rates were comparable 1 year postoperatively.

Especially complicated, renal lithiasis contributes to the general inflammatory syndrome development that interferes with nonspecific, humoral and cellular immune system. The surgical treatment of nephrolithiasis is closely related to drug therapy of urinary infection, one of the reasons being the reduction of the immune status. The work is performed by evaluating the immunological status preoperatively in 58 patients with complicated lithiasis. The analysis of the status in these patients demonstrated that complicated urolithiasis results in significant changes in the immune system, these changes being expressed at the cellular and humoral level of immunity.

A thorough account is given of the complications of embolization techniques in nonneurovascular areas, including hepatic infarction, renal and splenic abscess formation. Infarction of the urinary bladder, gallbladder, stomach, and bowel are discussed. Suggestions are offered to prevent complications from embolization where possible. Specific agents for embolization are detailed and their relative merits are compared; ethyl alcohol has recently gained popularity for treating esophageal varices and infarcting renal tumors. Care is advocated when using alcohol in the renal arteries; employing this agent is currently contraindicated in the celiac and mesenteric arteries. Coils and balloon systems are also described along with their potential complications.

The intrarenal renin-angiotensin system (iRAS) is implicated in the pathogenesis of hypertension, chronic kidney disease and diabetic nephropathy. Urinary angiotensinogen (uAGT) levels reflect the activity of the iRAS and are altered in women with preeclampsia. Since Indigenous Australians suffer high rates and early onset of renal disease, we hypothesised that Indigenous Australian pregnant women, like non-Indigenous women with pregnancy complications, would have altered uAGT levels. The excretion of RAS proteins was measured in non-Indigenous and Indigenous Australian women with uncomplicated or complicated pregnancies (preeclampsia, diabetes/gestational diabetes, proteinuria/albuminuria, hypertension, small/large for gestational age, preterm birth), and in non-pregnant non-Indigenous women. Non-Indigenous pregnant women with uncomplicated pregnancies, had higher uAGT/creatinine levels than non-Indigenous non-pregnant women (P < 0.01), and levels increased as pregnancy progressed (P < 0.001). In non-Indigenous pregnant women with pregnancy complications, uAGT/creatinine was suppressed in the third trimester (P < 0.01). In Indigenous pregnant women with uncomplicated pregnancies, there was no change in uAGT/creatinine with gestational age and uAGT/creatinine was lower in the 2nd and 3rd trimesters than in non-Indigenous pregnant women with uncomplicated pregnancies (P < 0.03, P < 0.007, respectively). The uAGT/creatinine ratios of Indigenous women with uncomplicated or complicated pregnancies were the same. A decrease in uAGT/creatinine with advancing gestational age was associated with increased urinary albumin/creatinine, as is seen in preeclampsia, but it was not specific for this disorder. The reduced uAGT/creatinine in Indigenous pregnant women may reflect subclinical renal dysfunction which limits the ability of the kidney to maintain sodium balance and could indicate an increased risk of pregnancy complications and/or future renal disease.

This study aimed to identify patient characteristics associated with low urinary creatinine in morning spot urine and investigate its association with clinical outcome. Twenty-four-hour creatinine excretion is an established marker of muscle mass in heart failure and other populations. Spot urine creatinine might be an easy obtainable, cheap marker of muscle wasting and prognosis in heart failure (HF) patients. Spot urine creatinine concentration was measured in 2130 patients included in the GISSI-HF trial. We evaluated the prognostic value of urinary creatinine and its relation with clinical variables. Median spot urinary creatinine was 0.80 (IQR 0.50-1.10) g/L. Lower spot urinary creatinine was associated with older age, smaller height and weight, higher NYHA class, worse renal function and more frequent spironolactone and diuretic use (all P<.02). During a median follow-up of 2.8 years, 655 patients (31%) experienced the combined endpoint of all-cause mortality or HF hospitalization. Lower urinary creatinine was independently associated with an increased risk of all-cause mortality or HF hospitalization (HR, 1.59 [1.21-2.08] per log decrease, P=.001), and all-cause mortality (HR, 1.75 [1.25-2.45] per log decrease, P=.001). Lower urinary creatinine, measured in morning spot urine in patients with chronic HF, is associated with worse renal function, smaller body size, more severe HF and is independently associated with an increased risk of all-cause death and HF hospitalization.

Urinary tract infection in the renal transplant patient.

PubMed

de Souza, Ruth M; Olsburgh, Jonathon

2008-05-01

Urinary tract infection (UTI) is the most common type of bacterial infection contracted by recipients of renal allografts in the post-transplantation period. Fungi and viruses can also cause UTIs, but infections caused by these organisms are less common than those caused by bacteria. Both the lower and upper urinary tract (encompassing grafted or native kidneys) can be affected. Factors that might contribute to the development of UTIs include excessive immunosuppression, and instrumentation of the urinary tract (e.g. urethral catheters and ureteric stents). Antimicrobials are the mainstays of treatment and should be accompanied by minimization of immunosuppression when possible. The use of long-term antimicrobial prophylaxis is controversial, however, as it might increase the likelihood of infective organisms becoming resistant to treatment. There are conflicting data on the associations of post-transplantation UTI with graft and patient survival.

Transient urinary retention and chronic neuropathic pain associated with genital herpes simplex virus infection.

Genital herpes (GH) causes genital ulcer disease, severe transient pain, and often paresthesias. Whether or not GH can cause urinary retention or chronic neuropathic pain is not well known. We present two immunocompetent patients with GH associated with neuropathic symptoms. We also review the literature on GH and associated neurologic problems. Patient 1 had primary herpes simplex virus (HSV)-2 infection with transient urinary retention and chronic bilateral neuropathic pain in the sacral area. Patient 2 had recurrent HSV-1 associated with unitaleral chronic neuropathic pain in the sacral area. Although transient urinary retention associated with GH is not uncommon, chronic neuropathic pain has not been reported previously. Our cases show that chronic neuropathic pain, that is "pain initiated or caused by a primary lesion or dysfunction in the nervous system," can follow genital HSV infection.

We assessed the effectiveness and durability of 532 nm laser photovaporization with GreenLight XPS in men with and without preoperative urinary retention. From 2010 to 2017 we prospectively studied men who underwent photovaporization of the prostate (PVP) for obstructive lower urinary tract symptoms (LUTS) secondary to BPH. The cohort was retrospectively divided into those with catheter dependent retention and those with elective PVP. Primary endpoints were catheter-free rate and improvement in quality of life (QoL) scores, international prostate symptom score (IPSS), maximum urinary flow rate (Qmax), and postvoid residual (PVR). The secondary endpoints of the study were complication outcomes as defined by the standardized Clavien-Dindo grading system. One hundred thirty-seven men with preoperative retention and 195 men without preoperative retention underwent PVP. Men with preoperative retention were older (70 years vs 66 years; p < 0.001), had a higher American Society of Anesthesiology (ASA) score, and had a higher prevalence of neurologic disease (8% vs 2.6%; p = 0.04). These men also had a larger prostate volume (76 cc vs 69 cc; p < 0.001) and higher prostate specific antigen (5 ng/mL vs 2.7 ng/mL; p < 0.001) than those without retention. Patients with preoperative retention also had higher preoperative baseline IPSS and QoL score. After PVP they improved to values similar to those without retention, with durability up to 24 months. After PVP, men in preoperative retention had similar rates to fail their first void trial (18.2% vs 10.3%, p = 0.053). There was a 96% catheter-free rate in the men with preoperative retention. The rate of complication was higher in the nonretention group, specifically at 90 days (35.4% vs 21.2%; p = 0.009), with almost all the complications being Clavien-Dindo grade 2. PVP is an effective, safe, and durable treatment for men in acute urinary retention (AUR) with a catheter-free rate of 96%. The improvement is similar to those who did not present in AUR.

Urinary tract infection (UTI) is common in young children and may cause pyelonephritis and renal scarring. Long-term complications from renal scarring are low. The role of imaging is to evaluate for underlying urologic abnormalities and guide treatment. In neonates there is increased risk for underlying urologic abnormalities. Evaluation for vesicoureteral reflux (VUR) may be appropriate especially in boys because of higher prevalence of VUR and to exclude posterior urethral valve. In children older than 2 months with first episode of uncomplicated UTI, there is no clear benefit of prophylactic antibiotic. Ultrasound is the only study that is usually appropriate. After the age of 6 years, UTIs are infrequent. There is no need for routine imaging as VUR is less common. In children with recurrent or complicated UTI, in addition to ultrasound, imaging of VUR is usually appropriate. Renal cortical scintigraphy may be appropriate in children with VUR, as renal scarring may support surgical intervention. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment. Copyright © 2017 American College of Radiology.

Acute complicated pyelonephritis (ACP) is an upper urinary tract infection associated with coexisting urinary tract abnormalities or medical conditions that could predispose to serious outcomes or treatment failures. Although CT and magnetic resonance imaging (MRI) are frequently used in patients with ACP, the clinical value of 18 F-fluorodeoxyglucose positron emission tomography and computed tomography (FDG PET/CT) has not been systematically investigated. This single-center retrospective study was designed to evaluate the potential usefulness of FDG PET/CT in patients with ACP. Thirty-one adult patients with ACP who underwent FDG PET/CT were examined. FDG PET/CT imaging characteristics, including tracer uptake patterns, kidney volumes, and extrarenal imaging findings, were reviewed in combination with clinical data and conventional imaging results. Of the 31 patients, 19 (61%) showed focal FDG uptake. The remaining 12 study participants showed a diffuse FDG uptake pattern. After volumetric approximation, the affected kidneys were found to be significantly enlarged. Patients who showed a focal uptake pattern had a higher frequency of abscess formation requiring drainage. ACP patients showing diffuse tracer uptake patterns had a more benign clinical course. Seven patients had suspected extrarenal coinfections, and FDG PET/CT successfully confirmed the clinical suspicion in five cases. FDG PET/CT was as sensitive as CT in identifying the six patients (19%) who developed abscesses. Notably, FDG PET/CT findings caused a modification to the initial antibiotic regimen in nine patients (29%). FDG PET/CT may be clinically useful in the assessment of patients with ACP who have a progressive disease course.

Subcutaneous penile injection of various oils for penile augmentation has been described among men in Laos. We have now treated three Laotian immigrants with penile disfigurement secondary to sclerosing lipogranulomas, also known as paraffinoma, induced by injection of a mineral oil compound marketed as "1Super Extenze," which they purchased in the United States. This series describes the clinical course and management of complications associated with the use of "1Super Extenze" in three Laotian men. Surgeons excised all grossly affected tissue and performed reconstruction using skin grafting, Z-plasty, and tissue advancement, respectively. Tissue from the penile shaft of each patient and a local lymph node in one patient was examined microscopically. Mass spectroscopy was performed on an aliquot of "1Super Extenze." Urinary function, sexual function, and cosmesis of the three reported cases, chemical composition of "1Super Extenze," and microscopic analysis of penile and regional lymphatic tissue. Short-term cosmetic and functional outcomes were acceptable after surgical intervention. Histologic findings consistent with sclerosing lipogranulomas were seen in specimens from affected subcutaneous and lymphatic tissue. "1Super Extenze" proved to be composed of mineral oil with tocopherol acetate (vitamin E). Injection of "1Super Extenze" into the penile shaft results in sclerosing lipogranulomas, which can cause severe sexual and urinary complications. Surgical resection of all grossly involved tissue with appropriate reconstruction can mitigate these problems. This series supports previous recommendations in the literature that men should avoid the use of non-medical foreign bodies and fillers as means of penile augmentation. © 2010 International Society for Sexual Medicine.

Isolated ruptures of the urinary bladder following minor traumas are a rare abdominal lesion. Diagnosis and treatment are a challenge to emergency physicians and surgeons. This case shows a 46-year-old patient admitted for a minor brain injury after falling during an episode of alcoholic intoxication. Ultrasound and CT scan of the abdomen showed intraabdominal fluid without a parenchymatous lesion. Also a hematuria was significant. The retrograde cystography showed intraabdominal contrast agent. The rupture of the urinary bladder was confirmed by laparoscopy and was intracorporal sutured in double layer technique. Without any postoperative complications the patient was discharged after 4 days. The retrograde cystography after 10 days showed no leckage and the urinary catheter could be removed.

The melamine-contaminated milk powder incidence occurred in China in 2008. Many studies have been published regarding the epidemiology, clinical symptoms, diagnosis and treatment of melamine-related urinary stones. The objective of this study is to follow-up the effects of melamine-contaminated milk powder consumption on kidney and body growth in children with melamine-related urinary stones 4 years ago. One hundred and one children with melamine-related urinary stones were followed up by urinalysis, renal function tests and urinary ultrasonography. The data of body weight and height, clinical signs and complications were collected. Eighty normal children without the history of consuming melamine-contaminated milk powder were collected as controls. Eighty-one children with melamine-related urinary stones were successfully followed up. Of 45 cases with melamine-related urinary stones treated conservatively after discharge, 34 disappeared completely, 6 dissolved partially, 1 increased in size and 4 did not change at 4 years follow-up. The percentages of under-height and under-weight infants were significantly higher in melamine-related urinary stones group compared to the controls, respectively (p < 0.05). Routine blood, renal and bladder function tests as well as urinalysis were normal in all children. No urological tumors were detected. No noticeable impact of melamine-related urinary stones on kidney and bladder was found at 4 years follow-up. However, whether or not melamine-related urinary stones had effect on body growth needs follow-up in future.

This article is a report of a study of the effects of a pelvic floor muscle exercise programme on the severity of stress urinary incontinence in pregnant women. Pregnancy is main risk factor for the development of stress urinary incontinence. Stress urinary incontinence can be cured by pelvic floor muscle exercise which is a safe inexpensive treatment with no complications and does not require the use of instruments. A quasi-experimental study, pre-post test with control group design was used at the antenatal care unit in a tertiary care hospital between June and October of 2006. The participants were 66 pregnant women who had stress urinary incontinence with gestational ages of 20-30 weeks. The main outcome measure was severity of stress urinary incontinence which comprised frequency and amount of urine leakage and perceived severity of stress urinary incontinence. After the experimental group's participation in the pelvic floor muscle exercise programme, the frequency and amount of urine leakage and the score of perceived stress urinary incontinence severity were significantly lower than the same scores before participation in the programme. In addition, women in the experimental group had frequency and volume of urine leakage, and score of perceived stress urinary incontinence severity after participation significantly lower than those in the control group. The 6-week pelvic floor muscle exercise programme was able to decrease the severity of symptoms in pregnant women with stress urinary incontinence. © 2011 Blackwell Publishing Ltd.

Traumatic brain injury (TBI) is an important health issue with high mortality. Various complications of physiological and cognitive impairment may result in disability or death after TBI. Grouping of these complications could be treated as integrated post-TBI syndromes. To improve risk estimation, grouping TBI complications should be investigated, to better predict TBI mortality. This study aimed to estimate mortality risk based on grouping of complications among TBI patients. Taiwan's National Health Insurance Research Database was used in this study. TBI was defined according to the International Classification of Diseases, Ninth Revision, Clinical Modification codes: 801-804 and 850-854. The association rule data mining method was used to analyze coexisting complications after TBI. The mortality risk of post-TBI complication sets with the potential risk factors was estimated using Cox regression. A total 139,254 TBI patients were enrolled in this study. Intracerebral hemorrhage was the most common complication among TBI patients. After frequent item set mining, the most common post-TBI grouping of complications comprised pneumonia caused by acute respiratory failure (ARF) and urinary tract infection, with mortality risk 1.55 (95% C.I.: 1.51-1.60), compared with those without the selected combinations. TBI patients with the combined combinations have high mortality risk, especially those aged <20 years with septicemia, pneumonia, and ARF (HR: 4.95, 95% C.I.: 3.55-6.88). We used post-TBI complication sets to estimate mortality risk among TBI patients. According to the combinations determined by mining, especially the combination of septicemia with pneumonia and ARF, TBI patients have a 1.73-fold increased mortality risk, after controlling for potential demographic and clinical confounders. TBI patients aged<20 years with each combination of complications also have increased mortality risk. These results could provide physicians and caregivers with important information to increase their awareness about sequences of clinical syndromes among TBI patients, to prevent possible deaths among these patients.

[Clinical laboratory examination of diabetic patients in conjunction with metabolic syndrome].

Diabetic patients tend to show a reduced QOL because of macrovascular complications such as cerebral and myocardial infarction, as well as marked microvascular complications. It is important for the prevention and amelioration of these complications to diagnose diabetes mellitus (DM) early and effectively control glycemia, the blood pressure, lipids, and body weight. We examine fasting plasma glucose (FPG) and HbA1c for a diagnosis of diabetes at any time, but examine 75gOGTT for impaired glucose tolerance or DM. Examination to be necessary for a pathologic classification of DM is islet-associated antibody, namely, GAD antibody, IA-2 antibody and the measurement of IRI, blood/urinary C-peptide to evaluate insulin secretory ability. HOMA-R is an index of insulin resistance, and HOMA-beta is an index of insulin secretory ability which can be calculated from FPG and IRI, but we need to be aware that the insulin secretory ability of the patient may have decreased already. HbA1c is a standard index of glycemic control, but glycoalbumin measurement is suitable for disease states such as anemia and liver cirrhosis, and 1,5-anhydroglucitol is suitable for detecting changes in levels of urinary glucose. Examinations necessary for the evaluation of diabetic nephropathy are microalbumin and 24hr Ccr in the urine, but eGFR has been recently recommended instead of 24hr Ccr. We measure small dense LDL-C, RLP-C, and Lp (a) as well as conduct conventional lipid analyses for dislipidemia combined with DM for qualitative as well as quantitative data. Metabolic syndrome is caused by the life habits of overeating and lack of exercise, leading to atherosclerotic disease, because insulin resistance advances from visceral fat accumulation. TNF-alpha and leptin levels as insulin resistance advances and adiponectin levels as insulin resistance improves are measured as adipocytokines secreted by visceral fat tissue.

Increased incidence of urolithiasis and bacteremia during Proteus mirabilis and Providencia stuartii coinfection due to synergistic induction of urease activity.

Catheter-associated urinary tract infections (CaUTIs) are the most common hospital-acquired infections worldwide and are frequently polymicrobial. The urease-positive species Proteus mirabilis and Providencia stuartii are two of the leading causes of CaUTIs and commonly co-colonize catheters. These species can also cause urolithiasis and bacteremia. However, the impact of coinfection on these complications has never been addressed experimentally. A mouse model of ascending UTI was utilized to determine the impact of coinfection on colonization, urolithiasis, and bacteremia. Mice were infected with P. mirabilis or a urease mutant, P. stuartii, or a combination of these organisms. In vitro experiments were conducted to assess growth dynamics and impact of co-culture on urease activity. Coinfection resulted in a bacterial load similar to monospecies infection but with increased incidence of urolithiasis and bacteremia. These complications were urease-dependent as they were not observed during coinfection with a P. mirabilis urease mutant. Furthermore, total urease activity was increased during co-culture. We conclude that P. mirabilis and P. stuartii coinfection promotes urolithiasis and bacteremia in a urease-dependent manner, at least in part through synergistic induction of urease activity. These data provide a possible explanation for the high incidence of bacteremia resulting from polymicrobial CaUTI.

Since pathologies and complications occurring during pregnancy and/or during labour may cause adverse outcomes for both newborns and mothers, there is a growing interest in metabolomic applications on pregnancy investigation. In fact, metabolomics has proved to be an efficient strategy for the description of several perinatal conditions. In particular, this study focuses on premature rupture of membranes (PROM) in pregnancy at term. For this project, urine samples were collected at three different clinical conditions: out of labour before PROM occurrence (Ph1), out of labour with PROM (Ph2), and during labour with PROM (Ph3). GC-MS analysis, followed by univariate and multivariate statistical analysis, was able to discriminate among the different classes, highlighting the metabolites most involved in the discrimination.

To demonstrate a benefit in diminished adverse events such as hypotension and hematuria with gradual drainage of the bladder when compared to rapid decompression in patients with acute urinary retention (AUR) due to benign prostatic hyperplasia in a case-control study. Sixty-two patients matched our selection criteria presenting with AUR. They were divided into two groups - the first was managed by rapid drainage of the bladder, the second was managed by gradual drainage through a urethral catheter (The first 100 mL immediately evacuated, then the rest evacuated gradually over 2 h). The mean age was 64.4 and 63.2 years in the first and second group, respectively. Diagnosed cause was benign hyperplasia of the prostate. Hematuria occurred in two patients in the first group and none in the second group. The two cases of hematuria were mild and treated conservatively. After the relief of the obstruction, the mean blood pressure was noticed to decrease by 15 mmHg and 10 mmHg in the first and second group, respectively, however, no one developed significant hypotension. Pain relief was achieved after complete drainage in the first group and after the evacuation of 100 mL in the second group. We conclude that there is no significant difference between rapid and gradual decompression of the bladder in patients with AUR. Hematuria and hypotension may occur after rapid decompression of the obstructed urinary bladder, but these complications are rarely clinically significant.

The National Surgical Quality Improvement Program is aimed at preventing perioperative complications. An online calculator was recently published, but the primary studies used limited gynecologic surgery data. The purpose of this study was to evaluate the performance of the National Surgical Quality Improvement Program Universal Surgical Risk Calculator (URC) on the patients of a gynecologic oncology service. We reviewed 628 consecutive surgeries performed by our gynecologic oncology service between July 2012 and June 2013. Demographic data including diagnosis and cancer stage, if applicable, were collected. Charts were reviewed to determine complication rates. Specific complications were as follows: death, pneumonia, cardiac complications, surgical site infection (SSI) or urinary tract infection, renal failure, or venous thromboembolic event. Data were compared with modeled outcomes using Brier scores and receiver operating characteristic curves. Significance was declared based on P < 0.05. The model accurately predicated death and venous thromboembolic event, with Brier scores of 0.004 and 0.003, respectively. Predicted risk was 50% greater than experienced for urinary tract infection; the experienced SSI and pneumonia rates were 43% and 36% greater than predicted. For any complication, the Brier score 0.023 indicates poor performance of the model. In this study of gynecologic surgeries, we could not verify the predictive value of the URC for cardiac complications, SSI, and pneumonia. One disadvantage of applying a URC to multiple subspecialties is that with some categories, complications are not accurately estimated. Our data demonstrate that some predicted risks reported by the calculator need to be interpreted with reservation.

