    Pelvic fracture urethral injuries are typically partial and more often complete disruptions of the most proximal bulbar and distal membranous urethra. Emergency management includes suprapubic tube placement. Subsequent primary realignment to place a urethral catheter remains a controversial topic, but what is not controversial is that when there is the development of a stricture (which is usually obliterative with a distraction defect) after suprapubic tube placement or urethral catheter removal, the standard of care is delayed urethral reconstruction with excision and primary anastomosis. This paper reviews the management of patients who suffer pelvic fracture urethral injuries and the techniques of preoperative urethral imaging and subsequent posterior urethroplasty. PMID:26691883

    INTRODUCTION Foreign bodies in the urogenital tract are not uncommon. Hairpins, glass rods, umbilical tapes, ball point pen are described in lower urogenital tract. Retained gauze piece (gossypiboma) in posterior urethra may cause diagnostic dilemma. Symptoms and investigations may mimic stricture of posterior urethra. PRESENTATION OF CASE Two cases of retained gauze pieces in the urethra are described here. The micturating cystourethrogram was suggestive of posterior urethral stricture. DISCUSSION Two cases described here had retained gauze piece as a cause of filling defect and abnormal appearance in the micturating cystourethrogram. Gossypiboma may be a possibility where posterior urethral stricture are seen after previous surgery in paediatric age group. CONCLUSION In the setting of previous urogenital surgery gossypiboma should be kept in the differential diagnosis where posterior urethral stricture are seen in the paediatric age group.

    Male anterior urethral stricture disease is a commonly encountered condition that presents to many urologists. According to a National Practice Survey of Board Certified Urologist in the United States most urologists treat on average 6-20 urethral strictures yearly. Many of those same urologists surveyed treat with repeated dilation or internal urethrotomy, despite continual recurrence of the urethral stricture. In point of fact, the urethroplasty despite its high success rate, is underutilized by many practicing urologists. Roughly half of practicing urologist do not perform urethroplasty in the United States. Clearly, the reconstructive ladder for urethral stricture management that was previously described in the literature may no longer apply in the modern era. The following article reviews the etiology, diagnosis, management and comparisons of treatment options for anterior urethral strictures. PMID:26816721

    Urethral stricture disease is relatively common and is associated with a significant financial cost and potentially debilitating outcomes. Understanding urethral stricture epidemiology is important to identify risk factors associated with the etiology or progression of the disease. This understanding may lead to better treatments and preventative measures that could ameliorate disease severity, produce better health outcomes, and reduce expenditures. We performed a comprehensive review of urethral stricture disease based on available published case series, identified gaps in knowledge of this disease, and recommend future directions for research.

    Posterior urethral stenosis can result from radical prostatectomy in approximately 5%-10% of patients (range 1.4%-29%). Similarly, 4%-9% of men after brachytherapy and 1%-13% after external beam radiotherapy will develop stenosis. The rate will be greater after combination therapy and can exceed 40% after salvage radical prostatectomy. Although postradical prostatectomy stenoses mostly develop within 2 years, postradiotherapy stenoses take longer to appear. Many result in storage and voiding symptoms and can be associated with incontinence. The evaluation consists of a workup similar to that for lower urinary tract symptoms, with additional testing to rule out recurrent or persistent prostate cancer. Treatment is usually initiated with an endoscopic approach commonly involving dilation, visual urethrotomy with or without laser treatment, and, possibly, UroLume stent placement. Open surgical urethroplasty has been reported, as well as urinary diversion for recalcitrant stenosis. A proposed algorithm illustrating a graded approach has been provided. PMID:24361008

    Introduction: Broadly defined, urethral strictures are narrowing of the urethral lumen that is surrounded by corpus spongiosum, i.e., urethral meatus through the bulbar urethra. Urethral stenosis is narrowing of the posterior urethra, i.e., membranous urethra through bladder neck/prostate junction, which is not enveloped by corpus spongiosum. The disease has significant quality of life ramifications because many times younger patients are affected by this compared to many other urological diseases. Methods: A review of the scientific literature concerning urethral stricture, stenosis, treatment, and outcomes was performed using Medline and PubMed (U.S. National Library of Medicine and the National Institutes of Health). Abstracts from scientific meetings were included in this review. Results: There is level 3 evidence regarding the etiology and epidemiology of urethral strictures, stenoses, and pelvic fracture urethral injuries. Outcomes data from literature regarding intervention for urethral stricture are largely limited to level 3 evidence and expert opinion. There is a single level 1 study comparing urethral dilation and direct vision internal urethrotomy. Urethroplasty outcomes data are limited to level 3 case series. Conclusions: Progress is being made toward consistent terminology, and nomenclature which will, in turn, help to standardize treatment within the field of urology. Treatment for urethral stricture and stenosis remains inconsistent between reconstructive and nonreconstructive urologists due to varying treatment algorithms and approaches to disease management. Tissue engineering appears to be future for reconstructive urethral surgery with reports demonstrating feasibility in the use of different tissue substitutes and grafts. PMID:26941491

    Controlled clinical trials are unusual in surgery, rare in urology, and almost non‐existent as far as the management of urethral stricture is concerned. What data there are come largely from so called “expert opinion” and the quality of this is variable. None the less, the number of so called experts, past and present, is comparatively small and in broad principle their views more or less coincide. Although this review is therefore inevitably biased, it is unlikely that expert opinion will take issue with most of the general points raised here. PMID:16891437

    The surgical treatment of urethral stricture diseases is continually evolving. Although various surgical techniques are available for the treatment of anterior urethral stricture, no one technique has been identified as the method of choice. This article provides a brief updated review of the surgical options for the management of different sites and different types of anterior urethral stricture. This review also covers present controversies in urethral reconstruction. Among the various procedures available for treating urethral stricture, one-stage buccal mucosal graft urethroplasty is currently widely used. The choice of technique for urethroplasty for an individual case largely depends on the expertise of the surgeon. Therefore, urologists working in this field should keep themselves updated on the numerous surgical techniques to deal with any condition of the urethra that might surface at the time of surgery.

    The present article reviews the literature regarding the endoscopic treatment of urethral strictures. Only few prospective randomised clinical trials with sufficient power have been performed and most of the literature provides evidence of only level 3 and 4. Since length, location, extent and calibre of the urethral stricture have an important impact on prognosis, diagnosis and the role of ultrasonography are discussed. Pathophysiology of wound healing is discussed in relation to urethrotomy, as it explains the outcomes of the procedure. Operative techniques using cold knife and laser, use of endoprostheses, indications, complications, results and postoperative management are described. The possible role of urethral catheters, hydraulic dilatations and corticosteroid applications are discussed. PMID:16970069

    Since the late 1970s different laser systems have been applied for the treatment of urethral strictures. Thermal effects adjacent on tissue have made the long term results of Nd:-YAG and Ar+ laser application discouraging. New laser systems (KTP, Excimer, Ho: YAG) still have to prove their efficacy in randomized clinical trials against cold knife urethrotomy. PMID:7941175

    Urethral strictures are difficult to manage. Some treatment modalities for urethral strictures are fraught with high patient morbidity and stricture recurrence rates; however, an extremely useful tool in the armamentarium of the Reconstructive Urologist is buccal mucosal urethroplasty. We like buccal mucosa grafts because of its excellent short and long-term results, low post-operative complication rate, and relative ease of use. We utilize it for most our bulbar urethral stricture repairs and some pendulous urethral stricture repairs, usually in conjunction with a first-stage Johanson repair. In this report, we discuss multiple surgical techniques for repair of urethral stricture disease. Diagnosis, evaluation of candidacy, surgical techniques, post-operative care, and complications are included. The goal is to raise awareness of buccal mucosa grafting for the management urethral stricture disease. PMID:22022061

    Great progress has been seen in the treatment of urethral strictures since the first endoscopic urethrotomy was performed in 1893 by Felix Martin Oberländer in Dresden, Germany. With the introduction of endoscopic laser therapy and the variety of urethral reconstruction methods other ways to treat this important urologic entity became available. Despite this progress, urethrotomy still represents the preferred treatment concept for primary, short and bulbar urethral strictures. In this study we performed a 2-year retrospective analysis of 20 patients undergoing primary endoscopic urethrotomy by single bulbar or penile narrowing. A high incidence of recurrence was seen in 70% of the patients. Nevertheless, direct vision urethrotomy represented a safe and effective transitory method to treat these patients. Moreover, 80% of the patients preferred, in cases of recurrence, a repeated urethrotomy as the treatment of choice. Although the long-term results evidence high relapse rates after the first and second procedures, there have been no sufficient data in the literature which support the use of other methods. Furthermore, primary endoscopic management of urethral strictures remains a simple, safe, and cost-effective procedure that should be indicated before more invasive approaches are taken to provide relief to these patients from this limiting problem.

    Male urethral stricture disease is prevalent and has a substantial impact on quality of life and health-care costs. Management of urethral strictures is complex and depends on the characteristics of the stricture. Data show that there is no difference between urethral dilation and internal urethrotomy in terms of long-term outcomes; success rates range widely from 8–80%, with long-term success rates of 20–30%. For both of these procedures, the risk of recurrence is greater for men with longer strictures, penile urethral strictures, multiple strictures, presence of infection, or history of prior procedures. Analysis has shown that repeated use of urethrotomy is not clinically effective or cost-effective in these patients. Long-term success rates are higher for surgical reconstruction with urethroplasty, with most studies showing success rates of 85–90%. Many techniques have been utilized for urethroplasty, depending on the location, length, and character of the stricture. Successful management of urethral strictures requires detailed knowledge of anatomy, pathophysiology, proper patient selection, and reconstructive techniques. PMID:24346008

    Although the UroLume wallstent has been proven effective in the treatment of recurrent urethral stricture, obstruction may recur in some cases. A likely cause of obstruction is hyperplastic tissue reaction, which may necessitate the removal of the stent. The hyperplastic tissue reaction may be severe, resulting in a completely obliterative stricture. Stent removal with a completely obliterative stricture and the stent in situ is a tedious job, as there is no lumen in which to place the laser fiber to cut the stent wires. We report on a patient in whom a UroLume urethral stent was placed one year ago for post-traumatic recurrent bulbomembranous urethral stricture. The stricture recurred in spite of the stent in place and the lumen was finally completely obliterated. A holmium laser was used for core through internal urethrotomy and the explantation of the stent. PMID:15147555

    Radiation as a treatment option for prostate cancer has been chosen by many patients. One of the side effects encountered are radiation-induced urethral strictures which occur in up to 11% of patients. Radiation damage has often left the irradiated field fibrotic and with poor vascularization which make these strictures a challenging entity to treat. The mainstay of urologic management remains an urethroplasty procedure for which several approaches exist with variable optimal indication. Excision and primary anastomoses are ideal for shorter bulbar strictures that comprise the majority of radiation-induced urethral strictures. One advantage of this technique is that it does not require tissue transfers and success rates of 70-95% have consistently been reported. Substitution urethroplasty using remote graft tissue such as buccal mucosa are indicated if the length of the stricture precludes a tension-free primary anastomosis. Despite the challenge of graft survival in radiation-damaged and poorly vascularized recipient tissue, up to 83% of patients have been treated successfully although the numbers described in the literature are small. The most extensive repairs involve the use of tissue flaps, for example gracilis muscle, which may be required if the involved periurethral tissue is unable to provide sufficient vascular support for a post-operative urethral healing process. In summary, radiation-induced urethral strictures are a challenging entity. Most strictures are amenable to excision and primary anastomosis (EPA) with encouraging success rates but substitution urethroplasty may be indicated when extensive repair is needed. PMID:26816812

    A prospective cross-sectional study was carried-out in the department of urology, Dhaka Medical College Hospital (DMCH) to evaluate the outcome of Laser urethrotomy for the treatment of urethral stricture. For this purpose, 30 male patients aged 15 to 60 years with short segment anterior urethral stricture (>2cm) were treated by HO:YAG Laser. The energy used for this purpose was 0.8 to 1.5 joules by LISA 80 Watt Holmium Laser machine. All patients were catheterized for less than 24 hours and were followed up for 6 to 12 months postoperatively by uroflowmetry and by retrograde with voiding cystourethrogram 3 monthly. The study revealed that out of 30 patients, 27(90%) showed good flow of urine (Qave>16.0 ml/sec) and adequate caliber urethra in retrograde urethrogram (RGU). Only 3(10%) patients showed narrow stream of urine (Qave<8.0 ml/sec) and recurrent stricture in RGU which were managed by optical internal urethrotomy (OIU) and clean intermittent self catheterization (CISC). The study showed satisfactory results in 90% cases with short term follow up. The study concludes that HO:YAG Laser urethrotomy for the treatment of short segment urethral stricture is highly effective. The study further reveals that the method is simple, safe and thus, it can be considered favorably as a new therapeutic option for the treatment of urethral stricture. However, long term follow up is necessary for making a final comment on this issue. PMID:15813486

    Staged urethroplasty is a well-known procedure for urethral reconstruction that had already been described by Russell in 1914 and was later popularized by Johanson, Turner-Warwick, Blandy, and Schreiter. It lends itself to the treatment of complex anterior urethral stricture in combination with lichen sclerosus, failed correction of hypospadias, fistula, via falsa, abscess, carcinoma, or previously unsuccessful urethroplasty. Perineal urethrostomy can be performed as a temporary or definitive measure. Some patients even decline further urethral reconstruction because they perceive subjective satisfaction after perineal urethrostomy that was originally intended to be temporary. PMID:20544335

    In 1988 the KTP-532 laser was used to ablate a series of benign urethral strictures. Rather than using a single incision as in urethrotomy, strictures were treated with 360-degree contact photoradiation. Thirty-one male patients, average age 53.2 years, received thirty-seven treatments; 6 patients underwent a second laser treatment. Stricture etiology was commonly iatrogenic (32%), traumatic (16%), and postgonococcal (10%). Stricture location included mainly bulbar (49%), membranous (20%), and penile (12%) areas. The surgical technique consisted of circumferential ablation, followed by Foley catheter placement (mean, 10 days). Follow-up on 29 of 31 patients ranged from one to sixteen months (mean 9.7). Complete success occurred in 17 patients (59%) who had no further symptoms or instrumentation. Partial success was seen in 6 patients (20.5%) with symptom, but not stricture, recurrence. Six patients (20.5%) failed therapy, requiring additional surgery or regular dilations. No complications were seen. Although longer assessment is required, KTP-532 laser ablation of urethral strictures appears efficacious. PMID:1413350

    OBJECTIVE: Evaluate the efficiency and safety of bipolar plasma vaporization using plasma-cutting and plasma-loop electrodes for the treatment of posterior urethral stricture. Compare the outcomes following bipolar plasma vaporization with conventional cold-knife urethrotomy. METHODS: A randomized trial was performed to compare patient outcomes from the bipolar and cold-knife groups. All patients were assessed at 6 and 12 months postoperatively via urethrography and uroflowmetry. At the end of the first postoperative year, ureteroscopy was performed to evaluate the efficacy of the procedure. The mean follow-up time was 13.9 months (range: 12 to 21 months). If re-stenosis was not identified by both urethrography and ureteroscopy, the procedure was considered “successful”. RESULTS: Fifty-three male patients with posterior urethral strictures were selected and randomly divided into two groups: bipolar group (n=27) or cold-knife group (n=26). Patients in the bipolar group experienced a shorter operative time compared to the cold-knife group (23.45±7.64 hours vs 33.45±5.45 hours, respectively). The 12-month postoperative Qmax was faster in the bipolar group than in the cold-knife group (15.54±2.78 ml/sec vs 18.25±2.12 ml/sec, respectively). In the bipolar group, the recurrence-free rate was 81.5% at a mean follow-up time of 13.9 months. In the cold-knife group, the recurrence-free rate was 53.8%. CONCLUSIONS: The application of bipolar plasma-cutting and plasma-loop electrodes for the management of urethral stricture disease is a safe and reliable method that minimizes the morbidity of urethral stricture resection. The advantages include a lower recurrence rate and shorter operative time compared to the cold-knife technique. PMID:26872076

    There have been a troublesome problem to treat with obliterative urethral strictures, the challenge is how to reduce wound of surgery and improve therapeutic success rates. In this study, we reported single-hospital institution case-series including 97 patients with obliterative urethral strictures were enrolled with “three lines lie within one imaginary plane (TLLWOIP)” to treat with patients with the obliterative urethral strictures. Perioperative variables and success rates were evaluated. Urinary flow rate, residual urine (RU) volume and quality-of-life score (QoLs) of patients were analyzed. In the obliterative urethral strictures, postoperative maximum urinary flow rate was 24.36±10.69 ml, and postoperative RU volume and QoLs outcomes were significantly lower than preoperative outcomes with TLLWOIP. A total of success rate was 62.9% with TLLWOIP. Our results suggested that it was ideal candidates for initial treatment with TLLWOIP for the obliterative urethral strictures. PMID:24294387

    Background To date, the morbidity of urethral stricture disease among American men has not been analyzed using national datasets. We sought to analyze the morbidity of urethral stricture disease by measuring the rates of urinary tract infections and urinary incontinence among men with a diagnosis of urethral stricture. Methods We analyzed Medicare claims data for 1992, 1995, 1998, and 2001 to estimate the rate of dual diagnoses of urethral stricture with urinary tract infection and with urinary incontinence occurring in the same year among a 5% sample of beneficiaries. Male Medicare beneficiaries receiving co-incident ICD-9 codes indicating diagnoses of urethral stricture and either urinary tract infection or urinary incontinence within the same year were counted. Results The percentage of male patients with a diagnosis of urethral stricture who also were diagnosed with a urinary tract infection was 42% in 2001, an increase from 35% in 1992. Eleven percent of male Medicare beneficiaries with urethral stricture disease in 2001 were diagnosed with urinary incontinence in the same year. This represents an increase from 8% in 1992. Conclusions Among male Medicare beneficiaries diagnosed with urethral stricture disease in 2001, 42% were also diagnosed with a urinary tract infection, and 11% with incontinence. Although the overall incidence of stricture disease decreased over this time period, these rates of dual diagnoses increased from 1992 to 2001. Our findings shed light into the health burden of stricture disease on American men. In order to decrease the morbidity of stricture disease, early definitive management of strictures is warranted.

