Abstract Hematuria resulting from urethral traumatic catheter insertion and removal is often encountered. Usually, hematuria resolves with conservative measures. We report a case of traumatic Foley removal leading to intermittent life-threatening hematuria resulting in blood loss anemia requiring multiple transfusions and multiple episodes of hypotension requiring pressors. A pelvic angiogram revealed a pseudoaneurysm of the left pudendal artery, which was treated with microcoil embolization leading to resolution of bleeding. PMID:27579388

Hematuria is defined as an abnormal number of red blood cells in urine. Even a tiny amount of blood (1 mL in 1000 mL of urine) is sufficient to make urine appear pink or red. In the pediatric population, the majority of etiologies are benign and often asymptomatic. However, hematuria may also be a sign of renal pathology, local infection, or systemic disease. Hematuria can be differentiated into 2 categories: macroscopic hematuria (visible to the naked eye) and microscopic hematuria (> 5 red blood cells/high-powered field on urinalysis). This review will outline the current literature regarding evaluation and management of pediatric patients who present to the emergency department with hematuria. Obtaining a thorough history and the appropriate diagnostic tests will be discussed in depth.

The evaluation of patients with ureteral calculi in the emergency department has historically included urinalysis (UA) and intravenous pyelograms (IVP). This retrospective study was done to determine if a statistically significant relationship existed between the degree of calculus-related ureteral obstruction, proven by IVP, and the presence or absence of microscopic hematuria. Urine red blood cells were recorded as less than 3 rbc/hpf (negative) or greater than or equal to 3 rbc/hpf (positive). IVPs were recorded as nonsevere or severe. IVP criteria were based on the presence or absence of extravasation, greater than 2-hour ureteral filling times, and a numerical scoring system of 1 to 4 for ureteral or calyceal dilatation and nephrogenic effect. Eighty-nine men (72%) had non-severe obstructions and 34 (28%) had severe obstructions. Twenty-five women (68%) had nonsevere obstructions and 12 (32%) had severe obstructions. Of the 28 patients with normal UAs, 11 had severe ureteral obstructions and 17 had nonsevere ureteral obstructions. There were no statistically significant differences between the presence or absence of significant microscopic hematuria and the presence or absence of severe ureteral obstruction. Microscopic hematuria is neither sensitive nor specific in determining the degree of calculus-related ureteral obstruction.

2013-07-01

Intractable hematuria is a common and severe complication in patients with inoperable bladder carcinoma. The aim was to provide an overview of therapeutic options for such cases, and analyze their effectiveness and risk profile, so a systematic literature search of peer-reviewed papers published up to September 2012 was carried out. Various options are available to treat hematuria in patients with inoperable bladder cancer; these include orally administered epsilon-aminocaproic acid, intravesical formalin, alum or prostaglandin irrigation, hydrostatic pressure, urinary diversion, radiotherapy, embolization and intraarterial mitoxantrone perfusion. These treatment options are associated with different prospects of success, risks and side-effects. Well-designed and large studies comparing options are completely lacking. Despite various treatment options, management of intractable hematuria in patients with inoperable bladder cancer remains a challenge, and most of the reported methods should be seen as experimental. Interventional radiology and alum instillation seem to be suitable alternative options for patients who, after critical consideration, cannot be treated by irrigation, transurethral resection or palliative cystectomy. © 2013 The Japanese Urological Association.

Vesical schistosomiasis with terminal hematuria in sub-Saharan patients.

To know the characteristics of vesical schistosomiasis caused by schistosoma hematobium in immigrant patients. The retrospective study of 41 cases microbiologically diagnosed in our hospital over the last 16 years is presented. Data was collected on origin, age, presentation form, diagnostic tests and treatment. All were African patients whose ages ranged from 4 to 32 years and who had terminal macroscopic hematuria. Most of the patients (85%) were men. In all of the cases, diagnosis was by a urinary microbiological study and in one case, cystoscopy with a biopsy of a typical vesical lesion. Terminal hematuria is the most representative clinical sign. They were treated with praziquantel. The epidemiology and intermittent terminal hematuria in African patients should lead to the suspicion of vesical schistosomiasis as the first diagnostic option. Urinary microbiological study is a rapid, non-invasive, test with high diagnostic yield that would avoid performing invasive studies. Its simple treatment assures high level of compliance and consequent efficacy. Copyright © 2013 AEU. Published by Elsevier Espana. All rights reserved.

We report the results of a multicenter study of arterial, corticomedullary, nephrographic and excretory phase helical computerized tomography (CT) for detecting and characterizing abnormalities causing asymptomatic microscopic hematuria. We evaluated 350 consecutive patients, including 216 men and 134 women 23 to 88 years old, with asymptomatic microscopic hematuria of undetermined cause at 4 medical centers. Patients with known urological pathology were excluded from study. We performed 4 helical CT sequences, including pre-enhancement phase imaging from kidney to symphysis pubis, arterial phase imaging of the kidney and lower pelvis, corticomedullary nephrographic phase imaging of the kidney and lower pelvis, and excretory phase imaging from kidney to symphysis pubis with 2 to 5 mm. collimation and 1 to 1.5 pitch. Of 171 proved lesions 158 were correctly diagnosed. There were 10 false-positive and 13 false-negative diagnoses, indicating 0.9239 sensitivity, 0.9441 specificity, 0.9404 positive and 0.9285 negative predictive values, (p <0.001). All cases of congenital renal lesions, calculous disease, ureteral lesion and neoplastic lesion of the bladder were correctly diagnosed, as were 40 of 41 inflammatory renal, 21 of 23 renal masses and 13 of 16 inflammatory bladder lesions. In 27 patients with renal calculi the study was limited to pre-enhancement spiral CT. A positive diagnosis rate of 45.1% (158 of 350 cases) for the causes of heretofore refractory cases of hematuria with high sensitivity and specificity attest to the effectiveness of our hematuria CT protocol and support its use.

A distressing complication for patients and families, gross hematuria at the end of life challenges hospice and palliative care clinicians to utilize skills in medical and nursing management, communication and clarification of patient goals, and relief of symptom burden. Massive hemorrhage in the genitourinary tract can radically alter the terminal trajectory for patients and necessitate intensive interventions aimed at promoting comfort. Here, a case of gross hematuria in an adult hospice patient serves to broaching decision-making challenges and management strategies. PMID:24826082

1996-04-01

We developed a new technique to determine the laterality of microscopic hematuria by means of gas cystoscopy. An originally designed catheter system consisted of two catheters. On the tip of an inner catheter, a urine dipstick for blood was attached, with a cap on the tip of an outer catheter to keep the dipstick dry. In order to react a dipstick with the urine coming out from a ureteral orifice in the bladder, CO2 was insufflated into the bladder through a cystoscope (gas cystoscopy). The laterality of microscopic hematuria was determined in the bladder, based on the color reaction on the dipstick. This technique was performed successfully in 14 (88%) of 16 cases with microscopic hematuria. The laterality of microscopic hematuria was determined to be ipsilateral in 6 patients, which coincided with the side of a urological upper urinary tract disorder. In contract, bilateral microscopic hematuria was confirmed in 8 patients with glomerular disorders. The diagnostic process in patients with microscopic hematuria remains unsolved for urologists and nephrologists. This technique may provide a new approach in diagnosing microscopic hematuria.

Hematuria as a sign of aorto-caval fistula.

An aorto-caval fistula is a rare complication of an abdominal aortic aneurysm (AAA). Typical features, including congestive heart failure and a loud abdominal bruit, may be present and allow prompt diagnosis, but not infrequently they are absent or overlooked and the diagnosis not made preoperatively. Four patients with an AAA and an aorto-caval fistula are described, each of whom presented with hematuria. We believe the presence of hematuria in a patient with a symptomatic AAA should suggest the diagnosis of an aorto-caval fistula. A correct preoperative diagnosis may contribute to better planning of the operative procedure, reduced blood loss, and avoidance of possible pulmonary embolization. Images Fig. 1a. Fig. 1b. Fig. 2a.

Congenital arteriovenous fistulas are an exceptional clinical feature. Although they are frequently asymptomatic, their presentation as severe hematuria pose an excellent diagnostic exercise and often immediate therapeutic action. We report the case of a 75-year-old female patient presenting with severe hematuria producing anaemia, high blood pressure and congestive heart failure. Image tests revealed right ureteral-hydronephrosis with bladder blockage by blood clots. The endoscopic study (cystoscopy and ureterorenoscopy) alerted about the origin of the hematuria from the right kidney, finally requiring nephrectomy as definitive treatment. Pathology revealed the presence of a round formation with multiple vascular channels, arterial and venous, in the pyelocalicial submucosa, with focal epithelial erosion, compatible with congenital arteriovenous fistula. We review the diagnostic and therapeutic features in the literature. Renal congenital arteriovenous fistulas represent a diagnostic dilemma. They may present asymptomatic or condition clinical features derived from the shunt and high cardiac output (hypertensive cardiopathy and congestive heart failure) or from the erosion and acute hemorrhage into the urinary tract (severe renal hematuria). Treatment should be conservative with embolization or supraselective sclerosis. Nevertheless, in cases of big fistulas, post embolization revascularization, or hemodynamic instability nephrectomy is an excellent option.

Macroscopic hematuria caused by congenital portosystemic shunt and concomitant nutcracker syndrome.

Nutcracker syndrome (NCS) is an uncommon vascular abnormality that causes a variety of symptoms that range from asymptomatic microscopic hematuria to severe pelvic congestion. Congenital portosystemic shunt (CPSS) is an extremely rare anomaly that causes serious complications. Many cases of NCS and CPSS that have presented separately have been reported, but no cases of concomitant NCS and CPSS have been reported. We present a case of intermittent macroscopic hematuria in a patient with both NCS and CPSS. We diagnosed NCS on pressure gradient between the left renal vein (LRV) and the inferior vena cava. The presence of CPSS, which emerged from the LRV and connected to the extrahepatic portal vein, was confirmed on computed tomography. The interaction between NCS and CPSS resulted in mild intermittent macroscopic hematuria only, rather than the more common symptoms that occur when NCS or CPSS present separately. © 2015 Japan Pediatric Society.

Objective To characterize rates of hematuria-related complications among patients taking antithrombotic medications. Design, Setting, and Participants Population-based, retrospective cohort study including all citizens in Ontario, Canada, aged 66 years and older between 2002 and 2014. The final follow-up date was December 31, 2014. Exposures Receipt of an oral anticoagulant or antiplatelet medication. Main Outcomes and Measures Hematuria-related complications, defined as emergency department visit, hospitalization, or a urologic procedure to investigate or manage gross hematuria. Results Among 2 518 064 patients, 808 897 (mean [SD] age, 72.1 [6.8] years; 428 531 [53%] women) received at least 1 prescription for an antithrombotic agent over the study period. Over a median follow-up of 7.3 years, the rates of hematuria-related complications were 123.95 events per 1000 person-years among patients actively exposed to antithrombotic agents vs 80.17 events per 1000 person-years among patients not exposed to these drugs (difference, 43.8; 95% CI, 43.0-44.6; P < .001, and incidence rate ratio [IRR], 1.44; 95% CI, 1.42-1.46). The rates of complications among exposed vs unexposed patients (80.17 events/1000 person-years) were 105.78 for urologic procedures (difference, 33.5; 95% CI, 32.8-34.3; P < .001, and IRR, 1.37; 95% CI, 1.36-1.39), 11.12 for hospitalizations (difference, 5.7; 95% CI, 5.5-5.9; P < .001, and IRR, 2.03; 95% CI, 2.00-2.06), and 7.05 for emergency department visits (difference, 4.5; 95% CI, 4.3-4.7; P < .001, and IRR, 2.80; 95% CI, 2.74-2.86). Compared with patients who were unexposed to thrombotic agents, the rates of hematuria-related complications were 191.61 events per 1000 person-years (difference, 117.3; 95% CI, 112.8-121.8) for those exposed to both an anticoagulant and antiplatelet agent (IRR, 10.48; 95% CI, 8.16-13.45), 140

CASE DESCRIPTION A 6-year-old spayed female Great Pyrenees (dog 1) and a 2-year-old spayed female German Shepherd Dog (dog 2) were evaluated because of gross hematuria of 5 and 2 months' duration, respectively. CLINICAL FINDINGS In both dogs, coagulation times were within reference limits, results of aerobic bacterial culture of urine samples were negative, echogenic debris could be seen within the urinary bladder ultrasonographically, and hematuric urine could be seen exiting the right ureterovesicular junction, with grossly normal urine exiting the left ureterovesicular junction, during cystoscopy. A diagnosis of idiopathic renal hematuria was made in both dogs. TREATMENT AND OUTCOME Both dogs underwent retrograde ureteropyelography, unilateral povidone iodine sclerotherapy, and ureteral stent placement. The right ureter was occluded with a ureteropelvic junction balloon catheter, and a 5% povidone iodine solution was infused into the renal pelvis 3 times. A double-pigtail ureteral stent was then placed. Both dogs recovered without complications, with cessation of gross hematuria within 12 hours. Cystoscopic removal of the ureteral stent was performed in dog 1 after 4 months; at that time, the urine sediment contained 5 to 10 RBCs/hpf. In dog 2, urine sediment contained 50 to 75 RBCs/hpf 2 weeks after sclerotherapy, with continued resolution of gross hematuria 8 weeks after sclerotherapy. The owners declined removal of the stent in dog 2. CLINICAL RELEVANCE Findings suggested that povidone iodine sclerotherapy may be an effective renal-sparing treatment for idiopathic renal hematuria in dogs. Further evaluation with longer follow-up times is warranted.

We report a case of a young man with a history of kidney stones. Occurrence of gross hematuria several months after the extracorporeal shock wave, lithotripsy (ESWL) treatment lead to hospitalization. By ultrasound and abdominal CT scan, the urologist could exclude post-renal causes of the gross hematuria and acute renal failure. After transfer to a department of nephrology hemodialysis was started, an immediate kidney biopsy was performed and prednisolone was administered on the same day. The kidney biopsy revealed an anti-glomerular basement membrane (GBM) disease. The renal function did not recover and the patient remained on hemodialysis. In the literature it has been hypothesized that ESWL-treated patients are prone to develop anti-GBM disease by liberation of glomerular basement antigen through the ESWL high energy shock waves. An additional hypothesis considering the higher susceptibility for anti-GBM disease among certain HLA-tissue types is discussed with regard to our case. Unfortunately, the prolonged track to diagnosis and delayed immunosuppressive treatment could not prevent poor clinical outcome. Although anti-GBM disease is a rather rare disease, it should be included as a differential diagnosis for hematuria--especially months after ESWL treatment. Otherwise early diagnosis may be missed and as in our patient immunosuppressive treatment will remain unsuccessful to recover renal function.

Exploratory laparotomy was performed on a dog suspected of having idiopathic renal hematuria. Two catheters were inserted into the bilateral ureters, and hematuria from the left kidney was confirmed. The blood flow was occluded in the ventral and dorsal rami of the left renal artery in order to localize the site of hemorrhage. As hematuria disappeared when the dorsal ramus was occluded, the site of renal hematuria was localized to the area dominated by the dorsal ramus of the renal artery. As a result of ligating the dorsal ramus of the left renal artery in this dog, renal hematuria subsided, and the dog has shown a favorable course, to date, one year after surgery.

Purpose: To assess the macroscopic hematuria rates within a single-institution randomized phase 3 trial comparing dose-escalated, conventionally fractionated radiation therapy (CFRT) and moderately hypofractionated radiation therapy (MHRT) for localized prostate cancer. Methods and Materials: Patients with intermediate- to high-risk localized prostate cancer were treated with conformal RT and short-course androgen deprivation. Both the prostate and the entire seminal vesicles were treated to 80 Gy in 40 fractions over 8 weeks (CFRT) or 62 Gy in 20 fractions over 5 weeks (MHRT). The endpoint of the present study was the development of any episode or grade of macroscopic hematuria. The median follow-up period was 93 monthsmore » (range 6-143). Results: Macroscopic hematuria was reported by 25 of 168 patients (14.9%). The actuarial estimate of hematuria at 8 years was 17.0% (95% confidence interval [CI] 10.7%-23.3%). The number of patients with hematuria was 6 and 19 in the CFRT and MHRT arms, respectively, for an actuarial 8-year estimate of 9.7% and 24.3%, respectively (hazard ratio 3.468, 95% CI 1.385-8.684; P=.008). Overall, 8 of 25 patients were found to have biopsy-proven urothelial carcinoma (3 in the CFRT arm and 5 in the MHRT arm; P=.27). Thus, the 8-year actuarial incidence of macroscopic hematuria (after censoring urothelial cancer–related episodes) was 4.1% and 18.2% after CFRT and MHRT, respectively (hazard ratio 4.961, 95% CI 1.426-17.263; P=.012). The results were confirmed by multivariate analysis after accounting for several patient-, treatment-, and tumor-related covariates. Conclusions: MHRT was associated with a statistically significant increased risk of macroscopic hematuria compared with CFRT.« less

Although hematuria (blood in urine) is the most common symptom of bladder cancer, 70-98% of hematuria cases are benign. These hematuria patients unnecessarily undergo costly, invasive, and expensive evaluation for bladder cancer. Therefore, there remains a need for noninvasive office-based tests that can rapidly and reliably rule out bladder cancer in patients undergoing hematuria evaluation. Herein, a clinical assay for matrix metalloproteinases ("Ammps") is presented, which generates a visual signal based on the collagenase activity (in urine of patients) on the Ammps substrates. Ammps substrates are generated by crosslinking gelatin with Fe(II) chelated alginate nanoparticles, which precipitate in urine samples. The cleavage of gelatin-conjugated alginate (Fe(II)) nanoparticles by collagenases generates free-floating alginate (Fe(II)) nanoparticles that participate in Fenton's reaction to generate a visual signal. In a pilot study of 88 patients, Ammps had 100% sensitivity, 85% specificity, and a negative predictive value (NPV) of 100% for diagnosing bladder cancer. This high NPV can be useful in ruling out bladder cancer in patients referred for hematuria evaluation. © 2017 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

We describe the case of a 27-year-old woman with a history of sickle cell trait (SCT) who presented with several months of hematuria and was found to have nutcracker syndrome (NCS). While SCT is a common cause of hematuria resulting from renal papillary necrosis, our patient had concomitant abdominal pain and anemia, prompting further evaluation and the subsequent diagnosis of NCS. Interestingly, the anoxia in the left renal vein from NCS predisposes patients with SCT to sickling. Our case highlights key clinical features of both NCS and SCT and the relationship between the two disease processes.

Arsenic (As) exposure has been associated with both urologic malignancy and renal dysfunction; however, its association with hematuria is unknown. We evaluated the association between drinking water As exposure and hematuria in 7843 men enrolled in the Health Effects of Arsenic Longitudinal Study (HEALS). Cross-sectional analysis of baseline data was conducted with As exposure assessed in both well water and urinary As measurements, while hematuria was measured using urine dipstick. Prospective analyses with Cox proportional regression models were based on urinary As and dipstick measurements obtained biannually since baseline up to six years. At baseline, urinary As was significantly relatedmore » to prevalence of hematuria (P-trend < 0.01), with increasing quintiles of exposure corresponding with respective prevalence odds ratios of 1.00 (reference), 1.29 (95% CI: 1.04–1.59), 1.41 (95% CI: 1.15–1.74), 1.46 (95% CI: 1.19–1.79), and 1.56 (95% CI: 1.27–1.91). Compared to those with relatively little absolute urinary As change during follow-up (− 10.40 to 41.17 μg/l), hazard ratios for hematuria were 0.99 (95% CI: 0.80–1.22) and 0.80 (95% CI: 0.65–0.99) for those whose urinary As decreased by > 47.49 μg/l and 10.87 to 47.49 μg/l since last visit, respectively, and 1.17 (95% CI: 0.94–1.45) and 1.36 (95% CI: 1.10–1.66) for those with between-visit increases of 10.40 to 41.17 μg/l and > 41.17 μg/l, respectively. These data indicate a positive association of As exposure with both prevalence and incidence of dipstick hematuria. This exposure effect appears modifiable by relatively short-term changes in drinking water As. - Highlights: • Hematuria is the most common symptom of urinary tract disease. • Arsenic exposure is associated with renal dysfunction and urologic malignancy. • Water arsenic was positively associated with prevalence and incidence of hematuria. • Reduction in exposure lowered hematuria risk especially in low

Gross, intractable hematuria is rare in children. Although the role of epsilon aminocaproic acid in the management of refractory hematuria is well established in the adult population, few data exist about its use in children for this indication. We present our initial experience with epsilon aminocaproic acid for the treatment of intractable hematuria after more conservative measures failed, and propose an algorithm for administration of epsilon aminocaproic acid in children. We reviewed the charts of all patients treated with epsilon aminocaproic acid for intractable gross hematuria at our institution during a period of 36 months. All patients underwent hematological evaluation and any underlying bleeding dyscrasias were addressed. All patients also underwent renal and bladder ultrasound, retrograde pyelogram and ureteroscopy. Demographic information, medical and surgical histories, and epsilon aminocaproic acid dosing and outcomes were recorded. Three boys and 1 girl 11 to 17 years old were treated with epsilon aminocaproic acid. Three patients had sickle trait (1 with nutcracker phenomenon) and 1 had hemophilia A. Three patients required packed red blood cell transfusions to maintain hematocrit. Three renal angiograms were performed, all of which were nondiagnostic. Duration of hematuria ranged from 1 to 52 weeks before administration of epsilon aminocaproic acid. Endoscopic evaluation demonstrated hematuria localized to 1 ureteral orifice in all 4 patients. All patients received 100 mg/kg epsilon aminocaproic acid orally every 6 hours, which uniformly led to cessation of hematuria. Epsilon aminocaproic acid is useful for the management of gross refractory hematuria when more conservative measures fail. Because of its potential side effects, it should be used cautiously. 2010 American Urological Association Education and Research, Inc. Published by Elsevier Inc. All rights reserved.

Guidelines recommend ruling out malignancy in men and women presenting with hematuria. This study sought to determine the difference in timing from presentation with hematuria to diagnosis of bladder cancer in women versus men. This is a retrospective population-based study examining the timing from presentation with hematuria to diagnosis of bladder cancer, based on data from the MarketScan databases, which include enrollees of more than 100 health insurance plans of approximately 40 large US employers from 2004 through 2010. All study patients presented with hematuria and were subsequently diagnosed with bladder cancer. The primary outcome measure was number of days between initial presentation with hematuria and diagnosis of bladder cancer by sex. A total of 5416 men and 2233 women met inclusion criteria. Mean days from initial hematuria claim to bladder cancer claim was significantly longer in women (85.4 versus 73.6 days, P < .001), and the proportion of women with >6 month delay in bladder cancer diagnosis was significantly higher (17.3% versus 14.1%, P < .001). Women were more likely to be diagnosed with urinary tract infection (odds ratio = 2.32, 95% confidence interval = 2.07-2.59) and less likely to undergo abdominal or pelvic imaging (odds ratio = 0.80, 95% confidence interval = 0.71-0.89). Both men and women experience significant delays between presentation with hematuria and diagnosis of bladder cancer, with longer delays for women. This may be partly responsible for the sex-based discrepancy in outcomes associated with bladder cancer. © 2013 American Cancer Society.

To estimate the prevalence of gross hematuria and urinary retention among men in Sierra Leone and report on barriers to care and associated disability. Gross hematuria and urinary retention are classic urologic complaints that require medical attention for significant underlying pathology, but their burden has not been quantified in a developing country. A cluster randomized, cross-sectional household survey was administered in Sierra Leone using the Surgeons OverSeas Assessment of Surgical need tool as a verbal head-to-toe examination. A total of 2 respondents in each of 25 households in 75 clusters were surveyed to assess surgical needs. Data on questions related to blood from the penis and the inability to urinate for men>12 years were included in the present analysis to determine the period and point prevalence of hematuria and urinary retention. From 3645 total respondents, 1054 (28.9%) were men>12 years included in the analysis. Period and point prevalence of gross hematuria were 21.8 per 1000 (95% confidence interval [CI] 13.0-30.7) and 12.3 per 1000 (95% CI 5.7-19.0), respectively, and for urinary retention, they were 19.9 per 1000 (95% CI 11.5-28.4) and 4.7 per 1000 (95% CI 0.5-8.9), respectively. Lack of financial resources was the major barrier to care. Disability assessment showed 19.1% were not able to work as a result of urinary retention, and 34.8% felt ashamed of their gross hematuria. The results provide a prevalence estimate of gross hematuria and urinary retention for men in Sierra Leone. Accessible medical and surgical care will be critical for early intervention and management. Copyright © 2014 Elsevier Inc. All rights reserved.

Hematuria is often a significant symptom in patients with disseminated renal cell carcinoma. We present a case in which the minimally invasive procedure of radio-frequency ablation was used in a patient with serious hematuria. The procedure was completely successful and there were no complications. In our opinion it may be recommended in such a situation.

Should the presence of a culture positive urinary tract infection exclude patients from rapid evaluation hematuria protocols?

Vasdev, Nikhil; Thorpe, Andrew C

Current rapid evaluation protocols for patients with hematuria tend to exclude those with urinary tract infection since this is assumed to be evidence of a benign treatable cause. The likelihood of a urinary tract cancer in such patients is, however, uncertain, and we have therefore analyzed a prospective hematuria clinic database to determine risk. A total of 1,740 patients were enrolled prospectively in this study at our unit's one stop fast track hematuria clinic between April 2003 and March 2006. Evaluation of patients consisted of basic demographics, history and examination, urinalysis, urine culture, urine cytology, and serum creatinine. All patients then underwent a renal ultrasound, intravenous urogram, and cystoscopy. A total of 1,067 males and 673 females with a mean (range) age of 60.8 (16-96) years were included in the study. One hundred sixty-one patients had a positive mid-stream urine (MSU) on a specimen collected at the hematuria clinic. Amongst this group 20% (32) patients had a urologic malignancy diagnosed, of whom 12% (4) had metastatic disease at presentation. Only 1% (3) of patients had a urologic malignancy with a previous history of a treated urinary tract infection (UTI) and negative MSU at the clinic. The risk of urologic malignancy was 24% (303) in the remaining 1,249 patients with no history of a UTI prior to presentation and a negative MSU on a specimen collected at the one stop fast track hematuria clinic. Despite selection bias inherent in this analysis, it appears that the presence of UTI does not decrease the likelihood of having a urologic malignancy diagnosed. Hence, there is no indication to delay prompt evaluation in patients with hematuria and a positive urine culture collected at the hematuria clinic. Copyright © 2013 Elsevier Inc.

Computed tomography urogram (CTU) is recommended when investigating patients with hematuria. We determine the incidence of urinary tract cancer and compare the diagnostic accuracy of CTU and renal and bladder ultrasound (RBUS) at identifying urinary tract cancer. The DETECT I study (clinicaltrials.gov NCT02676180) is a prospective observational study recruiting patients ≥18 years following a presentation of macroscopic or microscopic haematuria at 40 hospitals. All patients had cystoscopy and upper tract imaging (CTU, RBUS or both). 3,556 patients with a median age of 68 years were recruited, of which 2166 had RBUS and 1692 had CTU in addition to cystoscopy. The incidence of bladder, renal and upper tract urothelial cancer (UTUC) were 11.0%, 1.4% and 0.8% respectively in macroscopic hematuria patients. Patients with microscopic hematuria had a 2.7%, 0.4% and 0% incidence of bladder, renal and UTUC respectively. The sensitivity and negative predictive value (NPV) of RBUS for the detection of renal cancer was 85.7% and 99.9% respectively but 14.3% and 99.7% for the detection of UTUC. RBUS was poor at identifying renal calculi. Sensitivity of RBUS was lower than CTU for the detection of bladder cancer (both <85%). Cystoscopy has a specificity and PPV of 98.3% and 83.9% respectively. CTU can be safely replaced with RBUS in patients with microscopic hematuria. The incidence of UTUC is 0.8% in patients with macroscopic hematuria and CTU is recommended. Patients with suspected renal calculi will require non-contrast renal tract CT. Imaging cannot replace cystoscopy to diagnose bladder cancer. Copyright © 2018 American Urological Association Education and Research, Inc. Published by Elsevier Inc. All rights reserved.

Endovascular Management of Ureteroarterial Fistula: A Rare Potentially Life Threatening Cause of Hematuria

2014-01-01

Ureteroarterial fistula is a rare, potentially life-threatening cause of hematuria characterized by an abnormal channel between a ureter and artery. The rarity of this condition, complexity of predisposing risk factors and intermittence of symptoms may delay or obscure its diagnosis. With a high index of suspicion and careful angiographic evaluation, embarking on this condition is not only possible but sets the stage for curative intervention. We report a case of a ureteroarterial fistula presenting with intermittent hematuria, successfully diagnosed at angiography and managed with endovascular stent graft placement. PMID:25426238

Arteriovesical fistulas are extremely rare. Only eleven cases were previously reported in the literature. They can occur iatrogenically, traumatically or spontaneously. We report an unusual case of a 62-year-old woman with arteriovesical fistula that developed fatal hematuria after transurethral electrocoagulation. Computed tomography (CT) and selective angiography revealed a pseudoaneurysm of the right superior vesical artery with arteriovesical fistula formation, which was managed by transarterial embolization. Contrast enhanced CT or CT angiography should be performed when a pulsatile hemorrhage is revealed during cystoscopy. Therapeutic vesical arterial embolization should be considered as a safe and effective procedure for arteriovesical fistulas. Transurethral electrocoagulation may cause severe hematuria for pulsatile bladder bleeding in patients with pelvic vascular malformation.

To report a case of bladder injury with hematuria and urinary retention after transvaginal oocyte aspiration. Case report. Emergency room in a university medical center. A 28-year-old woman presented with urinary retention and suprapubic pain 8 hours after oocyte aspiration. Foley catheter, intravenous fluid bolus, bladder irrigation, and computed tomography with postvoid films that showed a blood clot in the bladder. Patient was discharged home with antibiotics and catheter in place. Clinical follow-up. Patient passed voiding trial 4 days later and was artificially inseminated. No further hematuria or voiding problems were reported, and she had a successful pregnancy. Patients who elect to undergo oocyte aspiration should be warned about the possibility of bladder injury because of the close proximity of the ovaries to the bladder, and physicians should have an appropriate treatment plan.

Arsenic (As) exposure has been associated with both urologic malignancy and renal dysfunction; however, its association with hematuria is unknown. We evaluated the association between drinking water As exposure and hematuria in 7843 men enrolled in the Health Effects of Arsenic Longitudinal Study (HEALS). Cross-sectional analysis of baseline data was conducted with As exposure assessed in both well water and urinary As measurements, while hematuria was measured using urine dipstick. Prospective analyses with Cox proportional regression models were based on urinary As and dipstick measurements obtained biannually since baseline up to six years. At baseline, urinary As was significantly related to prevalence of hematuria (P-trend<0.01), with increasing quintiles of exposure corresponding with respective prevalence odds ratios of 1.00 (reference), 1.29 (95% CI: 1.04-1.59), 1.41 (95% CI: 1.15-1.74), 1.46 (95% CI: 1.19-1.79), and 1.56 (95% CI: 1.27-1.91). Compared to those with relatively little absolute urinary As change during follow-up (-10.40 to 41.17 μg/l), hazard ratios for hematuria were 0.99 (95% CI: 0.80-1.22) and 0.80 (95% CI: 0.65-0.99) for those whose urinary As decreased by >47.49 μg/l and 10.87 to 47.49 μg/l since last visit, respectively, and 1.17 (95% CI: 0.94-1.45) and 1.36 (95% CI: 1.10-1.66) for those with between-visit increases of 10.40 to 41.17 μg/l and >41.17 μg/l, respectively. These data indicate a positive association of As exposure with both prevalence and incidence of dipstick hematuria. This exposure effect appears modifiable by relatively short-term changes in drinking water As. Copyright © 2014 Elsevier Inc. All rights reserved.

To study the usefulness and safety of ureteropyeloscopy in the diagnosis of upper tract hematuria of unknown etiology by standard diagnostic methods. Fifteen patients with upper tract hematuria of unknown etiology were the subjects of the present study. Prior to ureteropyeloscopy, they underwent standard diagnostic methods, including cystourethroscopy, excretory urography and computed tomography scan. The upper tract (ureter, renal pelvis and calyces) was inspected systematically with a flexible ureteropyeloscope under epidural anesthesia. A biopsy specimen was obtained when neoplasm of a suspicious lesion was seen. Bleeding and hemangiomatous lesions were fulgurated at the time of ureteropyeloscopy. Unilateral gross hematuria was seen in 12 patients. Imaging studies revealed a filling defect in four patients, ureteral stenosis in one patient and nutcracker phenomenon in one patient. Urine cytology was positive in three patients and suspicious in four patients. Results of ureteropyeloscopy were papillary tumor in three patients, whitish encrustation in one patient, redness of the renal pelvis in one patient, bleeding from the renal calyx in two patients, hemangiomatous lesion in one patient, ureteral stenosis in two patients and no abnormalities in five patients. Biopsies were performed in five patients. The pathology results were transitional cell carcinoma in four patients and no abnormality in one patient. Although a ureteral stent catheter was placed in one patient, no serious complications were encountered during or after the procedures. Ureteropyeloscopy was useful and relatively safe. This endoscopic examination can differentiate insignificant lesions from significant lesions by visual inspection of the lesions, in addition, pathological diagnosis by biopsy specimen can also be performed if deemed necessary. Ureteropyeloscopy is recommended in the diagnosis of upper tract hematuria of unknown etiology.

Castleman's disease is a rare benign lymphoproliferative disorder, characterized by benign growths of the lymph node tissue. It is associated with a number of malignancies, including Kaposi sarcoma, non-Hodgkin's and Hodgkins lymphoma, and POEMS syndrome. This report describes the case of a 38 year old gentleman, presenting with painless hematuria. Initial investigations, including flexible cystoscopy were unremarkable. However, subsequent imaging including CT Urogram and MR pelvis revealed multiple prevesical lesions. Histology obtained from excision biopsy revealed histological features consistent with Castleman's disease. In this report we discuss the nature, presentation and treatment modalities of this rare condition.

Familial microscopic hematuria (MH) of glomerular origin represents a heterogeneous group of monogenic conditions involving several genes, some of which remain unknown. Recent advances have increased our understanding and our ability to use molecular genetics for diagnosing such patients, enabling us to study their clinical characteristics over time. Three collagen IV genes, COL4A3, COL4A4, and COL4A5 explain the autosomal and X-linked forms of Alport syndrome (AS), and a subset of thin basement membrane nephropathy (TBMN). A number of X-linked AS patients follow a milder course reminiscent of that of patients with heterozygous COL4A3/COL4A4 mutations and TBMN, while at the same time a significant subset of patients with TBMN and familial MH progress to chronic kidney disease (CKD) or end-stage kidney disease (ESKD). A mutation in CFHR5, a member of the complement factor H family of genes that regulate complement activation, was recently shown to cause isolated C3 glomerulopathy, presenting with MH in childhood and demonstrating a significant risk for CKD/ESKD after 40 years old. Through these results molecular genetics emerges as a powerful tool for a definite diagnosis when all the above conditions enter the differential diagnosis, while in many at-risk related family members, a molecular diagnosis may obviate the need for another renal biopsy.

Objectives: To determine the prevalence of hypertension, obesity, hematuria, and proteinuria among healthy adolescents and to determine the associated risk factors. Methods: This is a cross-sectional study of 8 intermediate schools in Jeddah, Saudi Arabia between March 2015 and June 2015. Samples were selected randomly and equal proportions from each school for both genders were ensured. Both blood pressure and body mass index were measured and a brief questionnaire was filled out for the specified studied group. Urine dipstick analysis was carried out for 294 children. A second questionnaire was completed for hypertensive and obese subjects in addition to those with hematuria and proteinuria. Results: A total of 401 children (200 males) with a mean (SD) age of 13.87 (1.27) were included. Hypertension was found in 17.2% with a male to female ratio of 1.4:1. Pre-hypertension was found in 4.2% of our sample with a male to female ratio of 2.1:1. Obesity was found in 19.2% with a male to female ratio of 1.5:1. Obesity was found to be the most significant risk factor for hypertension with a related risk: 2.87, 95% and confidence interval: 1.9-4.3. For urine abnormalities, 10.2% of samples were positive for proteinuria, 17% for hematuria, and 3.1% for both. Conclusion: It was found that there is a positive correlation between the incidence of obesity and hypertension in adolescents. Hematuria and proteinuria were also found to be high. Screening and prevention programs are therefore recommended. PMID:27652364

Dipstick urine tests are used for general health screening in Japan. The effects of this screening on mortality have not been examined, especially with regard to hematuria. Subjects were those who participated in the 2008 Tokutei-Kenshin (nationwide specific health check and guidance program) in six districts in Japan. Using the national database of death certificates from 2008 to 2012, we identified subjects who might have died. We verified the candidates in collaboration with the regional National Health Insurance agency and public health nurses. Data were released to the research team supported by the Ministry of Health, Labor, and Welfare of Japan. Dipstick results of 1+ and higher were defined as hematuria (+). Hazard ratio (HR) [95% confidence interval (CI)] was calculated using the Cox proportional hazard analysis. Among 112 115 subjects, we identified that 1290 had died by the end of 2012. In hematuria (-) subjects, the crude mortality rates were 1.2% (1.8% in men, 0.7% in women), whereas in hematuria (+) subjects, they were 1.1% (2.9% in men, 0.7% in women). After adjusting for age, body mass index, estimated glomerular filtration rate, proteinuria, comorbid condition (diabetes mellitus, hypertension and dyslipidemia), past history (stroke, heart disease and kidney disease) and lifestyle (smoking, drinking, walking and exercise), the HR (95% CI) for dipstick hematuria (+) in men was 1.464 (1.147-1.846; P = 0.003), whereas that for hematuria (-) was 0.820 (0.617-1.073; P = 0.151). Dipstick hematuria is significantly associated with mortality in men among Japanese community-based screening participants.

Xp11.2 translocation tumor is a rare but aggressive form of renal cell carcinoma that predominantly occurs in children but also may be found in young adults. Because this type of cancer is diagnosed via histologic and chromosomal analysis, clinicians should consider translocation tumor in the differential diagnosis of patients with renal lesions and gross hematuria.

We investigated 2 Chinese families with dyschromatosis symmetrica hereditaria (DSH) and search for mutations in the adenosine deaminase acting on RNA1 (ADAR1) gene in these 2 pedigrees. We performed a mutation analysis of the ADAR1 gene in 2 Chinese families with DSH and reviewed all articles published regarding ADAR1 mutations reported since 2003 by using PubMed. By direct sequencing, a 2-nucleotide AG deletion, 2099-2100delAG, was found in family 1, and a C→T mutation was identified at nucleotide 1420 that changed codon 474 from arginine to a translational termination codon in family 2. Two different pathogenic mutations were identified, c.2099-2100delAG and c.1420C>T, the former being a novel mutation, and the latter previously reported in 3 other families with DSH. To date, a total of 110 mutations in the ADAR1 gene have been reported, and 10 of them were recurrent; the mutations R474X, R1083C, R1096X, and R1155W might be the DSH-related hotspots.

A Cough Deteriorating Gross Hematuria: A Clinical Sign of a Forthcoming Life-Threatening Rupture of an Intraparenchymal Aneurysm of Renal Artery (Wunderlich's Syndrome)

Macroscopic hematuria regards the 4% to 20% of all urological visits. Renal artery aneurysms (RAAs) are detected in approximately 0.01%–1% of the general population, while intraparenchymal renal artery aneurysms (IPRAAs) are even more rarely detected in less than 10% of patients with RAAs. We present a case of a 58-year-old woman that came into the emergency room (ER) complaining of a gross hematuria during the last four days. Although in the ER room the first urine sample was clear after a cough episode, a severe gross hematuria began which led to a hemodynamically unstable patient. Finally, a radical nephrectomy was performed, and an IPRAA was the final diagnosis. A cough deteriorating hematuria could be attributed to a ruptured intraparenchymal renal artery aneurysm, which even though constitutes a rare entity, it is a life-threatening medical emergency.

The study evaluates the prevalence of urogenital schistosomiasis and diagnostic performance of chemical reagent strips used for disease diagnosis in preschool-aged children (≤ 5 years) in Nigeria rural communities. Urine samples from 419 children were observed microscopically for Schistosoma haematobium and screened for hematuria using standard urine chemical reagent strips. Prevalence and intensity of infection were 9.8% and 14.4 eggs/10 ml of urine, respectively. Prevalence of infection was similar in girls (10%) and boys (9.6%) (p > 0.05). The intensity of infection was higher in boys (17.1 eggs/10 ml of urine) than in girls (12.8 eggs/10 ml of urine); however, this was not gender dependent (p > 0.05). The occurrence of hematuria was not associated with gender (p > 0.05), but was associated with prevalence of infection (p < 0.05). Infection with S. haematobium occurs early in life in the communities and although intensity of infection is low, it could have serious implications in disease transmission. Hematuria, although moderately sensitive to infection, is an important morbidity indicator of urogenital schistosomiasis in the study population.

We sought to determine whether race, gender and number of bladder cancer risk factors are significant predictors of hematuria evaluation. We used self-reported data from SCCS (Southern Community Cohort Study) linked to Medicare claims data. Evaluation of subjects diagnosed with incident hematuria was considered complete if imaging and cystoscopy were performed within 180 days of diagnosis. Exposures of interest were race, gender and risk factors for bladder cancer. Of the 1,412 patients evaluation was complete in 261 (18%). On our adjusted analyses African American patients were less likely than Caucasian patients to undergo any aspect of evaluation, including urology referral (OR 0.72, 95% CI 0.56-0.93), cystoscopy (OR 0.67, 95% CI 0.50-0.89) and imaging (OR 0.75, 95% CI 0.59-0.95). Women were less likely than men to be referred to a urologist (OR 0.59, 95% CI 0.46-0.76). Also, although all patients with 2 or 3 risk factors had 31% higher odds of urology referral (OR 1.31, 95% CI 1.02-1.69), adjusted analyses indicated that this effect was only apparent among men. Only 18% of patients with an incident hematuria diagnosis underwent complete hematuria evaluation. Gender had a substantial effect on referral to urology when controlling for socioeconomic factors but otherwise it had an unclear role on the quality of evaluation. African American patients had markedly lower rates of thorough evaluation than Caucasian patients. Number of risk factors predicted referral to urology among men but it was otherwise a poor predictor of evaluation. There is opportunity for improvement by increasing the completion of hematuria evaluations, particularly in patients at high risk and those who are vulnerable.

Abbaszadeh, Shahin; Taheri, Saeed; Nourbala, Mohammad Hossein

2009-01-01

Aim. In this study we report our experience with microhematuria and its relation with bladder tumors in Iranian women. Materials and Methods. Overall 249 women were evaluated. Microscopic hematuria was defined as three or more red blood cells per high-power field on at least two different occasions. Patients with a history of gross hematuria or coagulation disorders, having organic diseases, urinary stones, urinary tract infections, nephrological diseases, and local lesions such as urethral caruncle were excluded from the study population. Final diagnosis of malignant tumors was done with cystoscopy and biopsy specimen pathological assessment in all cases. Results. Age for the study population was 49.7 ± 11.8 years. 95 (38%) of patients were identified during routine check up and presenting symptoms in other patients were frequency, dysuria, stress urge incontinence, urge incontinence, feeling of incomplete urine emptying, and flunk pain, respectively. Finally, 7 (2.8%) of study subjects were confirmed as having bladder tumors. One of tumor cases was diagnosed 24 months after initial assessments. Patients with bladder tumor were significantly older; more frequently had diverticulum in their bladder wall (P < .05). Conclusion. Female microscopic hematuria is relevant and deserves evaluations, especially in elderly patients. Patients whose reason for microhematuria would not be diagnosed at the initial evaluations should be followed. PMID:19639044

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.

Psychogenic purpura (Gardner-Diamond syndrome) is the occurrence and spontaneous recurrence of painful ecchymosis following emotional stress and minor trauma. Although the exact mechanism of this syndrome remains unknown, apart from skin lesions, different types of hemorrhaging have been reported, such as epistaxis, gastrointestinal bleeding, and bleeding from the ear canals and eyes. We report a psychogenic purpura case that presented with hematuria in addition to skin lesions. Based on the psychiatric evaluation she was diagnosed with major depressive disorder, generalized anxiety disorder, and obsessive-compulsive disorder. Additionally, sexual pain disorder accompanied these disorders. With the help of antidepressant and supportive psychotherapy, the patient's ecchymosis and bleeding disappeared. During 8 months of follow-up the symptoms did not return. Vaginismus has not been reported in patients with psychogenic purpura. The presence of vaginismus, which is seen more frequently in eastern cultures and is thought to be related to sociocultural determinants, suggests that some cultural factors may be common to both psychogenic purpura and vaginismus. The aim of this case report was to call attention to a syndrome that is rarely seen and diagnosed, and to discuss its relationship to psychosocial factors. This syndrome should be considered in the differential diagnosis of not only ecchymotic lesions, but also various types of bleeding, including hematuria. Despite the fact that its etiology and treatment are not clearly understood, it should be noted that psychological factors play a role in this disease and therefore, psychopharmacological and psychotherapeutic approaches can be effective.

Hemoglobinuria Misidentified as Hematuria: Review of Discolored Urine and Paroxysmal Nocturnal Hemoglobinuria

PubMed Central

Veerreddy, Prashant

2013-01-01

Discolored urine is a common reason for office visits to a primary care physician and urology referral. Early differentiation of the type or cause of discolored urine is necessary for accurate diagnosis and prompt management. Paroxysmal nocturnal hemoglobinuria is a clonal disorder caused by acquired somatic mutations in the PIG-A gene on the X- chromosome of hemopoietic stem cells and leads to deficiency of surface membrane anchor proteins. The deficiency of these proteins leads to an increased risk of hemolysis of erythrocytes and structural damage of platelets, resulting in a clinical syndrome characterized by complement-mediated intravascular hemolytic anemia, bone marrow failure, and venous thrombosis. Patients with this clinical syndrome present with paroxysms of hemolysis, causing hemoglobinuria manifesting as discolored urine. This can be easily confused with other common causes of discolored urine and result in extensive urologic work-up. Three commonly confused entities of discolored urine include hematuria, hemoglobinuria, and myoglobinuria. Specific characteristics in a dipstick test or urinalysis can guide differentiation of these three causes of discolored urine. This article begins with a case summary of a woman presenting with cranberry-colored urine and a final delayed diagnosis of paryxysmal nocturnal hemoglobinuria. Her hemoglobinuria was misdiagnosed as hematuria, leading to extensive urologic work-up. The article also gives an overview of the approach to diagnosing and treating discolored urine. PMID:25512715

Cases of primary non-Hodgkin’s lymphoma of the prostate are globally rare. The present study reports a case of prostatic diffuse large B-cell lymphoma (DLBCL) with intractable hematuria in a 75-year-old male. The patient presented with difficulties in urination and gross hematuria. A prostate biopsy was performed immediately, followed by conservative treatment for bleeding. A bilateral iliac arteriography and chemoembolization were then performed as emergency procedures under local anesthesia due to significant bleeding and a sharply decreased blood pressure, indicating the failure of the conservative treatment. Consequently, the bleeding was effectively controlled. Pathological examination of the prostate biopsy confirmed the presence of a DLBCL of non-germinal center B-cell origin. Immunohistochemical examination demonstrated cluster of differentiation (CD)20(++), CD3(+), leukocyte common antigen(+++), B-cell lymphoma-2(+) and prostate-specific antigen(−) results. Due to the poor general condition and low hemoglobin levels of the patient, a low-dose Rituximab plus cyclophosphamide, doxorubicin, vincristine and prednisone (R-CHOP) chemotherapy regimen was administered. Subsequent to three courses of chemotherapy, the patient achieved complete remission. In conclusion, combining R-CHOP and bilateral selective iliac arterial chemoembolization could be a safe and effective way to treat patients with non-Hodgkin’s lymphoma of the prostate and intractable hematuria.

We report the case of a patient with heterozygous sickle cell trait presenting with massive gross hematuria. Ureteroscopy revealed bleeding from the tip of papilla of the inferior calica and allowed us to tamponade the bleeding with a balloon ureteral dilator set (Cook(R) Urology). We show the value of the endourological approach in the conservative management of these patients at high risk of recurrent hematuria.

Many patients enter the care cycle with gross or microscopic hematuria and undergo cystoscopy to rule out bladder cancer. Sensitivity of this invasive examination is limited, leaving many patients at risk for undetected cancer. To improve current clinical practice more sensitive and noninvasive screening methods should be applied. A total of 154 urine samples were collected from patients with hematuria, including 80 without and 74 with bladder cancer. DNA from cells in the urine was epigenetically profiled using 2 independent assays. Methylation specific polymerase chain reaction was performed on TWIST1. SNaPshot™ methylation analysis was done for different loci of OTX1 and ONECUT2. Additionally all samples were analyzed for mutation status of TERT (telomerase reverse transcriptase), PIK3CA, FGFR3 (fibroblast growth factor receptor 3), HRAS, KRAS and NRAS. The combination of TWIST1, ONECUT2 (2 loci) and OTX1 resulted in the best overall performing panel. Logistic regression analysis on these methylation markers, mutation status of FGFR3, TERT and HRAS, and patient age resulted in an accurate model with 97% sensitivity, 83% specificity and an AUC of 0.93 (95% CI 0.88-0.98). Internal validation led to an optimism corrected AUC of 0.92. With an estimated bladder cancer prevalence of 5% to 10% in a hematuria cohort the assay resulted in a 99.6% to 99.9% negative predictive value. Epigenetic profiling using TWIST1, ONECUT2 and OTX1 results in a high sensitivity and specificity. Accurate risk prediction might result in less extensive and invasive examination of patients at low risk, thereby reducing unnecessary patient burden and health care costs.

2011-05-01

Emphysematous cystitis is a relatively rare infectious condition of the urinary bladder. The mortality rate is high if the diagnosis is delayed or if the treatment is inadequate. We present an uncommon case of emphysematous cystitis and highlight the risk factors for this disease. An 81-year-old man with a past medical history of type 2 diabetes and a central pontine infarction presented to the Emergency Department due to gross hematuria. Computed tomography (CT) and plain radiography revealed localized gas within the bladder that was compatible with the diagnosis of emphysematous cystitis. A Foley catheter was inserted. Urine culture grew Klebsiella pneumoniae; 2 g cefotaxime daily was initiated. Subsequent plain radiography and CT scan showed regression of intraluminal gas. We recommend CT for the definitive diagnosis of emphysematous cystitis. Adequate antibiotic therapy, strict blood glucose control, adequate drainage of urine, and early goal-directed therapy for suspected sepsis are suggested to prevent the complications of emphysematous cystitis.

Local forms of the tranexamic acid have been effective in treating many haemorrhagic cases. So that the aim of the current study is to assess the effectiveness of local tranexamic acid in controlling painless hematuria in patients referred to the emergency department. This is a randomized, double-blind clinical trial study, which was conducted on 50 patients with complaints of painless lower urinary tract bleeding during June 2014 and August 2015. The patients were randomly divided into two groups of 25 people each, one group receiving tranexamic acid and the other given a placebo. During bladder irrigation, local tranexamic acid and the placebo were injected into the bladder via Foley catheter. Patients were examined over 24h in terms of the amount of normal saline serum used for irrigation, level of hemoglobin, and blood in urine. In this study it was observed that consumption of tranexamic acid significantly decreased the volume of used serum for bladder irrigation (P=0.041) and the microscopic status of urine decreased significantly in terms of the hematuria after 24h (P=0.026). However, the rate of packed cell transfusion and drop in hemoglobin levels showed no significant difference in both groups of patients (P˃0.05). The results of this study showed that tranexamic acid could significantly reduce the volume of required serum for bladder irrigation to clear urine, but it had no significant effect on the drop in serum hemoglobin levels.

2006-01-01

Radiofrequency ablation is increasingly being acknowledged as a valid treatment for renal cell carcinoma in patients in whom definitive curative resection is deemed either undesirable or unsafe. A number of published series have shown the technique to have encouraging results and relatively low complication rates. In this article, we report a case of delayed life-threatening hematuria requiring transcatheter embolization of a bleeding intrarenal artery in a patient who had undergone imaging-guided radiofrequency ablation of a 3 cm renal cell carcinoma. To our knowledge, such a complication has not been reported previously.

Dyschromatosis universalis hereditaria (DUH) is a rare heterogeneous pigmentary genodermatosis, which was first described in 1933. The genetic cause has recently been discovered by the discovery of mutations in ABCB6. Here we investigated a Chinese family with typical features of autosomal dominant DUH and 3 unrelated patients with sporadic DUH. Skin tissues were obtained from the proband, of this family and the 3 sporadic patients. Histopathological examination and immunohistochemical analysis of ABCB6 were performed. Peripheral blood DNA samples were obtained from 21 affected, 14 unaffected, 11 spouses in the family and the 3 sporadic patients. A genome-wide linkage scan for the family was carried out to localize the causative gene. Exome sequencing was performed from 3 affected and 1 unaffected in the family. Sanger sequencing of ABCB6 was further used to identify the causative gene for all samples obtained from available family members, the 3 sporadic patients and a panel of 455 ethnically-matched normal Chinese individuals. Histopathological analysis showed melanocytes in normal control's skin tissue and the hyperpigmented area contained more melanized, mature melanosomes than those within the hypopigmented areas. Empty immature melanosomes were found in the hypopigmented melanocytes. Parametric multipoint linkage analysis produced a HLOD score of 4.68, with markers on chromosome 2q35-q37.2. A missense mutation (c.1663 C>A, p.Gln555Lys) in ABCB6 was identified in this family by exome and Sanger sequencing. The mutation perfectly cosegregated with the skin phenotype. An additional mutation (g.776 delC, c.459 delC) in ABCB6 was found in an unrelated sporadic patient. No mutation in ABCB6 was discovered in the other two sporadic patients. Neither of the two mutations was present in the 455 controls. Melanocytes showed positive immunoreactivity to ABCB6. Our data add new variants to the repertoire of ABCB6 mutations with DUH.

Loin pain hematuria syndrome (LPHS) is a painful and incapacitating condition that typically affects young women. Treatment options, including opiates and/or surgical denervation of the renal nerves by autotransplantation, have variable success. In this report, we describe the successful use of endovascular renal nerve ablation in this population. Four women with LPHS and intractable pain unresponsive to conservative measures underwent endovascular ablation of the renal nerves between July and November 2015 using the Vessix renal denervation system. The number and frequency of pain medications and responses to the EQ-5D, McGill Pain Questionnaire, Geriatric Depression Score, 36-Item Short-Form Health Survey, and Oswestry Disability Index were measured at baseline and 3 and 6 months postprocedure to evaluate changes in pain, disability, quality of life, and mood. There were improvements in pain, disability, and quality of life from baseline to 6 months postprocedure. By 6 months, 2 of 4 patients had discontinued all pain medications, whereas the other 2 had reduced their doses of these medications by 75%. These results suggest that percutaneous catheter-based renal nerve ablation with radiofrequency energy may be a treatment option for some patients with LPHS. Crown Copyright © 2016.