Angiotensin-converting enzyme inhibitor-related angioedema (ACEI-RA) is a well-described condition, yet isolated genital ACEI-RA is a little-known entity. A case of isolated genital angioedema is presented with photographic documentation. Possible complications and therapeutic options are discussed. A 71-year-old man presented with painless, nonpruritic genital swelling of 4 h duration. Medical history included peptic ulcer disease, hypertension, and benign prostatic hypertrophy. His medications included pantoprazole, hydrochlorothiazide, and lisinopril, which he had been taking for 3 years without any recent change in dosing. He was otherwise asymptomatic and previously had been in good health generally. The physical examination was positive only for diffuse, soft, nonpitting edema isolated to the scrotum and uncircumcised penis. The foreskin was only partially retractable. Urinalysis was normal. All symptoms resolved without complications within 48 h of discontinuing lisinopril and had not recurred at follow-up 4 months later. All cases of ACEI-RA isolated to the genitals that have been reported in the literature resolved without complications. ACEI-RA can present as isolated swelling of the genitals and is a potential cause of genital swelling. Patients who have no evidence of airway compromise, paraphimosis, or urinary retention from complications such as phimosis can be safely discharged with instructions to discontinue the offending agent and to return in case of development of the aforementioned conditions.

Bushnell, D.L.; Wilson, D.G.; Lieberman, L.M.

Radionuclide scintigraphy is a safe and accurate means of detecting postoperative urologic complications in renal transplant recipients. Early identification of urinary leakage coupled with aggressive intervention significantly reduces the associated morbidity and mortality. Perivesical extravasate may be difficult to distinguish from adjacent or nearby bladder activity on scintiscan. Clarification of actual bladder contour and determination of its exact location within the pelvis may resolve such uncertainties. We describe imaging techniques that define the anatomic extent of the bladder and demonstrate our scintigraphic assessment of perivesical extravasation.

The aim of this retrospective study was to analyze the nephrourologic pathology in 72 girls with Turner syndrome followed between 1989 and 2008 at Garrahan Hospital. The prevalence of nephrourologic involvement was 33% (24 patients). The most frequent findings were urinary system malformations, isolated (10 pacientes, 42%) or associated with renal malformations (9 patients, 37%); 5 patients (21%) had only renal malformations. Fifty percent of patients developed complications (8 urinary tract infection, 2 proteinuria and 2 arterial hypertension); however, none progressed to chronic renal failure. The prevalence of nephrourologic involvement was 33% and a half of these girls developed complications, our findings show the need of routine nephrological follow-up of girls with Turner syndrome and nephrourologic malformations.

Retzius space reconstruction following transperitoneal laparoscopic robot-assisted radical prostatectomy: does it have any added value?

Retzius space sparing (RSS) during laparoscopic robot-assisted radical prostatectomy (RALP) has been offered as an approach that reduces perioperative complications and enables faster gaining of full urinary continence due to bladder anatomy preservation. Retro and transperitoneal techniques have been proposed, whereby RSS has been implemented. We sought to explore whether Retzius space reconstruction (RSR) following transperitoneal RALP will be an advantageous step as well. A prospective registry database of 102 consecutive transperitoneal RALP cases performed by a single surgeon was reviewed. The Retzius space had been opened by dissecting the bladder away from the anterior abdominal wall to the level of both internal rings. In the last 51 cases (RSR group), the peritoneal layer had been sutured back, thus repositioning the bladder back to the anterior abdominal wall and reconstructing the Retzius space. Perioperative factors were analyzed and compared between the two groups. Demographic and perioperative data did not differ between the two groups. RSR group demonstrated shorter length of stay (LOS) compared with the control group (p = 0.01), as well as faster urinary continence recovery (i.e., 0 pads) (p = 0.01). Moreover, lower numbers of Clavien-Dindo class 3 complications and 12 mm port-site hernias (p = 0.03) were seen in the RSR group compared with the control group. RSR following transperitoneal RALP is a simple and efficient step that potentially reduces early and late post-operative complications, shortens LOS and accelerates full urinary continence.

Diabetes mellitus causes diabetic bladder dysfunction. We identified the pathogenic roles of polyuria and hyperglycemia in diabetic bladder dysfunction in rats. A total of 72 female Sprague-Dawley® rats were divided into 6 groups, including age matched controls, and rats with sham urinary diversion, urinary diversion, streptozotocin induced diabetes mellitus after sham urinary diversion, streptozotocin induced diabetes mellitus after urinary diversion and 5% sucrose induced diuresis after sham urinary diversion. Urinary diversion was performed by ureterovaginostomy 10 days before diabetes mellitus induction. Animals were evaluated 20 weeks after diabetes mellitus or diuresis induction. We measured 24-hour drinking and voiding volumes, and cystometry. Bladders were harvested to quantify smooth muscle, urothelium and collagen. We measured nitrotyrosine and Mn superoxide dismutase in the bladder. Diabetes and diuresis caused increases in drinking and voiding volume, and bladder weight. Bladder weight decreased in the urinary diversion group and the urinary diversion plus diabetes group. The intercontractile interval, voided volume and compliance increased in the diuresis and diabetes groups, decreased in the urinary diversion group and further decreased in the urinary diversion plus diabetes group. Total cross-sectional tissue, smooth muscle and urothelium areas increased in the diuresis and diabetes groups, and decreased in the urinary diversion and urinary diversion plus diabetes groups. As a percent of total tissue area, collagen decreased in the diuresis and diabetes groups, and increased in the urinary diversion and urinary diversion plus diabetes groups. Smooth muscle and urothelium decreased in the urinary diversion and urinary diversion plus diabetes groups. Nitrotyrosine and Mn superoxide dismutase increased in rats with diabetes and urinary diversion plus diabetes. Polyuria induced bladder hypertrophy, while hyperglycemia induced substantial oxidative stress in the bladder, which may have a pathogenic role in late stage diabetic bladder dysfunction.

There was no significant difference between groups regarding age, gender, body mass index, American Society of Anesthesiologists score, type of surgery, operative time, operative complications and intraoperative or postoperative transfusion. Estimated blood loss was lower using reduced-port approach. VAPS at postoperative day one was significantly lower for 2-port approach and so was the length of stay. Patient satisfaction with the wound was higher for 2-port surgery. Differences were not observed in number and severity of postoperative complications. Urological reconstructive operations can be safely performed using the hybrid laparoendoscopic single-site umbilical approach, resulting in lower blood loss, higher patient satisfaction and lower postoperative pain, which also facilitate earlier hospital discharge, than the same reconstructive procedures performed through multiport conventional laparoscopy. © 2016 S.

Variation in care within and across geographic areas remains poorly understood. The goal of this article was to examine whether physician social networks-as defined by shared patients-are associated with rates of complications after radical prostatectomy. In five cities, we constructed networks of physicians on the basis of their shared patients in 2004-2005 Surveillance, Epidemiology and End Results-Medicare data. From these networks, we identified subgroups of urologists who most frequently shared patients with one another. Among men with localized prostate cancer who underwent radical prostatectomy, we used multilevel analysis with generalized linear mixed-effect models to examine whether physician network structure-along with specific characteristics of the network subgroups-was associated with rates of 30-day and late urinary complications, and long-term incontinence after accounting for patient-level sociodemographic, clinical factors, and urologist patient volume. Networks included 2677 men in five cities who underwent radical prostatectomy. The unadjusted rate of 30-day surgical complications varied across network subgroups from an 18.8 percentage-point difference in the rate of complications across network subgroups in city 1 to a 26.9 percentage-point difference in city 5. Large differences in unadjusted rates of late urinary complications and long-term incontinence across subgroups were similarly found. Network subgroup characteristics-average urologist centrality and patient racial composition-were significantly associated with rates of surgical complications. Analysis of physician networks using Surveillance, Epidemiology and End Results-Medicare data provides insight into observed variation in rates of complications for localized prostate cancer. If validated, such approaches may be used to target future quality improvement interventions. Copyright © 2014 International Society for Pharmacoeconomics and Outcomes Research (ISPOR).

ABSTRACT Objective Although catatonia can occur secondary to a general medical condition, catatonia itself has been known to lead to various medical compolications. Although case reports on the association of catatonia with subsequent medical complications have been documented, no comprehensive large-scale study has been performed. To investigate specific medical complications after catatonia, we conducted a retrospective cohort study of specific medical complications of schizophrenia patients with catatonia. Methods The 1719 schizophrenia inpatients in our study were categorized into two groups: the catatonia group, i.e., those who exhibited catatonic stupor while they were hospitalized, and the noncatatonia group, i.e., those who never exhibited catatonic stupor. Differences between the two groups in the occurrence of subsequent medical complications were examined using linear and logistic regression analyses, and models were adjusted for potentially confounding factors. Results The catatonia group had an increased risk for mortality (odds ratio = 4.8, 95% confidence interval = 2.0–10.6, p < .01) and certain specific medical complications, i.e., pneumonia, urinary tract infection, sepsis, disseminated intravascular coagulation, rhabdomyolysis, dehydration, deep venous thrombosis, pulmonary embolism, urinary retention, decubitus, arrhythmia, renal failure, neuroleptic malignant syndrome, hypernatremia, and liver dysfunction (all p values < .01, except for deep venous thrombosis, p = .04 in the multiple linear regression analysis). Conclusions Catatonic stupor in schizophrenia substantially raises the risk for specific medical complications and mortality. Hyperactivity of the sympathetic nervous system, dehydration, and immobility, which are frequently involved in catatonia, might contribute to these specific medical complications. In catatonia, meticulous care for both mental and medical conditions should be taken to reduce the risk of adverse medical consequences. PMID:29521882

The arterial ligation during elective laparoscopic sigmoidectomy for diverticular disease can affect genito-urinary function injuring the superior hypogastric plexus, and can weaken the distal colonic stump arterial perfusion. Ligation of the inferior mesenteric artery distal to the left colic artery or the complete preservation of the inferior mesenteric artery can therefore be compared in terms of preservation of the descending sympathetic fibres running along the aorta to the rectum resulting in a different post operative genito urinary function. From January 2015 to March 2016, 66 patients underwent elective laparoscopic sigmoidectomy for diverticular disease among two enrolling hospitals. In one centre 35 patients underwent laparoscopic sigmoidectomy with the ligation of the inferior mesenteric artery distal to the left colic artery (low ligation). In the other centre 31 patient were operated on the same procedure with complete inferior mesenteric artery preservation (IMA preservation). There was no difference in terms of major complication occurred, first passage of stool and length of hospital stay between the two groups. Time of surgery was significantly shorter in LL group compared to IMA preserving group and intra operative blood loss was significantly lower in the LL group. There were no differences in the genito urinary function between the two group pre operatively, at 1 and 9 months post operatively. Genito urinary function did not significantly change across surgery in each groups. The low ligation and the IMA preserving vascular approach are safe end feasible techniques in elective laparoscopic sigmoidectomy for diverticular disease. They both prevent from genito-urinary post-operative disfunction and allow good post operative quality of life. The low ligation approach is related to shorter operative time and slower intra operative blood loss. Celsius.

Managing the urinary tract in spinal cord injury

2010-01-01

This review sets out to provide an overview of the author’s approach to the management of the urinary tract in the patient who has suffered from an injury to their spinal cord. Emphasis is given to the need to understand the fundamental pathophysiological patterns that are seen with injuries that involve the sacral segments of the cord (the conus) and those that spare the conus but interrupt communication between the sacral parasympathetic and somatic centers and the brain (supraconal lesions). The importance of patient participation in management decisions is highlighted by considering the different ways in which the urinary tract can be managed and how the clinician needs to try to meet patient expectations and requirements while establishing safe urological management. Finally, consideration is given to the importance of establishing an appropriate follow up regime and managing urinary tract complications effectively. PMID:20877604

Acute infection of the urinary tract is one of the most commonly encountered bacterial infections in the frail elderly population and is responsible for substantial morbidity and recurrent infections with antibiotic resistance. Although generally considered to be self-limiting without treatment or easily treated with a short antibiotic regime, urinary tract infections (UTIs) often have a dramatic history, associated with incomplete resolution and frequent recurrence. The biological complexity of the infections combined with a dramatic rise in antibiotic-resistant pathogens highlight the need for an anticipating strategy for therapy necessary for a rapid recovery. The first crucial step is the classification in asymptomatic bacteriuria or complicated pyelonephritis, on which the decision for the intensity of treatment and diagnostic effort is based. For the selection of empiric antibiotic therapy, knowledge about the predominant uropathogens as well as local resistance patterns is important. In this manner, most urinary tract infections in the elderly can be treated without greater expense.

Sacral Herpes Zoster Associated with Voiding Dysfunction in a Young Patient with Scrub Typhus.

2015-06-01

When a patient presents with acute voiding dysfunction without a typical skin rash, it may be difficult to make a diagnosis of herpes zoster. Here, we present a case of scrub typhus in a 25-year-old man with the complication of urinary dysfunction. The patient complained of loss of urinary voiding sensation and constipation. After eight days, he had typical herpes zoster eruptions on the sacral dermatomes and hypalgesia of the S1-S5 dermatomes. No cases of dual infection with varicella zoster virus and Orientia tsutsugamushi were found in the literature. In the described case, scrub typhus probably induced sufficient stress to reactivate the varicella zoster virus. Early recognition of this problem is imperative for prompt and appropriate management, as misdiagnosis can lead to long-term urinary dysfunction. It is important that a diagnosis of herpes zoster be considered, especially in patients with sudden onset urinary retention.

Update on voiding dysfunction managed with suprapubic catheterization

PubMed Central

2017-01-01

As the population ages the prevalence of long-term urinary catheters, especially in the elderly, is going to increase. Urinary catheters are usually placed to manage urinary retention or incontinence that cannot be managed any other way. There is significant morbidity associated with an indwelling catheter. The commonest problems are catheter blockages, infection and bladder stones. These will occur with a similar incidence with either a suprapubic or a urethral catheter. Urethral complications such as strictures, scrotal infection and erosion are less common with suprapubic catheterization (SPC). However the benefit of having a SPC needs to be balanced against the risks involved in inserting the catheter suprapubically. Patient reported symptoms show that a SPC is more comfortable and better tolerated than a urethral catheter. However there needs to be more research into developing better catheters that reduce the frequency of urinary infections and blockages and hence catheter morbidity. PMID:28791237

Antimicrobial resistance of pathogens causing urinary tract infection (UTI) is a growing problem, which complicates their effective treatment. Surveillance is needed to guide appropriate empiric therapy. to describe the susceptibility patterns of Gram-negative bacteria isolated of patients with UTI to twelve antibiotics as part of the Study for Monitoring Antimicrobial Resistance Trends in Venezuela. Between 2009-2012 a total of 472 Gram-negative bacteria were isolated from hospitalized patients with UTI. The isolates were sent to Central Laboratory (Central Laboratory of International Health Management Associates) to confirm their identification, and to make susceptibility testing as recommended by the Clinical and Laboratory Standards Institute. Enterobacteriacea comprised 96.6% of the total, where Escherichia coli (76.9%) and Klebsiella pneumoniae (10.6%) were the most frequent. Extended-spectrum β-lactamases (ESBL) was detected in 21.6% of isolates. Top antimicrobial activity were ertapenem, imipenem, and amikacin (> 90.0%), slightly lower for amikacin (85.1%) in ESBL-producing strains. Resistance rates to fluoroquinolones and ampicillin/sulbactam were high (40 y 64%, respectively). These data suggest a necessary revision of the therapeutic regimens for the empirical treatment of UTI in Venezuela.

Complicated urinary tract infections: practical solutions for the treatment of multiresistant Gram-negative bacteria.

Pallett, Ann; Hand, Kieran

Resistance in Gram-negative bacteria has been increasing, particularly over the last 6 years. This is mainly due to the spread of strains producing extended-spectrum β-lactamases (ESBLs) such as CTX-M enzymes or AmpC β-lactamases. Many of the isolates producing these enzymes are also resistant to trimethoprim, quinolones and aminoglycosides, often due to plasmid co-expression of other resistance mechanisms. CTX-M-producing Escherichia coli often occurs in the community and as E. coli is one of the commonest organisms causing urinary tract infections (UTIs) the choice of agents to treat these infections is diminishing. Novel combinations of antibiotics are being used in the community and broad-spectrum agents such as carbapenems are being used increasingly as empirical treatment for severe infections. Of particular concern therefore are reports in the UK of organisms that produce carbapenemases. As resistance is becoming more widespread, prudent use of antimicrobials is imperative and, as asymptomatic bacteriuria is typically benign in the elderly, antibiotics should not be prescribed without clinical signs of UTI. The use of antibiotics as suppressive therapy or long-term prophylaxis may no longer be defensible.

Untreated urinary tract infection (UTI) in pregnancy would cause serious complications for the mother and fetus. The purpose of this study was to assess the associated risk factors of UTI in pregnancy to prevent and control this health problem. Clean-catch midstream urine specimens were collected from 36 pregnant women using sterile containers and were being cultured using standard microbiology test. Patients’ data collected by questionnaire and analyzed using SPSS version 21. The incidence of UTI is 38.9%, Escherichia coli (35.7%) was the commonest bacterial isolate, followed by Staphylococcus aureus (28.6%), Staphylococcus epidermidis (28.6%), and Klebsiella pneumonia (7.1%). Bivariate analysis of associated risk factors of UTI revealed that maternal age group 26-30 years (p = 0.005, PR = 4.098, 95% CI = 1.369, 12.264), gestational age in second trimester (p = 0.009, PR = 4.286, 95% CI = 1.120, 16.405), and sexual activity at least once in the past two weeks (p = 0.012, PR = 3.125, 95% CI = 1.202, 8.122) showed statistical significant association with UTI. On the contrary, there was no significant association among educational level, socioeconomic level, and parity with UTI during pregnancy.

Unfortunately, there is no general consensus as to how long patients with bacteriuria or urinary tract infections should be monitored and certainly there is no agreement on how long recurrent episodes should be treated beyond ten days to two weeks. The most important points to remember are: 1. Culture the urine both at the time of therapy and during follow-up. The patient should be examined periodically for the presence of bacteruria. If bacteria cannot be eradicated, at least the physician is aware of the organism most likely causing the patient's symptoms. 2. Do not subject the patient with frequent recurrent (chronic) and complicated infections to continual antibacterial therapy, but rather, manage the acute episodes. 3. Use prophylaxis, particularly single bed-time doses for dysuria and frequency symptoms. 4. Screen for bacteriuria during pregnancy. 5. Avoid the use of catheters except where absolutely necessary. 6. Avoid systemic prophylaxis of infection in patients with catheters; rather, use closed-system drainage with antibacteri-irrigation. It is to be hoped within the next few years, studies now underway will allow specific recommendations regarding the management of asymptomatic bacteruria, the duration of therapy for recurrent infections, the prevention and treatment of L-form bacterial infections, and indications for urologic procedures.

Pediatric urolithiasis is relatively uncommon and limited information is available on the application of minimally invasive management modalities in young children. We present a single centre experience with extracorporeal shockwave lithotripsy (ESWL) for infants with upper urinary tract calculi. A total of 74 infants aged 3 months to 24 months with upper urinary tract calculi were treated with ESWL under general anesthesia using the Wolf 2500 and the 2501 Piezolith lithotriptors over a 14 and a half-year period. Patient and stone characteristics, risk factors for urolithiasis, treatment parameters, clinical outcomes and long-term follow-up were assessed and recorded. The mean patient age was 14.5 (range 3 to 24) months. The mean renal stone size was 18.2 (range 7 to 32) mm while the mean ureteral stone size was 9.4 (range 5 to 14) mm. Metabolic abnormalities, structural anomalies and urinary tract infections were identified as contributory factors for stone formation in 34% of the infants. At the 3-month follow-up there was an overall successful outcome in 72 infants (97%) that included 65 (88%) who were rendered stone-free and 7 (9%) who had clinically insignificant stone fragments. Retreatment was required in 27 (35%) patients, auxiliary procedures after ESWL were needed in 5 (7%) and secondary operative procedures were required in 2 (3%). Major complications were encountered in 5 (7%) patients that included complete ureteral obstruction with sepsis in 2, partial ureteral obstruction in 1 and febrile urinary tract infection in 2 other children. Long-term follow-up was recorded in 39 infants: 8 developed recurrent stones, 2 had stone regrowth and 1 developed mild hypertension but none had significant deterioration of renal function. ESWL is an effective treatment for upper urinary tract calculi in infants. In the short-term, complications are minimal but long-term follow-up is important.