    Objective To assess treatment strategies for seven different scenarios for treating complex pelvic fracture urethral injury (PFUI), categorised as repeat surgery for PFUI, ischaemic bulbar urethral necrosis (BUN), repair in boys and girls aged ⩽12 years, in patients with a recto-urethral fistula, or bladder neck incontinence, or with a double block at the bulbomembranous urethra and bladder neck/prostate region. Patients and methods We retrospectively reviewed the success rates and surgical procedures of these seven complex scenarios in the repair of PFUI at our institution from 2000 to 2013. Results In all, >550 PFUI procedures were performed at our centre, and 308 of these patients were classified as having a complex PFUI, with 225 patients available for follow-up. The overall success rates were 81% and 77% for primary and repeat procedures respectively. The overall success rate of those with BUN was 76%, using various methods of novel surgical techniques. Boys aged ⩽12 years with PFUI required a transpubic/abdominal approach 31% of the time, compared to 9% in adults. Young girls with PFUI also required a transpubic/abdominal urethroplasty, with a success rate of 66%. In patients with a recto-urethral fistula the success rate was 90% with attention to proper surgical principles, including a three-stage procedure and appropriate interposition. The treatment of bladder neck incontinence associated with the tear-drop deformity gave a continence rate of 66%. Children with a double block at the bulbomembranous urethra and at the bladder neck-prostate junction were all continent after a one-stage transpubic/abdominal procedure. Conclusion An understanding of complex pelvic fractures and their appropriate management can provide successful outcomes. PMID:26019978

    Advances in endoscopic instrumentation and techniques offer new alternatives for safe and effective treatment of urethral strictures. Visual internal urethrotomy, the standard treatment modality, is associated with new scar formation with stricture recurrence. This experience has led to the investigation of alternative techniques which would avoid or ameliorate this result. This article reviews the current literature and discusses these newer approaches, including balloon dilatation, laser urethrotomy, endoscopic urethroplasty, "cut to the light" and "core through" procedures, and urethral wallstent implantation.

    Objective: Management of distal anterior urethral stricture is a common problem faced by practicing urologists. Literature on urethral stricture mainly pertains to bulbar urethral stricture and pelvic fracture urethral distraction defect. The present article aims to review the management of the strictures of fossa navicularis and pendulous urethra. Materials and Methods: The literature in English language was searched from the National Library of Medicine database, using the appropriate key words for the period 1985-2010. Out of 475 articles, 115 were selected for the review based on their relevance to the topic. Results: Etiology of stricture is shifting from infective to inflammatory and iatrogenic causes. Stricture of fossa navicularis is most often caused by lichen sclerosus et atrophicus and instrumentation. Direct visual internal urethrotomy is limited to selected cases in the management of pendulous urethral stricture. With experience and identification of various prognostic factors, conservative management by dilatation and internal urethrotomy is being replaced by various reconstructive procedures, using skin flaps and grafts with high success rates. Single-stage urethroplasty is preferred over the 2-stage procedure as the latter disfigures the penis and poses sexual problems temporarily. Conclusions: Flaps or grafts are useful for single-stage reconstruction of fossa navicularis and pendulous urethral strictures. The buccal and lingual mucosa serves as a preferred resource material for providing the inner lining of the urethra. Off-the-shelf materials, such as acellular collagen matrix, are promising.

    Background: The treatment of urethral stricture in female patients is through dilatation of the urethra by tubes of increasing diameter. There are two main methods: intermittent dilatation and on demand dilatation. Objectives: The main aim of this study was to compare the results of these two methods, and to determine the best one. Patients and Methods: In this clinical trial study, we reviewed the documents of women diagnosed with urethral stricture, who came to the Baqiyatallah Clinic from 2007 and 2012. According to the method of dilatation, the patients were divided into two groups: intermittent dilatation and on demand dilatation. Patients’ data were then collected and analyzed. Results: Eighty-six patients were enrolled in the study. The mean age of the participants was 48.13 years (between 44 and 79 years). The mean urinary residual and maximum urinary flow speed changes, before and after on demand dilatation, were higher than in the intermittent method. Conclusions: For treating urethral stricture, on demand urethral dilatation is more effective than intermittent dilatation. PMID:24783171

    Introduction: We analyze the outcomes of patients with urethral stricture who underwent surgical treatment within the past 5 years. Methods: This is a retrospective study of male patients who underwent surgery for urethral stricture at our service from January 2008 to June 2012. We analyzed the comorbidities, type, length and location of the stricture and the surgical treatment outcome after endoscopic urethrotomy, urethroplasty or both. Results: In total, 45 patients with a mean age of 53.7 ± 16.7 years underwent surgical treatment for urethral stricture. Six months after surgery, 46.7% of the patients had a maximum urinary flow greater than 15 mL/s, whereas 87.3% of the patients exhibited no stricture by urethrography after the treatment. The success rate in the patients undergoing urethrotomy was 47.8% versus 86.4% in those undergoing urethroplasty (p = 0.01). Twenty percent of the patients in whom the initial urethrotomy had failed subsequently underwent urethroplasty, thereby increasing the treatment success. Conclusion: In most cases, the treatment of choice for urethral stricture should be urethroplasty. Previous treatment with urethrotomy does not appear to produce adverse effects that affect the outcome of a urethroplasty if urethrotomy failed, so urethrotomy may be indicated in patients with short strictures or in patients at high surgical risk.

    Urethral stricture disease affects many men worldwide. Traditionally, the investigation of choice has been urethrography and the management of choice has been urethrotomy/dilatation. In this review, we discuss the evidence behind the use of ultrasonography in stricture assessment. We also discuss the factors a surgeon should consider when deciding the management options with each individual patient. Not all strictures are identical and surgeons should appreciate the poor long-term results of urethrotomy/dilatation for strictures longer than 2 cm, strictures in the penile urethra, recurrent strictures, and strictures secondary to lichen sclerosus. These patients may benefit from primary urethroplasty if they have many adverse features or secondary urethroplasty after the first recurrence. PMID:26918169

    Male urethral stricture is one of the oldest known urologic diseases, and continues to be a common and challenging urologic condition. Our objective was to review all contemporary and historial articles on the topic of dilation, internal urethrotomy, and stenting of male anterior urethral strictures. An extensive review of the scientific literature concerning anterior urethral urethrotomy/dilation/stenting was performed. Articles were included that met the criteria set by the International Consultation on Urological Diseases (ICUD) urethral strictures committee and were classified by level of evidence using the Oxford Centre for Evidence-Based Medicine criteria adapted from the work of the Agency for Health Care Policy and Research as modified for use in previous ICUD projects. Using criteria set forth by the ICUD, a committee of international experts in urethral stricture disease reviewed the literature and created a consensus statement incorporating levels of evidence and expert opinion in regard to dilation, internal urethrotomy, and stenting of male anterior urethral strictures.

    2015-01-01

    Complex anterior urethral stricture disease typically manifests as a symptomatic, severely narrowed, long stricture (or multiple strictures) in which conventional excision and/or augmentation is not feasible. Overlapping buccal mucosal graft urethroplasty (OBMGU) is an innovative hybrid technique, combining the well-established principles of dorsal and ventral graft augmentation to allow single stage reconstruction of complex anterior urethral strictures. In this review, we discuss the rationale, techniques, and outcomes of OBMGU for complex anterior urethral strictures. PMID:26813234

    Three cases of urethral stricture due to balanitis xerotica obliterans (BXO) after hypospadias repair are reported. The first patient showed white, dense scarring on the prepuce before the hypospadias repair and developed a stricture of the urethra after the operation. The second and the third were uneventful for 6 and 2 years, respectively, after the hypospadias repair, and then developed urethral strictures. Pathologic diagnosis of the stenotic lesion is essential. Complete excision of the affected urethra with topical steroid ointment or sublesional triamcinolone injection is recommended for this condition. Although the complication of BXO after hypospadias repair is rare (3 out of 796 cases with hypospadias in our series), surgeons need to be aware of this condition as a cause for late onset of urethral problems.

    For bulbar urethral strictures up to 2.5 cm in length, the one-stage urethral plastic surgery with stricture excision and direct end-to-end anastomosis remains the best procedure to guarantee a high success rate. This retrospective review shows the results of 21 patients who underwent bulbar end-to-end anastomosis from 2010–2013. In 20 cases (95.3%) good results were archived. The criteria of success were identified by pre- and postoperative radiological diagnostics and uroflowmetry. PMID:26504704

    We experienced the growth of urethral hair along the urethral stricture six years after simultaneous urethral repair and reimplantation of penile prosthesis (RPP) in a patient with a urethral stricture. We detected hair in the urethra with a stricture on the bulbous urethra. Further, we performed hair removal by using a pair of cystoscopic forceps and internal urethrotomy. Then, we performed RPP, and the patient voided well; the prosthesis worked very well and without any complications. One-stage urethroplasty with a pedicle island of the penile skin and RPP in a simultaneous stage may be an option for treating the long-segment urethral stricture in the penile prosthesis patient. However, we should pay attention to the urethral hair growth that can occur after urethral repair performed using a skin graft. PMID:25606569

    The aim of the study was assessment of efficacy of internal urethrotomies made in Research Institute of Urology and city urological hospital N 47. A total of 802 endoscopic operations were performed in 644 male patients aged from 16 to 89 years (mean age 58.6 years) with urethral stricture in 1994-2004. Internal optic urethrotomy was made in 733 cases with a cold knife, in 52--with electric knife and in 17 cases--with laser. Endoscopic urethral resection was conducted in 47 cases. The strictures (0.5-8 cm long, mean 1.4 cm) located most frequently in the bulbous urethra (n=426, 66.1%). Short-term results (12 months) of endoscopic treatment of urethral strictures showed that efficacy of the primary internal urethrotomy conducted according to the authors' technique reached 80.4%. Endoscopic reoperations (from 1 to 6) were performed in 98 (19.6%) patients. A complete rehabilitation (follow-up 9 years maximum) including stenting was achieved in 95.1% patients. In 32 (4.9%) patients endoscopic and rehabilitation measures failed to bring about satisfactory clinical outcomes. These patients were treated with open urethroplasty. Thus, internal optic urethrotomy is an effective therapeutic method. After primary urethrotomy recurrences of the strictures to be reoperated reach 19.6%. These can be successfully managed by endoscopic reoperations and rehabilitation measures. PMID:18254221

    Twenty patients with Urethral stricture disease presenting with difficulty in micturition, azoospermia, and oligospermia were studied. Only 5% of our patients could firmly claim to be fertile at the time of presentation with a rise to 80% fertility rate at the end of management. Fifteen percent did not notice any change in their status. Surgical approach claimed better result over conservative management because of other complications following gonococcal infections. The need for a close forensic analysis in the determination of paternity in all cases of Urethral strictures was stressed while a treatment protocol of graft urethroplasty in all cases of traumatic rupture and dilatation in cases following inflammatory lesions of the urethra was established.

    The preferred management of urethral strictures involving long segments of anterior urethra is dorsal onlay buccal mucosa augmentation urethroplasty. This requires circumferential mobilisation of the urethra, which might cause ischaemia of the urethra in addition to chordee. The authors managed a pan anterior urethral stricture, applying a dorsolateral free graft by unilateral urethral mobilisation through a perineal approach. This is a recently described surgical technique which preserves the lateral vascular supply on one side thereby minimising ischaemia. Since circumferential mobilisation of urethra is not carried out in this technique, there are no chances of developing a chordee. Entire procedure is carried out by a perineal incision and no incision is made on the penis except for meatotomy. The pendulous urethra is accessed by penile eversion through the perineal wound. Obviating penile incisions minimises chances of wound infection and fistula formation. PMID:22689855

    Advances in endoscopic instrumentation and techniques have expanded our armamentarium for safe and effective treatment of urethral strictures. Endoscopic incision or dilation should remain the preferred treatment for uncomplicated primary strictures. Balloon dilation can be useful in the treatment of dense strictures. Incision using laser energy has yet to provide better results than procedures employing a cold knife. As such, it would be difficult to justify the added expense of laser urethrotomy. Endoscopic placement of free skin grafts into the bed of the urethra after transurethral resection or deep incision of the stricture is a novel approach that has shown a great deal of promise. Endourethroplasty is a reasonable alternative to open urethroplasty when treating long strictures, as more than 90% of the reported patients have had a successful outcome with no recurrence. However, larger experience with this procedure is necessary to verify its efficacy and for greater acceptance. The placement of indwelling stents is another new promising treatment option. Overall short-term success rates range from 75% to 100%, but the follow-up period is short, and little is known about the long-term risks of an indwelling foreign body in the urethra. Endoscopic incision via "cut-to-the-light" or "core-through" procedures is an excellent alternative in patients with obliterative strictures. Data from several centers reveal that the majority of patients gain relief of obstruction while maintaining continence and erectile potency. However, at least 25% of these patients will need further endoscopic management to maintain urethral patency. PMID:7780428

    Purpose: Treatment of urethral strictures is a major challenge in urology. For investigation of different treatment methods an animal model was developed by reproducible induction of urethral strictures in rabbits to mimic the human clinical situation. By means of this model the potential of endoluminal LDR brachytherapy using β-irradiation as prophylaxis of recurrent urethral strictures investigated. Material and Methods: A circumferential urethral stricture was induced by energy deposition using laser light application (wavelength λ=1470 nm, 10 W, 10 s, applied energy 100 J) in the posterior urethra of anaesthetized New Zealand White male rabbits. The radial light emitting fiber was introduced by means of a children resectoscope (14F). The grade of urethral stricture was evaluated in 18 rabbits using videourethroscopy and urethrography at day 28 after stricture induction. An innovative catheter was developed based on a β-irradiation emitting foil containing 32P, which was wrapped around the application system. Two main groups (each n=18) were separated. The "internal urethrotomy group" received after 28days of stricture induction immediately after surgical urethrotomy of the stricture the radioactive catheter for one week in a randomized, controlled and blinded manner. There were 3 subgroups with 6 animals each receiving 0 Gy, 15 Gy and 30 Gy. In contrast animals from the "De Nuovo group" received directly after the stricture induction (day 0) the radioactive catheter also for the duration of one week divided into the same dose subgroups. In order to determine the radiation tolerance of the urethral mucosa, additional animals without any stricture induction received a radioactive catheter applying a total dose of 30 Gy (n=2) and 15 Gy (n=1). Cystourethrography and endoscopic examination of urethra were performed on all operation days for monitoring treatment progress. Based on these investigation a classification of the stricture size was performed and

    The objective of this study was to evaluate and compare the safety and efficacy of the KTP 532 laser to direct vision internal urethrotomy (DVIU) in the management of urethral strictures. A total of 32 patients were randomized prospectively in this study, 14 DVIU and 18 KTP 532 laser. Patients were evaluated postoperatively with flowmetry and in the case of recurrence with cystourethrography at 3, 12, 24 weeks. With the KTP 532 laser complete symptomatic and urodynamic success was achieved in 15 (83%) patients at 12 and 24 weeks. Success rate was lower in the DVIU group with 9 (64%) patients at 12 weeks and 8 (57%) patients at 24 weeks. With the KTP mean preoperative peak-flow was improved from 6 cc/s to 20 cc/s at 3, 12 and 24 weeks. With DVIU mean preoperative peak-flow was improved from 5.5 cc/s to 20 cc/s at 3 weeks followed by a steady decrease to 13 cc/s at 12 weeks and to 12 cc/s 24 weeks. No complications were observed in either group of patients. Our results confirm that stricture vaporization with the KTP 532 laser is a safe and efficient procedure. It thus represents a valuable alternative in the endoscopic treatment of urethral strictures.

    Aims: To analyze the results of balloon dilatation for short segment male urethral strictures. Materials and Methods: Retrospective analysis was done of 120 patients undergoing urethral balloon dilatation since January 2004 to January 2012. The inclusion criteria for analysis was a short segment (less than 1.5 cm) stricture, exclusion criteria were pediatric, long (more than 1.5 cm), traumatic, malignant strictures. The parameters analyzed included presentation of patients, ascending urethrogram (AUG) and descending urethrogram findings, pre- and postoperative International prostate symptoms score (IPSS), uroflowmetry (Qmax), and post-void residue (PVR). Need for self calibration/ancillary procedures were assessed. Failure was defined as requirement for a subsequent endoscopic or open surgery. A urethral balloon catheter (Cook Urological, Spencer, Indiana) is passed over a guide wire after on table AUG and inflated till 180 psi for 5 minutes under fluoroscopy till waist disappears. Dilatation is followed by insertion of a Foley catheter. Patients were followed up at 1, 3, and 6 months. Results: Mean age was 49.86 years. Mean follow-up was 6 (2–60) months. IPSS improved from 21.6 preoperative to 5.6 postoperatively. Qmax increased from 5.7 to 19.1 and PVR decreased from 90.2 to 28.8 (P < 0.0001*) postoperatively. At 1, 3, and at 6 monthly follow-up, 69.2% (n = 82) patients were asymptomatic. Conclusions: Balloon dilation is a safe, well-tolerated procedure with minimal complications. Further randomized studies comparing balloon dilatation with direct internal visual urethrotomy are warranted. PMID:24311903

  7. Argon laser treatment of urethral stricture and vesical neck contracture.

    PubMed

    Adkins, W C

    1988-01-01

    The physical characteristics of the argon laser wavelength allow a precise incision with excellent hemostasis and negligible heating of adjacent tissues resulting in less scarring. These qualities are used to advantage in the treatment of strictures. The argon laser was used to perform 13 internal urethrotomies and ten vesical neck incisions. The operative method used is similar to optical internal urethrotomy. The argon probe incises hemostatically, reducing the need for extensive fulguration of tissues at the operative site and thereby reducing the tendency for more scar tissue to form and compromise the operation. The same hemostasis reduces the need for postoperative indwelling urethral catheterization. Utility of the argon device in most instances allows treatment to be conducted on an outpatient basis without general anesthesia and without use of postoperative urethral catheters, yielding an effective, cost-saving therapy.