Microscopic or occult hematuria, when reflex testing is not good laboratory practice.

PubMed

Froom, Paul; Barak, Mira

2010-01-01

Consensus opinion suggests that hematuria found by dipstick and not confirmed on microscopic examination (<2 erythrocytes per high power field) signifies a false-positive reagent strip test result. Standard practice is to repeat the dipstick test several days later and if still positive to confirm by microscopic examination. If discordant results are obtained, experts recommend reflex testing for urinary myoglobin and hemoglobin concentrations. The question is whether or not this approach represents good laboratory practice. These recommendations are not evidence based. We conclude that the reference range for red blood cells on the reagent strip should be increased to 25x10(6) cells/L for young men, and 50x10(6) cells/L for the rest of the adult population, ranges consistent with flow cytometry reports. Confirmation reflex testing using tests that have inferior sensitivity, precision and probably accuracy is not recommended.

Pancreatic Anastomosis Leak 15 Years after Simultaneous Pancreas-Kidney Transplantation from Late-Onset Allograft Cytomegalovirus Duodenal Ulcers Presenting with Gross Hematuria

Cytomegalovirus (CMV) infection is one of the most important causes of morbidity and mortality in solid organ transplantation. It can present with hematuria, the most common urological complication in the early post-simultaneous pancreas-kidney (SPK) transplant period. In SPK transplantation, CMV infection usually occurs 1 month after transplantation. We report an instance of bladder-drained SPK transplant presenting with recurrent gross hematuria from CMV infected duodenal graft ulcers 15 years after preserved well-functioning grafts. Serum quantitative Polymerase Chain Reaction (qPCR) for CMV was negative. Postmortem duodenal graft staining for CMV was positive, and revealed the cause of the inciting ulcer. To our knowledge, our patient is the first reported case of very late onset invasive CMV disease causing duodenal graft ulcers 15 years after transplantation, as previously reported cases of posttransplant CMV disease occurred only as late as 18 months. In addition, the absence of correlation between CMV viremia and CMV-infected duodenal allograft in SPK transplant has not been reported. Our case demonstrates that CMV viral load is -unreliable to diagnose invasive CMV disease, and tissue biopsy should be obtained to avoid missed diagnosis causing high morbidity and mortality.

Persistent hematuria is one of the most dreaded complications following percutanous nephrolithotomy (PCNL). Although invasive, a catheter-based angiogram is usually used to localize the bleeding vessel and subsequently embolize it. Advances in imaging technology have now made it possible to use a non invasive multi-detector computed tomography (MDCT) angiogram with 3-D reconstruction to establish the diagnosis. We report a case of post-PCNL hemorrhage due to a pseudo aneurysm that was missed by a conventional angiogram and subsequently detected on MDCT angiogram.

A novel mutation of the CLCN1 gene associated with myotonia hereditaria in an Australian cattle dog.

PubMed

Finnigan, Daniel F; Hanna, W J Brad; Poma, Roberto; Bendall, Andrew J

2007-01-01

Heritable myotonia is a genetic muscle disorder characterized by slow relaxation of skeletal muscles. The main clinical signs are skeletal muscle stiffness, especially after vigorous contraction, and muscle hypertrophy. Muscle stiffness may be enhanced by inactivity, and often is relieved by exercise. Myotonia can be inherited in an autosomal dominant or recessive manner (Thomsen- or Becker-type myotonia, respectively). In mice, goats, Miniature Schnauzer dogs, and most affected humans, the disorder is caused by mutations in CLCN1, which encodes the skeletal muscle voltage-gated chloride channel, Cl1C-1. We hypothesized that an Australian Cattle Dog with generalized muscle stiffness and hypertrophy examined at the Ontario Veterinary College would have a mutation in the CLCN1 gene. A pure-bred Australian Cattle Dog from Ontario, Canada, was used. Based on clinical signs and electromyographic test results, a diagnosis of myotonia hereditaria was made, and a muscle biopsy was collected for genetic analysis. Sequence data obtained from the affected dog confirmed that it was homozygous for a single base insertion in the CLCN1 coding sequence. This mutation would result in a truncated ClC-1 protein being expressed, which, based on molecular evidence from other studies, would result in functionally compromised chloride conduction in the skeletal muscles of the animal. To the authors' knowledge, this report describes the Ist case of myotonia in an Australian Cattle Dog and represents the 1st non-Schnauzer canine myotonia to be genetically characterized. In addition, we developed a polymerase chain reaction-based genetic screen to detect heterozygotes with this mutation in the at-large Australian Cattle Dog population.

A Prospective Blinded Evaluation of Urine-DNA Testing for Detection of Urothelial Bladder Carcinoma in Patients with Gross Hematuria.

Retrospective studies have provided proof of principle that bladder cancer can be detected by testing for the presence of tumor DNA in urine. We have conducted a prospective blinded study to determine whether a urine-based DNA test can replace flexible cystoscopy in the initial assessment of gross hematuria. A total of 475 consecutive patients underwent standard urological examination including flexible cystoscopy and computed tomography urography, and provided urine samples immediately before (n=461) and after (n=444) cystoscopy. Urine cells were collected using a filtration device and tested for eight DNA mutation and methylation biomarkers. Clinical evaluation identified 99 (20.8%) patients with urothelial bladder tumors. With this result as a reference and based on the analysis of all urine samples, the DNA test had a sensitivity of 97.0%, a specificity of 76.9%, a positive predictive value of 52.5%, and a negative predictive value of 99.0%. In three patients with a positive urine-DNA test without clinical evidence of cancer, a tumor was detected at repeat cystoscopy within 16 mo. Our results suggest that urine-DNA testing can be used to identify a large subgroup of patients with gross hematuria in whom cystoscopy is not required. We tested the possibility of using a urine-based DNA test to check for bladder cancer in patients with visible blood in the urine. Our results show that the test efficiently detects bladder cancer and therefore may be used to greatly reduce the number of patients who would need to undergo cystoscopy.

Hypercalciuria might be revealed during the differential diagnosis of hematuria accompanying renal lithiasis (RL). In spite of this, diagnostic accuracy of calcium urinary excretion might be affected by incomplete 24-hour urine collections. In the present study, the diagnostic utility of calcium/creatinine (ICaCre) index for determining hypercalciuria associated with non-glomerular hematuria (NGH) and RL was assessed. ICaCre (mg/mg) index was calculated from calcium (mmol/l) and creatinine (µmol/l) concentrations in an aliquot from a 24-hour urine collection in 169 children and adolescents with NGH or RL. Calciuria values > 4.0 mg/kg in 24 hours were distributed according to the presence of NGH or RL. Mean ICaCre index was 0.2 ± 0.1 mg/mg. Calciuria values estimated from ICaCre were statistically higher to those from 24-hour urine collection (p < 0.05). The frequency of hypercalciuria was independent from the measurement method (estimated from ICaCre 39.5% vs. 24 h collection 32.1%; p > 0.05). Hypercalciuria distribution was as follows: no NGH + no RL: 59.0%; no NGH + RL: 60.0% (∆ = +1.0%); NGH + no RL: 68.2% (∆ = +9.2%); NGH + RL: 73.3% (∆ = +14.4%). The use of ICaCre index for determining calcium urine excretion might be effective in the study of hypercalciuria associated with NGH and RL. Copyright: © 2018 Permanyer.

Background As a genetic disorder of abnormal pigmentation, the molecular basis of dyschromatosis universalis hereditaria (DUH) had remained unclear until recently when ABCB6 was reported as a causative gene of DUH. Methodology We performed genome-wide linkage scan using Illumina Human 660W-Quad BeadChip and exome sequencing analyses using Agilent SureSelect Human All Exon Kits in a multiplex Chinese DUH family to identify the pathogenic mutations and verified the candidate mutations using Sanger sequencing. Quantitative RT-PCR and Immunohistochemistry was performed to verify the expression of the pathogenic gene, Zebrafish was also used to confirm the functional role of ABCB6 in melanocytes and pigmentation. Results Genome-wide linkage (assuming autosomal dominant inheritance mode) and exome sequencing analyses identified ABCB6 as the disease candidate gene by discovering a coding mutation (c.1358C>T; p.Ala453Val) that co-segregates with the disease phenotype. Further mutation analysis of ABCB6 in four other DUH families and two sporadic cases by Sanger sequencing confirmed the mutation (c.1358C>T; p.Ala453Val) and discovered a second, co-segregating coding mutation (c.964A>C; p.Ser322Lys) in one of the four families. Both mutations were heterozygous in DUH patients and not present in the 1000 Genome Project and dbSNP database as well as 1,516 unrelated Chinese healthy controls. Expression analysis in human skin and mutagenesis interrogation in zebrafish confirmed the functional role of ABCB6 in melanocytes and pigmentation. Given the involvement of ABCB6 mutations in coloboma, we performed ophthalmological examination of the DUH carriers of ABCB6 mutations and found ocular abnormalities in them. Conclusion Our study has advanced our understanding of DUH pathogenesis and revealed the shared pathological mechanism between pigmentary DUH and ocular coloboma. PMID:24498303

Isolated microscopic hematuria (IMH) is not uncommon in potential kidney donors. The aim was to study the kidney biopsy findings of potential kidney donors with IMH and the impact of the histopathologic diagnoses on the decision to accept or decline such donors from kidney donation. In this retrospective study, all the potential kidney donors with IMH were identified from the medical records of patients who underwent kidney biopsies between January 2010 and December 2016. Forty-five such individuals were identified. The mean age of these potential donors was 32.6 years and 76% were male. All of them had normal blood pressure and no significant proteinuria. Seventeen (38%) biopsies showed histopathologic abnormalities; thin basement membrane disease (n = 13; 28%) was the most common cause followed by immunoglobulin (Ig)A nephropathy (n = 4; 9%). Donors with abnormal biopsy findings were excluded from donation. However, 62% of the potential donors had normal kidney biopsy findings and were accepted for kidney donation. IMH justifies extensive work-up including kidney biopsy to identify donors who may have underlying significant glomerular pathology excluding them from kidney donation. On the other hand, kidney biopsy also helps in accepting the donors if it does not show significant abnormality. Copyright © 2017 Elsevier Inc. All rights reserved.

Incidence of refractory hematuria of prostatic origin (RHPO) is extremely rare, with an iatrogenic etiology even rarer. When conservative methods fail to control bleeding, more invasive surgical methods are needed. In this article we describe our experience with prostatic artery embolization (PAE) as a minimally invasive alternative treatment option in patients with RHPO secondary to iatrogenic urologic trauma. Three patients presented with RHPO. The etiologies were transurethral resection of prostate surgery, Foley catheter removal with a supratherapeutic international normalized ratio and self-traumatic Foley catheter removal respectively. Stepwise management with conservative and medical methods failed to control bleeding. Under local anesthesia and moderate sedation, bilateral PAE was performed via a right common femoral artery access and using cone beam computed tomography. An embolic mixture containing 300-500 um Embosphere® Microspheres (Biosphere Medical, Rockland, MA) was injected under fluoroscopic guidance until stasis was achieved. PAE using the described technique was a technical and clinical success in all three patients. Hematuria resolved within a period of 24 hours. There were no intra- or periprocedural complications. PAE offers a reasonable option in treatment of RHPO, regardless of the cause and may be attempted prior to surgical techniques or sometimes in conjunction. Being minimally invasive and performed under local anesthesia, PAE is especially useful when excessive bleeding prevents adequate visualization of a bleeding source during cystoscopy and in the elderly age group with several comorbidities. An added advantage is the prostatic parenchymal ischemia leading to significant prostate volume reduction and alleviation of the obstructive symptoms. Copyright © 2016 Elsevier Inc.

We report a case of urinary schistosomiasis in an adolescent refugee from Gambia (arrived to Italy illegally), who was brought to the Emergency Department of our hospital. The patient complained of gross hematuria and, in the absence of clinical evidence of bacterial urinary infection, was admitted to the pediatric ward, considering his provenience and social setting. An appropriate collection and microscopic analysis of urine samples led to the detection of bilharzia. Much attention should be paid to this emerging disease in Europe by physicians in order to recognize and treat it timely, which could prevent future and higher costs for public health systems and could reduce the potential risk of environmental spreading. In fact, there are some areas in Italy where the parasite can find its intermediate host to complete its lifecycle.

Iliac Artery-Uretero-Colonic Fistula Presenting as Gastrointestinal Hemorrhage and Hematuria: A Case Report.

Kurata, Saya; Tobu, Shohei; Udo, Kazuma; Noguchi, Mitsuru

2018-01-01

Background: The experience with uretero-arterial fistulas has been limited. However, the aggressive treatment of pelvic tumors with surgical resection and radiotherapy, along with liberal use of ureteral catheters, has been attributed to an increase in their incidence. Unless they are promptly diagnosed and treated, uretero-arterial fistulas are associated with considerably high rates of morbidity and mortality. Urologists need maintain a high degree of suspicion for uretero-arterial fistula in high-risk patients. We herein present the clinical course of an iliac artery-uretero-colonic fistula. Case Presentation: A 67-year-old woman with a history of colon cancer who underwent laparoscopic high anterior resection in July 2010. A ureteral stent inserted to right ureteral stricture, which developed as a result of local recurrence of the tumor in September 2010. She had undergone chemoradiotherapy, but the lesion had slowly increased in size. During the replacement of the ureteral stent in April 2016, she immediately experienced bladder tamponade, bloody bowel discharge, and hypotension. Contrast CT revealed a complex fistula between the right distal ureter and the right internal iliac artery. Furthermore, contrast medium flowed into the intestinal tract through the tumor. The patient was therefore diagnosed with internal iliac artery-uretero-colonic fistula. Arteriography revealed a right uretero-internal iliac artery fistula, and the embolization of the right internal iliac artery was performed. The right ureteral stent was removed. Her hematuria and bloody bowel discharge disappeared, but right nephrostomy was performed because she presented with acute pyelonephritis to ureteral obstruction. Conclusion: In the present case, the uretero-arterial fistula was caused by the long use of an indwelling stent, chemoradiotherapy, infection, and an increase in the size of the lesion. When a suspected uretero-arterial fistula is accompanied by bloody bowel discharge, we

Congenital eye malformations are the second most common cause of childhood blindness and are originated by disruption of the normal process of eye development during embryonic stage. Their etiology is variable, although monogenic causes are of great importance as they have a high risk of familial recurrence. Included among the most severe congenital eye abnormalities are microphthalmia, defined by an abnormally small eye, and anophthalmia, characterized by congenital absence of ocular structures. The currrent knowledge of the genes involved in human microphthalmia and anophthalmia in humans is revised in this work. Copyright: © 2017 SecretarÍa de Salud.

2013-01-01

Purpose The majority of blunt renal trauma is a consequence of motor vehicle collisions and falls. Prior publications based on urban series have shown that significant renal injuries are almost always accompanied by gross hematuria alone or microscopic hematuria with concomitant hypotension. We present a series of blunt renal trauma sustained during recreational pursuits, and describe the mechanisms, injury patterns and management. Materials and Methods Database review from 1996 to 2009 identified 145 renal injuries. Children younger than age 16 years, and trauma involving licensable motor vehicles, penetrating injuries and work related injuries were excluded from analysis. Grade, hematuria, hypotension, age, gender, laterality, mechanism, management, injury severity score and associated injuries were recorded. Results We identified 106 patients meeting the criteria and 85% of the injuries were snow sport related. Age range was 16 to 76 years and 92.5% of patients were male. There were 39 grade 1 injuries, 30 grade 2, 22 grade 3, 12 grade 4 and 3 grade 5 injuries. Gross hematuria was present in 56.7%, 77.2% and 83.3% of grade 2, grade 3 and grade 4 injuries, respectively. None of the patients with grade 2 or greater injuries and microscopic hematuria had hypotension except 1 grade 5 pedicle injury. The nephrectomy and renorrhaphy rate for grade 1 to grade 4 injuries was 0%. Conclusions Compared to urban series of blunt renal trauma, recreationally acquired injuries appear to follow different patterns, including a paucity of associated injuries or hypotension. If imaging were limited to the presence of gross hematuria, or microscopic hematuria with hypotension, 23% of grade 2 to grade 4 injuries would be missed. Men are at higher risk than women. However, operative intervention is rarely helpful. PMID:22591969

BK virus-associated hemorrhagic cystitis (BKV-HC) is a common and major cause of morbidity in recipients of allogeneic hematopoietic stem cell transplantation. A 32-year-old woman developed severe BKV-HC on day 24 after cord blood transplantation (CBT). Despite supportive therapies - such as hyperhydration, forced diuresis, and urinary catheterization - macroscopic hematuria and bladder irritation persisted for over a month. Hyperbaric oxygen (HBO) therapy at 2.1 atmospheres for 90 min per day was started on day 64 after CBT. Macroscopic hematuria resolved within a week, and microscopic hematuria was no longer detectable within 2 weeks. Hematuria did not recur after 11 sessions of HBO therapy, and no significant side effects were observed during or after treatment. HBO therapy could thus be useful in controlling refractory BKV-HC after CBT. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Klippel-Trenaunay-Weber syndrome (KTWS) is a congenital condition characterized by vascular malformations of the capillary, venous and lymphatic systems associated to soft tissue and bone hypertrophy in the affected areas. This syndrome may involve bladder, kidney, urethra, ureter and genitals. We report the treatment of 7 KTWS patients with urogenital involvement. From 1995 to 2005, 7 patients with KTWS were evaluated and the charts of these patients were reviewed. Patients' median age was 19-years (range 4 to 46-years) and only 1 was female. The clinical presentation included genital deformities in 3 cases, hematuria in 2 and urethrorragia in 2, one of which associated with cryptorchidism and phimosis. Three patients had an association of pelvic and genital malformations, including 2 patients with hematuria due to vesical lesions and 1 patient with left ureterohydronephrosis due to a pelvic mass. Two patients had urethral lesions. Treatment included endoscopic laser coagulation for 1 patient with recurrent hematuria and 1 patient with urethrorrhagia, pelvic radiotherapy for 1 patient with hematuria and circumcision in 2 patients with genital deformities. One patient required placement of a double-J catheter to relieve obstruction. Hematuria and urethrorragia were safely and effectively controlled with laser applications. Circumcision was also effective. The patient treated with radiotherapy developed a contracted bladder and required a continent urinary diversion. Urogenital involvement in patients with KTWS is not rare and must be suspected in the presence of hematuria or significant cutaneous deformity of the external genitalia. Surgical treatment may be warranted in selected cases.

Background: Renal stones, urinary tract infections (UTI) and gross hematuria (GH) are the most important renal manifestations of autosomal dominant polycystic kidney disease (ADPKD). They are not only common, but are also frequent cause of morbidity, influencing renal dysfunction. The aim of this study was to evaluate the frequency of these manifestations in our patients with ADPKD and their impact on renal function. Methods: One hundred eighty ADPKD patients were included in the study. Subjects were studied for the presence of UTI, gross hematuria frequency and responsible factors of nephrolithiasis. Survival times were calculated as the time to renal replacement therapy or time of serum creatinine value up to 10 mg/dl. Kaplan-Meier product-limit survival curves were constructed, and log rank test was used to compare the survival curves. Results: Kidney stones were present in 76/180 (42% of pts). The stones were composed of urate (47%) calcium oxalate (39%), and other compounds 14%. UTI was observed in 60% (108 patients). Patients treated with urinary disinfectants had a significant lower frequency of urinary infection (p<0.001) and hematuria (p<0.001) after one year than untreated patients. Gross hematuria was present in 113 patients (63%). In 43 patients hematuria was diagnosed before age 30 (38%), while in 70 patients it was diagnosed after age 30 (62%). Conclusions: UTI is frequent in our ADPKD patients. The correct treatment of UTI decreases its frequency and has beneficial role in the rate of progression to renal failure in ADPKD patients. Patients with recurrent episodes of gross hematuria may be at risk for more severe renal disease. PMID:19918304

This study aimed evaluate the safety and feasibility of endoscopic potassium titanyl phosphate (KTP) laser application in the management of patients with radiation-induced hemorrhagic cystitis (RHC). We retrospectively reviewed the records of 20 patients with RHC who underwent endoscopic KTP laser ablation of telangiectatic bladder vessels between October 2005 and January 2013. After initial cystoscopy, KTP laser was used to ablate the submucosal vasculature while preserving the overlying mucosa. The surgical outcome was evaluated by duration of hematuria-free interval, number of episodes of hematuria, and number of required medical and/or surgical interventions after initial treatment. Overall, 20 patients underwent 26 sessions of KTP laser ablation of bladder vessels. The procedure was able to stop bleeding 92% of the time and the average hematuria-free interval after ablation was 11.8 months, with a range of 1-37 months. In 13 patients (65%) hematuria resolved after 1 session of KTP laser treatment, whereas 5 patients (25%) required multiple sessions. Two patients (10%) with severe hematuria continued to have bleeding after laser treatment, which necessitated proximal diversion of urine with percutaneous nephrostomy tubes to control bleeding. This study suggests that KTP laser, with its unique photoselectivity property, is a safe, effective, and durable treatment with minimal side effects for ablation of submucosal bladder vessels in patients with RHC.

Sole Dependence on Urine Testing Strips and the Ability to Identify Clinically Significant Disease: Challenging the Current Paradigm for Heme Detection in General Clinical Situations.

PubMed

Rothschild, Bruce

2016-05-01

The ability of health care professionals to provide patient care is potentially compromised when predicated on untested, although longstanding, perspectives. One such example is urinalysis testing, which has been currently simplified to use only urine testing strips for detection of microscopic hematuria. To determine whether urine testing strips are sufficient for identification of clinically significant findings in urinalysis. To determine the presence of microscopic hematuria, I examined a collection of urine specimens that had tested heme negative during the 3-month study period. Of the 342 patients from whom urine specimens were examined during this interval, 50 had microscopic hematuria, despite having tested negative for heme via urine testing strip. Also, 30% were not receiving any medication known to produce microscopic hematuria, and 18% had clinically significant pathology. Diagnosis of significant clinical pathologic manifestations would have been compromised had microscopic examination not been performed on the urine specimens from the cohort individuals. Examination of the novel approach of including microscopic examination of specimens in a specific clinical situation challenges the dominant paradigm of reliance on assaying using urine testing strips only, revealing that the current method is not only unreliable for determining microscopic hematuria but also is less than optimal in general clinical practice. The findings of this study provide evidence of the importance of microscopic evaluation as a routine component of urinalysis. © American Society for Clinical Pathology, 2016. All rights reserved.

Uterine rupture is the primary concern when a patient chooses a trial of labor after a cesarean section. Bladder rupture accompanied by uterine rupture should be taken into consideration if gross hematuria occurs. We report the case of a patient with uterine rupture during a trial of labor after cesarean delivery. She had a normal course of labor and no classic signs of uterine rupture. However, gross hematuria was noted after repair of the episiotomy. The patient began to complain of progressive abdominal pain, gross hematuria and oliguria. Cystoscopy revealed a direct communication between the bladder and the uterus. When opening the bladder peritoneum, rupture sites over the anterior uterus and posterior wall of the bladder were noted. Following primary repair of both wounds, a Foley catheter was left in place for 12 days. The patient had achieved a full recovery by the 2-year follow-up examination. Bladder injury and uterine rupture can occur at any time during labor. Gross hematuria immediately after delivery is the most common presentation. Cystoscopy is a good tool to identify the severity of bladder injury. Copyright © 2010 Elsevier. Published by Elsevier B.V. All rights reserved.

This study sought to evaluate factors associated with unplanned hospital return (UR) following transurethral resection of bladder tumor (TURBT), the largest source of readmission among ambulatory urological procedures. A retrospective review of TURBTs at a single academic institution between April 2011 and August 2014 was performed. Demographics, comorbidities, length of stay, tumor size and multiple other factors were recorded. UR was recorded within 30 days of surgery. Bivariate and multivariable analyses were performed to determine factors associated with UR. Among 708 patients undergoing TURBT, 23.9% were female with a mean age of 70 years. The rate of UR was 10.9%. The most common cause of UR was gross hematuria, accounting for 70%. On bivariate analysis, Foley catheter placement in the operating room, non-aspirin anticoagulation and index length of stay longer than 24 h were associated with hematuria-related UR (p < 0.05). Preoperative antibiotics, female gender and aspirin therapy were associated with lower rates of hematuria-related UR (p < 0.05), while tumor size, distance of residence to the hospital, and Foley on hospital discharge (rather than from the operating room) had no association (p > 0.05). On multivariable analysis, only Foley placement in the operating room remained associated with higher rates of hematuria-related UR, while preoperative antibiotics, female gender and aspirin therapy remained associated with a lower likelihood of this event. UR following TURBT is common and typically results from gross hematuria. Patients with postoperative Foley catheterization in the operating room may require additional counseling or supervision before discharge, and should be considered for discharge with a Foley rather than having a prompt voiding trial.

Renal arteriovenous fistula (RAVF) is a comparatively rare malformation. Here, we report a case of ruptured RAVF that was successfully treated by catheter embolization. An 89-year-old female was transferred to our institution with massive gross hematuria in March 2011. Plain abdominal computed tomography (CT) revealed dilated left renal pelvis with high-density contents. Hematoma was suspected. Subsequent plain abdominal magnetic resonance imaging revealed left hydronephrosis and blood retention in the dilated left renal pelvis. No renal or ureteral cancer was evident. Hematuria was conservatively treated using hemostatic agents but hematuria persisted. Repeated urinary cytology revealed no malignant cells. On day 9, the patient went into septic and/or hemorrhagic shock. Fluid and catecholamine infusion, blood transfusion, and antibacterial drugs were rapidly initiated, and the patient's general condition gradually improved. Contrast-enhanced abdominal CT revealed marked expansion of the hematoma in the renal pelvis and microaneurysms in the segmental arteries of the left kidney. Inflammation improved, and a left double-J stent was inserted. Selective renal angiography revealed RAVF with microaneurysms in the left segmental arteries; therefore, catheter embolization using metallic coils was performed, which resolved hematuria. We report a case of ruptured renal arteriovenous malformation, which was successfully treated by catheter embolization.

The goal of this study was to determine the health effects of living downstream from mines in the Potosí region of Bolivia. Histories, physical examinations, and urinalyses were completed on adults recruited from mining and nonmining villages in Bolivia. Blood concentrations of Cd, Hg, and Pb were determined in a subset of participants. Multiple logistic regression analyses were performed. Mining region participants had significantly higher frequencies of hypertension, hematuria, and ketonuria. Hematuria was significantly elevated among those watering livestock downstream from mines and eating grains from their own farm (odds ratio = 4.3; 95% confidence interval, 1.1 to 17.7). Significantly higher blood concentrations of Pb were observed in a subsample of participants with hematuria (4.80 μg/dL vs 10.91 μg/dL; P = 0.026). Efforts to abate environmental exposure to toxic metals seem warranted.

The objective of this study was to assess the long-term prognosis of nephropathy findings and the incidence of new abnormal clinical renal findings in patients with rheumatoid arthritis (RA). The original population-based cross-sectional study of 604 RA patients was carried out in 1988, 103 nephropathy patients being found. Controls matched for age, sex, and duration of RA were selected from among RA patients with normal renal function and urinalysis in 1988. In 2003, a follow-up study was made of the 103 nephropathy patients and 102 controls, and the median follow-up time was 13 years. In the original nephropathy group, serum creatinine exceeded 200 mumol/l in 8% of the original isolated hematuria patients, in 30% of the isolated proteinuria patients, in 57% of the combined hematuria and proteinuria patients, but in none of the isolated chronic renal failure (CRF) patients (p = 0.001 for the difference). Probable or definitive renal amyloidosis was diagnosed in 19% of the nephropathy patients. Dialysis therapy was given to 10 out of the 103 nephropathy patients, nine of them belonging to the original isolated proteinuria or combined hematuria and proteinuria groups. There were six renal deaths among the nephropathy patients, and none in the controls. In the control group, new abnormal renal findings, in most cases mild, were detected in 28%. Serum creatinine exceeded 200 mumol/l in 4% of the controls, and dialysis therapy was given to 2% of the controls. Probable or definitive renal amyloidosis was diagnosed in 4% of this group. With regards to the development or progression of chronic renal failure, the long-term clinical prognosis of isolated hematuria and isolated CRF was found to be favorable. Proteinuria alone or combined with hematuria or CRF was related to evidently poorer prognosis.

To examine the epidemiology and timing of penile fracture, patterns of urethral evaluation, and risk factors for concomitant urethral injury. The National Inpatient Sample (2003-2011) was used to identify patients with penile fractures. Clinical data included age, race, comorbidity, insurance, hospital factors, timing, hematuria, and urinary symptoms. Rates of formal urethral evaluation (cystoscopy or urethrogram) and urethral injury were calculated. Multivariate logistic regression was used to identify predictors of urethral evaluation and risk factors for urethral injury. A weighted population of 3883 patients with penile fracture was identified. Presentations during weekends (37%) and summers (30%) were overrepresented (both P <.001). Urethral evaluation was performed in 882 patients (23%). Urethral injury was diagnosed in 813 patients (21%) with penile fracture. There was an increased odds of urethral evaluation with hematuria (odds ratio [OR] = 2.99; 95% confidence interval [CI], 1.03-8.73; P = .045) and a decrease for Hispanics (OR = 0.42; 95% CI, 0.22-0.82; P = .011). Older age (32-41 years: OR = 1.84; 95% CI, 1.07-3.16; P = .027; >41 years: OR = 2.25; 95% CI, 1.25-4.05; P = .007), black race (OR = 1.93; 95% CI, 1.12-3.34; P = .018), and hematuria (OR = 17.03; 95% CI, 3.20-90.54; P = .001) were independent risk factors for urethral injury. Penile fractures, which occur disproportionately during summer and weekends, were associated with a 21% risk of urethral injury. Urethral evaluations were performed in a minority of patients. Even in patients with hematuria, 55% of patients underwent formal urethral evaluation. On multivariate analysis of patients with penile fracture, hematuria as well as older age and black race were independently associated with concomitant urethral injury. Copyright © 2015 Elsevier Inc.

Background: We investigated whether extracorporeal shock wave (ECSW) therapy can attenuate cyclophosphamide (CYP)-induced acute interstitial cystitis (AIC) in rats. Methods and Results: Eighteen male-adult Sprague-Dawley rats were equally divided into group 1 (sham control), group 2 (AIC induced by 150 mg/kg CYP by intra-peritoneal injection) and group 3 (AIC + ECSW 200 impulses at 0.11 mJ/mm2 to the urinary bladder at 3 and 24 h after CYP treatment). Smooth-muscle cells co-culture with menadione (25 µM) with and without ECSW treatment was performed. Western-blot results demonstrated that ECSW significant attenuated oxidative stress and inflammatory reactions in this in-vitro studies (all p < 0.001). 24-hour urine amount and microscopic findings of red-blood-cell count (i.e., hematuria) were higher in group 2 than in groups 1 and 3, and significantly higher in group 3 than in group 1 (all p < 0.001). The urine levels of albumin and interleukin-6 showed an identical pattern of hematuria among all three groups (all p < 0.001). The cellular and mRNA expressions of macrophage migration inhibitory factor (MIF)+, CD74+, CD68+, substance p+, and Cox-2+ cells in the bladder tissue exhibited an identical pattern of hematuria among all groups (all p < 0.0001). The integrity of epithelial layer and collagen-deposition area as stained by Sirius red displayed an opposite pattern of hematuria among the three groups (p < 0.0001). The protein expression of IL-12, iNOS, TNF-α, NF-κB, MMP-9, NOX-1, NOX-2, RANTES, and Oxyblot displayed an identical pattern of hematuria among all groups (all p < 0.01). Conclusion: ECSW therapy markedly attenuated CYP-induced AIC through inhibitions of the inflammation and oxidative stress. PMID:25628776

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 case is described of an eleven-year-old boy with abdominal pain and hematuria. The hematuria appears to be fabricated by the father of the boy by adding cooked meat to the urine samples. The medical history of the father is very suspect for the Münchhausen syndrome. The case of the son differs in some respects from the normal pattern of the Münchhausen by proxy syndrome: the age of the son, the role of the father as active inducer and the low social class of the family.

During 26 months 200 consecutive patients with fracture of the bony pelvis were evaluated and treated for urological injury. There was no correlation between the extent of pelvic injury and degree of hematuria but hematuria was present in all patients with a urological injury. All urological injuries occurred with anterior arch fractures. The over-all incidence of injury was 13.5 per cent (bladder 9 per cent, urethra 3.5 per cent and combined 1 per cent). Limited extraperitoneal bladder ruptures were treated successfully by Foley catheter drainage.

The role of nonoperative management for penetrating kidney injuries is unknown. Therefore, we review the management and outcome of penetrating kidney injuries at a center with a high incidence of penetrating trauma. Data from all patients presenting with hematuria and/or kidney injury discovered on imaging or at surgery admitted to the trauma center at Groote Schuur Hospital in Cape Town, South Africa during a 19-month period (January 2007 to July 2008) were prospectively collected and reviewed. These data were analyzed for demographics, injury mechanism, perioperative management, nephrectomy rate and nonoperative success. Patients presenting with hematuria and with an acute abdomen underwent a single shot excretory urogram. Those presenting with hematuria without an indication for laparotomy underwent computerized tomography with contrast material. A total of 92 patients presented with hematuria following penetrating abdominal trauma. There were 75 (80.4%) proven renal injuries. Of the patients 84 were men and the median age was 26 years (range 14 to 51). There were 50 stab wounds and 42 gunshot renal injuries. Imaging modalities included computerized tomography in 60 cases and single shot excretory urography in 18. There were 9 patients brought directly to the operating room without further imaging. A total of 47 patients with 49 proven renal injuries were treated nonoperatively. In this group 4 patients presented with delayed hematuria, of whom 1 had a normal angiogram and 3 underwent successful angioembolization of arteriovenous fistula (2) and false aneurysm (1). All nonoperatively managed renal injuries were successfully treated without surgery. There were 18 nephrectomies performed for uncontrollable bleeding (11), hilar injuries (2) and shattered kidney (3). Post-nephrectomy complications included 1 infected renal bed hematoma requiring percutaneous drainage. Of the injuries found at laparotomy 12 were not explored, 2 were drained and 5 were treated with

Hemorrhagic cystitis is a potentially life-threatening complication in patients receiving cancer therapy. This urologic emergency is commonly associated with the chemotherapeutic use of oxazaphosphorine alkylating agents. This report describes a case of hemorrhagic cystitis associated with dacarbazine treatment. A 63-year-old man with asymptomatic metastatic malignant melanoma received 3 cycles of dacarbazine (600-850 mg/m2) monochemotherapy, each 3 weeks apart. Two weeks after the third cycle, he presented with gross hematuria and mild dysuria. Physical examination revealed no significant finding. Hematuria was confirmed by urinalysis, and urinary infection was excluded by repeated urine cultures. Ultrasonography revealed diffuse bladder wall thickening with no discrete mass or ulceration. Cystoscopy findings revealed generalized inflammation and edema of the mucosa of the bladder, confirming the diagnosis of hemorrhagic cystitis. The patient's gross hematuria continued for 2 weeks and then completely resolved with supportive care. Two weeks after complete resolution, the patient experienced 2 transient episodes of gross hematuria that lasted a few hours and subsided spontaneously. Dacarbazine is currently considered the standard first-line treatment in patients with advanced malignant melanoma. At standard prescribed doses (a single dose of 850-1000 mg/m2 or 250 mg/m2 for 5 days per cycle), dacarbazine is a reasonably well tolerated chemotherapeutic drug; nausea, vomiting, and myelosuppression are the most common adverse effects. Association of dacarbazine with hemorrhagic cystitis has not been reported previously (in a PubMed literature search from 1950-2006), and only 1 case report associates temozolomide (an analog of dacarbazine) with hemorrhagic cystitis. Based on the Naranjo adverse drug reactions probability scale, an objective assessment revealed dacarbazine to be a probable cause of hemorrhagic cystitis in this case. This case report suggests that

Hemorrhagic cystitis (HC) is a known complication of oxazophosphorine chemotherapy. BK virus (BKV) has been commonly found to be associated with hematuria in stem cell transplant patients; however, it has rarely been reported after cyclophosphamide chemotherapy alone. The authors present 3 cases of BK viruria with HC in nontransplant pediatric oncology patients. The 3 patients with BKV had more prolonged hematuria (14 to 16 wk) compared with 1 patient with BKV-negative HC (10 wk). The HC necessitated chemotherapy delays and also prolonged supportive care. One patient was treated with intravenous cidofovir with resolution of BK viruria and hematuria. BKV may have an association with the development of HC in nonstem cell transplant patients receiving high-dose oxazophosphorine chemotherapy. HC may present early and be more prolonged in patients with BK viruria. Patients with HC after cyclophosphamide or ifosfamide with negative bacterial cultures should be studied for BKV. Cidofovir may be beneficial in certain patients with BK viruria and HC; however, definitive data will require a clinical trial.

Primary Glomerulonephritis with Unique C4d Deposition and Concurrent Non-infectious Intermediate Uveitis: a Case Report and Literature Review

PubMed Central

2018-01-01

C4 glomerulopathy is a recently introduced entity that presents with bright C4d staining and minimal or absent immunoglobulin and C3 staining. We report a case of a 62-year-old man with C4 glomerulonephritis (GN) and uveitis. He presented to the nephrology department with proteinuria and hematuria. The patient also had intermediate uveitis along with proteinuria and hematuria. A kidney biopsy that was performed in light of continuing proteinuria and hematuria showed a focal proliferative, focal sclerotic glomerulopathy pattern on light microscopy, absent staining for immunoglobulin or C3 by immunofluorescence microscopy, with bright staining for C4d on immunohistochemistry, and electron-dense deposits on electron microscopy. Consequently, C4 GN was suggested as the pathologic diagnosis. Although laser microdissection and mass spectrometry for glomerular deposit and pathologic evaluation of the retinal tissue were not performed, this is the first report of C4 GN in Korea and the first case of coexisting C4 GN and uveitis in the English literature.

Our goal was to establish the clinical presentation and features of pain attacks in children with recurrent abdominal pain (RAP) and urolithiasis. We compared the rate of previous appendectomy among 100 consecutive patients with that of 270 control subjects. We also compared the frequency of pain attacks with that reported by children with functional or organic gastrointestinal RAP. Fifty-three patients had no history of dysuria or gross hematuria, and only 35 had hematuria at the first visit; 41 patients were evaluated for urolithiasis only because of a family history of kidney stones associated with RAP. Twenty-nine patients had been previously hospitalized for abdominal symptoms. Sixteen patients and 4 control subjects (1.5%) had undergone a previous appendectomy (P < .0001). Two to 28 months before the diagnosis of urolithiasis, 37 patients underwent abdominal ultrasonography, which did not show urinary stones. Sixty-nine percent of subjects younger than 8 years of age had central/diffuse abdominal pain. The mean frequency of pain attacks was 4 to 9 times lower than in patients with functional or organic gastrointestinal RAP. Because of the inconstant occurrence of dysuria and hematuria, the location of pain in areas other than the flank, and the lack of calculi shown on imaging studies performed after pain attacks, the urologic origin of pain may be overlooked and ineffective procedures performed. The possibility of urolithiasis should be considered in children with RAP who have a family history of urolithiasis and/or infrequent pain attacks, even when dysuria and hematuria are lacking, and in younger children even when pain is not lateral.

An Overlapping Case of Alport Syndrome and Thin Basement Membrane Disease.

We report a case of a 48-year-old male who presented with hematuria of at least 10 years, and has a daughter with hematuria as well. The patient has a history of degenerative hearing loss, decreased vision and cataract formation, but no diabetes, hypertension or proteinuria. A full serology and urology workup was negative for any abnormality. A kidney biopsy for the patient revealed a diagnosis of Alport syndrome but was unable to rule out thin basement membrane disease. The biopsy was inconclusive in making the diagnosis but the patient's clinical presentation led to the diagnosis of Alport syndrome. The patient's 10-year-old daughter also has hematuria with no clear etiology but now can subsequently be anticipatorily managed for Alport syndrome progression. Due to the rarity of the disease, diagnosis is often missed or delayed by primary care providers especially when no associated proteinuria has yet developed. This can lead to confusion and misdiagnosis with thin basement membrane disease, a generally benign hematuria without kidney failure progression. Additionally, biopsy can be inconclusive in these patients, relying on the physician's history and physical examination findings to diagnose. It is important to appropriately diagnose Alport syndrome not only to manage the patient's rate of kidney failure progression but also allow for a higher degree of suspicion, screening and intervention in the patient's family members. Both the inconclusive nature of kidney biopsies and the usefulness of diagnosis for family member screening are often overlooked in medical literature but are explored in this case.

Severe bleeding in acute immune thrombocytopenic purpura (ITP) is rare but can cause significant complications to the patient. Here we report the case of a pediatric patient with acute ITP and hematuria refractory to anti-D immune globulin, high dose intravenous immunoglobulin G, and high dose steroids. Her hematuria was successfully treated with recombinant factor VIIa (rFVIIa). While further investigation on the use of rFVIIa in ITP is warranted, this case report contributes to the pediatric literature for its use during the course of an initial presentation of ITP with hemorrhagic complications.

Hematuria from a neobladder can occur due to a variety of pathologies including tumors, stones, and fistulas. Variceal bleeding in a neobladder is a very rare condition with only one case reported in literature. We present a case of a patient with cirrhosis and portal hypertension and an ileocolic orthotopic neobladder presenting with hematuria. Computed tomographic angiography showed dilated varices around the neobladder which were successfully embolized. To the best of our knowledge, this is the first report case of variceal bleeding in a neobladder successfully managed with the combination of TIPS (transjugular intrahepatic portosystemic shunt) procedure and embolization.

PurposeTo evaluate the safety, efficacy, and long-term results of endovascular stent graft placement for ureteroarterial fistula (UAF).MethodsWe retrospectively analyzed stent graft placement for UAF performed at our institution from 2004 to 2012. Fistula location was assessed by contrast-enhanced computed tomography (CT) and angiography, and freedom from hematuria recurrence and mortality rates were estimated.ResultsStent graft placement for 11 UAFs was performed (4 men, mean age 72.8 {+-} 11.6 years). Some risk factors were present, including long-term ureteral stenting in 10 (91 %), pelvic surgery in 8 (73 %), and pelvic radiation in 5 (45 %). Contrast-enhanced CT and/or angiography revealed fistulamore » or encasement of the artery in 6 cases (55 %). In the remaining 5 (45 %), angiography revealed no abnormality, and the suspected fistula site was at the crossing area between urinary tract and artery. All procedures were successful. However, one patient died of urosepsis 37 days after the procedure. At a mean follow-up of 548 (range 35-1,386) days, 4 patients (36 %) had recurrent hematuria, and two of them underwent additional treatment with secondary stent graft placement and surgical reconstruction. The hematuria recurrence-free rates at 1 and 2 years were 76.2 and 40.6 %, respectively. The freedom from UAF-related and overall mortality rates at 2 years were 85.7 and 54.9 %, respectively.ConclusionEndovascular stent graft placement for UAF is a safe and effective method to manage acute events. However, the hematuria recurrence rate remains high. A further study of long-term results in larger number of patients is necessary.« less

The purpose of this study is to investigate the changing spectrum and clinicopathologic correlation of biopsy-proven renal diseases in central China. We retrospectively analyzed data of 4931 patients who underwent renal biopsy in ten hospitals between September 1994 and December 2014. Among them, 81.55% were primary glomerular diseases (GD), and 13.02% were secondary GD. IgA nephropathy (IgAN) was the most common primary GD (43.45%), followed by focal glomerulonephritis (16.79%), mesangial proliferative glomerulonephritis (MsPGN, 14.35%), and membranous nephropathy (MN, 13.28%). IgAN was leading primary GD in patients under 60 years old, while MN was the leading one over 60 years old. The most frequent secondary GD was lupus nephritis (LN) (47.35%). The prevalence of IgAN, MN and minimal change disease was found to increase significantly (p < 0.001, p < 0.001, and p < 0.01, respectively), while that of MsPGN, membranoproliferative glomerulonephritis and LN decreased significantly (p < 0.001, p < 0.001, and p < 0.05, respectively). The main indication for renal biopsy was proteinuria and hematuria (49.03%), followed by nephrotic syndrome (NS, 20.36%). IgAN was the most common cause in patients with proteinuria and hematuria, chronic-progressive kidney injury, hematuria and acute kidney injury; and MN was the leading cause of NS. Primary GD remained the predominant renal disease in central China. IgAN and LN were the most prevalent histopathologic lesions of primary and secondary GD, respectively. The spectrum of biopsy-proven renal disease had a great change in the past two decades. Proteinuria and hematuria was the main indication for renal biopsy.

The objective of this study is to evaluate the effects of solifenacin on double-J stent-related symptoms following uncomplicated ureterosocpic lithotripsy (URSL). A total of 70 patients who underwent double-J ureteral stent insertion following URSL were consecutively recruited and received solifenacin postoperatively. Another 70 age- and sex-matched subjects without solifenacin therapy were enrolled as a control group. The clinical data including stone and stent characteristics were collected. All subjects completed the brief-form Ureteral Symptom Score Questionnaire (Chinese-version) to assess the lower urinary tract symptoms, stent-related body pain and hematuria 2 weeks after operation. The severity of stent-related symptoms was compared between two groups. The mean age was 53.8 in solifenacin group and 53.4 years in the control group (p = 0.87). The stone characteristics, stent size, position and curl completeness were similar in both groups. Compared to the control group, solifenacin group had significantly lower total symptom score, urgency and urge incontinence scores. As for stent-related body pain, solifenacin group had significantly less flank, abdominal, urethral pain and hematuria scores (all p < 0.05). The solifenacin versus control group showed significant benefits in lower urinary tract symptoms, stent-related pain and hematuria in both genders (all p < 0.05). Four subjects encountered minor adverse events (5.7 %) and one had urinary retention (1.4 %) in solifenacin group. For patients undergoing URSL and double-J stent indwelling, postoperative solifenacin use was effective and well-tolerated for the treatment of lower urinary tract symptoms, stent-related body pain and hematuria irrespective of genders.

Uninvestigated dyspepsia (UD) is common and only 26.4% of these are peptic ulcer disease, while 50% are non-ulcer dyspepsia. A recent study found that nephrolithiasis with urinary tract infection may have the dyspeptic symptoms. The authors searched for any associations between repeated UD and pyuria, hematuria and other factors. A case-control study was performed. It consisted of 489 patients with repeated UD who had visited community hospitals for at least two times per year and 489 controls sampled from the data of the subjects, free of dyspeptic symptoms, from the multi-stage random survey for subjective health complaints in the same province. Multivariate logistic regression models were used for case-control comparisons. By logistic regression analysis, UD was significantly associated with problems caused by purine-rich foods (PRFs), chronic fatigue, flank paresthesia, hematuria, myofascial pain, and pyuria. The respective adjusted odds ratios and 95% confidence interval (CI) were: 6.67 (4.58, 9.68), 5.06 (3.46, 7.40), 3.98 (2.41, 6.60), 2.97 (2.01, 4.38), 1.91 (1.32, 2.76) and 1.58 (1.01, 2.45). The variables of age (> 48), sex, dysuria, poly-arthralgia, headache and back pain were not significantly associated with UD. The foods that aggravated UD were bamboo shoots, fermented rice noodles, beef alcohol and insects. The rate of pyuria and hematuria was significantly increased with the number of visits within a year [p-value (Chi-square for trend), 0.015 and 0.032]. These findings indicate that pyuria, hematuria, and purine-rich foods were associated with repeated hospital visits for dyspepsia.

To analyze clinical outcomes and the risk factors associated with genitourinary (GU) morbidity and mortality in children who present with hemorrhagic cystitis (HC) after bone marrow transplant (BMT). A retrospective chart review of patients with HC who had undergone BMT at a single pediatric hospital from 2008 to 2015 was conducted. Demographic data, severity of hematuria, HC management, and mortality were analyzed. Bivariate analysis and binary logistic regression were performed to identify risk factors. Out of 43 patients who met inclusion criteria, 67.4% were male with a median age at BMT of 10.2 years (interquartile range 5.8-14.6). Percutaneous nephrostomy catheters were inserted in 5 patients for urinary diversion. All-cause mortality was 32.6% (N = 14). Intravesical retroviral therapy (P <.001), HC grade (P <.001), total Foley time (P <.001), total gross hematuria time (P <.001), total days hospitalized (P = .012), and days to most improved hematuria (P = .032) were associated with significant GU morbidity on bivariate analysis. On multivariable analysis, days to most improved hematuria was associated with significant GU morbidity odds ratio of 1.177 (1.006-1.376) (P = .042). Status of percutaneous nephrostomy was not associated with increased mortality (P = .472); however, in the multivariate model, BK viremia (P = .023), need for renal dialysis (P = .003), and presence of Foley catheter (P = .005) were associated with increased mortality. Children with HC after BMT fall in a very high-risk category with high mortality and significant GU morbidity. The presence of a Foley catheter, need for dialysis, and BK viremia are associated with increased mortality. Copyright © 2016 Elsevier Inc. All rights reserved.

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.

We compared the incidence of hematuria, pyuria and clinical urinary tract infection in patients who performed intermittent self-catheterization using a hydrophilic coated LoFric (Astra Tech AB, Mölndal, Sweden) or standard plastic catheter. A total of 62 male patients who performed intermittent self-catheterization to manage neurogenic bladder were randomized into 2 treatment groups at 3 American study sites. Outcome measures included urinary tract infection, microhematuria, pyuria and satisfaction rates. Of the 62 enrolled patients 49 completed the 12-month study. The withdrawal rate was not different in the 2 groups. At the end of the study there was statistically significantly less hematuria in the hydrophilic coated catheter group compared with controls. In addition, there was a significant decrease in the urinary tract infection rate from baseline in the hydrophilic coated catheter group but not in controls. Use of the hydrophilic coated catheter by patients on intermittent self-catheterization is associated with less hematuria and a significant decrease in the incidence of urinary tract infections. Therefore, it may be preferable for some patients, especially those with a history of difficult catheterization, urethral trauma or a high rate of urinary tract infection.

We present a case of bicornuate uterine horns with complete cervico-vaginal agenesis and associated congenital uterovaginal fistula. The patient presented with cyclical hematuria, amenorrhea, and abdominal lump. The vagina was blind-ending. The cystoscopic examination during cyclical hematuria revealed bloody efflux through a small fistula on the posterior wall of the urinary bladder. The magnetic resonance imaging (MRI) showed bicornuate uterus and cervical agenesis. Hysterectomy and repair of the uterovesical fistula was done. The vagina was reconstructed using an amniotic mould. The report underlies the importance of MRI in diagnosing complexity of such rare anomalies. It also stresses for the need of hysterectomy if cervicovaginal agenesis is present.

To investigate the clinical characteristics and the status of diagnosis and treatment of patients with Alport syndrome in China. Patients with affirmative diagnosis of Alport syndrome from Department of Pedatrics, Peking University First Hospital in the past 20 years (1995-2015) were analyzed retrospectively. The clinical data including initial symptoms, visit reasons, age at onset of disease, family history, hereditary mode, methods of diagnosis, misdiagnosis and mistreatment were collected. A total of 398 patients with Alport syndrome were included in this study, 48.2% of patients had the onset of symptoms before age of 3 years. The rate of onset of symptoms and diagnosis before age of 17 years were 95.7%. The initial symptoms included gross hematuria (37.2%), microscopic hematuria and proteinuria (25.1%), microscopic hematuria (14.8%), edema of eyelid and lower limbs (10.3%), increased foam in urine (4.3%), etc.; 39.5% of patients had no symptoms of urinary tract. Only 14.0% of the patients were diagnosed as Alport syndrome for the first time, and 86.0% of the patients were misdiagnosed. Hormones and immunosuppressive agents were used in 19.0% of patients diagnosed as Alport syndrome, and in 43.0% of patients there was misdiagnosis. Skin biopsy and immunofluorescence of type Ⅳ collagen ɑ5 chain in epithelial basement membrane had a detection rate of 77.8%. Electron microscopy of glomerular basement membrane had a detection rate of 92.6%, and genetic testing 96.6%. The time interval of diagnosis was 18.2 months and was gradually shortened in recent years. Alport syndrome developed at a very young age. Hematuria was the most frequent initial symptom. There was a high rate of misdiagnosis and mistreatment for Alport syndrome. Genetic testing for Alport syndrome had advantages of high detection rate, genetic consultation and prenatal diagnosis.

Sickle cell trait (SCT) carries a small risk of renal medullary carcinoma (RMC). We conducted a systematic literature review and reported new four RMC cases (total N = 217). Eighty eight percent had SCT and 8% had sickle cell disease; 50% were children. Males had 2.4× risk than females. Isolated hematuria or in combination with abdominal or flank pain was the presenting sign in 66% cases. Tumor-related mortality was 95%. Four non-metastatic patients were long-term disease-free survivors. Although risk appears to be very low, individuals with SCT should be informed about the low risk of RMC with the hope of early diagnosis. Hematuria should prompt immediate investigation. © 2015 Wiley Periodicals, Inc.

We present an unusual case of bladder perforation caused by foreign body that was self-inserted in the urethra and consequently slipped inside the bladder in a 29-year-old female patient with psychiatric disease. The patient was referred to our department for macroscopic hematuria and abdominal pain. Imaging studies revealed the presence of a foreign body in the pelvic area which had perforated the left lateral wall of the bladder. The foreign body was removed via open cystotomy. In psychiatric patients hematuria and pelvic pain may result from insertion of a foreign body in the bladder usually during masturbation.

Abdominal aortic aneurysm with spontaneous aorto-left renal vein fistula is a rare but well-described clinical entity usually with abdominal pain, hematuria, and a nonfunctioning left kidney. This report describes a 44-year-old man with left-sided groin pain and varicocele who was treated with conservative measures only. The diagnosis was eventually made when he returned with microscopic hematuria, elevated serum creatinine level, and nonfunction of the left kidney; computed tomography scan demonstrated a 6-cm abdominal aortic aneurysm, a retroaortic left renal vein, and an enlargement of the left kidney. This patient represents the youngest to be reported with aorto-left renal vein fistula and the second case with a left-sided varicocele.