We aimed to compare outcomes of open and robot-assisted artificial urinary sphincter (AUS) implantation in female patients. The charts of all female patients who underwent an AUS implantation between 2008 and 2014 in a single center were retrospectively reviewed. From 2008 to 2012, AUS were implanted using an open approach and from 2013 to 2014 using a robot-assisted approach. Perioperative and functional parameters were compared between groups. The primary endpoint was continence status. Twenty-four women were assessed: 16 in the open group and eight in the robot-assisted group. Three patients had neurogenic stress urinary incontinence. Most patients had undergone previous procedures for urinary incontinence (15 in the open group and seven in the robotic group). Mean operative time was similar in both groups (214 vs. 211 min; p = 0.90). Postoperative complicationsrate was lower in the robot-assisted group (25 vs. 75 %; p = 0.02). There was a trend toward a lower intraoperative complication rate (37.5 vs. 62.5 %; p = 0.25), decreased blood loss (17 ml vs. 275 ml; p = 0.22), and shorter length of stay (3.5 vs. 9.3 days; p = 0.09) in the robot-assisted group. Continence rates were comparable in both groups (75 vs. 68.8 %; p = 0.75). Three AUS explantations were needed in the open group (18.8 %) compared with one in the robot-assisted group (12.5 %; p = 0.70). In female patients, the robot-assisted approach compared with open AUS implantation could decrease intraoperative and postoperative complication rates, length of hospital stay, and blood loss.

Pathogenesis of dysplastic kidney associated with urinary tract obstruction in utero.

PubMed

Nagata, Michio; Shibata, Sawako; Shu, Yujin

2002-01-01

Renal dysplasia is the major cause of chronic renal failure in children, and is commonly associated with urinary tract obstruction. There are two phenotypes of renal dysplasia associated with urinary tract abnormality, multicystic dysplastic kidney (MCDK) and obstructive dysplasia (ORD). Previous observations by Potter and co-workers suggested that cystic dilatation of the ureteric bud ampula was the cause of renal dysplasia. In this context, our recent investigation of human fetal dysplastic kidneys provided an alternative explanation for the evolution of renal dysplasia. We suggested that in utero urinary tract obstruction may cause urine retention in functioning nephrons and lead to glomerular cysts in the nephrogenic zone. The mechanism was common to MCDK and ORD, albeit at different sites of obstruction. Expansion of glomerular cysts with tubular dilatation (cysts) disturbs the subsequent nephron induction and may contribute to the abnormal development of fetal kidneys.

This study compared outcomes of transurethral enucleation with bipolar (TUEB) with transurethral resection in saline (TURis). Thirty patients who underwent TURis were compared with 30 who underwent TUEB. Perioperative treatment outcomes, preoperative and 1-month postoperative International Prostrate Symptom Scores (IPSS), quality of life (QOL) index, maximum flow rate, average urinary flow, post- void residual urinary volume, and complications were compared. There were no significant differences in IPSS, measurements of urinary flow, or duration of catheterization. However, the improvement of QOL index after surgery was significantly greater in the TUEB group than the TURis group. The TUEB group had significantly longer surgical time, but tended to have greater enucleated tissue weight than the TURis group. There was no significant difference in enucleated tissue weight per unit time between the groups. The TUEB group also tended to have less hemoglobin decrease at postoperative day 1; this tendency was more prominent in patients with an estimated prostate volume of ≥ 50 ml. No significant differences in postoperative complications were observed. This study confirmed that the previously reported safety and efficacy of TUEB are comparable to those of TURis. TUEB appears especially safe for those with a large benign hypertrophic prostate.

Indwelling double J ureteral stents are used for internal urinary diversion for ureteral obstruction and post-surgical drainage of the upper urinary tract. Stent calcification is a serious complication especially in those with forgotten stents. In a retrospective review of 16 patients (10 male and 6 female) we found holmium laser to be highly effective in the management of calcified stents. Encrustations/calcifications were noted on the distal end of the sent in 6 patiens (37.5%), middle and distal portions in 2 patients (12.5%), along the entire length of the stent in 3 patients (18.75%), lower portion of the stent in 4 patients (25%) and at the upper and lower ends of the stent in one patient (6.25%). Cystolitholapaxy, retrograde ureteroscopy (URS) with holmium: YAG (yttrium-aluminum-garnet) laser intracorporeal lithotripsy, percutaneous nephrostolithotomy (PNL) and antegrade URS with holmium: YAG laser intracorporeal lithotripsy were effectively performed without intraoperative complications. Lithotripsy became necessary before stent removal in 11 patients (68.75%). Holmium laser lithotripsy was useful in managing 7 patients (43.75%), and shockwave lithotripsy (SWL) in 6 patients (37.5%). In two patients (12.5%) both holmium and SWL were used before the stent can be removed.

OBJECTIVE ; To review the long-term results of sacral nerve stimulation in the treatment of women with Fowler's syndrome, over a 6-year period at one tertiary referral centre. Between 1996 and 2002, 26 women with urinary retention were treated by implanting a sacral nerve stimulator. Their case records were reviewed for follow-up, complications and revision procedures, and the most recent uroflowmetry results. There were 20 patients (77%) still voiding spontaneously at the time of review (with two having deactivated their stimulator because of pregnancy). Fourteen patients (54%) required revision surgery, and the most common complications included loss of efficacy, implant-related discomfort and leg pain. The mean postvoid residual volume was 75 mL and mean maximum flow rate 20.8 mL/s. In young women with retention, for whom there is still no alternative to lifelong self-catheterization, sacral neuromodulation is effective for up to 5 years after implantation. However, there was a significant complication rate, in line with other reports, which may be improved by new technical developments.

The originally described outside-in procedure for the trans-obturator route was later turned inside-out. We wanted to demonstrate the safety of the two techniques through personal and published experience. Non-randomized, prospective, observational, open-label, longitudinal study of 100 female patients (50 TVT-O and 50 Monarc). All the female patients presented with isolated stress urinary incontinence. Only 4 patients presented with mixed incontinence in the Monarc (MON) group. Sphincter incompetence was observed 4 times in the MON group and 3 times in the TVT-O group. All the patients underwent surgery under assisted local anesthesia in a day-hospital setting. Only those patients presenting with patent established urinary incontinence, corrected by the TVT test, underwent surgery. Post-operative control was conducted at 3 months and 1 year. The duration of hospitalization was 10 h for 48 patients in the MON group and 49 in the TVTO group. The only per-operative complication was a vaginal perforation in the lateral angle of the vagina for a MON patient. Early post-operative complications were observed in the MON group: 3 cases of urinary tract infection, 1 of transient urine retention, 3 of pain in the thighs spontaneously resolving within 4 days and 1 of permanent pain in one leg at time 1 year, which remained bearable. For the TVTO group the post-operative complications consisted in: 1 case of urinary tract infection, 1 of transient retention and 4 of pain in the thigh. No hematoma was reported in either group. Among the late complications, the de novo symptoms included 1 case of imperious urges to urinate in the TVTO group and objective dysuria in 2 cases in the MON group vs. 7 in the TVTO group. There was no statistically significant between-group difference in the complications. No tape exposure was observed. Overall, the recovery rate was 90% at 1 year for MON vs. 94% for TVTO (p = NS) with 2 cases of recurrence between 3 months and 1 year in that series. Mixed incontinence was corrected at time point 1 year in 75% of cases for MON, with 1 case of recurrence in the year. For the patients presenting with sphincter incompetence, competence was maintained at 3 months and 1 year in all cases in the MON group. The 3 TVT-O were cured at 3 months, but 2 recurrences were observed at 1 year. All patients, except one, were satisfied at time point 1 year and those who had sexual relations (54%) did not report any disorder at time point 1 year. The cadaveric studies by advocates of the outside-in technique show a vascular and nervous risk which has received little attention in terms of complications in the literature. Post-operative leg pain is encountered with both techniques and usually is transient. Our experience, like that reported in the literature, shows that the two trans-obturator access routes are equally safe. The clinical results would appear to be equivalent, in terms of recovery, to the rates obtained with retropubic TVT.

Urinary retention following inguinal hernia surgery is common and is believed to be associated with adrenergic over-stimulation of the smooth muscle in the bladder neck and prostate. The efficacy of prophylactic alpha-blockade in the prevention of urinary retention following elective inguinal hernia repair in males is unknown. A comprehensive literature search was performed adhering to PRISMA guidelines. Each study was reviewed and data were extracted. Random-effects models were used to combine data. Five randomized studies describing 456 patients were identified. General or spinal anaesthetic were used. Prophylactic alpha-blockade decreases the risk of urinary retention requiring catheterisation following elective unilateral inguinal hernia repair compared to control groups (OR:0.179, 95% CI:0.043-0.747, p:0.018). Rates of urinary retention between treatment and control groups are reduced by 20.6%. No serious complications relating to alpha blockade occurred. Prophylactic alpha-blockade reduces urinary retention following elective inguinal hernia surgery under general or spinal anaesthetic. Urinary retention is common following inguinal hernia surgery. It is believed to be associated with adrenergic over-stimulation of the smooth muscle in the bladder neck and prostate. Prophylactic alpha-blockade reduces the rates of urinary retention by 20.6% in adult males undergoing general or spinal anaesthetic with minimal associated side effects. Copyright © 2017.

Virulence factors in Proteus bacteria from biofilm communities of catheter-associated urinary tract infections.

2012-07-01

More than 40% of nosocomial infections are those of the urinary tract, most of these occurring in catheterized patients. Bacterial colonization of the urinary tract and catheters results not only in infection, but also various complications, such as blockage of catheters with crystalline deposits of bacterial origin, generation of gravels and pyelonephritis. The diversity of the biofilm microbial community increases with duration of catheter emplacement. One of the most important pathogens in this regard is Proteus mirabilis. The aims of this study were to identify and assess particular virulence factors present in catheter-associated urinary tract infection (CAUTI) isolates, their correlation and linkages: three types of motility (swarming, swimming and twitching), the ability to swarm over urinary catheters, biofilm production in two types of media, urease production and adherence of bacterial cells to various types of urinary tract catheters. We examined 102 CAUTI isolates and 50 isolates taken from stool samples of healthy people. Among the microorganisms isolated from urinary catheters, significant differences were found in biofilm-forming ability and the swarming motility. In comparison with the control group, the microorganisms isolated from urinary catheters showed a wider spectrum of virulence factors. The virulence factors (twitching motility, swimming motility, swarming over various types of catheters and biofilm formation) were also more intensively expressed. © 2012 Federation of European Microbiological Societies.

Urolithiasis is a frequent complication in a heterotopic reservoir and the surgical management could be a difficult problem. Open surgery is not recommended in patients with multiple previous surgeries. A less invasive technique, such as the endourologic procedures, would allow high stone-free rate and low surgical morbidity. Stone formation in the reservoir is a well-known complication of urinary diversion. The incidence of lithiasis in patients with continent urinary diversion is reported as 12-52.5%. Most patients will have multiple physical factors, such as immobility, need for self-catheterization and poor urine drainage, so that it is not certain that an intestinal reservoir is the cause of stones on its own. The management of urolithiasis in continent urinary diversion can be challenging and could be a difficult problem to solve. A less invasive technique, such as the endourologic procedures, is desiderable, especially in patients with kidney transplant and low immune defence. We present the case of a 59-year-old woman with previous history of spina bifida and with neurogenic bladder. At a pediatric age, she underwent incontinent urinary diversion using a sigmo-colic conduit. For several years she had been suffering from kidney stones and recurrent urinary infections, which led to a left nephrectomy for pyonephrosis, subsequent deterioration of renal function and dialysis. In 2004, we performed an atypical continent and self-catheterizable reservoir using the previous colic conduit detubularized and ileum-cecal tract with Mitrofanoff system conduit of 14 Fr size. Finally, kidney transplant was carried out as last surgical procedure. Recently she has come to our attention for multiple and large reservoir stones. preliminary exploration of the continent pouch with flexible cystoscope. Percutaneous access with Endovision° direct control through the afferent conduit with 8 Fr flexible ureteroscope. Dilation of percutaneous tract with pneumatic balloon and positioning 30 Fr Amplats sheet. Lithotripsy, with ultrasound and ballistic sources, was performed and the residual fragments were removed with grasping. At the end of the procedure, after controlling the complete clearance with flexible nephroscope and X-ray, a percutanous 12 Fr catheter and a 12 Fr Foley in the Mitrofanoff conduit were inserted. No fever or increase serum creatinine were observed in the post-operative time. On day 3, we removed the percutaneous foley and after 7 days we performed a cystography with a normal pouch configuration; no leakage or residual fragments were observed. The woman was discarge and returned to usual self-catheterization. The first 3-month post-operative control was regular; no infections or pain were reported. In special cases, like this one, the percutaneous procedure is preferred to open surgery for a best control of the pouch and a simple complete clearence of the fragments.

Hyperammonemia usually results from an inborn error of metabolism or from an advanced liver disease. Individual case reports suggest that both distal renal tubular acidosis and urinary tract infection may also result in hyperammonemia. A systematic review of the literature on hyperammonemia secondary to distal renal tubular acidosis and urinary tract infection was conducted. We identified 39 reports on distal renal tubular acidosis or urinary tract infections in association with hyperammonemia published between 1980 and 2017. Hyperammonemia was detected in 13 children with distal renal tubular acidosis and in one adult patient with distal renal tubular acidosis secondary to primary hyperparathyroidism. In these patients a negative relationship was observed between circulating ammonia and bicarbonate levels (P < 0.05). In 31 patients (19 children, 12 adults), an acute urinary tract infection was complicated by acute hyperammonemia and symptoms and signs of acute neuronal dysfunction, such as an altered level of consciousness, convulsions and asterixis, often associated with signs of brain edema, such as anorexia and vomiting. Urea-splitting bacteria were isolated in 28 of the 31 cases. The urinary tract was anatomically or functionally abnormal in 30 of these patients. This study reveals that both altered distal renal tubular acidification and urinary tract infection may be associated with relevant hyperammonemia in both children and adults.

Radical hysterectomy is associated with a significant amount of urinary functional complications and a negative impact on quality of life. The aim of this review is to provide a comprehensive overview of the neurological etiology of lower urinary tract dysfunction following radical hysterectomy and to establish an optimal postoperative management strategy. We performed a comprehensive overview using the following terms: "radical hysterectomy" and "urologic diseases etiology" or "urologic disease prevention and control". The reported incidence of lower urinary tract dysfunction after radical hysterectomy varies from 12 to 85%. Several animal and clinical urodynamic studies corroborate the neurologic etiology of the dysfunction. Lower urinary tract dysfunction is a common postoperative finding (70-85%) but spontaneous recovery is to be expected within 6-12 months after surgery. The most frequent long term sequela is stress urinary incontinence (40% of cases) and its management is complex and challenging. Postoperative refractory overactive bladder and bladder underactivity can be treated by neuromodulation of sacral roots and superior hypogastric plexus, respectively. In the absence of good clinical predictors, preoperative urodynamic examinations could have a role in understanding the pathophysiology of the dysfunction before such interventions. The pathophysiology of lower urinary tract dysfunction following radical hysterectomy is multifactorial. Its management is complex and should be multidisciplinary.

Enterovesical fistula are pathological connections between the bladder and pelvic intestinal segments. It consists of a rare complication of neoplastic and inflammatory pelvic disorders, in addition to iatrogenic or traumatic injuries, and correlates with both high morbidity and mortality indexes. Male patient, 61 years old, admitted at the hospital clinics featuring abdominal pain and distension, vomiting and fecal retention. Patient's pathological precedents include high blood pressure, diabetes mellitus, vesical dysfunction and recurrent urinary tract infection on the past three years. Magnetic resonance imaging of abdomen and pelvis revealed enterovesical fistula in association with colon diverticular disease of the sigmoid. Management of choice consisted of partial colectomy with bowel lowering and partial cystectomy with surgical double-J stent insertion. Although consisting of a gastrointestinal primary affection, patients with enterovesical fistula usually search for medical help charging urinary tract features. In this particular case, our patient was admitted with gastrointestinal symptoms, reasoned by diagnostic delay, as the patient had already attended at multiple centers with urinary symptoms. Despite being an unusual affection, recurrent urinary tract infection associated with colon diverticular disease must always be considered at differential diagnosis of recurrent urinary tract infection as it concurs with high morbidity and mortality.

To evaluate continence and complication rates of bulbar single-cuff (SC) and distal bulbar double-cuff (DC) insertion in male patients with severe stress urinary incontinence (SUI) according to whether the men were considered low or high risk for unfavourable artificial urinary sphincter (AUS) outcomes. In all, 180 male patients who underwent AUS implantation between 2009 and 2013 were followed according to institutional standards. Patients with previous pelvic radiation therapy, open bulbar urethral or UI surgery ('high risk') underwent distal bulbar DC (123 patients) insertion, all others ('low risk') had proximal bulbar SC (57) insertion. Primary and secondary endpoints consisted of continence and complication rates. Kaplan-Meier analysis determined explantation-free survival, and Cox regression models assessed risk factors for persistent UI and explantation. The median follow-up was 24 months. Whereas there was no significant difference in pad usage/objective continence after SC vs DC insertion, superior rates of subjective/social continence and less persistent UI were reported by the patients with DC devices (all P ≤ 0.02). Overall, device explantation (erosion, infection or mechanical failure) occurred in 12.8% of patients. While early (<6 weeks) complication rates compared with SC patients were similar (P > 0.05), DC patients had a 5.7-fold higher risk of device explantation during late follow-up (P = 0.02) and significantly shorter explantation-free survival (log-rank, P = 0.003). Distal bulbar DC insertion in patients with a 'high-risk' profile (previous pelvic radiation, urethral surgery) leads to similar objective continence, but higher explantation rates when compared with patients considered 'low risk' with proximal bulbar SCs. Randomised controlled trials comparing both devices will be needed to determine whether the higher explanations rates are attributable to the DC device or to underlying risk factors. © 2016 The Authors BJU International © 2016 BJU International Published by John Wiley & Sons Ltd.

Ureterocele is a cystic dilation of the distal ureteral segment. The incidence in women ranges from 1/5,000 to 1/12,000. In adults, they are poorly diagnosed and are asymptomatic. Prolapse through the urethra is uncommon, and involves acute urine retention and a reducible vulvar tumour. Woman of 24 years old, two previous caesarean and two abortions. She had incomplete bladder emptying, intermittent voiding, bladder straining and tenesmus, three months before admission. After the voiding effort she presented with acute urine retention with sudden onset of tumour in the vulva. The tumour was manually reduced under regional anaesthesia. A cystoscopy was performed, finding an ischaemic de-roofing of the anterior wall of the ureterocele, causing vesicoureteral reflux grade IV. Surgical correction was performed with Cohen re-implantation and insertion of a double-J catheter. The catheter was removed 30 days later, with a successful post-operative course. Its aetiology is unclear, and most are diagnosed by ultrasound in the prenatal period. The clinical presentation is variable, from urinary tract infection to prolapse. Despite its size, it may cause complications such as ischaemic de-roofing, which if diagnosed soon may be resolved successfully, as with this patient. The results and treatment may be favourable when no renal impact or concomitant anatomical changes are present, as is the case of this patient. Copyright © 2015 Academia Mexicana de Cirugía A.C.

The aim of this study was to evaluate the effects of 2 types of external ureteral stents on the number of urological complications after kidney transplant. Data were retrospectively collected from 366 consecutive transplants performed between January 2013 and January 2015 in our hospital, in which an external ureteral stent was placed during surgery and removed after 9 days. Urological complications were defined as urinary leakage or ureteral stenosis requiring percutaneous nephrostomy placement. A total of 197 patients received a straight stent with 2 larger side holes (type A; 8F "Covidien" tube; Covidien, Dublin, Ireland) and 169 patients received a single J stent with 7 smaller side holes (type B; 7F "Teleflex" single J stent; Teleflex Medical, Athlone, Ireland). We found a significantly higher number of percutaneous nephrostomy placements with type A stents, with 34 (17%) versus 16 (9%) in type B (P = .030). Reason for percutaneous nephrostomy placement, occurrence of stent dysfunction, and need for early removal (< 8 days) were equal in both groups (P = .397), whereas incidence of rejection and urinary tract infection were higher in type B stent group. Patient and graft survival did not differ between the groups. Use of the type B stent was associated with less urological complications compared with the type A stent.

Most urinary tract infections (UTI) are uncomplicated infections occurring in young women. An extensive evaluation is not required in the majority of cases, and they can be safely managed as outpatients with oral antibiotics. Escherichia coli is by far the most common uropathogen, accounting for >80% of all cases. Other major clinical problems associated with UTI include asymptomatic bacteriuria, and patients with complicated UTI. Complicated UTIs are a heterogeneous group associated with conditions that increase the risk of acquiring infection or treatment failure. Distinguishing between complicated and uncomplicated UTI is important, as it influences the initial evaluation, choice, and duration of antimicrobial therapy. Diagnosis is especially challenging in the elderly and in patients with in-dwelling catheters. The increasing prevalence of resistant uropathogens, including extended-spectrum β-lactamases and carbapenemase-producing Enterobacteriaceae, and other multidrug-resistant Gram-negative organisms further compromises treatment of both complicated and uncomplicated UTIs. The aim of these Clinical Guidelines is to provide a set of recommendations for improving the diagnosis and treatment of UTI.

1999-11-01

The prevalence of vesico-ureteric reflux in the general population is unknown, but it is increased in risk groups, such as children with symptomatic urinary tract infection, schoolgirls with asymptomatic bacteriuria, first-degree relatives of patients with reflux and children with prenatal dilatation of their upper urinary tract. Children and adults with pyelonephritic renal scarring are at risk of serious long-term complications, e.g. hypertension and renal failure. Modern paediatric care, with early detection and treatment of urinary tract infections and reflux during childhood and adolescence, may improve long-term prognosis. In the adult patient with established pyelonephritic renal scarring, careful control of hypertension may retard the rate of progression, and angiotensin converting enzyme inhibitors may have renal protective properties.

Urinary tract infections during pregnancy - an updated overview.