    The number of patients with prostate cancer and benign prostatic hyperplasia is on the rise. As a result, the volume of prostate treatment and treatment-related complications is also increasing. Urethral strictures and stenoses are relatively common complications that require individualized management based on the length and location of the obstruction, and the patient's overall health, and goals of care. In general, less invasive options such as dilation and urethrotomy are preferred as first-line therapy, followed by more invasive substitution, flap, and anastomotic urethroplasty. PMID:27601967

    The association of anterior urethral valve (AUV) with posterior urethral valve (PUV) is rare. A 7-month-old infant was presented at a district hospital with episodes of acute pyelonephritis. He was treated medically and a voiding cystourethrogram (VCUG) confirmed bilateral vesico-urethral reflux. The presence of concomitant AUV and PUV was not recognized. He underwent several surgical procedures, which failed. He had reflux recurrence following two antireflux procedures. He had urinary retention after each operation, which was managed by vesicostomy and perineal urethrostomy. At the age of 3.5 years, he was referred to our paediatric urology clinic. Noticing the AUV and PUV in the past VCUG, the valves were fulgurated. Urodynamic study before and 3 months after valve ablation showed a high voiding pressure. VCUG 6 months following ablation showed no reflux, but several uroflowmetric studies showed a staccato and interrupted pattern. Empirical treatment with an alpha-blocker was started. One year after treatment, a repeat VCUG showed no reflux. Uroflowmetry and urodynamic studies returned to normal. The perineal urethrostomy was closed. The child was asymptomatic after 9 months of follow up. PMID:18947585

    2015-01-01

    Introduction: We describe the combined use of the Orandi flap and the scrotal skin advancement flap to reduce complications for pendulous urethral stricture in men >40 years old. Methods: Over the last 40 months, 10 men underwent urethroplasty for pendulous stricture by the modified Orandi urethroplasty. In this, additionally, a midline hairless scrotal skin flap of the size of the ventral skin defect on the pendulous portion was raised based on the dartos fascia. This flap was mobilized so that it reached the pendulous portion without tension and covered the penile defect. The catheter was removed after 4 weeks. Patients were followed every 3 months using uroflowmetry and the American Urological Association (AUA) symptom score. Results: The mean age was 55.5. Of the 10 patients, the etiology was post-catheterization in 5 and idiopathic in the remaining 5. Three men also had stricture extending into the bulbous urethra (repaired using buccal graft). The mean additional time needed for the flap coverage was 36.2 minutes (range: 30–45). The median follow-up was 12 months (range: 3–40). The mean postoperative symptom score was 5.2 and the mean flow rate was 20.1 mL/sec. In 2 men, the meatus got retracted to the distal penile part (probably due to downward traction by scrotal skin). No patient complained of disfigurement. Two men reported recurrence (1 each in bulbous and penile urethra). The limitations are small number of patients and the observational nature of this study. Conclusions: The intermediate-term results show that the modified Orandi urethroplasty is an acceptable treatment option with acceptable cosmetic results. PMID:26085873

    Endoscopic holmium:yttrium-aluminum-garnet (Ho:YAG) laser incision is a new method applied in pediatric urology recent years. To evaluate its therapeutic efficacy on treating the pediatric patients with urethral strictures and urethral atresias, a retrospective study was performed from June 2001 to July 2005 in a total of 28 pediatric patients who underwent endoscopic internal urethrotomy using Ho:YAG laser in our center. In these patients, 25 had urethral strictures and 3 urethral atresias. Follow-up was done ranging from 2 months to 4 years to assess the treatment. Of the 28 patients, 25 (89.3%) have achieved satisfied result without complications following initial incisions. Two patients with urethral atresias and another with long lesion of stricture (> 2 cm) have postoperative stenosis (10.7%). Among the three reoccurred patients, two were successfully reoperated by Ho:YAG laser and open end-to-end anastomosis, respectively. One patient failed to follow-up. With the advantages of safety, efficacy and minimal invasion, endoscopic Ho:YAG laser incision technique could be used as a primary treatment in urethral stricture patients and is worthy to be popularized further in pediatric surgery.

Materials and Methods Between March 2012 and February 2013, 13 patients with recurrent urethral stricture after several attempts with direct visual internal urethrotomy (DVIU) or failed urethroplasty underwent DVIU with thermally expandable, nickel-titanium alloy urethral stent (Memokath) insertion. Follow-up study time points were at 1, 3, 6, 9, and 12 months after stent insertion. Follow-up evaluation included uroflowmetry, retrograde urethrogram, plain radiography, and urinalysis. Results The mean patient age was 47.7 years (range, 18 to 74 years). The mean urethral stricture length was 5.54 cm (range, 1 to 12 cm). There were six patients with bulbar, four patients with proximal penile, one patient with distal penile, and two patients with whole penile urethral strictures, respectively. The overall success rate was 69% (9/13) and the mean postoperative peak flow rate was 17.7 mL/s (range, 6 to 28 mL/s). Major complications occurred in four patients including one patient (7.7%) with urethrocutaneous fistula induced by the stent and three patients with urethral hyperplasia. The mean follow-up duration was 8.4 months. Conclusions Our initial clinical experience indicates that thermo-expandable stents can be another temporary management option for recurrent urethral stricture patients who are unfit for or refuse urethroplasty. Distal or whole penile urethral stricture can be factors predicting poor results. PMID:24363867

    ABSTRACT Aim: To evaluate the long term outcomes of temporary urethral stent placement for the treatment of recurrent bulbar urethral stricture. Materials and Methods: Twenty-eight patients who underwent temporary polymer coated urethral stent placement due to recurrent bulbar urethral stricture between 2010 and 2014 were enrolled in the study. The long term outcomes of the patients were analyzed. Results: The mean age of the patients was 62.3±6.4 (44–81). The overall clinical success was achieved in 18 (64.2%) of the 28 patients at a median (range) follow-up of 29 (7–46) months. No patient reported discomfort at the stent site. Stone formation was observed at the urethral stent implantation area only in one patient. Stenosis occurred in the distal end of the stents in two patients and took place in bulbar urethra in seven patients after removed the stents. The mean maximum urine flow rates were 6.24±2.81mL/sec and 19.12±4.31mL/sec before and at 3 months after the procedure, respectively. Conclusion: In this study, the success rate of temporary urethral stent placement has remained at 64.2% at a median follow-up of 29 months. Therefore, our outcomes have not achieved desired success rate for the standard treatment of recurrent bulbar urethral stricture. PMID:27256191

    The use of buccal mucosa graft urethroplasty (BMGU) for bulbar urethral strictures has gained widespread popularity since the first report in 1996. Over the last two decades, there have been many modifications in the surgical technique. This, along with better understanding of urethral anatomy, has allowed the BMG to become the 'gold standard' in urethral substitution. The present article reviews the evolution and techniques of BMGU in order to answer the question - how do we optimise the use of BMGs? PMID:27489734

    The use of various grafts and flaps plays a critical role in the successful surgical management of urethral stricture disease. A thorough comprehension of relevant anatomy and principles of tissue transfer techniques are essential to understanding the appropriate use of grafts or flaps to optimize outcomes. We briefly review these principles and discuss which technique may be best suited for a given anterior urethral stricture, depending on the location and length of the stricture, the presence or absence of an intact corpus spongiosum, and the availability of adequate and healthy penile skin.

    A 2-year-old male mixed dog was referred to us for further evaluation and treatment of a 4-week-history of oliguria and abdominal distension after a surgical repair of urethral injury. To relieve the urethral stricture, we placed a self-expanding aortic stent graft extension with a partial coverage with an expanded polytetrafluoroethylene (ePTFE). After the placement of the stent, the dog presented with a normal urinary voiding, despite the presence of urinary incontinence. The current case indicates that the ePTFE-covered, self-expanding ASGE is an effective intervention for the treatment of severe urethral stricture in the dog. PMID:23676211

    Two cases involving Erbium:YAG laser incision of proximal bulbar urethral strictures are described. Erbium:YAG laser radiation with a wavelength of 2.94 μm, pulse energy of 10 mJ, and a pulse repetition rate of 15 Hz, was delivered through a 2-m-long, 250-μm-core sapphire optical fiber in contact with tissue. Total laser irradiation time was 5 min. The first patient suffering from a virgin urethral stricture was treated and is stricture-free. The second patient suffering from a recurrent urethral stricture required further treatment. This case report describes the first clinical application of the Er:YAG laser in urology.

    Purpose Prostate cancer treatment has the potential to lead to posterior urethral stricture. These strictures are sometimes recalcitrant to dilation and urethrotomy alone. We present our experience with the Urolume® stent for prostate cancer treatment related stricture. Materials and Methods A total of 38 men with posterior urethral stricture secondary to prostate cancer treatment were treated with Urolume stenting. Stents were placed in all men after aggressive urethrotomy over the entire stricture. A successfully managed stricture was defined as open and stable for greater than 6 months after any necessary secondary procedures. Results The initial success rate was 47%. After a total of 31 secondary procedures in 19 men, including additional stent placement in 8 (18%), the final success rate was 89% at a mean ± SD followup of 2.3 ± 2.5 years. Four cases (11%) in which treatment failed ultimately requiring urinary diversion (3) or salvage prostatectomy (1). Incontinence was noted in 30 men (82%), of whom 19 (63%) received an artificial urinary sphincter a mean of 7.2 ± 2.4 months after the stent. Subanalysis revealed that irradiated men had longer strictures (3.6 vs 2.0 cm, p = 0.003) and a higher post-stent incontinence rate (96% vs 50%, p <0.001) than men who underwent prostatectomy alone but the initial failure rate was similar (54% vs 50%, p = 0.4). Conclusions Urolume stenting is a reasonable option for severe post-prostate cancer treatment stricture when patients are unwilling or unable to undergo open reconstructive surgery. Incontinence should be expected. The need for additional procedures is common and in some men may be required periodically for the lifetime of the stent. PMID:21074796

    Asopa described the inlay of a graft into Snodgrass’s longitudinal urethral plate incision using a ventral sagittal urethrotomy approach in 2001. He claimed that this technique was easier to perform and led to less tissue ischemia due to no need for mobilization of the urethra. This approach has subsequently been popularized among reconstructive urologists as the dorsal inlay urethroplasty or Asopa technique. Depending on the location of the stricture, either a subcoronal circumferential incision is made for penile strictures, or a midline perineal incision is made for bulbar strictures. Other approaches for penile urethral strictures include the non-circumferential penile incisional approach and a penoscrotal approach. We generally prefer the circumferential degloving approach for penile urethral strictures. The penis is de-gloved and the urethra is split ventrally to exposure the stricture. It is then deepened to include the full thickness of the dorsal urethra. The dorsal surface is made raw and grafts are fixed on the urethral surface. Quilting sutures are placed to further anchor the graft. A Foley catheter is placed and the urethra is retubularized in two layers with special attention to the staggering of suture lines. The skin incision is then closed in layers. We have found that it is best to perform an Asopa urethroplasty when the urethral plate is ≥1 cm in width. The key to when to use the dorsal inlay technique all depends on the width of the urethral plate once the urethrotomy is performed, stricture etiology, and stricture location (penile vs. bulb).

    Introduction: to report our experience with 41 patients treated by early endoscopic realignment of complete post-traumatic rupture urethra. Materials and Methods: The study includes patients presented to our institute, between May 2004 and April 2009, with post-traumatic complete posterior urethral disruption. Preoperative retrograde urethrography, voiding cystourethrography and abdominopelvic CT were performed to evaluate the urethral defect length, the bladder neck competence, the prostate position, and the extent of the pelvic hematoma. Within the first week after trauma, antegrade and retrograde urethroscopy were performed to identify both urethral ends and insert urethral catheter. Patients were followed up by pericatheter retrograde urethrogram monthly postoperatively till catheter removal on disappearance of extravasation. Retrograde urethrography, voiding cystourethrography and urethroscopy were performed 1 month after the removal of the catheter. Follow-up abdominal ultrasound and uroflowmetry monthly till 6 months, bimonthly till 1 year, and every 3 months thereafter were encouraged. Urinary continence and postoperative erectile dysfunction were assessed by direct patient interview. Results: Forty one patients in the age group 17-61 years (mean 37.9) were treated. Patients were followed up for Conclusions: Early endoscopic realignment for complete posterior urethral rupture is a feasible technique with no or minimal intraoperative complications. The technique is successful as the definitive line of therapy in reasonable number of patients and seems to render further future interventions for inevitable urethral stricture easier.

    Giant vesico-prostatic urethral calculus is uncommon. Urethral stones rarely form primarily in the urethra, and they are usually associated with urethral strictures, posterior urethral valve or diverticula. We report a case of a 32-year-old man with giant vesico-prostatic (collar-stud) urethral stone presenting with sepsis and bladder outlet obstruction. The clinical presentation, management, and outcome of the giant prostatic urethral calculus are reviewed. PMID:22091328

    Introduction. Urethral strictures in boys denote narrowing of the urethra which can be congenital or acquired. In case of acquired strictures, the etiology is iatrogenic or traumatic and rarely infectious or inflammatory. The aim of this study was to highlight the diagnostic and therapeutic difficulties of acquired nontraumatic urethral strictures in boys in Yaoundé, Cameroon. Methodology. The authors report five cases of nontraumatic urethral strictures managed at the Pediatric Surgery Department of the YGOPH over a two-year period (November 2012–November 2014). In order to confirm the diagnosis of urethral stricture, all patients were assessed with both cystourethrography and urethrocystoscopy. Results. In all the cases the urethra was inflammatory with either a single or multiple strictures. The surgical management included internal urethrotomy (n = 1), urethral dilatation (n = 1), vesicostomy (n = 2), and urethral catheterization (n = 3). With a median follow-up of 8.2 months (4–16 months) all patients remained symptoms-free. Conclusion. The authors report the difficulties encountered in the diagnosis and management of nontraumatic urethral strictures in boys at a tertiary hospital in Yaoundé, Cameroon. The existence of an inflammatory etiology of urethral strictures in boys deserves to be considered. PMID:27239364

    Objective To evaluate the treatment effect of collagenase Clostridium histolyticum (CCH) in a rat model of urethral fibrosis. Materials and Methods Thirty male Sprague-Dawley rats (300-350 g) were divided into 5 groups. The rat urethra was injected with normal saline in the sham group and, in the other 4 groups, the rat urethra was injected with 10 μg of transforming growth factor beta 1 to create fibrosis of the urethra. Two weeks following transforming growth factor beta 1 injection, the rats were injected with varying doses of CCH or vehicles, depending on their group. The rats were then euthanized at 4 weeks after CCH or vehicle injection. Urethral tissue was harvested for histologic and molecular analyses. Type I and III collagen levels were evaluated by Western blot analysis. Results There was urethral fibrosis and to significant increase in collagen type I and III expressions in the urethral fibrosis group compared with the sham group (P <.05). Urethral injection of CCH appeared to be safe and significantly reduce urethral fibrosis as well as collagen type I and III expressions in the high-dose CCH treatment groups when compared with the treatment control group (P <.01). Conclusion This study demonstrated a beneficial effect of CCH injections in a rat model of urethral fibrosis. These findings suggest a potential role for CCH as a therapeutic option in urethral stricture patients and warrant further investigation. PMID:26126692

    Objectives: The purpose of this study is to investigate the association of glycemic control prior to TUR-P and postoperative urethral stricture development. Materials and Methods: Of the 168 patients with a diagnosis of urethral stricture, who underwent internal urethrotomy in our hospital were retrospectively analyzed for this study. 98 patients who underwent monopolar TUR-P in our hospital previously and were developed urethral stricture were divided into two groups as diabetic and nondiabetic. Based on their HbA1c concentrations, diabetics were allocated to two groups with good (HbA1c ≤6.5%) or poor (HbA1c > 6,5%) glycemic control. Time to internal urethrotomy and the other operative parameters were compared among groups. Results: Time to internal urethrotomy after TUR-P was significantly shorter in diabetic patients with poor glycemic control than Group 1 and Group 2 (P = 0,02, P = 0,012) but no significant difference was found between Group 1 and Group 2 (P = 0,368). There was no significant difference in the mean diagnosed and resected prostate wight among groups There was no significant difference in the mean resection time and the mean time to urethral catheter removal among groups. Conclusions: Especially in poor glycemic control patients, urethral stricture development was seen in the early period after TUR-P. For this reason, in the elective TUR-P scheduled poor glycemic controlled patients the operation should be done after glycemic control. PMID:25371609

    ABSTRACT Introduction Urethral stricture disease is still a major problem in men. Many procedures are available for the treatment of urethral strictures; urethral dilatation is one of the oldest. The blind dilatation of urethral strictures may be a difficult and potentially dangerous procedure. The purpose of this study was to describe safe urethral dilatation using amplatz renal dilator and to report outcomes. Materials and Methods From 2010 to 2014, a total of 26 men with primary urethral strictures were managed by urethral dilatation using amplatz renal dilators. The parameters analyzed included presentation of patients, retrograde urethrography (RGU) findings, pre-and postoperative maximum flow rate (Qmax) on uroflowmetry (UF) and post-void residual urine (PVR). Patients were followed-up at 1.6 and 12 months. The technique described in this paper enables such strictures to be safely dilated after endoscopic placement of a suitable guidewire and stylet over which amplatz renal dilators are introduced. Results The mean age of the patients was 57.6 (35–72) years. The median stricture length was 0.82 (0.6–1.5)cm. Pre-operative uroflowmetry showed Qmax of 7.00 (4–12) mL/sec and ultrasonography showed PVR of 75.00 (45–195)mL. Postoperatively, Qmax improved to 18.00 (15–22)mL/sec (p<0.001) at 1 month, 17.00 (13–21)mL/sec (p<0.001) at 6 months and 15.00 (12–17)mL/sec (p<0.001) at 12 months. The post-operative PVR values were 22.50 (10–60)mL (p<0.001), 30.00 (10–70)mL (p<0.001) and 30.00 (10–70) mL (p<0.001) at 1.6 12 months, respectively. The median procedure time was 15.00 (12–22) minutes. None of the patients had a recurrence during a 12-month period of follow-up. Conclusion Urethral dilatation with amplatz renal dilators avoids the risks associated with blind dilatation techniques. This tecnique is a safe, easy, well-tolerated and cost-effective alternative for treatment of urethral strictures. PMID:27256192

    Strictures of the urethra are the most common cause of obstructed micturition in younger men and there is frequent recurrence after initial treatment. Currently, routine repeated dilations, including intermittent self-catheterisation (ISC) are prescribed by urologists to prevent urethral stricture recurrence. There is, however, no high level evidence available supporting the effectiveness of practicing these painful techniques. Balancing efficacy, adverse effects and costs, we hypothesize that active surveillance is a better option for preventing stricture recurrence as compared with routine repeated dilations. However, well designed, adequately powered multi-center trials with comprehensive evaluation are urgently needed to confirm our hypothesis. . PMID:27576888

    Objective: To describe the safety, feasibility and outcome of redo buccal mucosal graft urethroplasty in patients presenting with recurrent anterior urethral stricture following previous failed BMG urethroplasty. Materials and Methods: This was a retrospective chart review of 21 patients with recurrent anterior urethral stricture after buccal mucosal graft urethroplasty, who underwent redo urethroplasty at our institute between January 2008 to January 2014. All patients underwent preoperative evaluation in the form of uroflowmetry, RGU, sonourethrogram and urethroscopy. Among patients with isolated bulbar urethral stricture, who had previously undergone ventral onlay, redo dorsal onlay BMG urethroplasty was done and vice versa (9+8 patients). Three patients, who had previously undergone Kulkarni-Barbagli urethroplasty, underwent dorsal free graft urethroplasty by ventral sagittal urethrotomy approach. One patient who had previously undergone urethroplasty by ASOPA technique underwent 2-stage Bracka repair. Catheter removal was done on 21st postoperative day. Follow-up consisted of uroflow, PVR and AUA-SS. Failure was defined as requirement of any post operative procedure. Results: Idiopathic urethral strictures constituted the predominant etiology. Eleven patients presented with stricture recurrence involving the entire grafted area, while the remaining 10 patients had fibrotic ring like strictures at the proximal/distal graft-urethral anastomotic sites. The success rate of redo surgery was 85.7% at a mean follow-up of 41.8 months (range: 1 yr-6 yrs). Among the 18 patients who required no intervention during the follow-up period, the graft survival was longer compared to their initial time to failure. Conclusion: Redo buccal mucosal graft urethroplasty is safe and feasible with good intermediate term outcomes. PMID:26834398

    ABSTRACT Objective To assess the outcome of single stage dorsolateral onlay buccal mucosal urethroplasty for long anterior urethral strictures (>4cm long) using a perineal incision. Materials and Methods From August 2010 to August 2013, 20 patients underwent BMG urethroplasty. The cause of stricture was Lichen sclerosis in 12 cases (60%), Instrumentation in 5 cases (25%), and unknown in 3 cases (15%). Strictures were approached through a perineal skin incision and penis was invaginated into it to access the entire urethra. All the grafts were placed dorsolaterally, preserving the bulbospongiosus muscle, central tendon of perineum and one-sided attachement of corpus spongiosum. Procedure was considered to be failure if the patient required instrumentation postoperatively. Results Mean stricture length was 8.5cm (range 4 to 12cm). Mean follow-up was 22.7 months (range 12 to 36 months). Overall success rate was 85%. There were 3 failures (meatal stenosis in 1, proximal stricture in 1 and whole length recurrent stricture in 1). Other complications included wound infection, urethrocutaneous fistula, brownish discharge per urethra and scrotal oedema. Conclusion Dorsolateral buccal mucosal urethroplasty for long anterior urethral strictures using a single perineal incision is simple, safe and easily reproducible by urologists with a good outcome.