Acute glomerulonephritis (AGN) is a type of renal disease which indicates the inflammation of glomerulus and nephrons. This study was carried on 94 children, <15 years old with the diagnosis of AGN who were admitted to Qom and Yazd's hospitals between 2000 and 2006. Data were collected using hospital records on admission, progression notes and outpatient follow up. Among 94 patients, 55.3% were male and 44.6% were female. Mean age of patients was 8.2±2.7 years old. Acute post streptococcal glomerulonephritis (APSGN) was reported in 92.5%, membranoproliferative glomerulonephritis in 4.2%, hemolytic uremic syndrome in 2.1% and IgA nephropathy in 1.06%. There was no significant differences between GN types and gender (P=0.54). Clinical manifestation included edema in 68.8%, oliguria in 36.3%, gross hematuria in 69.1%, HTN in 61.7% and anuria in 1.06%. Microscopic hematuria was detected in all patients. In the time of follow up none of patients had hypertension, 3.1% had proteinuria and 6.3% had microscopic hematuria. APSGN is the most common causes of AGN in Qom and Yazd's children. Early diagnosis and treatment of APSGN may protect children from long term morbidity and mortality and improve quality of life.

Complications of bladder distension during retrograde urethrography.

1981-05-01

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.

A 5-yr-old female African hedgehog (Ateleris albiventris) presented with hematuria. Vulvar culture results revealed a 4+ growth of Enterococcus sp. and gamma-Streptococcus sp. susceptible to trimethoprim sulfa and enrofloxacin. Ultrasound evaluation of the abdomen revealed an unidentifiable tubular structure in the region of the reproductive tract. An exploratory laparotomy and ovariohysterectomy were performed. Pathologic studies of the uterus showed a uterine spindle cell tumor, uterine endometrial polyp, uterine adenomyosis, and a possible acute infarct resulting in uterine wall necrosis. Hematuria did not reoccur, and the hedgehog lived for another 19 mo until she died from an oral squamous cell carcinoma. To date, this is the first report of a uterine spindle cell tumor in an African hedgehog.

Therapy for BK virus (BKV)-associated hemorrhagic cystitis (BKV-HC) is limited after hematopoietic stem cell transplantation (HSCT). We examined whether choreito, a formula from Japanese traditional Kampo medicine, is effective for treating BKV-HC. Among children who underwent allogeneic HSCT between October 2006 and March 2014, 14 were diagnosed with BKV-HC (median, 36 days; range, 14 to 330 days) after HSCT, and 6 consecutive children received pharmaceutical-grade choreito extract granules. The hematuria grade before treatment was significantly higher in the choreito group than in the nonchoreito group (P = .018). The duration from therapy to complete resolution was significantly shorter in the choreito group (median, 9 days; range, 4 to 17 days) than in the nonchoreito group (median, 17 days; range, 15 to 66 days; P = .037). In 11 children with macroscopic hematuria, the duration from treatment to resolution of macroscopic hematuria was significantly shorter in the choreito group than in the nonchoreito group (median, 2 days versus 11 days; P = .0043). The BKV load in urine was significantly decreased 1 month after choreito administration. No adverse effects related to choreito administration were observed. Choreito may be a safe and considerably promising therapy for the hemostasis of BKV-HC after HSCT. Copyright © 2015 American Society for Blood and Marrow Transplantation. Published by Elsevier Inc.

To investigate the clinical features of pediatric Xp11.2 translocation renal cell carcinoma (RCC). A retrospective review of 22 cases over 35 years. Xp11.2 translocation RCCs were identified in 13 boys and 9 girls with a median age of 10.5 years (range: 2.5-16 years). RCC presented with hematuria in 17, abdominal mass in 1, abdominal masses with hematuria in 2, abdominal pain with hematuria in 1, and as an incidental finding in 1 patient. Ten patients were classified stage I, 10 were stage III, and two were stage IV. Of the 10 patients with stage I RCCs, 3 patients with tumor measuring less than 7 cm had nephron-sparing surgery (NSS) and 17 patients underwent simple nephrectomy. A 15-cm tumor was incompletely removed in one patient and another patient with a 25-cm × 18-cm × 15-cm tumor had gross residual. Of the 15 patients followed up between 6 months and 35 years, 13 were still living and 2 had died after surgery. Xp11.2 translocation RCC is the predominant form of pediatric RCC, associated with advanced stage at presentation. Nephrectomy is the usual treatment for RCC but NSS is an option for patients with tumors measuring<7 cm. Patients with N+M0 maintained a favorable prognosis following surgery alone. © 2014.

Intractable hematuria from the bladder or the prostate can be life-threatening and its management remains a difficult clinical problem. Severe bleeding can arise as a result of radiation cystitis, bladder carcinoma, cyclophosphamide-induced cystitis, severe infection, transurethral resection of the prostate and prostate cancer. When irrigation of the bladder through a three-way catheter and fulguration of the bleeding lesions fail to stop the hematuria, a life-threatening situation can develop, when blood transfusion fails to keep pace with the rate of blood loss. Patients with massive uncontrollable hematuria are often elderly and unfit for cystectomy as a treatment. Many urologists have had to manage this difficult problem, and several different treatments have been attempted and described, with varying degrees of success. Transcatheter arterial embolization of the vesical or prostatic arteries is occasionally indicated in these patients when all other measures have failed. There is limited published experience with this procedure, but success in 90% of patients is reported when the vesical or prostatic arteries can be identified. The aim of this review is to describe the current place of transcatheter arterial embolization in the management of severe bladder or prostate bleeding after failed conservative therapy, and to review its efficacy and morbidity.

A 69-year-old man with history of end-stage-renal disease (ESRD) underwent successful kidney transplantation from a cadaveric donor in November 2011. However, posttransplant recovery was complicated by delayed graft function and recurrent gross hematuria. Serial Doppler ultrasound (US) of the renal allograft demonstrated a pseudoaneurysm with interval increase in size. However, it could not be visualized with other modalities, including an initial angiogram (postoperative day 49) and a second angiogram (postoperative day 68), followed by surgical exploration (postoperative day 71), which demonstrated complete intra-aneurysmal thrombosis on intraoperative Doppler US. Unfortunately, the patient's hematuria continued and a repeat Doppler US 48 hours later demonstrated a persistent pseudoaneurysm. Therefore, on postoperative day 75, we performed targeted percutaneous intra-aneurysmal thrombin injection under dual image guidance, which showed complete intra-aneurysmal thrombosis on intraprocedural Doppler US. Hematuria recurred the next day. A third angiogram (postoperative day 77) finally illuminated the hidden pseudoaneurysm occult on the first and second angiographic studies (sensitivity [index case] 33%) and surgery. This allowed for successful coil embolization of a subsegmental feeding branch with an excellent outcome. We support a more aggressive management with serial angiography and embolization of the intrarenal symptomatic pseudoaneurysm rather than surgery in renal allograft recipients, with the benefits outweighing the risks.

There are no published management schemes for blunt renal injuries. We are conducting a 2-center prospective observational study with a fixed management scheme. Children with CT proven renal injuries were enrolled with permission. Ambulation is allowed when able regardless of grade. Discharge occurs when tolerating a diet and pain is controlled regardless of hematuria. Urinalysis occurs at follow up in 2-4weeks and repeated as indicated. Between 9/2008 and 9/2012, 70 patients were enrolled. Mean age was 11.8years (3-17), and 70% were male. The mean grade of injury was 2.8±1.1 [1-5]. One nephrectomy (1.4%) was performed for a grade 5 injury. Other renal interventions included an embolization for the hilar bleed and one cystotomy for a clot. Mean LOS was 2.9days±2.4days. In patients without other major injury, LOS was 1.9±1.7days (0.4-8days). There were 5 (7%) readmissions: 3 for pain, 1 for hematuria, and 1 for a bladder clot. 58 patients (83%) gave urinalysis samples at initial follow up (med 18days), where 31 (53%) were positive for blood. Children with blunt renal injury may benefit from management without strict bedrest guidelines. Hematuria appears to have little influence on recovery. © 2014.

Dengue is a major public health problem in tropical and subtropical areas worldwide. There is a lack of information on the risk factors for death due to severe dengue fever in developing countries, including Brazil where the state of Amazonas is located. This knowledge is important for decision making and the implementation of effective measures for patient care. This study aimed to identify factors associated with death among patients with severe dengue, in Amazonas from 2001 to 2013. We conducted a retrospective cohort study based on secondary data from the epidemiological surveillance of dengue provided by the Fundação de Vigilância em Saúde do Amazonas, FVS (Health Surveillance Foundation) of the Secretaria de Saúde do Amazonas, SUSAM (Health Secretariat of the State of Amazonas). Data on dengue cases were obtained from the SINAN (Notifiable Diseases Information System) and SIM (Mortality Information System) databases. We selected cases of severe dengue with laboratory confirmation, including dengue-related deaths of residents in the state of Amazonas from January 1, 2001, to December 31, 2013. The explanatory variables analyzed were sex, age, level of education, spontaneous hemorrhagic manifestations, plasma extravasation and platelet count. Patients who died due to severe dengue had more hematuria, gastrointestinal bleeding, and thrombocytopenia than the survivors. Considering the simultaneous effects of demographic and clinical characteristics with a multiple logistic regression model, it was observed that the factors associated with death were age >55 years (odds ratio [OR] 4.98), gastrointestinal bleeding (OR 10.26), hematuria (OR 5.07), and thrombocytopenia (OR 2.55). Gastrointestinal bleeding was the clinical sign most strongly associated with death, followed by hematuria and age >55 years. The study results showed that the best predictor of death from severe dengue is based on the characteristic of age >55 years, together with the clinical signs of

Purpose: To provide a retrospective analysis of the efficacy of hyperbaric oxygen therapy (HBOT) for treating hemorrhagic cystitis (HC) and proctitis secondary to pelvic- and prostate-only radiotherapy. Methods and Materials: Nineteen patients were treated with HBOT for radiation-induced HC and proctitis. The median age at treatment was 66 years (range, 15-84 years). The range of external-beam radiation delivered was 50.0-75.6 Gy. Bleeding must have been refractory to other therapies. Patients received 100% oxygen at 2.0 atmospheres absolute pressure for 90-120 min per treatment in a monoplace chamber. Symptoms were retrospectively scored according to the Late Effects of Normal Tissues-Subjective, Objective,more » Management, Analytic (LENT-SOMA) scale to evaluate short-term efficacy. Recurrence of hematuria/hematochezia was used to assess long-term efficacy. Results: Four of the 19 patients were lost to follow-up. Fifteen patients were evaluated and received a mean of 29.8 dives: 11 developed HC and 4 proctitis. All patients experienced a reduction in their LENT-SOMA score. After completion of HBOT, the mean LENT-SOMA score was reduced from 0.78 to 0.20 in patients with HC and from 0.66 to 0.26 in patients with proctitis. Median follow-up was 39 months (range, 7-70 months). No cases of hematuria were refractory to HBOT. Complete resolution of hematuria was seen in 81% (n = 9) and partial response in 18% (n = 2). Recurrence of hematuria occurred in 36% (n = 4) after a median of 10 months. Complete resolution of hematochezia was seen in 50% (n = 2), partial response in 25% (n = 1), and refractory bleeding in 25% (n = 1). Conclusions: Hyperbaric oxygen therapy is appropriate for radiation-induced HC once less time-consuming therapies have failed to resolve the bleeding. In these conditions, HBOT is efficacious in the short and long term, with minimal side effects.« less

Chart review studies have suggested that point-of-care urine dipstick testing may accurately predict an elevation in serum creatinine (Cr). We aimed to prospectively evaluate the test characteristics of proteinuria/hematuria in predicting elevated serum Cr. A prospective, observational study was conducted between March 2007 and June 2008 at 2 affiliated, urban hospitals with an annual emergency department census of 150,000. Patients undergoing laboratory urinalysis, point-of-care urine dipstick, and a serum chemistry panel were enrolled. Trained research assistants collected data on consecutive patients 18 hours per day using preformatted data forms and entry into an anonymized Access (Microsoft, Seattle, Wash) database. Demographic baseline variables including age, sex, chief complaint, vital signs, and source of sample (catheter vs "clean catch") were also collected. An elevated Cr level was defined as greater than 1.3 based on the laboratory reference range. Standard statistical methods were used to calculate diagnostic test operating characteristics of proteinuria or hematuria as a predictor of elevated serum Cr. Five thousand four hundred sixteen subjects were enrolled with 28.3% male and a mean age of 50.2 years. Elevated serum Cr greater than 1.3 mg/dL was found in 13.9% (755/5416) of subjects. The sensitivity of either proteinuria or hematuria for elevated Cr was 82.5% (95% confidence interval [CI], 80%-85%) and specificity was 34.4% (95% CI, 33%-36%). Positive predictive value was 16.9% (95% CI, 16%-18%) and negative predictive value was 92.4% (95% CI, 91-94%). The likelihood ratio for a positive test was 1.3 (95% CI, 1.1-1.5), and the likelihood ratio for a negative test was 0.5 (95% CI, 0.3-0.8). Although negative predictive value was high, the presence of proteinuria/hematuria was only moderately predictive of elevated serum Cr level. Copyright (c) 2010 Elsevier Inc. All rights reserved.

We selected cases of severe dengue with laboratory confirmation, including dengue-related deaths of residents in the state of Amazonas from January 1, 2001, to December 31, 2013. The explanatory variables analyzed were sex, age, level of education, spontaneous hemorrhagic manifestations, plasma extravasation and platelet count. Patients who died due to severe dengue had more hematuria, gastrointestinal bleeding, and thrombocytopenia than the survivors. Considering the simultaneous effects of demographic and clinical characteristics with a multiple logistic regression model, it was observed that the factors associated with death were age >55 years (odds ratio [OR] 4.98), gastrointestinal bleeding (OR 10.26), hematuria (OR 5.07), and thrombocytopenia (OR 2.55). Gastrointestinal bleeding was the clinical sign most strongly associated with death, followed by hematuria and age >55 years. The study results showed that the best predictor of death from severe dengue is based on the characteristic of age >55 years, together with the clinical signs of

Urinalysis: case presentations for the primary care physician.

Sharp, Victoria J; Lee, Daniel K; Askeland, Eric J

Urinalysis is useful in diagnosing systemic and genitourinary conditions. In patients with suspected microscopic hematuria, urine dipstick testing may suggest the presence of blood, but results should be confirmed with a microscopic examination. In the absence of obvious causes, the evaluation of microscopic hematuria should include renal function testing, urinary tract imaging, and cystoscopy. In a patient with a ureteral stent, urinalysis alone cannot establish the diagnosis of urinary tract infection. Plain radiography of the kidneys, ureters, and bladder can identify a stent and is preferred over computed tomography. Asymptomatic bacteriuria is the isolation of bacteria in an appropriately collected urine specimen obtained from a person without symptoms of a urinary tract infection. Treatment of asymptomatic bacteriuria is not recommended in nonpregnant adults, including those with prolonged urinary catheter use.

Schistosoma haematobium Infection That Mimics Bladder Cancer in a 66-Year-Old Ethnic Egyptian Man.

66-year-old ethnic Egyptian man. Hematuria. The patient had a history of multiple episodes of gross hematuria for the past 5 years. Because the hematuria usually resolved on its own, he did not seek medical attention during that time. Bladder cancer was suspected. The patient had a history of coronary artery disease, hypertension, nephrolithiasis, congestive heart failure, lifelong smoking, and ischemic cardiomyopathy. He has been taking the anticoagulants clopidogrel (Plavix) and warfarin (Coumadin). The patient is originally from Egypt and has been living in the United States for the past 10 years. A complete blood count showed a hemoglobin of 13.0 g per dL (reference range, 14.0 to 18.0 g per dL), hematocrit 40% (40% to 54%), red blood cell count (RBC) 4.65 × 10(9) per L (4.60 to 6.00), and platelet count 179 × 10(9) per L (150 to 450). The urinalysis results showed 3+ protein, 4+ blood, and urine RBC of greater than 100 per high power field (hpf). The urinalysis results did not indicate the presence of parasitic ova or adult parasites. Based on these results, the physician ordered cystoscopic testing, suspecting bladder cancer. Analysis of the bladder tissue showed inflammation (Image 1) and several ova that were consistent with developing Schistosoma (Image 2). Many of the ova were calcified and surrounded by severely inflamed tissue (Image 3). Copyright© by the American Society for Clinical Pathology (ASCP).

Schistosomiasis and malaria are two common parasitic diseases that are co-endemic in resource-poor communities of sub-Saharan Africa. This study aims to assess the effects of single and concomitant Plasmodium falciparum and Schistosoma haematobium infections on two indicators of renal injury in school children in a rural community of Nigeria. A cross-sectional epidemiological survey was carried out on a total of 173 schoolchildren between ages 6 and 18 years (mean age 11.4±2.6 years). Urine and blood samples were collected by standard methods for concurrent microscopic diagnosis of S. haematobium and P. falciparum infections. Urinary blood (hematuria) and protein were determined using a urinalysis dipstick. The prevalence of single infections was 75.1% and 78.2% for S. haematobium and P. falciparum, respectively. A total of 57.1% individuals were infected with the two parasites. The prevalence of hematuria was significantly higher in the co-infection status (63.8%) than in single S. haematobium (52.2%) and P. falciparum (43.7%) infection statuses (p=0.04), while no significant variation was recorded in proteinuria in the three infection statuses (p=0.53). The proportion of children with renal injury associated with the co-infection of these parasites is very high, particularly in young children, who seem to have a higher prevalence of hematuria.

World Kidney Day (WKD) is intended to raise awareness and increase detection of chronic kidney disease (CKD), but most emphasis is placed on adults rather than children. We examined yield of screening for CKD and hypertension among poor children in Mexico. On WKD (2006, 2007), children (age < 18 years) without known CKD were invited to participate at two screening stations. We measured body mass index (BMI), blood pressure, and serum creatinine, and performed dipstick urinalysis. The Schwartz equation was used to estimate glomerular filtration rate (GFR; reduced GFR defined as < 60 ml/min per 1.73 m(2)). Proteinuria and hematuria were defined by a reading of >or= 1+ protein or blood on dipstick. Hypertension was defined by gender, age, and height-specific norms. In total, 240 children were screened (mean age 8.9 +/- 4.1 years; 44.2% male). Proteinuria and hematuria were detected in 38 (16.1%) and 41 (17.5%), respectively; 15% had BMI > 95th percentile for age. Reduced GFR was detected in four (1.7%) individuals. Systolic hypertension was more prevalent in younger children (age 0-8 years, 19.6%; age 9-13 years, 7.1%; age 14-17 years, 5.3%) suggesting a possible white-coat effect. Hematuria, proteinuria, hypertension and obesity were frequently detected among children in a community based screening program in Mexico. This form of screening might be useful in identifying children with CKD and hypertension in developing nations.

To assess whether Foley catheterization of the rectum after transrectal ultrasound (TRUS)-guided prostate biopsy decreases complication rates. Between June 2000 and September 2006, 275 consecutive patients were evaluated after undergoing TRUS-guided prostate biopsy. All procedures were performed on an outpatient basis. Patients were divided into two groups. In the first group (n = 134), a Foley catheter was inserted into the rectum and inflated to 50 cm(3) after TRUS-guided biopsy. In the second group (n = 141), catheterization was performed without balloon placement. Rectal bleeding, hematuria, hematospermia, infection, and acute urinary retention rates were compared between groups. The mean ages of the patients were 63.3 years +/- 5.6 and 62.1 years +/- 7.2 years in the Foley catheter group and control group, respectively (P = .112). Hematuria, hematospermia, infection, and rectal bleeding occurred in 31 (23.1%), 30 (22.4), nine (6.7%), and two patients (1.5%), respectively, in the Foley catheter group; and in 36 (25.5%), 36 (25.5%), 11 (7.8%), and 25 patients (17.7%), respectively, in the control group. The incidences of infection, hematuria, and hematospermia were not significantly different between groups (P > .05). In contrast, the rectal bleeding rate was significantly lower in the Foley catheter group (1.5%) than in the control group (17.7%; P = .001). Although it has no effect on other complications, TRUS-guided prostate biopsy with rectal Foley catheterization is a useful, practical method to decrease or prevent rectal bleeding.

Decker, Kim A

2016-12-01

Six years ago, I was diagnosed with stage IIIA ovarian low malignant cell potential cancer. It was the most shocking situation I have ever experienced. I didn't realize I had any symptoms, except occasional back pain, which I attributed to starting a new workout program. I had scheduled an abdominal computerized tomography (CT) scan for recurrent microscopic hematuria, which my internist wanted to check. I was told I would hear the results in two days. Two hours after my CT scan, while I was eating ice cream and watching television, an on-call genitourinary doctor (who I did not personally know) called to tell me the good news-that I had kidney stones, thus the microscopic hematuria. However, the bad news was that I had ovarian cancer that had spread to my omentum. He said he would call my gynecologist right away.

Background Periodontal disease is common among adults and is associated with an increasing risk of chronic kidney disease (CKD). We aimed to investigate the prevalence and risk factors of CKD in patients with periodontal disease in China. Methods In the current cross-sectional study, patients with periodontal disease were included from Guangdong Provincial Stomatological Hospital between March 2011 and August 2011. CKD was defined as estimated glomerular filtration rate (eGFR) <60 mL/min/1.73 m2, the presence of albuminuria, or hematuria. All patients with periodontal disease underwent a periodontal examination, including periodontal probing pocket depth, gingival recession, and clinical attachment level by Florida Probe. They completed a questionnaire and had blood and urine samples taken. The adjusted prevalence of indicators of kidney damage was calculated and risk factors associated with CKD were analyzed. Results A total of 1392 patients with periodontal disease were invited to participate this study and 1268 completed the survey and examination. After adjusting for age and sex, the prevalence of reduced eGFR, albuminuria, and hematuria was 2.7% (95% CI 1.7–3.7), 6.7% (95% CI 5.5–8.1) and 10.9% (95% CI 9.2–12.5), respectively. The adjusted prevalence of CKD was 18.2% (95% CI 16.2–20.3). Age, male, diabetes, hypertension, history of CKD, hyperuricemia, and interleukin-6 levels (≥7.54 ng/L) were independent risk factors for reduced eGFR. Female, diabetes, hypertension, history of CKD, hyperuricemia, high level of cholesterol, and high sensitivity C-reactive protein (hsCRP) (≥1.03 mg/L) and TNF-α levels (≥1.12 ng/L) were independently associated with an increased risk of albuminuria. Female, lower education (hematuria. Conclusions 18.2% of Chinese patients with periodontal disease have proteinuria, hematuria, or reduced eGFR, indicating the presence of kidney damage. Whether

Late-onset hemorrhagic cystitis (HC) after allogeneic hematopoietic stem cell transplantation (HSCT) has been associated with BK virus (BKV). Antiviral drugs are of limited efficacy and the optimal treatment for HC has not yet been established. Hyperbaric oxygen (HBO) may benefit these patients. We, therefore, retrospectively evaluated the effectiveness of HBO therapy in 16 patients with HC after allogeneic HSCT. All 16 patients had macroscopic hematuria and BKV infection. Patients received 100% oxygen in a hyperbaric chamber at 2.1 atmospheres for 90 min, 5 days per week, with a median 13 treatments (range, 4-84). Fifteen patients (94%) showed complete resolution of hematuria. Median urinary DNA BKV titers declined after HBO (P<0.05). Patients started on HBO earlier after diagnosis of HC responded sooner (P<0.05). HBO was generally well tolerated and proved to be a reliable option for this difficult to manage condition.

Pelvic fracture and injury to the lower urinary tract.

PubMed

Spirnak, J P

1988-10-01

The presence of a urologic injury must be considered in all patients with pelvic fracture. Uroradiographic evaluation starting with retrograde urethrography is indicated in all male patients with concomitant gross hematuria, bloody urethral discharge, scrotal or perineal ecchymosis, a nonpalpable prostate on rectal examination, or an inability to urinate. If the urethra is normal, a catheter may be passed, and in the presence of gross hematuria, a cystogram must be performed. Female patients rarely suffer urethral lacerations. The urethra is examined, and a Foley catheter may be passed without a urethrogram. The immediate management of associated urologic injuries continues to evolve and evoke controversy. Selected cases of extraperitoneal bladder perforation may be safely managed solely by catheter drainage. Intraperitoneal perforations require surgical exploration and repair. Urethral disruption (partial or complete) may be safely managed by primary cystostomy drainage with management of potential complications (stricture, impotence, incontinence) in 4 to 6 months.

To present the case of a 19-year-old female with no significant medical history with confirmed diagnosed of nutcracker syndrome treated successfully by endovascular means. She was referred to the Vascular Surgery Department with a 6-month history of macroscopic haematuria, after other aetiologies were ruled out. Abdominal computed tomography angiography revealed compression of the left renal vein; the patient underwent endovascular treatment, and a 12×16 mm balloon expandable stent was placed with immediate angiographic improvement, decreased pressure gradients and progressive resolution of haematuria. At one year, she remains symptom-free. Nutcracker syndrome is uncommon, and a high index of suspicion is needed. Macroscopic haematuria is not always present, and in our case stent placement demonstrated effectiveness in the resolution of symptoms at 12 months' follow--up.

2012-01-01

Introduction We present the effect of hyperbaric oxygen therapy (HBOT) after radiotherapy for cancer in the pelvic cavity resulting in hematuria. Increasing the pressure of oxygen (PO2) in ischemic tissues favors the formation of new blood vessels and increases the secretion of collagen. Material and methods We evaluated 10 patients who were treated with HBOT from October 2006 to December 2010 due to persistent radiation damage to the lining of the bladder leading to recurrent hematuria. The study group was comprised of seven men and three women. In the case of cervical and endometrial cancers, 30 Gy of brachytherapy with 45-50 Gy of teleradiotherapy were used. In prostate cancer (PCa), we applied 50 Gy of teleradiotherapy with an additional dose of 20-24 Gy, and in the case of bladder cancer (BCa), 50 Gy of teleradiotherapy was applied with an additional dose of 16 Gy. HBOT consisted of 60 HBO2 treatments, in which patients were administered 100% oxygen at a pressure of 2.5 atm. Results The group effect of total or partial resolution was observed in six patients. In one case, treatment was discontinued due to an increase in hematuria and the consequent suspicion of bladder tumor recurrence. While in and additional three cases, the treatment did not produce the desired result. Conclusions Treatment of hemorrhagic cystitis is a difficult therapeutic challenge. One possible method is the implementation of HBOT. In very difficult cases, HBO2 treatment appears to be effective in giving more than half of patients a chance of getting better. PMID:24578962

We aimed to identify patients with a chief complaint of hematuria who could safely avoid unnecessary radiation and instrumentation in the diagnosis of bladder cancer (BC), using automated urine flow cytometry to detect isomorphic red blood cells (RBCs) in urine. We acquired urine samples from 134 patients over the age of 35 years with a chief complaint of hematuria and a positive urine occult blood test or microhematuria. The data were analyzed using the UF-1000i (®) (Sysmex Co., Ltd., Kobe, Japan) automated urine flow cytometer to determine RBC morphology, which was classified as isomorphic or dysmorphic. The patients were divided into two groups (BC versus non-BC) for statistical analysis. Multivariate logistic regression analysis was used to determine the predictive value of flow cytometry versus urine cytology, the bladder tumor antigen test, occult blood in urine test, and microhematuria test. BC was confirmed in 26 of 134 patients (19.4 %). The area under the curve for RBC count using the automated urine flow cytometer was 0.94, representing the highest reference value obtained in this study. Isomorphic RBCs were detected in all patients in the BC group. On multivariate logistic regression analysis, only isomorphic RBC morphology was significantly predictive for BC (p < 0.001). Analytical parameters such as sensitivity, specificity, positive predictive value, and negative predictive value of isomorphic RBCs in urine were 100.0, 91.7, 74.3, and 100.0 %, respectively. Detection of urinary isomorphic RBCs using automated urine flow cytometry is a reliable method in the diagnosis of BC with hematuria.

Urinary retention: benefit of gradual bladder decompression - myth or truth? A randomized controlled trial.

Urinary retention is a common emergency requiring immediate catheterization. Gradual decompression (GD) of the extended bladder is believed to minimize the risk of complications such as bleeding or circulatory collapse, but to date it has not been compared with rapid decompression (RD) in controlled trials. Male patients presenting with urinary retention (n = 294) were randomized to rapid or gradual catheterization. For the latter, the transurethral catheter was clamped for 5 min after every 200-ml outflow until the bladder was completely empty. Patients were monitored for at least 30 min thereafter with regular checks of vital signs and presence of macroscopic hematuria. Of 294 patients, 142 (48.3%) were randomized to the GD and 152 (51.7%) to the RD group. Both groups showed no statistically significant difference with regard to age, anticoagulation treatment, catheter size and material, or volume retained. Hematuria occurred in 16 (11.3%) of the GD and 16 (10.5%) of the RD group; 6 patients in the former and 4 in the latter required further treatment. No circulatory collapse occurred. We noted a decrease in the previously raised blood pressure and heart rate in both groups, although without clinical significance. In this first randomized trial, no statistically significant difference was noted between gradual and rapid emptying of the bladder for urinary retention. Gradual emptying did not reduce the risk of hematuria or circulatory collapse. Therefore, there is no need to prefer gradual over rapid emptying, which is both easy and safe. © 2013 S.

Urinalysis in children and adolescents.

PubMed

Utsch, Boris; Klaus, Günter

2014-09-12

Urinalysis is the most commonly performed biochemical test in infancy and early childhood. The urine sample should be correctly obtained, age-specific aspects should be considered, and age-dependent reference values should be used. This review is based on a selective literature search in electronic databases, textbooks, and guidelines from Germany and abroad on the acquisition of urine samples and the performance of urinalysis in infancy and early childhood. The timing and mode of acquisition of the urine sample affect the assessment of hematuria, proteinuria, leukocyturia, nitrituria, and the uropathogenic bacterial colony count in the urine culture. Dipstick tests can be used for targeted screening for these features. The test results should be interpreted together with the findings of urine microscopy, the medical history, and the physical examination. Proteinuria should be quantified and differentiated; both of these things can be done either from collected urine or (especially in infants and young children) from a spontaneously voided urine sample, by determination of the protein/creatinine quotient. Orthostatic proteinuria in an adolescent requires no further evaluation or treatment. Hematuria should be characterized as either glomerular or non-glomerular erythrocyturia. Asymptomatic, isolated microhematuria in childhood is not uncommon and often transient; in the absence of a family history, it usually does not require an extensive work-up. Proteinuria combined with hematuria should arouse the suspicion of glomerulonephritis. Urinalysis in infancy and early childhood is a simple and informative diagnostic test as long as the urine sample has been obtained properly and the results are interpreted appropriately for this age group.

A 2-year-old domestic shorthair cat was presented with a history of hematuria, stranguria and intermittent urethral obstruction. Urine sediment showed hematuria, pyuria, and yellow-brown, amorphous and spherical crystals. Upon surgical correction of the obstructed urethra by perineal urethrostomy, many dark yellow to grey, irregular, gravel-like to millet grain-sized uroliths, consisting of 100% xanthine by crystallography were found. The urinary xanthine concentration was high. The cat subsequently developed bilateral nephroliths, recurrent urinary tract infection, and chronic kidney failure. Dietary management with a low-purine diet failed in part due to poor compliance, and the cat was euthanized at 6 years of age. Xanthinuria is rare inborn error of metabolism in cats and other species but should be considered as a differential diagnosis in cases of feline urolithiasis. No associated molecular genetic defect has been elucidated, and management of these cases is difficult. In the absence of calculi for analysis, measuring urinary xanthine concentration can help in diagnosing this metabolic defect. PMID:26478726

Nephron sparing by partial median nephrectomy for treatment of renal hemangioma in a dog.

1996-04-15

A 6-year-old neutered male Golden Retriever was admitted for evaluation of intermittent hematuria of 2 months' duration. A 3-cm heterogeneous mass causing distortion of the caudomedial aspect of the left kidney was detected via ultrasonography. Histologic examination of a renal tissue sample obtained by ultrasound-guided biopsy revealed a telangiectatic vascular plexus of unknown origin. Low glomerular filtration rate was identified by a modified exogenous creatinine clearance test. Excretory urography revealed a filling defect in the medial aspect of the caudal pole of the kidney, near the hilus. Because total renal function was low, a decision was made to perform nephron-sparing surgery involving resection of centrally located renal parenchymal and pelvic tissue by en bloc resection in the median plane, instead of radical nephrectomy. After surgery, the hematuria resolved and further decrease in renal function was not evident. Nephron-sparing surgery is a viable option for dogs with compromised renal function when there is concern that radical nephrectomy may precipitate uremia.

Transitional cell carcinomas (TCC) of the urinary bladder were diagnosed in four related fishing cats (Prionailurus viverrinus). The major clinical sign in each case was persistent hematuria unresponsive to medical therapy. Cystotomy and biopsy provided an antemortem diagnosis in three of the fishing cats before euthanasia because of progression of clinical signs. The diagnosis was made in the fourth cat after euthanasia because of renal failure. Hematuria improved temporarily in one of the cats diagnosed antemortem and treated with piroxicam and carboplatin. Attempts to isolate a herpesvirus in two of the cats failed. Histopathologic appearance of the TCC was similar to that described for other species. TCC metastasis to the lungs was noted at necropsy in one cat; metastatic disease was not noted in the other fishing cats on gross or histopathologic examination. TCC of the urinary bladder appears to be more prevalent in fishing cats than in other species of domestic or nondomestic felids.

To identify randomized controlled trials comparing the use of hydrophilic and nonhydrophilic catheters for intermittent catheterization (IC) in patients with spinal cord injury (SCI), and to perform a meta-analysis evaluating the occurrence of hematuria and urinary tract infection (UTI). We searched the following electronic databases to identify studies: EMBASE (1991 to August 2011), PubMed (1991 to August 2011), Cochrane Library (no date restriction), China National Knowledge Infrastructure (no date restriction), and the Chinese Biomedical Literature Database (no date restriction). Randomized controlled trials, parallel-control, crossover-control, and prospective cohort studies that assessed morbidity associated with the use of hydrophilic catheters and nonhydrophilic catheters in patients after SCI were included. Data extraction was performed using standardized forms of the Cochrane Collaboration. Methodologic quality was independently assessed by 2 reviewers using the Downs and Black instrument. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were calculated for dichotomous data. Five studies involving 508 subjects; 462 subjects completed the study and were included in this meta-analysis. There was a significantly lower incidence (OR=.36; 95% CI, 24%-54%; P<.0001) of reported UTIs in the hydrophilic-treated group compared with the nonhydrophilic-treated group. Hematuria was also reported significantly less in the hydrophilic catheter group than in the nonhydrophilic catheter group (OR=.57; 95% CI, 35%-92%; P=.001). This meta-analysis found UTIs and hematuria less frequently associated with the use of hydrophilic-coated catheters for IC in patients with SCI. These findings support the use of hydrophilic catheters in this patient population. Copyright © 2013 American Congress of Rehabilitation Medicine. Published by Elsevier Inc. All rights reserved.

Lower urinary tract operations are being increasingly performed in elderly patients, in whom aspirin intake is common for preventing cardiovascular disease. We determined the safety of early aspirin re-initiation after lower urinary tract surgeries. A randomized, open label clinical trial was done. The study cohort included patients referred for transurethral prostatectomy, open prostatectomy and transurethral resection of bladder tumor while receiving aspirin prophylaxis. After controlling for surgical modality patients were randomized into 2 arms, including aspirin treatment initiation 24 hours after discontinuing of bladder irrigation (early treatment group) and aspirin treatment initiation 3 weeks after surgery (late treatment group). Primary end points were pre-discharge hematuria necessitating the restoration of bladder irrigation or the cessation of aspirin treatment and late hematuria treated in an urgent care setting, requiring hospital admission or compelling the cessation of aspirin treatment. A total of 120 patients were enrolled, including 60 per treatment group. There were no significant differences between the groups in surgery related factors that could have affected postoperative bleeding. Primary end points were attained by 16 of the 120 patients (13.6%), including 10 of the 60 (16.7%) in the early treatment group and 6 (10%) in the late treatment group (p = 0.28). Time to catheter removal and persistent hematuria duration were similar in the 2 groups. Cardiovascular morbidity was noted in 3 of 120 patients, of whom all were assigned to the early treatment group. Early aspirin initiation after lower urinary tract surgeries does not appear to carry an increased risk of postoperative bleeding. Thus, it may be considered in patients at high risk for cardiovascular morbidity.

Ten percent to 15% of urinary catheterizations involve complications. New techniques to reduce risks and pain are indicated. This study examines the feasibility and safety of male urinary catheterization by nursing personnel using a visually guided device in a clinical setting. The device, a 0.6-mm fiber-optic bundle inside a 14F triple-lumen flexible urinary catheter with a lubricious coating, irrigation port, and angled tip, connects to a camera, allowing real-time viewing of progress on a color monitor. Two emergency nurses were trained to use the device. Male patients 18 years or older presenting to the emergency department with an indication for urinary catheterization using a standard Foley or Coudé catheter were eligible to participate in the study. Exclusion criteria were a current suprapubic tube or gross hematuria prior to the procedure. Twenty-five patients were enrolled. Data collected included success of placement, total procedure time, pre-procedure pain and maximum pain during the procedure, gross hematuria, abnormalities or injuries identified if catheterization failed, occurrence of and reason for equipment failures, and number of passes required for placement. All catheters were successfully placed. The median number of passes required was 1. For all but one patient, procedure time was ≤ 17 minutes. A median increase in pain scores of 1 point from baseline to the maximum was reported. Gross hematuria was observed in 2 patients. The success rate for placement of a Foley catheter with the visually guided device was 100%, indicating its safety, accuracy, and feasibility in a clinical setting. Minimal pain was associated with the procedure. Copyright © 2013 Emergency Nurses Association. Published by Mosby, Inc. All rights reserved.

Purpose: To fit urinary toxicity data of patients treated with postprostatectomy radiation therapy with the linear quadratic (LQ) model with/without introducing a time factor. Methods and Materials: Between 1993 and 2010, 1176 patients were treated with conventional fractionation (1.8 Gy per fraction, median 70.2 Gy, n=929) or hypofractionation (2.35-2.90 Gy per fraction, n=247). Data referred to 2004-2010 (when all schemes were in use, n=563; conventional fractionation: 316; hypofractionation: 247) were fitted as a logit function of biological equivalent dose (BED), according to the LQ model with/without including a time factor γ (fixing α/β = 5 Gy). The 3-year risks of severe urethral stenosis, incontinence, and hematuriamore » were considered as endpoints. Best-fit parameters were derived, and the resulting BEDs were taken in multivariable backward logistic models, including relevant clinical variables, considering the whole population. Results: The 3-year incidences of severe stenosis, incontinence, and hematuria were, respectively, 6.6%, 4.8%, and 3.3% in the group treated in 2004-2010. The best-fitted α/β values were 0.81 Gy and 0.74 Gy for incontinence and hematuria, respectively, with the classic LQ formula. When fixing α/β = 5 Gy, best-fit values for γ were, respectively, 0.66 Gy/d and 0.85 Gy/d. Sensitivity analyses showed reasonable values for γ (0.6-1.0 Gy/d), with comparable goodness of fit for α/β values between 3.5 and 6.5 Gy. Likelihood ratio tests showed that the fits with/without including γ were equivalent. The resulting multivariable backward logistic models in the whole population included BED, pT4, and use of antihypertensives (area under the curve [AUC] = 0.72) for incontinence and BED, pT4, and year of surgery (AUC = 0.80) for hematuria. Stenosis data could not be fitted: a 4-variable model including only clinical factors (acute urinary toxicity, pT4, year of surgery, and use of antihypertensives) was

In allogeneic bone marrow transplanted (BMT) patients BK virus (BKV) reactivation has been associated with haemorrhagic cystitis (HC). However, it is far from obvious which patients will develop HC, since BKV, a human polyomavirus, is ubiquitious and infects children at an early age. To investigate if a primary BKV infection, as such or possibly due to transmission of BKV by the marrow graft during BMT, was correlated to the development of HC, 45 children were followed for possible BKV seroconversion and development of HC at different time points after BMT. Serum samples were collected from the 45 allogeneic BMT children and their donors before transplantation, and from the patients at 3, 6 and 12 months after BMT. These sera were analysed for the presence of specific antibodies towards BKV by hemagglutination inhibition (HAI) and by IgG- and IgM-class specific enzyme linked immunosorbent (ELISA) assays. Twelve of the 45 BMT children had a documented episode of HC or hematuria. All patients and 98% of the donors were HAI positive before BMT, while with ELISA 87% of the patients and 84% of the donors were positive. Moreover, most HC and hematuria children (11/12) were seropositive with both assays before BMT, making it impossible to investigate possible BKV transmission through the bone marrow graft during BMT by serology. Still, serological changes such as ELISA seroconversion, IgM antibodies and/or HAI titer increases were significantly (p=0.016) more common in patients with HC (58%) than without HC (24%), but these changes occured mainly after HC symptomatology had already resolved. However, there was a near significant difference (p=0.053) in BKV seroprevalence by ELISA among the donors of patients with HC or hematuria (67%) as compared to the donors (91%) of patients without HC.

Abstract Background: Renal anastomosing hemangioma (RAH) is an extremely rare benign vascular tumor first described in 2009. Making this diagnosis is fraught with challenges. Radiologically they share features consistent with renal cell carcinomas (RCCs). Their vascular nature poses risks if considering preoperative biopsy and histologically they share characteristics akin to angiosarcomas. The few reports published in the literature suggest presentation with hematuria, flank pain, and polycythemia although the majority are diagnosed at postnephrectomy histologic examination. This case represents the first metachronous RAH in the literature, and is the first RAH presenting with severe hemorrhage. Case Presentation: A 62-year-old woman of Albanian heritage presented to urology with visible hematuria and positive urine cytology. Three years before this presentation, she had undergone an elective radical right-sided nephrectomy for a suspected RCC detected on magnetic resonance imaging, which proved to be an RAH after postoperative histologic examination of the specimen. The patient was investigated with cystoscopy and ureteroscopy for this new hematuria presentation, both of which were unremarkable. Fourteen hours post ureteroscopy, the patient became severely hypotensive and developed acute kidney injury. A CT scan indicated a large left-sided renal subcapsular and retroperitoneal hematoma that was actively bleeding. The patient was hemodynamically unstable and, therefore, required an emergency open left-sided nephrectomy, rendering her anephric and dialysis dependent. Postoperative histologic examination proved that the left kidney also contained an RAH. Conclusion: The anastomosing hemangioma is an important subtype to differentiate from angiosarcoma before and after a nephrectomy. Urologists should carefully consider invasive tests in patients with previously diagnosed vascular lesions as there may be an increased risk of bleeding. Patients with a previously

This study tests the hypothesis that combined melatonin and adipose-derived mesenchymal stem cell (ADMSC, 1.2 × 10(6) given intravenously) treatment offer superior protection against cyclophosphamide (CYP 150 mg/kg)-induced acute interstitial cystitis (AIC) in rats. Male adult Sprague-Dawley rats were treated as follows: sham controls, AIC alone, AIC + melatonin, AIC + ADMSC, and AIC + melatonin +ADMSC. When melatonin was used, it was given as follows: 20 mg/kg at 30 min after CYP and 50 mg/kg at 6 and 18 hr after CYP. Twenty-four-hour urine volume, urine albumin level, and severity of hematuria were highest in AIC rats and lowest in the controls; likewise urine volume was higher in AIC + melatonin rats than in AIC + ADMSC and AIC + melatonin + ADMSC treated rats; in all cases, P < 0.001. The numbers of CD14+, CD74+, CD68+, MIP+, Cox-2+, substance P+, cells and protein expression of IL-6, IL-12, RANTES, TNF-α, NF-κB, MMP-9, iNOS (i.e. inflammatory biomarkers), glycosaminoglycan level, expression of oxidized protein, and protein expression of reactive oxygen species (NOX-1, NOX-2, NOX-4) in the bladder tissue exhibited an identical pattern compared with that of hematuria among the five groups (all P < 0.0001). The integrity of epithelial layer and area of collagen deposition displayed an opposite pattern compared to that of hematuria among all groups (P < 0.0001). The cellular expressions of antioxidants (GR, GPx, HO-1, NQO 1) showed a significant progressive increase form controls to AIC + melatonin + ADMSC (all P < 0.0001). Combined regimen of melatonin and ADMSC was superior to either alone in protecting against CYP-induced AIC. © 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

To determine the time to bladder cancer diagnosis from initial infection-like symptoms and its impact on cancer outcomes. Using Surveillance, Epidemiology and End Results-Medicare, we designed a retrospective cohort study identifying beneficiaries aged ≥ 66 years diagnosed with bladder cancer from 2007 to 2009. Patients were required to have a hematuria or urinary tract infection claim within 1 year of bladder cancer diagnosis (n = 21 216), and have 2 years of prior Medicare data (n = 18 956) without any precedent hematuria, bladder cancer or urinary tract infection claims (n = 12 195). The number of days to bladder cancer diagnosis was measured, as well as the impact of sex and presenting symptom on time to diagnosis, pathology, and oncological outcomes. The mean time to bladder cancer diagnosis was 72.2 days in women versus 58.9 days in men (P < 0.001). A logistic regression model identified the greatest predictors of ≥ pT2 pathology were both women (odds ratio 2.08, 95% confidence interval 1.70-2.55) and men (odds ratio 1.71, 95% confidence interval 1.49-1.97) presenting with urinary tract infection. Cox proportional hazards analysis identified an increased risk of mortality from bladder cancer and all causes in women presenting with urinary tract infection (hazard ratio 1.37, 95% confidence interval 1.10-1.71, and hazard ratio 1.47, 95% confidence interval 1.28-1.69) compared with women with hematuria. Women have a longer interval from urinary tract infection to diagnosis of bladder cancer. Urinary tract infection presentation can adversely affect time to diagnosis, pathology and survival. Time to diagnosis seems not to be an independent predictor of bladder cancer outcomes. © 2015 The Japanese Urological Association.

Alport syndrome is a genetic condition that results in hematuria, progressive renal impairment, hearing loss, and occasionally lenticonus and retinopathy. Approximately 80% of Alport syndrome cases are caused by X-linked mutations in the COL4A5 gene encoding type IV collagen. The objective of this study was to define the SNP profiles for COL4A5 in patients with hereditary nephritis and hematuria. For this, we examined four subjects from one Kazakh family clinically affected with X-linked Alport syndrome due to COL4A5 gene mutations. All 51 exons of the COL4A5 gene were screened by linkage analysis and direct DNA sequencing, resulting in the identification of a novel mutation (G641E) in exon 25. The mutation was found only in two affected family individuals but was not present in healthy family members or 200 unrelated healthy controls. This result demonstrates that this novel mutation is pathogenic and has meaningful implications for the diagnosis of patients with Alport syndrome. PMID:26168235

Alport syndrome is due to mutations in one of the genes encoding (α3,4,5) type IV collagen resulting in defective type IV collagen, a key component of the glomerular basement membrane (GBM). The GBM is initially thin, and with ongoing remodeling, develops a thickened basket-woven appearance. We report a unique case of a 9-year-old boy who was biopsied for hematuria and proteinuria, diagnosed as IgA nephropathy, with normal GBM appearance and thickness. Due to a family history of hematuria and chronic kidney disease, he subsequently underwent genetic evaluation and a mutation of α3 type IV collagen (COL4A3) was detected. Additional studies of the initial biopsy demonstrated abnormal type IV collagen immunostaining. A repeat biopsy 4years later showed characteristic glomerular basement membrane morphology of Alport syndrome, and scarring consistent with sequelae of IgA nephropathy. This is the first description of this unusual transition from an initial normal appearance of the glomerular basement membrane to the classic Alport phenotype. Copyright © 2018.

The therapeutic efficacy of immunosuppressants for treating rapidly progressive glomerulonephritis (RPGN) with crescent formation remains controversial. SCG/Kj mice spontaneously develop RPGN-like symptoms, characteristic of crescentic glomerulonephritis and systemic small vessel vasculitis, associated with the presence of anti-neutrophil cytoplasmic antibodies (ANCA). We evaluated the "ameliorative", not prophylactic, effects of immunosuppressive agents, deoxyspergualin (DSG), cyclophosphamide (CYC) and prednisolone (PDN), on RPGN in these mice. DSG at intraperitoneal doses of 3 and 6 mg/kg, CYC at an oral dose of 12 mg/kg, or PDN at an intraperitoneal dose of 120 mg/kg was administered once a day for 21 days to female mice "at the onset of hematuria". A set of control SCG/Kj mice received only saline injections. DSG and CYC significantly prolonged survival, improved the proteinuria, hematuria and hyperuremia, and decreased the serum level of myeloperoxidase-ANCA. Moreover, DSG significantly suppressed the formation of crescents in glomeruli. PDN failed to affect any of the parameters. DSG might be useful for inducing remission in crescentic glomerulonephritis involved in RPGN.

Squamous cell carcinoma of the bladder mimicking interstitial cystitis and voiding dysfunction.

Squamous cell carcinoma (SCC) of the bladder is a relatively uncommon cause of bladder cancer accounting for <5% of bladder tumors in the western countries. SCC has a slight male predominance and tends to occur in the seventh decade of life. The main presenting symptom of SCC is hematuria, and development of this tumor in the western world is associated most closely with chronic indwelling catheters and spinal cord injuries. A 39-year-old Caucasian female presented with bladder and lower abdominal pain, urinary frequency, and nocturia which was originally believed to be interstitial cystitis (IC) but was later diagnosed as SCC of the bladder. Presentation of SCC without hematuria is an uncommon presentation, but the absence of this symptom should not lead a practitioner to exclude the diagnosis of SCC. This case is being reported in an attempt to explain the delay and difficulty of diagnosis. Background on the risk factors for SCC of the bladder and the typical presenting symptoms of bladder SCC and IC are also reviewed.

Background Recent data emphasize that thin basement membrane nephropathy (TBMN) should not be viewed as a form of benign familial hematuria since chronic renal failure (CRF) and even end-stage renal disease (ESRD), is a possible development for a subset of patients on long-term follow-up, through the onset of focal and segmental glomerulosclerosis (FSGS). We hypothesize that genetic modifiers may explain this variability of symptoms. Methods We looked in silico for potentially deleterious functional SNPs, using very strict criteria, in all the genes significantly expressed in the slit diaphragm (SD). Two variants were genotyped in a cohort of well-studied adult TBMN patients from 19 Greek-Cypriot families, with a homogeneous genetic background. Patients were categorized as “Severe” or “Mild”, based on the presence or not of proteinuria, CRF and ESRD. A larger pooled cohort (HEMATURIA) of 524 patients, including IgA nephropathy patients, was used for verification. Additionally, three large general population cohorts [Framingham Heart Study (FHS), KORAF4 and SAPHIR] were used to investigate if the NEPH3-V353M variant has any renal effect in the general population. Results and conclusions Genotyping for two high-scored variants in 103 TBMN adult patients with founder mutations who were classified as mildly or severely affected, pointed to an association with variant NEPH3-V353M (filtrin). This promising result prompted testing in the larger pooled cohort (HEMATURIA), indicating an association of the 353M variant with disease severity under the dominant model (p = 3.0x10-3, OR = 6.64 adjusting for gender/age; allelic association: p = 4.2x10-3 adjusting for patients’ kinships). Subsequently, genotyping 6,531 subjects of the Framingham Heart Study (FHS) revealed an association of the homozygous 353M/M genotype with microalbuminuria (p = 1.0x10-3). Two further general population cohorts, KORAF4 and SAPHIR confirmed the association, and a meta-analysis of all

Renal vein thrombosis mimicking urinary calculus: a dilemma of diagnosis.

Renal vein thrombosis (RVT) with flank pain, and hematuria, is often mistaken with renal colic originating from ureteric or renal calculus. Especially in young and otherwise healthy patients, clinicians are easily misled by clinical presentation and calcified RVT. A 38-year-old woman presented with flank pain and hematuria suggestive of renal calculus on ultrasound. She underwent extracorporeal shock wave lithotripsy that failed, leading to the recommendation that percutaneous lithotomy was necessary to remove the renal calculus. In preoperative view of the unusual shape of the calculus without hydronephrosis, noncontrast computed tomography was taken and demonstrated left ureteric calculus. However computed tomography angiography revealed, to our surprise, a calcified RVT that was initially thought to be a urinary calculus. This case shows that a calcified RVT might mimic a urinary calculus on conventional ultrasonography and ureteric calculus on noncontrast computed tomography. Subsequent computed tomography angiography disclosed that a calcified RVT caused the imaging findings, thus creating a potentially dangerous clinical pitfall. Hence, it is suggested that the possibility of a RVT needs to be considered in the differential diagnosis whenever one detects an uncommon shape for a urinary calculus.

Eosinophilic cystitis with recurrent urinary retention: case report.

Eosinophilic cystitis is a rare inflammatory disease of the bladder whose origin, pathogenesis, and treatment are unknown. Frequency, dysuria, and hematuria are frequent symptoms. Here, we report a rare occurrence of recurrent urinary retention and repetitive catheterization. A 67-year-old male presented with acute urinary retention and intermittent gross hematuria of 2 weeks duration. Urethral catheterization followed by a trial without catheter, was successful. Complete blood count showed presence of eosinophils (eosinophilia) and computed tomography of kidneys, ureter and bladder with contrast showed thickened bladder wall and small prostate. Cystoscopy revealed an erythematous lesion over the anterior wall. The rest of the mucosa was normal. Transurethral biopsies of the lesion were performed and histologic examination showed features of eosinophilic cystitis. Despite multiple medication regimens containing corticosteroids and antihistamines, he presented with recurrent urinary retention, approximately once every month. After 6 months, he was started on bethanechol, which led to no catheterization for up to 2 years. To the best of our knowledge, this is the first report on the successful use of bethanechol as a treatment for eosinophilic cystitis with recurrent urinary retention.

The overall success rate in 77 patients was 78%. All patients had a preoperative intravenous urogram or a retrograde pyelogram, but none had vascular imaging studies. Acucise endopyelotomy consisted of a posterolateral incision of the UPJ and placement of an endopyelotomy or double-J stent. Foley catheter placement at the end of the procedure demonstrated significant gross hematuria in three patients (4%). All three remained hemodynamically stable but with significant drops in postprocedure hemoglobin levels, which necessitated blood transfusion. Aggressive management included angiographic studies and embolization of lower-pole branching arteries in two patients (3%). One patient stopped bleeding after being given two units of blood. None of the patients required an open exploratory procedure. Although the risk of vascular injury is low with Acucise endopyelotomy, prolonged postoperative gross hematuria does mandate investigation and observation. Angiographic embolization appears to be the therapeutic modality of choice for patients with hemorrhagic complications after an Acucise endopyelotomy.