PubMed

Szweda, Hanna; Jóźwik, Marcin

Urinary tract infections (UTIs) are the most common type of infection during pregnancy, affecting up to 10% of pregnant women. They are also recognized as the second most common ailment of pregnancy, after anemia. Three clinical types of pregnancy-related UTI are distinguished: asymptomatic bacteriuria (ASB), cystitis, and pyelonephritis. A particular form of ASB is the presence of Group B streptococci in the urinary tract of the pregnant woman. All clinical types of UTI may lead to serious maternal and fetal complications. Therefore, unlike in the nonpregnant female patient, all UTIs during pregnancy, including the asymptomatic infection, require treatment. In some patients, antibiotic prophylaxis should also be introduced. In the present work, we collectively summarize current practical recommendations from a number of international bodies and organizations.

2013-06-01

Malakoplakia is an unusual and very rare chronic inflammatory disease. In bladder especially it can mimic malignancy and lead to serious misdiagnosis. We presented a case of a middle-aged woman with persistent macrohematuria and cystoscopically polypoid bladder mass that resembled a neoplastic process. The final diagnosis was based on cystoscopic biopsy and microscopic findings of acidophilic, foamy histiocytes with the presence of Michaelis-Gutmann inclusions which are characteristic for diagnosis of malakoplakia. Immunohistochemistry confirmed diagnosis by demonstrating CD68-positive macrophages. Urinary bladder malakoplakia should be considered in patients with persistent urinary tract infections and tumor mass at cystoscopy. Early identification with prompt antibiotic treatment can be helpful in avoiding unnecessary surgical interventions and in preventing development of possible complications.

Urinary tract infections (UTIs) are infectious diseases that commonly occur in communities. Although several international guidelines for the management of UTIs have been available, clinical characteristics, etiology and antimicrobial susceptibility patterns may differ from country to country. This work represents an update of the 2011 Korean guideline for UTIs. The current guideline was developed by the update and adaptation method. This clinical practice guideline provides recommendations for the diagnosis and management of UTIs, including asymptomatic bacteriuria, acute uncomplicated cystitis, acute uncomplicated pyelonephritis, complicated pyelonephritis related to urinary tract obstruction, and acute bacterial prostatitis. This guideline targets community-acquired UTIs occurring among adult patients. Healthcare-associated UTIs, catheter-associated UTIs, and infections in immunocompromised patients were not included in this guideline. PMID:29637759

Nicotine, the main pharmacologically active component in tobacco and cigarette, has some toxic effects and also high potential for addiction. In this study, the effect of artichoke (Cynara scolymus L.) and zeolite nano-materials on urinary excretion of nicotine and consequently elimination of systematically absorbed nicotine was investigated. A simple, valid and highly sensitive high performance liquid chromatography method has been developed for determination of nicotine in rat urine according to guidelines for bioanalysis.It was found that nano-zeolites can cause increase in urinary concentration of nicotine due to its high surface adsorption. Artichoke leaf extract can cause increase in urinary excretion of nicotine in longer post administration times. It was observed that co-administration of nanozeolites and the leaf extract has the synergetic effect on increasing the urinary excretion of nicotine. © Georg Thieme Verlag KG Stuttgart · New York.

A review of post-stroke urinary incontinence.

Cerebrovascular accidents, or strokes, are a common cause of morbidity and mortality in the United States. Urinary incontinence is a prevalent morbidity experienced by post-stroke patients that is associated with long term disability and institutionalization effects on these patients. An extensive literature review was conducted using multiple academic search engines using the keywords: 'stroke,' 'CVA,' 'urinary incontinence,' 'urodynamics,' 'pharmacologic treatments,' and 'conservative treatments.' Articles were reviewed and summarized to explain incidence, assessment, and treatments of urinary incontinence in post-stroke individuals. Twenty-eight percent to seventy-nine percent of stroke survivors experience urinary incontinence with detrusor overactivity being the most common type of incontinence assessed by urodynamic studies. There continues to be insufficient data studying the effects and benefits of non-pharmacologic and pharmacologic treatments in post-stroke patients. Similarly, urinary incontinence remains an indicator of increased morbidity, disability, and institutionalization rates in the post-stroke patient. Stroke is a debilitating disease which causes urinary incontinence in many patients. As a result, patients have increased rates of hospitalization and disability compared to post-stroke patients without urinary incontinence. The history and physical exam are key in diagnosing the type of urinary incontinence with urodynamic studies being an adjunctive study. Non-pharmacologic treatment, such as behavioral therapy, and pharmacologic agents including antimuscarinics and beta adrenergic medications, are not well studied in the post-stroke patient. Urinary incontinence in stroke patients needs to be further studied to help decrease morbidity and mortality rates within this population.

Postoperative Anticholinergic Poisoning: Concealed Complications of a Commonly Used Medication.

PubMed

Zhang, Xiao Chi; Farrell, Natalija; Haronian, Thomas; Hack, Jason

2017-10-01

Scopolamine is a potent anticholinergic compound used commonly for the prevention of postoperative nausea and vomiting. Scopolamine can cause atypical anticholinergic syndromes due to its prominent central antimuscarinic effects. A 47-year-old female presented to the emergency department (ED) 20 h after hospital discharge for a right-knee meniscectomy, with altered mental status (AMS) and dystonic extremity movements that began 12 h after her procedure. Her vital signs were normal and physical examination revealed mydriasis, visual hallucinations, hyperreflexia, and dystonic movements. Laboratory data, lumbar puncture, and computed tomography were unrevealing. The sustained AMS prompted a re-evaluation that revealed urinary overflow with 500 mL of retained urine discovered on ultrasound and a scopolamine patch hidden behind her ear. Her mental status improved shortly after patch removal and physostigmine, with complete resolution after 24 h with discharge diagnosis of scopolamine-induced anticholinergic toxicity. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: Although therapeutically dosed scopolamine transdermal patches rarely cause complications, incomplete toxidromes can be insidiously common in polypharmacy settings. Providers should thoroughly evaluate the skin of intoxicated patients for additional adherent medications that may result in a delay in ED diagnosis and curative therapies. Our case, as well as rare case reports of therapeutic scopolamine-induced anticholinergic toxicity, demonstrates that peripheral anticholinergic effects, such as tachycardia, dry mucous membranes, and hyperpyrexia are often not present, and incremental doses of physostigmine may be required to reverse scopolamine's long duration of action. This further complicates identification of the anticholinergic toxidrome and diagnosis. Published by Elsevier Inc.

Mortality from radical cystectomy is still high, in some series accounting for 1-10% deaths. Morbidity is even higher and can reach 50%. This paper contributes the case of a 66-year old male patient diagnosed with an infiltrant tumour of the bladder following TUR. The patient's background included prior surgery for gastroduodenal ulcus, alcohol consumption, and obesity. Following routine pre-operatory investigations, the patient underwent radical cystectomy using routine techniques and urinary by-pass via transcolonic ureterosigmoidostomy. Increased transaminases, leucocytosis, vomiting, jaundice and extended intestinal ileum were noted during the patient's post-operative period, while blood and urine amylase concentrations were moderately high. Following CAT study, laparotomy was performed and the diagnosed confirmed. The patient died on day 14 of surgery due to secondary pulmonary complications. Post-operative pancreatitis is a low-frequency, high-mortality acknowledged complication. Even though most cases are secondary to biliarypancreatic and surrounding pancreas area surgery, it has also been described in some instances of distant surgery such as the present case. Alcohol consumption, biliary lithiasis, prior cholecystectomy and diabetes are predisposing factors. High amylase values do not always accompany this condition. Early diagnosis and treatment are crucial for the patient's prognosis. Respiratory complications are the usual cause of death in these patients.

Cystinuria.

PubMed

Milliner, D S

1990-12-01

Cystinuria is an hereditary disorder of renal and intestinal transport characterized by the excessive urinary excretion of cystine, arginine, lysine, and ornithine. It is inherited as a common recessive gene with allelic mutations. Complementary studies of the plasma response to oral cystine loading, intestinal mucosal transport patterns, and urine cystine excretion allow separation of homozygous cystinuric subjects into three groups. In type I, the most common form, there is no active transport of cystine or dibasic amino acids across the mucosal gradient, and heterozygous subjects show normal urine cystine values. Type II is characterized by markedly reduced or absent intestinal transport of cystine. Heterozygotes for type II show significantly elevated urine cystine but less than is seen in homozygotes. In type III there is diminished, although demonstrable, intestinal absorption of cystine and dibasic amino acids. Urine cystine in heterozygotes is intermediate between types I and II. Urolithiasis with its attendant complications is the sole clinical manifestation of cystinuria and is due to the relative insolubility of cystine in the urine. The urolithiasis may become clinically manifest at any time from infancy through the ninth decade, although the mean age is the second to third decade. Clinical presentation is similar to that of other types of urolithiasis. Although cystinuria accounts for only 1% to 2% of all urolithiasis and 6% to 8% of urolithiasis in pediatric populations, repeated stone formation in affected patients often causes considerable morbidity. Cystine crystals in the urine are diagnostic but show up in only 19% to 26% of homozygous cystinuric patients. Sodium cyanide nitroprusside is a suitable screening test that should identify homozygous stone formers but will not detect all heterozygotes. A positive screening test should be followed by quantitation of urinary amino acids. A homozygous patient can be functionally defined as one who excretes 250 mg or more of cystine/g of creatinine in a 24-hour urine collection. Other causes of excess urinary cystine must be excluded. Medical therapy will be directed toward dissolution of existing calculi and prevention of new stone formation. Increasing urine volume by generous oral fluid intake is beneficial. Dietary sodium restriction has a favorable effect on urinary cystine excretion. Cystine solubility can be improved by urinary alkalinization and where necessary by the administration of thiol chelators, particularly D-penicillamine or mercaptopropionylglycine. Because these chelators have significant adverse effects, they should be reserved for patients who do not respond to a more conservative program. Patients with infected, symptomatic, or obstructing stones require surgical intervention.(ABSTRACT TRUNCATED AT 400 WORDS)

Complicated urinary tract infections (cUTIs) impose a high burden on healthcare systems and are a frequent cause of hospitalisation. The aims of this paper are to estimate the cost per episode of patients hospitalised due to cUTI and to explore the factors associated with cUTI-related healthcare costs in eight countries with high prevalence of multidrug resistance (MDR). This is a multinational observational, retrospective study. The mean cost per episode was computed by multiplying the volume of healthcare use for each patient by the unit cost of each item of care and summing across all components. Costs were measured from the hospital perspective. Patient-level regression analyses were used to identify the factors explaining variation in cUTI-related costs. The study was conducted in 20 hospitals in eight countries with high prevalence of multidrug resistant Gram-negative bacteria (Bulgaria, Greece, Hungary, Israel, Italy, Romania, Spain and Turkey). Data were obtained from 644 episodes of patients hospitalised due to cUTI. The mean cost per case was €5700, with considerable variation between countries (largest value €7740 in Turkey; lowest value €4028 in Israel), mainly due to differences in length of hospital stay. Factors associated with higher costs per patient were: type of admission, infection source, infection severity, the Charlson comorbidity index and presence of MDR. The mean cost per hospitalised case of cUTI was substantial and varied significantly between countries. A better knowledge of the reasons for variations in length of stays could facilitate a better standardised quality of care for patients with cUTI and allow a more efficient allocation of healthcare resources. Urgent admissions, infections due to an indwelling urinary catheterisation, resulting in septic shock or severe sepsis, in patients with comorbidities and presenting MDR were related to a higher cost. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

Urinary cadmium and mortality among inhabitants of a cadmium-polluted area in Japan

DOE Office of Scientific and Technical Information (OSTI.GOV)

Nakagawa, Hideaki; Nishijo, Muneko; Morikawa, Yuko

The influence of cadmium (Cd) body burden on mortality remains controversial. Excess mortality and the dose-response relationship between mortality and urinary cadmium excretion were investigated in this study among environmentally exposed subjects. A 15-year follow-up study was carried out on 3119 inhabitants (1403 men and 1716 women) of the Cd-polluted Kakehashi River basin, whose urinary Cd concentration was examined in a 1981-1982 health impact survey. The mortality risk of high urinary Cd ({>=}10 {mu}g/g Cr) subjects after adjustment for age using Cox's proportional hazard model was higher than that of moderate urinary Cd (<10 {mu}g/g Cr) subjects in both sexes.more » When the subjects were divided into five groups according to the amount of urinary Cd (<3, 3-5, 5-10, 10-20, {>=}20 {mu}g/g Cr), the mortality risk was significantly increased among the subjects with urinary Cd{>=}3 {mu}g/g Cr in proportion to the increases in the amount of urinary Cd concentration after adjustment for age, especially in women. Furthermore, special causes of death among high and moderate urinary Cd were investigated, and mortality risk ratio for heart failure, which is a cause of death often diagnosed in cases with a gradual deterioration culminating in death, was significantly increased in both sexes, compared with the moderate urinary Cd subjects. Also, in women the mortality risk for renal diseases in the high urinary Cd subjects was significantly higher than that in the moderate urinary Cd subjects. These results suggest that a causal association between Cd body burden and mortality exists among inhabitants environmentally exposed to Cd but that no special disease may be induced except renal diseases.« less

The aim of the case report is presentation of unusual and heavy clinical course of pyelonephritis with renal tissue necrosis in a child with urinary tract malformation. Nine month old girl was admitted to hospital in heavy clinical status due to pyelonephritis--urosepsis. It was complicated by acute renal insufficiency. Patient was treated by broad-spectrum antibiotics and parenteral nutrition. She was feverish for 14 days. Computed tomography done in order to exclude abdominal abscess showed massive renal tissue necrosis of on both sides. Antibiotic treatment was successful after 6 weeks. Urological evaluation revealed bilateral vesico-ureteral refluxes grade IV. Scintigraphy showed multiple scars. Patient was treated Deflux injections (twice). We noted 5 urinary tract recurrences despite antibiotic profilaxis. GFR of 75 ml/min/1.73 m2 was estimated at age of 16 m. Immunodeficiency or malignancy as background of clinical course were excluded. The case we describe presents severe clinical course of pyelonephritis due to complex urinary tract malformation that is to be considered despite based on modern publications "sparing" strategies of diagnosis and profilaxis in urinary tract malformations.

Cosmetic laser use has many pros and cons. The worldwide use of laser for body hair removal has led to many medical complications. Unsupervised use of the laser for hair removal in vulva may result in many problems and can merely damage the vulva, although rarely, affecting the body image. This rare and novel case report is a 21 year old virgin who presented with acute urinary retention and cryptomenorrhea due to complete synlabia secondary to unsupervised vulval laser hair removal. The urinary retention was relieved by suprapubic catheterization initially. During examination under anesthesia, the fused labia were separated by a surgical incision with drainage of hematocolpos and then, a Foley's urethral catheter was inserted. She had an uneventful recovery. We report this case to emphasize on the supervised use of laser by trained and qualified personnel for hair removal in vulva to minimize its complications.

Infections are common complications occurring in malnourished childrenas a result of impaired immunity. Urinary tract infections (UTI) have been found to be the commonest cause of fever in normal children in developing countries. However, data regarding UTI among malnourished children is limited because in most of time severe and moderately malnourished children are afebrile despite significant bacteriuria. A total of 402 malnourished underfives were enrolled. Demographic and other clinical characteristics were collected using standardized data collection tool. Urine specimens were cultured and interpreted according to standard operating procedures. Data were analyzed using STATA version 11. Out of 402 malnourished underfives, 229 (56.9 %) were male. The median age in months was 17 (IQR; 12-31). Of 402 malnourished underfives, 83 (20.3 %) had significant bacteriuria of gram negative enteric bacteria. Escherichia coli 35/84 and Klebsiella pneumonia 20/84 were predominant bacteria isolated. More than 37 % of isolates were resistant to third generation cephalosporins with all of them exhibiting extended spectrum beta lactamase (ESBL) phenotype. Rates of resistance to ampicillin, amoxillin/clavulanic acid, gentamicin and ciprofloxacin were 82/84 (98.7 %), 47/55 (85.4 %), 45/84 (57.8 %) and 9/84 (10.8 %) respectively. Decrease in age and increase in lymphocytes count were independent factors on multivariate logistic regression analysis found to predict UTI (p<0.05). Multi-resistant gram negative enteric bacteria are common cause of UTI among underfives. A significant number of severe and moderate malnourished children with bacteriuria had no fever. Therefore, routine testing for UTI is emphasized in all malnourished underfives so that appropriate treatment can be initiated.

Standardized methods of reporting complications after radical cystectomy (RC) and urinary diversions (UD) are necessary to evaluate the morbidity associated with this operation to evaluate the modified Clavien classification system (CCS) in grading perioperative complications of RC and UD in a real life cohort of patients with bladder cancer. A consecutive series of patients treated with RC and UD from April 2011 to March 2012 at 19 centers in Italy was evaluated. Complications were recorded according to the modified CCS. Results were presented as complication rates per grade. Univariate and binary logistic regression analysis were used for statistical analysis. 467 patients were enrolled. Median age was 70 years (range 35-89). UD consisted in orthotopic neobladder in 112 patients, ileal conduit in 217 patients and cutaneous ureterostomy in 138 patients. 415 complications were observed in 302 patients and were classified as Clavien type I (109 patients) or II (220 patients); Clavien type IIIa (45 patients), IIIb (22 patients); IV (11 patients) and V (8 patients). Patients with cutaneous ureterostomy presented a lower rate (8%) of CCS type ≥IIIa (p = 0.03). A longer operative time was an independent risk factor of CCS ≥III (OR: 1.005; CI: 1.002-1.007 per minute; p = 0.0001). In our study, RC is associated with a significant morbidity (65%) and a reduced mortality (1.7%) when compared to previous experiences. The modified CCS represents an easily applicable tool to classify the complications of RC and UD in a more objective and detailed way. Copyright © 2013 Elsevier Ltd. All rights reserved.

Cystectomy combined with pelvic lymph-node dissection and urinary diversion entails high morbidity and mortality. Improvements are needed, and a first step is to collect information on the current situation. In 2011, this group took the initiative to start a population-based database in Sweden (population 9.5 million in 2011) with prospective registration of patients and complications until 90 days after cystectomy. This article reports findings from the first year of registration. Participation was voluntary, and data were reported by local urologists or research nurses. Perioperative parameters and early complications classified according to the modified Clavien system were registered, and selected variables of possible importance for complications were analysed by univariate and multivariate logistic regression. During 2011, 285 (65%) of 435 cystectomies performed in Sweden were registered in the database, the majority reported by the seven academic centres. Median blood loss was 1000 ml, operating time 318 min, and length of hospital stay 15 days. Any complications were registered for 103 patients (36%). Clavien grades 1-2 and 3-5 were noted in 19% and 15%, respectively. Thirty-seven patients (13%) were reoperated on at least once. In logistic regression analysis elevated risk of complications was significantly associated with operating time exceeding 318 min in both univariate and multivariate analysis, and with age 76-89 years only in multivariate analysis. It was feasible to start a national population-based registry of radical cystectomies for bladder cancer. The evaluation of the first year shows an increased risk of complications in patients with longer operating time and higher age. The results agree with some previously published series but should be interpreted with caution considering the relatively low coverage, which is expected to be higher in the future.

Although the epidemiology of catheter-associated urinary tract infection is well-described, little is known about noninfectious complications resulting from urethral catheter use. To determine the frequency of noninfectious complications after catheterization. MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, CINAHL, Conference Papers Index, BIOSIS Previews, Scopus, and ClinicalTrials.gov were searched for human studies without any language limits and through 30 July 2012. Clinical trials and observational studies assessing noninfectious complications of indwelling urethral catheters in adults. Relevant studies were sorted into 3 categories: short-term catheterization in patients without spinal cord injury (SCI), long-term catheterization in patients without SCI, and catheterization in patients with SCI. The proportion of patients who had bladder cancer, bladder stones, blockage, false passage, gross hematuria, accidental removal, urine leakage, or urethral stricture was then pooled using random-effects models. Thirty-seven studies (2868 patients) were pooled. Minor complications were common. For example, the pooled frequency of urine leakage ranged from 10.6% (95% CI, 2.4% to 17.7%) in short-term catheterization cohorts to 52.1% (CI, 28.6% to 69.5%) among outpatients with long-term indwelling catheters. Serious complications were also noted, including urethral strictures, which occurred in 3.4% (CI, 1.0% to 7.0%) of patients with short-term catheterization. For patients with SCI, 13.5% (CI, 3.4% to 21.9%) had gross hematuria and 1.0% (CI, 0.0% to 5.0%) developed bladder cancer. Although heterogeneity existed across studies for several outcomes, most could be accounted for by differences between studies with respect to quality and sex composition. Evidence published after 30 July 2012 is not included. Many noninfectious catheter-associated complications are at least as common as clinically significant urinary tract infections.

Transsphenoidal surgery (TSS) has emerged as the standard approach for pituitary resection due to its minimally invasive nature. There has been little analysis examining the impact of diabetes mellitus (DM) on patients undergoing TSS. In this study, we characterize DM's association with postoperative TSS complications. In addition to analysis of associated charges and patient demographics, we performed comparison of complication rates between DM and non-DM patients who have undergone TSS in recent years. The Nationwide Inpatient Sample, a database encompassing nearly 8 million inpatient hospitalizations, was evaluated for patients undergoing TSS from 2002 to 2010. Of 12,938 TSS patients, 2,173 (16.8%) had a DM diagnosis. The non-DM cohort was younger (50.1 y ± 16.6SD vs. 56.8 y ± 14.1; P < 0.001) and had shorter hospitalizations and lesser charges. DM patients had a greater incidence of pulmonary, cardiac, urinary/renal, and fluid/electrolyte complications, and had a lesser incidence of diabetes insipidus (P < 0.05). Upon controlling for age, the greater incidence of pulmonary and fluid/electrolyte complications was present only among patients < 60 years of age. Higher occurrence of cerebrospinal fluid rhinorrhea was noted among black diabetics when compared to non-DM blacks. DM is associated with greater length of stay and hospital charges among TSS patients. DM patients undergoing TSS have a significantly greater incidence of pulmonary and fluid/electrolyte complications among patients under the age of 60, and greater risk for urinary/renal complications across all ages. Despite a theoretical concern due to an impaired wound-healing in DM patients, association with cerebrospinal fluid rhinorrhea was only noted among black diabetics. 2C. © 2015 The American Laryngological, Rhinological and Otological Society, Inc.