    Objective. To determine the long-term stricture-free rate after visual internal urethrotomy following initial and follow-up urethrotomies. Methods. The records of all male patients who underwent direct visual internal urethrotomy for urethral stricture disease in our hospital between July 2004 and May 2012 were reviewed. The Kaplan-Meier method was used to analyze stricture-free probability after the first, second, third, fourth, and fifth urethrotomies. Results. A total of 301 patients were included. The overall stricture-free rate at the 36-month follow-up was 8.3% with a median time to recurrence of 10 months (95% CI of 9.5 to 10.5, range: 2–36). The stricture-free rate after one urethrotomy was 12.1% with a median time to recurrence of eight months (95% CI of 7.1–8.9). After the second urethrotomy, the stricture-free rate was 7.9% with a median time to recurrence of 10 months (95% CI of 9.3 to 10.6). After the third to fifth procedures, the stricture-free rate was 0%. There was no significant difference in the stricture-free rate between single and multiple procedures. Conclusion. The long-term stricture-free rate of visual internal urethrotomy is modest even after a single procedure. PMID:26494995

    Purpose. To quantify the quality of life (QoL) distress experienced by immediate family members of patients with urethral stricture via a questionnaire given prior to definitive urethroplasty. The emotional, social, and physical effects of urethral stricture disease on the QoL of family members have not been previously described. Materials and Methods. A questionnaire was administered prospectively to an immediate family member of 51 patients undergoing anterior urethroplasty by a single surgeon (SBB). The survey was comprised of twelve questions that addressed the emotional, social, and physical consequences experienced as a result of their loved one. Results. Of the 51 surveyed family members, most were female (92.2%), lived in the same household (86.3%), and slept in the same room as the patient (70.6%). Respondents experienced sleep disturbances (56.9%) and diminished social lives (43.1%). 82.4% felt stressed by the patient's surgical treatment, and 83.9% (26/31) felt that their intimacy was negatively impacted. Conclusions. Urethral stricture disease has a significant impact on the family members of those affected. These effects may last decades and include sleep disturbance, decreased social interactions, emotional stress, and impaired sexual intimacy. Treatment of urethral stricture disease should attempt to mitigate the impact of the disease on family members as well as the patient. PMID:27034658

    ABSTRACT Background and aims: To investigate the possible effect of resectoscope size on urethral stricture rate after monopolar TURP. Materials and Methods: A retrospective study of 71 men undergoing TURP was conducted at two centers’ from November 2009 to May 2013. The patients were divided into one of two groups according to the resectoscope diameter used for TURP. Resectoscope diameter was 24 F in group 1 (n=35) or 26 F in group 2 (n=36). Urethral catheter type, catheter removal time and energy type were kept constant for all patients. Urethral stricture formation in different localizations after TURP was compared between groups. Results: There was no significant difference between the two groups in terms of age, pre-operative prostate gland volume (PV), prostate-specific antigen (PSA), maximal urinary flow rates (Qmax), International Prostate Symptom Score (IPSS) and post-voiding residual urine volume (PVR). The resection time and weight of resected prostate tissue were similar for both groups (p>0.05). A statistically significant higher incidence of bulbar stricture was detected in group 2 compared to group1 (p=0.018). Conclusions: The use of small-diameter resectoscope shafts may cause a reduction in the incidence of uretral strictures in relation to urethral friction and mucosal damage. PMID:26401868

    This study analysed the feasibility and effectiveness of Nd-YAG laser core-through urethrotomy in the management of obliterative posttraumatic urethral strictures in children. Between May 1997 and April 2000, 61 patients underwent core-through urethrotomy in posttraumatic urethral strictures, ten of whom were children (ages 5-15 years). Three patients had had previous railroading procedures, two attempted core-through urethrotomy, and two underwent end-to-end urethroplasties. Patients were on suprapubic cystostomy for a mean period of 12 months with mean stricture length of 2 cm. Nd-YAG laser core-through urethrotomy was carried out using 600- micro m bare-contact fibre as a day care procedure. There were no intraoperative or postoperative complications. Micturating cystourethrography was performed 6 weeks following urethral catheter removal. Urethroscopy and uroflowmetry were carried out after 3 months. Mean follow-up was 24 months.Nd-YAG laser core-through urethrotomy was seen to be successful in all patients without any complications. All patients are voiding without obstructive symptoms. Four required optical urethrotomy/endoscopic dilatation at least twice. Nd-YAG laser core-through urethrotomy is a safe and effective procedure for the management of obliterative posttraumatic urethral strictures in children PMID:14579073

    Radiation therapy (RT), external beam radiation therapy (EBRT), brachytherapy (BT), photon beam therapy (PBT), high intensity focused ultrasound (HIFU), and cryotherapy are noninvasive treatment options for pelvic malignancies and prostate cancer. Though effective in treating cancer, urethral stricture disease is an underrecognized and poorly reported sequela of these treatment modalities. Studies estimate the incidence of stricture from BT to be 1.8%, EBRT 1.7%, combined EBRT and BT 5.2%, and cryotherapy 2.5%. Radiation effects on the genitourinary system can manifest early or months to years after treatment with the onus being on the clinician to investigate and rule-out stricture disease as an underlying etiology for lower urinary tract symptoms. Obliterative endarteritis resulting in ischemia and fibrosis of the irradiated tissue complicates treatment strategies, which include urethral dilation, direct-vision internal urethrotomy (DVIU), urethral stents, and urethroplasty. Failure rates for dilation and DVIU are exceedingly high with several studies indicating that urethroplasty is the most definitive and durable treatment modality for patients with radiation-induced stricture disease. However, a detailed discussion should be offered regarding development or worsening of incontinence after treatment with urethroplasty. Further studies are required to assess the nature and treatment of cryotherapy and HIFU-induced strictures. PMID:26494994

    Purpose This article describes a novel technique for the repair of penile urethral strictures and establishes the safety, feasibility, and efficacy of this innovative surgical approach. Materials and Methods Patients with urethral strictures underwent a one-sided anterior dorsal oral mucosal graft urethroplasty through a penoscrotal inversion technique. The clinical outcome was considered a failure when any instrumentation was needed postoperatively, including dilatation. Results Five patients underwent the novel procedure. The patients' mean age was 58 years. The cause of stricture was instrumentation in 2 cases (40%), lichen sclerosis in 1 case (20%), and failed hypospadias repair in 2 cases (40%). The mean stricture length was 3 cm. The overall mean (range) follow-up was 6 months (range, 3–9 months). Of the 5 patients, 4 (80%) had a successful outcome and 1 (20%) had a failed outcome. The failure was successfully treated by use of a meatotomy. Conclusions The penile inversion technique through a penoscrotal incision is a viable option for the management of penile urethral strictures with several advantages to other techniques: namely, no penile skin incision, a single-stage operation, and supine positioning.

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

    Objectives. To evaluate the results of one-stage buccal mucosal urethroplasty in treatment of long urethral strictures. Methods. This retrospective study was carried out on 117 patients with long urethral strictures who underwent one-stage transperineal urethroplasty with dorsally placed buccal mucosal grafts (BMG). Success was defined as no need for any intervention during the follow-up period. Results. Among 117 patients with mean age of 39.55 ± 15.98 years, the strictures were located in penile urethra in 46 patients (39.32%), bulbar urethra in 33 (28.20%) and were panurethral in 38 (32.48%). The etiology of the urethral stricture was sexually transmitted disease (STD) in 17 (14.53%), lichen sclerosus in 15 (12.82%), trauma in 15 (12.82%), catheterization in 13 (11.11%), transurethral resection (TUR) in 6 (5.13%), and unknown in 51 (43.59%). The mean length of strictures was 9.31 ± 2.46 centimeters. During the mean followup of 18.9 ± 6.7 months success rate was 93.94% in bulbar strictures, 97.83% in penile strictures, and 84.21% in panurethral strictures (P value: 0.061). Conclusions. The success rate of transperineal urethroplasty with dorsally placed buccal mucosal grafts is equal in different sites of strictures with different etiologies. So reconstruction of long urethral strictures may be safely and effectively performed at a simple single operative procedure using this method of urethroplasty.

    Purpose To determine the efficacy of mitomycin C in reducing the recurrence of anterior urethral stricture after internal optical urethrotomy (IOU). Materials and Methods This was a randomized controlled trial conducted in the Department of Urology at the Institute of Kidney Diseases Peshawar from March 2011 to December 2013. A total of 151 patients who completed the study were divided into two groups by the lottery method. Group A (cases) comprised 78 patients in whom mitomycin C 0.1% was injected submucosally in the stricture after conventional IOU. Group B (controls) comprised 73 patients in whom IOU only was performed. Self-clean intermittent catheterization was not offered in either group. All patients were regularly followed up for 18 months. Recurrence was diagnosed by use of retrograde urethrogram in all patients and flexible urethroscopy in selected cases. Data were collected on a structured pro forma sheet and were analyzed by SPSS. Results The mean age of the patients in group A was 37.31±10.1 years and that in group B was 40.1±11.4 years. Recurrence of urethral stricture was recorded in 11 patients (14.1%) in group A and in 27 patients (36.9%) in group B (p=0.002). The mitomycin group also showed a delay in recurrence compared with the control group (p=0.002). Conclusions Recurrence of urethral stricture is high after optical urethrotomy. Mitomycin C was found to be highly effective in preventing the recurrence of urethral stricture after IOU. PMID:26366278

    Background Posterior urethral valve presenting in adulthood is uncommon. This can be an unusual cause of primary male infertility as a result of abnormalities in sexual function. Case Presentation This report describes a 40 year old man who presented to us on account of inability to impregnate his wife after 2 years of marriage. History revealed poor stream of urine since childhood and passage of scanty ejaculate during intercourse. A micturating cystourethrogram revealed dilated posterior urethra in keeping with posterior urethral valves. Endoscopic valve ablation was done with subsequent improvement in ejaculate volume and urine stream. His spouse achieved pregnancy thereafter. Conclusion In this report, it was found that adult posterior urethral valve though uncommon may be a cause of male infertility. Restoration of fertility potential can be achieved following valve ablation. PMID:25927029

    Purpose The clinical usefulness of hyaluronic acid (HA) instillation during visual internal urethrotomy (VIU) for decreasing the incidence of recurrent urethral stricture was assessed. Materials and Methods Twenty-eight patients were treated by VIU with HA instillation between May 2007 and June 2009. After insertion of a Foley catheter following urethrotomy, HA was instilled via an 18-gauge tube catheter between the urethral lumen and Foley catheter. Seventeen cases were analyzed retrospectively 12 months postoperatively. We evaluated the success rate of this procedure by comparing retrograde urethrography (RGU) results, maximum flow rates, and postvoid residual urine volumes preoperatively and 3 and 12 months postoperatively. Success was defined as either a maximum flow rate of at least 15 ml/s or no visible urethral stricture on RGU at 12 months postoperatively. Results Total success rates were 76.5% (13/17) and 52.9% (9/17) at 3 and 12 months postoperatively, respectively. By etiology, success rates at 3 and 12 months postoperatively, respectively, were 66.7% and 33.3% for inflammation, 66.7% and 50.0% for trauma, and 83.3% and 66.7% for unknown causes. Success rates were 63.6% for strictures less than 10 mm in length and 33.3% for strictures of 10 mm or more in length at 12 months postoperatively. Success rates were 61.5% for single strictures and 25% for multiple strictures at 12 months postoperatively. Conclusions The success rate of VIU with HA instillation was not better than that observed in the literature for conventional VIU. PMID:21221206

    A total of 14 patients with stricture of the urethra underwent treatment with Nd:YAG (neodymium:YAG) laser irradiation. A new 800-micron hemispherical optical quartz fiber was used in contact technique to produce linear incisions in the scarred tissue. Within 11.2 months, median of follow up, there was improvement in the obstructive voiding symptoms in all the patients. One patient who still had mild stricture in the first follow-up cystoscopy was managed successfully with second treatment. Endoscopic application of laser energy in the contact mode facilitates the immediate vaporization and disintegration of the fibrous area and secondary reepithelization of the urethra without scarring.

    Fetal urinary tract obstruction with oligohydramnios produces pulmonary hypoplasia and renal dysplasia. Decompression of the obstructed urinary tract may restore amniotic fluid and allow lung growth, but transabdominal catheter shunt decompression is often inadequate and does not allow for cycling of the bladder, while open procedures cause significant maternal morbidity. Disruption of the anatomic obstruction, usually posterior urethral valves in a male fetus, would be ideal but has proven technically difficult. Here we describe a new technique of percutaneous fetal cystoscopy and disruption of posterior urethral valves, and the case report of our first application of this technique. We pre-sent a case of a 17-week male fetus with posterior urethral valves which underwent fetal cystoscopy for mechanical disruption of posterior urethral valves. This minimally invasive approach to disruption of posterior urethral valves in a fetus is a novel method for decompressing the urinary tract. The technique offers a minimal degree of maternal morbidity and, if instituted early enough, can restore amniotic fluid volume, avert fatal pulmonary hypoplasia and may preserve renal function.

    Objective Retrograde urethrography (RUG) is the most common and preferred imaging modality for imaging of the anterior urethral strictures despite its well-known limitations and disadvantages. Sonourethrography (SUG) was introduced in 1988 to overcome the limitations of RUG and to provide more accurate results. As proper selection of imaging modality is very important for planning the treatment, various advances in this area are required. One of the major factors for recurrence of stricture disease is spongiofibrosis. Sonoelastography (SE) is a newer technique, tried in various other pathologies. In this study, we have used this technique for the first time to assess its efficacy in the evaluation of anterior urethral stricture disease by comparison with RUG and SUG. Material and methods Between August 2014 and May 2015, 77 patients with clinical features of anterior urethral stricture disease were included in the study and evaluated by RUG followed by SUG and SE for stricture location, length, depth of spongiofibrosis and periurethral pathologies. The results were then correlated with operative and histopathological findings. Results Overall diagnostic accuracy of SE, SUG, and RGU for the estimation of stricture location, and length were estimated 92.68% vs. 91.54%, 79% vs. 78.87% and 80.48% vs. 43.66%, respectively, while for depth of spongiofibrosis SE, and SUG had accuracy rates of 87.3%, 48%, respectively. The mean length measured on SE was nearest to the mean intra-operative stricture length (21.34+11.8 mm). SE findings significantly correlated with the colour of bladder mucosa on cystoscopic examination (p=0.003) whereas the association was non-significant (p=0.127) for difficulty in incision. While a nonsignificant correlation existed between SUG findings related both to the colour of the bladder mucosa and difficulty in incision on cystoscopy, SE findings had a significant association (p<0.001) with histopathology findings for severe degree of fibrosis

    Background: Retrograde urethrogram and voiding cystourethrogram are used to define length and location of urethral stricture prior to surgery. We used a single dose of silodosin prior to VCUG to relax the bladder neck and achieve visualization of posterior urethra. Objectives: To evaluate the efficacy of silodosin in visualization of posterior urethra during VCUG, and to compare the findings with a control group. Patients and Methods: Patients were divided into two groups A and B containing 20 and 15 patients, respectively. Patients in group A were given a single dose of silodosin prior to radiological studies. Results: In group A 19 out of 20 patients were able to achieve satisfactory bladder neck opening while in group B 10 out of 15 patients were able to achieve bladder neck opening. Conclusions: Silodosin use prior to VCUG confers a statistically significant increase in bladder neck opening and visualization of posterior urethra. PMID:26543831

    Introduction: Direct visual internal urethrotomy (DVIU) followed by intermittent self-dilatation (ISD) is the most commonly performed intervention for urethral stricture disease. The objective of this paper is to outline the current scientific evidence supporting this approach for its use in the management of anterior urethral strictures. Materials and Methods: A Pubmed database search was performed with the words “internal urethrotomy” and “internal urethrotomy” self-catheterization. All papers dealing with this subject were scrutinized. Cross-references from the retrieved articles were also viewed. Only English language articles were included in the analyses. Studies were analyzed to identify predictors for success for DVIU. Results: Initial studies showed excellent outcomes with DVIU with success rates ranging from 50% to 85%. However, these studies reported only short-term results. Recent studies with longer followup have shown a poor success rate ranging from 6% to 28%. Stricture length and degree of fibrosis (luminal narrowing) were found to be predictors of response. Repeated urethrotomies were associated with poor results. Studies involving intermittent self-catheterization following DVIU have shown no role in short-term ISD with one study reporting beneficial effects if continued for more than a year. A significant number of studies have shown long-term complications with SC and high dropout rates. Conclusions: DVIU is associated with poor long-term cure rates. It remains as a treatment of first choice for bulbar urethral strictures <1 cm with minimal spongiofibrosis. There is no role for repeated urethrotomy as outcomes are uniformly poor. ISD, when used for more than a year on a weekly or biweekly basis may delay the onset of stricture recurrence. PMID:22022065