This study aimed to develop a tool in identifying traumatized children at low risk of pelvic fracture and to determine the sensitivity of this low-risk model for pelvic fractures. We hypothesized that the proportion of children without predictors with pelvic fracture is less than 1%. This is a retrospective trauma registry analysis of previously healthy children 1 year to 17 years old presenting to the pediatric emergency department with blunt trauma. Postulated predictors of pelvic fracture on radiograph or computed tomography included pain/abnormal examination result of the pelvis/hip, femur deformity, hematuria, abdominal pain/tenderness, Glasgow Coma Scale (GCS) score of 13 or lower, and hemodynamic instability. We used multivariable logistic regression to identify independent predictors of fracture. Of 1,121 eligible patients (mean [SD] age, 8.5 [4.6] years), 87 (7.8%) had pelvic fracture. Independent predictors included pain/abnormal examination result of the pelvis/hip (odds ratio [OR], 16.7; 95% confidence interval [CI], 9.6-29.1), hematuria (OR, 6.6; 95% CI, 3.0-14.6), femoral deformity (OR, 5.9; 95% CI, 3.1-11.3), GCS score of 13 or lower (OR, 2.4; 95% CI, 1.3-4.3), and hemodynamic instability (OR, 3.4; 95% CI, 1.7-6.9). One of 590 children (0.2%; 95% CI, 0-0.5%) without predictors had pelvic fractures versus 86 (16.2%) of 531 in those with one or more predictors (OR, 119; 95% CI, 16.6-833). One of 87 children with pelvic fractures had no predictors (1.1%; 95% CI, 0-3%). When assuming a 100% radiography rate, this tool saves 53% pelvic radiographs. Children with multiple blunt trauma without pain/abnormal examination result of the pelvis/hip, femur deformity, hematuria, abdominal pain/tenderness, GCS score of 13 or lower, or hemodynamic instability constitute a low-risk population for pelvic fracture, with less than 0.5% risk rate. This population does not require routine pelvic imaging. Therapeutic study, level IV.

Nephrotic syndrome in children is a clinical manifestation of different histopathological subtypes. There is a paucity of recent large studies dealing with the histopathological spectrum from developing countries. A prospective study was performed from January 1990 to December 2000 at our center, involving 600 children (with age of onset up to 16 years) with idiopathic nephrotic syndrome (INS). The objectives were: (1) to study the histopathological distribution of different subtypes of INS and (2) to compare the clinical and biochemical parameters at the time of diagnosis of minimal change disease (MCD) with non-MCD subtypes. For the purpose of this study we analyzed only those children with INS who underwent biopsies. The study group included 290 children in which adequate biopsy reports were available. There were 213 males and 77 females. Mean age at onset of INS was 7.9+5.1 years. Facial edema was found in 286 (98.6%), microhematuria in 120 (41.3%), gross hematuria in 7 (2.5%), and hypertension in 77(26.8%) patients. All patients of the study group were seronegative for HBsAg and HIV. Focal and segmental glomerulosclerosis (FSGS) was the most common histopathological subtype, occurring in 110 of 290 children (38%). Other subtypes included MCD in 95 children (32%), membranoproliferative glomerulonephritis (MPGN) in 44 children (15%), mesangioproliferative glomerulonephritis in 33 children (11%), membranous glomerulonephritis in 5 children (2%), and diffuse mesangial sclerosis in 3 children (1%). In children under 8 years of age, MCD was the most common entity, whereas FSGS predominated in children with age at onset greater than 8 years. The age at onset of nephrotic syndrome was significantly higher in the non-MCD group than the MCD group. The incidence of hypertension, microhematuria, and gross hematuria was significantly lower in the MCD group. MCD remains the most common histopathological subtype in Indian children with INS and onset under 8 years of age. The

To introduce a method of retrograde ureteric catheter placement via flexible cystoscope , and to evaluate the feasibility and safety of this method. 112 patients, 62 males and 50 females undergoing retrograde ureteropyelography by 2 same physicians in cooperation were randomly divided into two equal groups with 31 males and 25 females each: one group via flexible cystoscope and the other group via rigid cystoscope. The catheterizing time, visual analogue scale (VAS) pain score, gross hematuria rate, and fever rate were compared between these 2 groups. Fifty-five patients underwent ureteric catheter placement successfully via flexible cystoscope (98%, 55/56), while 53 cases were technically successful by rigid cystoscope (95%, 53/56). The inserting time in women patients of the flexible cystoscopy group was (7.6 +/- 1.8) min, significantly shorter than that of the men [(8.0 +/- 1.8) min, P < 0.05]. The inserting time in women patients of the rigid cystoscopy group was (7.4 +/- 1.5) min, significantly shorter than that of the men [(8.2 +/- 1.2) min, P < 0.05]. However, there were not significant differences in the inserting times in both men and women between these 2 groups (both P > 0.05). The VAS pain scores in men and women of the flexible cystoscope group were 3. 5 and 2. 3 respectively, both significantly lower than those of the rigid cystoscopy group (7.2 and 3.3 respectively, both P < 0.05). The gross hematuria rate of the flexible cystoscope group was 8.6% (5/56), significantly lower than that of the rigid cystoscopy group (25.0%, 14/56, P < 0.05). Four patients had a fever after flexible cystoscopy while 6 cases did after rigid cystoscopy, however, without significant difference between these 2 groups (P > 0.05). Retrograde placement of ureteric catheter via flexible cystoscope is safe and reliable as rigid cystoscopy. Meanwhile, inserting ureteric catheter via flexible cystoscope causes the patients less pain and less chance of hematuria.

Hemangioperycytoma is a rare perivascular tumor that seldom involves the urogenital system. This tumor often appears with an unspecific clinical picture, and sometimes is associated with hematuria or hypertension. Diagnosis is based on a combination of histological and immunohistological findings. We report a case of a 52-year-old patient with renal hemangiopericytoma who underwent surgical treatment at our service. This report also includes a literature review on the subject.

Treatment of radiation-induced cystitis with hyperbaric oxygen

Weiss, J.P.; Boland, F.P.; Mori, H.

The effects of hyperbaric oxygen on radiation cystitis have been documented in 3 patients with radiation-induced hemorrhagic cystitis refractory to conventional therapy. Cessation of gross hematuria and reversal of cystoscopic bladder changes were seen in response to a series of hyperbaric oxygen treatments of 2 atmosphere absolute pressure for 2 hours. To our knowledge this is the first report of cystoscopically documented healing of radiation-induced bladder injury.

Blunt injuries of the renal vascular pedicle occur infrequently. The experience with fourteen cases of blunt renal vascular trauma is presented. Most patients were injured in motor vehicle accidents. The diagnosis was made immediately after admission in 6 patients, delayed in 5, and at autopsy in 3. Most patients presented with gross or microscopic hematuria. The diagnosis of renal vascular injury was suggested by IVP in most instances. Surgical management was used in the 6 patients in whom the immediate diagnosis of renal pedicle injury was made; primary vascular repair was carried out in 4 patients and nephrectomy in two. Conservative management was used in 4 of the 5 patients with delayed diagnosis, and nephrectomy was required in the fifth. Three patients received no treatment as two were dead on arrival and one die during laparotomy. Seven patients died (50%). One of the 7 survivors has a functioning kidney following repair of a renal vein laceration. Three patients with devascularized kidneys have been followed long term and have not developed hypertension. An IVP should be mandatory following severe blunt trauma, especially when hematuria is present. Renal arteriography is indicated with distortion of calyces, extravasation or nonfunction seen on IVP and allows a definitive diagnosis of renal vessel injury to be made. PMID:1190872

The use of motivational interviewing (MI) when the goals of patient and physician are not aligned is examined. A clinical example is presented of a patient who, partly due to anxiety and fear, wants to opt out of further evaluation of his hematuria while the physician believes that the patient must follow up on the finding of hematuria. As patients struggle in making decisions about their medical care, physician interactions can become strained and medical care may become compromised. Physicians sometimes rely on their authority within the doctor-patient relationship to assist patients in making decisions. These methods may be ineffective when there is a conflict in motivations or goals, such as with patient ambivalence and resistance. Furthermore, the values of patient autonomy may conflict with the values of beneficence. A patient simulation exercise is used to demonstrate the value of MI in addressing the motivations of a medical patient when autonomy is difficult to realize because of a high level of resistance to change due to fear. The salience of MI in supporting the value of patient autonomy without giving up the value of beneficence is discussed by providing a method of evaluating the patient's best interests by psychotherapeutically addressing his anxious, fear-based ambivalence.

To describe a cheap, minimally painful and widely usable method for retrieving ureteral stents by using an ureteroscope. Sixty-seven patients with ureteral stents were enrolled in this study. The patients were randomized into a cystoscopic (35 patients) and a ureteroscopic (32 patients) group. All stents were retrieved by a flexible cystoscope in the first group and by a ureteroscope in the second group under local anesthesia. Patients in each group were assessed for stented time, stent side, cause of stent placement, operative time, peroperative pain, postoperative pain, irritative voiding symptoms and hematuria. Also costs of instruments were calculated. Stents were successfully retrieved in 67 patients. There were no statistical differences in the two groups regarding patient gender and age or stent side, operative time, stented time, mean operative pain score, irritative voiding symptom scores and hematuria. Total selling price was USD 20.399 for flexible instruments and USD 10.516 for rigid ones. Total maintenance price was higher in flexible instruments than in the rigid ones (USD 197.8 and 51.7 per use, respectively). Ureteroscopic stent retrieval is a minimally painful, safe and highly tolerable method under local anesthesia as well as flexible cystoscopic retrieval. Also, it is a cheap and widely usable method.

Goswami, A K; Mahajan, R K; Nath, R; Sharma, S K

1993-02-01

A prospective study was done to evaluate the efficacy and safety of intravesical instillation of 1% alum solution in 12 cases of hematuria of vesical origin, uncontrolled by saline irrigation for 24 hours via a 3-way Foley catheter. There were 10 cases of transitional cell carcinoma and 2 of radiation cystitis. Complete response was noted in 6 patients and a partial response in 4. Local side effects included suprapubic pain and vesical tenesmus, which were controlled by antispasmodic and/or analgesic drugs. Transient low grade pyrexia (maximum up to 38.2C) was noted in 4 patients. Among the other various clinical and biochemical parameters, serum aluminum level and prothrombin time showed statistically highly significant changes. Serum aluminum increased from an average baseline value of 1.68 to 3.36 mumol./l. without clinical evidence of aluminum toxicity and with levels well below the recommended safe limit. Prothrombin time increased parallel with the increase in serum aluminum level to a maximum of 1 1/2 times the control. Prothrombin values, therefore, can be used clinically, since they are readily obtainable whereas serum aluminum levels are not. Vesical irrigation with 1% alum solution is a safe method to control hematuria of vesical origin in properly selected cases.

A young female presented with an acute abdominal pain and oliguria for 1 week following normal vaginal delivery. No history of hematuria was present. Patient was having lochia rubra. Sealed uterine rupture was suspected clinically. Initial ultrasound of the patient showed distended urinary bladder containing Foley catheter ballon with clamping of Foley catheter and particulate ascites. Abdominal paracentesis revealed hemorrhagic fluid. Contrast-enhanced computed tomography of abdomen revealed ascites, distended urinary bladder and no extraluminal contrast extravasation in delayed scan. As patient condition deteriorated, repeat ultrasound guided abdominal paracentesis was done which revealed transudative peritoneal collection with distended bladder. Cystoscopy revealed urinary bladder ruptures with exudate sealing the rupture site. Exploratory laparotomy was done and a diagnosis of extraperitoneal bladder rupture was confirmed. The rent was repaired in layers. She was put on continuous bladder drainage for 3 weeks followed by bladder training. It presented in a unique way as there was hemorrhagic peritoneal tap, no macroscopic hematuria and urinary bladder was distended in spite of urinary bladder wall rupture which delayed the diagnosis and treatment. Complete emptying of urinary bladder before second stage of labor and during postpartum period with perineal repair is mandatory to prevent urinary bladder rupture. PMID:26985426

2009-09-01

Left renal vein division and ligation (LRVDAL) is performed to facilitate complex abdominal aortic surgery. Surgeons restore continuity of the vein due to concern that ligation could cause renal compromise or hematuria. However, we report the short and long-term safety of left renal vein division and ligation. Between 1992 and 2007, we divided the left renal vein in 56 patients (40 males, 16 females) ages 57 to 84 (average 74-years-old) who were treated for aortic occlusive disease (9) or abdominal aortic aneurysm (47). Patients requiring concomitant renal artery reconstruction were excluded from this review. Suprarenal cross-clamp was used in 51 patients with temporary vessel-loop control of the renal arteries. Creatinine (Cr) and glomerular filtration rates (eGFR) were measured pre-, post-, and long-term after surgery. Outpatient records of all patients that had survived more than 12 months were also reviewed in order to evaluate the late effects on renal function or symptoms possibly related to LRVDAL. Median procedure duration was 157 (61-375) minutes. Median cross-clamp time was 16 (10-45) minutes. Median intensive care unit (ICU) and hospital length of stays were 2 (1-11) days and 7 (4-58) days, respectively. There were no deaths. There were no complications directly related to renal vein ligation. Hematuria, seen in 2 patients, was a result of traumatic insertion of a Foley catheter. Median pre-op and discharge Cr levels were 1.1 mg/dL (0.7-2.4 mg/dL) and 1.1 mg/dL (0.6-2.1 mg/dL), respectively (P < .5). Median change in Cr was 0.0 mg/dL and only increased in 14 patients (maximum increase 0.9 mg/dL). Median pre-op and discharge eGFR was 61 mL/minute (28-137 mL/minute/1.73 m2) and 67 mL/minute (32-138 mL/minute/1.73 m2), respectively (P < .5). Cr and eGFR in the 2 patients with a Cr of >2.0 mg/dL remained unchanged post-op. Only 2 patients with a Cr of <2.0 mg/dL had a post-op Cr >2.0 mg/dL and both returned to normal by day 3 post-op.

Secondary bladder amyloidosis is an extremely rare disease, resulting from a chronic systematic inflammatory disorder associated with amyloid deposits. Although uncommon in Japan, familial Mediterranean fever (FMF) is a hereditary autoinflammatory disease characterized by recurrent episodes of fever of short duration and serositis and is frequently associated with systemic amyloidosis. Here, we present a case of a Japanese patient complaining of fever and macroscopic hematuria after a living donor renal transplantation. Consequently, he was diagnosed with secondary bladder amyloidosis with FMF. A 64-year-old Japanese male received a living ABO-incompatible kidney transplant from his wife. The postoperative clinical course was normal, and the patient was discharged 21 days after the transplantation with a serum creatinine level of 0.78 mg/dl. The patient frequently complained of general fatigue and fever of unknown origin. Six months later, the patient presented with continuous general fatigue, macroscopic hematuria, and fever. Cystoscopic examination of the bladder showed an edematous region with bleeding, and a transurethral biopsy revealed amyloid deposits. His wife stated that the patient had a recurrent high fever since the age of 40 years and that his younger brother was suspected to have a familial autoinflammatory syndrome; thus, the patient was also suspected to have a familial autoinflammatory syndrome. Based on his brother's medical history and the genetic tests, which showed a homozygous mutation (M694V/M694V) for the Mediterranean fever protein, he was diagnosed with FMF. Although colchicine treatment for FMF was planned, the patient had an untimely death due to heart failure. We re-evaluated the pathological findings of the various tissue biopsies obtained during the treatment after the renal transplantation. Immunohistochemistry revealed amyloid deposits in the bladder region, renal allograft, and myocardium and the condition was diagnosed as AA

Las inmunodeficiencias primarias (IDP) constituyen un grupo de enfermedades hereditarias que afectan el número y/o la función de los distintos componentes del sistema inmune. Su prevalencia es de 1:1000-2000 nacimientos. Comprenden defectos de la inmunidad adaptativa, defectos de la inmunidad innata, inmunodeficiencias con fenotipos característicos, trastornos de la regulación inmune, síndromes autoinflamatorios, defectos de los fagocitos y del sistema del complemento y defectos considerados fenocopias de IDP. La vacunación con vacunas inactivadas es segura y puede ser efectiva en muchas inmunodeficiencias; las vacunas vivas atenuadas pueden no ser protectoras en ciertas IDP o presentarse como enfermedad vacunal asociada a la inmunización, lo que conlleva una alta morbimortalidad. Con el objetivo de actualizar las recomendaciones de vacunas en pacientes con IDP, el Comité Nacional de Infectología y el Grupo de Trabajo de Inmunología trabajaron sobre las vacunas que podían indicarse a estos pacientes, convivientes y el equipo de salud.

Pathogenic molecular variants in the ADAR gene are a known cause of rare diseases, autosomal recessive Aicardi- Goutières syndrome type 6, severe infantile encephalopathy with intracranial calcifications and dominant dyschromatosis symmetrica hereditaria, demonstrated mainly in Asian adults. Recently, they have been also found in patients with nonsyndromic bilateral striatal necrosis accompanied by skin changes of the freckles-like type. Here, we present Polish siblings with acute onset and slowly progressive extrapyramidal syndrome with preserved intellectual abilities and basal ganglia changes found in MRI. A Leigh syndrome was considered for a long time as the most frequent cause of such lesions in children. Finally, two molecular variants in non-mitochondria-related ADAR gene c.3202+1G>A (p.?) and c.577C>G (p.Pro193Ala) were revealed by whole exome sequencing. We suggest that bilateral striatal necrosis should be always differentiated from LS to prevent the diagnosis delay. The striatal involvement accompanied by the presence of freckles-like skin changes should direct differential diagnosis to the ADAR gene mutations screening.

Urinary schistosomiasis is an infection caused by parasite, Schistosoma haematobium. Squistosomiasis is an endemic disease in Africa and Middle East. We are presenting a case of a young immigrant male from Mali that came to our clinic with hematuria and miccional irritative syndrome during a year. Parasitological study reported Schimosoma's eggs and ecography showed a possible vesical newformation. After RTU, anatomopatological study confirms the presence of a vesical esquistosomiasis. Now pacient is asyntomatic after he was treated with Praziquantel.

Spontaneous renal artery dissection (SRAD) is rare and presents a diagnostic and therapeutic challenge. We report a case of a 36-year-old man who had an SRAD-complicated renal infarction. The patient experienced severe unilateral flank pain. Enhanced abdominal computed axial tomography scan showed renal infarction, and urinalysis showed no hematuria. Selective renal angiography was essential to evaluate the extent of dissection and suitability for repair. The patient was treated with catheter-directed thrombolysis and frenal artery stenting.

We evaluated the effect of terazosin in the improvement of lower urinary tract symptoms and flank pain in patients with internal ureteral stents. In this double-blind randomized clinical trial, 73 patients with unilateral ureteral stone and hydroureteronephrosis who underwent insertion of an internal ureteral stent after transureteral lithotripsy (TUL) were randomized into two groups. 37 patients received terazosin 2 mg (once nightly) for 4 weeks and 36 patients received placebo for the same time duration. After 4 weeks, all patients were asked about the incidence of frequency, nocturia and urgency by an International Prostate Symptom Score (IPSS) questionnaire, flank pain and pain during urination by a visual analog scale (VAS) score, and hematuria. The mean VAS score was 2.21 in the terazosin group compared with 4.93 in the control group (p < 0.001). Nearly all the patients in the placebo group reported flank pain during urination but this was only reported in 54.5% of the patients in the terazosin group (p < 0.001). All criteria measured by the IPSS in the terazosin group were significantly lower than those in the placebo group (p = 0.0001). Administration of terazosin for patients with an internal ureteral stent relieved some stent-related symptoms such as flank pain, pain during voiding, frequency, nocturia and urgency, but had no effect on hematuria.

To study the clinical and pathological features of Alport syndrome in children. The clinical and histopathological data of 10 hospitalized children with Alport syndrome from February 2007 to February 2009 were retrospectively reviewed. There were 7 males and 3 females, with the age ranging from 2 years to 6 years and 7 months (mean 3 years and 2 months). Five of 10 cases had positive family history. X-linked dominant inheritance Alport syndrome was diagnosed in 8 cases, and autosomal recessive inheritance Alport syndrome in 2 cases. Recurrent gross hematuria was found in 5 cases, hematuria and proteinuria in 3 cases, massive proteinuria in 1 case, and nephritic syndrome in 1 case. Under the light microscope, 8 cases presented with mesangial proliferation glomerulonephritis, and 2 cases with focal segmental glomerulosclerosis. Immunofluorescence assay showed that all cases had IgM deposition in glomerulus. Only 1 case showed typical glomerular basement membrane (GBM) pathological changes. All cases showed abnormal alpha-chain distribution in renal collagen IV. The children with Alport syndrome have diverse clinical manifestations. Characteristic histopathological presentations could not be found under a light microscope, mesangial proliferation glomerulonephritis is the dominant pathological change, and IgM deposition in glomerulus is common. The GBM pathological change in children is not common. Immunofluorescence assay of alpha-chain in collagen IV is needed for the diagnosis of Alport syndrome.

The global burden of kidney disease is increasing, and several etiologies first begin in childhood. Risk factors for pediatric kidney disease are common in Africa, but data regarding its prevalence are lacking. We completed a systematic review of community-based studies describing the prevalence of proteinuria, hematuria, abnormal imaging, or kidney dysfunction among children in sub-Saharan Africa. Medline and Embase were searched. Five hundred twenty-three references were reviewed. Thirty-two references from 9 countries in sub-Saharan Africa were included in the qualitative synthesis. The degree of kidney damage and abnormal imaging varied widely: proteinuria 32.5% (2.2%-56.0%); hematuria 31.1% (0.6%-67.0%); hydronephrosis 11.3% (0.0%-38.0%), hydroureter 7.5% (0.0%-26.4%), major kidney abnormalities 0.1% (0.0%-0.8%). Serum creatinine was reported in four studies with insufficient detail to identify the prevalence renal dysfunction. A majority of the studies were performed in Schistosoma haematobium endemic areas. A lower prevalence of kidney disease was observed in the few studies from non-endemic areas. Published data on pediatric kidney disease in sub-Saharan Africa is highly variable and dependent on S. haematobium prevalence. More community-based studies are needed to describe the burden of pediatric kidney disease, particularly in regions where S. haematobium infection is non-endemic. PMID:25420180

Dioctophyma renale infection is found in a wide range of mammalian species, typically in temperate areas of the world. Here, we report for the first time, the parasitism of a domestic dog by D. renale in Hamedan, Iran, a mountainous cold region, lacking significant amounts of rainfall, high humidity and temperature. A 2.5 yr old male mixed breed dog was presented with a two months history of progressive hematuria and muscle weakness. Complete blood count and serum biochemistry were performed with results indicating impaired renal function. Urinalysis, showed hematuria as well as parasitic eggs, suggestive of D. renale infection. Urinary system ultrasonography revealed a hypoecogenic tubular structure in the right kidney. The animal was treated with fenbendazole (45 mg/kg, PO, QD - five days) and ivermectin (0.02 mg/kg, SC, single dose). One week later, repeated laboratory examination confirmed presence of at least one alive worm in the affected kidney. A unilateral nephrectomy was performed; one female (60 × 5 cm) and one male (30 × 3.8 cm) live worm were taken out of the extremely thin walled right kidney. One month later, due to failure of the remained kidney and poor condition, the patient deceased. We conclude that dioctophymosis can be found in cold and or relatively dry area. Moreover, the results showed that the worm was not affected with common anthelmintic drugs. PMID:27095981

Percutaneous nephrostomy (PCN) catheters are placed under combined ultrasound and fluoroscopic guidance in the interventional radiology suite and present unique challenges in neonates and infants. The purpose of this study was to demonstrate feasibility of PCN using a "14-4" (trocar and cannula) technique on neonates and infants. Between September 2009 and June 2014, data for 27 kidneys from consecutive 22 neonates or infants who underwent PCN catheter placement using the "14-4" technique were retrospectively analyzed. The median age at the time of placement of the PCN catheters was 11 days (range 5-300 days). There were 18 males and 4 females. All procedures were performed in the interventional radiology suite but without using fluoroscopy. Unilateral PCN was performed on 17 out of 22 patients, while bilateral drainage was performed on five patients. The technical success rate was 100%. The median duration of PCN catheter was 75 days (range 10-138 days). Minor macroscopic hematuria not requiring blood transfusion was present in two of the patients in which the hematuria lasted in 2 days. Placement of PCN catheters using a "14-4" technique with ultrasound as the sole imaging modality is a technically feasible and desirable option for neonates or infants. The technique obviates the need for ionizing radiation and potentially could be performed in the ultrasound room or even at the bedside.

Urethral polyp is one of differential diagnoses for the male patients complain of gross-hematuria and/or hematospermia. However, there have been limited numbers of case reports including infectious etiology. Here we reported clinical course and pathological findings of one rare case who was diagnosed and treated as urethral polyp-like lesions on the prostatic urethra caused by Chlamydia trachomatis infection. A 25 year-old man who had a past history of frequent sexual intercourse with unspecified female sexual partner visited the clinic. His chief complaint was gross-hematuria and hematospermia. Endoscopic findings showed that non-specific hemorrhagic polyp-like lesions. To determine the pathological findings including malignant diseases and diagnosis, transurethral resection was performed. Because the pathological findings were similar to those of chlamydial proctitis, additional examination was done. As the results, nucleic acid amplification test of C. trachomatis in urine specimen was positive and immunohistochemical staining of specific chlamydia antigen in resected specimen was also positive. Treatment by orally minocyline 100 mg twice daily for 4 weeks was introduced. After the treatment, symptom was disappeared and nucleic acid amplification test of C. trachomatis in urine specimen turned to be negative. No recurrence was reported 2 years posttreatment.

Hemorrhagic cystitis is a common complication in hematopoietic stem cell transplant recipients. We report here a case of severe BKV-associated hemorrhagic cystitis who did not respond to intravenous cidofovir. Overt hematuria successfully resolved after a few days on hyperbaric oxygen and intravesical instillations of cidofovir, while BK viruria dropped after a few weeks and remained low. We review the literature for therapeutic options in hemorrhagic cystitis and try to explain how hyperbaric oxygen stimulates mucosal repair in the urinary bladder.

This communication presents three cases of prolonged macroscopic hematuria in young subjects. Complementary explorations eliminated urologic or vascular causes. Renal biopsies showed minimal glomerular lesions with light microscopy, normal basement membranes in electron microscopy and mesangial deposits of C3 and properdine in immunofluorescence. Although the mesangial deposits of C3 lack specificity and the number of observations is small, it appears useful to report such cases so as to indicate their frequency and perhaps their autonomy, in glomerular hematuric nephropathies.

A 5-month-old intact female domestic shorthaired cat had mydriasis, agitation, and increased locomotion after ingestion of lisdexamfetamine, 10.3 mg/kg body weight (BW). Despite treatment with IV fluids, IV acepromazine, oral cyproheptadine and intravenous lipid emulsion the patient's clinical signs worsened. Dexmedetomidine administered at 2 μg/kg BW and continued at 0.5 μg/kg BW per hour rapidly controlled the patient's signs. An episode of vomiting and hematuria developed. Follow-up 5 days after discharge revealed that the cat appeared normal.

Nontraumatic Exertional Rhabdomyolysis Leading to Acute Kidney Injury in a Sickle Trait Positive Individual on Renal Biopsy.

2018-01-01

A 26-year-old African American male with a history of congenital cerebral palsy, sickle cell trait, and intellectual disability presented with abdominal pain that started four hours prior to the hospital visit. The patient denied fever, chills, diarrhea, or any localized trauma. The patient was at a party at his community center last evening and danced for 2 hours, physically exerting himself more than usual. Labs revealed blood urea nitrogen (BUN) level of 41 mg/dL and creatinine (Cr) of 2.8 mg/dL which later increased to 4.2 mg/dL while still in the emergency room. Urinalysis revealed hematuria with RBC > 50 on high power field. Imaging of the abdomen revealed no acute findings for abdominal pain. With fractional excretion of sodium (FeNa) > 3%, findings suggested nonoliguric acute tubular necrosis. Over the next couple of days, symptoms of dyspepsia resolved; however, BUN/Cr continued to rise to a maximum of 122/14 mg/dL. With these findings, along with stable electrolytes, urine output matching the intake, and prior use of proton pump inhibitors, medical decision was altered for the possibility of acute interstitial nephritis. Steroids were subsequently started and biopsy was taken. Biopsy revealed heavy deposits of myoglobin. Creatinine phosphokinase (CPK) levels drawn ten days later after the admission were found to be elevated at 334 U/dl, presuming the levels would have been much higher during admission. This favored a diagnosis of acute kidney injury (AKI) secondary to exertional rhabdomyolysis. We here describe a case of nontraumatic exertional rhabdomyolysis in a sickle cell trait (SCT) individual that was missed due to findings of microscopic hematuria masking underlying myoglobinuria and fractional excretion of sodium > 3%. As opposed to other causes of ATN, rhabdomyolysis often causes FeNa < 1%. The elevated fractional excretion of sodium in this patient was possibly due to the underlying inability of SCT positive individuals to reabsorb

Rationale: Almost half of the patients with anti-neutrophil cytoplasmic antibodies (ANCA) associated small vessel vasculitis relapse and their characteristics are still to be defined Objective: We aimed to evaluate the relapse rate and its determinants in a cohort of patients with ANCA associated vasculitis with severe kidney involvement. Methods and results: This is a retrospective study which included 100 patients consecutively admitted in a Nephrology Department with crescentic pauci-immune glomerulonephritis diagnosed by kidney biopsy. ANCAs were assessed by capture ELISA or indirect immunofluorescence (IFI). Patients were followed for a median period of 3.2 [0.1; 5.5] years. The median age was 61.6 years. The clinical condition at presentation was severe (median BVAS 16 and BVAS over 21 in one quarter of patients), mostly because of general, kidney and lung scores. Median creatinine was 5.7 mg/dL and 17% of the patients needed temporary dialysis. Eight patients relapsed (13.8%): one in the lung and seven in the kidney. The median time to relapse was 11.3 [9.2; 19.9] months. None of the investigated parameters allowed for differentiating patients who relapsed from those who did not, except higher hematuria in those who relapsed. Discussion: In our patients with ANCA vasculitis and severe kidney involvement, the relapse rate is low and hematuria but not ANCA specificity or clinical presentation allows the prediction of relapse.

Little is known about the frequency and significance of clinically unapparent or occult hemorrhage in ITP. Therefore, we prospectively explored the sites and frequency of occult bleeding in children with severe ITP at diagnosis or upon symptomatic relapse in a prospective, single-institution cohort study of patients ≤ 18 years of age and a platelet count ≤ 10,000/mm(3) . Data collected included bleeding severity assessment, urinalysis, fecal occult blood testing, and non-contrast brain MRI. Stool and urine samples were tested within 7 days of diagnosis or symptomatic relapse. Three months after diagnosis or relapse a noncontrast brain MRI evaluated hemosiderin deposits resulting from prior localized hemorrhage. Fifty-two ITP patients were enrolled with a mean platelet count of 4,000/mm(3) . A significant occurrence of occult hemorrhage was identified in the urine (27%) compared with clinically overt hematuria (0.91%, P < 0.0005). CNS microbleeding in the superficial cortex of the left frontal lobe was identified in one child with occult bleeding in the urinary tract. There was no relationship between occult hemorrhage and bleeding manifestations on physical examination. Occult hemorrhage was not a harbinger of subsequent bleeding. Our findings suggest that occult hemorrhage occurs with greater frequency than overt bleeding in children with severe ITP. CNS microbleeding is a potential risk in this patient population. Assessment of brain microbleeds and microscopic hematuria in this patient population require additional study. © 2015 Wiley Periodicals, Inc.

Urine protein/creatinine ratio as a mortality risk predictor in non-diabetics with normal renal function.

2012-01-01

Determine the relative mortality in apparently healthy adults with various levels of urinary protein measured by urine protein/creatinine (p/c) ratio. By use of the Social Security Death Master File, mortality in 2010 was determined for 7.5 million life insurance applicants age 20 to 89 providing urine samples between 1992 and 2006. Relative mortality by Cox regression for bands of p/c ratios was determined using age and sex as covariates and with an age split at 60 after excluding those with hematuria (> 3 red cells/hpf), diabetes, evidence of blood sugar elevation, or eGFR < 60 mL/min. After the exclusions noted above, relative mortality increased to 160% beginning at a p/c ratio of 0.11 mg/mg and rose steadily above that value regardless of sex and age. Most of this risk was not explained by a history of hypertension or elevated systolic blood pressure. Albumin testing identified roughly a third of urine samples with elevated p/c ratios as not containing albumin; those cases appeared to be associated with much lower risk as long as the p/c ratio was < or = 1.0 mg/mg. Low levels of proteinuria identified as urine protein/creatinine ratios of 0.11 mg/mg or higher (much lower than the usual lower cut-off value of 0.21) are associated with substantial excess mortality risk, even after excluding diabetics and those with reduced kidney function or hematuria.

To investigate chronic kidney disease (CKD) and its risk factors in people receiving physical examination. This retrospective study included people over 20 years old who had physical examination in the Health Management Center of Third Xiangya Hospital from Janurary 2008 to June 2011. CKD and its risk factors as well as questionnaire were recorded. The risk factors were analyzed by multivariate logistic analysis. CKD was defined by kidney damage (microalbuminuria≥30 mg/L) and/or hematuria and/or reduced kidney function [evaluate glomerular filtration rate (eGFR)<60 mL/(min.1.73 m2)]. We counted eGFR according to the modification of diet in renal disease (MDRD). A total of 5 708 physical examination reports were included. The detection rate of albuminuria, reduced renal function and hematuria was 25.0%, 1.7% and 1.1%. The detection rate of CKD was 25.6%, and detection rate of CKD stage 1-5 was 17.8%, 6.7%, 1.1%, 0 and 0, respectively. Multivariate logistic analysis indicated that diabetes mellitus, hypertension, hypercholesterolemia, male, age, and smoking were the risk factors for CKD. Increasing physical activity was the protective factor against CKD. High prevalence of CKD in people receiving physical examination is found in Changsha, especially stage 1 and 2 CKD. Physical examination is important to screen CKD. Stopping smoking, control of blood glucose, blood pressure, blood lipids and increasing physical activity may help reduce the prevalence of CKD.

Schistosomiasis is a highly prevalent parasitic disease in Senegal. The early symptoms are hematuria and dysuria. Children's comprehension of the disease is fundamental to preventing the infection. The aim of this study was to investigate the knowledge attitudes, and practices related to schistosomiasis among schoolchildren in 2 rural villages in Northern Senegal and to evaluate their impact on the disease. A cross-sectional study was conducted. Data about children's knowledge of schistosomiasis, behavior, and preventive measures were collected through a questionnaire. Questionnaire responses from 575 schoolchildren were analyzed. Correct answers about risky behavior for schistosomiasis were associated with early symptoms (P = 0.010). Wearing shoes and washing hands with soap were associated with not having hematuria and dysuria (P = 0.007 and 0.049, respectively). Playing in rivers was associated with the aforementioned symptoms (P < 0.001). Children who had good knowledge of schistosomiasis reportedly did not have symptoms (P = 0.002). A logistic regression model showed that female sex (odds ratio = 0.35; P = 0.01) and attending a primary school (odds ratio = 0.13; P < 0.001) were significant predictors of a lower risk of the early symptoms of urinary schistosomiasis. This study revealed that the level of knowledge among children in North Senegal about the causes, transmission, prevention, and treatment of schistosomiasis warrants implementing educational intervention.

Continuous technical innovations are not enough to resolve the high incidence of fistula after hypospadias repair. A urethral catheter-tutor made of reabsorbable polymeric biomaterial (RPB) which could be left in situ long enough could reduce the complications. To investigate in an animal model differents RPB to be used in urology. CRL Wistar rats, males, divided into 5 equal groups according to the used polymers: polylactide; lactic-coprolactone copolymer; lactic-glycolic copolymer; simulated; control silicones. Three individuals were sacrificed per group at 4th, 10th and 16th week. In all animals (exceptuating the simulated group), biomaterial was fixed to the bladder wall bylaparotomy. Animals remained in individual housing and kept under daily control of hematuria during the first 15 days and weekly weight and urine control for pH and lactate. After being slaughtered, remaining polymer was collected for chemical analysis and bladder tissue for hystologic study. There was no mortality, hematuria nor other clinical signs. The bladder wall showed a mild foreign body reaction. The values of lactate and pH in urine did not reach toxic levels. Lactic-glycolic was totally reabsorbed by the 10th week and had the lowest degree of calcification. Polylactide and lactic-coprolactone remained intact. The model of urinary bladder has proven useful for studying the degradation of bioresorbable polymers. The analyzed polymers have spent long time to be reabsorbed, so we will have to study new others.

The use of intravesicular alteplase for thrombolysis in a dog with urinary bladder thrombi.

To describe the use of alteplase for intravesicular thrombolysis in a dog after development of urinary tract obstruction from a blood clot in the urinary bladder. A 5.8 kg, 6.5-year-old female neutered Bichon Frise was presented for signs of acute hematuria. A complete blood count (CBC) revealed marked thrombocytopenia and leukopenia, and nonregenerative anemia. Bone marrow aspirate cytology revealed mild hypercellularity, mild megakaryocytic hyperplasia, mildly left-shifted erythroid maturation, and moderately left-shifted myeloid maturation, suggesting ongoing recovery from an acute bone marrow insult. Thrombocytopenia and hematuria resolved concurrently; however, stranguria and oliguria developed acutely. Ultrasonography identified two large presumed thrombi within the urinary bladder. A urinary catheter was placed and 4 doses of 0.5 mg of alteplase diluted in 10 mL of 0.9% sodium chloride were instilled into the bladder with a 4-hour dwell time at 12-hour intervals. Prothombin and activated partial thromboplastin times were monitored during therapy and remained within normal limits. One thrombus was successfully dissolved after 48 hours of therapy and the remaining thrombus was reduced in size and was voided upon removal of the urinary catheter. This report describes the use of alteplase in a dog for thrombolysis of intravesicular thrombi. In patients that develop intravesicular thrombi, intravesical instillation of alteplase can be considered as a method for dissolution of these thrombi. © Veterinary Emergency and Critical Care Society 2017.

A 5-year-old 8.6-kg (18.9-lb) spayed female Pug was evaluated because of chronic hematuria and recurrent urinary tract infections. Excretory urography, ultrasonography, and excretory CT urography were performed. Results indicated that the dog had bilateral hydronephrosis and hydroureter and suspected proximal ureteral stenosis. Retrograde ureteropyelography confirmed the presence of stenosis at the ureteropelvic junction of each ureter, along with a large amount of endoluminal ureteral debris. Clinical findings suggested that the dog had a congenital bilateral anomaly of the upper urinary tract. The dog was anesthetized, and 2 double-pigtail ureteral stents were placed cystoscopically with fluoroscopic guidance for immediate relief of the ureteropelvic junction obstructions. Each stent extended from the left or right renal pelvis to the urinary bladder. The procedures and the patient's recovery from anesthesia were uncomplicated. Continuing improvements in severity of hydronephrosis, hydroureter, and dysuria were evident during routine follow-up examinations at 2, 4, 12, 16, and 45 weeks after stent placement. Over the subsequent 12 months, all clinical signs remained resolved other than a urinary tract infection that was successfully treated with antimicrobials. Ureteral stenosis should be considered as a differential diagnosis for hydronephrosis in dogs, particularly when urinary tract calculi or neoplasia is not present. Chronic hematuria and recurrent urinary tract infections can be associated with this condition. Placement of ureteral stents may be a successful treatment option for ameliorization of congenital ureteral obstructions.

We sought to provide a technical update on the use of a prostate morcellator device (PMD) to manage organized blood clots of the bladder following laser prostatectomy. Herein, we describe our experience in using the Wolf Piranha morcellator in managing organized bladder blood clots supplemented with a retrospective chart review of the patients in whom this procedure was performed. Six patients, all male with a mean age of 75 ± 8.9 years, had organized bladder clots following either holmium laser enucleation or photoselective vaporization of the prostate managed with a PMD. Clots were recognized based on hematuria or urinary retention a median of 3.5 days following the aforementioned procedures. Initial management was attempted with more conservative measures, including a three-way Foley catheter, followed by cystoscopy with an Ellik evacuator, or a glass Tommey syringe. Morcellation times were a mean of 10.2 ± 6.15 minutes (range 2-18). This technique was able to manage clots that were an average of 173.3 ± 115.9 cc in size. The procedure was well-tolerated. No patients experienced intraoperative or morcellator-related complications. Benign prostatic hypertrophy frequently requires surgical endoscopic management and can be complicated by hematuria and bladder blood clot formation. When these clots become organized, this can lead to urinary retention and the required management, evacuation, may be difficult. The use of a Wolf Piranha PMD is a safe, well-tolerated, and effective in evacuating organized blood clots of the bladder.

A 7 yr old castrated male standard poodle weighing 25 kg was presented with a 5 day history of hematuria, dysuria, and the presence of a 2.5 cm, firm swelling within the prepuce. Abdominal radiographs revealed a soft-tissue mass on the distal prepuce and lysis of the cranial margin of the os penis. The patient was sedated and an ulcerated hemorrhagic mass was identified at the tip of the penis. The mass was diagnosed as hemangiosarcoma via incisional biopsy. A penile amputation with scrotal urethrostomy was performed followed by chemotherapy with doxorubicin.

Cancers of the lower urinary tract can arise from the bladder, urachus or urethra. Urothelial carcinoma of the bladder (UCB) is the most common of these. The presentation of bladder, urachal and urethral cancers can differ but many result in hematuria as an initial indication. The diagnosis and staging of these cancers often necessitate radiologic imaging often in the form of cross-section CT urography or MR urography. The following article reviews the specific nature of lower tract cancers and their imaging. Copyright © 2017 Elsevier B.V. All rights reserved.

Henoch-Schonlein purpura is an immunoglobulin A (IgA)-immune complex mediated leukocytoclastic vasculitis that classically manifests with palpable purpura, abdominal pain, arthritis, and hematuria or proteinuria. The condition is much more predominant in children (90% of cases) and commonly follows an upper respiratory infection. We present a case of recurrent Henoch-Schonlein purpura (HSP) complicated by nephritis in an adult female initially categorized as IgA nephropathy (IgAN). We review the pathophysiologic basis of HSP nephritis as the variant of HSP accompanied by renal involvement and its pathogenetic commonality with IgA nephropathy.

A 47-year-old, previously healthy farmer from Grafton, N.S.W. in Australia, developed loin pain and hematuria 2 months after minor trauma to his loin. A renal cyst was found by ultrasound and arteriography. At operation, a thick-walled cyst containing 800 ml of clotted blood was excised together with a small wedge of kidney. Ring-like structures measuring 70 X 45 mu were found in the fibrous cyst wall and in the surrounding fat. These birefringent double-walled "rings" with equally spaced radial striations were identified as the eggs of Dioctophyma renale.

Small cell carcinoma of the urinary bladder is an uncommon tumor that has been described in case reports or small series. We report a new case in a 67-year-old male who presented with gross hematuria and irritative symptoms. Cystoscopy revealed an extensive mass of the bladder and computed tomography scan showed an important thickening of the bladder wall. Diagnosis of small cell carcinoma was established after radical cystectomy and microscopic examination. The patient received pelvic hemostatic radiotherapy and platinium-based chemotherapy. Three months after the diagnosis, he developed bone, renal and adrenal metastases.

Nutcracker phenomenon is the descriptor for a patient's anatomy whenever the left renal vein becomes compressed between the abdominal aorta and the superior mesenteric artery. Nutcracker syndrome is the terminology used when the nutcracker phenomenon is accompanied by symptoms including pain (abdominal, flank, pelvic), hematuria, and orthostatic proteinuria. Diagnosis can be made with Doppler ultrasound, venography, computed tomography, or magnetic resonance imaging. This case demonstrates some of the typical findings of nutcracker syndrome. The limited clinical features and interesting imaging findings, in addition to the young age of the patient, make this a notable case.

Cole disease is a genodermatosis of pigmentation following a strict dominant mode of inheritance. In this study, we investigated eight patients affected with an overlapping genodermatosis after recessive inheritance. The patients presented with hypo- and hyperpigmented macules over the body, resembling dyschromatosis universalis hereditaria in addition to punctuate palmoplantar keratosis. By homozygosity mapping and whole-exome sequencing, a biallelic p.Cys120Arg mutation in ectonucleotide pyrophosphatase/phosphodiesterase 1 (ENPP1) was identified in all patients. We found that this mutation, like those causing dominant Cole disease, impairs homodimerization of the ENPP1 enzyme that is mediated by its two somatomedin-B-like domains. Histological analysis revealed structural and molecular changes in affected skin that were likely to originate from defective melanocytes because keratinocytes do not express ENPP1. Consistently, RNA-sequencing analysis of patient-derived primary melanocytes revealed alterations in melanocyte development and in pigmentation signaling pathways. We therefore conclude that germline ENPP1 cysteine-specific mutations, primarily affecting the melanocyte lineage, cause a clinical spectrum of dyschromatosis, in which the p.Cys120Arg allele represents a recessive and more severe form of Cole disease.

We previously reported that three point mutations in SASH1 and mutated SASH1 promote melanocyte migration in dyschromatosis universalis hereditaria (DUH) and a novel p53/POMC/Gαs/SASH1 autoregulatory positive feedback loop is regulated by SASH1 mutations to induce pathological hyperpigmentation phenotype. However, the underlying mechanism of molecular regulation to cause this hyperpigmentation disorder still remains unclear. In this study, we aimed to investigate the molecular mechanism undergirding hyperpigmentation in the dyschromatosis disorder. Our results revealed that SASH1 binds with MAP2K2 and is induced by p53-POMC-MC1R signal cascade to enhance the phosphorylation level of ERK1/2 and CREB. Moreover, increase in phosphorylated ERK1/2 and CREB levels and melanogenesis-specific molecules is induced by mutated SASH1 alleles. Together, our results suggest that a novel SASH1/MAP2K2 crosstalk connects ERK1/2/CREB cascade with p53-POMC-MC1R cascade to cause hyperpigmentation phenotype of DUH. © 2017 The Authors.

Polyoma BK virus (BKV) is frequently identified in the urine of bone marrow transplantation (BMT) patients with hemorrhagic cystitis (HC). However, viruria is common even in asymptomatic patients, making a direct causative role of BKV difficult to establish. This study prospectively quantified BK viruria and viremia in 50 BMT patients to define the quantitative relationship of BKV reactivation with HC. Adenovirus (ADV) was similarly quantified as a control. More than 800 patient samples were quantified for BKV VP1 gene with a real-time quantitative polymerase chain reaction. Twenty patients (40%) developed HC, 6 with gross hematuria (HC grade 2 or higher) and 14 with microscopic hematuria (HC grade 1). When compared with asymptomatic patients, patients with HC had significantly higher peak BK viruria (6 x 10(12) versus 5.7 x 10(7) genome copies/d, P <.001) and larger total amounts of BKV excreted during BMT (4.9 x 10(13) versus 7.7 x 10(8) genome copies, P <.001). There was no detectable increase in BK viremia. Binary logistic regression analysis showed that BK viruria was the only risk factor, with HC not related to age, conditioning regimen, type of BMT, and graft-versus-host disease. Furthermore, the levels of ADV viruria in patients with or without HC were similar and comparable with those of BK viruria in patients without HC, suggesting that the significant increase in BK viruria in HC patients was not due to background viral reactivation or damage to the urothelium. BK viruria was quantitatively related to the occurrence of HC after BMT.

Hyperoxaluria is a metabolic disorder that can lead to end stage renal disease (ESRD). It can be either inherited or acquired. Primary hyperoxaluria (PHO) is more common and characterized by an excessive production of oxalate leading to recurrent urolithiasis and progressive nephrocalcinosis. Due to the high rate of consanguineous marriage in Jordan this disease is commonly diagnosed in pediatric nephrology clinics. We aimed to demonstrate the clinical pattern and progression to ESRD in pediatric patients with hyperoxaluria at Queen Rania Abdulla Children Hospital. Medical records of all patients followed up in the pediatric nephrology clinic with the diagnosis of PHO during the period between September 2007 and March 2013 were reviewed. There were 70 patients with the diagnosis of PHO, 52.9% were males. The median age at presentation was 3 years ± 3 months with the youngest child being two months old. Diagnosis was made in the first year of life in 15.7% of patients. The most common presenting symptom was hematuria, while 14% of patients were asymptomatic and detected by family screening after the diagnosis of an index case. At the time of initial presentation, 15.7% of patients had ESRD and 25% had impaired renal function. Kidney stones were found in 57% of cases and nephrocalcinosis was found in 37%. High index of suspicion is needed to diagnose PHO in children presenting with kidney stone or unexplained hematuria. Twenty-four hour urine collection for oxalate are required to make the proper diagnosis. Family screening, when appropriate, is indicated for early detection of PHO.

Development of immune-complex glomerulonephritis in athymic mice: T cells are not required for the genesis of glomerular injury.

Chronic injection of dextran into normal mice elicits a glomerulonephritis (GN) that models IgA nephropathy (IgAN) in humans. Since athymic mice lack T cells but nonetheless develop antibodies to polysaccharide antigens such as dextran (DEX), we used athymic mice to study the role of T lymphocytes in the induction of this form of GN, independent of the role of T cells in antibody synthesis. Both mice given injections of diethylaminoethyl (DEAE)-DEX and uninjected mice had circulating IgM and IgA anti-DEX antibodies, which apparently arise as 'natural antibodies', but immune complex GN was observed only in the injected mice. All of 15 injected mice exhibited capillary staining for IgA and IgM; none of 12 control mice contained such IgA deposits and only one had capillary staining for IgM (both P<0.001). In addition, IgG and C3 were detected in injected but not control animals. By light microscopy, injected mice exhibited marked expansion of mesangial matrix relative to controls. Electron microscopy showed no glomerular abnormalities in control mice, whereas injected mice showed large organized fibrillar deposits principally in the mesangium. Hematuria and proteinuria were present in all 15 injected mice, but only one of 11 control mice showed hematuria or proteinuria (both P<0.001). These results indicate that chronic injection of DEAE-DEX into athymic mice generates the same clinical and histologic features of GN as in euthymic mice, suggesting that T cells are not necessary to promote GN in this model.

Latent association between low urine pH and low body weight in an apparently healthy population.

Low urine pH, a plausible predictor for chronic kidney disease and metabolic disorders, is often observed in obese individuals. However, the association between low urine pH and low body weight is equivocal. We examined clinical parameters including urine pH and body mass index (BMI) in a cross-sectional study of 3629 apparently healthy Japanese adults aged 25-80 years who underwent a health-screening check-up. Urine pH was lower and the prevalence of proteinuria was significantly higher in subjects with BMI of ≥ 27.0 kg/m(2) compared with those with BMI of 21.0-22.9 kg/m(2). By contrast, hematuria was more prevalent in subjects with BMI of ≤ 20.9 kg/m(2). Logistic regression analysis showed that BMI of ≥ 27.0 kg/m(2) was significantly associated with low urine pH (≤ 5.5), which remained significant after adjustment for relevant confounders including age, sex, proteinuria, estimated glomerular filtration rate, urine density, hematuria, smoking status, and daily alcohol drinking. However, the association disappeared after further adjustment for serum uric acid. In contrast, the association between low urine pH and BMI of ≤ 19.0 kg/m(2) was significant after adjustment for age and sex and rather strengthened by the further adjustment for serum uric acid. In conclusion, low urine pH may be independently associated with low BMI. However, the underlying mechanisms of low urine pH in low body weight may differ from those in high body weight.

PurposeTo demonstrate the technical benefit of the double coaxial microcatheter technique for embolization of renal arteriovenous malformations (AVMs) with n-butyl cyanoacrylate and iodized oil (glue).Materials and MethodsSix consecutive patients (1 man and 5 women; mean age 61 years; range 44–77 years) with renal AVMs were included. Five patients had hematuria, and one had a risk of heart failure due to a large intrarenal arteriovenous shunt. All patients underwent transarterial embolization using glue and the double coaxial microcatheter technique with outer 2.6F and inner 1.9F microcatheters. After glue injection, the inner microcatheter was retracted, while the outer microcatheter was retained. We assessed themore » complications and clinical outcomes of this technique.ResultsTechnical success was achieved in all patients. In 9 sessions, 34 feeding arteries were embolized with glue using the double coaxial microcatheter technique, 1 was embolized with glue using a single microcatheter, and 2 were embolized with coils. The double coaxial microcatheter technique was useful for selecting small tortuous feeding arteries, preventing glue reflux to the proximal arteries, and approaching multiple feeding arteries without complete retraction of the microcatheters. As a minor complication, glue migrated into the venous system in four patients without any sequelae. In all patients, favorable clinical outcomes, including hematuria cessation in five patients and improvement of the large intrarenal arteriovenous shunt in one patient, were obtained without deterioration of renal function.ConclusionGlue embolization with the double coaxial microcatheter technique was useful for treating renal AVMs with multiple tortuous feeding arteries.« less

To study the methods for rapid establishment of rat models of IgA nephropathy. Forty female SD rats weighing 160-200 g were randomized into 3 groups. In group A, the rats received intravenous injection of staphylococcal enterotoxin B (SEB) and oral bovine serum albumin (BSA), and in group B, CCl4 was injected subcutaneously in addition to the above treatments; the rats in group C received no treatments to serve as the normal control group. The rats were sacrificed 10 and 14 weeks after the treatment for biochemical testing of the arterial blood and histopathological and IgA immunofluorescence examination of the renal tissues. The twenty-four-hour urine was collected at 10, 12, and 14 weeks after the treatments for detecting the urine proteins. Compared with the control group, the rats in groups A and B showed significantly increased serum creatinine, urine nitrogen and protein levels. Pathological examination of the renal tissue showed mild to moderate mesangial expansion and mesangial cell proliferation in groups A and B, without obvious difference between the two groups; but hematuria and proteinuria occurred earlier in group B with stronger IgA immunofluorescence than in group A. Both of the methods used in group A and group B can successfully induce IgA nephropathy in rats, but in group B, hematuria and urineprotein occurs earlier and IgA immunofluorescence is more stronger. Therefore intravenous SEB injection combined with oral BSA and subcutaneous CCl4 administration is a better method for time-efficient establishment of rat models of IgA nephropathy.