Diabetes mellitus is a vastly prevalent metabolic disorder with escalating global health concerns. Particularly when mismanaged, chronic micro- and macrovascular complications may highly impair physiological systems while immunodeficiency disposes us to infection. We investigate infections, localized complications, and neoplasms of the genitourinary system secondary to the chronic complications of diabetes mellitus in males and females. A comprehensive MEDLINE® search was guided using key words relevant to diabetes mellitus and the genitourinary system. Pathogen-friendly environments may implicate the sequelae of urinary tract and genital mycotic infections, potentially generating necrosis, abscess, and other inflammatory complications, which may present concomitantly with neurogenic and/or vasculogenic dysfunction to further exacerbate an existing genitourinary condition. Manifestations of the adrenal, renal, and genital organs and tissues are discussed as they relate to vascular, immunodeficient, and other hyperglycemic complications of the diabetic state. Among those, chronic kidney disease and cystopathy are the most prevailing and detrimental. Though studies have connected diabetes to either an increased risk of developing or poor prognosis of bladder, renal, prostate, endometrial, and cervical cancers, the explicit biological relationships are as of yet inconclusive. Despite the availability of precise treatments to ameliorate most presently reviewed conditions, particularly urinary tract and genital mycotic infection-related sequelae, reversing permanent vascular damage remains a great challenge. Leading a healthier lifestyle and managing diabetes mellitus with a patient-centric approach from the outset are the most putative methods for preventing critical long-term genitourinary manifestations of diabetes mellitus.

2016-01-01

The clinical syndromes comprising urinary tract infection (UTI) continue to exert significant impact on millions of patients worldwide, most of whom are otherwise healthy women. Antibiotic therapy for acute cystitis does not prevent recurrences, which plague up to one fourth of women after an initial UTI. Rising antimicrobial resistance among uropathogenic bacteria further complicates therapeutic decisions, necessitating new approaches based on fundamental biological investigation. In this review, we highlight contemporary advances in the field of UTI pathogenesis and how these might inform both our clinical perspective and future scientific priorities. PMID:27692880

Leech in urinary bladder causing hematuria.

To estimate efficacy of normal saline in the management of hematuria caused by accidental entry of a leech per urethra into the urinary bladder. An intervention study was carried out in the Department of Pediatric Surgery of Sylhet MAG Osmani Medical College between January 1998 and December 2003. A total of 43 boys (mean age 8 years, SD+/-2.6) were enrolled. In all cases, a leech had entered the urinary bladder through the urethra causing hematuria. All patients were equipped with a self-retaining Foley catheter. They were managed by infusing 50ml of normal saline into the urinary bladder through the catheter that was then clamped for 3h. After removing the catheter, in all cases the whole leech was spontaneously expelled intact, dead or alive, within 2-24h during the subsequent act of micturition. Hematuria gradually diminished to a clear flow within the next 6h in 27 cases, 12h in 14 cases and 24h in two cases. All patients were followed up for 2 weeks, and none developed recurrent hematuria. Catheterization and irrigation of the urinary bladder with normal saline is a relatively simple, safe and inexpensive method of removing the leech and controlling hematuria.

Acute urinary retention in women is rare. The varicella-zoster virus causes inflammatory lesions of the sensory-root ganglions, meninges and, less frequently, spinal cord. Herpes zoster has been reported to affect, although rarely, lower urinary tract innervations, and acute urinary retention can be thought to occur in the presence of sacral dermatome involvement. Usually it is located in S2-4 dermatome and the prognosis for acute urinary retention is benign resolving in about 20 days. We present a case in which the S1 dermatome was involved and acute urinary retention developed. After 10 days of specific therapy and self-catheterization the problem resolved.

Long-term complications following bladder augmentations in patients with spina bifida: bladder calculi, perforation of the augmented bladder and upper tract deterioration

PubMed Central

2016-01-01

Background We desire to review our experience with bladder augmentation in spina bifida patients followed in a transitional and adult urologic practice. This paper will specifically focus on three major complications: bladder calculi, the most frequent complication found following bladder augmentation, perforation of the augmentation, its most lethal complication and finally we will address loss of renal function as a direct result of our surgical reconstructive procedures. Methods We reviewed a prospective data base maintained on patients with spina bifida followed in our transitional and adult urology clinic from 1986 to date. Specific attention was given to patients who had developed bladder calculi, sustained a spontaneous perforation of the augmented bladder or had developed new onset of renal scarring or renal insufficiency (≥ stage 3 renal failure) during prolonged follow-up. Results The development of renal stones (P<0.05) and symptomatic urinary tract infections (P<0.0001) were found to be significantly reduced by the use of high volume (≥240 mL) daily bladder wash outs. Individuals who still developed bladder calculi recalcitrant to high volume wash outs were not benefited by the correction of underlying metabolic abnormalities or mucolytic agents. Spontaneous bladder perforations in the adult patient population with spina bifida were found to be directly correlated to substance abuse and noncompliance with intermittent catheterization, P<0.005. Deterioration of the upper tracts as defined by the new onset of renal scars occurred in 40% (32/80) of the patients managed by a ileocystoplasty and simultaneous bladder neck outlet procedure during a median follow-up interval 14 years (range, 8–45 years). Development of ≥ stage 3 chronic renal failure occurred within 38% (12/32) of the patients with scarring i.e., 15% (12/80) of the total patient population. Prior to the development of the renal scarring, 69% (22/32) of the patients had been noncompliant with intermittent catheterization. The onset of upper tract deterioration (i.e., new scar formation, hydronephrosis, calculus development, decrease in renal function) was silent, that is, clinically asymptomatic in one third (10/32 pts). Conclusions This paper documents the need for high volume bladder irrigations to both prevent the most common complication following bladder augmentation, which is the development of bladder calculi and to reduce the incidence of symptomatic urinary tract infections. It provides a unique perspective regarding the impact of substance abuse and patient non-compliance with medical directives as being both the most common cause for both spontaneous bladder rupture following augmentation cystoplasty and for deterioration of the upper tracts. These findings should cause the surgeon to reflect on his/her assessment of a patient prior to performing a bladder augmentation procedure and stress the need for close follow-up. PMID:26904407

The retropubic tension-free vaginal tape (TVT) procedure replaced Burch colposuspension as the primary surgical method for stress urinary incontinence (SUI) and mixed urinary incontinence (MUI) in women in our department in 1998. In this study we compared the short-term and long-term clinical outcomes of these surgical procedures. Using a case series design, we compared the last 5 years of the Burch procedure (n = 127, 1994-1999) with the first 5 years of the retropubic TVT procedure (n = 180, 1998-2002). Information from the medical records was transferred to a case report form comprising data on perioperative and long-term complications as well as recurrence of UI, defined as bothersome UI or UI in need of repeat surgery. Other endpoints were rates of perioperative and late complications and the rates of prolapse surgery after primary surgery. The data were analyzed with the chi-squared and t tests and survival analysis using SPSS. The cumulative recurrence rate of SUI in women with preoperative SUI was significantly higher after the Burch procedure, but no difference was observed in women with MUI. There were no significant differences in rates of perioperative and late complications. At 12 years there was a significant increase in rates of repeat surgery for incontinence and prolapse in women after the Burch procedure. The long-term efficacy of TVT surgery was superior to that of Burch colposuspension in women with SUI. In addition, the rate of late prolapse surgery was significantly higher after the Burch procedure.

Conservative management in ureteric hydronephrosis due to deep endometriosis: Could the levonorgestrel-intrauterine device be an option?

2017-07-01

Endometriosis can affect up to 10% of women of reproductive age, in a wide range of clinical presentations that vary from mild to severe or deep endometriosis. Deep endometriosis can affect the urinary tract in 1-5% to 15-25% cases. Even though deep endometriosis' surgeries are usually complex with higher rate of complications, conservative management is not always considered as an option because of its high failure rates. This paper describes two cases of deep endometriosis with ureteric involvement (hydronephrosis) treated conservatively with a double-pigtail stent plus a Levonorgestrel intrauterine device, after conservative surgery, who remained symptom free with no evidence of recurrence at 3 years follow-up, avoiding radical high-risk surgery. Impact statement Several treatments have been described for endometriosis. From a symptomatic perspective, conservative medical management has been proposed with a variable response. Concerning deep endometriosis (affecting the urinary or digestive tract), the definitive treatment has always been thought to be radical surgery. However, this can lead to several complications. To illustrate a possible more conservative approach this paper describes two cases of deep infiltrating endometriosis affecting the ureter, treated conservatively with a temporary pigtail ureter stent plus a Levonorgestrel intrauterine device. The management demonstrates that, in a selected population, conservative treatment solves the urinary disease avoiding the surgical complications and, what is more, improving patients' symptoms in a permanent way. Further prospective studies are needed to confirm whether the introduction of this management in clinical practice would reduce the need for surgery thereby, avoiding high-risk surgery and improving the success rate of conservative management.

Objectives: To study retrospectively the frequency, demographic, phenomenological, and psychiatric profile in patients presented with self-insertion of foreign bodies in the lower genitourinary tract in our institute. Materials and Methods: From January 2009 to 2015, the records of patients admitted with self-insertion of foreign bodies into the lower urinary tract were analyzed retrospectively regarding demographic and phenomenological profile, the mode of presentation, diagnosis, management, complications, and possible contributing factors leading to the event. Results: Out of 17,978 inpatients, ten patients (0.055%) presented with foreign body insertion in the lower genitourinary tract in last 6 years. Mean age was 28.1 ± 13.9 (7–50) years. Objects used for insertion were varied from seeds, twigs to the electric wire. The contributing factors were lack of partner, misconception about masturbation, and underlying psychiatric illness. The presenting symptoms were pain and swelling of the penis, difficulty in voiding, and skin ulceration. The diagnosis was possible by simple observation in four patients, X-ray kidney, ureter, and bladder, and sonography of the pelvis in six patients. Five patients had endoscopic retrieval of foreign body, 2 had an open, suprapubic cystotomy, urethrotomy was needed in one patient, and forceps removal in two patients. There were no postoperative complications. Psychiatric profile was evaluated in nine patients. Conclusions: Foreign body insertion to lower urinary tract was rare. A main cause for insertion of foreign bodies was autoerotism, misconceptions regarding masturbation, and underlying psychiatric illness. In addition to suitable method of surgical removal, counseling and psychiatric evaluation are necessary to prevent recurrences or for early detection of psychiatric problems. PMID:27453657

We report herein a 27-year-old male case of inherited distal renal tubular acidosis complicated with renal diabetes insipidus, the symptoms of which were aggravated by the occurrence of diabetes mellitus. At 2 months after birth, he was diagnosed as having inherited distal renal tubular acidosis and thereafter supplementation of both potassium and alkali was started to treat his hypokalemia and metabolic acidosis. At the age of 4 years, calcification of the bilateral renal medulla was detected by computed tomography. Subsequently his urinary volume gradually increased and polyuria of approximately 4 L/day persisted. At the age of 27 years, he became fond of sugar-sweetened drinks and also often forgot to take the medicine. He was admitted to our hospital due to polyuria of more than 10 L day, muscle weakness and gait disturbance. Laboratory tests disclosed worsening of both hypokalemia and metabolic acidosis in addition to severe hyperglycemia. It seemed likely that occurrence of diabetes mellitus and cessation of medications can induce osmotic diuresis and aggravate hypokalemia and metabolic acidosis. Consequently, severe dehydration, hypokalemia-induced damage of his urinary concentration ability and enhancement of the renin angiotensin system occurred and thereby possibly worsened his hypokalemia and metabolic acidosis. As normalization of hyperglycemia and metabolic acidosis might have exacerbated hypokalemia further, dehydration and hypokalemia were treated first. Following intensive treatment, these abnormalities were improved, but polyuria persisted. Elevated plasma antidiuretic hormone (12.0 pg/mL) and deficit of renal responses to antidiuretic hormone suggested that the polyuria was attributable to the preexisting renal diabetes insipidus possibly caused by bilateral renal medulla calcification. Thiazide diuretic or nonsteroidal anti-inflammatory drugs were not effective for the treatment of diabetes insipidus in the present case.

Nucleotide excision repair (NER) is an essential biological pathway protecting against ultraviolet light-induced DNA damage. Deficient NER causes a group of rare genetic disorders including two autosomal recessive diseases, xeroderma pigmentosum (XP) and Cockayne syndrome (CS). In addition to the cutaneous photosensitivity shared in XP and CS, CS is featured by growth failure, neurological deterioration, microcephaly, and deep sunken eyes. XP/CS complex is an extremely rare type of NER disorder with a distinct phenotype that is characterized by the skin and eye pathology of XP and the somatic and neurological abnormalities of CS. Some of CS cases have been reported to be complicated with renal failure, but the genetic background or the etiology of the renal failure has not been reported. We herein report a 1-year-old Japanese boy with XP/CS complex, complicated by nephrotic syndrome. Diagnosis was confirmed by the presence of compound heterozygous mutations, G47R (c.139G>A) and R616G (c.1846C>G), in the excision repair cross-complementation group 2 (ERCC2) gene. The kidney biopsies, performed at the age of 1 year and 2 months, revealed diffuse expansion of the mesangial matrix and segmental glomerulosclerosis under light microscopy, and diffused thin capillary walls with partially lamellated regions under electron microscopy. Notably, high levels of urinary 8-hydroxy-2'-deoxyguanosin, known as an oxidative stress marker, were observed during the clinical course. The patient died at the age of 1 year and 11 months because of renal failure. We suggest the involvement of oxidative stress in the pathogenesis of nephrotic syndrome in NER disorders.

Purpose: Malignancies may cause urinary tract obstruction, which is often relieved with placement of a percutaneous nephrostomy tube, an internal double J nephro-ureteric stent (double J), or an internal external nephroureteral stent (NUS). We evaluated the affect of these palliative interventions on quality of life (QoL) using previously validated surveys. Methods: Forty-six patients with malignancy related ureteral obstruction received nephrostomy tubes (n = 16), double J stents (n = 15), or NUS (n = 15) as determined by a multidisciplinary team. QoL surveys were administered at 7, 30, and 90 days after the palliative procedure to evaluate symptoms and physical,more » social, functional, and emotional well-being. Number of related procedures, fluoroscopy time, and complications were documented. Kruskal-Wallis and Friedman's test were used to compare patients at 7, 30, and 90 days. Spearman's rank correlation coefficient was used to assess correlations between clinical outcomes/symptoms and QoL. Results: Responses to QoL surveys were not significantly different for patients receiving nephrostomies, double J stents, or NUS at 7, 30, or 90 days. At 30 and 90 days there were significantly higher reported urinary symptoms and pain in those receiving double J stents compared with nephrostomies (P = 0.0035 and P = 0.0189, respectively). Significantly greater fluoroscopy time was needed for double J stent-related procedures (P = 0.0054). Nephrostomy tubes were associated with more frequent minor complications requiring additional changes. Conclusion: QoL was not significantly different. However, a greater incidence of pain in those receiving double J stents and more frequent tube changes in those with nephrostomy tubes should be considered when choosing palliative approaches.« less

A primiparous, full-term, 28-year-old woman underwent an emergency lower segment Caesarean section under epidural anaesthesia for failure to progress in the first stage. Despite an uneventful pregnancy and delivery, she developed a hypertensive crisis in the postoperative period complicated by acute pulmonary oedema requiring ventilation for 48 h in the intensive care unit. Intravenous magnesium sulphate infusions and hydralazine boluses were used to control the blood pressure, which was associated with clonus, hyperreflexia, tachycardia and profuse sweating. The patient made a good recovery. Later measurement of urinary catecholamines in the recovery phase showed greatly elevated levels of norepinephrine, dopamine and vanillyl mandelic acid. Further investigations included a normal abdominal computed tomography scan and a I-123 meta-iodo-benzyl-guanidine scintigraphy scan which revealed a 3- to 4-cm irregular tumour located at the level of the lower pole of the right kidney and further liver hot spots. Intravenous magnesium sulphate infusion proved successful in controlling hypertension caused by a phaeochromocytoma in the postpartum period.

[Indications and morbidity associated with double J catheters.

The use of double J catheters is usual in urologist's daily practice. The indication can be divided in prophylactic or therapeutic. Prophylactically, they prevent complications derived from endourological procedures, such as ureteral lesion or obstructive uropathy secondary to residual lithiasis or edema. Therapeutically, they treat obstructive uropathy of many different pathologies, either in an emergency setting or scheduled, such as lithiasis, stenosis, extrinsic compression of any nature or urinary tract tumors among others. Although they add clear benefits in both cases, they are not free from side effects. The most frequent symptoms they cause are: voiding urgency and increase in voiding frequency, macroscopic hematuria and suprapubic and lumbar pain. The physiopathological mechanism is explained by a mechanical and inflammatory effect or due to vesicoureteral reflux depending on the symptom. This causes patient's quality of life disturbance that may vary from mild degree to very severe. Thus, several strategies have emerged with the aim of diminishing or palliate the intensity of such symptoms: alpha-blocker drugs, design modifications or reduction of their use.

To explore operative complications of photoselective vaporization of prostate (120 W) for treatment of benign prostatic hyperplasia (BPH). The clinical data of 186 cases who underwent photoselective vaporization of prostate (120 W) for the treatment of BPH from May 2010 to April 2012, was statistically analyzed. The operative time ranged from 7 to 147 minutes, and the average time was (37.7 ± 21.5) minutes. No patient accepted intraoperative blood transfusion, and occurred transurethral resection syndrome or capsular perforation. The time of postoperative indwelling catheter ranged from 1 to 11 days, and average time was (4.3 ± 2.2) days. Surgical outcome was satisfactory. Early postoperative complications included bladder spasm (3 cases), transient dysuria (19 cases), urinary tractirritation (94 cases), secondary hemorrhage (26 cases), transient urge incontinence (19 cases), all cases were relieved after treatment. Long-term complications, including recurrence (1 case), bladder neck stenosis (2 cases) and urethral stricture (2 cases), who had required reoperation. Postoperative patients with international prostate symptom score (29.4 ± 3.4), maximum urinary flow rate ((6.0 ± 1.6) ml/s) and residual urine ((167 ± 150) ml) had improved (t = -76.0 - 61.4, P < 0.01). With less invasive, less bleeding and rapid postoperative recovery, photoselective vaporization of prostate (120 W) is a safe and effective minimally invasive treatment techniques for BPH. But there is still some complications after surgery and proper handling is required.

AIM: To assess effectiveness, complications, recurrence rate, and recent improvements of the anterior rectopexy procedure for treatment of total rectal prolapse. METHODS: MEDLINE, PubMed, EMBASE, and other relevant database were searched to identify studies. Randomized controlled trials, non-randomized studies and original articles in English language, with more than 10 patients who underwent laparoscopic ventral rectopexy for full-thickness rectal prolapse, with a follow-up over 3 mo were considered for the review. RESULTS: Twelve non-randomized case series studies with 574 patients were included in the review. No surgical mortality was described. Conversion was needed in 17 cases (2.9%), most often due to difficult adhesiolysis. Twenty eight patients (4.8%) presented with major complications. Seven (1.2%) mesh-related complications were reported. Most frequent complications were urinary tract infection and urinary retention. Mean recurrence rate was 4.7% with a median follow-up of 23 mo. Improvement of constipation ranged from 3%-72% of the patients and worsening or new onset occurred in 0%-20%. Incontinence improved in 31%-84% patients who presented fecal incontinence at various stages. Evaluation of functional score was disparate between studies. CONCLUSION: Based on the low long-term recurrence rate and favorable outcome data in terms of low de novo constipation rate, improvement of anal incontinence, and low complications rate, laparoscopic anterior rectopexy seems to emerge as an efficient procedure for the treatment of patients with total rectal prolapse.

National quality programs have been implemented to decrease the burden of adverse events on key outcomes in bariatric surgery. However, it is not well understood which complications have the most impact on patient health. To quantify the impact of specific bariatric surgery complications on key clinical outcomes. The Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database. Data from patients who underwent primary bariatric procedures were retrieved from the MBSAQIP 2015 participant use file. The impact of 8 specific complications (bleeding, venous thromboembolism [VTE], leak, wound infection, pneumonia, urinary tract infection, myocardial infarction, and stroke) on 5 main 30-day outcomes (end-organ dysfunction, reoperation, intensive care unit admission, readmission, and mortality) was estimated using risk-adjusted population attributable fractions. The population attributable fraction is a calculated measure taking into account the prevalence and severity of each complication. The population attributable fractions represents the percentage reduction in a given outcome that would occur if that complication were eliminated. In total, 135,413 patients undergoing sleeve gastrectomy (67%), Roux-en-Y gastric bypass (29%), adjustable gastric banding (3%), and duodenal switch (1%) were included. The most common complications were bleeding (.7%), wound infection (.5%), urinary tract infection (.3%), VTE (.3%), and leak (.2%). Bleeding and leak were the largest contributors to 3 of 5 examined outcomes. VTE had the greatest effect on readmission and mortality. This study quantifies the impact of specific complications on key surgical outcomes after bariatric surgery. Bleeding and leak were the complications with the largest overall effect on end-organ dysfunction, reoperation, and intensive care unit admission after bariatric surgery. Furthermore, our findings suggest that an initiative targeting reduction of post-bariatric surgery VTE has the greatest potential to reduce mortality and readmission rates.

Urinary tract infection caused by Chromobacterium violaceum.