    Diagnosing urethral pathology can prove difficult, as clinically, the presentation is often nonspecific and may be suggestive of multiple etiologies. Therefore, detailed and accurate urethral imaging in both males and females is critical. Since the early 1900s, conventional imaging studies including RUG and VCUG, with adjunct cystourethroscopy, have remained the gold standard diagnostic techniques to evaluate urethral pathology. However, limitations of conventional imaging have generated interest in finding alternative imaging modalities with comparable, if not superior, diagnostic accuracy, the goal being a more complete assessment of urethral pathology and anatomy that would allow for appropriate surgical planning. Imaging modalities with three-dimensional (3D) capabilities may provide more comprehensive information regarding urethral diseases through a more detailed illustration of periurethral soft tissue structures. Whether or not these imaging modalities will replace conventional studies is unclear, though there is an increasing body of literature that support their use. PMID:27278565

    2012-01-01

    Background To present the feasibility of lingual mucosal graft urethroplasty in anterior urethral strictures and appraisal of donor site morbidity. Methods From November 2007 to December 2010, 14 patients underwent dorsal onlay lingual mucosal graft urethroplasty for anterior urethral strictures. Lingual mucosal graft was harvested from the lateral and undersurface of the tongue. Check micturating cystourethrograms were done 2 weeks after catheter removal and uroflowmetry after 3 months. Success was defined as normal uroflowmetry rates at 3 months in the absence of any postoperative instrumentation. Tongue was assessed for any residual pain, taste disturbances or restricted movement at 3 months. Results Four patients had submucosal fibrosis of the oral cavity and their buccal mucosa was unfit for grafting. Mean (range) stricture length was 5 (3–16) cm and the operation time 170 (140–210) min. Graft width averaged 1.6 cm. Average length of harvested graft was 6.5 cm. Mean duration of follow-up was 12.8 months. Two patients developed stricture at the proximal anastomotic site. There were no donor site complications. Conclusions Lingual mucosal graft harvesting is simple, gives graft lengths comparable to buccal mucosa and is associated with negligible donor site morbidity. PMID:24532928

    Purpose: During anastomotic urethroplasty for stricture urethra with false passage using standard technique, there remains a chance of anastomosis of normal distal urethra to proximal false lumen. Herein, we present a point of technique in which by using antegrade cystoscope, one cannot just identify and dissect normal anatomical proximal urethral lumen, but also perform some of the steps for anastomosis under direct vision. This will avoid making anastomosis to false lumen and thus leading to further complications. Materials and Methods: We report a case of 35-years-female who was presented to us with total mid-urethral stricture with false passage following multiple urethral dilatation attempts. We used antegrade cystoscopy during anastomotic urethroplasty to identify and dissect the proximal end of urethra thereby avoiding anastomosis to false tract. Results: We successfully performed anastomotic urethroplasty avoiding false passage. Post-operative Uroflow showed Q max of 18 ml/sec. Voiding cystourethrogram post-operatively showed anastomosis between normal anatomical lumens. Conclusion: This modification of using antegrade cystoscopy helps to identify proximal urethral end which in turn helps in avoiding anastomosis to false tract and ensures anastomosis between normal lumens.

    Purpose Although direct-vision internal urethrotomy can be performed for the management of short, bulbar urethral strictures, excision and end-to-end anastomosis remains the best procedure to guarantee a high success rate. We performed a retrospective evaluation of patients who underwent bulbar end-to-end anastomosis to assess the factors affecting surgical outcome. Materials and Methods We reviewed 33 patients with an average age of 55 years who underwent bulbar end-to-end anastomosis. Stricture etiology was blunt perineal trauma (54.6%), iatrogenic (24.2%), idiopathic (12.1%), and infection (9.1%). A total of 21 patients (63.6%) underwent urethrotomy, dilation, or multiple treatments before referral to our center. Clinical outcome was considered a treatment failure when any postoperative instrumentation was needed. Results Mean operation time was 151 minutes (range, 100 to 215 minutes) and mean excised stricture length was 1.5 cm (range, 0.8 to 2.3 cm). At a mean follow-up of 42.6 months (range, 8 to 96 months), 29 patients (87.9%) were symptom-free and required no further procedure. Strictures recurred in 4 patients (12.1%) within 5 months after surgery. Of four recurrences, one patient was managed successfully by urethrotomy, whereas the remaining three did not respond to urethrotomy or dilation and required additional urethroplasty. The recurrence rate was significantly higher in the patients with nontraumatic causes (iatrogenic in three, infection in one patient) than in the patients with traumatic etiology. Conclusions Excision and end-to-end anastomosis for short, bulbar urethral stricture has an acceptable success rate of 87.9%. However, careful consideration is needed to decide on the surgical procedure if the stricture etiology is nontraumatic. PMID:23878686

    This report outlines the case of a 3-year-old boy whose initial presentation was that of asymptomatic hypertension (lowest recording 148/90), found at preoperative check prior to stage 2-correction surgery for distal hypospadias. Upon diagnosis of true hypertension, an ultrasound of the child's renal tract showed evidence of marked hydronephrosis and calyceal dilatation. On the background of deteriorating renal function (Urea 25.5 and Creatinine 188), a Micturating Cystourethrogram was performed, demonstrating posterior urethral dilatation. With difficulties controlling blood pressure, the child was transferred to Urology care, where resection of a posterior urethral valve (PUV) was undertaken. Despite this, renal function deteriorated further and re-cystoscopy identified an anterior urethral valve (AUV), which was also resected. Renal function, although improved, remains poor and blood pressure is controlled with two anti-hypertensives. To the publisher's knowledge, the association between hypospadias, PUVs and AUVs is as yet undocumented. PMID:24964414

    This report describes the use of a tubularized random flap for the curative treatment of recurrent anterior urethral stricture. Under the condition of pendulous lithotomy and suprapubic cystostomy, the urethral stricture was removed via a midline ventral penile incision followed by elevation of the flap and insertion of an 18-Fr catheter. Subcutaneous buried interrupted sutures were used to reapproximate the waterproof tubularized neourethra and to coapt with the neourethra and each stump of the urethra, first proximally and then distally. The defect of the penile shaft was covered by advancement of the surrounding scrotal flap. The indwelling catheter was maintained for 21 days. A 9 month postoperative cystoscopy showed no flap necrosis, no mechanical stricture, and no hair growth on the lumen of the neourethra. The patient showed no voiding discomfort 6 months after the operation. The advantages of this procedure are the lack of need for microsurgery, shortening of admission, the use of only spinal anesthesia (no general anesthesia), and a relatively short operative time. The tubularized unilateral penile fasciocutaneous flap should be considered an option for initial flap urethroplasty as a curative technique. PMID:22783537

    2003-05-27

    This is a review article on treatment of bulbar urethral strictures with personal critical remarks on newer developments. As a treatment of first intention there exists 4 options : dilatation, urethrotomy, end to end anastomosis and free graft, open urethroplasty. Success rate of dilatation and visual urethrotomy after 4 years is only 20 en 40% respectively. Laser urethrotomy could not fulfill expectations. End to end anastomosis obtains a very high success rate but is only applicable for short strictures. Free graft urethroplasty obtains success rates of +/- 80%. There is considerable debate on the best material for grafting. Buccal mucosa graft is the new wave, but this is not based on scientific data. Whether this graft should be used dorsally or ventrally is also a point of discussion. In view of the good results published with both techniques it is probably of no importance. Intraluminal stents are not indicated for complicated cases and give only good results in those cases which can easily be treated with other techniques. Metal self-retaining urethral stent, resorbable stents and endoscopic urethroplasty is briefly discussed. Redo's and complicated urethral strictures need often other solutions. Here skin flap from the penile skin and scrotal flap can be used. Advantages and drawbracks of both are discussed. There is still a place for two-stage procedures in complicated redo"s. The two-stage mesh-graft urethroplasty offers advantage over the use of scrotal skin. Some other rare techniques like substitution with bowel and pudendal thigh flap, to cover deep defects, are also discussed. PMID:12806105

    The main difference between the conventional methods of urethrotomy and the laser method is that the scar tissue of the urethral stricture is not cut but removed by evaporisation. At present only neodymium: YAG and argon ion lasers are available for clinical endoscopic use. For the purpose of removing tissue neodymium: YAG lasers need irrigation with a gas in contrast to argon ion lasers that can be utilized with the well known water irrigation. Certain considerations and experiences suggest the carbon dioxide lasers to be the best ones for evaporating stricture tissue since they cause very limited zones of necrosis with immediate sealing of the wound edges. Transurethral carbon dioxide laser application, however, is still at an experimental stage, since convenient light transmission systems are not available for clinical use at the present time.

    Staged buccal mucosa graft urethroplasty has emerged as a reliable procedure for difficult anterior urethral strictures not amenable to one-stage graft or flap reconstruction. It has primarily been used for strictures and/or fistulae occurring after previous surgery for hypospadias or those related to lichen sclerosus (LS). Success rates in these patient populations have improved when compared to earlier techniques. However, prior studies have demonstrated a number of patients requiring more than two procedures to complete the reconstruction, as well as some who have been content with their voiding pattern after the first operation and therefore elected to forego second stage tubularization. In this setting, we have reviewed the surgical technique and summarized previously published work. There may be an opportunity to complete more of these repairs in two operations using additional oral mucosa at the time of tubularization. PMID:26816806

    Optical fibers have frequently been used for photothermal laser therapy due to its efficiency to deliver laser energy directly to tissue. The aim of the current study was to develop a diffusing optical fiber to achieve radially uniform light irradiation for endoscopically treating urethral stricture. The optical diffuser was fabricated by micro-machining helical patterns on the fiber surface using CO2 laser light at 5 W. Visible light emission (632 nm) and spatial emissions (including polar, azimuthal, and longitudinal emissions) of the fiber tip were evaluated to validate the performance of the fabricated diffuser. Prior to tissue tests, numerical simulation on heat distribution was developed to estimate the degree of tissue coagulation depth during interstitial coagulation. Due to a high absorption coefficient by tissue water, 1470 nm laser was used for photothermal therapy treatment of urethral stricture to obtain a more precise depth profile. For in vitro tissue tests, porcine liver tissue was irradiated with three different power levels (3, 6, and 9 W) at various irradiation times. Porcine urethral tissue was also tested with the diffuser for 10 sec at 6 W to validate the feasibility of circumferential photothermal treatment. The treated tissue was stained with hematoxylin and eosin (H and E) and then imaged with an optical transmission microscope. The spatial emission characteristics of the diffusing optical fiber presented an almost uniform power distribution along the diffuser tip (less than 10% deviation) and around its circumference (less than 5% deviation). The peak temperature in simulation model at the tissue interface between the glass-cap and the tissue was 373 K that was higher than that at the distal end. The tissue tests showed that higher power levels resulted in lower coagulation thresholds (e.g., 1 sec at 9 W vs 8 sec at 3 W). Furthermore, the coagulation depth was approximately 20% thinner than the simulation results (p<0.001). The extent of

    Purpose To evaluate the outcome of visual internal urethrotomy with a holmium:yttrium-aluminum-garnet laser along with intralesional triamcinolone injection. Materials and Methods Patients with an anterior urethral stricture less than 3 cm in length were evaluated by clinical history, physical examination, uroflowmetry, and retrograde urethrogram preoperatively. All patients were treated with holmium laser urethrotomy and intralesional triamcinolone (80 mg) injection under general or regional anesthesia. An 18 F urethral catheter was placed for 5 days. All patients were followed up for 12 months postoperatively by history, uroflowmetry, and if required, retrograde urethrogram or urethroscopy every 3 months. Results The mean age of the patients was 42.9 years (range, 14 to 70 years). The overall recurrence rate was 24%. The success rate in patients with strictures less than 1 cm in length was 95.8%, whereas that in patients with strictures of 1 to 3 cm in length was 57.7% (p=0.002). The outcome did not depend on age, duration of symptoms, etiology, or location of stricture. Conclusions Holmium laser urethrotomy with intralesional triamcinolone is a safe and effective minimally invasive therapeutic modality for urethral strictures. This procedure has an encouraging success rate, especially in those with stricture segments of less than 1 cm in length. PMID:23060998

    Objective To investigate the feasibility of removing the urinary catheter 7 days after excision and primary anastomosis (EPA) performed with the indication of anterior urethral stricture disease. Material and methods Retrospective review of medical records of the patients who had undergone EPA between January 2005 and December 2010 was performed. These patients were divided into 2 groups: Group 1 (urethral catheter removed on or before 7. postoperative day) and Group 2 (urethral catheter removed on 8. postoperative day or later). We compared 2 groups as for the frequency of extravasation as detected on retrograde pericatheter urethrogram (PUG) and recurrence rate till the last follow-up. Results PUG was performed on an average day 7 and 14 in Groups 1 (n=102) and 2 (n=134), respectively followed by removal of the catheter. Extravasation on the first PUG was detected in 6.8% of the patients in Group 1, and in 4.5% of the cases in Group 2 had extravasation on the first PUG. Urethral catheter was left in situ in these patients and a repeat PUG after one week was performed which was normal in all cases. The incidence of extravasation and recurrence rate did not differ significantly whether catheter was removed on day 7 or 14 (6.8% vs. 4.5% and 4.9% vs. 5.2% respectively) (p>0.5). Conclusion We conclude that removal of the catheter on postoperative day 7 after EPA does not increase the rate of extravasation and recurrence during long-term follow-up. Urethral catheter restricts physical activity in the postoperative period which is bothersome to the patient. Hence early removal of a catheter should be offered to men after EPA. PMID:27274892

    Objectives: Sachse cold knife is conventionally used for optical internal urethrotomy intended to manage urethral strictures and Ho: YAG laser is an alternative to it. The aim of this study was to evaluate the role of urethral stricture treatment outcomes, efficacy, and complications using cold knife and Ho: YAG (Holmium laser) for optical internal urethrotomy Materials and Methods: In this prospective study included, 90 male patients age >18 years, with diagnosis of urethral stricture admitted for internal optical urethrotomy during April 2010 to March 2012. The patients were randomized into two groups containing 45 patients each using computer generated random number. In group A (Holmium group), internal urethrotomy was done with Holmium laser and in group B (Cold knife group) Sachse cold knife was used. Patients were followed up for 6 months after surgery in Out Patient Department on 15, 30 and 180 post-operative days. At each follow up visit physical examination, and uroflowmetry was performed along with noting complaints, if any. Results: The peak flow rates (PFR) were compared between the two groups on each follow up. At 180 days (6 month interval) the difference between mean of PFR for Holmium and Cold knife group was statistically highly significant (P < 0.001). Complications were seen in 12.22% of cases. Conclusion: Both modalities are effective in providing immediate relief to patients with single and short segment (<2 cm long) urethral strictures but more sustained response was attained with Cold knife urethrotomy.

    The development of urethral stricture (US) or bladder neck contracture is a relatively uncommon but well described condition observed primarily in men. Despite familiarity with US disease, management remains challenging for urologists. Risk factors for the development of USs or bladder neck contracture include primary treatment modality, tobacco smoking, coronary artery disease and poorly controlled diabetes mellitus. Numerous treatment options exist for this condition that vary in procedural complexity, including intermittent self catheterization (CIC), serial urethral dilation, endoscopic techniques and open reconstructive repairs. Repetitive procedures for this condition may carry increased failure rates and morbidities. For the treatment of refractory or recalcitrant bladder neck contracture, newer intralesional anti-proliferative, anti-scar agents have been used in combination with transurethral bladder neck incisions to augment outcome and long-term effect. The primary focus of this systematic review of the published literature is to streamline and summarize various and newer therapeutic modalities available to manage patients with US or bladder neck contracture.

    Posterior urethral valves occur in 1 : 5000 live births. Despite the high prevalence, the few children that survive do poorly, with over 50% progressing to ESRD in 10 years. The gold standard for post-natal diagnosis is voiding cystourethrography, while pre-natal diagnosis is dependent on routine screening ultrasonography. Despite the ability to identify features of bladder outlet obstruction early in fetal development, there is no consensus on how to incorporate early detection into current screening protocols. There has yet to be a marker that allows prediction of obstruction in the absence of or prior to radiographic evidence of obstruction. With our current screening strategy, the majority of interventions are performed well after irreversible damage has occurred. Improved mortality and long term morbidity from posterior urethral valves and congenital bladder outlet obstruction will likely remain unchanged until it is possible to intervene prior to the onset of irreversible renal damage. New biologic markers and improved instrumentation will allow for more effective diagnosis and intervention at earlier stages of fetal development. PMID:21860792

    OBJECTIVE To critically evaluate the use of uroflowmetry (UF) in a large urethral stricture disease cohort as a means to monitor for stricture recurrence. MATERIALS AND METHODS This study included men that underwent anterior urethroplasty and completed a study-specific follow-up protocol. Pre- and postoperative UF studies of men found to have cystoscopic recurrence were compared to UF studies from successful repairs. UF components of interest included maximum flow rate (Qm), average flow rate (Qa), and voided volume, in addition to the novel post-UF calculated value of Qm minus Qa (Qm-Qa). Area under the receiver operating characteristic curves (AUC) of individual UF parameters was compared. RESULTS Qm-Qa had the highest AUC (0.8295) followed by Qm (0.8241). UF performed significantly better in men ≤40 with an AUC of 0.9324 and 0.9224 for Qm-Qa and Qm respectively, as compared to 0.7484 and 0.7661 in men >40. Importantly, of men found to have anatomic recurrences, only 41% had a Qm of ≤15 mL/s at time of diagnostic cystoscopy, whereas over 83% were found to have a Qm-Qa of ≤10 mL/s. CONCLUSION Qm rate alone may not be sensitive enough to replace cystoscopy when screening for stricture recurrence in all patients, especially in younger men where baseline flow rates are higher. Qm-Qa is a novel calculated UF measure that appears to be more sensitive than Qm when using UF to screen for recurrence, as it may be a better numerical representation of the shape of the voiding curve.