Asymptomatic renal calculi without any history of colic, hematuria or infection can be found as an incidental finding during preven-tive check-ups. The aim of our study was to eval-uate whether these stones provoke symptoms with the need for further treatment during the follow-up and whether they cause cortical defects which may consecutively affect the renal func-tion. In a prospective study we evaluated 104  patients with renal calculi. The -medical history, radiological findings and functional imaging as well as urine and blood analyses were recorded and evaluated. The influence of stone size and localisation on the development of acute stone-related symptoms, renal function and renal scarring were evaluated. Furthermore, we analysed whether localised pathological findings in radiographic or functional imaging may influence the creatinine level. The follow-up was be-tween 12 and 48  months (median: 25  months). During the study period 27 / 104 of our patients (26 %) developed symptomatic events (renal colic, hematuria, infection) in which patients with middle pole calculi with a mean -cumulative stone diameter of 9.8  mm had the -highest risk. A localised renal scarring could be found in 36.6 %. These patients had a significantly higher risk in presenting an increased creatinine level. Increasing stone size was diagnosed in 39  cases (37.5 %). Asymptomatic renal stones have to be controlled regularly in order to prevent the -patient from loss of renal function and hypertension caused by increasing stones or urinary tract infection. © Georg Thieme Verlag KG Stuttgart ˙ New York.

We reviewed the data of patients with upper urinary tract (UUT) tumors to evaluate the effectiveness of diagnostic procedures. This retrospective study evaluated tumor characteristics, imaging procedures, epidemiological and follow-up data of 113 patients. We analyzed the importance of non-invasive and endoscopic diagnosis in addition to imaging as well as the influence of stage and grade on recurrence rate. Most tumors were urothelial carcinomas (92.9%). The cardinal symptoms were hematuria (40.7%), flank pain (2.7%), and urinary obstruction (14.2%). Forty-seven patients received intravenous urograms (IVUs), 57 retrograde ureteropyelography (RUP), 89 CTs, 6 an MRI. The correct positive tumor identification was reached by IVU in 27/47 patients, by RUP in 50/57, by CT in 74/89, and by MRI in 3/6 patients representing sensitivities of 57.4% (IVU), 87.7% (RUP), 83.1% (CT), and 50% (MRI). Sixty-four patients had urine cytology, which was correctly positive in 60.9% and 56 had a diagnostic ureterorenoscopy, which was correctly positive in 83.9%. During follow-up more than 20% of patients developed a recurrence. In patients with hematuria and flank pain, UUT must be considered a differential diagnosis. UUT to the extent of 76.6% showed more invasive growth (>Ta). Thus, rapid and efficient diagnosis based primarily on imaging is required. Contrast CT scan seems to be the imaging modality with the best performance. However, often only a combination of diagnostic procedures gives a certain diagnosis. Due to the high recurrence rate, close follow-up is needed. © 2017 S. Karger AG, Basel.

To assess the impact of oral anticoagulation (OA) on morbidity of transurethral resection of the prostate (TURP). OA included warfarin and platelet aggregation inhibitors (PAI). Multicenter analysis of patients operated for symptomatic benign prostatic hyperplasia (BPH) by TURP. Patients under OA were compared to those with no OA. Out of 612 patients included in the analysis, 206 (33%) were on OA prior surgery (55 warfarin, 142 PAI, and 9 warfarin and PAI). No patient continued warfarin and clopidogrel during the operating period. Patients under OA were significantly older (75 vs. 71 yo, P < 0.001), had larger prostate volume (56 vs. 49 ml, P = 0.05), and had higher rate of bladder catheter prior surgery (26 vs. 17%, P = 0.02). At 3 months follow-up, patients in the OA group had a higher weight of resected tissue (24 vs. 21.7 g, P < 0.001), a longer duration of hospitalization (6.4 vs. 4.7 days P < 0.001), a higher rate of bladder clots (13 vs. 4.7%, P < 0.001), red cell transfusion (1.9 vs. 1.0%, P = 0.026), late hematuria (15.0 vs. 8.4%, P = 0.004), and thromboembolic events (2.4 vs. 0.7, P = 0.02). In multivariable analysis, OA status was the sole independent parameter associated with bladder clots (P = 0.004) and with late hematuria (P = 0.03). OA had a significant and independent impact on TURP outcome in terms of bleeding complications. This data could be used for treatment decision and for patient's information prior BPH surgery.

Bladder cancer in patients with spinal cord injury.

The incidence of bladder cancer in spinal cord injury (SCI) is 16 to 28 times higher than that in the general population. The objective of this study was to investigate the characteristics of bladder cancer that are unique to the SCI population. Retrospective review. The charts of 16 patients diagnosed with bladder cancer from 1982 to 2001 were reviewed for type of cancer, exposure to risk factors, presenting symptoms, and survival time. The presenting manifestations were gross hematuria in 14 patients, papillary urethral growth in 1 patient, and acute obstructive renal failure in 1 patient. The diagnosis was made on initial cystoscopic evaluation in 16 patients; 3 patients required further evaluation. Eight of the 11 screening cytologies were suspicious for a malignancy prior to the diagnosis. Seven patients had transitional cell carcinoma, 6 patients had squamous cell carcinoma (SCCA), and 3 patients had both. The bladder wasmanaged with chronic indwelling catheter in 12 patients. Nine patients died of bladder cancer metastases and the remaining 3 patients died of other causes. Six patients survived 5 years or more; 4 were still alive at the completion of this study. Gross hematuria in individuals with SCI warrants aggressive assessment for bladder cancer. Chronic indwelling catheter, smoking, and renal and bladder stones are important risk factors for cancer. The incidence of SCCA in the SCI popullation is much higher than in the general population. Cystoscopic and cytologic evaluation in patients with advanced disease may fail to confirm the diagnosis in a high proportion of patients.

Bladder pain syndrome/interstitial cystitis as a functional somatic syndrome.

PubMed

Warren, John W

2014-12-01

To determine whether bladder pain syndrome/interstitial cystitis (BPS/IC) has the characteristics of a functional somatic syndrome (FSS). There is no accepted definition of an FSS. Consequently, this paper reviewed the literature for common FSS characteristics and for reports that BPS/IC has these characteristics. Eleven articles met inclusion and exclusion criteria and yielded 18 FSS characteristics. BPS/IC patients manifest all but two: the exceptions were normal light microscopic anatomy (after hydrodistention under anesthesia, some BPS/IC bladders have Hunner's lesions and most have petechial hemorrhages) and normal laboratory tests (many BPS/IC patients have hematuria). Petechial hemorrhages and hematuria are probably related and may appear during naturally-occurring bladder distention. Without such distention, then, the 90% of BPS/IC patients without a Hunner's lesion have all the characteristics of an FSS. Comparisons in the opposite direction were consistent: several additional features of BPS/IC were found in FSSs. This systematic but untested method is consistent with but does not test the hypothesis that BPS/IC in some patients might best be understood as an FSS. Like most conditions, BPS/IC is probably heterogeneous; hence only a proportion of BPS/IC cases are likely to be manifestations of an FSS. This hypothesis has several implications. Explorations of processes that connect the FSSs might contribute to understanding the pathogenesis of BPS/IC. Patients with FSSs are at risk for BPS/IC and may benefit from future preventive strategies. Therapies that are useful in FSSs also may be useful in some cases of BPS/IC.

To determine test characteristics of CT urography for detecting bladder cancer in patients with hematuria and those undergoing surveillance, and to analyze reasons for false-positive and false-negative results. A HIPAA-compliant, IRB-approved retrospective review of reports from 1623 CT urograms between 10/2010 and 12/31/2013 was performed. 710 examinations for hematuria or bladder cancer history were compared to cystoscopy performed within 6 months. Reference standard was surgical pathology or 1-year minimum clinical follow-up. False-positive and false-negative examinations were reviewed to determine reasons for errors. Ninety-five bladder cancers were detected. CT urography accuracy: was 91.5% (650/710), sensitivity 86.3% (82/95), specificity 92.4% (568/615), positive predictive value 63.6% (82/129), and negative predictive value was 97.8% (568/581). Of 43 false positives, the majority of interpretation errors were due to benign prostatic hyperplasia (n = 12), trabeculated bladder (n = 9), and treatment changes (n = 8). Other causes include blood clots, mistaken normal anatomy, infectious/inflammatory changes, or had no cystoscopic correlate. Of 13 false negatives, 11 were due to technique, one to a large urinary residual, one to artifact. There were no errors in perception. CT urography is an accurate test for diagnosing bladder cancer; however, in protocols relying predominantly on excretory phase images, overall sensitivity remains insufficient to obviate cystoscopy. Awareness of bladder cancer mimics may reduce false-positive results. Improvements in CTU technique may reduce false-negative results.

Hyperbaric oxygen: Primary treatment of radiation-induced hemorrhagic cystitis

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

Weiss, J.P.; Neville, E.C.

Of 8 patients with symptoms of advanced cystitis due to pelvic radiation treated with hyperbaric oxygen 7 are persistently improved during followup. All 6 patients treated for gross hematuria requiring hospitalization have been free of symptoms for an average of 24 months (range 6 to 43 months). One patient treated for stress incontinence currently is dry despite little change in bladder capacity, implying salutary effect from hyperbaric oxygen on the sphincter mechanism. One patient with radiation-induced prostatitis failed to respond. This experience suggests that hyperbaric oxygen should be considered the primary treatment for patients with symptomatic radiation-induced hemorrhagic cystitis.

Carcinosarcoma of the urinary bladder is a uncommon tumor with characteristic histopathologic and immunohistochemical findings; his histogenesis have still not been clear; the prognosis seems to be improved by radical cystectomy and adjuvants therapies. We report a case of 47 years old women suffering from suprapubic pains, dysuria and hematuria of five months duration and had a 10 cm suprapubic mass that was found on physical examination. Radiographically, the tumor invaded the dome of the urinary bladder and causes bilateral hydronephrosis. Microscopically it was an urinary bladder carcinosarcoma. Our objective is to discuss the histogenesis, the anatomoclinical and prognosis of these rare tumors.

Glanzman thrombasthenia is a rare hematologic disorder characterized by qualitative thrombocyte abnormality. Patients present with episodic mucocutaneous bleeding. Thrombosis is a paradox phenomenon observed in patients with Glanzman thrombasthenia and generally considered as a treatment complication. We present a 16-year-old girl referred for severe flank pain beginning after treatment of hematuria due to Glanzman thrombasthenia. The patient underwent endoscopy for further diagnosis and treatment because of the failure of radiologic evaluation. Although the resolution of the large clots was obtained with streptokinase instillation via the ureteral catheter, clot was mobilized with gentle insertion of ureteral catheter in the present case.

Perforation of the bladder related to long-term indwelling urethral catheter is a rare and serious complication. A 85-year-old man with an indwelling urethral catheter presented severe hematuria, abdominal pain with rebound tenderness and muscular tension over the suprapubic area after the exchange of the urethral catheter. Computed tomography and cystogram revealed experitoneal bladder perforation due to indwelling catheter. Three weeks after the indwelling urethral catheter had been placed, the perforation was closed. In most cases, laparotomy and suprapubic cystostomy are performed. We describe the case of experitoneal bladder perforation successfully treated by urethral drainage.

Primary bladder tumor is a frequent urological malignancy, whereas the incidence of secondary bladder tumor from a distant organ is quite rare. Secondary bladder neoplasms represent 1% of all malignant bladder tumors, of which distant metastases from stomach account for about 4% of cases. We present the case of a 30-year-old male who underwent partial gastrectomy for Signet-ring cell carcinoma of the stomach and presented 2 years later with hematuria. On computerized tomography scan, a bladder tumor was found which was resected cystoscopically. The histopathological examination revealed secondary Signet-ring cell adenocarcinoma of the urinary bladder.

The spongy body of the penis metastasis from other primary sites is a rare clinical entity. It is frequently associated with widespread metastatic disease and poor prognosis clinically. We report a case of a 61-year-old man with a previous history of cystectomy due to infiltrating urothelial carcinoma of the bladder 12 months ago and presented with penile shaft swelling pain and hematuria for 3 months. The restaging F-FDG PET/CT scan demonstrated a hypermetabolic mass at his penile shaft. This lesion was confirmed on phallectomy to be infiltrating urothelial carcinoma metastasis from the known primary bladder tumor.

Coagulopathy induced by saw palmetto: a case report.

Saw palmetto is the most popular herbal supplement used to treat symptoms of benign prostatic hyperplasia (BPH). The safety and efficacy of saw palmetto has been established in the literature. While the majority of studies document the efficacy and safety of saw palmetto, some studies document the adverse side effects, including increased risk of bleeding. There are no reports in the literature about increased prothombin time (PT), partial thromboplastin time (PTT) or international normalized ratio (INR) while using saw palmetto. We present a case of hematuria and coagulopathy in a patient who was using saw palmetto.

Symptoms secondary to a vaginal foreign body are responsible for approximately 4% of pediatric gynecologic outpatient visits.(1) The classic symptom is vaginal bleeding, but vaginal discharge, foul odor, irritation, abdominal pain, and hematuria have been described. We are reporting a case of a microscopic vaginal foreign body presenting as hematochezia in a preadolescent girl. This case is unique in that the patient presented with bleeding with defecation, without vaginal bleeding. Vaginal foreign bodies can present with diverse symptomatology. Physicians should consider the diagnosis of vaginal foreign body when presented with a young female patient with unexplained hematochezia.

Small cell carcinoma of the urinary bladder is an uncommon tumor that has been described in case reports or small series. We report a new case in a 67-year-old male who presented with gross hematuria and irritative symptoms. Cystoscopy revealed an extensive mass of the bladder and computed tomography scan showed an important thickening of the bladder wall. Diagnosis of small cell carcinoma was established after radical cystectomy and microscopic examination. The patient received pelvic hemostatic radiotherapy and platinium-based chemotherapy. Three months after the diagnosis, he developed bone, renal and adrenal metastases. PMID:29147197

Foley catheter failure is uncommon and Foley catheter failure associated with iatrogenic urinary bladder rupture (IUBR) is extremely rare. Symptoms are often nonspecific and thus misdiagnosis and delayed treatment is common. In this case report, we present a case of IUBR in a woman from Foley catheter failure, which ultimately led to her demise. This case adds to the literature the importance of suspicion for IUBR in patients with indwelling Foley catheters presenting with lower abdominal pain, hematuria, and decreased urine output.

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.

To identify the underlying cause of clinical signs in cats with nonobstructive diseases of the bladder and urethra. Prospective case series. 109 cats examined by the urology service of The Ohio State University's veterinary teaching hospital because of stranguria, hematuria, pollakiuria, or urination in inappropriate locations. History was obtained and a CBC, serum biochemical analyses, serologic tests for FeLV and feline immunodeficiency virus, urinalysis, bacterial culture of urine, and contrast radiography or urethrocystoscopy (females only) were performed. 16 cats had cystic calculi: 8 had struvite uroliths, 7 had calcium oxalate uroliths, and 1 had a urolith of unknown composition in conjunction with an anatomic defect. Anatomic defects, including diverticulae, urethral strictures, and a malpositioned urethra, were identified in 12 cats. A urinary tract infection was identified in 1 cat, and neoplasia was diagnosed in 2. One of the cats with neoplasia also had a struvite urolith. The remaining 80 cats did not have an anatomic defect, urolith, or tumor. Ten of these cats also did not have radiographic or cystoscopic abnormalities and were presumed to have a behavioral disorder. The remaining 70 cats had radiographic or cystoscopic abnormalities, and idiopathic cystitis was diagnosed. In 14 of the cats with idiopathic cystitis, results of a urinalysis were normal. Cats with idiopathic cystitis were significantly more likely to eat dry food exclusively (59%) than were cats in the general population (19%). Results suggest that idiopathic cystitis occurs commonly in cats with stranguria, hematuria, pollakiuria, or inappropriate elimination and is associated with consumption of dry foods. Contrast radiography or cystoscopy is necessary for differentiating idiopathic cystitis from behavioral disorders in some cats.

Penile fracture and its treatment: is retrograde urethrograghy necessary for management of penile fracture?

Penile fracture, being defined as rupture of the tunica albuginea of the corpus cavernosum, is uncommon. Here, we analyze findings on our patients during a 10-year period and evaluate the role of retrograde urethrography. From February 2002 to April 2012, 116 patients were admitted with penile fracture at Ghaem Medical Center. Patient history and physical examination were taken at their admittance to detect probable urethral injury. Before surgery, retrograde urethrography was performed in all patients. The size and site of the tunical rupture were recorded. Then the rupture of tunica albuginea was sutured with nonabsorbable (3-0 nylon) sutures and the ties were placed on the internal surface (continuous method). All patients were followed up for 12 months. Patients' mean age was (32.78 ± 10.61) years and ranged (16-62) years. The mechanism of trauma was sexual intercourse in 103 patients (89%) and masturbation in 13 patients (11%). The most common site of injury found after exploration was right (55%) and lateral (74%) of the corpus cavernosum. The size of the tunical rupture was from 0.5 to 3.0 cm (mean 1.88 ± 0.72). Three of the patients had Marphan's syndrome. Urethral injury was detected by retrograde urethrography in 4 patients (3%) who had macroscopic hematuria and urethrorrhagia. During 12 months follow-up, no complication was seen. There is no need to perform retrograde urethrography unless the patients have gross hematuria or urethrorrhagia. The key to success in treatment of penile fracture is to achieve a rapid diagnosis based on history and a physical examination, avoid unnecessary imaging tests and perform immediate surgery to reconstruct the site of injury.

Mutations in the COL4A3/COL4A4 genes of type IV collagen account for about 40% of cases of thin basement membrane nephropathy, a condition that is estimated to affect 1% or more of the general population. We recently described 10 Cypriot families with familial hematuria and thin basement membrane nephropathy in the presence of focal segmental glomerulosclerosis, with founder mutations on COL4A3 gene. Seven of the families carried mutation G1334E on haplotype K, and another three carried mutation G871C on haplotype Ky. In this report we performed extension of the haplotypes with additional polymorphic markers, 12 for haplotype K and 22 for haplotype Ky, to estimate the linkage disequilibrium value between the mutation and flanking noncommon markers. Haplotype Ky extended to 13.71 Mb, but we did not attempt further analysis owing to the small number of chromosomes. Haplotype K extended to 3.83 Mb, thereby suggesting that it was a much older event compared to mutation G871C. Mutation G1334E was calculated to be about 5-10 generations old with a possible origin between 1693 and 1818 AD, during the Ottoman ruling of the island. Both mutations are clustered in specific geographic regions with apparently formerly isolated populations, although mutation G1334E has been detected elsewhere on the island. The identification of founder mutations in large families with microscopic hematuria greatly facilitates presymptomatic diagnosis and provides useful information on the history of the population, while it may also assist in association studies in search for disease modifier genes.

Alport syndrome (ATS) is a progressive hereditary nephropathy characterized by hematuria and proteinuria. It can be associated with extrarenal manifestations. In contrast, thin basement membrane nephropathy (TBMN) is characterized by microscopic hematuria, is largely asymptomatic, and is rarely associated with proteinuria and end-stage renal disease. Mutations have been identified in the COL4A5 gene in ATS and in the COL4A3 and COL4A4 genes in ATS and TBMN. To date, more than 1000 different mutations in COL4A5, COL4A3, and COL4A4 are known. In this study mutational analysis by exon sequencing and multiplex ligation-dependent probe amplification was performed in a large European cohort of families with ATS and TBMN. Molecular diagnostic testing of 216 individuals led to the detection of 47 novel mutations, thereby expanding the spectrum of known mutations causing ATS and TBMN by up to 10 and 6%, respectively, depending on the database. Remarkably, a high number of ATS patients with only single mutations in COL4A3 and COL4A4 were identified. Additionally, three ATS patients presented with synonymous sequence variants that possible affect correct mRNA splicing, as suggested by in silico analysis. The results of this study clearly broaden the genotypic spectrum of known mutations for ATS and TBMN, which will in turn now facilitate future studies into genotype-phenotype correlations. Further studies should also examine the significance of single heterozygous mutations in COL4A3 and COL4A4 and of synonymous sequence variants associated with ATS.

ANCA vasculitis in a patient with Alport syndrome: a difficult diagnosis but a treatable disease!

Alport syndrome and ANCA-associated vasculitis are both rare diseases. The co-existence of these two conditions has never been reported. There is no obvious pathogenic link between these two glomerular diseases. The management of this case highlights the importance of a systematic approach when investigating the unexpected unfavourable evolution of a known glomerulopathy. A-17 year old caucasian boy with a genetically proven X-linked Alport syndrome presented with progressive dyspnea, fatigue and pallor. His blood tests showed a severe anemia (Hb 6.9 g/dl) with acute worsening of kidney function (serum creatinine, normal 9 months earlier, was now 3.6 mg/dl). Microscopic hematuria and proteinuria also worsened. He soon developed signs of alveolar hemorrhage. Serological tests showed the presence of perinuclear ANCA with anti MPO specificity. Kidney biopsy showed a necrotizing and crescentic glomerulonephritis. Pulses of methylprednisolone were given in combination with plasmapheresis. The patient further received 6 pulses of cyclophosphamide, followed by maintenance oral azathioprine. During the 15-months follow up he remained well with serum creatinine back to normal, and some residual proteinuria and hematuria ascribed to Alport syndrome. We report a young patient with the coexistence of Alport syndrome and ANCA associated vasculitis. Clinicians should be aware of the possibility of a second acquired disease in a patient with a known kidney disease, genetic in this case. This coexistence is very rare, but should be considered even if both diseases are rare, if the evolution is atypical for the single (known) primary disease. The diagnosis of the added vasculitis prompted in our case the initiation of immunosuppressive drugs, with a favourable outcome.

Renal prognosis for anti-glomerular basement membrane (GBM) glomerulonephritis is poor. The greater the amount of anti-GBM antibody binding the antigen (type IV collagen of the glomerular basement membrane), the greater the number of crescents that develop in glomeruli, resulting in progression of renal impairment. Immunofluorescence staining reveals linear IgG depositions on glomerular capillary walls. Membranous nephropathy (MN) is one of the most common causes of nephrotic syndrome in middle-aged to elderly patients. Immune complex is deposited in the sub-epithelial space of the glomerulus resulting in the development of a membranous lesion. Immunofluorescence staining reveals granular IgG depositions on glomerular capillary walls. Coexisting anti-GBM glomerulonephritis and MN are rare and, here we report a case of coexisting anti-GBM glomerulonephritis and MN with preserved renal function. There are some cases of coexisting anti-GBM glomerulonephritis and MN do not show severely decreased renal function. A 76-year-old Japanese woman presented with nephrotic syndrome, microscopic hematuria, and was positive for anti-GBM antibody. Kidney biopsy revealed linear and granular IgG depositions in glomerular capillary walls, crescent formations, and electron-dense deposits in the sub-epithelial space. She was diagnosed with anti-GBM glomerulonephritis and MN. Steroid and cyclosporine therapy achieved complete remission, and kidney function was preserved. In conclusion, coexisting anti-GBM glomerulonephritis and MN can have preserved renal function. IgG subclass of deposited anti-GBM antibody may be associated with the severity of anti-GBM glomerulonephritis. In addition, in the case of nephrotic syndrome with hematuria, we should consider the possibility of coexisting anti-GBM glomerulonephritis and MN.

In the United States non-steroidal anti-inflammatory drugs (NSAID) are freely available over-the-counter. Because of the adverse effects on the kidneys and the popularity of these drugs, unregulated use of NSAIDs is an under recognized and potentially dangerous problem. Fifteen inpatients, mean age of 15.2 ± 2.3 years (five males, 10 females), were referred to nephrology for acute kidney injury. All patients admitted to taking ibuprofen and six also consumed naproxen. None of the patients had underlying renal diseases at the time of admission. Nine patients had proteinuria and 12 had hematuria (including one with gross hematuria). One patient had nephrotic syndrome but the condition resolved spontaneously without steroids and has remained in remission for four years. Two patients required dialysis. Only one of the dialyzed patients required steroid therapy for recovery of renal function. The mean duration of hospitalization was 7.4 ± 5.5 days. The serum creatinine peaked at 4.09 ± 4.24 (range 1.2-15.3) mg/dL. All patients recovered renal function with normalization of serum creatinine to 0.71 ± 0.15 mg/dL. The estimated GFR (glomerular filtration rate) at peak of renal failure was 38.2 ± 20.5 mL/min but did improve to a baseline of 134 ± 26.2 mL/min (range 89-177, p < 0.01). However, the duration from onset to normalization of serum creatinine was 37 ± 42 days indicating that majority of patients had abnormal renal function for a prolonged period. In conclusion, NSAIDs pose a significant risk of renal failure for significant duration and as an entity may be under recognized.

A 52-year-old male chemical worker was admitted to the hospital with a history of paroxysmal microscopic hematuria for about 2 years and nocturia with gross hematuria about five times per night for 2 months. He was a nonsmoker and denied a history of any other bladder carcinogen exposure except for occasional pesticide application during agricultural work. Intravenous urogram imaging showed a mass occupying half of the bladder capacity. Cystoscopy revealed a mass over the left dome of the bladder. Cystoscopic biopsy revealed a grade 3 invasive transitional cell carcinoma with marked necrosis. From 1987 until hospital admission in 2001, the patient had worked in a company that produced the 4,4′-methylenebis(2-chloroaniline) (MBOCA) curing agent. He did not wear any personal protective equipment during work. Ambient air MBOCA levels in the purification process area (0.23–0.41 mg/m3) exceeded the U.S. Occupational Safety and Health Administration’s permissible exposure level. Urinary MBOCA levels (267.9–15701.1 μg/g creatinine) far exceeded the California Occupational Safety and Health Administration’s reference value of 100 μg/L. This patient worked in the purification process with occupational exposure to MBOCA for 14 years. According to the environmental and biologic monitoring data and latency period, and excluding other potential bladder carcinogen exposure, this worker was diagnosed as having occupational bladder cancer due to high exposure to MBOCA through inhalation or dermal absorption in the purification area. This case finding supports that MBOCA is a potential human carcinogen. Safe use of skin-protective equipment and respirators is required to prevent workers from MBOCA exposure. PMID:15929884

It is unclear whether pathologic findings on preoperative urinalysis are associated with the risk of postoperative acute kidney injury (AKI). Therefore, we performed a retrospective review to investigate this association. We assessed the clinical significance of preoperative dipstick urinalysis in a 10-year surgery cohort from a tertiary hospital in Korea. Patients without available information on perioperative serum creatinine levels or kidney injury prior to surgery were excluded. Preoperative dipstick urinalysis parameters, including albuminuria, hematuria, pyuria, and others were studied. The primary outcome was postoperative acute kidney injury. Secondary outcomes were postoperative 1-year mortality and progression of poor kidney function parameters. We enrolled 40,090 patients. The presence of dipstick albuminuria was associated with an increased risk of postoperative AKI (adjusted odds ratio 1.47 [1.29-1.66], P < .001), and the association showed a dose-response relationship. High specific gravity was significantly associated with increased risk of AKI (adjusted odds ratio 1.30 [1.04-1.63], P = .02). Furthermore, in patients with postoperative AKI, those with baseline albuminuria had a worse prognosis with regard to 1-year mortality (adjusted hazard ratio 2.81 [1.56-5.09], P < .001) and persistent renal function impairment (adjusted odds ratio 2.07 [1.21-3.46], P = .007), independent of estimated glomerular filtration rate values. Patients with baseline hematuria and pyuria also had an inferior postoperative AKI prognosis when compared to those without the urinalysis abnormalities. Baseline dipstick urinalysis may predict postoperative AKI and may be significantly associated with prognosis after surgery. (Surgery 2017;160:XXX-XXX.). Copyright © 2017 Elsevier Inc.

Gluten exacerbates IgA nephropathy in humanized mice through gliadin-CD89 interaction.

IgA1 complexes containing deglycosylated IgA1, IgG autoantibodies, and a soluble form of the IgA receptor (sCD89), are hallmarks of IgA nephropathy (IgAN). Food antigens, notably gluten, are associated with increased mucosal response and IgAN onset, but their implication in the pathology remains unknown. Here, an IgAN mouse model expressing human IgA1 and CD89 was used to examine the role of gluten in IgAN. Mice were given a gluten-free diet for three generations to produce gluten sensitivity, and then challenged for 30 days with a gluten diet. A gluten-free diet resulted in a decrease of mesangial IgA1 deposits, transferrin 1 receptor, and transglutaminase 2 expression, as well as hematuria. Mice on a gluten-free diet lacked IgA1-sCD89 complexes in serum and kidney eluates. Disease severity depended on gluten and CD89, as shown by reappearance of IgAN features in mice on a gluten diet and by direct binding of the gluten-subcomponent gliadin to sCD89. A gluten diet exacerbated intestinal IgA1 secretion, inflammation, and villous atrophy, and increased serum IgA1 anti-gliadin antibodies, which correlated with proteinuria in mice and patients. Moreover, early treatment of humanized mice with a gluten-free diet prevented mesangial IgA1 deposits and hematuria. Thus, gliadin-CD89 interaction may aggravate IgAN development through induction of IgA1-sCD89 complex formation and a mucosal immune response. Hence, early-stage treatment with a gluten-free diet could be beneficial to prevent disease.

To evaluate the effects of cystoscopy on urine cytology and additional cytokeratin-20 (CK-20) staining in patients presenting with gross hematuria. For 83 patients presenting with gross hematuria, spontaneous and instrumented paired urine samples were analyzed. Three patients were excluded. Spontaneous samples were collected within 1 hour before cystoscopy, and the instrumented samples were tapped through the cystoscope. Subsequently, patients underwent cystoscopic evaluation and imaging of the urinary tract. If tumor suspicious lesions were found on cystoscopy or imaging, subjects underwent transurethral resection or ureterorenoscopy. Two blinded uropathological reviewers (DB, KK) evaluated 160 urine samples. Reference standards were results of cystoscopy, imaging, or histopathology. Thirty-seven patients (46.3%) underwent transurethral resection or ureterorenoscopy procedures. In 30 patients (37.5%) tumor presence was confirmed by histopathology. The specificity of urine analysis was significantly higher for spontaneous samples than instrumented samples for both cytology alone (94% vs 72%, P = .01) and for cytology combined with CK-20 analysis (98% vs 84%, P = .02). The difference in sensitivity between spontaneous and instrumented samples was not significant for both cytology alone (40% vs 53%) and combined with CK-20 analysis (67% vs 67%). The addition of CK-20 analysis to cytology significantly increases test sensitivity in spontaneous urine cytology (67% vs 40%, P = .03). Instrumentation significantly decreases specificity of urine cytology. This may lead to unnecessary diagnostic procedures. Additional CK-20 staining in spontaneous urine cytology significantly increases sensitivity but did not improve the already high specificity. We suggest performing urine cytology and CK-20 analysis on spontaneously voided urine. Copyright © 2015 Elsevier Inc. All rights reserved.

We describe the presentation, diagnostic evaluation, management and outcome of female urethral trauma. All female patients treated at Harborview Medical Center between 1985 and 2001 with urethral injury were identified by International Classification of Diseases 9th revision code. Approval of the Human Subject Division was obtained and patient charts were reviewed. The Urogenital Distress Inventory Short Form, the Incontinence Impact Questionnaire Short Form and the Female Sexual Function Index were sent to the patients. A total of 25 patients (13 adults, 12 children) with a mean age of 22 years (range 4 to 67) met inclusion criteria. All had pelvic fracture related to blunt trauma. They represented 6% of all female patients treated in the same review period with pelvic fracture. Blood was seen at the introitus in 15 patients and 19 had gross hematuria. Of the injuries 9 were avulsions, 15 were longitudinal lacerations and 1 was not further specified. Primary repair was performed in 21 patients and 4 were treated nonoperatively. There were 5 patients who required secondary procedures including fistula repair in 4 and continent urinary diversion in 1. At a mean followup of 7.3 years (range 1.6 to 14.4) 9 of 21 patients (43%) had moderate or severe lower urinary tract symptoms and 8 of 13 (38%) had sexual dysfunction (FSFI score less than 26.55). Female urethral and bladder neck injury occurs with pelvic fracture, presents with gross hematuria and/or blood at the introitus, and requires operative repair for avulsions and longitudinal lacerations. These patients are at risk for significant sexual and lower urinary tract dysfunction.

Munchausen syndrome by proxy (MBP) is an extreme form of child abuse where children were unnecessarily treated or investigated for medical conditions that were falsified by their caregivers. Here the authors report a 16-year-old female with the complaints of bleeding from multiple and unusual sites, including hemoptysis, hematuria, bloody tears, and bloody nipple discharge, all of which are only witnessed by her mother. Extensive investigation revealed no organic etiologies for bleeding. The diagnosis of MBP was put by a multidisciplinary team. The diagnosis of MBP must be kept in mind in conditions where there is no underlying organic pathology in a bleeding patient.

Although Henoch-Schönlein purpura (HSP) is known to be accompanied by malignancies, cases with hepatobiliary cancer are extremely rare. A 62-year-old man with palpable purpura rapidly extending to both lower legs was admitted to our hospital. He was undergoing follow-up for cirrhosis caused by chronic hepatitis B virus infection and hepatocellular carcinoma (HCC). He had renal dysfunction with hematuria and proteinuria and abdominal pain. Based on the clinical presentation and skin biopsy findings, he was diagnosed with HSP. The administration of steroids resulted in the rapid improvement of the patient's symptoms and he was discharged 12 days after admission.

We report a case of multiple fungal renal abscesses in a 36-year-old woman with a history of diabetes and intravenous substance use disorder. The patient presented with fever and hematuria, and was found to be bacteremic and fungemic. She was initially managed with broad-spectrum antibiotics and antifungals. She remained febrile and imaging on treatment day 14 showed no improvement of the renal abscesses. Thus, a nephrectomy was performed, after which the patient defervesced and follow-up blood cultures were negative. There is a paucity of literature regarding management of multifocal fungal renal abscesses that fail to respond to medical management. Copyright © 2016 Elsevier Inc. All rights reserved.

Simple ectopic kidney was diagnosed in three dogs by means of radiography and ultrasonography. A 2-year-old castrated male Schnauzer, a 13-year-old female Schnauzer and a 9-year-old male Jindo were referred with vomiting, hematuria and ocular discharge, respectively. In all three dogs, oval-shaped masses with soft tissue density were observed in the mid to caudal abdomen bilaterally or unilaterally, and kidney silhouettes were not identified at the proper anatomic places on abdominal radiographs. Ultrasonography confirmed the masses were malpositioned kidney. The ectopic kidneys had relatively small size, irregular shape and short ureter but showed normal function on excretory urography.

Wilms tumor in a child with trisomy 13.

2000-01-01

A 4-year-old black boy with trisomy 13, a history of frequent urinary tract infections, and a horseshoe kidney with painless gross hematuria was examined. An abdominal mass was detected and surgically resected. Examination of the surgical specimen revealed a Wilms tumor. Given the concurrence of trisomy 13 and Wilms tumor and the presence of another such case in the literature, there may be just cause to suspect a locus on chromosome 13 that affects the probability of developing Wilms tumor. Given the increasingly longer survival of patients with trisomy 13, clinicians may need to be aware of the possibility of renal malignant disease in this population of patients.

For the first time, a 15-year-old boy was found to have a slight degree of proteinuria and microscopic hematuria during annual school urinalysis screening. His kidney function had already severely deteriorated. A kidney biopsy revealed tubulointerstitial nephritis (TIN) with diffuse inflammatory cell infiltration. His medical records showed his serum creatinine level to be 0.98 mg/dL two years ago, which was abnormally high considering his age. Although the etiology of slowly progressive TIN was unclear, glucocorticoid and immunosuppressant therapy improved his kidney function. This case report suggests that all doctors should recognize the reference range for the serum creatinine level in teenagers.

The intrauterine device (IUD) is the most common contraceptive method used in the world. Transuterine migration is a rare complication, accounting for 1/350 - 1/10000 insertions in the literature. We report the case of a 40-year old patient, who had had an IUD insertion 12-year before, presenting with pelvic and right lower back pain associated with intermittent hematuria and burning during urination. Radiological assessment showed calcific deposits on intra bladder IUD. The patient underwent cystostomy, without any difficulty, allowing stone and IUD extraction. A urinary catheter was left in place for 5 days and then withdrawn. The postoperative course was uneventful.

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.

Modern radiologic imaging is an aid to treatment planning for localized renal cancer, enabling characterization of mass lesions. For patients who present with advanced renal cancer, new imaging techniques enable a functional assessment of treatment response not possible using anatomic measurements alone. Multidetector CT urography permits simultaneous assessment of the kidneys and urinary tract for patients with unexplained hematuria. Both CT and MRI play a significant role in staging and follow up of patients treated for urothelial cancer. Newer imaging methods such as diffusion-weighted MRI have shown promising results for improving accuracy of staging and follow up of urothelial cancer. Copyright © 2014 Elsevier Inc.

Traumatic urethral catheterization may result in a number of serious complications. A rare occurrence is the development of a urethral pseudoaneurysm. We report the case of a 13-year-old male who required placement of a Foley catheter for an orthopedic surgical procedure. The Foley was misplaced in the bulbourethra, resulting in the development of a bulbar artery pseudoaneurysm. Profuse bleeding via the urethra was noted after removal of the catheter, and the patient experienced severe intermittent hematuria during the postoperative period. Cystoscopy revealed a pulsatile mass within the bulbourethra. Angiography confirmed a bulbar artery pseudoaneurysm, which was successfully embolized with resolution of bleeding.

Predicting acute uncomplicated urinary tract infection in women: a systematic review of the diagnostic accuracy of symptoms and signs

PubMed Central

2010-01-01

Background Acute urinary tract infections (UTI) are one of the most common bacterial infections among women presenting to primary care. However, there is a lack of consensus regarding the optimal reference standard threshold for diagnosing UTI. The objective of this systematic review is to determine the diagnostic accuracy of symptoms and signs in women presenting with suspected UTI, across three different reference standards (102 or 103 or 105 CFU/ml). We also examine the diagnostic value of individual symptoms and signs combined with dipstick test results in terms of clinical decision making. Methods Searches were performed through PubMed (1966 to April 2010), EMBASE (1973 to April 2010), Cochrane library (1973 to April 2010), Google scholar and reference checking. Studies that assessed the diagnostic accuracy of symptoms and signs of an uncomplicated UTI using a urine culture from a clean-catch or catherised urine specimen as the reference standard, with a reference standard of at least ≥ 102 CFU/ml were included. Synthesised data from a high quality systematic review were used regarding dipstick results. Studies were combined using a bivariate random effects model. Results Sixteen studies incorporating 3,711 patients are included. The weighted prior probability of UTI varies across diagnostic threshold, 65.1% at ≥ 102 CFU/ml; 55.4% at ≥ 103 CFU/ml and 44.8% at ≥ 102 CFU/ml ≥ 105 CFU/ml. Six symptoms are identified as useful diagnostic symptoms when a threshold of ≥ 102 CFU/ml is the reference standard. Presence of dysuria (+LR 1.30 95% CI 1.20-1.41), frequency (+LR 1.10 95% CI 1.04-1.16), hematuria (+LR 1.72 95%CI 1.30-2.27), nocturia (+LR 1.30 95% CI 1.08-1.56) and urgency (+LR 1.22 95% CI 1.11-1.34) all increase the probability of UTI. The presence of vaginal discharge (+LR 0.65 95% CI 0.51-0.83) decreases the probability of UTI. Presence of hematuria has the highest diagnostic utility, raising the post-test probability of UTI to 75.8% at ≥ 102

Sports anemia is a widely observed phenomenon after prolonged running. There are various factors that contribute to sports anemia, including hemodilution, exercise-induced oxidative stress, iron deficiency, gastrointestinal bleeding, hematuria, and hemolysis resulting from foot-strike and/or from compression of contracting muscles on capillaries. Until now, there has been no published report that describes the overall hematological, urinary, and fecal consequences in Asian male ultramarathoners after a 100-km (62.5-mile) ultramarathon event. A total of 25 male runners were recruited into our study. Blood was drawn 1 week before, immediately after, and then 24 hours subsequent to the race. Hematological samples were analyzed for the anemia phenomenon. Additionally, urinary and fecal samples were collected before and after the race for detection of occult blood. The blood hemoglobin and erythropoietin values of the recruited runners showed a statistically significant rise in the immediate post-race values and a rapid drop in values at 24 hours post-race. Blood concentrations of red blood cells and hematocrit were significantly lower at 24 hours post-race compared with pre-race. The white blood cell count, interleukin-6, tumor necrosis factor-alpha, high-sensitivity C-reactive protein, and ferritin all showed significant increases both immediately after and 24 hours post-race compared with pre-race hematological values. There were immediate decreases of both haptoglobin and iron, as well as an increase of total iron-binding capacity levels in post-race blood tests. For both urinary and fecal samples, there was a statistically significant difference between the pre- and post-race results in occult blood. Running a 100-km ultramarathon will induce substantial sports anemia, and oxidative stress response, hemolysis, hematuria, and gastrointestinal bleeding are typical factors that contribute to its onset.

Abstract To examine utilization and outcomes in pediatric immune thrombocytopenia (ITP) hospitalizations, we used ICD-9 code 287.31 to identify hospitalizations in patients with ITP in the 2009 HCUP KID, an all-payer sample of pediatric hospitalizations from US community hospitals. Diagnosis and procedure codes were used to estimate rates of ITP-related procedures, comorbidity prevalence, costs, length of stay (LOS), and mortality. In 2009, there were an estimated 4499 hospitalizations in children aged 6 months–17 years with ITP; 43% in children aged 1–5 years; and 47% with emergency department encounters. The mean hospitalization cost was $5398, mean LOS 2.0 days, with 0.3% mortality (n = 13). With any bleeding (15.2%, including gastrointestinal 2.0%, hematuria 1.3%, intracranial hemorrhage [ICH] 0.6%), mean hospitalization cost was $7215, LOS 2.5 days, with 1.5% mortality. For ICH (0.6%, n = 27), mean cost was $40 209, LOS 8.5 days, with 21% mortality. With infections (14%, including upper respiratory 5.2%, viral 4.9%, bacterial 1.9%), the mean cost was $6928, LOS 2.9 days, with 0.9% mortality. Septic shock was reported in 0.3% of discharges. Utilization included immunoglobulin administration (37%) and splenectomies (2.3%). Factors associated with higher costs included age >6 years, ICH, hematuria, transfusion, splenectomy, and bone marrow diagnostics (p < 0.05). In conclusion, of the 4499 hospitalizations with ITP, mortality rates of 1.5%, 21%, and 0.9% were seen with any bleeding, ICH, and infection, respectively. Higher costs were associated with clinically significant bleeding and procedures. Future analyses may reveal effects of the implementation of more recent ITP guidelines and use of additional treatments. PMID:26941022

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

Rituximab fails where eculizumab restores renal function in C3nef-related DDD.

Dense deposit disease (DDD), a C3 glomerulopathy (C3G), is a rare disease with unfavorable progression towards end-stage kidney disease. The pathogenesis of DDD is due to cytotoxic effects related to acquired or genetic dysregulation of the complement alternative pathway, which is at times accompanied by the production of C3 nephritic factor (C3NeF), an auto-antibody directed against the alternative C3 convertase. Available treatments include plasma exchange, CD20-targeted antibodies, and a terminal complement blockade via the anti-C5 monoclonal antibody eculizumab. We report here the case of an 8-year-old child with C3NeF and refractory DDD who presented with a nephritic syndrome. She tested positive for C3NeF activity; C3 was undetectable. Genetic analyses of the alternative complement pathway were normal. Methylprednisolone pulses and mycophenolate mofetil treatment resulted in complete recovery of renal function and a reduction in proteinuria. Corticosteroids were tapered and then withdrawn. Four months after corticosteroid discontinuation, hematuria and proteinuria recurred, and a renal biopsy confirmed an active DDD with a majority of extracapillary crescents. Despite an increase in immunosuppressive drugs, including methylprednisolone pulses and rituximab therapy, the patient suffered acute renal failure within 3 weeks, requiring dialysis. Eculizumab treatment resulted in a quick and impressive response. Hematuria very quickly resolved, kidney function improved, and no further dialysis was required. The patient received bimonthly eculizumab injections of 600 mg, allowing for normalization of renal function and reduction of proteinuria to <0.5 g per day. Since then, she continues to receive eculizumab. Complement regulation pathway-targeted therapy may be a specific and useful treatment for rapidly progressing DDD prior to the development of glomerulosclerosis. Our data provide evidence supporting the pivotal role of complement alternative pathway

Hereditary angiopathy, nephropathy, aneurysms, and muscle cramps (HANAC) syndrome is an autosomal dominant syndrome caused by mutations in COL4A1 that encodes the α1 chain of collagen IV, a major component of basement membranes. Patients present with cerebral small vessel disease, retinal tortuosity, muscle cramps, and kidney disease consisting of multiple renal cysts, chronic kidney failure, and sometimes hematuria. Mutations producing HANAC syndrome localize within the integrin binding site containing CB3[IV] fragment of the COL4A1 protein. To investigate the pathophysiology of HANAC syndrome, we generated mice harboring the Col4a1 p.Gly498Val mutation identified in a family with the syndrome. Col4a1 G498V mutation resulted in delayed glomerulogenesis and podocyte differentiation without reduction of nephron number, causing albuminuria and hematuria in newborns. The glomerular defects resolved within the first month, but glomerular cysts developed in 3-month-old mutant mice. Abnormal structure of Bowman’s capsule was associated with metalloproteinase induction and activation of the glomerular parietal epithelial cells that abnormally expressed CD44, α-SMA, ILK, and DDR1. Inflammatory infiltrates were observed around glomeruli and arterioles. Homozygous Col4a1 G498V mutant mice additionally showed dysmorphic papillae and urinary concentration defects. These results reveal a developmental role for the α1α1α2 collagen IV molecule in the embryonic glomerular basement membrane, affecting podocyte differentiation. The observed association between molecular alteration of the collagenous network in Bowman’s capsule of the mature kidney and activation of parietal epithelial cells, matrix remodeling, and inflammation may account for glomerular cyst development and CKD in patients with COL4A1-related disorders.

Administration of tuberculosis (TB) vaccines in participants with previous or current pulmonary TB may have the potential for causing harmful postvaccination immunologic (Koch-type) reactions. To assess the safety and immunogenicity of three dose levels of the AERAS-402 live, replication-deficient adenovirus 35-vectored TB candidate vaccine, containing three mycobacterial antigens, in individuals with current or previous pulmonary TB. We performed a phase II randomized, placebo-controlled, double-blinded dose-escalation study in an HIV-negative adult South African cohort (n = 72) with active pulmonary TB (on treatment for 1-4 mo) or pulmonary TB treated at least 12 months before study entry and considered cured. Safety endpoints included clinical assessment, flow volume curves, diffusing capacity of the lung for carbon monoxide, pulse oximetry, chest radiograph, and high-resolution thoracic computerized tomography scans. Cytokine expression by CD4 and CD8 T cells, after stimulation with Ag85A, Ag85B, and TB10.4 peptide pools, was examined by intracellular cytokine staining. No apparent temporal or dose-related changes in clinical status (specifically acute, Koch phenomenon-like reactions), lung function, or radiology attributable to vaccine were observed. Injection site reactions were mild or moderate. Hematuria (by dipstick only) occurred in 25 (41%) of 61 AERAS-402 recipients and 3 (27%) of 11 placebo recipients, although no gross hematuria was reported. AERAS-402 induced robust CD8 + and moderate CD4 + T-cell responses, mainly to Ag85B in both vaccine groups. Administration of the AERAS-402 candidate TB vaccine to participants with current or previous pulmonary TB induced a robust immune response and is not associated with clinically significant pulmonary complications. Clinical trial registered with www.clinicaltrials.gov (NCT 02414828) and in the South African National Clinical Trials Register ( www.sanctr.gov.za DOH 27-0808-2060).

To investigate the safety and efficacy of nephron-sparing surgery (NSS) in the treatment of pediatric Xp11.2 translocation renal cell carcinoma (RCC). Clinical characteristics of 9 RCC children (7 males and 2 females) with Xp11.2 translocation who received NSS between January 1973 and December 2015 were retrospectively analyzed. The mean age was 7.8years (range: 4.5-13.5years). Xp11.2 translocation RCC was found in the left side in 4 patients and right in 5. 3 tumors were located in the upper pole of the kidney, 1 in the middle dorsal, 1 in the middle ventral and 4 in the lower pole. RCC presented with painless gross hematuria in 4 patients, abdominal mass in 1, and as an incidental finding by ultrasound examination in 4 patients. The mean course of hematuria was 3months (range: 1-7months). The mean tumor diameters were 3.7cm (range: 2.2-6.9cm). All the patients received NSS with open transperitoneal approach. The mean operative time and estimated blood loss were 115min and 40ml, respectively. The time of renal pedicle clamping was 19-25min (mean: 21.5min). No complications (such as leakage of urine, prolonged drainage or secondary bleeding) were noted. No patients experienced local recurrence during the mean of 50.1-month follow-up (range: 13-117months). Intravenous urography (IVU) or contrast-enhanced CT was conducted at 6months after surgery which showed favorable kidney function in all patients. Xp11.2 translocation RCC is a predominant pathological but biologically inert type of pediatric RCC. For Xp11.2 translocation RCC sized <4-7cm in diameter and located in one pole, NSS is safe and feasible. Treatment Studies, LEVEL IV. Copyright © 2017 Elsevier Inc. All rights reserved.

Many risk factors may contribute to renal disease in patients with hemophilia A. We aimed to evaluate functional and structural renal abnormalities among a group of Egyptian children with severe and moderate hemophilia A using technetium-99m diethylene triamine pentaacetic acid ( 99m Tc-DTPA) and technetium-99 m dimercaptusuccinic acid ( 99m Tc-DMSA) scan. We also aimed to determine the relation between these abnormalities and different risk factors and disease severity. Forty male patients, 16 with severe and 24 with moderate hemophilia A, were enrolled in this study. Their mean age was 10.2 ± 4.3 years (range, 5-17 years). Full history taking, clinical examination, laboratory, and radionuclide investigations including serum creatinine, blood urea nitrogen (BUN), urine analysis, creatinine clearance, 24-hour urinary protein, 99m Tc-DTPA scan, and 99m Tc-DMSA scan were performed to all enrolled patients. Serum creatinine and BUN were normal in all patients, and corrected creatinine clearance was diminished in 2 patients. However, 99m Tc-DTPA results yielded 19 (47.5%) patients with diminished glomerular filtration rate (GFR). Moreover, it showed that 14 (35%) had obstructive uropathy, 15 (37.5%) had obstructive nephropathy, while 11 (27.5%) patients showed normal scan. One patient had atrophy of 1 kidney on 99m Tc-DMSA scan. Among our cohort, 5 (12.5%) patients were hypertensive. Microscopic hematuria was detected in 14 (35%) patients while 72.5% had proteinuria. We found an association between hematuria and hypertension with diminished GFR. Despite normal kidney functions (serum creatinine and BUN), we found a high rate of diminished GFR and obstructive uropathy and nephropathy as detected by 99m Tc-DTPA scan among children with hemophilia A.

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.

Objective Lupus flares when genetically predisposed people encounter appropriate environmental agents. Current evidence indicates that the environment contributes by inhibiting T cell DNA methylation, causing overexpression of normally silenced genes. DNA methylation depends on both dietary transmethylation micronutrients and Erk-regulated DNA methyltransferase 1 (Dnmt1) levels. We used transgenic mice to study interactions between diet, Dnmt1 levels and genetic predisposition on the development and severity of lupus. Methods A doxycycline-inducible Erk defect was bred into lupus-resistant (C57BL/6) or lupus-susceptible (C57BL/6xSJL) mouse strains. Doxycycline treated mice were fed a standard commercial diet for eighteen weeks then switched to diets supplemented(MS) or restricted(MR) intransmethylation micronutrients. Disease severity was assessed by anti-dsDNA antibodies, proteinuria, hematuria and histopathology of kidney tissues. Pyrosequencing was used to determine micronutrient effects on DNA methylation. Results Doxycycline induced modest levels of anti-dsDNA antibodies in C57BL/6 mice and higher levels in C57BL/6xSJL mice. Doxycycline-treated C57BL/6xSJL mice developed hematuria and glomerulonephritis on the MR and standard but not the MS diet. In contrast C57BL/6 mice developed kidney disease only on the MR diet. Decreasing Erk signaling and methyl donors also caused demethylation and overexpression of the CD40lg gene in female mice, consistent with demethylation of the second X chromosome. Both the dietary methyl donor content and duration of treatment influenced methylation and expression of the CD40lg gene. Conclusions Dietary micronutrients that affect DNA methylation can exacerbate or ameliorate SLE disease in this transgenic murine lupus model, and contribute to lupus susceptibility and severity through genetic/epigenetic interactions.

A 77-year-old man presented with a fever, non-productive cough, and edema formation. A laboratory analysis showed an elevated creatinine level (2.5 mg/dL), a high titer of myeloperoxidase (MPO)-anti-neutrophil cytoplasmic antibody (ANCA) (99 U/mL), positive reaction for antinuclear antibody (×320), hematuria, and massive proteinuria (3.33 g/day). A renal biopsy revealed crescentic and necrotizing glomerulonephritis (GN) with membranoproliferative GN features [double contour appearance of the glomerular basement membrane, granular deposition of immunoglobulin (Ig) G, IgM, and C3 along the capillary wall, subendothelial and subepithelial deposits with mesangial interposition]. A potential relationship between MPO-ANCA associated GN and membranoproliferative GN is discussed.

A previously healthy 32-yearold woman developed arterial hypertension, proteinuria, and hematuria (nephritic syndrome) with normal renal function and was diagnosed with post-infectious glomerulonephritis secondary to parvovirus B19 infection. The renal biopsy showed endocapillary glomerulonephritis, with positive IgG, C3, and C1q immunoreactivity in the capillary walls and ultrastructural evidence of subendothelial deposits. The diagnosis of parvovirus B19 infection was confirmed by IgG/IgM serological positivity and parvovirus DNA demonstration in both peripheral blood and kidney tissue. Glomerular involvement improved spontaneously. To be noted are the atypical signs and symptoms of our patient who, unlike previously reported cases, failed to show fever, skin rash, or affected relatives.

Aorta-Left Renal Vein Fistula Complicating an Aortic Aneurysm: Preoperative and Postoperative Multislice CT Findings

Barrier, Pierre, E-mail: p.barrier@gmail.com; Otal, Philippe; Garcia, Olivier

Fistulas complicating an abdominal aortic aneurysm (AAA) are rare, and fistulas involving the left renal vein are particularly uncommon. We highlight here a fistula between an infrarenal aortic aneurysm and a retroaortic left renal vein, revealed by left flank pain associated with hematuria and acute renal failure. The multislice CT angiography performed in this 68-year-old patient revealed communication and equal enhancement between the aorta and the left gonadic vein, suggesting the presence of a fistula. The three-dimensional VRT reconstructions presented in this case were of great value in the preoperative planning, enabling immediate visualization of this unusual feature.