PubMed

Pant, Narayan Dutt; Sharma, Manisha

2015-01-01

Chromobacterium violaceum, a proteobacterium, is a facultative anaerobe, which is generally present as the normal flora of water and soil in tropical and subtropical regions. The infection due to Chromobacterium violaceum is rare but mostly fatal. It is responsible for causing fatal cases of septicemia, visceral abscesses, skin and soft tissue infections, meningitis, diarrhea, and rarely urinary tract infection. The bacteria has high propensity to spread causing sepsis. Delayed proper treatment due to limited awareness related to the C. violaceum infection is responsible for the high mortality rate. Here, we describe a rare case of urinary tract infection by C. violaceum in a chronic kidney disease patient, which was managed with timely proper antimicrobial therapy as per the culture sensitivity report.

Urinary tract infection (UTI) is a common complication of pregnancy. It may be symptomatic or asymptomatic. The aim of this cross sectional study was to identify bacterial agents and their antibiotic susceptibility pattern isolated from pregnant women with UTI attending antenatal clinic of Tikur Anbessa Specialized Hospital (TASH). Four hundred and fourteen pregnant women with asymptomatic UTI (n = 369) and symptomatic UTI (n = 45) were investigated for urinary tract infection from January to March 2005. The age range of both groups was 18 to 44 years. Bacteriological screening of mid-stream urine specimens revealed that 39/369 (10.6%) and 9/45 (20%) had significant bacteriuria in asymptomatic and symptomatic group, respectively (p = 0.10). The overall prevalence of urinary tract infection was 48/414 (11.6%). The bacterial pathogens isolated were predominantly E. coil (44%), followed by S. aureus (20%), coagulase-negative staphylococci (16%), and K. pneumoniae (8%). Others found in small in number included P. mirabilis, P. aeruginosa, Enterococcus spp. and non-Group A-beta hemolytic Streptococcus, this accounted 2% for each. The gram positive and negative bacteria accounted 40% and 60% respectively. The susceptibility pattern for gram-negative bacteria showed that most of the isolates (> 65% of the strains) were sensitive to amoxicillin-clavulanic acid (70%), chloramphenicol (83.3%), gentamicin (93.3%), kanamycin (93.3%), nitrofurantoin (87.7%) and trimethoprim-sulphamethoxazole (73.3%). Among the gram-positives, more than 60% of the isolates were sensitive to amoxicillin-clavulanic acid (100%), cephalothin (95%), chloramphenicol (70%), erythromycin (80%), gentamicin (85%), methicillin (83.3%), nitrofurantoin (100%) and trimethoprim-sulphamethoxazole (65%). Generally, amoxicillin-clavulanic acid, chloramphenicol, gentamicin, nitrofurantoin and trimethoprim-sulphamethoxazole were effective at least in 70% of the isolates. Multiple drug resistance (resistance two or more drugs) was observed in 74% of the isolates. Significant bacteriuria was observed in both asymptomatic and symptomatic pregnant women. Periodic studies are recommended to confirm the findings of this study and also monitor any changes in the susceptibility patterns of uropathogens causing urinary tract infection in the pregnant women.

To describe successful surgical treatment of urinary incontinence caused by a ruptured and/or transected urethral sphincter in a mare. Clinical report. A 7-year-old, Swedish Warmblood mare with urinary incontinence. The urethral sphincter, which had been damaged during removal of a cystic urolith, was repaired by apposing the ends of the disrupted urethralis muscle and tunica muscularis. The mare was no longer incontinent after repair of the defect by apposition of the ends of the urethralis muscle and tunica muscularis. Transection and/or rupture of the urethral sphincter of a mare may result in urinary incontinence. Apposition of the ends of the ruptured or transected urethralis muscle and tunica muscularis can correct urinary incontinence caused by this defect. © Copyright 2010 by The American College of Veterinary Surgeons.

Concentrations of urinary steroids are measured in anti-doping test programs to detect doping with endogenous steroids. These concentrations are combined into ratios and followed over time in the steroidal module of the Athlete Biological Passport (ABP). The most important ratio in the ABP is the testosterone/epitestosterone (T/E) ratio but this ratio is subject to intra-individual variations, especially large in women, which complicates interpretation. In addition, there are other factors affecting T/E. Pregnancy, for example, is known to affect the urinary excretion rate of epitestosterone and hence the T/E ratio. However, the extent of this variation and how pregnancy affect other ratios has not been fully evaluated. Here we have studied the urinary steroid profile, including 19-norandrosterone (19-NA), in 67 pregnant women and compared to postpartum. Epitestosterone was higher and, consequently, the T/E and 5αAdiol/E ratios were lower in the pregnant women. Androsterone/etiocholanolone (A/Etio) and 5αAdiol/5βAdiol, on the other hand, were higher in the first trimester as compared to postpartum (p<0.0001 and p=0.0396, respectively). There was no difference in A/T during pregnancy or after. 19-NA was present in 90.5% of the urine samples collected from pregnant women. In this study, we have shown that the steroid profile of the ABP is affected by pregnancy, and hence can cause atypical passport findings. These atypical findings would lead to unnecessary confirmation procedures, if the patterns of pregnancy are not recognized by the ABP management units. Copyright © 2018 John Wiley & Sons, Ltd.

Preferential Use of Central Metabolism In Vivo Reveals a Nutritional Basis for Polymicrobial Infection

Alteri, Christopher J.; Himpsl, Stephanie D.; Mobley, Harry L. T.

2015-01-01

The human genitourinary tract is a common anatomical niche for polymicrobial infection and a leading site for the development of bacteremia and sepsis. Most uncomplicated, community-acquired urinary tract infections (UTI) are caused by Escherichia coli, while another bacterium, Proteus mirabilis, is more often associated with complicated UTI. Here, we report that uropathogenic E. coli and P. mirabilis have divergent requirements for specific central pathways in vivo despite colonizing and occupying the same host environment. Using mutants of specific central metabolism enzymes, we determined glycolysis mutants lacking pgi, tpiA, pfkA, or pykA all have fitness defects in vivo for P. mirabilis but do not affect colonization of E. coli during UTI. Similarly, the oxidative pentose phosphate pathway is required only for P. mirabilis in vivo. In contrast, gluconeogenesis is required only for E. coli fitness in vivo. The remarkable difference in central pathway utilization between E. coli and P. mirabilis during experimental UTI was also observed for TCA cycle mutants in sdhB, fumC, and frdA. The distinct in vivo requirements between these pathogens suggest E. coli and P. mirabilis are not direct competitors within host urinary tract nutritional niche. In support of this, we found that co-infection with E. coli and P. mirabilis wild-type strains enhanced bacterial colonization and persistence of both pathogens during UTI. Our results reveal that complementary utilization of central carbon metabolism facilitates polymicrobial disease and suggests microbial activity in vivo alters the host urinary tract nutritional niche.

Infected kidney stones refer to stones that form because of urinary tract infections with urease-producing bacteria, secondarily infected stones of any composition, or stones obstructing the urinary tract leading to pyelonephritis. The mainstay of treatment of infection stones is complete stone removal. Kidney stones that obstruct the urinary tract and cause obstructive pyelonephritis are also frequently referred to as infected stones. Obstructive pyelonephritis is a urologic emergency as it can result in sepsis and even death. Infection stones and obstructive stones causing pyelonephritis are different disease processes, and their workup and management are described separately. Copyright © 2015 Elsevier Inc.

It inhabits the skin and mucous membranes, but it has rarely been isolated from clinical specimens and is thus considered to be a non-pathogenic commensal. However, it may cause opportunistic infections in patients with indwelling devices and severe underlying diseases. We are reporting an unusual case of a Kocuria kristinae urinary tract infection in a catheterized, 20-years old male. To the best of our knowledge, this is the first reported case of a catheter related urinary tract infection which was caused by Kocuria kristinae.

2012-09-01

Suprapubic catheterization is commonly used for postoperative bladder drainage after gynecologic procedures. However, recent studies have suggested an increased rate of complications compared with urethral catheterization. We undertook a systematic review and meta-analysis of randomized controlled trials comparing suprapubic catheterization and urethral catheterization in gynecologic populations. PubMed, EMBASE, CINAHL, Google Scholar, and trial registries were searched from 1966 to March 2012 for eligible randomized controlled trials comparing postoperative suprapubic catheterization and urethral catheterization in gynecologic patients. We used these search terms: "catheter," "supra(-)pubic catheter," "urinary catheter," "gyn(a)ecological," "catheterization techniques gyn(a)ecological surgery," "transurethral catheter," and "bladder drainage." No language restrictions were applied. METHODS AND STUDY SELECTION: The primary outcome was urinary tract infection. Secondary outcomes were the need for recatheterization, duration of catheterization, catheter-related complications, and duration of hospital stay. Pooled effect size estimates were calculated using the random effects model from DerSimonian and Laird. In total, 12 eligible randomized controlled trials were included in the analysis (N=1,300 patients). Suprapubic catheterization was associated with a significant reduction in postoperative urinary tract infections (20% compared with 31%, pooled odds ratio [OR] 0.31, 95% confidence interval [CI] 0.185-0.512, P<.01) but an increased risk of complications (29% compared with 11%, pooled OR 4.14, 95% CI 1.327-12.9, P=.01). Complications were mostly related to catheter tube malfunction with no visceral injuries reported. No differences in the rate of recatheterization or hospital stay were demonstrated. Robust patient satisfaction and cost-effectiveness data are lacking. Based on the best available evidence, no route for bladder drainage in gynecologic patients is clearly superior. The reduced rate of infective morbidity with suprapubic catheterization is offset by a higher rate of catheter-related complications and crucially does not translate into reduced hospital stay. As yet, there are insufficient data to determine which route is most appropriate for catheterization; therefore, cost and patient-specific factors should be paramount in the decision. Minimally invasive surgery may alter the requirement for prolonged postoperative catheterization.

Urinary tract infections (UTIs) are common in pregnant women and pose a great therapeutic challenge, since the risk of serious complications in both the mother and her child is high. Pregnancy is a state associated with physiological, structural and functional urinary tract changes which promote ascending infections from the urethra. Unlike the general population, all pregnant women should be screened for bacteriuria with urine culture, and asymptomatic bacteriuria must be treated in every case that is diagnosed, as it is an important risk factor for pyelonephritis in this population. The antibiotic chosen should have a good maternal and fetal safety profile. In this paper, current principles of diagnosis and management of UTI in pregnancy are reviewed, and the main problems and controversies are identified and discussed.

Three paraplegic patients with urinary tract infections caused by a beta-lactamase-producing Klebsiella pneumoniae were treated with a combination of amoxycillin and clavulanic acid (A-CA) (Augmentin; Beecham), after initial and unsuccessful therapy with amoxycillin alone. The administration of A-CA resulted in a rapid decrease in the urinary bacterial cell count, coupled with a dramatic increase in urinary amoxycillin concentrations.

Reversible tetraplegia after percutaneous nephrostolithotomy and septic shock: a case of critical illness polyneuropathy and myopathy with acute onset and complete recovery

PubMed Central

2013-01-01

Background Critical illness polyneuropathy (CIP) and critical illness myopathy (CIM) are complications causing weakness of respiratory and limb muscles in critically ill patients. As an important differential diagnosis of Guillain-Barré syndrome (GBS), CIP and CIM should be diagnosed with caution, after a complete clinical and laboratory examination. Although not uncommon in ICU, CIP and CIM as severe complications of percutaneous nephrostolithotomy (PNL) have not been documented in literature. Case presentation A 48-year-old Chinese woman was referred to our hospital, complaining of occasional pain in the right lower back for one month. Lithiasis was diagnosed by ultrasonographical and radiological examinations on the urinary system. PNL was indicated and performed. The patient developed CIP and CIM on the fourth day after PNL. Early recognition and treatment of the severe complications contributed to a satisfactory recovery of the patient. Conclusion This case expands our understanding of the complications of PNL and underscores the importance of differentiating CIP/CIM from GBS in case of such patients developing weakness after the treatment. Clinical characteristics and examination results should be carefully evaluated to make the diagnosis of CIP or CIM. Both anti-septic prophylaxis and control of hyperglycemia might be effective for the prevention of CIP or CIM; aggressive treatment on sepsis and multiple organ failure is considered to be the most effective measure to reduce the incidence of CIP/CIM.

This paper presents a case of a pregnant woman with a history of two cesarean sections. The patient was admitted to the hospital because of vaginal bleeding. The ultrasound revealed a placenta covering the internal os. The placenta was characterized by heterogeneous echogenicity with visible irregular hypoechogenic areas and blurred border between the placenta and the cervix. Rich vascularity was observed on the border of the placenta, urethra and the urinary bladder. Cystoscopy showed severe congestion around the urethra. On the back wall of the bladder a slightly increased vascularity was seen, which did not allow to confirm or exclude placental ingrowth in the urinary bladder. At 38 weeks, the patient was scheduled for an elective cesarean section. A classic perpendicular incision and leaving the placenta in the uterine cavity were proposed. After opening the abdomen, a strong vascularization in the region of lower part of the uterus and the urinary bladder was seen. Uterine incision in the fundus and the posterior wall was performed. A female fetus (weight: 2950g, Apgar: 10,10) was born. Then, the umbilical cord was ligated with non-absorbable suture and inserted back into the uterus. However, due to the presence of abundant and persistent vaginal bleeding during the next few minutes, conversion to obstetric hysterectomy was required. During relaparotomy fragments of the placenta appeared on the right side after sliding the urinary bladder. The bladder and the left ureter were damaged during surgery. The urinary bladder was sewn after removal of the uterus. Next, the urologist anastomosed end-to-end the left ureter on the pigtail catheter In the third hour of operation, cardiac arrest was caused by ventricular fibrillation. Immediate resuscitation with defibrillation allowed to restore normal function of the cardiovascular system. Total blood loss during the operation was 3000-4000 ml. During surgery 10 units of packed RBCs, 7 units of fresh frozen plasma, and 4 units of cryoprecipitate were transfused. The patient received antibiotics and anticoagulation therapy. Polyuria was diagnosed in the following days of puerperium, accompanied by electrolyte disturbances in serum and urine. The patient was treated with vasopressin and the electrolyte disturbances were corrected. On day 10 postpartum, the urinary catheter was removed, and clear significant improvement and stabilization of renal function and patient health were obtained. The patient was discharged from the hospital on day 19 of the puerperium. In summary it is clear that the steadily increasing rate of cesarean deliveries may result in the future in an increased number of abnormal placentation cases. Abnormal placentation is one of the most important risk factors of severe obstetric complications, including perinatal massive hemorrhage, which can lead to abnormal organ perfusion with cardiac arrest. Therefore, prenatal diagnosis and identification of abnormal placentation are vital in order to plan adequately the date, place, and mode of delivery as well as to ensure the availability of highly qualified specialists in the field of obstetrics and anesthesia, and organize sufficient amount of blood products and blood substitutes.

The definitions of acute and chronic urinary retention remain empirical and subject to wide interpretation. Standardized criteria have not been established and many questions remain unanswered. Moreover, the definition of significant post-void residual urine is unclear. We reviewed several aspects of urinary retention that require clarification with the objective of stimulating discussion among urologists to establish an accurate and coherent definition of urinary retention and significant post-void residual urine, and clarify risk factors. A MEDLINE search for articles written in English and published before April 2007 was done using a list of terms related to urinary retention. Articles not directly relevant to urinary retention or post-void residual urine were excluded. The term urinary retention lacks precise clinical or urodynamic meaning. Use of this term to describe a symptom, a sign, and a condition further complicates the issue. Many factors can contribute to the development of retention, including bladder outlet obstruction, detrusor underactivity, and neurogenic bladder conditions. Community based studies and clinical trials in patients with benign prostatic enlargement and/or lower urinary tract symptoms yield different estimates of the incidence of retention and only provide information on the epidemiology of acute urinary retention. However, age, previous retention episodes, lower urinary tract symptoms, chronic inflammation, serum prostate specific antigen level, prostate size, and urodynamic variables appear to be predictors of acute urinary retention. Alpha-receptor antagonists and 5alpha-reductase inhibitors may be useful in preventing urinary retention episodes and progressive benign prostatic enlargement. Clinical trials on the short-term use of antimuscarinics have not provided evidence that these agents increase the risk of retention; data on longer term administration are needed. Clinicians are adopting less invasive approaches (eg pharmacology or catheterization) to treating patients who present with the symptoms, sign, and condition of urinary retention. Faced with an abundance of new data on acute urinary retention, urologists need to reach a consensus about the risks of urinary retention; this may promote movement toward patient centered prevention strategies with tailored treatment options.

Purpose: To determine the feasibility of combined long-term androgen deprivation therapy (ADT) and dose escalation with high-dose-rate (HDR) brachytherapy. Methods and Materials: Between 2001 and 2007, 200 patients with high-risk prostate cancer (32.5%) or very high-risk prostate cancer (67.5%) were prospectively enrolled in this Phase II trial. Tumor characteristics included a median pretreatment prostate-specific antigen of 15.2 ng/mL, a clinical stage of T2c, and a Gleason score of 7. Treatment consisted of 54 Gy of external irradiation (three-dimensional conformal radiotherapy [3DCRT]) followed by 19 Gy of HDR brachytherapy in four twice-daily treatments. ADT started 0-3 months before 3DCRT and continuedmore » for 2 years. Results: One hundred and ninety patients (95%) received 2 years of ADT. After a median follow-up of 3.7 years (range, 2-9), late Grade {>=}2 urinary toxicity was observed in 18% of the patients and Grade {>=}3 was observed in 5%. Prior transurethral resection of the prostate (p = 0.013) and bladder D{sub 50} {>=}1.19 Gy (p = 0.014) were associated with increased Grade {>=}2 urinary complications; age {>=}70 (p = 0.05) was associated with Grade {>=}3 urinary complications. Late Grade {>=}2 gastrointestinal toxicity was observed in 9% of the patients and Grade {>=}3 in 1.5%. CTV size {>=}35.8 cc (p = 0.007) and D{sub 100} {>=}3.05 Gy (p = 0.01) were significant for increased Grade {>=}2 complications. The 5-year and 9-year biochemical relapse-free survival (nadir + 2) rates were 85.1% and 75.7%, respectively. Patients with Gleason score of 7-10 had a decreased biochemical relapse-free survival (p = 0.007). Conclusions: Intermediate-term results at the 5-year time point indicate a favorable outcome without an increase in the rate of late complications.« less

Although the negative aspects of blood transfusion are increasingly recognized, less is known about transfusion-related risks in spinal surgery. This study was designed to determine whether perioperative allogeneic blood transfusion is associated with increased risk of infectious complications after elective spinal surgery. A retrospective cohort study with propensity score matched analysis was carried out. Data of patients with spinal canal stenosis and spondylolisthesis who underwent elective lumbar surgeries (decompression or fusion) were obtained from the Diagnosis Procedure Combination database, a nationwide administrative inpatient database in Japan. Clinical outcomes included in-hospital death and the occurrence of infectious complications (surgical site infection [SSI], respiratory tract infection, urinary tract infection, and sepsis). Patients' clinical information, including sex, age, type of hospital, preoperative comorbidities, duration of anesthesia, cell saver use, and volume of allogeneic blood transfused, were investigated. Patients transfused with >840 mL (6 units) were excluded. Propensity scores for receiving transfusion were calculated, with one-to-one matching based on estimated propensity scores to adjust for patients' baseline characteristics. The proportions of complications were compared in patients with and without transfusions. This study was funded by grants from the Ministry of Health, Labour and Welfare, Japan. Of the 84,650 patients identified, 5,289 patients (6.1%) received transfusions, with 4,436 (5.2%) receiving up to 840 mL. One-to-one propensity score matching resulted in 4,275 pairs with and without transfusion. Patients transfused were at increased risk of SSI (odds ratio [OR], 1.9; 95% confidence interval [CI], 1.4-2.5; p<.001) and urinary tract infection (OR, 2.5; 95% CI, 1.5-4.2; p<.001) than those not transfused. Allogeneic blood transfusion after elective lumbar surgery was associated with increased risks of SSI and urinary tract infection. Copyright © 2015 Elsevier Inc. All rights reserved.

Objective: Ho:YAG laser had been used to treat the common diseases of urinary system such as bladder cancer and benign prostatic hyperplasia in our hospital. This study is to assess the efficacy and safety of transurethral Ho:YAG-laser resection to treat the urethral stricture and bladder neck contracture. Methods: From May 1997 to August 2004, 26 cases of urethral stricture and 33 cases of bladder neck contracture were treated by transurethral Ho:YAG-laser resection. These patients were followed up at regular intervals after operation. The uroflow rate of these patients was detected before and one-month after operation. The blood loss and the energy consumption of holmium-laser during the operation as well as the complications and curative effect after operation were observed. Results: The therapeutic effects were considered successful, with less bleeding and no severe complications. The Qmax of one month postoperation increased obviously than that of preoperation. Of the 59 cases, restenosis appeared in 11 cases (19%) with the symptoms of dysuria and weak urinary stream in 3-24 months respectively. Conclusions: The Ho:YAG-laser demonstrated good effect to treat the obstructive diseases of lower urinary tract such as urethral stricture and bladder neck contracture. It was safe, minimal invasive and easy to operate.