    Objective To identify patient and stricture characteristics predicting failure after direct vision internal urethrotomy (DVIU) for single and short (<2 cm) bulbar urethral strictures. Patients and methods We retrospectively analysed the records of adult patients who underwent DVIU between January 2002 and 2013. The patients’ demographics and stricture characteristics were analysed. The primary outcome was procedure failure, defined as the need for regular self-dilatation (RSD), redo DVIU or substitution urethroplasty. Predictors of failure were analysed. Results In all, 430 adult patients with a mean (SD) age of 50 (15) years were included. The main causes of stricture were idiopathic followed by iatrogenic in 51.6% and 26.3% of patients, respectively. Most patients presented with obstructive lower urinary tract symptoms (68.9%) and strictures were proximal bulbar, i.e. just close to the external urethral sphincter, in 35.3%. The median (range) follow-up duration was 29 (3–132) months. In all, 250 (58.1%) patients did not require any further instrumentation, while RSD was maintained in 116 (27%) patients, including 28 (6.5%) who required a redo DVIU or urethroplasty. In 64 (6.5%) patients, a redo DVIU or urethroplasty was performed. On multivariate analysis, older age at presentation [odds ratio (OR) 1.017; P = 0.03], obesity (OR 1.664; P = 0.015), and idiopathic strictures (OR 3.107; P = 0.035) were independent predictors of failure after DVIU. Conclusion The failure rate after DVIU accounted for 41.8% of our present cohort with older age at presentation, obesity, and idiopathic strictures independent predictors of failure after DVIU. This information is important in counselling patients before surgery. PMID:26609447

    Anterior urethral valve (AUV) associated with posterior urethral valves (PUVs) is an extremely rare congenital urologic anomaly resulting in lower urinary tract obstruction. We present our experience with 2 children with concomitant AUV and PUV as well as a literature review. The clinical presentation of concomitant AUV and PUV is variable. Successful endoscopic management can result in improvement in renal function, reversal of obstructive changes, and improvement or resolution of voiding dysfunction. PMID:24958476

    A premenopausal woman having a totally occlusive distal urethral stricture, with suprapubic catheter (SPC) in situ, was referred to us for a definitive procedure. On discussion of the treatment options, the patient refused for a buccal or vaginal flap procedure. Thus, a local W-V flap was fashioned from the periurethral vestibular mucosa with seemingly excellent results, both in terms of resolution of her symptoms and a forwardly directed stream of urine without incontinence.

    We reviewed the current literature on lichen sclerosus as it related to urethral stricture disease using MEDLINE and PubMed (U.S. National Library of Medicine, National Institutes of Health) up to the current time. We identified 65 reports, 40 of which were considered relevant and form the basis of this review. Lichen sclerosus is now the accepted term, and balanitis xerotica obliterans is no longer acceptable. This common chronic inflammatory skin condition, mainly affecting the genitalia, remains an enigma, with uncertain etiology, varied presentation, and multiple treatments. In the early stages of the condition, a short course of steroids may be beneficial for some patients. If persistent, patients need long-term surveillance because of the potential development of squamous cell carcinoma. If diagnosed early, lichen sclerosus can be controlled, preventing progression. But once the disease has progressed, it is very difficult to treat. Surgical treatment by circumcision can be curative if the disease is treated early when still localized. Once progression to urethral involvement has occurred, treatment is much more difficult. Meatal stenosis alone is likely to require meatotomy or meatoplasty. Treatment of the involved urethra requires urethroplasty. Single-stage and multiple-stage procedures using oral mucosa have both been reported to give acceptable results, but the use of skin, genital or nongenital, is not recommended, because being skin, it remains prone to lichen sclerosus. With extensive disease, affecting the full length of the urethra, consideration should be given to perineal urethrostomy. A significant number of patients may prefer this simpler option.

    Context: Long anterior urethral strictures are fairly common in developing world and the treatment is equally challenging. Aim: To assess the results and efficacy of Monsieur's Tunica Albuginea Urethroplasty (TAU) for anterior urethral stricture. Settings and Design: We analyzed the results in 10 consecutive patients with pan-anterior urethral stricture, who underwent Monsieur's urethroplasty. Materials and Methods: The procedure involves mobilization of strictured urethra and laying it open with a dorsal slit. Edges of the slit-open urethra are sutured to edges of the urethral groove to the tunica of corporal bodies with catheter in situ. Results were assessed postoperatively 3, 6, 9 and 12 months. Patients were categorized as success and failure by comparative analysis of patient satisfaction along with urethroscopy, retrograde urethrogram, uroflowmetry. All patients were taken for post-operative urethroscopic analysis at 6 months to allow better understanding of both successful and failed cases. Results: Mean follow-up of 15.2 (11-19) months showed an 80% success rate. Mean uroflow rate showed Qmax 24.5 cc/sec with 8 cases showing no residual or recurrent stricture. Two cases failed and required intervention. Urethroscopic visualization of the reconstruction site showed wide, patent and distensible neourethra appearing epithelized over roof formed by tunica albuginea of the corpora cavernosa in successful cases. Conclusion: Monsieur's TAU is effective technique in treatment of anterior urethral stricture especially cases with unavailable buccal mucosa, with results fairly acceptable at the end of one year.

    Purpose Lichen sclerosus (LS) in men is poorly understood. Though uncommon, it is often severe and leads to repeated surgical interventions and deterioration in quality of life. We highlight variability in disease presentation, diagnosis, and patient factors in male LS patients evaluated at a tertiary care center. Materials and Methods We retrospectively reviewed charts of male patients presenting to our reconstructive urology clinic with clinical or pathologic diagnosis of LS between 2004 and 2014. Relevant clinical and demographic information was abstracted and descriptive statistics calculated. Subgroup comparisons were made based on body mass index (BMI), urethral stricture, and pathologic confirmation of disease. Results We identified 94 patients with clinical diagnosis of LS. Seventy percent (70%) of patients in this cohort had BMI >30 kg/m2, and average age was 51.5 years. Lower BMI patients were more likely to suffer from urethral stricture disease compared to overweight counterparts (p=0.037). Patients presenting with stricture disease were more likely to be younger (p=0.003). Thirty percent (30%) of this cohort had a pathologic diagnosis of LS. Conclusions Urethral stricture is the most common presentation for men with LS. Many patients endure skin scarring and have numerous comorbidities. Patient profile is diverse, raising the concern that not all patients with clinical diagnosis of LS are suffering from identical disease processes. The rate of pathologic confirmation at a tertiary care institution is alarmingly low. Our findings support a role for increased focus on pathologic confirmation and further delineation of the subtype of disease based on location and clinical manifestations. PMID:27195319

    2016-01-01

    Purpose To present a novel modification of surgical technique to treat female urethral stricture (FUS) by a vaginal-sparing ventral buccal mucosal urethroplasty. Recurrent FUS represents an uncommon, though difficult clinical scenario to manage definitively. A variety of surgical techniques have been described to date, yet a lack of consensus on the optimal procedure persists. Materials and Methods We present a 51-year-old female with urethral stricture involving the entire urethra. Suspected etiology was iatrogenic from cystoscopy 17 years prior. Since then, the patient had undergone at least 25 formal urethral dilations and periods of self-dilation. In lithotomy position, the urethra was dilated to accommodate forceps, and ventral urethrotomy carried out sharply, exposing a bed of periurethral tissue. Buccal mucosa was harvested, and a ventral inlay technique facilitated by a nasal speculum, was used to place the graft from the proximal urethra/bladder neck to urethral meatus without a vaginal incision. Graft was sutured into place, and urethral Foley catheter inserted. Results The vaginal-sparing ventral buccal mucosal graft urethroplasty was deemed successful as of last follow-up. Flexible cystoscopy demonstrated patency of the repair at 6 months. At 10 months of follow-up, the patient was voiding well, with no urinary incontinence. No further interventions have been required. Conclusions This case describes a novel modification of surgical technique for performing buccal mucosal urethroplasty for FUS. By avoiding incision of the vaginal mucosa, benefits may include reduced: morbidity, urinary incontinence, and wound complications including urethro-vaginal fistula. PMID:27437540

    Purpose To compare urethral stricture rates in comorbid patients undergoing plasmakinetic transurethral resection of the prostate (PK-TURP) and monopolar transurethral resection of the prostate (M-TURP) for benign prostatic hyperplasia. Methods The data of 317 patients with comorbidities undergoing either PK-TURP or M-TURP from September 2008 to December 2012 were retrospectively evaluated. Preoperative and postoperative 12-month International Prostate Symptom Score, maximal flow rate, postoperative International Index of Erectile Function scores, and urethral stricture rates were evaluated. Results A total of 154 patients underwent M-TURP and 163 patients underwent PK-TURP. Urethral stricture rates were 6/154 in the M-TURP treatment arm and 17/163 in the PK-TURP treatment arm (P=0.000). In the presence of hypertension and/or coronary artery disease and/or diabetes mellitus, the risk of urethral stricture complication was significantly higher in the PK-TURP group than in the M-TURP group (P=0.000). Conclusions The risk of urethral stricture increases with PK-TURP in elderly patients with a large prostate and concomitant hypertension and/or coronary artery disease and/or diabetes mellitus. Therefore, PK-TURP should be performed cautiously in this group of benign prostatic hyperplasia patients. PMID:25325023

    Background Complex bulbar urethral strictures are a heterogeneous group, including those secondary to radiotherapy, failed previous open urethroplasty, and total bulbar necrosis following pelvic trauma. Traditional urethroplasty techniques in this group are unpredictable. We describe a novel technique of a buccal mucosa-prelaminated radial forearm free flap urethroplasty, which seeks to improve the quality of life for this group of patients. Methods Known, reliable techniques from two surgical specialties were combined to create a novel surgical solution, consisting of a radial forearm free flap prelaminated with buccal mucosa. Prospective data were collected on patient and stricture characteristics, complications, and results, including voiding flow rates, urethrography, and cystourethroscopy. Success was defined as the ability to void per urethra. The procedure was performed in four patients, previously considered unreconstructable and who were suprapubic catheter dependent. Results Microsurgical transfer was successful in all four cases. All patients were voiding per urethra and remained catheter free at a minimum of 12-month follow-up. There was no significant donor morbidity and all patients were able to return to their usual occupation. Mean voiding flow rates were 17.3 mL/s. Flexible cystoscopy revealed well-vascularized, patent neomucosa. Conclusions We demonstrate proof of concept for a novel technique of microsurgical urethroplasty. We believe this technique may have widespread application in the treatment of radiation-induced and other complex urethral strictures where traditional urethroplasty has limited success.

    Aims: A prospective study to compare the outcomes of lingual versus buccal mucosal graft urethroplasty in patients with long segment anterior urethral strictures disease. Materials and Methods: The study included 30 patients for buccal mucosal graft urethroplasty (group I) and 30 patients for lingual mucosal graft urethroplasty (group II) for treatment of long segment (>3 cm) incomplete anterior urethral stricture disease using single-stage dorsal onlay free oral mucosal graft urethroplasty by Barbagli's technique between February 2013 to September 2014. All patients underwent complete evaluation of the stricture including inspection of the oral cavity. Results: The results of urethroplasty in between two group were not significant (P > 0.05) in terms of Qmax (P = 0.63), mean postoperative AUA symptom score (P = 0.83), operative time (P = 0.302) intra operative blood loss (P = 0.708), duration of postoperative hospitalization (P = 0.83), but slurring of speech complications was seen in group II, but not in group I. Long-term complications of salivary disturbance, tightness of the mouth, persistent pain at graft site, perioral numbness, seen only in group I (BMGU). Conclusion: LMG urethroplasty is an excellent alternative to BMG urethroplasty with comparable results of urethroplasty and minimal donor site complications. PMID:27141184

    Purpose To evaluate the efficacy and safety of the Holmium: yttrium-aluminium-garnet (YAG) laser for the treatment of urethral/bladder neck strictures after high-intensity focused ultrasound for prostate cancer. Methods Between February 2007 and July 2010, Holmium: YAG laser urethrotomies were performed in eleven patients for bladder neck strictures or prostatic urethral strictures. The laser was used with a 550-µm fiber at 2 J and frequency 30 to 50 Hz. The medical records were retrospectively reviewed for medical history, perioperative and postoperative data, uroflowmetry, International Prostate Symptoms Score/quality of life, and stricture recurrence. Results At a median follow-up of 12.0 months (range, 4 to 35 months), the mean postoperative maximal flow rate and residual volume were improved significantly (P<0.05). The mean postoperative total, voiding and quality of life of international prostate symptom score were improved significantly (P<0.05). Of the 11 patients, 7 patients required one treatment, 4 patients two treatment, and 1 patients three treatment. 2 patients who had a documented urinary incontinence prior to the laser treatment subsequently required artificial urinary sphincter implantation and reported satisfaction without developing any recurrent strictures or artificial urinary sphincter erosion. All patients exhibited well-healed strictures and could void without difficulty. Conclusions Holmium: YAG laser therapy represents a safe, effective and minimally invasive treatment for urethral/bladder neck strictures occurring secondary to high-intensity focused ultrasound for prostate cancer.

    We have reviewed 233 patients with posterior urethral valves treated in a single center in Calcutta, India, over the last 20 years: 37 were neonates, 75 were between 1 and 12 months, 88 were between 1 and 5 years, and 33 were more than 5 years old when first seen. The clinical presentation and methods employed in diagnosis and assessment are described. Primary endoscopic valve ablation was performed in 140 patients (60%). One or other form of diversion was done in 100 (43%), 93 before and 7 either during or after valve ablation. The short- and long-term results have been studied. Eleven patients died during the initial hospitalization, 3 died subsequently, 15 are in end-stage renal disease, 17 are in poor health, and 18 have been totally lost to follow-up. The remaining 169 have been in good health for periods between 1 and 20 years. While our results of primary valve ablation in low-risk patients with responsible parents are as good as anywhere else in the world, we are concerned at our relatively high diversion rate and relatively poor long-term follow up; the methods being adopted to reduce these problems are discussed.

    Objective: The aim was to study the outcome of posterior urethral valve (PUV) cases treated by stepladder protocol and the prognostic factors affecting the outcome. Materials and Methods: Hospital records of all PUV patients treated by stepladder protocol between January 1992 and December 2013 were reviewed. The studied parameters were: Age at presentation, serum creatinine, types of surgical intervention, vesicoureteral reflux (VUR) on initial voiding cystourethrogram (VCUG), renal cortical scars, plasma renin activity (PRA), and glomerular filtration rate (GFR). Results: Of 396 PUV patients treated during the study period, 152 satisfied study criteria. The age at presentation ranged from 2 days to 15 years (mean 31.3 months). The mean follow-up period was 5 years (range: 2-18 years). Primary endoscopic valve ablation was the most common initial procedure. Chronic renal failure was seen in 42.7% patients at the last follow-up. Serum creatinine at presentation, initial PRA levels, initial GFR, and PRA levels at last follow-up were significant predictors of final renal outcome. Age at presentation (<1 vs. >1 year), presence/absence of VUR on initial VCUG and renal cortical scars had no significant correlation with ultimate renal function. Conclusion: Our study confirms the high prognostic significance of initial serum creatinine, PRA levels and GFR in cases with PUV. PRA also holds promise in long-term follow-up of these patients as a marker of progressive renal damage. PMID:25197189

    The cause of posterior urethral valves (PUV) is unknown, but genetic factors are suspected given their familial occurrence. We examined cases of isolated PUV to identify novel copy number variants (CNVs). We identified 56 cases of isolated PUV from all live-births in New York State (1998-2005). Samples were genotyped using Illumina HumanOmni2.5 microarrays. Autosomal and sex-linked CNVs were identified using PennCNV and cnvPartition software. CNVs were prioritized for follow-up if they were absent from in-house controls, contained ≥ 10 consecutive probes, were ≥ 20 Kb in size, had ≤ 20% overlap with variants detected in other birth defect phenotypes screened in our lab, and were rare in population reference controls. We identified 47 rare candidate PUV-associated CNVs in 32 cases; one case had a 3.9 Mb deletion encompassing BMP7. Mutations in BMP7 have been associated with severe anomalies in the mouse urethra. Other interesting CNVs, each detected in a single PUV case included: a deletion of PIK3R3 and TSPAN1, duplication/triplication in FGF12, duplication of FAT1--a gene essential for normal growth and development, a large deletion (>2 Mb) on chromosome 17q that involves TBX2 and TBX4, and large duplications (>1 Mb) on chromosomes 3q and 6q. Our finding of previously unreported novel CNVs in PUV suggests that genetic factors may play a larger role than previously understood. Our data show a potential role of CNVs in up to 57% of cases examined. Investigation of genes in these CNVs may provide further insights into genetic variants that contribute to PUV. PMID:26663319

    The objective of this study was to evaluate and compare the safety and efficacy of the KTP 532 laser to direct vision internal urethrotomy (DVIU) in the management of urethral strictures. A total of 32 patients were randomized prospectively in this study, 14 DVIU and 18 KTP 532 laser. Patients were evaluated postoperatively with flowmetry and in the case of recurrence with cystourethrography at 3, 12, 24 weeks. With the KTP 532 laser complete symptomatic and uredynamic success was achieved in 15 (83%) patients at 12 and 24 weeks. Success rate was lower in the DVIU group with 9 (64%) patients at 12 weeks and 8 (57%) patients at 24 weeks. Mean preoperative peak-flow was improved from 6 cc/s to 20 cc/s at 3, 12 and 24 weeks with the KTP laser. With DVIU mean preoperative peak-flow was improved from 5.5 cc/s to 20 cc/s at 3 weeks followed by a steady decrease to 13 cc/s at 12 weeks and to 12 cc/s 24 weeks. No complication was observed in either group of patients. Our results confirm that stricture vaporization with the KTP 532 laser is a safe and efficient procedure. The better results after laser surgery make it also a valuable alternative in the endoscopic treatment of urethral strictures. These findings suggest a favorable influence of laser surgery on wound healing with less wound contraction and scarring. The lack of contraction of laser wounds might be related to the absence and the lack of organization of myofibroblasts in laser induced lesions.

    ABSTRACT Purpose: To determine risk factors of postoperative urethral stricture (US) and vesical neck contracture (BNC) after transurethral resection of prostate (TURP) from perioperative parameters. Materials and Methods: 373 patients underwent TURP in a Chinese center for lower urinary tract symptoms suggestive of benign prostatic obstruction (LUTS/BPO), with their perioperative and follow-up clinical data being collected. Univariate analyses were used to determine variables which had correlation with the incidence of US and BNC before logistic regression being applied to find out independent risk factors. Results: The median follow-up was 29.3 months with the incidence of US and BNC being 7.8% and 5.4% respectively. Resection speed, reduction in hemoglobin (ΔHb) and hematocrit (ΔHCT) levels, incidence of urethral mucosa rupture, re-catheterization and continuous infection had significant correlation with US, while PSA level, storage score, total prostate volume (TPV), transitional zone volume (TZV), transitional zone index (TZI), resection time and resected gland weight had significant correlation with BNC. Lower resection speed (OR=0.48), urethral mucosa rupture (OR=2.44) and continuous infection (OR=1.49) as well as higher storage score (OR=2.51) and lower TPV (OR=0.15) were found to be the independent risk factors of US and BNC respectively. Conclusions: Lower resection speed, intraoperative urethral mucosa rupture and postoperative continuous infection were associated with a higher risk of US while severer storage phase symptom and smaller prostate size were associated with a higher risk of BNC after TURP.