Baril, Donald T; Polanco, Patricio; Makaroun, Michel S; Chaer, Rabih A

2011-04-01

Nutcracker syndrome is an entity resulting from left renal vein compression by the superior mesenteric artery and the aorta, leading to symptoms of left flank pain and hematuria. Conventional treatment has been surgical, commonly through transposition of the left renal vein to a more caudal location on the inferior vena cava. Additionally, endovascular approaches, primarily via renal vein stenting, have been described for treatment of this syndrome. We report the case of a patient with Nutcracker syndrome who underwent successful left renal vein transposition but then developed recurrent symptoms 10 months postoperatively and was successfully treated with angioplasty and stenting.

Arterioureteral fistulae are rare, but potentially life-threatening causes of bleeding. We present a case of an 82 year-old woman with refractory, transfusion-dependent bleeding from an arterial fistula to her right ureteral stump, following right radical nephrectomy for advanced renal cell carcinoma. Cystoscopy with retrograde ureteral stump embolization using Tornado (Cook Medical, Bloomington, Indiana, USA) coils plus a slurry of thrombin-soaked Gelfoam (Pfizer Inc., New York, New York, USA) was performed, which led to prompt resolution of the patient's hematuria requiring no further hospitalizations or transfusions. Retrograde insertion of coils and injection of thrombin-soaked Gelfoam can be a minimally invasive, safe, and durable alternative for controlling hemorrhage from an arterioureteral fistula to a ureteral stump.

Lymphoepithelioma-like carcinoma of the urinary bladder: A case report.

Laforga, Juan B; Gasent, Joan M

We report a case of lymphoepithelioma-like carcinoma of the urinary bladder in an elderly female patient. A 97-year old woman presented with hematuria, and an ultrasonographic urinary study showed a localized tumor in the trigone region of the urinary bladder. A transurethral resection revealed a mixed tumor formed by high-grade transitional carcinoma and lymphoepithelioma-like carcinoma that had infiltrated into the muscular propria. We describe the clinicopathological, morphological and immunohistochemical features of this tumor and briefly discuss its differential diagnosis and biological behavior.

The surgical pathology of human Lyme disease. An enlarging picture.

PubMed

Duray, P H

1987-01-01

Lyme disease is a multisystems infectious disorder caused by the spirochete, Borrelia burgdorferi. Infection occurs by ticks feeding on mammalian hosts, including humans. The distribution of the tick and spirochete is world-wide and is especially prevalent where there are large deer populations. The disease is seen in three stages. Stage I is a cutaneous rash (erythema chronicum migrans) consisting of lymphoplasmacytic infiltrates around dermal vessels. Stage II is characterized by varying forms of meningopolyradiculitis, with or without Bell's palsy or cardiac involvement (complete or incomplete heart block) and with interstitial endomyocarditis of lymphocytes and plasma cells. Lymphoplasmacellular infiltration is seen in the meninges, ganglia, and peripheral nerves. Chronic and intermittent oligoarthritis is the hallmark of stage III disease, characterized by hypertrophic synovitis, often with fibrinaceous deposits and synovial vascular occlusion. Stage III chronic dermatologic syndromes (lymphadenosis benigna cutis, acrodermatitis chronicum atrophicans) consist of cutaneous lymphoid hyperplasia and vascular changes. Neurologic demyelination syndromes also occur in stage III. Plasma cells occur in all stages, but are more prominent in stages II and III. Spirochetes can be demonstrated by silver impregnation stains in some cases.

Asymptomatic proteinuria. Clinical significance.

PubMed

Papper, S

1977-09-01

Patients with asymptomatic proteinuria have varied reasons for the proteinuria and travel diverse courses. In the individual with normal renal function and no systemic cause, ie, idiopathic asymptomatic proteinuria, the outlook is generally favorable. Microscopic hematuria probably raises some degree of question about prognosis. The kidney shows normal glomeruli, subtle changes, or an identifiable lesion. The initial approach includes a clinical and laboratory search for systemic disease, repeated urinalyses, quantitative measurements of proteinuria, determination of creatinine clearance, protein electrophoresis where indicated, and intravenous pyelography. The need for regularly scheduled follow-up evaluation is emphasized. Although the initial approach need not include renal biopsy, a decline in creatinine clearance, an increase in proteinuria, or both are indications for biopsy and consideration of drug therapy.

2015-08-01

Lymphoepithelioma-like carcinoma is an undifferentiated carcinoma with histological features similar to undifferentiated, non-keratinizing carcinoma of the nasopharynx. Lymphoepithelioma-like carcinoma of the urinary bladder is uncommon with a reported. incidence of 0.4% -1.3% of all bladder cancers. This case describes an 80 years old Egyptian male patient presented with recurrent hematuria and necroturia. Cystoscopy revealed a tumor involving the left lateral and the posterior wall of the urinary bladder. The patient underwent transurethral resection of the bladder tumor. Pathological examination showed muscle invasive lymphoepithelioma-like carcinoma associated with schistosomiasis of the urinary bladder. To the best of our knowledge the association of schistosomiasis with lymphoepithelioma-like bladder cancer was not described in the literature before this case report.

A 21-yr-old intact male walrus ( Odobendus rosmarus divergens) presented with acute onset of shifting lameness, initially associated with breeding behaviors. Further clinical signs manifested, including muscle tremors, anorexia, hematuria, and coughing. Diagnostics were limited, as the animal would not offer behaviors for voluntary sample collection. Signs were addressed with anti-inflammatories, anticonvulsants, and antibiotics. The walrus developed cluster seizures and ultimately, respiratory and cardiac arrest. Postmortem lesions included meningoencephalitis with intra- and extracellular protozoal zoites and schizonts, as well as interstitial pneumonia with intraendothelial protozoa. Immunolabeling of the protozoal organisms revealed Sarcocystis neurona. Previous S. neurona infections in an odobenid have not been reported. Protozoal infection should be considered in all species of captive marine mammals with nonspecific orthopedic, neurological, and respiratory clinical signs.

BKV was first postulated to be a potential pathogen in 1971 when it was isolated in the urine of a renal transplant recipient. The pathology of BKV is generally confined to the urinary tract. In renal transplant recipients, BKV has been associated with hemorrhagic cystitis, urethral stenosis, and interstitial nephritis. Reports of BKV infection in lung transplant recipients are limited to a few case reports in adult patients. A recent report revealed that up to 32% of adult lung transplant recipients may shed BKV in their urine without symptoms or renal dysfunction. To our knowledge, there are no published reports of pediatric lung transplant recipients with BKV-associated hematuria. We hereby report a case of BKV-induced hemorrhagic cystitis in a pediatric lung transplant recipient.

A 77-year-old man with severe septic disseminated intravascular coagulation following urinary infection was transported to our hospital. He had developed urinary retention induced by untreated prostatic hyperplasia. Immediate drainage with a Foley catheter was successfully carried out, but the hematuria progressed to life-threatening hemorrhage. Complete hemostasis was impossible by surgical treatment because the tissue around the prostatic urethra was very fragile and hemorrhagic. Organized treatments (continuous hemodiafiltration combined with polymyxin-B immobilized fiber column hemoperfusion and systemic treatment with antibiotics and coagulation factors) were commenced soon after the operation. The patient eventually recovered from the septic disseminated intravascular coagulation. This case report illustrates the risk of placement of Foley catheters in patients with severe septic disseminated intravascular coagulation.

The ifosfamide, mesna and epirubicin (IMEpi) combination is administered to 16 patients having advanced metastatic breast carcinoma as second-line chemotherapy. We observed complete response in 6%, partial response in 44% (total overall response rate of 50%), stable disease in 12% and progressive disease in the remaining 38% of the patients. The median remission duration in responders was calculated to be 9.6 months. IMEpi regimen had a tolerable toxicity profile including alopecia, nausea and vomiting, microscopic hematuria, leukopenia and neurotoxicity in which serious complications necessitating discontinuation of the chemotherapy were not encountered. It might be concluded that IMEpi chemotherapy combination is an effective alternative among schedules in the management of patients with stage IV breast carcinoma without serious side effects.

A 48-year-old married woman complaining of macroscopic hematuria and cystitis symptom was admitted to our institute. Flexible cystoscopy revealed many yellowish, nodular masses at the paries posterior of the urinary bladder, and cold-punch biopsy proved it to be amyloidosis. Serum amyloid protein A (SAA) was high, and suggested systemic amyloidosis. Renal biopsy and colon fiberscopy did not reveal any abnormalities. We therefore diagnosed a primary localized amyloidosis of the urinary bladder. Transurethral resection and dimethyl sulfoxide (DMSO) infusion therapy are used to treat amyloidosis of the urinary bladder. However there is no definite cure for amyloidosis of the urinary bladder. Therefore we selected DMSO occlusive dressing technique therapy. After 5 years of therapy, there was no evidence of a recurrence of amyloidosis.

Congenital coagulation factor VII (FVII) deficiency is a rare disorder caused by mutation in F7 gene. Herein, we reported a patient who had unexplained hematuria and vertigo with consanguineous parents. He has been diagnosed as having FVII deficiency based on the results of reduced FVII activity (2.0%) and antigen (12.8%). The thrombin generation tests verified that the proband has obstacles in producing thrombin. Direct sequencing analysis revealed a novel homozygous missense mutation p.Trp284Gly. Also noteworthy is the fact that the mutational residue belongs to structurally conserved loop 140s, which majorly undergo rearrangement after FVII activation. Model analysis indicated that the substitution disrupts these native hydrophobic interactions, which are of great importance to the conformation in the activation domain of FVIIa.

A 74 year-old woman developed a polypoid tumor of the bladder which was discovered by hematuria. Upon histological examination, the tumor was shown to be a carcinosarcoma with a weak epithelial composition confirmed by immunolabelling with keratin and was composed essentially of chondrosarcomatous material. Six months later, the patient developed metastases in the kidney, in the paravertebral muscles, and in the right para-ureteral lymph nodes. There are 55 cases of carcinosarcoma of the bladder described in the literature [3, 20, 22]. It is a tumor found more frequently in men than in women, between the ages of 33 to 83. The prognosis is very gloomy .70% death rate within 2 years), but it seems to be improved by radical cystectomy and adjuvant therapy.

A typical male looking adolescent with a legal female gender assignment presented with haematuria. Investigations led to the diagnosis of Persistent Mullerian Duct Syndrome. The condition is indeed a rare entity that needs a multidisciplinar team management. Case hypothesis: A case of Persistent Mullerian Duct Syndrome undiagnosed at birth because karyotyping was defaulted, thus resulting in a significant impact on the legal gender assignment and psychosocial aspects. Promising future implications: The reporting of this case is important to create awareness due to its rarity coupled with the rare presentation with hematuria as a possible masquerade to menstruation. There were not only medical implications, but also psychosocial and legal connotations requiring a holistic multidisciplinary management.

More than 100 firefighters lose their lives in the line of duty each year; many of these deaths are caused by cardiovascular events and underlying coronary heart disease. In addition, firefighters are at higher-than-normal risk of developing certain types of cancer. To improve health and fitness among its firefighters, the Dallas Fire-Rescue Department developed and implemented an annual wellness-fitness program in 2008. The program detected and addressed medical issues including coronary disease, hypertension, high triglyceride levels, high cholesterol, high blood glucose levels, and hematuria. Prostate, thyroid, breast, kidney, and bladder cancers were also detected. By identifying these issues, engaging the firefighters' personal physicians, and recommending individualized treatment plans, this program may have extended lives and improved the quality of life for the firefighters.

Experience with management of posterior urethral injury associated with pelvic fracture.

Coffield, K S; Weems, W L

1977-06-01

Review of records from 205 patients with pelvic fracture and hematuria revealed that 121 underwent urologic and radiographic evaluation. Of these patients 20 had severe posterior urethral injuries documented by urethrography of voiding cystourethrography: 9 underwent primary repair and 11 had delayed scrotal-inlay urethroplasty after initial cystostomy alone. Patients who underwent primary repair had a 77 per cent incidence of stricture, a 22 per cent incidence of incontinence and a 33 per cent incidence of impotency. Patients who underwent delayed closure had no incidence of stricture, incontinence or impotence. Patients in both groups had urinary tract infections. Simple cystostomy followed by delayed scrotal-inlay urethroplasty appears superior to primary realignment in the management of patients with posterior urethral injuries.

A 60-year-old female with no significant medical history presented with hematuria. A computed tomography (CT) scan revealed extensive lymphadenopathy with hypodensities in the liver and spleen, and she was referred for an 18 F-fluorodeoxyglucose ( 18 F-FDG) positron emission tomography/CT (PET/CT) study to assess for malignancy of unknown primary. PET/CT revealed extensive 18 F-FDG avid lymphadenopathy as well as innumerable intensely 18 F-FDG avid lung, liver and splenic nodules, highly concerning for malignancy. A PET-guided bone marrow biopsy of the posterior superior iliac spine revealed several non-necrotizing, well-formed granulomas, consistent with sarcoidosis. The patient was managed conservatively and remained clinically well over the subsequent 9 years of follow-up.

External ureteroneocystostomy in renal transplantation.

1985-10-01

The urologic complications of 184 consecutive renal transplants (68 living-related and 116 cadaveric) performed at Walter Reed Army Medical Center are reviewed. An anterior extravesical technique modified from Witzel, Sampson, and Lich was used to reimplant the ureter. Urologic complications occurred in 11 patients (6%): urine leak (4), obstruction (3), stricture (3), and total ureteral necrosis (1). These complications occurred in the first 115 patients; no complications have been documented in the last 69 patients. The several advantages of extravesical ureteroneocystostomy include: less operative time, avoidance of a separate cystotomy, virtually no hematuria, ability to use short ureters, no need for splints or stents, shortened Foley catheter drainage, and no interference with native ureteral function. Complications are few and become uncommon with practice.

Intraperitoneally placed Foley catheter via verumontanum initially presenting as a bladder rupture.

2011-09-01

Since urethral Foley catheterization is usually easy and safe, serious complications related to this procedure have been rarely reported. Herein, we describe a case of intraperitoneally placed urethral catheter via verumontanum presenting as intraperitoneal bladder perforation in a chronically debilitated elderly patient. A 82-yr-old male patient was admitted with symptoms of hematuria, lower abdominal pain after traumatic Foley catheterization. The retrograde cystography showed findings of intraperitoneal bladder perforation, but emergency laparotomy with intraoperative urethrocystoscopy revealed a tunnel-like false passage extending from the verumontanum into the rectovesical pouch between the posterior wall of the bladder and the anterior wall of the rectum with no bladder injury. The patient was treated with simple closure of the perforated rectovesical pouch and a placement of suprapubic cystostomy tube.

p53-Transcriptional-regulated proteins interact with a large number of other signal transduction pathways in the cell, and a number of positive and negative autoregulatory feedback loops act upon the p53 response. P53 directly controls the POMC/α-MSH productions induced by ultraviolet (UV) and is associated with UV-independent pathological pigmentation. When identifying the causative gene of dyschromatosis universalis hereditaria (DUH), we found three mutations encoding amino acid substitutions in the gene SAM and SH3 domain containing 1 (SASH1), and SASH1 was associated with guanine nucleotide-binding protein subunit-alpha isoforms short (Gαs). However, the pathological gene and pathological mechanism of DUH remain unknown for about 90 years. We demonstrate that SASH1 is physiologically induced by p53 upon UV stimulation and SASH and p53 is reciprocally induced at physiological and pathophysiological conditions. SASH1 is regulated by a novel p53/POMC/α-MSH/Gαs/SASH1 cascade to mediate melanogenesis. A novel p53/POMC/Gαs/SASH1 autoregulatory positive feedback loop is regulated by SASH1 mutations to induce pathological hyperpigmentation phenotype. Our study demonstrates that a novel p53/POMC/Gαs/SASH1 autoregulatory positive feedback loop is regulated by SASH1 mutations to induce pathological hyperpigmentation phenotype. © 2016 The Authors.

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

To determine the frecuency of complications during the management of bladder trauma and its associated factors in a third level reference Hospital. A cross-sectional study of adult patients admitted in a reference Hospital from January 2006 to June 2011 with the diagnosis of bladder trauma. We identified demographic variables, type of trauma (blunt, penetrating), diagnostic method, associated traumatisms, management of bladder traumatism, frequency of complications and mortality. Univariate analysis was performed with frequency tables, measures of central tendency and dispersion. Similarly, bivariate analysis was performed to explore the association between variables. We used chi-square test for categorical variables and Student's t test to compare quantitative variables. We reviewed 40 medical records, which met the eligibility criteria. The median age was 27 years (range 16-;67) and 85% (34 patients) were male. Twenty-nine patients (72.5%) had penetrating injuries, being mainly firearm projectile (96.55%) and 11 patients (27.5%) blunt injuries. Most patients had intraoperative diagnosis (67.5%), while 25%, 5% and 2% were diagnosed by CT-cystography, cystoscopy and voiding cystography respectively. 70% (28 patients) had intraperitoneal bladder injuries. Of the forty patients enrolled, thirty six (90%) underwent surgery, while only four (10%) received conservative management. A total of ten patients (25%) had some type of complication. The most frequent was persistent hematuria (40%) followed by surgical site infection (30%), orchitis (20%), urinary tract infection (10%), urine leakage through the operative site, or to the peritoneal cavity (10%). No mortality was detected. On the bivariate logistic regression model type of trauma, number of injuries, performance of cystostomy, use of perivesical drainage tube, chest trauma and small bowel trauma, no association was found with the presence of complications. The frequency of complications was 25%. The presence of

Cancer is a well-documented complication after kidney transplantation. Increased incidence of bladder cancer had been reported in long-term hemodialysis patients in Taiwan. Herein, the authors report a very high cumulative incidence of transitional cell carcinoma (TCC) of the urinary tract after kidney transplantation in Taiwan. The authors retrospectively reviewed the clinical data, medical records, and outcome of 730 kidney transplant (KT) recipients. The cumulative incidence of TCC was computed. The Cox regression method was used to analysis the role of potential risk factors. After a mean follow-up duration of 72.2 +/- 54.4 months, 69 cancers were diagnosed in 63 (8.6%) KT recipients. Of them, 30 cases (4.1%) were TCC. The cumulative incidence for TCC was 3.0% after 3 years of graft survival, increasing to 7.2% at 6 years and 17.5% at 10 years. Compared with the general population in Taiwan, the standardized mortality ratio was 398.4 (male, 192.6; female, 875.6). Painless gross hematuria was the cardinal initial symptom in 22 (73.3%) of the 30 KT recipients with TCC. Another 4 (13.3%) KT recipients with TCC presented with chronic urinary tract infection (UTI). Bilateral nephroureterectomy with removal of bladder cuffs was performed in 18 (60%) patients. Synchronous TCC in bilateral upper urinary tracts was confirmed in 11 (36.7%) of KT recipients with TCC. The age at the time of KT, female sex, compound analgesics usage, Chinese herb usage, and underground water intake had statistical significance as risk factors (P < 0.05). The KT recipients are at extremely high risk for TCC in Taiwan, with an incidence of 4.1%. This study indicates that hematuria and chronic UTI are the initial presentation of TCC in KT recipients. Carefully urologic screening is indicated for patients with high risk for TCC, including those with older age, compound analgesics usage, Chinese herbs usage, and underground water intake as well as women.

Objective: To explore the clinical features and expression of PLA(2)R in renal tissue of children with idiopathic membranous nephropathy. Methods: Retrospective study was performed in patients with membranous nephropathy diagnosed through renal biopsy and the follow-up time was at least half a year in Shanghai Children ' s Hospital from January 2010 to February 2017. We compared their clinicopathological and pathological findings of IMN. Indirect immunofluorescence assay was used to detect glomerular PLA(2)R expression. We analyzed the differences of clinical features between the PLA(2)R negative and positive groups. T test, rank-sum test and Fisher exact test were used. Results: Eleven cases had hematuria and proteinuria, 9 cases presented with nephrotic syndrome, and 2 cases showed isolated proteinuria. Of the 22 cases of children with IMN, 16 patients had complete remission (complete remission rate was 72.8%), and 22 patients had partial remission. The renal function of all cases was normal and in all cases the estimated glomerular filtration rate was > 90 ml/(min·1.73m(2)). Of 22 cases with IMN, 7 cases were PLA(2)R-positive in renal tissue and 15 cases were PLA(2)R-negative. The age of positive group (10 years old) was older than the negative group (6 years old)( Z= -2.483, P< 0.05) and the time of positive group (6 months) for urine protein to return to negative was longer than the negative group (2.5 months) through treatment. These differences were significantly different ( Z= -2.072, P< 0.05). Conclusions: Hematuria and proteinuria can be found in most children with idiopathic primary membranous nephropathy. Prednisone combined with immunosuppressant was effective. The positive rate of PLA(2)R in renal tissue of children with IMN was about 32%. The age of PLA(2)R positive group was older than the negative group. And the time of urine protein turning to negative in positive group was longer than that in the negative group.

Because of the increased clinical use of computed tomography (CT) for imaging the abdominal vasculature and urinary tract, there is a need for negative contrast agents. The authors undertook this study to assess the suitability of simethicone-coated cellulose (SCC), which is approved for use as an oral contrast agent in sonography, for use as a negative oral contrast agent in abdominal CT. This prospective study involved 40 adult patients scheduled to undergo abdominal CT for the evaluation of hematuria. Prior to scanning, 20 subjects received 800 mL of SCC and 20 received 800 mL of water as an oral contrast agent. Imaging was performed with a multi-detector row helical scanner in two phases, according to the abdominal CT protocol used for hematuria evaluation at the authors' institution. The first, "early" phase began an average of 15 minutes after the ingestion of contrast material; the second, "late" phase began an average of 45 minutes after the ingestion of contrast material. Blinded analysis was performed by three abdominal radiologists separately, using a three-point scale (0 = poor, 1 = acceptable, 2 = excellent) to assess the effectiveness of SCC for marking the proximal, middle, and distal small bowel. Average scores for enhancement with SCC and with water were obtained and compared. Statistical analysis was performed with a Wilcoxon signed-rank test. SCC was assigned higher mean scores than water for enhancement in each segment of the bowel, both on early-phase images (0.8-1.35 for SCC vs 0.6-1.1 for water) and on late-phase images (1.1-1.4 vs 0.81-0.96). Bowel marking with SCC, particularly in the jejunum and ileum, also was rated better than that with water in a high percentage of patients. The differences between the scores for water and for SCC, however, were not statistically significant (P > .05). SCC is effective as a negative oral contrast agent for small bowel marking at CT.

To evaluate the clinical efficacy of bladder hydrodistention and intravesical sodium hyaluronate in the treatment of interstitial cystitis (IC). Twenty-one patients with IC received intravesical sodium hyaluronate therapy under nerve block or intravenous anesthesia. Bladders were perfused with 100 cmH2O perfusion pressure and expanded for 10 min and were later injected with 40 mg/50 mL sodium hyaluronate through the catheter. After 1 h, the perfusion fluid was released. Perfusion was applied once per week, 4 to 6 times as a course of treatment. Under anesthesia, the average bladder capacity was 191.62 ± 88.67 mL, and after bladder expansion, the bladder capacity reached 425.33 ± 79.83 mL (P = .000). There were 2 suspected bladder ruptures after bladder expansion at 6.5 min and 7.2 min. After 10 min of bladder expansion, there were 19 cases of significantly gross hematuria. After treatment, the catheters of 17 patients were removed at 24 h; for the 2 cases of hematuria, catheters were removed at 72 h and for the 2 cases of suspected bladder rupture, catheters were removed after 4 days. After catheter removal, the pain threshold significantly decreased, and the maximum urinary output increased slightly. Compared with values before treatment, the day before the second injection of sodium hyaluronate, the frequency of urination decreased significantly (32.8 vs. 18.5 times/24 h), the maximum urinary output increased significantly (86.7 vs. 151.9 mL), the pain decreased significantly (8.7 vs. 3.0), and the O'Leary-Sant IC score and quality of life score were significantly decreased (30.0 vs. 17.0 and 5.9 vs. 2.4, respectively) (P = .000). Bladder hydrodistention under anesthesia for patients with severe intractable IC produces immediate effectiveness; sodium hyaluronic infusion can alleviate frequent urination and pain, and the efficacy was positively correlated with the duration of treatment.

Urinary tract infections (UTIs) are the most common bacterial infection in women. Most UTIs are acute uncomplicated cystitis caused by Escherichia coli (86%). This study was undertaken to assess the effectiveness of an association of a cranberry dry extract, D-mannose, a gelling complex composed of the exopolysaccharides produced by Streptococcus thermophilus ST10 (DSM 25246) and tara gum, as well as the 2 microorganisms Lactobacillus plantarum LP01 (LMG P-21021) and Lactobacillus paracasei LPC09 (DSM 24243) in women affected by acute uncomplicated cystitis. Thirty-three premenopausal, nonpregnant women diagnosed with acute uncomplicated cystitis were enrolled in a pilot prospective study and completed the treatment protocol. Subjects were instructed to take 2 doses per day during the first month, and then to continue with 1 sachet per day until the sixtieth day. Nitrites and leukocyte esterase on urine dipstick testing were used as indicators of cystitis, with analysis performed at enrollment, after 30 and 60 days, and after 1 month of follow-up. Typical UTI symptoms, namely dysuria, frequent voiding of small volumes, urinary urgency, suprapubic pain, and gross hematuria were scored 0 to 3 and evaluated at each visit. Positive results for the presence of nitrites and leukocyte esterase were found in 14 and 20 subjects after 30 days and in 9 and 14 women after 60 days, respectively (P<0.001). At the end of the follow-up period, positive results for nitrites and leukocyte esterase were recorded in only 4 and 3 of 24 and 19 subjects (16.7%, P=0.103; 15.8%, P=0.325, respectively), with negative results after 60 days. Typical symptoms of cystitis, specifically dysuria, frequent voiding, urgency, and suprapubic pain were significantly improved as well. No significant differences were recorded in the incidence and severity of hematuria at any visit.

Hematuria and proteinuria were detected at the peak of symptoms in a case of Ross River virus (RRV) disease. No other infective cause was identified. A renal biopsy 28 days after the onset of nephritis showed mild mesangial proliferative changes and one segmental sclerotic lesion. Immunofluorescence showed widespread linear deposition of IgG in glomerular capillary walls with similar but weak staining for IgM, complement (C3) and fibrinogen; granular deposits of IgM and C3 in several arterioles; and IgM in a few mesangial cells. No electron-dense deposits were detected, nor was RRV antigen found in the renal tissue. Anti-glomerular basement membrane antibodies were not detected in the serum. Recovery from the renal disturbance was complete within three months although rheumatic symptoms persisted for 30 months.

Secondary amyloidosis is an important complication that may have a strong influence on the prognosis of patients with rheumatoid arthritis (RA). We studied 21 RA patients with secondary amyloidosis. The two major initial signs were gastrointestinal symptoms and renal involvement. When 15 of the 21 patients were diagnosed as having secondary amyloidosis, they displayed renal involvement including proteinuria, hematuria and hypercreatininemia. The 15 patients with amyloidosis were either subjected to dialysis or died within 35 months on the average. The causes of death in 13 patients were cardiac failure, gastrointestinal bleeding and infection, which were strongly implicated with renal failure. Dialysis was applied to seven patients. Three of them were maintained with chronic dialysis. We discussed the induction-time and the method of dialysis in patients with amyloidosis secondary to RA.

We herein present the case of a patient with frank hemoptysis and hematuria, dyspnea, and cough. The patient was known to be affected by Chronic Obstructive Pulmonary Disease (COPD) and dilated cardiomyopathy with atrial fibrillation. For this latter condition, he was supposed to take 1.25 mg warfarin daily. Laboratory findings revealed very high levels of International Normalized Ratio (INR) (16), and the patient referred that he self-increased warfarin dose to 5 mg daily since 8 days before the onset of symptoms. Computed tomography scan revealed diffuse bilateral signs of alveolar hemorrhage with hydroaerial levels within emphysematous cysts. Wafarin was immediately stopped and changed with 220 mg dabigatran daily, and he was properly treated to restore a normal coagulation status. We concluded for a case of diffuse alveolar hemorrhage because of warfarin overdose.

2008-01-01

Medullary Sponge Kidney (MSK) is a benign disorder associated with renal stones in 60% of patients. Patients frequently have episodic painless hematuria but are otherwise asymptomatic unless renal calculi or infections complicate the disease. Nephrolithiasis is a relative, but frequently enforced, contraindication to space or other high performance flight. Two case reports of asymptomatic NASA flight crew with MSK and three cases of military aviators diagnosed with MSK are reviewed, all cases resulted in waiver and return to flight status after treatment and a vigorous follow up and prophylaxis protocol. MSK in aviation and space flight necessitates a highly case-by-case dependent evaluation and treatment process to rule out other potential confounding factors that might also contribute to stone formation and in order to re-qualify the aviator for flight duties.

Mutations in the genes COL4A3, COL4A4, and COL4A5 affect the synthesis, assembly, deposition, or function of the collagen IV α345 molecule, the major collagenous constituent of the mature mammalian glomerular basement membrane. These mutations are associated with a spectrum of nephropathy, from microscopic hematuria to progressive renal disease leading to ESRD, and with extrarenal manifestations such as sensorineural deafness and ocular anomalies. The existing nomenclature for these conditions is confusing and can delay institution of appropriate nephroprotective therapy. Herein we propose a new classification of genetic disorders of the collagen IV α345 molecule with the goal of improving renal outcomes through regular monitoring and early treatment.

2013-02-01

BKV has emerged as a significant pathogen in the field of transplantation, predominantly causing BKV nephropathy in renal transplant recipients and hemorrhagic cystitis in HSCT recipients. However, case reports describe more diverse complications, and we too present three unusual cases of BKV infections in pediatric renal transplant recipients. First, we describe a case of biopsy-proven renal damage secondary to BKV prior to the onset of viremia, demonstrating that BKV nephropathy can occur without preceding viremia. We also present two renal transplant recipients with persistent BK viruria, one with BKV-associated hemorrhagic cystitis and the other with microscopic hematuria. Therefore, we conclude that BKV manifestations may be more diverse than previously thought and suggest clinical utility in urine BKV qPCR testing in specific transplant recipients. © 2012 John Wiley & Sons A/S.

This article describes the pathological observations of Dioctophyma renale in dogs from the northern region of the State of Paraná, Brazil. A female, 6-year-old dog, Fila Brasileiro breed and a 16-year-old, male Poodle were diagnosed positive for D. renale during routine necropsy. Clinically, both dogs demonstrated hematuria, and the Poodle had a radiographic diagnosis of prostatic tumor, but neither had a clinical diagnosis of this infection prior to necropsy. Three giant worms were observed in the urinary bladder of the first case and one within the renal pelvis of the other dog. Histological findings were similar in both cases and represented compressive atrophy due to the presence of the nematode. Additionally, aspects of the life cycle, pathogenesis and epidemiology associated with this parasitism in Brazil are also discussed.

Extraadrenal chromaffin cell-related tumors or paragangliomas are rare, especially in the bladder, accounting for less than 1% of cases. We report a 16-year-old boy who presented with hematuria and paroxysmal headache and was found to have a prostatic growth infiltrating the urinary bladder on anatomical imaging. Iodine-131 (131I) metaiodobenzylguanidine (MIBG) whole-body scanning and subsequently gallium-68 (68Ga) DOTANOC positron emission tomography/computed tomography (PET/CT) were performed. The MIBG scan revealed a non-tracer-avid soft-tissue mass, while DOTANOC PET/CT revealed a tracer-avid primary soft-tissue mass involving the urinary bladder and prostate with metastasis to the iliac lymph nodes. He underwent surgical management; histopathology of the surgical specimen revealed a bladder paraganglioma, whereas the prostate was found to be free of tumor. PMID:26912984

More than 100 firefighters lose their lives in the line of duty each year; many of these deaths are caused by cardiovascular events and underlying coronary heart disease. In addition, firefighters are at higher-than-normal risk of developing certain types of cancer. To improve health and fitness among its firefighters, the Dallas Fire-Rescue Department developed and implemented an annual wellness-fitness program in 2008. The program detected and addressed medical issues including coronary disease, hypertension, high triglyceride levels, high cholesterol, high blood glucose levels, and hematuria. Prostate, thyroid, breast, kidney, and bladder cancers were also detected. By identifying these issues, engaging the firefighters' personal physicians, and recommending individualized treatment plans, this program may have extended lives and improved the quality of life for the firefighters.

Fanconi syndrome is a complex of multiple tubular dysfunctions of proximal tubular cells, occurring alone or in association with a variety of inherited (primary) or acquired (secondary) disorders. It is characterized by aminoaciduria, normoglycemic glycosuria, tubular proteinuria without hematuria, metabolic acidosis without anion gap and excessive urinary excretion of phosphorous, calcium, uric acid, bicarbonate, sodium, potassium and magnesium. Diabetes insipidus is a disease of collecting tubules and children mainly present with dehydration and hypernatremia. We are reporting the first case of idiopathic Fanconi's syndrome along with nephrogenic diabetes insipidus in a child who presented to us with vitamin D resistant rickets. Medline search did not reveal any case of nephrogenic diabetes insipidus (NDI) associated with idiopathic Fanconi syndrome. We hypothesized that the NDI may be due to to severe hypokalemia induced tubular dysfunction.

Myeloid sarcoma (MS) is a rare extramedullary myeloid tumour. It has been reported in various sites, including lymph node, bone, skin, soft tissue, various organs and the CNS. It may precede or occur concurrently with acute myeloid leukemia. Urinary bladder involvement is extremely uncommon. We report a 70-year-old female who had MS of the urinary bladder, presented with frank and persistent hematuria associated with lower abdominal pain. She subsequently had tumour seeding in the abdominal skin via percutaneous suprapubic catheter. Tumours from both the urinary bladder and skin showed immature cells that were immunoreactive toward LCA (focal), MPO (strong), CD99 (weak) and CD117 (weak). Summary of cases in the literature is presented. The potential of its misdiagnosis and the useful markers for the diagnosis of MS are discussed.

The association between Alport's syndrome (AS) and focal segmental glomerulosclerosis (FSGS) in the same patient is complex and rarely reported. We report a case of a 42-year-old male presenting with proteinuria, microscopic hematuria, elevated serum creatinine and hypertension with unremarkable physical examination apart from obesity. The renal biopsy showed well-established FSGS pattern of injury with mild interstitial fibrosis and tubular atrophy, while the electron microscopic examination demonstrated glomerular basement membranes (GBM) changes compatible with AS. AS can be complicated by segmental glomerular scarring, which can mimic primary FSGS, while familial FSGS can result from mutations in collagen IV network of the GBM. This overlap can complicate histopathological interpretation of renal biopsy, which should be accompanied by mutational analysis for accurate diagnosis and proper therapeutic intervention.

Sarcoma represents less than 2% of all neoplasms diagnosed or recognized in effusions. Epithelioid peripheral nerve sheath tumor is a rare tumor that is difficult to differentiate from other epithelioid tumors without the use of ancillary studies. A 39-year-old paraplegic man presented with hematuria and a bladder mass that extended to involve the pelvic peritoneum. Light microscopy using hematoxylin-eosin, Papanicolaou, and immunohistochemical stains as well as transmission electron microscopy showed features of epithelioid malignant peripheral nerve sheath tumor with rhabdoid features and an accompanying eosinophilic infiltrate. Cytologic smears confirmed the similarities between the primary tumor in the bladder and the cells in the pelvic fluid and excluded the possibility of reactive changes related to postsurgical radiation. Ancillary studies were critical in narrowing the differential diagnoses and reaching the final conclusion.

Vesicouterine fistulae as an obstetrical complication have been reported only in women with a history of cesarean. We present a patient with no such history who developed a vesicouterine fistula after vaginal delivery. A 43-year-old gravida 5 at term with no history of cesarean presented in the latent phase of labor. Gross hematuria was noted intrapartum, and a foley catheter was placed. A cystogram showed an extraperitoneal bladder perforation. The patient had urinary incontinence despite Foley catheter drainage. The diagnosis of vesicouterine fistula was made by cystoscopy and fistulogram. The patient had a successful repair at 3 months. This is a rare case of a vesicouterine fistula developing during a pregnancy with no previous cesarean. Accurate diagnosis is essential because surgical repair has an excellent outcome.

In many female patients for lower urinary tract reconstructive procedures, a suprapubic cystostomy along with perurethral catheter is required for urinary diversion. We describe a new and simple method of intraoperative suprapubic catheter placement using optical urethrotome wherein distension of bladder is not required. A total of 26 patients underwent suprapubic catheter placement intraoperatively with the aid of Sachse' optical urethrotome and its outer sheath from January 2005 to May 2008. A 16F Foley catheter could be successfully placed suprapubically in all patients with this method. There were no complications like injury to intraabdominal viscera, retropubic hematoma, hematuria, or catheter dislodgement. We describe a new method of intraoperative suprapubic catheter placement in female patients that is minimally invasive, technically safe, simple, and effective, and does not require bladder distension.

PubMed

Kiracofe, H L; Peterson, N

1975-06-01

All reported cases of massive postpartum right renal hemorrhage have involved healthy young primigravidas and blacks have predominated (4 of 7 women). Coagulopathies and underlying renal disease have been absent. Hematuria was painless in 5 of 8 cases. Hemorrhage began within 24 hours in 1 case, within 48 hours in 4 cases and 4 days post partum in 3 cases. Our first case is the only report in which hemorrhage has occurred in a primipara. Failure of closure or reopening of pyelovenous channels is suggested as the pathogenesis. The hemorrhage has been self-limiting, requiring no more than 1,500 cc whole blood replacement. Bleeding should stop spontaneously, and rapid renal pelvic clot lysis should follow with maintenance of adequate urine output and Foley catheter bladder decompression. To date surgical intervention has not been necessary.

Renal cell carcinoma (RCC) has unusual presentation affecting elderly males with a smoking history. The incidence of RCC varies while the incidence of spread of RCC to the clivus is rare. The typicality of RCC presentation includes hematuria, flank pain, and a palpable flank mass; however, RCC can also present with clival metastasis. The unique path of the abducens nerve in the clivus makes it susceptible to damage in metastasis. We report a case of a 54-year-old African American female that was evaluated for back pain, weakness, numbness, and tingling of bilateral lower extremities and subsequently disconjugate gaze and diplopia. Brain MRI confirmed metastasis to the clivus. She was started on radiotherapy and was planned for chemotherapy and transfer to a nursing home. When a patient presents with sudden unusual cranial nerve pathology, the possibility of metastatic RCC should be sought.

Urachal Tumor: A Case Report of an Extremely Rare Carcinoma.

Palla Garcia, José; Sampaio, Rita; Peixoto, Carlos

2017-01-01

The urachus is a tubular structure that connects the bladder to the allantois in the embryonic development, involuting after the third trimester. The urachus carcinoma is an extremely rare tumor that accounts for <1% of all bladder cancers. We report a case of a 46-year-old woman, with no past medical history, complaining of hematuria with 6-month duration and a physical exam and an abdominal computed topographic scan revealing an exophytic mass of 6.8 cm longer axis that grew depending on the anterior bladder wall, invading the anterior abdominal wall. Cystoscopy detected mucosal erosion. The biopsy showed structures of adenocarcinoma of enteric type. The surgical specimen showed urachus adenocarcinoma of enteric type with stage IVA in the Sheldon system and stage III in the Mayo system. This case has a 3-year follow-up without disease recurrence.

Inverted papilloma of the urinary bladder is an uncommon urothelial neoplasm that may be specially difficult to distinguish from urothelial carcinoma. Two patients with obstructive symptoms and hematuria have been studied. In the transurethral resection, accidentally, one showed a papillary lesion in the context of nodular hyperplasia of the prostate, where as the other showed a polypoid tumor of the urinary bladder Histologically, in both cases, a bladder inverted papilloma was demonstrated, originating from the surface transitional epithelium. Basal cells exhibited peripheral palisading pattern in the trabecular form. In the glandular type, Dogiel or umbrella cells into the gland-like structures, were recognized. Immunohistochemical stains for p53 and Ki-67 were negative. Umbrella cells were positive for cytokeratin 20. Two cases of bladder inverted papilloma with relevant morphological aspects are presented, which we consider useful for the differential diagnosis with urothelial carcinoma.

Churg-Strauss syndrome (CSS) also called allergic granulomatosis and angiitis is a multisystem disorder. Churg-Strauss syndrome is defined as an eosinophil-rich, granulomatous inflammation involving the respiratory tract, along with necrotizing vasculitis affecting small- to medium-sized vessels, and is associated with asthma and eosinophilia. Renal involvement in CSS varies from 26 to 88 % but is usually of mild to moderate stage, and advanced renal failure is uncommon. We encountered an unusual case of 27-year-old man with asthma and primary focal segmental glomerulosclerosis diagnosed as CSS showing myeloperoxidase anti-neutrophil cytoplasmic antibody-associated acute kidney injury with crescentic glomerulonephritis. Patient responded to steroid and cyclophosphamide. Over a follow-up of 2 months, he has no hematuria/eosinophilia and serum creatinine of 2.3 mg/dL has decreased to 1.7 mg/dL.

Minimally invasive surgery for removal of a failed renal allograft has not previously been reported. Herein, we report the first robotic trans-abdominal transplant nephrectomy (TN). A 34-year-old male with Alport's syndrome lost function of his deceased donor allograft after 12 years and presented with fever, pain over his allograft and hematuria. The operation was performed intra-abdominally using the Da Vinci Robotic Surgical System with four trocars. The total operative time was 235 min and the estimated blood loss was less than 25 cm(3). There were no peri-operative complications observed and the patient was discharged to home less than 24 h postoperatively. The utilization of robotic technology facilitated the successful performance of a minimally invasive, trans-abdominal TN. © Copyright 2014 The American Society of Transplantation and the American Society of Transplant Surgeons.

2015-08-01

Renal vein thrombosis (RVT) is an uncommon condition in adults and may be caused by endothelial damage, stasis, or hypercoagulable states. RVT is commonly identified in patients with nephrotic syndrome or malignancy. We present the case of a 57-yearold man with no past medical history who presented with a 1-month history of abdominal pain, dysuria, and hematuria. Initial laboratory studies were consistent with acute kidney injury (AKI). Imaging revealed bladder distension, enlargement of the prostate, bilateral hydronephrosis, and left renal vein thrombosis extending into the inferior vena cava. His renal failure and presenting symptoms resolved with placement of a Foley catheter and ureteral stent. The patient was discharged on anticoagulation. Here, we report a rare case of RVT that appears to have occurred as a consequence of obstructive uropathy causing massive bladder distention resulting in compression of the renal vein.

2001-01-01

We present a case of the use of alteplase for the lysis of a large urinary bladder clot. A neonate presented with respiratory failure, secondary to a left diaphragmatic hernia necessitating the need for extracorporeal membrane oxygenation (ECMO) support. On day 3 of ECMO support, hematuria was noted, and a subsequent urinary bladder ultrasound revealed a significant urinary bladder clot. Alteplase (0.5-1 mg) was instilled into the urinary bladder via a 10 French Foley catheter (Sherwood Medical, St. Louis, MO). The catheter was clamped for 1 hour, followed by irrigation with normal saline. Multiple doses of alteplase were administered, resulting in complete resolution of the bladder clot. No adverse effects were attributed to the use of the intravesical alteplase. Alteplase seems to be safe and effective for the resolution of bladder clots, thereby potentially avoiding more invasive surgical procedures.

Bladder rupture caused by postpartum urinary retention.

2008-08-01

Postpartum bladder rupture is an uncommon surgical emergency and a diagnostic challenge. A primigravida delivered a healthy newborn without complications at 39.4 weeks of gestation. The patient was admitted 80 hours postpartum with abdominal pain, oliguria, hematuria, and pain that worsened during the previous 4 hours. An inserted Foley catheter drained only a small amount of urine, and serum creatinine was elevated (3.5 mg/dL). A laparotomy was performed and revealed a 10-cm hole in the urinary bladder. The bladder was repaired and the patient was discharged 15 days after surgery. The follow-up cystoscopy revealed adequate healing of the bladder. Urinary retention can lead to serious complications, including bladder rupture. Postpartum bladder rupture due to urinary retention should be ruled out if there is a history of abdominal pain, oliguria, and elevated of serum creatinine.

[Glomerulonephritis and vasculitis as causes of arterial hypertension].

PubMed

Eicken, Sibylle; Gugger, Mathias; Marti, Hans-Peter

2012-05-01

The various types of glomerulonephritis, including many forms of vasculitis, are responsible for about 15% of cases of end-stage renal disease (ESRD). Arterial hypertension represents a frequent finding in patients suffering from glomerulonephritis or vasculitis and hypertension also serves as an indicator for these severe types of diseases. In addition, there are symptoms and signs like hematuria, proteinuria and renal failure. Especially, rapidly progressive glomerulonephritis (RPGN) constitutes a medical emergency and must not be missed by treating physicians. This disease can either occur limited to the kidneys or in the context of a systemic inflammatory disorder, like a vasculitis. If left untreated, RPGN can lead to a necrotizing destruction of glomeruli causing irreversible kidney damage within several months or even weeks. With respect to the immunologically caused vasculitis, there are - depending upon the severity and type of organ involved - many clinical warning signs to be recognized, such as arterial hypertension, hemoptysis, arthalgias, muscle pain, palpable purpura, hematuria, proteinuria and renal failure. In addition, constitutional signs, such as fever and loss of body weight may occur concurrently. Investigations of glomerulonephritis or vasculitis must contain a careful and complete examination of family history and medications used by the respective patient. Thereafter, a thorough clinical examination must follow, including skin, joints and measurement of arterial blood pressure. In addition, a spectrum of laboratory analyses is required in blood, such as full blood screen, erythrocyte sedimentation rate, CRP, creatinine, urea and glucose, and in urine, including urinalysis looking for hematuria, red cell casts and proteinuria. Importantly, proteinuria needs to be quantified by the utilization of a random urine sample. Proteinuria > 3g/d is diagnostic for a glomerular damage. These basic tests are usually followed by more specialized analyses

Background Kidney pain is a common complication in patients with autosomal dominant polycystic kidney disease (ADPKD), and data from the TEMPO 3:4 trial suggested that tolvaptan, a vasopressin V2 receptor antagonist, may have a positive effect on kidney pain in this patient group. Because pain is difficult to measure, the incidence of kidney pain leading to objective medical interventions was used in the present study to assess pain. Study Design Secondary analysis from a randomized controlled trial. Setting & Participants Patients with ADPKD with preserved kidney function. Intervention Tolvaptan or placebo. Outcomes Kidney pain events defined by objective medical interventions. Measurements Kidney pain events were recorded and independently adjudicated. Incidence of a first kidney pain event was assessed overall and categorized into 5 subgroups according to severity. Results Of 1,445 participating patients (48.4% women; mean age, 39 ± 7 [SD] years; mean estimated glomerular filtration rate, 81 ± 22 mL/min/1.73 m2; median total kidney volume, 1,692 [IQR, 750–7,555] mL), 50.9% reported a history of kidney pain at baseline. History of urinary tract infections, kidney stones, or hematuria (all P < 0.001) and female sex (P < 0.001) were significantly associated with history of kidney pain. Tolvaptan use resulted in a significantly lower incidence of kidney pain events when compared to placebo: 10.1% versus 16.8% (P < 0.001), with a risk reduction of 36% (HR, 0.64; 95% CI, 0.48–0.86). The reduction in pain event incidence by tolvaptan was found in all groups irrespective of pain severity and was independent of predisposing factors (P for interaction > 0.05). The effect of tolvaptan was explained at least in part by a decrease in incidence of urinary tract infections, kidney stones, and hematuria when compared to placebo. Limitations Trial has specific inclusion criteria for total kidney volume and kidney function. Conclusions Tolvaptan decreased the incidence of

Blind urethral catheterization in trauma patients suffering from lower urinary tract injuries.

The goals of our study were to review all cases of urethral and bladder trauma that presented to the University of California, Los Angeles (UCLA) Medical Center between January 1998 and August 2005 and determine (1) the clinical characteristics of patients with urethral and/or bladder injuries as well as the sensitivities of those clinical characteristics; (2) whether or not a blind attempt to insert a urethral catheter was performed; and (3) whether there is any evidence that a blind attempt to insert a urethral catheter worsened the initial urinary tract injury. This is a retrospective chart review. The study cohort comprised 46 patients with a mean age of 30 years, including 36 men (78.2%) and 10 women (21.8%). Bladder tears were found in 33 patients, 10 patients had urethral lacerations, and 3 patients had combined bladder and urethral lacerations. The most sensitive finding for urinary bladder or urethral injury was the presence of gross hematuria in the urethral catheter (100%, 95% confidence interval [CI] 0.63-0.89). Blinded insertion of a urethral catheter was attempted in 30 (90.9%, 95% CI 0.75-0.98) patients who suffered from urinary bladder injury, 6 (50%, 95% CI 0.26-0.87) patients who suffered from urethral injury and 1 (33%, 95% CI 0.0-0.9) patient who suffered from a combined urinary bladder and urethral injuries. We did not find evidence that a blind attempt to insert a urethral catheter worsened the initial urinary injury. Gross hematuria in the urethral catheter was the most sensitive sign for the presence of a urethral or urinary bladder injury in our study cohort, and often the only sign of such an injury. We found no evidence that a blind attempt to insert a urethral catheter in patients suffering from urethral and or urinary bladder injuries worsened the initial injury. Larger studies will be needed to determine the safety of blind urethral catheterization in patients that are suspected to suffer from a lower urological trauma. It is our

Do JJ Stents Increase the Effectiveness of Extracorporeal Shock Wave Lithotripsy for Pediatric Renal Stones?

2017-01-01

We aimed to evaluate the effects of preoperative urinary catheterization in nephrolithiasis treatment with extracorporeal shock wave lithotripsy (SWL). Patients admitted to the Department of Pediatric Surgery for renal stones between June 2012 and June 2014 were evaluated retrospectively. Patients were divided into 2 groups based on JJ stent placements. Group 1 did not receive JJ stents, while group 2 did. The recorded demographic data for each group included age, gender, stone size, location, sessions, and complications. The Elmed Complit ESWL system was used with 11-13 kV, and 1,000-1,200 shots in patients 2-4 years of age, and 11-14 kV, and 1,000-1,500 shots for patients over 4 years. In group 1, 18 sessions of SWL were performed on 8 female and 2 male children with a mean age of 4.5 (range 2-12) years and stone diameter of 9 (range 7-15) mm. The locations of the renal stones were in the upper pole in 1 patient, 7 in the lower pole, and 2 in the pelvis renalis. Postoperatively, 1 patient had hematuria, 2 had dysuria, and one had a stone in the external urethral meatus. Eighty percent of patients were stone free; there were no fragmentations in 2 patients, and 1 patient discontinued treatment. In group 2, 15 SWL sessions were performed on 5 female and 5 male children aged 4 (range 3-5) and the stone diameter was 9 (range 7-16) mm. The locations of the renal stones were in the upper pole in 6 patients, in the lower pole in 3 patients, and in the ureteropelvic junction in one patient. JJ stents were placed in all patients preoperatively. Postoperatively, 3 patients had hematuria and one had dysuria. At the end of the study, all of the patients were stone free. Statistically, there were no differences in age, gender, stone size, location, and the number of sessions. Our results indicate that SWL without preoperative ureteral stenting is an effective and safe procedure that can be carried out in the pediatric population. Preoperative JJ stenting is unnecessary in

HIV, HBV, HCV and T. pallidum infections among blood donors and Transfusion-related complications among recipients at the Laquintinie hospital in Douala, Cameroon

2014-01-01

Background Transfusion-transmissible infections (TTIs) pose a major health risk in Cameroon given the high prevalence of such pathogens and increased demands for blood donations in the local communities. This study aims at establishing the prevalence of commonly encountered TTIs among blood donors and transfusion-related complications among recipients in an urban center of Cameroon. Methods A total of 477 blood donors and 83 blood recipients were recruited by consecutive sampling at the Laquintinie Hospital in Douala (LHD), Cameroon. Serum samples from blood donors were tested by quantitative enzyme-linked immunosorbent assays (ELISA) and/or using various Rapid diagnostic test (RDT) for presence of Hepatits B (HBV) viral antigens, and antibodies to human immunodeficiency (HIV-1/2), Hepatits B (HCV) and Treponema pallidum. Recipient’s medical records were also analyzed for possible transfusion-associated complications. Results The male/female sex ratio of the blood donors was 4/1 with a mean age of 30.2 (Sd = 8.3) years. Of all blood donors, 64/467 (13.7%) were infected by at least one of the four TTIs. Infected volunteer donors represented 8.3% while infected family donors comprised 14.3% of the donor population. The prevalence of HCV, HIV, HBV and T. pallidum were 1.3%, 1.8%, 3.5%, and 8.1%, respectively. More than half of the blood recipients were female (78.3%) and the mean age was 20.6 (SD = 16.1) years. The causes of severe anemia indicative of transfusion in recipients varied with wards (postpartum hemorrhage, caesarean section, uterine or cervical lacerations, abortions, urinary tract infections, severe malaria, vaso-occlusive attacks, wounds and gastrointestinal bleeding). The most frequent complications were chills and hematuria, which represented 46.1% of all observed complications. Other complications such as nausea, vomiting, jaundice, sudden diarrhea, anxiety, tachycardia, or hyperthermia were also found in recipients. Three cases of deaths

The incidence of bladder cancer is three to four times greater in men than in women. However, women are diagnosed with more advanced disease at presentation and have less favorable outcomes after treatment. To review the literature on potential biologic mechanisms underlying differential gender risk for bladder cancer, and evidence regarding gender disparities in bladder cancer presentation, management, and outcomes. A literature search of English-language publications that included an analysis of the association of gender with bladder cancer was performed using Pubmed. Ninety-seven articles were selected for analysis with the consensus of all authors. It has been shown that the gender difference in bladder cancer incidence is independent of differences in exposure risk, including smoking status. Potential molecular mechanisms include disparate metabolism of carcinogens by hepatic enzymes between men and women, resulting in differential exposure of the urothelium to carcinogens. In addition, the activity of the sex steroid hormone pathway may play a role in bladder cancer development, with demonstration that both androgens and estrogens have biologic effects in bladder cancer in vitro and in vivo. Importantly, gender differences exist in the timeliness and completeness of hematuria evaluation, with women experiencing a significantly greater delay in urologic referral and undergoing guideline-concordant imaging less frequently. Correspondingly, women have more advanced tumors at the time of bladder cancer diagnosis. Interestingly, higher cancer-specific mortality has been noted among women even after adjusting for tumor stage and treatment modality. Numerous potential biologic and epidemiologic factors probably underlie the gender differences observed for bladder cancer incidence, stage at diagnosis, and outcomes. Continued evaluation to define clinical applications for manipulation of the sex steroid pathway and to improve the standardization of hematuria

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

PubMed Central

Macey, Matthew Ryan; Raynor, Mathew C.