To identify symptom distress and clusters in patients 3 months after radical cystectomy and to explore their potential predictors. A cross-sectional design was used to investigate 99 bladder cancer patients 3 months after radical cystectomy. Data were collected by demographic and disease characteristic questionnaires, the symptom experience scale of the M.D. Anderson symptom inventory, two additional symptoms specific to radical cystectomy, and the functional assessment of cancer therapy questionnaire. A factor analysis, stepwise regression, and correlation analysis were applied. Three symptom clusters were identified: fatigue-malaise, gastrointestinal, and psycho-urinary. Age, complication severity, albumin post-surgery (negative), orthotropic neobladder reconstruction, adjuvant chemotherapy and American Society of Anesthesiologists (ASA) scores were significant predictors of fatigue-malaise. Adjuvant chemotherapy, orthotropic neobladder reconstruction, female gender, ASA scores and albumin (negative) were significant predictors of gastrointestinal symptoms. Being unmarried, having a higher educational level and complication severity were significant predictors of psycho-urinary symptoms. The correlations between clusters and for each cluster with quality of life were significant, with the highest correlation observed between the psycho-urinary cluster and quality of life. Bladder cancer patients experience concurrent symptoms that appear to cluster and are significantly correlated with quality of life. Moreover, symptom clusters may be predicted by certain demographic and clinical characteristics.

The objectives were to determine the prevalence of atypical presentations among older adults at the Emergency Department (ED) of a tertiary care hospital and to identify factors associated with these presentations. A retrospective medical record audit was randomly reviewed in 633 patients who were aged ≥ 65 years who attended the ED of Srinagarind Medical School Hospital in 2013. Demographic data were collected and were analyzed using descriptive statistics. Regression analysis was used to analyze the variables associated with the outcomes. The prevalence of an atypical presentation was 28.6% (181/633 cases). The failure to develop fever with a disease known to cause fever was the most common atypical presentation of illness (34.42%). Independent factors associated with atypical presentations were complicated urinary tract infection (UTI) (odds ratios (OR) 4.66, 95% confidence interval (CI) 2.0, 10.84, p=0.00) and a background of dementia (OR 3.48, 95% CI 1.38, 8.77, p=0.008). The prevalence of atypical presentations of older adults at the ED was about a third. The absence of fever with a disease known to cause fever was the most common atypical presentation. Complicated UTI and demented patients were the independent risk factors associated with the atypical presentations. Early awareness of non-specific presentations and applying comprehensive geriatric assessments among older patients at the ED is recommended. Copyright © 2015 Elsevier Ireland Ltd.

Increased Incidence of Urolithiasis and Bacteremia During Proteus mirabilis and Providencia stuartii Coinfection Due to Synergistic Induction of Urease Activity

PubMed Central

Armbruster, Chelsie E.; Smith, Sara N.; Yep, Alejandra; Mobley, Harry L. T.

2014-01-01

Background. Catheter-associated urinary tract infections (CaUTIs) are the most common hospital-acquired infections worldwide and are frequently polymicrobial. The urease-positive species Proteus mirabilis and Providencia stuartii are two of the leading causes of CaUTIs and commonly co-colonize catheters. These species can also cause urolithiasis and bacteremia. However, the impact of coinfection on these complications has never been addressed experimentally. Methods. A mouse model of ascending UTI was utilized to determine the impact of coinfection on colonization, urolithiasis, and bacteremia. Mice were infected with P. mirabilis or a urease mutant, P. stuartii, or a combination of these organisms. In vitro experiments were conducted to assess growth dynamics and impact of co-culture on urease activity. Results. Coinfection resulted in a bacterial load similar to monospecies infection but with increased incidence of urolithiasis and bacteremia. These complications were urease-dependent as they were not observed during coinfection with a P. mirabilis urease mutant. Furthermore, total urease activity was increased during co-culture. Conclusions. We conclude that P. mirabilis and P. stuartii coinfection promotes urolithiasis and bacteremia in a urease-dependent manner, at least in part through synergistic induction of urease activity. These data provide a possible explanation for the high incidence of bacteremia resulting from polymicrobial CaUTI. PMID:24280366

To determine the epidemiology of urological emergencies in a university hospital and the interest of a dedicated urological emergency unit. In 2008, a dedicated urological emergency unit was individualized in our department of urology. We conducted a retrospective study including all patients consulting in this unit in 2009 with epidemiological, clinical and therapeutic data. During 2009, 1257 patients consulted in this unit. Main diagnoses were acute urinary retention (303, 24.11%), renal colic (219, 17.42%), urinary infections (278, 22.11%), postoperative complications (141, 11.22%), symptomatic benign prostate hyperplasia (65, 5.17%), genitourinary cancers (61, 4.85%), trauma of urinary apparel (41, 3.26%), and spermatic cords torsion (10, 0.8%). In 99 cases (7.88%) diagnosis did not involved the urinary system. The treatment was surgical in 213 (17.7%) cases, technical procedure under local anesthesia in 368 (29.3%) and a medical treatment in 675 (53.7%) cases. Six hundred and sixty (52.5%) patients were managed ambulatory whereas 596 (47.5%) needed hospitalization. The opening of a dedicated urological emergency unit lead to 1257 emergency consultations. Frequent etiologies were acute urinary retention, renal colic and urinary infection. The creation of this unit allowed to register and to valorize this emergency activity through the ATU emergency amount. Copyright © 2013. Published by Elsevier Masson SAS.

Proteus mirabilis and Urinary Tract Infections

Schaffer, Jessica N.; Pearson, Melanie M.

2015-01-01

Proteus mirabilis is a Gram-negative bacterium which is well-known for its ability to robustly swarm across surfaces in a striking bulls’-eye pattern. Clinically, this organism is most frequently a pathogen of the urinary tract, particularly in patients undergoing long-term catheterization. This review covers P. mirabilis with a focus on urinary tract infections (UTI), including disease models, vaccine development efforts, and clinical perspectives. Flagella-mediated motility, both swimming and swarming, is a central facet of this organism. The regulation of this complex process and its contribution to virulence is discussed, along with the type VI-secretion system-dependent intra-strain competition which occurs during swarming. P. mirabilis uses a diverse set of virulence factors to access and colonize the host urinary tract, including urease and stone formation, fimbriae and other adhesins, iron and zinc acquisition, proteases and toxins, biofilm formation, and regulation of pathogenesis. While significant advances in this field have been made, challenges remain to combatting complicated UTI and deciphering P. mirabilis pathogenesis. PMID:26542036

Complications in urinary tract nervous routes due to herpes viruses as VZV and HSV-2 are well known. Acute urinary retention and chronic neuropathic pain are not rare when sacral dermatomes are involved by these viruses. However, an analogous condition has not yet been clearly ascribed to HSV-1 infection. We present a 32-year-old immunocompetent patient with fever, lumbar pain and acute urinary retention who had never had herpetic clinical manifestations. Urodynamic studies diagnosed a neurologic bladder with an absent filling sensation. Cystoscopic assessment revealed the presence of reddened and isolated small mucosal areas in the bladder walls. The search for herpes viruses in plasma and CSF by PCR assay were positive for HSV-1. After treatment with antiviral therapy the disease resolved. Intermittent catheterization was necessary and voiding dysfunction resolved after three weeks by its appearance. Neurological damage to the central nervous system (CNS) and/or PNS due to HSV-1 seems to be the most likely reason. The course of disease was benign and self-remitting.

Few studies of hypospadias repair in childhood have used validated questionnaires to investigate outcomes of cosmesis, urinary function, and sexual function in adulthood. We sought to investigate long-term outcomes in adult patients who had undergone severe hypospadias repair as children using an existing web-based application available to multiple institutions in order to develop an online patient survey of previously validated questionnaires. Patients aged 18 years or older who underwent severe hypospadias repair between 1992 and 1997 at our institution were contacted to complete an online survey. Through medical chart reviews, we analyzed the location of meatus, type of repair, and complications. The online survey included questions about penile appearance, and validated questionnaires to assess urinary and sexual function. Of 58 patients who met the inclusion criteria, we contacted 19, and 13 completed the survey. Fifty-nine percent had complications, with an average of 2.2 procedures per patient. Most (85.0%) were satisfied with penile appearance, although 38.0% had residual penile curvature. Hypospadias patients had mean lower orgasmic function than normal controls. Mean scores for urinary function and other domains of sexual function were similar to normal controls. Although the majority of adult patients were satisfied with the outcomes of penile appearance, urinary function, and sexual function, our online survey suggests decreased lower orgasmic function as measured by validated questionnaire. An online survey accessible to multiple institutions with validated questionnaires may facilitate assessment of long-term hypospadias results. Copyright © 2014 Journal of Pediatric Urology Company.

BackgroundWe aimed to evaluate the effectiveness of PAE in weaning of catheter and relieving obstructive urinary symptoms in patients with acute urinary retention (AUR) due to benign prostatic hypertrophy (BPH) and failed trial without catheter (TWOC).Materials and MethodsIn this prospective study approved by the institutional review board, a signed informed consent was obtained. Eighteen consecutive patients with AUR due to BPH and failed TWOC were recruited. Nineteen consecutive patients with BPH but without AUR were recruited as a control. Patients with CTA evidence of arterial occlusion or significant stenosis along the prostate artery access path were excluded. PAE was performedmore » using microspheres (100–300 μm diameter). Outcome assessment included successful weaning of catheter in 2 weeks, procedure-related complications, change of symptomatology and urodynamic findings at 1 month as compared to baseline, percent non-perfused prostate volume, and prostate volume reduction on MRI at 2 weeks.ResultsTwo patients in the study group and four in the control group were excluded due to arterial pathology. Embolization of bilateral prostate arteries was achieved in all patients in both the groups (100%). There was no complication. The catheter was successfully weaned in 87.5% (14/16) of patients within 14 days in the treatment group. There was no significant difference in patient demographics, prostate characteristics, and all outcome assessment parameters between both the groups.ConclusionsPAE was probably safe and effective in weaning of catheter and relieving obstructive urinary symptoms in patients due to BPH, with treatment outcomes comparable to those without AUR.« less

To describe our experience with concomitant repair of urethral diverticula and stress urinary incontinence (SUI) with autologous pubovaginal sling (PVS). A retrospective chart review between January 2006 and 2013 identified 38 women undergoing concomitant diverticulectomy and rectus sheath PVS. Patient demographics, presenting symptoms, prior urethral surgery, concomitant procedures, postoperative outcomes, and complications were evaluated. The mean duration of symptoms was 56.7 months. Eleven patients presented with recurrent diverticula and 5 patients had prior SUI surgery (3 midurethral slings, 1 PVS, and 1 bulking agent). One patient had a prior urethrolysis. All other slings were cut or excised at the time of surgery. All women had demonstrable SUI on cough stress test or urodynamics. The mean follow-up was 12.7 months. All postoperative voiding cystourethrograms were negative for contrast extravasation. One patient required prolonged (>4 weeks) suprapubic tube drainage for urinary retention. Four others required an additional 1 week of suprapubic tube drainage. Eighteen patients (47%) reported mixed urinary symptoms. Of these, 9 had complete resolution, whereas 9 experienced significant improvement. Overall, 97.3% reported resolution of their dysuria, dyspareunia, and pain symptoms and 90% reported complete resolution of their SUI symptoms. There were 2 urethral diverticula recurrences and 2 SUI recurrences. Perioperative complications, including hemorrhage, sling erosion, or urethrovaginal fistulas, were not observed. Concomitant PVS placement is a safe and effective treatment option for SUI in patients undergoing urethral diverticulectomy. The risks and benefits should be weighed and management individualized.

Bacterial resistance to antibiotics is associated with morbidity, mortality, and an increase in cost. Our objective was to assess bacterial resistance from cultures of patients with non-complicated urinary tract infection (UTI). We analyzed antibiotic resistance using the VITEK-II system among patients attending the internal medicine unit with non-complicated UTI. 1,479 urine cultures were performed; we excluded: 98 due to contamination, 924 had no bacterial growth, and 57 had missing data. Among the 404 samples that were positive, 240 were found among out patients and 164 among hospitalized patients. E coli were the most frequent pathogen, followed by Enterococcus, and K pneumonia, in out patients; E coli, P aeruginosa, and fungal infections (23% of cases) in hospitalized patients. Samples with E coli among out patients displayed resistance of 50% to fluoroquinolones and 55% to sulfas. Among hospitalized patients, resistance was observed in 71 and 66% respectively. Resistance to P aeruginosa was 38% for amynoglucosides and carbapenems and 100% for piperacillin; Enterococcus had 50% for fluoroquinolones. E. coli is the most common pathogen among UTI patients. We must adapt guidelines to recommend antibiotics and design a comprehensive control program to reduce the high levels of bacterial antibiotic resistance among our population.

2011-01-01

Various types and materials of stents have been used for urinary diversion in hypospadias surgery. We evaluated whether double pigtail stents are superior to straight silicone stents. We conducted a retrospective chart review of all patients who underwent hypospadias surgery with straight silicone or double pigtail stents between November 1997 and October 2005. Comparisons were made between the two groups specifically with regard to the complication rates. A total of 86 patients were included. The complication rates in patients who received double pigtail stents were significantly reduced as compared with those who received straight silicon stents. There was less wound disruption associated with early stent dislodgement in the double pigtail group compared with the straight silicone group (3.2%vs. 17.4%, p< 0.05). The rate of urethrocutaneous fistula was also lower in the double pigtail stent group (12.7%vs. 30.4%). Subjectively, there was also improved patient comfort and parent anxiety in the double pigtail stent group. Double pigtail stent is a suitable material for urinary diversion in hypospadias surgery. It not only reduces patient discomfort, but also decreases complication rates in hypospadias surgery. Copyright © 2011 Asian Surgical Association. Published by Elsevier B.V. All rights reserved.

Peco-Antić, Amira; Miloševski-Lomić, Gordana

2015-01-01

A normal development of lower urinary tract function control evolves from involuntary bladder empting (incontinence) during infancy to daytime urinary continence, and finally a successful day and night continence that is generally achieved by the 5th to 7th year of age.This gradual process primarily depends on the progressive maturation of the neural control of the lower urinary tract, but it is also influenced by behavioral training that evolves through social support. Functional voiding disorders (bladder dysfunction) are common problems during childhood. They are present in 5-15 % of general pediatric population, and in one-fifth of school-age children or in over one-third of patients of the pediatric urologist or nephrologist. More than half of children with bladder dysfunction have vesicoureteral reflux, and more than two-thirds have recurrent urinary tract infections. There is also a frequent association of bladder dysfunction with constipation and encopresis (dysfunctional elimination syndrome). Bladder dysfunction may cause a permanent damage to the upper urinary tract and kidneys. In addition, urinary incontinence, as the most common manifestation of bladder dysfunction can be the cause of major stress in school- age children and have a negative effect on the child's feeling of self-esteem. Thus, a timely detection and treatment of this group of disorders in children is highly significant.

Acid-base metabolism: implications for kidney stones formation.

PubMed

Hess, Bernhard

2006-04-01

The physiology and pathophysiology of renal H+ ion excretion and urinary buffer systems are reviewed. The main focus is on the two major conditions related to acid-base metabolism that cause kidney stone formation, i.e., distal renal tubular acidosis (dRTA) and abnormally low urine pH with subsequent uric acid stone formation. Both the entities can be seen on the background of disturbances of the major urinary buffer system, NH3+ <--> NH4+. On the one hand, reduced distal tubular secretion of H+ ions results in an abnormally high urinary pH and either incomplete or complete dRTA. On the other hand, reduced production/availability of NH4+ is the cause of an abnormally low urinary pH, which predisposes to uric acid stone formation. Most recent research indicates that the latter abnormality may be a renal manifestation of the increasingly prevalent metabolic syndrome. Despite opposite deviations from normal urinary pH values, both the dRTA and uric acid stone formation due to low urinary pH require the same treatment, i.e., alkali. In the dRTA, alkali is needed for improving the body's buffer capacity, whereas the goal of alkali treatment in uric acid stone formers is to increase the urinary pH to 6.2-6.8 in order to minimize uric acid crystallization.

Comprehensive and standardized reporting of adverse events after robot-assisted radical cystectomy (RARC) and urinary diversion for bladder cancer is necessary to evaluate the magnitude of morbidity for this complex operation. To accurately identify and assess postoperative morbidity after RARC using a standardized reporting system. A total of 241 consecutive patients underwent RARC, extended pelvic lymph node dissection, and urinary diversion between 2003 and 2011. In all, 196 patients consented to a prospective database, and they are the subject of this report. Continent diversions were performed in 68% of cases. All complications within 90 d of surgery were defined and categorized by a five-grade and 10-domain modification of the Clavien system. Univariable and multivariable logistic regression analyses were used to identify predictors of complications. Grade 1-2 complications were categorized as minor, and grade 3-5 complications were categorized as major. All blood transfusions were recorded as grade ≥2. Eighty percent of patients (156 of 196 patients) experienced a complication of any grade ≤90 d after surgery. A total of 475 adverse events (113 major) were recorded, with 365 adverse events (77%) occurring ≤30 d after surgery. Sixty-eight patients (35%) experienced a major complication within the first 90 d. Other than blood transfusions given (86 patients [43.9%]), infectious, gastrointestinal, and procedural complications were the most common, at 16.2%, 14.1%, and 10.3%, respectively. Age, comorbidity, preoperative hematocrit, estimated blood loss, and length of surgery were predictive of a complication of any grade, while comorbidity, preoperative hematocrit, and orthotopic diversion were predictive of major complications. The 90-d mortality rate was 4.1%. The main limitation is lack of a control group. Analysis of postoperative morbidity following RARC demonstrates a considerable complication rate, though the rate is comparable to contemporary open series that followed similar reporting guidelines. This finding reinforces the need for complete and standardized reporting when evaluating surgical techniques and comparing published series. Copyright © 2012 European Association of Urology.

Urinary calculi: microbiological and crystallographic studies.

PubMed

Rosenstein, I J

1986-01-01

Although referred to as "urinary calculus disease", the formation of stone in the urinary tract is not caused by a single etiological agent. As such, diverse clinical investigations to diagnose the cause of stone formation must be carried out and the course of management after diagnosis must inevitably be different in each case. This review will cover all aspects of calculus formation, but will give particular attention to calculi caused by infection of the urinary tract with urease-producing bacteria. This is a recurrent, potentially life-threatening disease which has led clinicians to refer to the condition as "stone cancer". Because the etiology of infection stones is so different from stones caused by metabolic disorders, the two disease patterns should be considered separately, a fact often overlooked in epidemiological studies of stone formation. The importance of analysis of calculi as an aid to management is thus emphasized; identification of stone type will help to indicate appropriate therapy. A review of methods of analysis will be covered, particularly crystallographic analysis. Inhibition of bacterial urease as a means of management of infection stones will be discussed together with problems encountered and brighter hopes for the future.

Objective. To observe the clinical prophylactic and therapeutic efficacy of Liuwei Dihuang Pills and Ginkgo Leaf Tablets for type 2 diabetic vascular complications. Methods. It was a randomized, double-blind and placebo-controlled clinical trial. 140 outpatients with type 2 diabetes were recruited and randomly divided into the treatment group and control group. The two groups were given basic therapy (management of blood sugar, blood pressure, etc.). Additionally, the treatment group was given Liuwei Dihuang Pills and Ginkgo Leaf Tablets, while the control group was given Liuwei Dihuang Pills and Ginkgo Leaf Tablets placebos. All subjects were followed up for consecutive 36 months and observed monthly. The clinical data as urinary microalbumin to urinary creatinine ratio (Umalb/cr), carotid intima-media thickness (IMT), diabetic nephropathy (DN) and diabetic retinopathy (DR) prevalence, cardiovascular and cerebrovascular events, blood glucose, and blood pressure were collected and analyzed statistically. Results. After 36-month treatment, the Umalb/cr level and DN and DR prevalence in treatment group were all significantly lower than control group ( P < 0.05). However, the IMT level and the incidence of cardiovascular and cerebrovascular events were not significantly different between the two groups ( P > 0.05). Conclusions. Liuwei Dihuang Pills and Ginkgo Leaf Tablets are beneficial to diabetic microvascular complications, while the efficacy to diabetic macrovascular complications needs more observations.

To describe the antenatal complications, mode of delivery and outcome of pregnancy in women with spina bifida. Case series of women known to have attended the spina bifida clinic at the Royal Children's Hospital. Medical records, postal questionnaire and telephone interview were utilized to collect data on the effect of pregnancy on the health of women and the effect of spina bifida on pregnancy outcome. Of 207 women born between 1945 and 1975, 23 reported having a pregnancy, and 17 who had completed pregnancies agreed to participate. The 17 women had a total of 29 pregnancies, with 23 pregnancies progressing to births. Fourteen of 17 women had antenatal admissions, with wheelchair-dependent women requiring more-frequent and longer admissions. Recurrent urinary infections in pregnancy occurred in women with a prior history of urinary infections; stomal problems occurred but were not serious; mobility was reduced for two women during pregnancy, with full recovery afterwards; and preexisting pressure sores worsened during pregnancy. Vaginal deliveries occurred in one in five pregnancies of women who were wheelchair dependent and in ten of eighteen pregnancies in independently mobile women, including seven of eight pregnancies of independently mobile women without ileal conduits. Cesarean sections were accompanied by postoperative complications in 10 women. Women with spina bifida who become pregnant generally have a positive outcome, with relatively low complication rates.