    Abstract Background: Urethral polyps are rare benign pathologies seen in the male posterior urethra, more frequently originating from verumontanum. In this article, we aimed to discuss diagnosis and treatment of a urethral polyp causing hematuria and urinary infection in a 3-month-old male infant. This is the first case in the literature in which a urethral polyp is treated with Holmium yttrium-aluminum-garnet (YAG) laser. Case Presentation: The patient was a 3-month-old male infant, and complains were hematuria and crying during micturition. Ultrasonography and voiding cystourethrogram were used for diagnosis. Urethral polyp was observed on urethrocystoscopy. Ablation was performed with a newborn cystoscope. Conclusion: Urethral polyp can cause hematuria and urinary obstruction and should be considered in the differential diagnosis of pathologies such as posterior urethral valve and cecoureterocele that could cause infravesical obstruction. Holmium-YAG laser is a good choice of treatment with easy application possibilities using a newborn cystoscope, especially for newborns and infants who have thin urethra. PMID:27579428

    Purpose. To study the efficacy of optical internal urethrotomy with intralesional injection of Vatsala-Santosh PGI tri-inject (triamcinolone, mitomycin C, and hyaluronidase) in the treatment of anterior urethral stricture. Material and Methods. A total of 103 patients with symptomatic anterior urethral stricture were evaluated on the basis of clinical history, physical examination, uroflowmetry, and retrograde urethrogram preoperatively. All patients were treated with optical internal urethrotomy followed by injection of tri-inject at the urethrotomy site. Tri-inject was prepared by diluting the combination of triamcinolone 40 mg, mitomycin C 2 mg, and hyaluronidase 3000 in 5–10 mL of saline according to length of stricture. An indwelling 18 Fr silicone catheter was left in place for a period of 7–21 days. All patients were followed up for 6–18 months postoperatively on the basis of history, uroflowmetry, and, if required, retrograde urethrogram and micturating urethrogram every 3 months. Results. The overall recurrence rate after first OIU is 19.4% (20 out of 103 patients), that is, a success rate of 80.6%. Overall recurrence rate after second procedure was 5.8% (6 out of 103 patients), that is, a success rate of 94.2%. Conclusion. Optical internal urethrotomy with intralesional injection of Vatsala-Santosh PGI tri-inject (triamcinolone, mitomycin C, and hyaluronidase) is a safe and effective minimally invasive therapeutic modality for short segment anterior urethral strictures.

    OBJECTIVE To validate the use of the International Prostate Symptom Score (IPSS) as a stand-alone tool to detect urethral stricture recurrence following urethroplasty. MATERIALS AND METHODS This study included 393 men who had undergone anterior urethroplasty and were enrolled in a multi-institutional outcomes study. Data analyzed included pre- and post-operative answers to the IPSS in addition to findings from a same- day cystoscopy. IPSS from men found to have cystoscopic recurrence were then compared to scores from those with successful repairs, and receiver operating characteristic curves were plotted to illustrate the predictive ability of these questions to screen for cystoscopic recurrence. RESULTS Mean postoperative scores were lower (fewer symptoms) in successful repairs; IPSS improved from preoperative values regardless of recurrence. Successful repairs had significantly better degree of improvement in question #5 (assessing weak stream) compared to recurrences. Receiver operating characteristic curves demonstrated the highest area under the curve for the IPSS quality of life question (0.66) that alone outperformed the complete IPSS questionnaire (0.56). CONCLUSION The IPSS had inadequate sensitivity and specificity to be used as a stand-alone screening tool for stricture recurrence in this large cohort of men, highlighting the need to continue development of a disease-specific, validated patient-reported outcome measure.

    Posterior urethral valves (PUVs) are the most common cause of infravesical obstruction in children, whereas anterior urethral valves and/or diverticula (AUV/D) are less commonly encountered. Concomitant AUV/D and PUV is believed to be very rare and may be missed on the initial evaluation. In this review, we provide brief information on embryology of AUV/D and PUV to explain the concurrent presence of these anomalies. We also summarize the information on published cases of concomitant AUV/D and PUV in the English literature with a special focus on diagnosis and the importance of both voiding cystourethrography and careful urethrocystoscopy.

    The penile circular fasciocutaneous flap (FCF) is employed in the successful single stage reconstruction of long segment complex anterior urethral strictures especially when buccal mucosa is unavailable due to various reasons. A 65-year-old gentleman, chronic smoker and tobacco chewer, hypertensive on treatment, presented with obstructive lower urinary tract symptoms for 8 months. He had no prior urethral catheterization. On examination, he had circumcised penis, with stenosis of the external urethral meatus. Glans had no changes suggesting balanitis xerotica obliterans. Suprapubic cystostomy was done as he developed acute urinary retention during evaluation. Retrograde urethrogram (RGU) showed pan-anterior urethral stricture. He was planned for substitution urethroplasty. On oral cavity examination, he had moderate trismus with oral submucous fibrosis. As buccal mucosal graft was unavailable, he was planned for FCF. A ventral onlay tubularization FCF urethroplasty from meatus to bulbar urethra based on dartos dorsal pedicle was done. His postoperative recovery was uneventful. Pericatheter RGU did not show extravastion and he voided well with Qmax 14 ml/second. He is doing well at follow-up.

    Abstract: Background: Evaluation of the safety and efficacy of intraurethral Mitomycin C (MMC) hydrogel for prevention of post-traumatic anterior urethral stricture recurrence after internal urethrotomy. Methods: A thermoresponsive hydrogel base consisting of 0.8 mg MMC with 1cc water and propylene glycol to PF-127 poloxamer was used in theater. 40 male patients with short, non-obliterated, urethral stricture were randomized into 2 groups: control and MMC. After internal urethrotomy, the MMC group patients received the MMC-Hydrogel while the others were just catheterized. Both groups had their catheters for at least 1 week. After surgery, they were followed up by means of medical history and physical examination, monitoring voiding patterns and retrograde urethrogram at 1 month, 6 months and 1 year after surgery. Results: 40 male patients between 14 to 89 years old (Mean = 54.15) underwent internal urethrotomy. The average age for the control and MMC group was 54.55±21.25 and 53.75±24.75 respectively. In a comparison of age between the two groups, they were matched (P=0.574). Stricture length was 10.7±5.9 and 9.55±4.15 mm for the control and MMC group respectively. There were no statistically meaningful differences between the two groups (P=0.485). Fifteen patients had a history of one previous internal urethrotomy which in a comparison between the two groups meant there was no meaningful difference (P = 0.327). During postoperative follow up, total urethral stricture recurrence happened in 12 patients: 10 patients (50%) in control group and 2 patients (10%) in MMC group. The difference was statistically significant (P = 0.001). There were no significant complications associated with the MMC injection in our patients. Conclusions: Based on our results, MMC Hydrogel may have an anti-fibrotic action preventing post-traumatic anterior urethral stricture recurrence with no side effects on pre-urethral tissue. Due to our study limitations, our follow up time and the

    Between February 1987 and May 1988, 30 patients who presented with single, iatrogenic, annular strictures of the bulbar urethra were included in this prospective study. They were randomly divided into two groups; group 1: 15 patients who underwent direct-vision endoscopic urethrotomy (cold-knife incision at 12 o'clock) and group 2: 15 patients who underwent internal urethrotomy plus Nd-YAG laser. The results obtained were analyzed and compared at 1 and 2 years by clinical evaluation, uroflowmetry and retrograde-voiding urethrography. Group 1 obtained 80% good results at 1 year, falling to 60% at 2 years follow-up. Group 2 presented good results in 73.3% both at 1 and 2 years of follow-up. PMID:2261927

    The incidence of posterior urethral valves is estimated to be from 3:1000 to 8:1000 and this is one of the most common causes of obstruction of urinary tract in boys. About 13-17% of children with posterior urethral valves develop end stage renal failure. We present a  6-month-old boy with late diagnosis of posterior urtehral valves. Antenatal ultrasound investigation of the urinary tract was normal. A small degree of oligohydramnios was found during delivery. At the age of six months the boy was admitted to hospital because of urinary tract infection, hypertension (130/90 mmHg) and acute kidney injury (urea - 46 mg/dL, creatinine - 1.1 mg/dL, GFR - 35.5 mL/min/1.73 m2 ). Bilateral hydronephrosis and megaureters, low-capacity bladder with hypertrophied wall were seen on ultrasound examination. Voiding cystourethrograhy revealed vesicoureteral refluxes (III/V), hypertrophy of the bladder wall with numerous diverticula and dilated posterior urethra. During urethroscopy urethral valves were resected. Increased intravesical pressure (leak point up to 305 cm H2 O) was found on urodynamic test. Renal scintigraphy (99mTc-EC) revealed decreased intake of isotope in the left kidney (5%), and the right kidney intake was 95% ERPF. The patient was qualified for left-sided nephrectomy, which was postponed because of high leak point and high risk of worsening of vesicoureteral reflux to right kidney after nephrectomy. Anticholinergic and α-blocker treatment was started. At the age of 11 months left-side nephrectomy was performed because of recurrent urinary tract infections. After 3.5-year follow-up blood pressure, physical development, kidney function tests, and urinalysis are normal. Additionally to this investigation the significance of early diagnosis including prenatal (PUV) for further development as well as further therapeutic procedure is discussed. PMID:24519771

    Lichen sclerosus (LS) is a chronic, inflammatory disease primarily involving the genital skin and urethra in males. Historically, the treatment of this common condition was a challenge due to its uncertain etiology, variable response to therapy, and predilection to recur. The etiology of LS is still debated and has been linked to autoimmune disease, infection, trauma, and genetics. Today, topical steroids are a mainstay of therapy for patients, even in the presence of advanced disease, and can induce regression of the disease. In advanced cases, surgery may be required and range from circumcision, meatoplasty, or, in the case of advanced stricture disease, urethroplasty or perineal urethrostomy. When urethroplasty is required, the use of genital skin as a graft or flap is to be avoided due to the predilection for recurrence. Surgical management should be approached only after failure of more conservative measures due to the high risk of recurrence of LS in the repaired site despite the use of buccal grafting. LS may be associated with the development of squamous cell carcinoma and for this reason, patients should undergo biopsy when LS is suspected and long-term surveillance is recommended. PMID:26816805

    2014-01-01

    Background and objectives Approximately 20% of boys with posterior urethral valves develop ESRD; however, few factors associated with the risk of ESRD have been identified. The objective of this study was to determine if renal parenchymal area, defined as the area of the kidney minus the area of the pelvicaliceal system on first postnatal ultrasound, is associated with the risk of ESRD in infants with posterior urethral valves. Design, setting, participants, & measurements A retrospective cohort of boys who were diagnosed with posterior urethral valves at less than 6 months of age between 1988 and 2011 and followed for at least 1 year at a free-standing children’s hospital was assembled. Cox proportional hazard regression and Kaplan–Meier analysis were used to estimate the association between renal parenchymal area and time to ESRD. Cox models were adjusted for age at presentation, minimum creatinine 1 month after bladder decompression, and vesicoureteral reflux. Results Sixty patients were followed for 393 person-years. Eight patients developed ESRD. Median renal parenchymal area was 15.9 cm2 (interquartile range=13.0–21.6 cm2). Each 1-cm2 increase in renal parenchymal area was associated with a lower risk of ESRD (hazard ratio, 0.64; 95% confidence interval, 0.42 to 0.98). The rate of time to ESRD was 10 times higher in boys with renal parenchymal area<12.4 cm2 than boys with renal parenchymal area≥12.4 cm2 (P<0.001). Renal parenchymal area could best discriminate children at risk for ESRD when the minimum creatinine in the first 1 month after bladder decompression was between 0.8 and 1.1 mg/dl. Conclusion In boys with posterior urethral valves presenting during the first 6 months of life, lower renal parenchymal area is associated with an increased risk of ESRD during childhood. The predictive ability of renal parenchymal area, which is available at time of diagnosis, should be validated in a larger, prospectively-enrolled cohort. PMID:24311709

    Background Spontaneous kidney rupture could develop in the course of posterior urethral valve (PUV), the most common cause of outflow urinary tract obstruction in male infants. However, urinary extravasation is a rare complication among this group of children. Case Presentation Our case report presents diagnostic difficulties connected with spontaneous kidney rupture due to PUV in a 6 week-old infant. Due to not equivocal images, thundery course of disease and rapid deterioration in the infant's condition, the patient required an urgent laparatomy. Conclusion This case showed that the investigation of renal abnormalities during early neonatal period, is very important specifically in PUV that can lead to kidney rupture. PMID:23795264

    Objectives: The primary objective was to compare the effectiveness in pain relief of intracorpus spongiosum block (ICSB) versus intraurethral topical anesthesia (TA) using 2% lignocaine jelly for performing visual internal urethrotomy (VIU) for short segment anterior urethral strictures. Materials and Methods: It was a randomized, parallel group controlled trial. Participants are adult patients with a single anterior urethral stricture up to 2 cm in length. Patients were allocated to two intervention groups with thirty patients in each group. For anesthesia of the urethra, Group 1 patients received ICSB whereas Group 2 patients received intraurethral TA using 2% lignocaine jelly before VIU. Patient discomfort was assessed with visual analog scale (VAS) during the procedure and 1 h postprocedure. The increase in pulse rate and the change in systolic blood pressure (BP) during the procedure were recorded. The procedure was considered successful if there was absence of symptoms or signs of recurrent stricture and ability to pass freely 18Fr catheter during urethral calibration at last follow-up. Results: From March 2014 to June 2015, sixty patients were randomized into two groups of thirty patients each. The mean (±standard deviation) intraoperative VAS score was 2.8 ± 1.1 in Group 1, which was significantly less (P < 0.05) than the 5.6 ± 1.7 score in Group 2. The mean 1 h postoperative VAS score was also significantly lower in Group 1 patients (1.0 ± 1.0) than in Group 2 patients (3.2 ± 1.5). The change in pulse rate was significantly greater in Group 2 (21.3 ± 10.1 beats/min) than in Group 1 (10.6 ± 4.6 beats/min, P < 0.05). The change in systolic BP was also significantly higher in Group 2 (16.3 ± 8.6 mmHg) than in Group 1 (9.1 ± 4.4 mmHg, P < 0.05). The stricture-free rate at 6-month after VIU in Group 1 and Group 2 patients were 88.5% and 89.6%, respectively. Conclusions: ICSB has better pain control with similar complication and recurrence rate than

    To compare the efficacy of sono-urethrogram and ascending urethrogram in the evaluation of stricture urethra. Materials and Methods In this prospective study 40 patients with obstructive lower urinary tract symptoms and suspected to be having stricture urethra were subjected to ascending urethrogram and sonourethrogram. The radiologist was blinded to the findings of ascending urethrogram. All the sonourethrograms were done by the same radiologist. The findings of sonourethrogram & ascending urethrogram were compared with the findings of cystoscopy and intra-operative findings. The specificity, sensitivity,positive predictive value and negative predictive value of each modality in the diagnosis of various urethral anomalies were estimated. Results The sonourethrogram identified stricture disease in all the patients who had abnormal ascending urethrogram. In addition, other abnormalities like spongiofibrosis, diverticula and stones which were not picked up in ascending urethrogram were diagnosed by sonourethrogram. The cystoscopic and intra-operative findings with respect to stricture length, diameter and spongiofibrosis correlated well with sono-urethrogram findings. 5 patients who had stricture in the ascending urethrogram were found to be having the normal urethra in sonourethrogram and confirmed by cystoscopy. Conclusion sonourethrogram is an effective alternative to ascending urethrogram in the evaluation of stricture urethra. It is more sensitive in the diagnosis of anterior urethral strictures than posterior urethral strictures. It is superior to ascending urethrogram in the identification of spongiofibrosis, diameter and length of the stricture. The complications were lower in sonourethrogram group compared to ascending urethrogram. PMID:26005985

    Between 1981 and 1989, 28 infants less than 6 months old with posterior urethral valves underwent ultrasound evaluation as part of the initial evaluation at our hospital. The single ultrasound feature that correlated with subsequent renal function was the status of corticomedullary differentiation. The presence of corticomedullary junctions in at least 1 kidney in 17 infants was always associated with a serum creatinine level of 0.8 mg./dl. or less in long-term followup. Of 11 patients with absent corticomedullary differentiation 7 had eventual creatinine levels of greater than 0.8 mg./dl. with 5 of them suffering clinically significant renal insufficiency. An association between vesicoureteral reflux and absent corticomedullary junctions was also found. PMID:1613850

    Introduction To study the efficacy of holmium laser urethrotomy with intralesional injection of Santosh PGI tetra-inject (Triamcinolone, Mitomycin C, Hyaluronidase and N-acetyl cysteine) in the treatment of urethral strictures. Material and methods A total of 50 patients with symptomatic urethral stricture were evaluated by clinical history, physical examination, uroflowmetry and retrograde urethrogram preoperatively. All patients were treated with holmium laser urethrotomy, followed by injection of tetra-inject at the urethrotomy site. Tetra-inject was prepared by diluting acombination of 40 mg Triamcinolone, 2 mg Mitomycin, 3000 UHyaluronidase and 600 mg N-acetyl cysteine in 5–10 ml of saline, according to the stricture length. An indwelling 18 Fr silicone catheter was left in place for 7–10 days.All patients were followed-up for 6-18 months postoperatively by history, uroflowmetry, and if required, retrograde urethrogram and micturating urethrogram every 3 months. Results 41 (82%) patients had asuccessful outcome,whereas 9 (18%) had recurrences during a follow-up ranging from 6–18 months. In <1 cm length strictures, the success rate was 100%, while in 1–3 cm and >3 cm lengthsthe success rates were 81.2% and 66.7% respectively. This modality, thus, has an encouraging success rate, especially in those with short segment urethral strictures (<3 cm). Conclusions Holmium laser urethrotomy with intralesional injection ofSantosh PGI tetra-inject (Triamcinolone, Mitomycin C, Hyaluronidase, N-acetyl cysteine) is a safe and effective minimally-invasive therapeutic modality for short segment urethral strictures.