2016-01-01

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

Acute renal failure after ingestion of guaifenesin and dextromethorphan.

PubMed

Small, Evan; Sandefur, Benjamin J

2014-07-01

Guaifenesin is a common nonprescription medication that has been implicated in drug-induced nephrolithiasis. Dextromethorphan, a nonprescription antitussive found in some guaifenesin-containing preparations, is increasingly recognized as a substance of abuse by many youth and young adults. Renally excreted medications known to have poor solubility in urine have the potential to precipitate when ingested in large quantity, leading to acute obstruction of the ureters and renal failure. We describe the case of a 22-year-old male who developed severe bilateral flank pain, hematuria, and oliguria after an isolated recreational ingestion of guaifenesin and dextromethorphan. The patient was found to have bilateral ureteral obstruction and acute renal failure, suspected to be secondary to precipitation of medication metabolites in the urine. This case highlights the potential for acute renal failure secondary to guaifenesin and dextromethorphan abuse. Copyright © 2014 Elsevier Inc. All rights reserved.

A 53-year-old Japanese man with systemic lupus erythematosus developed proteinuria and hematuria after a urinary stone episode. A light microscopic study of a kidney biopsy specimen demonstrated a bubbling appearance and spike formation of the basement membrane. Immunofluorescent studies revealed that there were no significant depositions of immunoglobulins, such as IgG (-), IgA (-), IgM (+/-), kappa light chain (+/-), lambda light chain (+/-), or C3 (-) in the glomerular capillary wall, though C1q was present as one-plus positive staining in mesangial areas. Electron microscopic studies showed that the thickness of the basement membrane varied from thin to thick without electron dense deposits, and that the cellular components of the podocyte were irregularly present in the basement membrane. Urinary protein decreased after the usage of prednisolone and mizoribine; however, proteinuria aggravated after an episode of urinary stone during the same treatment.

Turpentine is an oleoresin obtained from various species of pine. In turpentine poisoning, various signs and symptoms of toxicity may develop, including hematuria, renal failure, loss of vision, chest pain, vomiting, severe coughing, gastroesophageal hemorrhage, hypotension, swelling of the throat and even death. We report a case of turpentine ingestion in a 9-year-old boy. The patient was admitted to our clinic with suspected intoxication after accidentally drinking from a glass that held a turpentine oil preparation used by his father for hair care. The patient displayed no significant signs and symptoms other than bradycardia and hypotension. Laboratory investigations revealed no abnormalities. The patient was hospitalized for close monitoring and observation. During a two-and-a-half-day observation period, hypotension was corrected with administration of dopamine and intravenous fluids. In this report, we wish to draw attention to the dangerous effects of plant-derived drugs.

Case records of 7 horses diagnosed with pyelonephritis were reviewed to determine common features that might aid in diagnosis, treatment, and prognosis of this disease. All 7 horses had been admitted for evaluation of hematuria. During cystoscopy of 5 horses, hemorrhage was observed from one or both ureters. Renal biopsy of 1 horse, laboratory analysis of ureteral discharge of 2 horses, and renal ultrasonography of all horses indicated that pyelonephritis was the cause of hemorrhage. Sonographic renal changes included decreased length, increased echogenicity, abnormal outline, loss of corticomedullary distinction, pyelectasia, and focal hypoechoic or hyperechoic cortical defects. Renal hemorrhage in all horses eventually resolved but recurred in 4 of 5 horses that were followed long-term. Images Figure 1. Figure 2. Figure 3. Figure 4A. Figure 4B. Figure 4C. Figure 5A.

A 59-year-old man was admitted to hospital for investigation of a 1-year history of intermittent hematuria. He had undergone ileal ureteral replacement for left renal stones 36 years earlier. Renal ultrasonography, physical examination, abdominal plain radiography, intravenous urography, CT urography, measurement of serum levels of creatinine, urea and electrolytes, renal scintigraphy, urinalysis and urine culture. Staghorn calculi in the left kidney, with a high-lying anastomosis between the renal pelvis and the proximal ileal segment. The patient underwent percutaneous nephrolithotomy via a middle-calyx access for the large staghorn stones. After surgery, no residual calculi were found and the patient was discharged with an uneventful postoperative course. At 1 month, renal scintigraphy showed normal bilateral kidney function. The patient received potassium citrate supplementation and was followed up with 6-monthly imaging studies. At the last report, he had been stone-free for 7 months.

Fanconi's syndrome is a complex of multiple tubular dysfunctions of proximal tubular cells occurring alone or in association with a variety of inherited (primary) or acquired (secondary) disorders. It is characterized by aminoaciduria, normoglycaemic glycosuria, tubular proteinuria without hematuria, metabolic acidosis without anion gap and excessive urinary excretion of phosphorous, calcium, uric acid, bicarbonate, sodium, potassium, and magnesium. Whereas diabetes insipidus is a disease of collecting tubules and child mainly presents with dehydration and hypernatremia. Though all the cases published till date were secondary to drugs, myeloma, hematological disorders, etc., we are reporting the first case of idiopathic Fanconi's syndrome along with nephrogenic diabetes insipidus in a child who presented to us as resistant rickets. Medline search did not reveal any case of nephrogenic diabetes insipidus associated with idiopathic Fanconi syndrome. We hypothesized that the NDI may be due to of severe hypokalemia induced tubular dysfunction.

A 25-year-old male gunshot victim presented at our institution with gross hematuria following Foley catheter insertion. Computed tomography and cystogram did not show a bladder perforation, but were notable for a left ischial fracture and the presence of a bullet within the bladder. After failed attempts at retrieving the bullet with a resectoscope and loop, as well as a cystoscope and stone crusher, a 26 French nephroscope was inserted transurethrally, and the bullet was successfully engaged and removed using a Perc NCircle (Cook Medical, Bloomington, IN) grasper. The extra-peritoneal injury was managed conservatively with catheter drainage. To our knowledge, this represents the first case of successful transurethral management of a retained intravesical bullet. Such an approach may benefit patients with retained intravesical bullets or other challenging intravesical foreign bodies and may be helpful in select circumstances to spare patients from more extensive surgeries.

PubMed

Chung, H M; Yu, T J

1998-03-01

Extravesical detrusorrhaphy is a simple and safe approach to antireflux surgery; however, its use in Taiwan has seldom been reported. We report the outcomes of 15 patients (23 ureters) with primary vesicoureteral reflux who underwent extravesical detrusorrhaphy between January 1995 and April 1996, and describe the surgical technique. Overall, vesicoureteral reflux was cured in 22 of 23 ureters. Postoperative morbidity and complications were minimal. None of the patients had obstruction or significant hematuria. The discomfort related to bladder spasms during the postoperative period was subjectively decreased compared to the conventional transvesical technique. There was transient voiding inefficiency in three patients, as well as urinary retention in one, which resolved spontaneously after 4 weeks of Foley catheter drainage. Our experience showed that detrusorrhaphy is an effective way to correct vesicoureteral reflux with minimal morbidity and discomfort. Proper patient selection and strict adherence to the surgical principle are important for high success rates.

Bladder Involvement in Stage I Endometriosis.

PubMed

Brady, Paula C; Missmer, Stacey A; Laufer, Marc R

2017-08-01

Endometriosis-the ectopic implantation of endometrial-like tissue-affects 10% of adolescent females and adults. Bladder involvement, causing dysuria and hematuria, occurs in a very small number of endometriosis patients. The patient presented at age 12 years with dysuria and pelvic pain. Laparoscopy revealed stage I endometriosis. Postoperatively, she reported persistent dysuria and passage of tissue in her urine. Cystoscopy showed diffuse erythema; urine cytology revealed glandular and spindle cells suggestive of endometriosis. She was transitioned from oral contraceptives to an intranasal gonadotropin-releasing hormone agonist, with symptom resolution. Intravesicular endometriosis coinciding with stage I disease supports a mechanism of endometriosis dissemination other than direct bladder infiltration. Patients with endometriosis who complain of urinary symptoms warrant assessment, because intravesicular bladder involvement cannot be excluded using pelviscopy.

Resumo A hiperplasia angiolinfoide com eosinofilia (HALE) é considerada uma lesão vascular benigna rara que acomete, principalmente, o tecido cutâneo e subcutâneo da região de cabeça e pescoço, mas incomum na cavidade oral. Sua etiopatogenia permanece indefinida, sendo descrita como proliferação vascular reacional, malformação vascular ou neoplasia. Tem como principal diagnóstico diferencial a doença de Kimura. Este trabalho relata um caso de um paciente do sexo masculino, de 50 anos, que exibia aumento de volume nodular na mucosa do lábio superior, com 3 cm de dimensão e 7 anos de evolução. Após a biópsia excisional, o exame histopatológico mostrou lesão bem encapsulada multilobulada com proliferação de capilares sanguíneos com células endoteliais de aspecto epitelioide, infiltrado inflamatório difuso com linfócitos, plasmócitos, inúmeros eosinófilos e presença de folículos linfoides. A análise imuno-histoquímica revelou positividade para CD34 e Ki-67, o que, juntamente com o exame morfológico, direcionou o diagnóstico para HALE. PMID:29930611

[Fibroepithelial polyp of the ureter. Report of one case].

PubMed

Morales, Raúl; Manrique, Eduardo; Casanova, Rubén; Molina, Pedro; Falcón, Ramón

2004-05-01

To report the rare case of a patient with a ureteral polyp. We describe the case of a 55-year-old female patient receiving care at the Celia Sanchez Manduley University Hospital in Manzanillo, Cuba, who was fortuitously diagnosed of a fibroepithelial polyp of the right ureter during the work up and treatment of an ovarian tumor. This case is the first of its kind in this hospital after 22 years, which confirms the rarity of ureteral tumors, specifically those of benign etiology. The absence of symptoms, specifically hematuria and pain, does not correspond to the reviewed articles. The chosen treatment was exeresis of the polyp at its base and frozen biopsy, followed by re-establishment of the urinary passage, as various authors recommend. Currently the endoscopical approach is recommended for its multiple advantages. We conclude that this disease is very rare, may have a symptomatic course and the treatment of choice is surgery with very good results.

A 43-year-old female with a medical history of renal stones, hypertension, diabetes mellitus Type 2, and depression presented to her urologist with bilateral flank pain. She complained of worsening exertional dyspnea over the last several months with recent weight gain. She also endorsed night sweats and intermittent, scant hemoptysis over the past year. She denied fever, chills, nausea, vomiting, diarrhea, constipation, hematuria, or excessive joint or muscle pain. Physical examination was unremarkable. Computed tomography scan of abdomen and pelvis demonstrated bilateral nonobstructing renal stones and a 1.8 cm × 1.7 cm nodular opacity in the right lower lobe of the lung, not present on previous scan 1 year prior. Surgical wedge resection was performed and subsequent pathologic examination demonstrated a 1.2 cm × 0.6 cm × 0.5 cm soft, gelatinous well-demarcated mass in the right lower lobe wedge specimen without gross evidence of necrosis or hemorrhage confirming colloid adenocarcinoma of the lung.

2016-02-01

To date, there have been a very limited number of case reports on combined Alport syndrome (AS) and Klinefelter syndrome (KS). We herein describe the case of a 9-month-old boy diagnosed with concomitant AS and KS. KS was detected on chromosomal analysis of the amniotic fluid, and hematuria/proteinuria was identified in urinary screening at 6 months of age. Renal biopsy indicated AS, with complete deficit of the α5 chain of type IV collagen in the glomerular basement membranes. On genetic analysis for AS, de novo homozygote mutation (c.3605-2a > c) was seen in the gene encoding α5 chain of type IV collagen (COL4A5) on the X chromosomes of maternal origin. This is the first case report of combined AS and KS diagnosed during infancy, and it indicates the need to consider the concurrent existence of these two disorders in infants with urine abnormalities, even in the absence of a family history. © 2015 Japan Pediatric Society.

Renal, auricular, and ocular outcomes of Alport syndrome and their current management.

PubMed

Zhang, Yanqin; Ding, Jie

2017-09-01

Alport syndrome is a hereditary glomerular basement membrane disease caused by mutations in the COL4A3/4/5 genes encoding the type IV collagen alpha 3-5 chains. Most cases of Alport syndrome are inherited as X-linked dominant, and some as autosomal recessive or autosomal dominant. The primary manifestations are hematuria, proteinuria, and progressive renal failure, whereas some patients present with sensorineural hearing loss and ocular abnormalities. Renin-angiotensin-aldosterone system blockade is proven to delay the onset of renal failure by reducing proteinuria. Renal transplantation is a curative treatment for patients who have progressed to end-stage renal disease. However, only supportive measures can be used to improve hearing loss and visual loss. Although both stem cell therapy and gene therapy aim to repair the basement membrane defects, technical difficulties require more research in Alport mice before clinical studies. Here, we review the renal, auricular, and ocular manifestations and outcomes of Alport syndrome and their current management.

We describe an 8-year-old girl born to second-degree consanguineous parents with complaints of recurrent episodes of hematuria for 6 months. She had generalized peeling of the skin since birth and recurrent purulent cutaneous infections. The clinical presentation and histopathology of the skin biopsy specimen were consistent with the inflammatory variant of peeling skin syndrome (PSS). She also had a single ventricle with pulmonary stenosis, for which a bidirectional Glenn shunt had been placed. The renal biopsy specimen showed immunoglobulin A (IgA) nephropathy. She responded well to enalapril and steroids, with a decrease in proteinuria. IgA nephropathy has not been previously reported in PSS. Complications such as IgA nephropathy in children with PSS would help to further delineate the diverse clinical presentations and the clinical course of this rare dermatosis. We discuss the mechanisms that could explain this hitherto unreported association. © 2014 Wiley Periodicals, Inc.

The risk of deep vein thrombosis (DVT) among hospitalized children is rising.The optimal approach to DVT prophylaxis in children is unclear. This study set out to ascertain the prevalence of DVT among pediatric inpatients who neither have contraindications to nor absolute indications for prophylactic therapy. A prospective surveillance of at-risk children plus a retrospective chart review were conducted. Patients were considered to be at risk after the first 2 days of their admission. Of 1,637 patients reviewed, 198 patients met criteria; among these, 84% did not receive prophylaxis. Of 2,354 observed days at risk for nonprophylaxed patients (including days at risk prior to initiating prophylaxis among prophlyaxed patients), there were 9 DVT events, for a rate 3.82/1,000 days observed. A total of 31 patients received prophylaxis. Three of these patients experienced a DVT. One patient had a bleeding event, hematuria. These results describe patients who may be eligible for prophylaxis and should be screened for further risk factors.

An ignored cause of red urine in children: rhabdomyolysis due to carnitine palmitoyltransferase II (CPT-II) deficiency.

Carnitine palmitoyltransferase II (CPT-II) deficiency is an autosomal recessively inherited disorder involving the β-oxidation of long-chain fatty acids, which leads to rhabdomyolysis and subsequent acute renal failure. The clinical phenotype varies from a severe infantile form to a milder muscle form. Here, we report a 9-year-old boy referred to our hospital for the investigation of hematuria with a 2-day history of dark urine and malaise. As no erythrocytes in the microscopic examination of the urine and hemoglobinuria were present, myoglobinuria due to rhabdomyolysis was the most probable cause of dark urine. After excluding the other causes of rhabdomyolysis, with the help of metabolic investigations, the patient was suspected to have CPT-II deficiency, the most common cause of metabolic rhabdomyolysis. Our aim in presenting this case is to emphasize considering rhabdomyolysis in the differential diagnosis of dark urine in order to prevent recurrent rhabdomyolysis and renal injury.

2017-06-01

Thrombotic microangiopathy is a rare but severe complication of treatment with gemcitabine. Its prevalence increases because gemcitabine's indications are growing. We report four cases, which presented with common clinical and biological manifestations, i.e. high blood pressure, proteinuria and increasing plasmatic creatinine level. However, severity was not similar, hemodialysis was inconstant. There is no consensus on treatment for this condition. Stopping gemcitabine is essential. Treatment was dispensed considering the severity of the presentation: plasma exchange therapy of variable outcome, and eculizumab, which was efficient when used. It's important to note that this syndrome includes common and frequent signs in patients receiving chemotherapies. But they must encourage the research of most specific signs, such as hypertension, mechanic hemolysis signs, proteinuria or hematuria, in order to recognize thrombotic microangiopathy as early as possible to treat it precociously, and to prevent additional gemcitabine injections.

1991-12-01

Renal cell carcinoma (RCC) is a relatively uncommon cancer in renal transplant patients. From 1968 to 1987, 101 cases of RCC of native kidneys have been reported to the Cincinnati Transplant Tumor Registry. We describe here a case of metastatic RCC associated with acquired cystic kidney disease (ACKD) 15 years after successful renal transplantation. The patient presented with a subcutaneous nodule, which led to discovery of a large primary tumor in the left kidney. ACKD was present in the atrophic right kidney. The reported cases of ACKD-associated RCC in renal transplant recipients were reviewed. Most of these cases are middle-aged men with a long posttransplant course, good graft function, and usage of azathioprine and prednisone as immunosuppressive agents. ACKD can develop or persist and progress to RCC many years after successful renal transplantation. Transplant patients with flank pain, hematuria, or other suspicious symptoms should have imaging studies of their native kidneys.

Delayed Diagnosis of Vesicouterine Fistula After Treatment for Mixed Urinary Incontinence: Menstrual Cup Management and Diagnosis.

PubMed

Goldberg, Leah; Elsamra, Sammy; Hutchinson-Colas, Juana; Segal, Saya

2016-01-01

A vesicouterine fistula is a rare form of urogenital fistula, yet there is increasing prevalence in the United States because of the rising rate of cesarean deliveries. Vesicouterine fistulas have various presentations including menouria, hematuria, or urinary incontinence. A 39-year-old multiparous woman presented with urine leakage after her third cesarean delivery. She had been treated for mixed urinary incontinence with overactive bladder medications and a midurethral sling with continued complaints of urine leakage. The patient noticed her symptoms of urine leakage improved during menses when she used a menstrual cup. After confirmation of vesicouterine fistula, the patient underwent robotic-assisted surgery and her symptoms of insensible urine leakage resolved. When evaluating women with urinary incontinence and a history of cesarean deliveries, use of menstrual cup may aid in the diagnosis of vesicouterine fistula. Robotic-assisted laparoscopic repair with tissue interposition flap is an efficacious minimally invasive method for treatment of vesicouterine fistula.

Dysregulated LIGHT expression on T cells mediates intestinal inflammation and contributes to IgA nephropathy

Whether and how T cells contribute to the pathogenesis of immunoglobulin A nephropathy (IgAN) has not been well defined. Here, we explore a murine model that spontaneously develops T cell–mediated intestinal inflammation accompanied by pathological features similar to those of human IgAN. Intestinal inflammation mediated by LIGHT, a ligand for lymphotoxin β receptor (LTβR), not only stimulates IgA overproduction in the gut but also results in defective IgA transportation into the gut lumen, causing a dramatic increase in serum polymeric IgA. Engagement of LTβR by LIGHT is essential for both intestinal inflammation and hyperserum IgA syndrome in our LIGHT transgenic model. Impressively, the majority of patients with inflammatory bowel disease showed increased IgA-producing cells in the gut, elevated serum IgA levels, and severe hematuria, a hallmark of IgAN. These observations indicate the critical contributions of dysregulated LIGHT expression and intestinal inflammation to the pathogenesis of IgAN. PMID:15067315

To analyze the clinicopathological features of renal cell carcinoma (RCC) associated with Xp11.2 translocation/TFE3 gene fusions (Xp11.2 RCC) in our institution. We screened 983 RCC specimens. TFE3 immunohistochemical staining and FISH assay confirmed 22 Xp11.2 RCCs out of 65 suspicious cases. Clinicopathological and treatment outcomes of 22 patients were retrospectively analyzed. In total, 22 patients included 13 females and nine males with a mean age of 27 years. Ten patients showed gross hematuria. Treatments included surgeries, immunotherapy and molecular-targeted therapy. Seven cases were at stage III/IV and four cases had tumor thrombosis or distant metastasis. During a median follow-up of 34 months, 19 patients were alive while three died of distant metastasis. Xp11.2 RCC is rare and FISH proved a useful diagnostic tool. Surgical resection achieved favorable outcome for early disease. Adult patients at advanced stage had poorer outcomes even with postoperative adjuvant therapy.

Idiopathic Fanconi's syndrome with nephrogenic diabetes insipidus in a child who presented as vitamin D resistant rickets--a case report and review of literature.

Fanconi's syndrome is a complex of multiple tubular dysfunctions of proximal tubular cells occurring alone or in association with a variety of inherited (primary) or acquired (secondary) disorders. It is characterized by aminoaciduria, normoglycemic glycosuria, tubular proteinuria without hematuria, metabolic acidosis without anion gap and excessive urinary excretion of phosphorous, calcium, uric acid, bicarbonate, sodium, potassium and magnesium. Diabetes insipidus is a disease of collecting tubules and a child mainly presents with dehydration and hypernatremia. We report the first case of idiopathic Fanconi's syndrome along with nephrogenic diabetes insipidus (NDI) in a child who presented to us as resistant rickets. Medline search did not reveal any case of nephrogenic diabetes insipidus associated with idiopathic Fanconi's syndrome. We hypothesized that the NDI may be due to severe hypokalemia induced tubular dysfunction. The child was treated for hypophosphatemic rickets with severe metabolic acidosis and the treatment for NDI was also given. Now he has healed rickets and normal blood pH, sodium and osmolarity.

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.

To establish a simple and efficient method for establishing a mouse model of orthotopic superficial bladder cancer. C57BL/6 mice were anesthetized with sodium pentobarbital and catheterized with modified IV catheter (24 G). The mice were intravesically pretreated with HCl and then with NaOH, and after washing the bladders with phosphate-buffered saline (PBS), 100 microl (1 x 10(7)) MB49 cells were infused and allowed to incubate in the bladder for 2 h followed intravesical mitomycin C (MMC) administration. The tumor formation rate, survival, gross hematuria, and bladder weight were determined as the outcome variables, and the pathology of the bladders was observed. Instillation of MB49 tumor cells resulted in a tumor formation rates of 100% in all the pretreated groups while 0% in the control group without pretreatment. MMC significantly reduced the bladder weight as compared to PBS. We have successfully established a stable, reproducible, and reliable orthotopic bladder cancer model in mice.

We report a case with gunshot to the pelvis. The injury site was the soft tissue between the rectum and urinary bladder. Several days later, the bullet was expulsed spontaneously during voiding. In the literature, only a few case reports have described spontaneous expulsion of an intravesical bullet. A 19-year-old male was wounded on the left hip by gunshot. Radiographic examinations showed a bullet in the pelvis, which was localized in the soft tissue between the rectum and urinary bladder, with no accompanying visceral injury on abdominopelvic computerized tomography. Macroscopic hematuria was noticed after urethral catheterization. Rectosigmoidoscopy and retrograde cystoscopic examinations were both negative. The patient was monitored closely and treated conservatively with no surgical intervention. The urinary catheter was removed on the fifth postoperative day, and the bullet was expulsed spontaneously via the urethra during normal voiding three hours after catheter removal. Thereafter, a retrograde urethrography was performed, which showed no evidence of urinary tract or bladder injury.

The aim of our study was to evaluate the clinical and morphological features of primary malignant melanomas of the urinary bladder. We obtained information on five such cases from three different institutions. These were three men and two women between 52 and 76 years of age. Three tumors presented with hematuria, one with dysuria, and one was discovered incidentally on imaging studies. All were invasive to muscularis propria on transuretral resections performed for diagnosis. Neoplastic cells showed variable patterns (large cell epithelioid, small cell diffuse, storiform, or mixed) in different tumors. Pigmentation was prominent in all except one case. Each case was labeled diffusely for S-100, HMB-45, and Melan-A. Pan-cytokeratin showed a perinuclear dot-like reaction in two tumors. Three cases showed the BRAF mutation in molecular studies. Two patients were already metastatic at the time of diagnosis. Two patients died, one is alive with disease after 15 months, and two patients are disease free at 1 and 5 years of surveillance.

Obstructing urethral calculus in a woman revealed to be the cause of chronic pelvic pain.

2012-10-01

Urethral calculi are extremely rarely reported in Caucasian females and are usually associated with an anatomical abnormality such as a diverticulum or a stricture. Ureteric calculi can move to become lodged in the urethra, although this is rare in women because of their short urethral length. We present a case of a 55-year-old woman presenting with urinary retention secondary to an obstructing upper tract calculus that had moved into the urethra. Four years previously, the patient had been diagnosed with chronic pelvic pain following a primary posterior vaginal wall repair. Following treatment of the obstructing calculus, her symptoms of pelvic pain completely resolved. We report a very unusual case that highlights the importance of investigating chronic pelvic pain. This patient's symptom of vaginal pain, though highly localized, was caused by pathology elsewhere in the pelvis. Alternative diagnoses should be sought for such patients and investigation performed to detect any nonvisible hematuria.

We conducted a multicenter, retrospective cohort study of hospitalized patients with serologically proven nephropathia epidemica (NE) living in Ardennes Department, France, during 2000-2014 to develop a bioclinical test predictive of severe disease. Among 205 patients, 45 (22.0%) had severe NE. We found the following factors predictive of severe NE: nephrotoxic drug exposure (p = 0.005, point value 10); visual disorders (p = 0.02, point value 8); microscopic or macroscopic hematuria (p = 0.04, point value 7); leukocyte count >10 × 10 9 cells/L (p = 0.01, point value 9); and thrombocytopenia <90 × 10 9 /L (p = 0.003, point value 11). When point values for each factor were summed, we found a score of <10 identified low-risk patients (3.3% had severe disease), and a score >20 identified high-risk patients (45.3% had severe disease). If validated in future studies, this test could be used to stratify patients by severity in research studies and in clinical practice.

Although the second peak of the age distribution of rhabdomyosarcoma (RMS) is at adolescence, renal RMS is extremely rare at this age group. This tumor is indistinguishable from other renal tumors based on clinical and imaging findings, and the diagnosis relies on histology and immunohistochemical staining. We report a unique case of adolescent renal RMS associated with tumor thrombus extending into the inferior vena cava (IVC) and right atrium.An 18-year-old female adolescent presented with shortness of breath and palpitations, associated with right flank discomfort, and hematuria. A pleomorphic-type renal RMS with Budd-Chiari syndrome and arrhythmia induced by IVC and RA thrombosis was diagnosed. Despite complete tumor resection, the patient developed multiple lung metastases a month after surgery. Chemotherapy was recommended, but the patient declined. She died within a year of the initial operation.Adolescent renal RMS is rare and associated with poor outcome. Early aggressive multimodal therapy seems to be appropriate, in particular, in the presence of tumor thrombosis.

Emphysematous cystitis is a rare clinically entity, more commonly seen in diabetic, immunocompromised patients, which was characterized by air within the bladder wall and lumen. A 83-year-old woman was introduced to our department with fever elevation and abnormal findings of computed tomography (CT). She took orally prednisolone for autoimmune hepatitis. Pelvic CT revealed diffuse air throughout the bladder wall. Urinalysis showed combined hematuria and pyuria. Escherichia coli was detected in blood culture. Abnormal findings of complete blood count and laboratory examination included an elevated WBC count (12,200/μL), C-reactive protein (11.7 mg/dL), and creatinine (1.07 mg/dL). Cystoscopy confirmed diffuse submucosal emphysema throughout. On the basis of diagnosis with emphysematous cystitis, she was treated with antibiotics based on the results of blood culture and indwelling Foley catheter. After treatment, the improvement of inflammatory findings and submucosal emphysema on cystoscopy and CT were achieved.

2003-07-01

Vesicouterine fistula is one of the least common types of urogenital fistula, accounting for only 1-4% of all cases. We report a case of vesicouterine fistula after vacuum delivery in a woman with a history of a previous Cesarean section. The 29-year-old woman was hospitalized due to continuous serosanguinous vaginal leakage and hematuria. Transvaginal sonography demonstrated the presence of a fistulous tract between the uterus and the bladder. Cystoscopy demonstrated a small opening in the posterior bladder wall and a cystogram revealed a fistulous tract between the posterior portion of the bladder and the uterine cavity. Since the patient could not tolerate her symptoms, we decided to close the fistulous tract surgically. The fistulous tract was excised and the bladder and uterus were closed primarily. The bladder was drained with a Foley catheter for 12 days and subsequent follow-up of the patient has demonstrated urinary continence. Copyright 2003 ISUOG. Published by John Wiley & Sons, Ltd.

We report a new α-Galactosidase A (αGal-A) mutation in a 39-year-old Korean born, male Fabry disease patient. Fabry disease is a devastating, progressive inborn error of metabolism caused by X-linked genetic mutations. In this case, the first clinical symptom to occur was in childhood consisting of a burning pain originating in the extremities then radiating inwards to the limbs. This patient also stated to have ringing in his ears, angiokeratomas on his trunk, and cornea verticillata. He visited an outpatient cardiologist due to intermittent and atypical chest discomfort at the age of 39. Electrocardiographic and echocardiographic examination showed left ventricular hypertrophy. A physical examination revealed proteinuria without hematuria. The patient's plasma αGal-A activity was markedly lower than the mean value of the controls. After genetic counseling and obtaining written informed consent, we identified one hemizygous mutation in exon 4 of galactosidase alpha, c.617T>C (p.Leu206 Pro). He was eventually diagnosed as having Fabry disease.

In recent years, tonsillectomy and steroid pulse (TSP) therapy have been widely performed in Japan. However, there is no consensus about the treatment protocol and indication. In this retrospective analysis, we compared patients who received tonsillectomy plus intermittent steroid pulse (SP) therapy three times in 6 months (ISP group, n = 44) with patients who received tonsillectomy plus 3 weeks of consecutive SP therapy (CSP group, n = 46) within 1 year after renal biopsy. These two different protocols were performed at two different institutions. We analyzed the clinical and histological background and clinical remission (CR), defined as disappearance of urine abnormalities at 18 months after starting treatment. Before treatment, there was no significant difference in the clinical findings except for sex between the two groups. In ISP group and CSP group, mean estimated glomerular filtration rate was 82.1 ± 20.9 and 85.9 ± 19.1 ml/min/1.73 m(2), median proteinuria was 0.55 and 0.56 g/day, and median urinary red blood cells were 20 (10-20) and 20 (6-30)/high power filed. The histological (H) grade was lower in the CSP than the ISP group (p = 0.022). The remission rate of proteinuria, hematuria, and rate of CR by the Kaplan-Meier method and logrank test were significantly higher in the CSP group than in the ISP group (CSP vs. ISP group; proteinuria: 97.8 vs. 77.3 %, p < 0.001, hematuria: 97.8 vs. 75.0 %, p = 0.005, CR: 95.6 vs. 63.6 %, p < 0.001). In the Cox proportional hazard model (forced entry), SP protocol and proteinuria before treatment were significantly associated with CR [SP protocol: hazard ratio (HR) 2.50, 95 % confidence interval (CI) 1.46-4.30, p = 0.001, proteinuria: HR 0.81, 95 % CI 0.68-0.96, p = 0.013)]. However H-grade was associated with remission of proteinuria (H-grade: hazard ratio (HR) 0.56, 95 % confidence interval (CI) 0.37-0.85, p = 0.006), and this result meant histological bias affected the remission of proteinuria.

Objective: To summarize the clinical data of pre-implantation biopsy donors in our hospital and explore the clinical characteristics of those donors in pathological high-risk, and to provide references for the selective histological evaluation of extended criteria donor kidneys. Methods: We retrospectively reviewed the clinical data and pre-implantation renal pathologic score of donors from January 1, 2015 to May 1, 2017.During this period, 247 cases of donation after citizen's death (DCD) occurred.After clinical evaluation and selective machine perfusion( Lifeport) evaluation, 30 cases of pre-implantation pathological evaluation were performed.According to Remuzzi scores, donors were divided into low-risk and high-risk group.Nine cases of low-risk group (bilateral kidney's Remuzzi score ≤3) and 16 cases of high-risk group (bilateral or unilateral kidney's Remuzzi score ≥4, severe glomerular micro-thrombi or severe tubular necrosis) were included.Five cases of donors were excluded due to only unilateral renal pathological result available.Both high-risk and low-risk groups' clinical data, including sex, age, height, body weight, body mass index, proteinuria, hematuria, urinary glucose, baseline or admission serum creatinine, serum creatinine before procurement, history of hypertension and/or diabetes mellitus, cardiopulmonary resuscitation or not, with or without the history of shock, urine output prior to acquisition, macroscopical manifestations of donor kidney, cause of death were statistically analyzed. Results: The donors' baseline serum creatinine/upper limit of normal serum creatinine range in high-risk group were significantly higher than that in low-risk group [(129.8±42.2)% vs(92.4±30.5)%, P =0.029]. The poor macroscopical manifestations of donor kidneys were significantly more frequent in high-risk group than that in low-risk group (12/16 vs 0/9, P = 0). No significant differences between two groups were found regarding their age, height, weight

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.

A 68-year-old man who developed MPO-ANCA-associated glomerulonephritis during propylthiouracil (PTU) treatment is reported. In 1986, he was diagnosed as having interstitial pneumonitis. Although he tested positive for antinuclear antibody and rheumatoid factor, he had no symptoms and was followed up without therapy. Five years later, the diagnosis of Graves's disease was made after complaints of body weight loss, diplopia and exophthalmos. Tests showed positivity for anti-thyroid stimulating hormone (TSH) receptor antibody, antithyroidperoxidase antibody and antithyroglobulin antibody. He was treated with PTU and prednisolone for four years. In November 1995, hematuria and proteinuria developed, and renal function deteriorated rapidly. A renal biopsy revealed crescentic glomerulonephritis and the serum titer of MPO-ANCA was markedly elevated. He was treated with a high dose of prednisolone and cyclophosphamide. Although the serum creatinine level gradually decreased, irreversible renal dysfunction persisted. In this patient, the presence of various autoantibodies had been recognized for several years before MPO-ANCA-associated glomerulonephritis developed. Polyclonal B-cell activation and PTU treatment may have played a role in the pathogenesis of MPO-ANCA-associated glomerulonephritis.

We report our experience with a preterm infant with severe hemolytic jaundice who required exchange transfusion just after birth. The patient was negative for alloimmune hemolysis as a result of maternal-fetal blood type incompatibility, and tests for inherited defects in erythrocyte metabolism, membrane function, and hemoglobin synthesis were normal. We also performed a bone marrow examination, but could not identify the cause of hemolysis. The patient had several other complications, including porencephaly, epilepsy, elevated serum levels of creatine kinase, and persistent microscopic hematuria. Later, we detected a genetic mutation in COL4A1, which was recently found to be associated with hemolytic anemia. We therefore believe that all of the patient's clinical features, including hemolytic anemia, were due to the mutation in COL4A1. Genetic testing for COL4A1 mutations is recommended in neonates who exhibit hemolytic disease of unknown etiology, especially when other complications compatible with COL4A1-related disorders are present.

The Southwest Oncology Group did a limited institutional pilot study of the combination of doxorubicin and ifosfamide in the treatment of previously treated adult patients with acute leukemia. Thirty-four patients received one or two courses of the combination. All patients had received prior chemotherapy and 32 had received prior anthracycline chemotherapy. Three patients died before their responses could be fully evaluated. Fourteen patients achieved complete remission (41%) and one patient achieved partial remission. The complete remission rate was 27% for patients with acute myeloblastic leukemia (myelomonoblastic leukemia, monoblastic leukemia, and erythroleukemia) and 89% for patients with acute lymphocytic and undifferentiated leukemia (ALL). Toxic effects included severe hematologic reactions in 33 of 34 patients, hematuria in six patients, altered sensorium in one patient, and congestive heart failure in one patient. The safety of the combination was established and toxic side effects of this therapy were tolerable. The 89% complete remission rate for previously treated patients with ALL suggests that the combination of doxorubicin and ifosfamide may be particularly effective in ALL.

Primary or metastatic malignant melanoma can mimic benign blue nevus in rare cases, making the diagnosis challenging. Herein, we report an exceptionally rare case of blue nevus-like melanoma and its blue nevus-like metastasis which was detected by catheterized urine cytology. The patient presented with blue-colored papuloplaques on his temple which were diagnosed as blue nevus-like melanoma on punch biopsies. While he was admitted for administration of chemotherapy, hematuria was detected. Catheterized urine cytology revealed singly scattered oval to spindle-shaped pigmented cells with a moderate degree of variation in shape and size. Many of them had small nuclei with indiscernible to inconspicuous nucleoli while only a few cells showed nuclear enlargement and nuclear hyperchromasia, which could be diagnostic pitfalls. Most of the cells on the smear were positive for HMB45 immunostaining, which confirmed the diagnosis of metastatic blue nevus-like melanoma. To the best of our knowledge, the present case is the first report describing cytomorphologic findings of blue nevus-like metastasis of melanoma in the urine specimen.

IgM nephropathy; can we still ignore it.

IgM nephropathy (IgMN) is a relatively less recognized clinico-immunopathological entity in the domain of glomerulonephritis , often thought to be a bridge between minimal change disease and focal segmental glomerulosclerosis. Directory of Open Access Journals (DOAJ), Google Scholar, Pubmed (NLM), LISTA (EBSCO) and Web of Science has been searched. IgM nephropathy can present as nephritic syndrome or less commonly with subnephrotic proteinuria or rarely hematuria. About 30% patients respond to steroids whereas others are steroid dependent / resistant. They should be given a trial of Rituximab or stem cell therapy. IgM nephropathy (IgMN) is an important and rather neglected pathology responsible for renal morbidity in children and adults in developing countries as compared to developed nations with incidence of 2-18.5% of native biopsies. Abnormal T-cell function with hyperfunctioning suppressor T-cells are believed to be responsible for this disease entity. Approximately one third of the patients are steroid responders where as the remaining two thirds are steroid resistant or dependent. Therapeutic trials including cell therapies targeting suppressor T-cells are required.

A case of congenital renal arteriovenous fistula (AVF) complicating pregnancy with gross hematuria was managed successfully by superselective embolization with metallic coils. The patient was in the first trimester of her pregnancy at 12 weeks of gestation. The AVF was detected by color Doppler sonography and confirmed by renal arteriography. Because of its easy accessibility and absence of irradiation, ultrasound is the first choice for pregnant patients. Color Doppler ultrasound is effective in diagnosing AVF, and it is also helpful in the long-term followup after treatment. The cirsoid-type renal congenital arteriovenous fistula has a characteristic sonographic appearance with a cluster of tubular anechoic structures in the kidney, which produce continuous turbulent high-velocity flow signals and a burr-like boundary flow spectrum. When the sonographic features are present, the diagnosis of renal AVF should be made, after which renal arteriography can be performed to confirm it. Selective embolization provided a safe and effective treatment with minimal damage to the parenchyma and without compromising renal function.

A previously healthy 15-year-old girl was evaluated following five episodes of reddish urine discoloration after walking for approximately 30 min on a smooth roadway. In each episode, the discoloration lasted for four to five urinations and followed by normal urine dipstick tests. No other exercise-produced urine discoloration and no other symptoms were reported. Laboratory evaluation during the episodes revealed a reddish urine sample with 3+ hemoglobin/myoglobin and absence of hematuria. Full blood count, serum creatinine, liver function tests, and electrolyte levels were all within normal limits. Myoglobulinuria was excluded, since muscle enzymes were within normal limits. Blood smear analysis showed mild anisopoikilocytosis with stomatocytes and ovalocytes, leading to extended evaluation for erythrocyte disorders. This case is interesting in that the hemoglobinuria occurred after mild walking and was accompanied by erythrocyte morphological changes. This quiz discusses the differential diagnosis of hemoglobinuria with particular reference to the conditions of appearance (after walking) and emphasizes the importance of step-by-step investigations to reach a definitive diagnosis.

Diagnostic dilemma: Epstein-Barr virus (EBV) infectious mononucleosis with lung involvement or co-infection with Legionnaire's disease?

PubMed

Cunha, Burke A; Gian, John

Hospitalized adults with fever and "pneumonia" can be a difficult diagnostic challenge particularly when the clinical findings may be due to different infectious diseases. We recently had an elderly female who presented with fever, fatigue and dry cough with elevated serum transaminases and lung infiltrates. The diagnosis of Epstein-Barr virus (EBV) infectious mononucleosis (IM) was made based on a positive Monospot test, elevated EBV VCA IgM titer, and highly elevated EBV viral load. Her chest infiltrates were not accompanied by hilar adenopathy which may occur with EBV IM. Her dry cough persisted and she developed abdominal pain. Legionnaire's disease was considered because she had extra-pulmonary findings characteristic of Legionnaire's disease, e.g., relative bradycardia, abdominal pain, hyponatremia, hypophosphatemia, elevated ferritin levels, microscopic hematuria. Legionella titers were negative, but Legionella (serogroup 1) urinary antigen was positive. We present a diagnostic dilemma in an elderly female with both Legionnaire's disease and Epstein-Barr virus infectious mononucleosis with pulmonary involvement. Copyright © 2016 Elsevier Inc.

Abstract Onyx is an emerging treatment modality for visceral vascular malformations, especially in cases in which delicate nidal penetration of the arteriovenous malformation (AVM) is desired. A computed tomography (CT) image presentation of hyperdense striations along the renal medulla secondary to the tantalum powder has not been previously reported. A 65-year-old woman presented to our institution with intermittent gross hematuria and left flank pain for 10 days. Both CT and conventional angiographies confirmed cirsoid-type renal AVM, which was successfully treated with Onyx. Follow-up CT after treatment revealed presence of hyperdense striations along the renal medulla, which resolved during later image follow-up. Despite its frequent usage in neural intervention, the application of Onyx in visceral AVM is gradually gaining interest, especially in cases in which delicate nidal penetration of the AVM is desired. Renal hyperdense striation sign should be recognized to avoid confusion with embolizer migration, and further studies in patients with renal function impairment may be helpful in understanding its influence of renal function.

Percutaneous nephrolithotomy (PNL) is an effective procedure for the treatment of patients with large or complex stones. PNL is challenging in anomalous kidneys, certain patients, such as those with renal ectopia. It is unable to undergo PNL in conventional technique safely in these cases. We presented a case report of laparoscopic-assisted PNL via direct pelvic puncture in a pelvic kidney stone and discussed previous published literature. A 49-year-old man presented with right lower quadrant pain and hematuria. Intravenous pyelography and three-dimensional computerized tomography revealed an opaque 2.7 × 1.7 cm pelvis renalis stone in a right side ectopic pelvic kidney with grade III hydronephrosis. Laparoscopic-assisted tubeless PNL was performed to remove the calculus. Laparoscopic-assisted PNL as a minimally invasive therapy in ectopic kidney has many advantages. Our case showed that, in pelvic ectopic kidney with pelvic stones greater than 1.5 cm in size, laparoscopic-assisted PNL via direct pelvis puncture is a safe and effective technique.

Urinary schistosomiasis remains a significant burden for Africa and the Middle East. Success of regional control strategies will depend, in part, on what influence local environmental and behavioral factors have on individual risk for primary infection and/or reinfection. Based on experience in a multi-year (1984–1992), school-based Schistosoma haematobium control program in Coast Province, Kenya, we examined risk for infection outcomes as a function of age, sex, pretreatment morbidity, treatment regimen, water contact, and residence location, with the use of life tables and Cox proportional-hazards analysis. After adjustment, location of residence, age less than 12 years, pretreatment hematuria, and incomplete treatment were the significant independent predictors of infection, whereas sex and frequency of water contact were not. We conclude that local physical features and age-related factors play a predominant role in S. haematobium transmission in this setting. In large population-based control programs, treatment allocation strategies may need to be tailored to local conditions on a village-by-village basis. PMID:16837713

Renal cell carcinoma (RCC) in children and young adults is rare and pathologically problematic. RCC can be either hereditary or sporadic and has a guarded prognosis because appropriate management has not been established. A case of RCC in an 11-year-old is reported. The clinical presentation was a right abdominal mass, hematuria, urinary tract infection, and wasting. Radio-logically, the mass was found within the right kidney with calcification and paraaortic lymphadenopathy. The postsurgical diagnosis was Wilms' tumor stage T4N2M0. On gross inspection, the tumor was ill defined, extending across Gerota's fascia and into the ureter lumina. Microscopically, the tumor consisted of malignant epithelial cells with clear and eosinophilic cytoplasm in nested, papillary, and alveolar configuration. Hyaline nodules, psammoma bodies, vascular invasion, capsular invasion, and extension into the ureter were also found. Immunohistochemically, the cells showed strong nuclear immunoreactivity for TFE3. We concluded that this case was an RCC associated with Xp11.2 translocation/TFE3 fusion, Fuhrman grade 3, stage IV.

Introduction. The recently recognized renal cell carcinomas associated with Xp11.2 translocations are rare tumors predominantly reported in children. Chromosome Xp11.2 translocation results in gene fusion related to transcription factor E3 (TFE3) that plays an important role in proliferation and survival. Case Report. Herein, we present two cases of a TFE3 translocation-associated RCC in young female adults, one detected incidentally and the other one presenting with gross hematuria. Tumor is characterized by immunohistochemistry and a literature review with optimal treatment regimen is presented. Discussion. Xp11.2 translocation RCCs in adult patients are associated with advanced stages, large tumors, and extracapsular disease and usually have an aggressive clinical course. Conclusion. In TFE3 RCC, the genetic background may not only contribute to tumorigenesis, but also determine the response to chemotherapy and targeted therapy. Therefore it is necessary to diagnose this tumor entity accurately. Because of the small number of TFE3 gene fusion-related renal tumors described in the literature, the exact biologic behavior and impact of current treatment modalities remain to be uncertain.

Xp11.2/TFE3 translocation renal cell carcinoma (RCC), a recently classified distinct subtype, is a rare tumor that usually affects children and adolescents. The morphology and biological behavior are not widely recognized, Xp11.2 translocation RCC is suggestive of early metastases despite the small tumor size. The definitive diagnosis requires the evidence of several different reciprocal translocations involving the TFE3 gene located on chromosome Xp11.2. Here, we present a case of Xp11.2 translocation RCC in an 18-yearold male. He was referred to our hospital because of a right renal tumor with macroscopic hematuria and right flank colic. The radiographic evaluation including magnetic resonance imaging (MRI) suggested it to be a typical papillary renal cell carcinoma or benign renal tumor. He underwent laparoscopic nephrectomy against the repeat symptom in spite of small tumor (3.5 cm in diameter). The immunohistochemical study revealed nuclear staining for TFE3 protein in the cancer cells. The urologic and radiologic outcomes were satisfactory after more than 1 year of follow-up.

One hundred one patients with renal allografts were studied by two independent observers using duplex Doppler sonography (DDS) and color-coded Doppler sonography (CCDS). In all patients, single or multiple percutaneous needle biopsies of the transplant had been performed 1 to 30 days before. In 6 patients CCDS following the biopsy demonstrated an area of combined red and blue color-coded blood flow within the renal parenchyma (n = 5) or within the sinus (n = 1); the Doppler waveform was abnormal in these areas with signals above and below the zero line indicating turbulent blood flow. Consecutive intraarterial digital subtraction angiography (DSA) revealed the presence of an arteriovenous fistula (n = 4) or of a pseudoaneurysm (n = 2). In one patient, gross hematuria with obstruction of the bladder occurred as a complication of a pseudoaneurysm within the renal sinus; the bleeding could not be stopped by embolization of the lesion and the kidney had to be removed. DDS demonstrated the lesion in only one of the six patients. Thus, CCDS is the method of choice for noninvasive detection of vascular lesions due to percutaneous biopsy.

The insertion of a double J catheter (DJ) has widespread, becoming a usual procedure and standard of care in urology. Despite its relative simplicity it is not free from intraoperative risks or problems during the weeks after the implant. Conversely, despite great advances in design of these catheters the ideal material has not been discovered yet, one that is perfectly biocompatible with urine and avoids completely the advent of complications. The range of problems associated with DJs is variable: from mild self-limited dysuria or hematuria to more complex situations with higher risk, such as catheter migration, complete calcification, breakage, obstruction and renal unit loss. The treatment of theses complications must combine maximal efficacy for their resolution with the least possible surgical aggression. Accordingly, the different options of endourological approach become very important and they are the cornerstone for the treatment of the complications associated with ureteral catheters. The objective of this review is to present the main complications derived from the insertion of a DJ, their diagnosis, prevention and treatment, focusing mainly in the different endourological techniques.

The purpose of this study was to assess the efficacy of a modified percutaneous nephrostomy procedure for grade III-IV hydronephrosis in neonates. Eleven neonates (five girls, six boys) with a mean age of 13.7days±9.9 (SD) (range, 4-28days) with pronounced hydronephrosis had percutaneous nephrostomy using a modified procedure. In all patients, percutaneous nephrostomy was performed with a trocar catheter under ultrasound guidance and then the catheter was placed into the collecting system without prior dilatation. Technical success was achieved in all patients. There were no major procedure-related complications. There was no perirenal hematoma on control ultrasound examinations and no hematuria was observed after the procedure. The median drainage time was 75days (range: 42-120days). Two children had urinary tract infection, which was controlled by using antibiotics. The trocar nephrostomy is a practical and feasible method, which can be used for neonates with grade III-IV hydronephrosis. Copyright © 2016 Éditions françaises de radiologie.

2016-10-01

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.

Since bladder injury has no specific clinical symptoms, accurate diagnosis at first consultation is relatively difficult. To elucidate the clinical characters type of injury, clinical symptoms, laboratory findings, methods of therapy and diagnosis, we reviewed 15 patients with bladder injury over a 9-year-period 1990-1998 (10 were traumatic injuries and 5 spontaneous injuries). We found no specific clinical symptom of bladder injury. Bladder injury may occur anywhere in the bladder wall, but most commonly occurred at the dome of the bladder (60.0%). Gross hematuria was not seen in 40.0% of the cases. The accuracy of diagnosis at first consultation was relatively low (46.7%) and the tendency to make a misdiagnosis as acute abdomen on digestive organs was found. Of the traumatic injuries 60% were afflicted in the drunken state, so alcohol intoxication was considered as an important enviromental factor of bladder injury. Surgical repair of injury sites was employed in 11 cases (73.3%: 7 were intraperitoneal injuries, 4 were extraperitoneal injuries), 4 cases were managed with indwelling urethral catheter. With appropriate treatment, the prognosis is excellent.

Laparoscopic orchiopexy is a safe operation. However, the bladder can be injured during creation of the transperitoneal tunnel for the cryptorchid testis. We reviewed our experience with this complication. We searched the operative notes of patients who had undergone laparoscopic orchiopexy between August 15, 2002 and October 1, 2008, and identified bladder injuries and their treatment. A total of 93 patients underwent laparoscopic orchiopexies for 101 undescended testes during the study interval, with 3 procedures resulting in bladder injuries. The 3 operations varied with regard to whether the injury was recognized intraoperatively or postoperatively, and repaired in an open or laparoscopic fashion. Bladder injury during laparoscopic orchiopexy is a rare but serious complication that can be managed by an open or laparoscopic approach. We recommend placement of a urethral catheter and syringe assisted drainage of all urine from the bladder at the beginning of the operation, careful perivesical dissection particularly in children with prior inguinal surgery, filling and emptying of the bladder during the procedure, and maintaining a high index of suspicion especially when hematuria is observed.

Ultrasound-guided urinary bladder biopsy through a urinary catheter in a bitch.

A 34.4 kg 5 yr old spayed female mixed-breed dog was presented for evaluation of a urinary bladder mass. The dog had a recent onset of hematuria and stranguria but otherwise appeared to be healthy. Abdominal ultrasound revealed a mass in the urinary bladder. The dog was sedated and a 10-French rubber catheter that had the blunt end removed was passed from the urethra to the urinary bladder. Using ultrasound guidance, ellipsoid cup biopsy forceps were advanced through the rubber catheter to the urinary bladder mass and biopsies were successfully obtained. The dog was discharged from the hospital a few hours after the procedure. Histopathology of the mass was consistent with polypoid cystitis. Follow-up surgical removal of the polyp was uneventful, and histopathology confirmed the presurgical biopsy diagnosis. Procurement of urinary bladder biopsies through a urinary catheter with ultrasound guidance was used as a minimally invasive alternative to either cystoscopy or surgery in a bitch. Use of this technique achieved a diagnosis without the need for specialized endoscopic equipment, anesthesia, or surgery.

Radiation treatment for pelvic malignancies is typically associated with radiation injury to urinary bladder that can ultimately lead to radiation cystitis (RC). The late sequelae of radiation therapy may take many years to develop and include bothersome storage symptoms such as hematuria, which may be life-threatening in severe cases of hemorrhagic cystitis. Although no definitive treatment is currently available, various interventions are used for radiation and hemorrhagic cystitis including blood transfusion, bladder irrigation, intravesical instillation of substances such as alum, silver nitrate, prostaglandins or formalin, and fulguration of intravesical bleeding sites and surgery options such as supravesical urinary diversions and cystectomy. Effects of non-surgical treatments for radiation and hemorrhagic cystitis are of modest success and studies are lacking to control the effects caused by RC. When such measures have proven ineffective, use of bladder botulinum toxin injection has been reported. New therapy, such as intravesical immunosuppression with local tacrolimus formulation is being developed for the treatment of radiation hemorrhagic cystitis. © 2013 Wiley Publishing Asia Pty Ltd.

Nephrogenic adenoma (NA) is a rare, benign disease of the urinary tract, usually as a response to chronic irritation or trauma. Its diagnosis, staging, and treatment are not well established. We report on 3 cases of nephrogenic adenoma of the urinary bladder treated in our hospital between February 2011 and December 2012 to assess our experience and clinical outcome updating and reviewing the literature concerning this issue. All patients had undergone previous open urosurgery. Two patients had kidney transplantation. Gross hematuria and microhematuria were found in 2 patients. One patient had recurrent urinary tract infection. One patient had NA associated with transitional cell carcinoma (TCC). Recurrent nephrogenic adenomas were diagnosed in 2 patients (time to disease relapse was 5 and 9 months). All nephrogenic adenomas and recurrent tumors were treated with transurethral resection. Although NA is a benign metaplastic lesion of the urothelium, its recurrence rate is relatively high, thus careful and regular follow-up is necessary. Endoscopic characteristics of NA are not specific and a definite diagnosis must be made after histological analysis of resected specimens.