Midurethral Slings for Women with Stress Urinary Incontinence

PubMed Central

2006-01-01

Executive Summary Objective The objective of the current review was to evaluate the safety, efficacy, and cost-effectiveness of midurethral slings compared with traditional surgery. Background This assessment was undertaken in order to update and expand upon the health technology & policy assessment of tension-free vaginal tape (TVT, Gynecare Worldwide, a division of Ethicon Inc, a Johnson & Johnson company, Somerville, New Jersey) sling procedure for stress urinary incontinence published by the Medical Advisory Secretariat in February 2004. Since the publication of the 2004 assessment, a number of TVT-like sling alternatives have become available which employ the same basic principles as TVT slings: minimally invasive, midurethral placement, self-fixing, and tension-free. This update will evaluate the efficacy and safety of midurethral slings. Clinical Need Normal continence is controlled by the nervous system and involves co-ordination between bladder, urethra, urethral sphincter, and pelvic floor. Incontinence occurs when the relationship among the above components is compromised, either due to physical damage or nerve dysfunction. (1) Stress urinary incontinence is the most common form of urinary incontinence in women. It is characterized by the “complaint of involuntary leakage on effort or exertion, or on sneezing or coughing” when there is increased abdominal pressure without detrusor (bladder wall) contraction. (2) There are 2 factors which define stress urinary incontinence: a weakening in the support of the proximal urethra, causing urethral hyper-mobility and deficiency in the sphincter, causing urethral leakage. Both factors are thought to coexist. (1) Accurate tests are not available to distinguish these 2 types of stress urinary incontinence. Urinary incontinence is estimated to affect about 250,000 Canadian women and 8 million American women aged 65 and over. (3;4) The prevalence of stress urinary incontinence is very difficult to measure because women with stress urinary incontinence may not tell their health practitioner about their symptoms due to embarrassment associated with stress urinary incontinence. A cross-sectional postal survey of 15,904 adults aged 40 and over who were registered with a local GP in Leicestershire, United Kingdom, revealed that 18% to 34% of respondents had symptoms of SUI. (5) Just over 9% reported symptoms “sometimes,” while almost 3% reported symptoms “most of the time.” Stress urinary incontinence was most common for women in their 50s. A more recent study suggests that 24% of women aged 18 to 44 years and 37% of women aged 45 and over have symptoms of stress urinary incontinence. (6) Stress urinary incontinence has been associated with a broad range of psychosocial stress and disablement, such as difficulties with activities of daily living, avoidance of social activities, fear of unpleasant odour, and embarrassment. (7) Economic burden may include the cost of pads, drugs, and devices, and the inability to participate in the work force in severe cases. Midurethral Slings Suburethral slings differ according to several criteria including placement, approach, method of fixation, and sling material. This review will evaluate slings which fulfill all of the following criteria: Midurethral placement (as opposed to bladder neck placement) Self-fixing (no sutures, bone anchors, etc.) Minimally invasive (using local, epidural, or general anesthesia) “Tension-free” placement The different types of midurethral slings available vary according to 3 main parameters: Implant material, i.e., monofilament, multifilament, elastic, non-elastic, smooth, serrated, etc., Delivery instruments, i.e., needles, curved trocars, disposable, reusable, etc., Surgical approach As any one, or any combination of these parameters may vary across the different sling brands, it is difficult to ascribe observed differences in efficacy and safety across slings to any one factor. Review Strategy The literature published between January 2000 and February 2006 was searched in the following databases: OVID Medline, In Process and Other Non-Indexed Citations, Embase, Cochrane Database of Systematic Reviews and CENTRAL, INAHTA. The database search was supplemented with a search of relevant Web sites, and a review of the bibliographies of selected papers. The search strategy can be viewed in Appendix 1. Inclusion Criteria General population with SUI Randomized controlled studies, health technology assessments, guidelines Female subjects Midurethral, self-fixing, and minimally invasive slings/tapes English language The search strategy yielded 391 original citations. Studies were excluded for a variety of reasons, such as using traditional, suburethral slings as opposed to midurethral slings, not including patients with stress urinary incontinence, including males in the study, case reports, and not reporting the outcomes of interest. There were 13 randomized controlled trials identified that compared midurethral slings to other midurethral slings or traditional surgery. (8-20) (Table 1) Three of the randomized controlled trials (15;17;20) have had subsequent updated articles of longer term results. (21-23) The results of the randomized controlled trials have been stratified into 2 groups: TVT versus colposuspension and comparisons of midurethral slings. No randomized controlled trials were identified that compared a midurethral sling other than TVT to colposuspension. Summary of Findings Effectiveness At this time, there does not appear to be one procedure that is more effective than another at curing stress urinary incontinence. TVT appears to have similar cure rates to open colposuspension; and the various midurethral sling types seem to have similar cure rates. Procedure Time and Length of Hospital Stay The procedure time and the length of hospital stay for TVT are significantly shorter than the procedure time and length of stay for colposuspension. The procedure time and length of hospital stay for all midurethral slings appears to be similar. Complications The most frequently reported complications were bladder perforations, de novo voiding difficulties and device problems. Quality of Life Quality of life was not consistently reported in all of the randomized controlled trials. In the studies that reported quality of life there does not appear to be a significant difference in quality of life scores between the sling procedures. PMID:23074494

Treatments for symptomatic urinary tract infections during pregnancy.

PubMed

Vazquez, Juan C; Abalos, Edgardo

2011-01-19

Urinary tract infections, including pyelonephritis, are serious complications that may lead to significant maternal and neonatal morbidity and mortality. There is a large number of drugs, and combination of them, available to treat urinary tract infections, most of them tested in non-pregnant women. Attempts to define the optimal antibiotic regimen for pregnancy have, therefore, been problematic. The objective of this review was to determine, from the best available evidence from randomised controlled trials, which agent is the most effective for the treatment of symptomatic urinary tract infections during pregnancy in terms of cure rates, recurrent infection, incidence of preterm delivery and premature rupture of membranes, admission to neonatal intensive care unit, need for change of antibiotic, and incidence of prolonged pyrexia. We searched the Cochrane Pregnancy and Childbirth Group Trials Register (November 2009) and reference lists of articles. We considered all trials where the intention was to allocate participants randomly to one of at least two alternative treatments for any symptomatic urinary tract infection. Both review authors assessed trial quality and extracted data. We included 10 studies, recruiting a total of 1125 pregnant women. In most of the comparisons there were no significant differences between the treatments under study with regard to cure rates, recurrent infection, incidence of preterm delivery, admission to neonatal intensive care unit, need for change of antibiotic and incidence of prolonged pyrexia. When cefuroxime and cephradine were compared, there were better cure rates (29/49 versus 41/52) and fewer recurrences (20/49 versus 11/52) in the cefuroxime group. There was only one other statistically significant difference when comparing outpatient versus inpatient treatment. Gestational age at birth was greater in women from the outpatient group (38.86 versus 37.21), while birthweight was on average greater in the inpatient group (3120 versus 2659). Although antibiotic treatment is effective for the cure of urinary tract infections, there are insufficient data to recommend any specific drug regimen for treatment of symptomatic urinary tract infections during pregnancy. All the antibiotics studied were shown to be very effective in decreasing the incidence of the different outcomes. Complications were very rare. All included trials had very small sample sizes to reliably detect important differences between treatments. Future studies should evaluate the most promising antibiotics, in terms of class, timing, dose, acceptability, maternal and neonatal outcomes and costs.

The management of urinary tract infections in octogenarian women.

Urinary Tract Infections are common in women of all ages and the incidence increases with age. Whilst they are a common cause of lower urinary tract symptoms in all women they may be associated with increased morbidity in the elderly. Appropriate investigation and treatment in primary and secondary care are essential to effectively manage urinary tract infection and decrease morbidity and hospitalisation rates. Loss of endogenous oestrogen at the time of the menopause is associated with the urogenital atrophy and an increased incidence of urinary tract infection. Consequently vaginal oestrogen therapy may offer a rationale for treatment and prevent of urinary tract infection. The aim of this paper is to review the clinical management of elderly women presenting with primary and recurrent urinary tract infection. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

Objective This study aimed to compare the effectiveness and complications between the retropubic and transobturator approaches for the treatment of female stress urinary incontinence (SUI) by conducting a systematic review. Materials and Methods We selected all randomized controlled trials (RCTs) that compared retropubic and transobturator sling placements for treatment of SUI. We estimated pooled odds ratios and 95% confidence intervals for intraoperative and postoperative outcomes and complications. Results Six hundred twelve studies that compared retropubic and transobturator approaches to midurethral sling placement were identified, of which 16 were included in our research. Our study was based on results from 2646 women. We performed a subgroup analysis to compare outcomes and complications between the two approaches. The evidence to support the superior approach that leads to better objective/subjective cure rate was insufficient. The transobturator approach was associated with lower risks of bladder perforation (odds ratio (OR) 0.17, 95% confidence interval (CI) 0.09-0.32), retropubic/vaginal hematoma (OR 0.32, 95% CI 0.16-0.63), and long-term voiding dysfunction (OR 0.32, 95% CI 0.17-0.61). However, the risk of thigh/groin pain seemed higher in the transobturator group (OR 2.53, 95% CI 1.72-3.72). We found no statistically significant differences in the risks of other complications between the two approaches. Conclusions This meta-analysis shows analogical objective and subjective cure rates between the retropubic and transobturator approaches to midurethral sling placement. The transobturator approach was associated with lower risks of several complications. However, good-quality studies with long-term follow-ups are warranted for further research. PMID:26005962

To investigate whether children with lower urinary tract (LUT) anomalies are at greater risk for postoperative complications after laparoscopic pyeloplasty stented with a double-J catheter (JJC). Prospectively collected data of laparoscopic pyeloplasty (LP) performed between 2006 and 2015 were analyzed. Inclusion criteria are (1) toilet-trained child and (2) unilateral dismembered pyeloplasty stented with a JJC done by the same surgeon. Our pyeloplasty protocol includes cystoscopy and retrograde pyelography. JJC is left in for 3weeks. Asymptomatic patients with infravesical LUT anomalies (a-LUTA) and those with history of LUT symptoms (LUTS) were identified. Any short-term complication was classified according to Clavien-Dindo. Fisher's exact test was used for statistical analysis. Fifty-four children (mean 9.8 years) were included. Ten of 54 patients had LUTS. In 4 of those 10, anatomical infravesical anomaly was found during cystoscopy. Accidental urethral anomaly was found in 11 patients (a-LUTA). The control group (CG) consisted of 33 patients. Postoperative hospital stay ranged from 1 to 8 days (mean 2 days). Overall complication rate was 8 of 54 (14%). Grade 1 complications occurred in 3 patients in the CG. Five patients had grade 3 complications (2 needed replacement of bladder catheter, and 3 had diversion of the upper tract). Those problems occurred in 1 of 10 patients with LUTS and 3 of 11 patients with a-LUTA compared to 1 of 33 in the CG. This difference was statistically significant (P < .05). Careful history should be taken in toilet-trained children before pyeloplasty. If any infravesical abnormality is discovered, internal diversion should probably be avoided. Special attention must be paid to bladder function in the postoperative period. Copyright © 2016 Elsevier Inc. All rights reserved.

Anterior Urethral Valve: A Rare But an Important Cause of Infravesical Urinary Tract Obstruction.

PubMed

Parmar, Jitendra P; Mohan, Chander; Vora, Maulik P

2016-01-01

Urethral valves are infravesical congenital anomalies, with the posterior urethral valve (PUV) being the most prevalent one. Anterior urethral valve (AUV) is a rare but a well-known congenital anomaly. AUV and diverticula can cause severe obstruction, whose repercussions on the proximal urinary system can be important. Few cases have been described; both separately and in association with urethral diverticulum. The presentation of such a rare but important case led us to a report with highlighting its classic imaging features. We present a case report of AUV with lower urinary tract symptoms in a 6-year-old boy with complaints of a poor stream of urine and strain to void. Unique findings were seen on Retrograde Urethrography (RGU) and Voiding Cysto-Urethrography (VCUG), i.e. linear incomplete filling defect in the penile urethra and associated mild dilatation of the anterior urethra ending in a smooth bulge. On cysto-urethroscopy the anterior urethral valve was confirmed and fulguration was done. Congenital anterior urethral valve is an uncommon but important cause of infravesical lower urinary tract obstruction that is more common in male urethra. It can occur as an isolated AUV or in association with diverticulum and VATER anomalies. Early diagnosis and management of this rare condition is very important to prevent further damage, infection and vesicoureteral reflux. AUV may be associated with other congenital anomalies of the urinary system; therefore a full evaluation of the urinary system is essential.

The effect of abdominal pressure on urinary flow rate.

1983-07-01

We examined the effect of abdominal pressure on urinary flow rate and urethral closure pressure in 46 subjects, ranging in age from 26 to 82 years. An increase in urinary flow rate caused by abdominal straining was not found when organic obstruction was present in the prostatic urethra in men or the proximal urethra in women, or when dysuria is caused by the lowered detrusor pressure. An increase in urinary flow rate caused by straining was noted when anterior urethral stricture or stress incontinence was present. The increase in urinary flow rate owing to straining was undetermined in the control group. The urethral closure pressure on the anti-stress incontinence zone increased as a result of straining at the same time and to the same degree as did the intravesical pressure. When the anti-stress incontinence zone was subjected to transurethral resection for canal formation urination became possible as a result of straining. The patients who were able to urinate with straining sometimes suffered temporary stress incontinence. The degree of straining did not determine whether the patient could urinate with straining. Therefore, it was concluded that abdominal pressure should be excluded from intravesical pressure in performing several urodynamic studies on the lower urinary tract, such as pressure flow studies, and that it is important to have a sufficient canal formation in the anti-stress incontinence zone when urination with straining is expected when performing an operation on patients with urethral obstruction in the anti-stress incontinence zone.

Determine correlation between complications and stage of the disease and their impact on quality of life in patients with different types of ileal urinary derivation after radical cystectomy, and upon estimation of acquired results, to suggest the most acceptable type of urinary diversion. In five year period a prospective clinical study was performed on 106 patients, to whom a radical cystectomy was performed due to bladder cancer. Patients were divided into two groups, 66 patients with ileal conduit derivation and 40 patients with orthotopic derivation, whereby in each group a comparison between reflux and anti-reflux technique of orthotopic bladder was made. All patients from both groups filled the Sickness Impact Profile score six months after the operation. All patients had CT urography or Intravenous urography performed, as well as standard laboratory, vitamin B12 blood values, in order to evaluate early (ileus or subileus, wound dehiscence, bladder fistula, rupture of orthotopic bladder, urine extravazation) and late complications (VUR, urethral stricture, ureter stenosis, metabolic acidosis, mineral dis-balance, hypovitaminosis of vitamin B12, increased resorption of bone calcium, urinary infection, kidney damage, relapse of primary disease), so as disease stage and it's impact on quality of life. From gained results we observe that each category of SIP score correlates with different rate of correlation with the type of operation, group, T, N, and R grade, except work category. Average value of SIP score rises depending on the type of operation and T stage. It is notable that there is no difference in T1 stage, no matter the type of operation. So the average value of SIP score in T1 stage for conduit was 20.3, for Abol-Enein and Ghoneim 17.25 and Hautmann 18.75 respectively. Average value of SIP score in T2 stage for conduit was 31, for Abol-Enein and Ghoneim 19.1 and Hautmann 17.8. Average value of SIP score in T3 stage for conduit was 38.03, for Abol-Enein and Ghoneim 18.75 and Hautmann 19.5. SIP score for T4 was present only in patients with conduit performed and average value od SIP score was 40.42. There is a high level of correlation of late complications and psychosocial and physical dimension with their parameters, while for an independent dimension of correlation is not significant. Early complications have insignificant correlation in all categories of SIP score. Upon analyzing quality of life and morbidity, significant advantage is given to orthotopic derivations, especially Hautmann derivation with Chimney modification, unless there are no absolute contraindications for performing this type of operation. Factors which mostly influence quality of life are cancer stage, type of derivation, late complications and patient age. SIP score, as a well validated questionnaire, are applicable in this kind of research.

Sickle cell disease: renal manifestations and mechanisms

PubMed Central

Nath, Karl A.; Hebbel, Robert P.

2015-01-01

Sickle cell disease (SCD) substantially alters renal structure and function, and causes various renal syndromes and diseases. Such diverse renal outcomes reflect the uniquely complex vascular pathobiology of SCD and the propensity of red blood cells to sickle in the renal medulla because of its hypoxic, acidotic, and hyperosmolar conditions. Renal complications and involvement in sickle cell nephropathy (SCN) include altered haemodynamics, hypertrophy, assorted glomerulopathies, chronic kidney disease, acute kidney injury, impaired urinary concentrating ability, distal nephron dysfunction, haematuria, and increased risks of urinary tract infections and renal medullary carcinoma. SCN largely reflects an underlying vasculopathy characterized by cortical hyperperfusion, medullary hypoperfusion, and an increased, stress-induced vasoconstrictive response. Renal involvement is usually more severe in homozygous disease (sickle cell anaemia, HbSS) than in compound heterozygous types of SCD (for example HbSC and HbSβ+-thalassaemia), and is typically mild, albeit prevalent, in the heterozygous state (sickle cell trait, HbAS). Renal involvement contributes substantially to the diminished life expectancy of patients with SCD, accounting for 16–18% of mortality. As improved clinical care promotes survival into adulthood, SCN imposes a growing burden on both individual health and health system costs. This Review addresses the renal manifestations of SCD and focuses on their underlying mechanisms. PMID:25668001

To compare the performance of SpeediCath hydrophilic-coated catheters versus uncoated polyvinyl chloride (PVC) catheters, in traumatic spinal cord injured patients presenting with functional neurogenic bladder-sphincter disorders. A 1-year, prospective, open, parallel, comparative, randomised, multi centre study included 123 male patients, > or =16 y and injured within the last 6 months. Primary endpoints were occurrence of symptomatic urinary tract infection (UTI) and hematuria. Secondary endpoints were development of urethral strictures and convenience of use. The main hypothesis was that coated catheters cause fewer complications in terms of symptomatic UTIs and hematuria. 57 out of 123 patients completed the 12-month study. Fewer patients using the SpeediCath hydrophilic-coated catheter (64%) experienced 1 or more UTIs compared to the uncoated PVC catheter group (82%) (p = 0.02). Thus, twice as many patients in the SpeediCath group were free of UTI. There was no significant difference in the number of patients experiencing bleeding episodes (38/55 SpeediCath; 32/59 PVC) and no overall difference in the occurrence of hematuria, leukocyturia and bacteriuria. The results indicate that there is a beneficial effect regarding UTI when using hydrophilic-coated catheters.

Staphylococcus aureus urinary tract infections in children are associated with urinary tract abnormalities and vesico-ureteral reflux.

Staphylococcus aureus is an uncommon cause of pediatric urinary tract infection (UTI). Data regarding urinary tract malformations in children with S. aureus UTI is limited. The medical records of all children aged 0 to 16 years at Shaare Zedek Medical Center between 2001 and 2013 and who were diagnosed with S. aureus UTI were reviewed for demographic, clinical, and laboratory data. Patients with Escherichia coli UTIs during the same period were included as controls. S. aureus was the cause of UTI in 26 children, of whom six were bacteremic. Compared to children with E. coli UTI, children with S. aureus had higher rates of abnormal findings in ultrasound (77 vs. 22%; p < 0.001). Similarly, more patients with S. aureus UTI had abnormal voiding cystourethrogram (53 vs. 23%; p < 0.001) or vesicoureteral reflux (50 vs. 23%; p < 0.001). The median duration of hospitalization for patients with S. aureus UTI was significantly longer than for patients with E. coli UTI (8 vs. 2.3 days; p = 0.0003). S. aureus is an uncommon urinary pathogen among children. The finding of S. aureus UTI requires thorough search for urinary abnormalities.

Bone-anchored sling using the Mini Quick Anchor Plus and polypropylene mesh to treat post-radical prostatectomy incontinence: early experience.

PubMed

2012-10-01

Herein we describe our experience with a bone-anchored sling using a suture anchor and polypropylene mesh for the treatment of post-radical prostatectomy urinary incontinence. Eight patients with urinary incontinence as a result of intrinsic sphincter deficiency after radical prostatectomy were included in the analysis. The procedure involved piercing the pubic bone with a bone drill, inserting the suture anchor and fixing a soft or rigid polypropylene mesh to press firmly on the bulbar urethra. Urinary incontinence was significantly improved according to changes in the daily number of pads used at 1, 3 and 6 months postoperatively in comparison with preoperatively. However, no meaningful improvement at 6 months postoperatively was seen with the soft mesh. Complications included perineal pain in four cases, but pain control was achieved using non-steroidal anti-inflammatory drugs. The bone-anchored sling with a suture anchor and polypropylene mesh appears to be safe and effective for the treatment of post-radical prostatectomy urinary incontinence. Soft mesh appears inappropriate as material for the bone-anchored sling because of the progressive likelihood of worsened urinary incontinence. © 2012 The Japanese Urological Association.

[Mechanisms of urinary tract sterility maintenance].

PubMed

Okrągła, Emilia; Szychowska, Katarzyna; Wolska, Lidia

2014-06-02

Physiologically, urine and the urinary tract are maintained sterile because of physical and chemical properties of urine and the innate immune system's action. The urinary tract is constantly exposed to the invasion of microorganisms from the exterior environment, also because of the anatomical placement of the urethra, in the vicinity of the rectum. Particularly vulnerable to urinary tract infections (UTI) are women (an additional risk factor is pregnancy), but also the elderly and children. The main pathogens causing UTI are bacteria; in 70-95% of cases it is the bacterium Escherichia coli. Infections caused by viruses and fungi are less common and are associated with decreased immunity, pharmacotherapy, or some diseases. Bacteria have evolved a number of factors that facilitate the colonization of the urinary tract: the cover and cell membrane antigens O and K1, lipopolysaccharide (LPS), fimbriae, pile and cilia. On the other hand, the human organism has evolved mechanisms to hinder colonization of the urinary tract: mechanisms arising from the anatomical structure of the urinary tract, the physicochemical properties of the urine and the activity of the innate immune system, also known as non-specific, which isolates and destroys pathogens using immunological processes, and the mechanisms for release of antimicrobial substances such as Tamm-Horsfall protein, mucopolysaccharides, immunoglobulins IgA and IgG, lactoferrin, lipocalin, neutrophils, cytokines and antimicrobial peptides. This review aims to analyze the state of knowledge on the mechanisms to maintain the sterility of the urinary tract used by the human organism and bacterial virulence factors to facilitate the colonization of the urinary tract.