Primary signet ring cell carcinoma of urinary bladder is a rare type of bladder tumor and carries a very high mortality rate. It may have a clinical presentation similar to common diseases like benign prostatic hypertrophy and the management options are extremely limited. We report a case of 58-year-old Caucasian male who presented with a 5 month history of increased frequency of urination, nocturia and weight loss without any fever or hematuria. He was found to have an increased creatinine of 2.8 mg/dl and a prostate specific antigen level of 0.18 ng/ml. His azotemia was thought to be secondary to BPH. A Foley catheter was initially placed with a plan for outpatient follow up. On removal of the catheter his problems persisted and he returned to the hospital. Diagnostic work up including abdominal ultrasonography, computed tomography scan, retrograde pyelogram, cystography and cystoscopic biopsies revealed the diagnosis of primary signet ring cell carcinoma of urinary bladder. Although cystectomy was planned, our patient passed away before this could be done.

We report our initial experience with a laparoendoscopic single-site (LESS) repair of a bladder rupture using a home-made single-port device. A 37-year-old man presented to the emergency department with complaints of voiding difficulty and gross hematuria after blunt trauma. Cystography and computed tomography revealed an intraperitoneal bladder rupture. The patient underwent LESS repair of a bladder rupture using the Alexis wound retractor, which was inserted through the umbilical incision. A home-made single-port device was made by fixing 6½ surgical gloves to the outer rim of the retractor and securing the glove finger to the end of 3 trocars with a tie. Using the flexible laparoscopic instruments and rigid instruments, LESS surgery was performed using a procedure similar to conventional laparoscopic surgery. The patient did not have any voiding problem after removal of the urethral Foley catheter on the 10th postoperative day. To our knowledge, this is the first published report of LESS repair of a traumatic bladder rupture using a home-made single-port device in the literature.

Urethral hemangiomas are rare. They vary in size from pinpoint masses to extensive honeycomb-shape deformities leading to significant hematuria. For extensive lesions, therapeutic options have included extensive surgical resection and reconstruction or multistaged neodymium:yttrium-aluminum-garnet (Nd:YAG) laser photocoagulation. We report our experience with the use of potassium titanyl phosphate (KTP/532) laser for treatment of the extensive form. A 7-year-old boy presented with a 2-week history of urethral bleeding. He had extensive hemangiomas of the genital and perineal regions. Cystourethroscopy disclosed diffusely scattered honeycomb-shape hemangiomatous malformation of the anterior urethra. KTP/532 laser energy was delivered transurethrally to the hemangiomatous areas until they blanched. The Foley catheter was removed 24 hours postoperatively, and the patient voided clear urine without difficulty. He has remained trouble-free for more than 2 years. Judicious endoscopic single-stage therapy with KTP/532 laser may obviate open surgical intervention in most cases of extensive and symptomatic urethral hemangiomas. In view of our observation and the literature, KTP/532 laser therapy should be considered the first line of treatment.

Between January and October 2006, 15 Chios sheep died in a field located near a factory in Orhangazi, Bursa, Turkey. In addition, in May 2007, 2 ewes died after aborting in the same field. Clinical signs in affected animals prior to death were anorexia, hematuria, icterus, incoordination, and ptyalism. Postmortem findings included generalized icterus; yellow, friable livers; distended gallbladders with dense, dark bile; and dark, hypertrophic kidneys with hemorrhage. Copper (Cu) concentrations were measured in multiple specimens of the following: 9 sera, 3 livers, 3 kidneys, 4 plants (including 2 artichoke leaf specimens), 3 soil samples, and 1 drinking water sample. High Cu concentrations were present in the livers, kidneys, and sera of dead sheep, as well as in the vegetation and soil samples from the field. Chronic Cu toxicosis was confirmed as the cause of death attributed primarily to the use of copper sulfate as a fungicide for fruit trees within the field. In addition, factory dust containing Cu might have been an additional factor in the toxicosis.

To establish a repeatable, simple, and effective model of rat crush injury and crush syndrome. A total of 42 female Sprague Dawley rats (2-month-old, (CS) so as to lay a foundation for further study on CS. weighing 160-180 g) were divided randomly into the control group (n=6) and experimental group (n=36). The rats of the experimental group were used to establish the crush injury and CS model in both lower limbs by self-made crush injury mould. The survival rate and hematuria rate were observed after decompression. The biochemical indexes of blood were measured at 2, 4, 8, 12, 24, and 48 hours after decompression. The samples of muscle, kidney, and heart were harvested for morphological observation. There was no treatment in the control group, and the same tests were performed. Seven rats died and 15 rats had hematuria during compression in the experimental group. Swelling of the lower limb and muscle tissue was observed in the survival rats after reperfusion. The liver function test results showed that the levels of alanine transaminase and aspartate aminotransferase in the experimental group were significantly higher than those in the control group (P < 0.05). The renal function test results showed that blood urea nitrogen level increased significantly after 2 hours of decompression in the experimental group, showing significant difference when compared with that in the control group at 12, 24, and 48 hours after decompression (P < 0.05); the creatinine level of the experimental group was higher than that of the control group at 4, 8, 12, and 24 hours, showing significant difference at 8, 12, and 24 hours (P < 0.05). The serum K+ concentration of the experimental group was higher than that of the control group at all time, showing significant difference at the other time (P < 0.05) except at 2 hours. The creatine kinase level showed an increasing tendency in the experimental group, showing significant difference when compared with the level of the control group

Schistosoma haematobium hotspots in south Nyanza, western Kenya: prevalence, distribution and co-endemicity with Schistosoma mansoni and soil-transmitted helminths

PubMed Central

2014-01-01

Background Schistosomiasis studies in western Kenya have mainly focused on the intestinal form, with evidence of urinary schistosomiasis remaining anecdotal. Detailed disease mapping has been carried out predominantly along the shores of Lake Victoria, but there is a paucity of information on intestinal and urinary schistosomiasis in inland sites. Methods This cross-sectional survey of 3,487 children aged 7–18 years from 95 schools in south Nyanza, western Kenya determined the prevalence, infection intensity, and geographical distribution of Schistosoma haematobium, evaluating its co-endemicity with Schistosoma mansoni and soil-transmitted helminths (STHs). Helminth eggs were analyzed from single urine (for S. haematobium) and stool (for S. mansoni and STHs) samples by centrifugation and Kato-Katz, respectively. Hematuria was used as a proxy indicator for S. haematobium. Schools and water bodies (ponds, water-points, streams, dams and rivers) were mapped using Geographical Information System and prevalence maps obtained using ArcView GIS Software. Results S. haematobium infections with an overall prevalence of 9.3% (95% CI = 8.4-10.2%) were mostly prevalent in Rachuonyo, 22.4% (95% CI = 19.2-25.9% and 19.7 eggs/10 ml) and Migori, 10.7% (95% CI = 9.2-12.3% and 29.5 eggs/10 ml) districts, particularly around Kayuka pond and Ongoche river respectively. Overall infections correlated with hematuria (r = 0.9, P < 0.0001) and were more likely in boys (P < 0.0001, OR = 0.624). S. mansoni infections with an overall prevalence of 13% (95% CI =11.9-14.1%) were majorly confined along the shores of Lake Victoria. STH infections were homogenously distributed with A. lumbricoides occurring in 5.4% (95% CI = 4.7-6.3%) and T. trichiura in 2.8% (95% CI = 2.3-3.4%) of the children. Although S. mansoni infections were more co-endemic with S. haematobium, only A. lumbricoides infections were positively associated with S. haematobium (P = 0

This work was designed to evaluate methods of kidney drainage used in the surgical treatment of 250 patients with staghorn and multiple nephrolithiasis (SMN). All of them underwent open surgery that was followed by drainage of the upper urinary tract in 192 patients. Internal stenting was used in 111 cases, pyelostomy in 28, nephrostomy in 47, and internal stenting with nephrostoma in 6 cases. 91 and 20 patients had a stent inserted into the upper urinary tract in a retrograde and antegrade manner respectively. Retrograde stenting was bilateral in 14 and unilateral in 66 cases. 85% of the cases with ureter stents were followed up as outpatients for 4-5 weeks and only 10% for 6-7 weeks. Forty and ten patients with stents presented with marked dysuria and hematuria respectively. On the whole, combined antibacterial treatment with drainage of the upper urinary tract significantly improved long-term results of SMN treatment. It is concluded that nephrostomy and pyelostomy should be performed on days 14-18 and 10-12 respectively whereas the stent needs to be removed between weeks 2 and 8 after surgery.

IgM nephropathy; can we still ignore it

2013-01-01

Context:IgM nephropathy (IgMN) is a relatively less recognized clinico-immunopathological entity in the domain of glomerulonephritis , often thought to be a bridge between minimal change disease and focal segmental glomerulosclerosis. Evidence Acquisitions: Directory of Open Access Journals (DOAJ), Google Scholar, Pubmed (NLM), LISTA (EBSCO) and Web of Science has been searched. Results: IgM nephropathy can present as nephritic syndrome or less commonly with subnephrotic proteinuria or rarely hematuria. About 30% patients respond to steroids whereas others are steroid dependent / resistant. They should be given a trial of Rituximab or stem cell therapy. Conclusions:IgM nephropathy (IgMN) is an important and rather neglected pathology responsible for renal morbidity in children and adults in developing countries as compared to developed nations with incidence of 2-18.5% of native biopsies. Abnormal T-cell function with hyperfunctioning suppressor T-cells are believed to be responsible for this disease entity. Approximately one third of the patients are steroid responders where as the remaining two thirds are steroid resistant or dependent. Therapeutic trials including cell therapies targeting suppressor T-cells are required. PMID:24475434

There continues to be disagreement related to the appropriate therapeutic regimen to be used when the donor and the recipient in kidney transplant operations are identical twins. Here we present two cases of kidney transplantation between identical twins. Both recipients had end-stage renal disease (ESRD) caused by primary nephropathy. We also present information gleaned from a literature review of similar cases. The first recipient was a 26-year-old man who experienced biopsy-proven IgA nephropathy 10 months post-transplantation. Mycophenolate mofetil (MMF), angiotensin receptor blockers (ARBs), and steroids were used to reverse this pathologic condition. Till now, 76 months post-transplantation, the patient is stable, and the new kidney is functioning well. The second recipient was a 20-year-old woman who had hematuria and proteinuria 3 months post-transplantation, and crescent glomerulonephritis with mild to moderate interstitial injury was proven by biopsy 11 months postoperatively. This patient did not respond to various treatments and resumed hemodialysis 15 months post-transplantation. These case studies show that immunosuppressive therapy should be maintained in kidney transplant recipients who are identical twins with ESRD caused by initial nephropathy.

2014-09-01

Metachronous adrenal metastasis from contralateral renal cell carcinoma (RCC) surgery is an extremely rare condition. Iatrogenic Addison's disease occurring after metastasectomy (adrenalectomy) is an even rarer clinical entity. We present a case of a 68-year-old male with hematuria and left flank pain 9 years prior. The patient underwent left transperitoneal radical nephrectomy involving the ipsilateral adrenal glands due to a centrally-located, 75-mm in diameter solid mass lesion in the upper pole of the left kidney. The tumour lesion was confined within the renal capsule, and the histo-pathological examination revealed a Fuhrman nuclear grade II clear cell carcinoma. The patient underwent transperitoneal right adrenalectomy. The histopathological examination revealed metastasis of clear cell carcinoma. The patient was diagnosed with iatrogenic Addison's disease based on the measurement of serum cortisol levels and the adrenocorticotropic hormone (ACTH) stimulation test, after which glucocorticoid and mineralocorticoid replacement was initiated. The patient did not have local recurrence or new metastasis in the first year of the follow-up. The decision to perform ipsilateral adrenalectomy during radical nephrectomy constitutes a challenge, and the operating surgeon must consider all these rare factors.

Lead intoxication is a worldwide health problem which frequently affects the kidney. In this work, we studied the effects of chronic lead intoxication (500 ppm of Pb in drinking water during seven months) on the structure, function and biochemical properties of rat proximal tubule cells. Lead-exposed animals showed increased lead concentration in kidney, reduction of calcium and amino acids uptake, oxidative damage and glucosuria, proteinuria, hematuria and reduced urinary pH. These biochemical and physiological alterations were related to striking morphological modifications in the structure of tubule epithelial cells and in the morphology of their mitochondria, nuclei, lysosomes, basal and apical membranes. Interestingly, in addition to the nuclei, inclusion bodies were found in the cytoplasm and in mitochondria. The epithelial cell structure modifications included an early loss of the apical microvillae, followed by a decrement of the luminal space and the respective apposition and proximity of apical membranes, resulting in the formation of atypical intercellular contacts and adhesion structures. Similar but less marked alterations were observed in subacute lead intoxication as well. Our work contributes in the understanding of the physiopathology of lead intoxication on the structure of renal tubular epithelial cell-cell contacts in vivo.

Alport syndrome is an inherited progressive nephropathy arising from mutations in the type IV collagen genes, COL4A3, COL4A4, and COL4A5. Symptoms also include sensorineural hearing loss and ocular lesions. We determined the molecular basis of Alport syndrome in a non-consanguineous Ashkenazi Jewish family with multiple affected females using linkage analysis and next generation sequencing. We identified a homozygous COL4A3 mutation, c.40_63del, in affected individuals with mutant alleles inherited from each parent on partially conserved haplotypes. Large-scale population screening of 2017 unrelated Ashkenazi Jewish samples revealed a carrier frequency of 1 in 183 indicating that COL4A3 c.40_63del is a founder mutation which may be a common cause of Alport syndrome in this population. Additionally, we determined that heterozygous mutation carriers in this family do not meet criteria for a diagnosis of Thin Basement Membrane Nephropathy and concluded that carriers of c.40_63del are not likely to develop benign familial hematuria. © 2013 John Wiley & Sons A/S.

Xanthogranulomatous cystitis (XC) is a very rare chronic benign inflammatory disease of the bladder. It may cause local invasion although it is not a malign lesion and may occur together with malign lesions. It has a clinical importance as the distinction from malign lesions is difficult clinically and pathologically. Sharing a 37-year-old female case with giant XC imitating bladder tumor referring to the hospital with hematuria and stomach ache, together with current literature, we wanted to present that the disease can be treated with bladder-preserving approaches instead of radical approaches even though the mass is big in these cases. Application of basic excision and partial resection for small masses and radical cystectomy for large masses was reported in literature. We think that our case may provide a contribution to literature in treatment approach since we provided surgical cure with partial resection in a big mass with dimensions of 9 cm × 8 cm which is different from the present literature. Even though XC is a rare disease, it should be considered in prediagnosis for especially big dimensioned masses, and treatment should be planned according to the pathology result after together with cystoscopy in suitable patients.

Objectives To analyze the efficacy of intrarectal ice application as an anesthetic method prior to transrectal ultrasound (TRUS) guided prostate biopsy. Materials and Methods A total of 120 consecutive men were included into the study prospectively. Patients were equally randomized as group 1 and 2 with 60 patients each. Ice was applied as an anesthetic method 5 minutes before procedure to the patients in group 1. Patients in group 2 were applied 10 ml of 2% lidocaine gel 10 minutes before procedure. Twelve core biopsy procedure was performed for all patients. The pain level was evaluated using a visual analogue scale (VAS). Results Median pain score was 3.5 (1-8) in group 1 and 5 (1-8) in group 2. There is significantly difference between groups regarding the mean sense of pain level during the procedure. (p=0.007) There was also no difference in complications between two groups about presence and duration of macroscopic hematuria and rectal bleeding. Conclusions Intrarectal ice application prior to TRUS prostate biopsy has an effect on reducing pain. Development of new techniques about cold effect or ice can make this method more useful and decrease complication rates. PMID:25928515

We report a rare case of a collision between a gastric cancer and a malignant lymphoma with a wide systemic metastasis, combined with esophagus cancer, stomach cancer and malignant lymphoma. A 73-year-old man complained of gross hematuria and swelling of the right testis. Magnetic resonance imaging (MRI) revealed that both testes were swollen with unequal contrast and there were numerous tumors in the retroperitoneal space and pelvis. He was diagnosed with malignant diffuse large B cell lymphoma by immunostaining from the extirpated right testis. He received six cycles of R-CHOP therapy. After the second cycle, partial remission was recognized, but the tumors spread again by the fourth cycle. Thereafter, we performed MTX-HOPE therapy as a salvage therapy for four cycles. During this chemotherapy, he felt epigastralgia; esophagus cancer (squamous cell carcinoma) and stomach cancer (highly-differentiated adenocarcinoma) were found by upper endoscopy. However, the gastrointestinal cancer was inoperable, since the malignant lymphoma was progressive. His general status had been exacerbated, and he died about one year after he was diagnosed with malignant lymphoma. Pathological examination revealed that the adenocarcinoma had partly collided with the malignant lymphoma.

1998-05-01

To report a possible case of leukocytoclastic vasculitis associated with clarithromycin therapy. An 83-year-old white woman was prescribed clarithromycin for pneumonia. Six days after her initial presentation, she developed lesions on her palms. Clarithromycin was discontinued at that time. The following day she developed purpuric eccymotic nonblanching lesions that primarily appeared on the lower extremities, buttocks, and abdomen. Colonoscopy revealed generalized erythema and edema of the bowel mucosa. Gastroscopy revealed duodenitis and gastritis, but no bleeding or ulceration. Skin biopsy of the lesions was compatible with leukocytoclastic vasculitis. Renal function was not affected, although hematuria was noted. All symptoms resolved after drug withdrawal and a short course of corticosteroids. Searches were performed on MEDLINE, Embase, International Pharmaceutical Abstracts, and major adverse drug reaction databases to identify reports and articles discussing clarithromycin- and macrolide-induced leukocytoclastic vasculitis. Leukocytoclastic vasculitis is one category of drug hypersensitivity reactions characterized by distinctive patterns of perivascular inflammation. The case described here is consistent with the diagnosis of leukocytoclastic vasculitis, and is similar to the other single published case report associated with clarithromycin. Leukocytoclastic vasculitis induced by clarithromycin is a rare but serious potential adverse effect.

2015-11-01

Abdominal pain is one of the most common complaints in the pediatric ED. Because of the broad range of potential diagnoses, it can pose challenges in diagnosis and therapy in the preadolescent girl. An 11-year-old previously healthy girl presented to our pediatric ED with fever, decreased appetite, vaginal bleeding, and abdominal pain. Initial evaluation yielded elevated creatinine levels, leukocytosis with bandemia, elevated inflammatory markers, and urine concerning for a urinary tract infection. She began receiving antibiotics for presumed pyelonephritis and was admitted to the hospital. After worsening respiratory status and continued abdominal pain, a computed tomography scan was obtained and a pelvic foreign body and abscess were identified. Adolescent gynecology was consulted for examination under anesthesia for abscess drainage and foreign body removal. A foreign body in the vagina or uterus can present as vaginal discharge, vaginal bleeding, abdominal pain, dysuria, or hematuria. Because symptoms can be diverse, an intravaginal or uterine foreign body should be considered in the preteen female patient presenting to the ED with abdominal pain.

2013-08-01

Nephrolithiasis has been reported in 20-28% of patients, of whom 50% are symptomatic for stone disease and 20% require definite urologic intervention. The management of nephrolithiasis includes oral alkali dissolution therapy, extracorporeal shock wave lithotripsy and surgical treatment. In such patients, percutaneous nephrolithotomy (PNL) as a method of stone treatment has been reported in few cases with limited experience. The aim of this study is to present our experience of PNL in autosomal dominant polycystic kidney disease (ADPKD) and assessing the outcome results. From 2002 to 2011, 22 patients (26 renal units) suffering from ADPKD with stone were managed by PNL. Demographic characteristics, operative parameters and postoperative complications were recorded and analysed. The overall success rate of PNL was 82.1% and PNL with extracorporeal shock wave lithotripsy for clinically significant residual fragments was 92.85% respectively. The hematuria required blood transfusion (n = 9), postoperative fever due to cyst infection (n = 4) and paralytic ileus (n = 3) were recorded. The PNL in ADPKD PNL is safe and effective but have more postoperative complications such as bleeding requiring transfusions, fever due to cyst infection and paralytic ileus.

The study aimed to evaluate the effect of exercise on urine sediment in adolescent soccer players. In 25 15-year-old (range 14.4-15.8 yrs) athletes, urinary protein, osmolality and cytology were analyzed by flow cytometry and automated dipstick analysis before (T(0)), during (T(1)), and after a match (T(2)). All athletes had normal urine analysis and blood pressure at rest, tested before the start of the soccer season. Fifty-eight samples were collected (T(0): 20, T(1): 17, T(2): 21). Proteinuria was present in 20 of 38 samples collected after exercise. Proteinuria was associated with increased urinary osmolality (p < .001) and specific gravity (p < .001). Hyaline and granular casts were present in respectively 8 of 38 and 8 of 38 of the urinary samples after exercise. The presence of casts was associated with urine protein concentration, osmolality, and specific gravity. This was also the case for hematuria (25 of 38) and leucocyturia (9 of 38).

To establish a web-based quantitative signal detection system for adverse drug reactions (ADRs) based on spontaneous reporting to the Guangdong province drug-monitoring database in China. Using Microsoft Visual Basic and Active Server Pages programming languages and SQL Server 2000, a web-based system with three software modules was programmed to perform data preparation and association detection, and to generate reports. Information component (IC), the internationally recognized measure of disproportionality for quantitative signal detection, was integrated into the system, and its capacity for signal detection was tested with ADR reports collected from 1 January 2002 to 30 June 2007 in Guangdong. A total of 2,496 associations including known signals were mined from the test database. Signals (e.g., cefradine-induced hematuria) were found early by using the IC analysis. In addition, 291 drug-ADR associations were alerted for the first time in the second quarter of 2007. The system can be used for the detection of significant associations from the Guangdong drug-monitoring database and could be an extremely useful adjunct to the expert assessment of very large numbers of spontaneously reported ADRs for the first time in China.

Renal carcinomas associated with Xp11.2 translocations/TFE3 gene fusions are rare subtypes of renal neoplasm that predominantly occur in younger individuals. There are very few reports describing the cytologic features of these tumors. A 27-year-old man presented with hematuria and was found to have a mass in the lower part of the right kidney. Cytology of catheterized urine obtained from the right renal pelvis showed clusters of cells with abundant clear or eosinophilic granular cytoplasm, large round nuclei and prominent nucleoli. Papillary clusters containing thin fibrous stroma were occasionally seen. Voided urine cytology showed similar cell clusters but degeneration made the features obscure. Nephroureterectomy revealed a renal tumor showing a mixed papillary and nested architecture. The diagnosis was confirmed by immunohistochemistry and fluorescence in situ hybridization. The present case indicates that the characteristic features of these tumor subtypes can be retained in urine cytology. Cytology may be enough to suspect these tumors as part of the differential diagnosis when the patient's age and imaging findings are taken into account and may facilitate further studies for a definitive diagnosis. © 2014 S.

Here we describe the case of a 19-year-old woman, in her 29th week of gestation, who was from Llumpe (Ancash, Peru) and had a history of traveling to Chanchamayo (Junín, Peru) and Rinconada (Ancash, Peru). The patient presented at Chacas Hospital (Chacas, Ancash, Peru) with general malaise, dehydration, respiratory distress, jaundice, the sensation of thermal rise, and abdominal pain. Analysis of blood smears revealed 60% hemoparasites. She was transferred to Ramos Guardia Hospital (Huaraz, Peru) where she presented increasing respiratory distress, choluria, hematuria, and decreased urine output, moreover she was positive for Plasmodium. From there she was transferred to Cayetano Heredia Hospital (Lima, Peru), where she was admitted to the intensive care unit (ICU) with multiple organ failure, stillbirth, and leading to death. She underwent mechanical ventilation, was administered clindamycin, and was prescribed quinine, which she did not received due a lack by availability. The evolution of the illness was torpid, and she ultimately developed multiple organ failure and died. Plasmodium vivax infection was confirmed. Accordingly, we emphasize the importance of improving our diagnostic capabilities and management techniques to enable clinicians to provide adequate and timely treatment.

Small cell carcinoma of the urinary bladder is an infrequent lesion. We present the case of a 68-year-old male who arrived at the emergency room with a history of 24-h gross hematuria. Imaging studies show a urinary bladder tumor with a 218 cc volume that during a 20-day period increased to 426 cc. Histopathological images with hematoxylin-eosin show an infiltrating solid mass with uneven borders. It is composed of neoplastic cells with evident nuclei predominance and scant cytoplasm (small cells). Chromogranin immunohistochemical staining shows a diffusely positive cytoplasmic granular pattern on neoplastic cells. High molecular weight cytokeratin staining shows a negative pattern on neoplastic cells along with a positive pattern on reporsurrounding normal urothelium. Tumoral mass is positive for synaptophysin and CD-56 and negative for CK-7 and CK-20. Patient therapy was based on radiation plus chemotherapy. Small cell carcinoma of the urinary bladder represents 0.35-0.70% of urinary bladder tumors. Histological and immunohistochemical identification are key elements in the diagnosis. Treatment approach is based on cisplatin-based chemotherapy plus radical cystectomy, except when metastatic disease is present.

A new compact male intermittent catheter was compared with a regular intermittent male catheter in terms of safety and acceptability. In this randomized, single-blind, cross-over study, healthy male volunteers were catheterized twice with a compact catheter and twice with a regular catheter. 28 participants were enrolled. Mean ± SD discomfort (visual analogue scale; primary objective) was 2.25 ± 1.5 and 2.52 ± 1.8 for the compact and regular catheters, respectively (difference -0.27; 95% confidence interval -0.73 to 0.19); there was no significant difference in hematuria (p = 0.54) or discomfort/stinging/pain at first micturition (p = 0.56). During insertion, handling was easier (p = 0.0001) and touching the coating was necessary less often (2.2 vs. 81.3% of catheterizations; p < 0.0001) with the compact catheter; it was preferred by nurses for 20 of 23 participants. No adverse events were reported. Short-term safety of the new compact catheter was at least as good as that of the regular male intermittent catheter and handling was improved. Copyright © 2011 S.

Anomalies of the fetal urachus are rare. Normally, the postnatal urachus presents as a fibrous band extending from the bladder to the umbilicus. Urachal cysts may occur in postnatal life. Spontaneous perforation of urachal cysts is a very rare condition, which clinically may not be distinguishable from other acute abdominal conditions. We report a case of a 63-year-old male with a history of recurrent urinary tract infections and a bladder rupture caused by a spontaneous perforation of an infected urachal cyst. The symptomatology showed abdominal rigidity and pain, a palpable mass in the lower abdomen, and hematuria. Laboratory findings showed leukocytosis and an increased CRP level. The bladder rupture was confirmed by cystography. Bacteriologic examination identified Proteus vulgaris, Corynebacterium species, and Klebsiella pneumoniae. Most of the published cases in the literature report about intraperitoneal perforation of infected urachal cysts. In the present case, we found a spontaneous perforation of an infected urachal cyst leading to an extraperitoneal bladder rupture with an extraperitoneal limitation of the infection. The definitive therapy was complete surgical excision including a cuff of the bladder, drainage, and systemic broad-spectrum and local application of antibiotics. The further course was uneventful.

A report on a patient who sustained a burn and perforation of the urinary bladder from visible sparks emanating from a unipolar coagulating device during the couse of laparoscopic sterilization is presented. It is the first report of urinary bladder burns using a unipolar coagulating device. A 24-year-old woman, gravida 10, para 3, abortus 7, underwent a laparoscopic sterilization with a unipolar coagulating device. As the physician was finishing the coagulation, a spark from the device caused a 1-2 cm burn with a central area of perforation into the urinary bladder. Conservative treatment was recommended, and consisted of Foley catheterization and drainage for 5 days. Initial urine culture revealed Klebsiella species, and oral ampicillin was prescribed. Hematuria was noted throughout the patient's hospitalization, and blood clots were present in the urine on Day 2 postoperation. The patient had no abdominal or flank pain, was afebrile, and had a stable hemoglobin level during the hospital stay. Cystography was performed on Day 5 postoperatively and demonstrated no perforation. Foley catheter was removed. Patient was discharged 2 days later and remains in good health 3 months postoperatively.

Laparoscopic hernia repair and bladder injury.

Bladder injury is a complication of laparoscopic surgery with a reported incidence in the general surgery literature of 0.5% and in the gynecology literature of 2%. We describe how to recognize and treat the injury and how to avoid the problem. We report two cases of bladder injury repaired with a General Surgical Interventions (GSI) trocar and a balloon device used for laparoscopic extraperitoneal inguinal hernia repair. One patient had a prior appendectomy; the other had a prior midline incision from a suprapubic prostatectomy. We repaired the bladder injury, and the patients made a good recovery. When using the obturator and balloon device, it is important to stay anterior to the preperitoneal space and bladder. Prior lower abdominal surgery can be considered a relative contraindication to extraperitoneal laparoscopic hernia repair. Signs of gas in the Foley bag or hematuria should alert the surgeon to a bladder injury. A one- or two-layer repair of the bladder injury can be performed either laparoscopically or openly and is recommended for a visible injury. Mesh repair of the hernia can be completed provided no evidence exists of urinary tract infection. A Foley catheter is placed until healing occurs.

To present complications and pitfalls in voiding cystourethrography (VCUG) and introduce a guideline for performing VCUG in a long-term spinal cord injury (SCI) patient with neurogenic bladder dysfunction (NBD) and contracted bladder. A case report. Maharaj Nakorn Chiang Mai Hospital, Chiang Mai, Thailand. We describe a chronic C(5) tetraplegic man with NBD and contracted bladder, who developed autonomic dysreflexia (AD), gross hematuria and extravasation of contrast median during VCUG. A foley catheter was retained after VCUG. AD was resolved and urine cleared after a week of continuous bladder irrigation. VCUG should be performed with caution in a long-term SCI patient with NBD and contracted bladder. Forceful pushing of the contrast media by the hand-injection method caused abrupt distention of the contracted bladder, damaged bladder mucosa and aggrevated AD. We suggest a guideline as follows: report bladder capacity and AD, if present, in an X-ray requisition form; use the gravity-drip method, stop the drip and drain the contrast media if a sudden headache and rising of blood pressure (BP) develop; observe urine colour, and report if bleeding or AD occurs.

Primary small cell carcinoma of the urinary bladder is very rare; only several studies have been reported in the English literature. A 62-year-old woman was admitted to our hospital because of hematuria and dysuria. Bladder endoscopy revealed a large polypoid tumor at the bladder base. Transurethral bladder tumorectomy (TUR-BT) was performed. Many TUR-BT specimens were obtained. Histologically, the bladder tumor was pure small cell carcinoma. Immunohistochemically, the tumor cells were positive for cytokeratin (CK) AE1/3, CK CAM5.2, CK8, CK18, neurone-specific enolase, chromogranin, NCAM (CD56), synaptophysin, Ki-67 (labeling=100%), p53, KIT (CD117), and platelet-derived growth factor receptor-α (PDGFRA). The tumor cells were negative for CK5/6, CK 34BE12, CK7, CK14, CK19, CK20, p63, CD45, and TTF-1. A molecular genetic analysis using PCR-direct sequencing showed no mutations of KIT (exons 9, 11, 13 and 17) and PDGFRA (exons 12 and 18) genes. No metastases were found by various imaging techniques. The patient is now treated by cisplatin-based chemotherapy.

We sought to assess the early success and safety of catheter-directed, ultrasound-assisted (CDUA) thrombolysis for acute pulmonary embolism (PE) in patients deemed to be "high risk" for thrombolytic therapy. A retrospective evaluation of patients who underwent CDUA pulmonary thrombolysis in our practice during 39 months is reported. There were 91 patients considered, all of whom presented with acute PE as diagnosed by computed tomography angiography. The ratio of the right ventricle to left ventricle diameter (RV axial :LV axial ) was noted, as were preprocedure pulmonary artery pressures (PAPs). Demographic data, significant medical history, and procedure details were recorded. Standard thrombolysis protocol was followed (1 mg of tissue plasminogen activator per hour per catheter after an initial 2-mg bolus per catheter). Minitab 17 (Minitab Inc, State College, PA) was used for data analysis. There were 91 patients who had a computed tomography diagnosis of acute PE and pulmonary hypertension (PAP >25 mm Hg). Seventeen patients (19%) were deemed to be at high risk for bleeding, predicted by recent hemorrhage, major surgery within 3 weeks, acute myocardial infarction, and cardiac arrest with cardiopulmonary resuscitation within 1 week. The high-risk patients in our study were noted to have higher RV:LV ratios and lower oxygen saturations on admission (P < .05). On computed tomography angiography, the mean pretherapy RV axial :LV axial ratio was 1.5 ± 0.4. The mean pretherapy PAP was 56.2 ± 15.2 mm Hg. After 18.5 ± 3.5 hours of thrombolysis, the mean post-therapy PAP was 34.3 ± 10.4 mm Hg, with a pressure drop of 21.9 ± 4.8 mm Hg (39% decrease; P < .001). In total, seven patients (8%) suffered bleeding complications that required intervention-four gastrointestinal bleeds, a rectus sheath hematoma, and one gross hematuria. Three of the seven complications occurred in the high-risk group (3/17) and the other four in the general population of patients (4

Various time points within a trajectory were indexed, randomly sampled, and followed for 2 years to estimate portion of progressors (>5 mL/min/1.73 m2 /y decline), stable state (0-2 mL/min/1.73 m2 /y decline), and regressors (>2 mL/min/1.73 m2 /y incline). In this retrospective observational cohort study, participants were identified through a chronic renal disease registry in British Columbia, Canada, from 1995 to 2012. Inclusion criteria were biopsy proven or hematuria with a family history of Alport syndrome. Individual patients and family group members were studied. Trajectory of renal decline described graphically by fitting a cubic smoothing spline to patient's serial estimated glomerular filtration rate (eGFR) measures.

Nuclear factor (NF)-κB regulates several genes implicated in the inflammatory response and represents an interesting therapeutic target. We examined the effects of gliotoxin (a fungal metabolite) and parthenolide (a plant extract), which possess anti-inflammatory activities in vitro, on the progression of experimental glomerulonephritis. In the anti-Thy 1.1 rat model, gliotoxin (75 μg/rat/day, 10 days, n = 18 rats) markedly reduced proteinuria, glomerular lesions, and monocyte infiltration. In anti-mesangial cell nephritis in mice, parthenolide (70 μg/mouse/day, 7 days, n = 17 mice) significantly decreased proteinuria, hematuria, and glomerular proliferation. NF-κB activity, localized in glomerular and tubular cells, was attenuated by either gliotoxin or parthenolide, in association with diminished renal expression of monocyte chemoattractant protein-1 and inducible nitric oxide synthase. In cultured mesangial cells and monocytes, gliotoxin and parthenolide inhibited NF-κB activation and expression of inflammatory genes induced by lipopolysaccharide and cytokines, by blocking the phosphorylation/degradation of the IκBα subunit. In summary, gliotoxin and parthenolide prevent proteinuria and renal lesions by inhibiting NF-κB activation and expression of regulated genes. This may represent a novel approach for the treatment of immune and inflammatory renal diseases. PMID:12368222

Renal and urologic problems in pediatric condition falsification (PCF)/Munchausen by proxy (MBP) can pose frustrating diagnostic and management problems. Five previously unreported victims of PCF/MBP are described. Symptoms included artifactual hematuria, recalcitrant urinary infections, dysfunctional voiding, perineal irritation, glucosuria, and "nutcracker syndrome", in addition to alleged sexual abuse. Falsifications included false or exaggerated history, specimen contamination, and induced illness. Caretakers also intentionally withheld appropriately prescribed treatment. Children underwent invasive diagnostic and surgical procedures because of the falsifications. They developed iatrogenic complications as well as behavioral problems stemming from their abuse. A PCF/MBP database was started in 1995 and includes the characteristics of 135 PCF/MBP victims examined by the first author between 1974 and 2006. Analysis of the database revealed that 25% of the children had renal or urologic issues. They were the presenting/primary issue for five. Diagnosis of PCF/MBP was delayed an average of 4.5 years from symptom onset. Almost all patients were victimized by their mothers, and maternal health falsification and somatization were common. Thirty-one of 34 children had siblings who were also victimized, six of whom died. In conclusion, falsifications of childhood renal and urologic illness are relatively uncommon; however, the deceits are prolonged and tortuous. Early recognition and intervention might limit the harm.

To evaluate the safety and efficacy of transarterial nephrectomy, i.e., complete renal artery embolization, as an alternative to surgical nephrectomy. This retrospective study included 11 patients who underwent transarterial nephrectomy due to a high risk of surgical nephrectomy or their refusal to undergo surgery during the period from April 2002 to February 2013. Medical records and radiographic images were reviewed retrospectively to collect information regarding underlying etiologies, clinical presentations and embolization outcomes. The underlying etiologies for transarterial nephrectomy included recurrent hematuria (chronic transplant rejection [n = 3], arteriovenous malformation or fistula [n = 3], angiomyolipoma [n = 1], or end-stage renal disease [n = 1]), inoperable renal or ureteral injury (n = 2), and ectopic kidney with urinary incontinence (n = 1). The technical success rate was 100%, while clinical success was achieved in eight patients (72.7%). Subsequent surgical nephrectomy was required for three patients due to an incomplete nephrectomy effect (n = 2) or necrotic pyelonephritis (n = 1). Procedure-related complications were post-infarction syndrome in one patient and necrotic pyelonephritis in another patient. Of four patients with follow-up CT, four showed renal atrophy and two showed partial renal enhancement. No patient developed a procedure-related hypertension. Transarterial nephrectomy may be a safe and effective alternative to surgical nephrectomy in patients with high operative risks.

To evaluate the frequency and the nature of genital trauma in female children in Jordan, and to stress the role of forensics. This is a cross-sectional study conducted between March 2008 and December 2011 in Jordan University Hospital, Amman, Jordan. Sixty-three female children were examined for genital trauma after immediate admission. The mechanism of injury was categorized and reported by the examiners as either straddle, non-straddle blunt, or penetrating. Straddle injury was the cause of injuries in 90.5% of patients, and contusions were the significant type of injury in 34% of patients, followed by abrasions in both labia majora and labia minora. Only one case suffered from non-intact hymen and 2 had hematuria. These 3 cases (4.7%) required surgical intervention and follow-up after 2 weeks. Straddle injuries were the main cause of genital trauma and rarely affect the hymen; however, due to the sensitivity of the subject and the severity of the traumas, forensic physicians should provide consultation and cooperate with gynecologists to exclude or confirm hymenal injuries, where empathy is necessary to mitigate tension associated with such injuries for the sake of the child and the parents as well, along with good management of the injury type.

From December 1985 to December 1989, 100 consecutive simultaneous pancreas-kidney (SPK) transplants were performed at the University of Wisconsin Hospital and Clinics. Bladder drainage technique was used for all grafts. One- and three-year patient survival was 93% and 90%; kidney survival, 90% and 85%; and pancreas survival, 86% and 84%. Quadruple immunosuppressive therapy was used in all patients and consisted of either MALG or OKT3 induction, and cyclosporine, prednisone, and azathioprine maintenance therapy. OKT3 induction therapy was used in 42 patients and Minnesota antilymphocyte globule in 58 patients, with equivalent results except for more opportunistic infection with OKT3. The duodenal button technique was used in the first 17 patients with systemic anticoagulation and was associated with significantly more postoperative bleeding and infection compared with the duodenal segment technique. The most common surgical complication of the duodenal segment technique was urine leak (13%), which usually occurred from the distal duodenal segment. The most common urologic complication of bladder drainage was hematuria (13%), which was usually self-limited. Within 6 months of transplantation, 84% of patients developed urinary tract infections, and 25% of patients had opportunistic infections. The surgical techniques and immunosuppressive methods used in this series are reviewed, and strategies for preventing medical and surgical complications are outlined. PMID:1741650

Urethral calculus is a rare form of urolithiasis with an incidence lower than 0.3%. We determined the outcomes of 15 patients with urethral stone, of which 8 were pediatric, including an undiagnosed primary fossa navicularis calculus. Fifteen consecutive male patients, of whom eight were children, with urethral calculi were assessed between 2000 and 2005 with a mean of 19 months' follow-up. All stones were fusiform in shape and solitary. Acute urinary retention, interrupted or weak stream, pain (penile, urethral, perineal) and gross hematuria were the main presenting symptoms in 7 (46.7%), 4 (26.7%), 3 (20%) and 1 (6.6%) patient, respectively. Six of them had accompanying urethral pathologies such as stenosis (primary or with hypospadias) and diverticulum. Two patients were associated with upper urinary tract calculi but none of them secondary to bladder calculi. A 50-year-old patient with a primary urethral stone disease had urethral meatal stenosis accompanied by lifelong lower urinary tract symptoms. Unlike the past reports, urethral stones secondary to bladder calculi were decreasing, especially in the pediatric population. However, the pediatric patients in their first decade are still under risk secondary to the upper urinary tract calculi or the primary ones.

Basics of kidney biopsy: A nephrologist's perspective

PubMed Central

Agarwal, S. K.; Sethi, S.; Dinda, A. K.

2013-01-01

The introduction of the kidney biopsy is one of the major events in the history of nephrology. Primary indications of kidney biopsy are glomerular hematuria/proteinuria with or without renal dysfunction and unexplained renal failure. Kidney biopsy is usually performed in prone position but in certain situations, supine and lateral positions may be required. Biopsy needles have changed with times from Vim–Silverman needle to Tru-cut needle to spring-loaded automatic gun. The procedure has also changed from blind bedside kidney biopsy to ultrasound marking to real-time ultrasound guidance to rarely computerized tomography guidance and laparoscopic and open biopsy. In very specific situations, transjugular kidney biopsy may be required. Most of the centers do kidney biopsy on short 1-day admission, whereas some take it as an outdoor procedure. For critical interpretation of kidney biopsy, adequate sample and clinical information are mandatory. Tissue needs to be stained with multiple stains for delineation of various components of kidney tissue. Many consider that electron microscopy (EM) is a must for all kidney biopsies, but facilities for EM are limited even in big centers. Sophisticated tests such as immunohistochemistry and in-situ hybridization are useful adjuncts for definitive diagnosis in certain situations. PMID:23960337

Diagnostic examination of the child with urolithiasis or nephrocalcinosis.

PubMed

Hoppe, Bernd; Kemper, Markus J

2010-03-01

Urolithiasis and nephrocalcinosis are more frequent in children then currently anticipated, but still remain under- or misdiagnosed in a significant proportion of patients, since symptoms and signs may be subtle or misleading. All children with colicky abdominal pain or macroscopic hematuria should be examined thoroughly for urolithiasis. Also, other, more general, abdominal manifestations can be the first symptoms of renal stones. The patients and their family histories, as well as physical examination, are important initial steps for diagnostic evaluation. Thereafter, diagnostic imaging should be aimed at the location of calculi but also at identification of urinary tract anomalies or acute obstruction due to stone disease. This can often be accomplished by ultrasound examination alone, but sometimes radiological methods such as plain abdominal films or more sensitive non-enhanced computed tomography are necessary. Since metabolic causes are frequent in children, diagnostic evaluation should be meticulous so that metabolic disorders that cause recurrent urolithiasis or even renal failure, such as the primary hyperoxalurias and others, can be ruled out. The stone is not the disease itself; it is only one serious sign! Therefore, thorough and early diagnostic examination is mandatory for every infant and child with the first stone event, or with nephrocalcinosis.

A 46-year-old man was admitted to our clinic because of acute heart failure. Six years before admission he was pointed out cardiomegary and hematuria. One year later, he was diagnosed as having jugular foramen syndrome. On admission, he had a fever and dyspnea. Pansystolic blowing murmur was audible at the apex. The chest ratio on his chest X-ray was 52.5%. An electrocardiogram showed left ventricular hypertrophy. An echocardiogram showed marked dilatation and severe dysfunction of left ventricle. Radionuclide scanning with technetium 99 m pyrophosphate identified inflammatory change in the apex. Myocardial biopsy showed fibrotic degeneration and IgG deposits in myocardium. Blood examination showed anemia, lymphopenia. positive anti-nuclear antibody (1000 times, shaggy pattern), positive anti ds-DNA antibody and hypocomplementemia. Furthermore, proteinuria was pointed out. Renal biopsy showed focal segmental glomerulonephritis with active necrotizing lesion (type III nephritis). Lupus myocarditis and nephritis was diagnosed. After prednisolone (80 mg/day) was administered. left ventricular function and hypocomplementemia improved. The ACE inhibitor was also used for proteinuria. In spite of a little amount of blood transfusion, he showed hepatic hemosiderosis. We suspect that the cause of hemosiderosis was related chronic inflammation of active lupus. It was treated with Erythropoietin.

Epstein-Barr virus (EBV) infection can cause diverse renal manifestations ranging from microscopic hematuria to acute renal failure. Membranous nephropathy (MN) is an uncommon and usually secondary cause of nephrotic syndrome in children, and has been reported after chronic infections and antigenemia. We report two pediatric cases of secondary MN associated with acute and chronic systemic EBV infection. Patient 1 had a liver transplant for cirrhosis due to biliary atresia and developed chronic EB viremia. Membranous nephropathy occurred 3 years later and with aggressive therapy has partially subsided, in temporal association with a drop in blood EBV PCR levels. The other patient had a primary immunodeficiency and developed a lymphoproliferative disorder attributed to EBV. Nephrotic syndrome developed at initial presentation and was associated with MN on biopsy. The patient cleared the virus from blood, which was associated with eventual resolution of the MN. We postulate that EB viremia in patients lacking a fully competent immune system, but without a renal allograft, may create a susceptible environment for chronic systemic EB antigenemia that can then lead to immune-complex MN in the kidney. The association of EBV with renal histological changes consistent with MN has been suggested but not directly described before.

BK virus (BKV)-associated hemorrhagic cystitis (HC), varying from mild hematuria with or without dysuria to life-threating bleeding and clots that may cause urinary obstruction and renal failure, causes significant morbidity and mortality in haematopoetic stem cell transplanted (HSCT) patients. Unfortunately, its development is difficult to predict since BK viruria is very common after HSCT and can be present in patients with and without HC. There is therefore the need to identify risk factors that may increase the risk of developing HC after HSCT. The viral load of BK-viruria, as well as BK viremia, has been monitored for this purpose. Moreover, having full myeoblative conditioning (MC) versus reduced intensity conditioning (RIC) prior to HSCT and an HLA-matched or -mismatched graft from an unrelated donor in contrast to an HLA-matched graft from a related donor have been studied as risk factors for HC. In addition, graft versus host disease has been examined, but has not been defined as a definite risk factor for HC. We conclude that the present evidence suggests that HSCT patients with BK viruria, receiving MC and an unrelated donor graft that is HLA-mismatched have an increased risk for developing HC in comparison to patients receiving RIC and an HLA-matched related donor graft.

Coexistence of Fabry disease and IgA nephropathy is rare. Moreover, the coexisting Fabry disease may be unrecognized due to unapparent clinical manifestations. We described two cases with coexisting Fabry disease and IgA nephropathy. The clinicopathological features of these two patients were studied. A 54-year-old male presented with proteinuria, hematuria, and hypertension, and a 33-year-old male presented with proteinuria without clinical signs or family history of Fabry disease. Both of them were diagnosed with IgA nephropathy at admission, whereas Fabry disease was not suspected. Subsequent immunofluorescent study confirmed the diagnosis of IgA nephropathy by showing positive staining for IgA and complement C3 in the mesangium. Meanwhile, light microscopy showed remarkable vacuolation of podocytes with mild mesangial expansion, which was characteristic of Fabry nephropathy. Further examination of toluidine blue-stained semi-thin sections and electron microscopy demonstrated blue bodies and myelin figures in the cytoplasm of podocytes, respectively. The diagnosis of coexisting Fabry disease was finally established based on deficient α-galactosidase A activity in both patients. This case study is an important reminder of the role of kidney biopsy as an indicator of Fabry disease and its rare coexistence with IgA nephropathy.

A retrospective case-control study tested the hypothesis that exposure to hydrocarbon combustion products is associated with the development of renal cell carcinoma. One control per case, matched for sex, date of birth (within 5 years) and urologist, was chosen. Controls were patients who presented with hematuria and were shown not to have a urinary tract tumour. A total of 164 cases and 161 controls responded to mailed questionnaires and telephone interviews. Smoking more than 20 cigarettes per day was associated with the presence of metastatic renal cell carcinoma (p less than 0.001). Exposure to burning coal was associated with an increased relative risk of the disease but only when the exposure occurred between the ages of 10 and 24 years (p less than 0.05). Dose-response relations were demonstrated for intensity of exposure (p less than 0.025) and duration of occupational exposure (p less than 0.05). The distribution of latent periods from first exposure to diagnosis was bimodal, with one mode at 21 to 30 years and another at 41 to 50 years. Occupational exposure to tar or pitch or both was also associated with an increased relative risk of renal cell carcinoma (p less than 0.05). PMID:2720514

Human parvovirus B19 infection causes a variety of glomerular diseases such as post-infectious acute glomerulonephritis and collapsing glomerulopathy. Although each of these appears independently, it has not been fully determined why parvovirus B19 provokes such a variety of different glomerular phenotypes. Here, we report a 68-year-old Japanese man who showed endocapillary proliferative glomerulonephritis admixed with podocytopathy in association with parvovirus B19 infection. The patient showed acute onset of heavy proteinuria, microscopic hematuria and kidney dysfunction with arthralgia and oliguria after close contact with a person suffering from erythema infectiosum. In the kidney biopsy specimen, glomeruli revealed diffuse and global endocapillary infiltration of inflammatory cells, with some also showing tuft collapse with aberrant vacuolation, swelling, and hyperplasia of glomerular epithelial cells. Immunofluorescence revealed dense granular C3 deposition that resembled the "starry sky pattern". Intravenous glucocorticoid pulse therapy followed by oral prednisolone and cyclosporine combination therapy resulted in considerable amelioration of the kidney dysfunction and urinary abnormalities. The present case reveals that parvovirus B19 infection can induce different glomerular phenotypes even in the same kidney structure. This finding may provide hints useful for the further elucidation of the pathogenesis of parvovirus B19-induced glomerular lesions. © 2018 Japanese Society of Pathology and John Wiley & Sons Australia, Ltd.

To describe the clinical and laboratory profile of focal segmental glomerulosclerosis (FSGS) of the collapsing subtype in association with infection by parvovirus B19 (PVB19). Female patient, 37 years old, mulatto, developed pharyngalgia and fever with partial improvement after penicillin. After one week we observed reduced urinary output and lower limb edema. Smoker, family and personal history negative for hypertension, diabetes or kidney disease. Patient presented with olyguria, hypertension and edema, also hypochromic microcytic hypoproliferative anemia, nephritic range proteinuria, microscopic hematuria and renal dysfunction. All rheumatologic investigation, HIV and hepatitis serology were negative. Unremarkable renal ultrasound. PCR positive for PVB19 in bone marrow aspirate and blood and renal biopsy conclusive of collapsing FSGS subtype. Spontaneous remission occurred within two weeks of the profile. The blood PVB19 PCR was repeated within a month and resulted negative. This finding demonstrated PVB19 acute infection or viral reactivation in association with collapsing FSGS. There is demonstrated the temporal association of PVB19 viremia and collapsing FSGS, due primary infection or viral reactivation. The association of collapsing FSGS and PVB19 is described in the literature, demonstrating virus presence in kidney tissue, but the real relationship of virus in the pathogenesis of this glomerulopathy remains unclear.

To find out the utility of The Paris System (TPS) in reporting urine cytology and to compare it with the reporting system currently used in our laboratory. This retrospective study was undertaken over a period of 1 year during which slides of all the urine specimens sent for cytological examination were retrieved from our laboratory filling system. They were blindly reviewed and reclassified according to TPS. Surgical follow-up was obtained from the uropathology services of our department. A total of 176 cases were meticulously reviewed. The mean age of the patients was 52 years, and 71% of cases presented with hematuria. Histopathological follow-up was available in 34 cases. Reporting by TPS detected 13.0% high-grade urothelial carcinoma (HGUC) and 5.1% atypical urothelial cells versus 7.3 and 11.9% by the current reporting system, respectively. The sensitivity and diagnostic accuracy for detecting HGUC of TPS were higher than those of our reporting system. TPS has increased the rate of detection of HGUC and reduced the rate of reporting "atypical" urothelial cells. TPS has also standardized the diagnostic criteria, thereby bringing uniformity and reproducibility into the system of reporting for urine cytology. © 2017 S. Karger AG, Basel.

We present a case of a 14-year-old girl who had a severe form of granulomatosis with polyangiitis (GPA) with extensive dermatological involvement, whose initial presentation was nonspecific leading to diagnostic confusion and initial consideration of infectious and other vasculitis causes. The patient presented with fever, congestion, malaise, and sinus pain. She was diagnosed with bacterial sinusitis and treated with antibiotics. Within weeks, she developed abdominal pain, hematuria, migratory arthritis, and palpable purpura and was diagnosed with Henoch-Schonlein purpura. She went on to develop hemoptysis and progression of the rash into erosive bullae. Investigations revealed that she was ANCA positive and had pauci-immune glomerulonephritis. Given her upper airway, pulmonary and renal involvement, and antineutrophil cytoplasmic antibodies positivity, a definitive diagnosis of a severe form of GPA was made. GPA is a chronic relapsing, life threatening vasculitis that predominantly affects small vessels. Our case demonstrates that GPA can present initially with nonspecific symptoms, including extensive dermatological involvement, leading to diagnostic confusion, and delays in treatment. In the case of a severe peripheral rash in the juvenile population and/or resistant upper airway symptoms, it is vital to consider a diagnosis of GPA to avoid serious organ or life threatening consequences.

To systematically review the safety and efficacy of lenvatinib in the treatment of patients, we retrieved all the relevant clinical trials on the adverse events (AEs) and survival outcomes of lenvatinib through PubMed, Medline, Embase, Web of Science and Cochrane Collaboration's Central register of controlled trial. Fourteen eligible studies involving a total of 978 patients were included in our analysis. The most common all-grade AEs observed in patients treated with lenvatinib were hematuria (56.6%), fatigue (52.2%) and decreased appetite (50.5%). The most frequently observed grade ≥3 AEs were thrombocytopenia (25.4%), hypertension (17.7%) and edema peripheral (15.5%). The incidences of both all-grade and high-grade hypertension were significantly increased. Meanwhile, the controlled trial suggested that progression free survival (PFS) was significantly longer in the lenvatinib group than the placebo group. Subgroup analyses showed that mean PFS for renal cell carcinoma was 10.933±1.828 months (95% CI 7.350-14.515, p < 0.001), and that for thyroid cancer was 18.344±0.083 months (95% CI 18.181-18.506, p < 0.001). In conclusion, lenvatinib is an effective agent in thyroid cancer. Early monitoring and effective management of side effects are crucial for the safe use of this drug.