    Objective To review paediatric posterior urethral injuries and the current potential management options; because urethral injury due to pelvic fracture in children is rare and has a low incidence, the management of this type of trauma and its complications remains controversial. Methods We reviewed previous reports identified by searching the PubMed Medline electronic database for clinically relevant articles published in the past 25 years. The search was limited to the keywords ‘pediatric’, ‘pelvic fracture’, ‘urethral injury’, ‘stricture’, ‘trauma’ and ‘reconstruction’. Results Most paediatric urethral injuries are a result of pelvic fractures after high-impact blunt trauma. After the diagnosis, immediate bladder drainage via a suprapubic cystotomy, or urethral realignment, are the initial management options, except for a possible immediate primary repair in girls. The common complications of pelvic fracture-associated urethral injury include urethral stricture formation, incontinence and erectile dysfunction. Excellent results can be achieved with delayed urethroplasty for pelvic fracture-associated urethral injuries. Conclusion Traumatic injury to the paediatric urethra is rare and calls for an immediate diagnosis and management. These devastating injuries have a high complication rate and therefore a close follow-up is warranted to assure adequate delayed repair by a reconstructive urologist. PMID:26019977

    In this prospective randomized clinical trial, we aimed to evaluate the safety and efficacy of endourethrotomy with holmium:yttrium-aluminium-garnet (HO:YAG) laser and compare the outcomes with the conventional cold-knife urethrotomy. Fifty-one male patients with single, iatrogenic, annular strictures of the urethra were randomly divided into two groups; 21 patients who underwent direct-vision endoscopic urethrotomy with Ho:YAG laser (15 W; 1,200-1,400 mJ; 8-12 Hz) at 12 o'clock position (laser group) and 30 patients who underwent direct-vision endoscopic urethrotomy with cold-knife incision at 12 o'clock position (cold-knife group). The results obtained were analyzed and compared at 3 months, 6 months, 9 months, and 12 months postoperatively by clinical evaluation, uroflowmetry, and retrograde urethrographies. Variables were compared among groups using Fisher's exact and Mann Whitney U tests. There were no differences between two groups in terms of patient age, preoperative Qmax value, stricture location, and length. Operative time was shorter in laser group (16.4 ± 8.04 minutes) when compared with cold-knife group (23.8 ± 5.47 minutes) (p<0.001). Recurrence-free rate at 3 months was similar between two groups (p=0.122). However, recurrence-free rates at 6 months, 9 months, and 12 months were significantly higher in laser group when compared with cold-knife group (p values were 0.045, 0.027, and 0.04, respectively). No intra- or postoperative complications were encountered. Use of Ho:YAG laser in the management of urethral stricture disease is a safe and effective method. In addition, it provides shorter operative time and lower recurrence rate when compared with the conventional technique. PMID:22005159

    Objective: The objective of the study was to compare the outcome of buccal and lingual mucosa graft (LMG) augmentation urethroplasty along with donor sites morbidities in anterior urethra stricture. Subjects and Methods: From September 2010 to January 2014, 125 patients underwent single stage augmentation urethroplasty. They were randomly divided into two groups to receive either buccal mucosa graft (BMG) or LMG. The patients were prospectively followed for complications and outcome. Results: Baseline characteristics such as mean age, etiology, stricture length, and location were comparable in both groups. Overall success rate for Group 1 and Group 2 were 69.2% and 80%, respectively. Mean follow-up periods were 28.2 and 25 months in Group 1 and Group 2, respectively. Conclusions: LMG provides the better outcome with fewer immediate and delayed complications as compared to BMG. The length of stricture and width of graft were main factors affecting the outcome.

    Although anorectal malformations are often associated with urinary tract abnormalities, the association with posterior urethral valves is exceptionally rare. We report a unique case of a premature (35 gestational weeks) male neonate born with posterior urethral valves, bilateral dysplastic kidneys, and imperforate anus, successfully treated by Blocksom vesicostomy and left upper quadrant loop colostomy. The challenges involving placement of both stomas in a small abdominal wall of a 2200 g premature neonate are discussed. PMID:27015939

    The issues of sexual function and fertility are becoming relevant in patients with posterior urethral valves (PUV), as more of them reach adulthood. To evaluate the semen of post-pubertal patients with PUV as a determinant of future fertility, all such patients (age >16 years) attending the follow-up urology clinic of our department from 1985 to December 1999 were contacted. Of the nine patients contacted, eight agreed to form the study group. All eight patients were asked to provide a post-masturbation semen sample and urine. Semen was analysed for pH, viscosity, liquefaction time, sperm morphology, sperm count, motility, and agglutination. The patients ages ranged from 16 to 21 years (mean 17.5 years). One patient with chronic renal failure awaiting a renal transplant refused to give a semen sample; two tried but failed to ejaculate on three consecutive visits. Their urine was negative for sperm. Of the five patients who gave semen, the liquefaction time was high in two. pH ranged from 7.2 to 8, sperm counts were 24-80 million. None of the patients had oligospermia. Abnormal sperm agglutination was present in four cases; a higher percentage of immotile sperm was also present in four. Semen abnormalities in the form of increased liquefaction time, abnormal sperm agglutination, and a high percentage of immotile sperm were thus seen in the present study. The bearing of these findings on subsequent sexual function and fertility remains a matter of speculation. PMID:11956780

    Purpose The objective of this study is to evaluate the continence rate following reconstruction of the posterior urethral plate in robot-assisted laparoscopic radical prostatectomy (RLRP). Materials and Methods A retrospective analysis of 50 men with clinically localized prostate cancer who underwent RLRP was carried out. Twenty-five patients underwent RLRP using the reconstruction of the posterior aspect of the rhabdosphincter (Rocco repair). Results of 25 consecutive patients who underwent RLRP prior to the implementation of the Rocco repair were used as the control. Continence was assessed at 7, 30, 90, and 180 days following foley catheter removal using the EPIC questionnaire as well as a follow-up interview with the surgeon. Results There was no statistically significant difference between the two groups in any of the patient demographics. At 7 days, the Rocco experimental group had a continence rate of 19% vs. 38.1% in the non-Rocco control group (p = 0.306). At 30 days, the continence rate in the Rocco group was 76.2% vs. 71.4% in the non-Rocco group (p = 1). At 90 days, the values were 88% vs. 80% (p = 0.718), respectively. At 180 days, the pad-free rate was 96% in both groups. Conclusion Rocco repair offers no significant advantage in the time to recovery of continence following RLRP when continence is defined as the use of zero pads per day. On the other hand, Rocco repair was associated with increased incidence of urinary retention requiring prolonged foley catheter placement. PMID:20376897

    Background. Urethral stricture is a frequent cause of lower urinary tract obstruction worldwide. The aim of this study is to present our experience with one-stage urethroplasty. Methods. All males that underwent one-stage urethroplasty between January 2001 and December 2010 were retrospectively reviewed. Details of their biodata, clinical presentation, diagnostic investigations, operative treatment, postoperative complications, and other outcome of surgery were extracted and analyzed. Results. Ninety-one patients aged 8–76 years, (mean; 45.6 ± 19.7) with urethral stricture were studied. Postinfective strictures accounted for 58.2% and postprostatectomy strictures for 3.3%. Twenty-six (27.9%) of the strictures were in the posterior urethra of which 18 (59.2%) were posttraumatic. Fifty-seven strictures (61.3%) were in the anterior urethra of which 51 (54.8%) were postinfective. Thirty-nine (42.9%) patients had end to end anastomosis, 29 (31.9%) flap augmentation and 17 (18.7%) tabularized flap substitution, and 6 (6.6%) dorsal onlay grafts (5 with buccal mucosa and 1 with penile skin). There were 18 (19.8%) cases of wound infection, 12 (13.2%) of restricture and 6 (6.6%) cases of urethrocutaneous fistula. Satisfactory urinary stream was found in 77 (84.6%) patients. There was no mortality. Conclusion. Infection is the commonest cause of urethral stricture followed by trauma, and one-stage urethroplasty give excellent results. PMID:22567426

    Background: To compare the results of final renal function by two methods of treatment in patients diagnosed as posterior urethral valve (PUV) (valve ablation vs. vesicostomy). Materials and Methods: Fifty-four boys diagnosed with PUV participated in this study. They were divided into top two groups. Thirty-one of the total were treated with primary valve fulguration (Group 1) and 23 were treated with vesicostomy (Group 2). One-year-creatinine level and glomerular filtration rate (GFR) were measured. Also, they were taken ultrasonography detecting hydronephrosis. Data analysed in IBM SPSS21 with t-test and Chi-square test. Presented with 95% of confidence intervals. Results: Fifty-four boys diagnosed with PUV participated in this study. The mean age of patients in Group 1 was 3.8 ± 1.48 days and Group 2 was 4.7 ± 1.85 days. One-year Cr level was 1.57 ± 1.45 in Group 1 and 1.57 ± 1.45 in Group 2 which was not statistically significant (P < 0.8). Also 1-year GFR level was 31.1 ± 4.4 in Group 1 and 33 ± 4.7% in Group 2 (P < 0.10/23) in Group 2 (43.47%) had severe hydronephrosis and 14/31 (45.16%) in Group 1 had severe hydronephrosis. Graded ultrasound results were not significantly different (P = 0.24). Conclusion: The results showed no significant difference. Vesicostomy might be a more favourable method due to less complication and follow-up in early neonatal life. Hence, the condition of the patients and decision of the surgeon are effective parameters in choosing an optimal method in patients diagnosed with PUV. PMID:26712294

    Background: Posterior urethral valves (PUV) remain the most common cause of bladder outlet obstruction and renal insufficiency in male children. The aim of this study was to evaluate the presentation, management, challenges, and outcome of the disease in a Nigerian tertiary health institution. Patients and Methods: Retrospectively, medical records of male children with a diagnosis of PUVs over a 10 year period (2003-2012) were retrieved. All data in relation to the study objectives were recorded and analyzed. Results: A total of 44 patients was managed for PUV within the period. The mean age of presentation was 3.95 years with 56.8% of the patients presenting after the age of 1 year. Voiding dysfunction noted in 40 (91.0%) patients was the most common mode of presentation. The most common finding on physical examination was a palpable bladder while urinary tract infection noted in 23 (52.3%) patients was the most common complication noted. Abdominal ultrasonography revealed dilated posterior urethra in 16 (36.4%) cases, while micturating cystourethrogram revealed a dilated proximal urethra in all 35 cases in which it was done, diverticulum in 6 and vesicoureteric reflux in 9. The creatinine value at presentation ranged between 0.4 mg/dl and 4.0 mg/dl with a mean of 1.02 ± 0.93 mg/dl. Urethroscopy in 37 patients confirmed type I and type III PUV in 35 and 2 patients, respectively. Valve ablation with a diathermy bugbee electrode provided relief of obstructions in the 37 patients who underwent the procedure without any significant immediate complication. The period of follow-up ranged between 2 weeks and 3 years with a mean of 10.2 months. There was sustained improvement in urine stream, reduction in the mean creatinine concentration and incidence of UTI during follow-up. However, patients with significantly impaired renal function had a poorer outcome. Conclusion: Many patients with PUV presented late within the reviewed period. Valve ablation provided relief of

    Urethral ultrasonography is non-invasive and able to indicate the urethral lumen clearly, as well as the surrounding tissues of the posterior urethra, without contrast agent or X-ray irradiation. In this paper, we evaluate the reliability of urethral ultrasonography in the diagnosis of dysuria following bipolar transurethral plasma kinetic prostatectomy (TUPKP). A total of 120 benign prostate hyperplasia (BPH) patients with dysuria undergoing TUPKP were enrolled in this study, with a mean age of 72.8 years. All the patients received urethral ultrasonography, urethroscopy and bladder neck urethra stenosis oulectomy. Among the 120 cases, there were 22 cases of bladder neck closure, 20 bladder orifice stricture, 60 urethral stricture, 10 prostate remnants, 2 calculi in prostatic urethra, 4 dysfunction of bladder detrusor muscle and 2 flap of internal urethral orifice. χ2-test was used for the comparison of ultrasonography and urethral cystoscopy in the diagnosis of dysuria following TRPKP, and no significant difference was found between two diagnostic tools (χ 2 = 0.94, P > 0.05). Urethral ultrasonography is a reliable and minimally invasive diagnostic tool for dysuria following TUPKP and is conducive to early treatment of dysuria following prostatectomy. PMID:27163308

    Aims: Study on prognostic significance of antenatal ultrasonography and renin angiotensin system activation in predicting disease severity in posterior urethral valves. Materials and Methods: Antenatally diagnosed hydronephrosis patients were included. Postnatally, they were divided into two groups, posterior urethral valve (PUV) and non-PUV. The studied parameters were: Gestational age at detection, surgical intervention, ultrasound findings, cord blood and follow up plasma renin activity (PRA) values, vesico-ureteric reflux (VUR), renal scars, and glomerular filtration rate (GFR). Results: A total of 25 patients were included, 10 PUV and 15 non-PUV. All infants with PUV underwent primary valve incision. GFR was less than 60 ml/min/1.73 m2 body surface area in 4 patients at last follow-up. Keyhole sign, oligoamnios, absent bladder cycling, and cortical cysts were not consistent findings on antenatal ultrasound in PUV. Cord blood PRA was significantly higher (P < 0.0001) in PUV compared to non-PUV patients. Gestational age at detection of hydronephrosis, cortical cysts, bladder wall thickness, and amniotic fluid index were not significantly correlated with GFR while PRA could differentiate between poor and better prognosis cases with PUV. Conclusions: Ultrasound was neither uniformly useful in diagnosing PUV antenatally, nor differentiating it from cases with non-PUV hydronephrosis. In congenital hydronephrosis, cord blood PRA was significantly higher in cases with PUV compared to non-PUV cases and fell significantly after valve ablation. Cord blood PRA could distinguish between poor and better prognosis cases with PUV. PMID:25829668

    2014-01-01

    Distal urethral strictures involving the fossa navicularis and meatus represent a unique subset of urethral strictures that are particularly challenging to reconstructive urologists. Management of distal urethral strictures must take into account not only maintenance of urethral patency but also glans cosmesis. A variety of therapeutic approaches exist for the management of distal urethral strictures, including dilation, meatotomy, extended meatotomy, flap urethroplasty, and substitution grafting. Common etiologies for distal urethral strictures include lichen sclerosus, instrumentation, and prior hypospadias repair. Proper patient selection is paramount to the ultimate success and durability of the treatment, which should be individualized and include an assessment of the stricture etiology, location, and burden, and patient-centered goals of care.

    2011-01-01

    Introduction: Treatment of panurethral stricture is considered a surgical challenge. We searched the literature to present a comprehensive review. Materials and Methods: A review of literature was performed using MEDLINE/PubMed database using terms “urethral stricture” and “urethroplasty”. Only articles published between 1990 and 2009 and written in English language were included in the review. Results: The main causes of panurethral strictures are previous catheterization, urethral surgery, and lichen sclerosus. The treatment of each individual case has to be tailored according to the etiology, history of previous urethral surgeries, availability of local tissues for flap harvesting, availability of appropriate donor tissue, and the expertise of the treating surgeon. In patients with complicated strictures, previously failed urethroplasties and in patients with poor quality of urethral plate two-stage surgery is a better option. In all other situations, either a flap or graft urethroplasty or if adequate tissue is not available then combination of flap and graft gives reasonable success rates. Conclusions: Panurethral strictures are relatively less common. For successful results, the surgeon should be experienced and should be familiar with all the treatment modalities. PMID:22022063

    Purpose This study aims to evaluate the endoscopic morphological features of congenital posterior urethral obstructions in boys with refractory daytime urinary incontinence and/or nocturnal enuresis. Patients and Methods A total of 54 consecutive patients underwent endoscopy and were diagnosed with a posterior urethral valve (PUV) (types 1-4). PUV type 1 was classified as severe, moderate, or mild. A transurethral incision (TUI) was mainly performed for anterior wall lesions of the PUV. Voiding cystourethrography and pressure flow studies (PFS) were performed before and 3 to 4 months after TUI. Clinical symptoms were evaluated 6 months after TUI, and outcomes were assessed according to PFS waveform pattern groups (synergic pattern [SP] and dyssynergic pattern [DP]). Results All patients had PUV type 1 and/or 3 (i.e., n = 34 type 1, 7 type 3, and 13 types 1 and 3). There were severe (n = 1), moderate (n = 21), and mild (n = 25) cases of PUV type 1. According to PFS, SP and DP were present in 43 and 11 patients, respectively. TUI was effective in the SP group and symptoms improved in 77.4 and 69.3% of patients with daytime incontinence and nocturnal enuresis, respectively. Almost no effect was observed in the DP group. A significant decrease in the detrusor pressure was observed at maximum flow rate using PFS in the SP group. Conclusions PUV type 1 encompassed lesions with a spectrum of obstructions ranging from severe to mild, with mild types whose main obstructive lesion existed at the anterior wall of urethra occurring most frequently in boys with refractory daytime urinary incontinence and/or nocturnal enuresis.

  16. New frontiers in urethral reconstruction: injectables and alternative grafts

    PubMed Central

    2015-01-01

    Contemporary management of anterior urethral strictures requires both endoscopic as well as complex substitution urethroplasty, depending on the nature of the urethral stricture. Recent clinical and experimental studies have explored the possibility of augmenting traditional endoscopic urethral stricture management with anti-fibrotic injectable medications. Additionally, although buccal mucosa remains the gold standard graft for substitution urethroplasty, alternative grafts are necessary for reconstructing particularly complex urethral strictures in which there is insufficient buccal mucosa or in cases where it may be contraindicated. This review summarizes the data of the most promising injectable adjuncts to endoscopic stricture management and explores the alternative grafts available for reconstructing the most challenging urethral strictures. Further research is needed to define which injectable medications and alternative grafts may be best suited for urethral reconstruction in the future. PMID:26813260

    Background: The management of posterior urethral valves (PUV) and its sequelae is still a challenge to most pediatric surgeons in our environment due to late presentation and inadequate facilities for long-term evaluation and treatment. Despite initial successful treatment about 40% would develop chronic renal failure. The aim is to describe the presentation, management and outcome of the initial treatment in boys with PUV. Materials and Methods: It is a retrospective analysis of PUV in boys 8 years and below over a 17 years period. Demographic characteristics, clinical features, investigations, and treatment outcome were reviewed. Results: Thirty-seven cases were analyzed. The median age was 5 months (range from birth to 8 years). Three (8.1%) patients had prenatal ultrasound diagnosis. The most common presentation was voiding dysfunction 37 (100%). Part of the preoperative investigation included micturating cystourethrogram (n = 31: 83.8%) and abdomino-pelvic ultrasonography (n = 37:(100%). The mean serum creatinine value of those who presented within the first 30 days of life and those who presented afterwards were 325 (±251) µmol/L and 141 (±100) µmol/L respectively, P = 0.003. Surgical interventions included trans-vesical excision of valves (n = 9: 28.1%), valvotomy (n = 10: 31.3%), balloon avulsion (n = 8: 25.0%), vesicostomy (n = 4: 12.5%) and endoscopic valve avulsion (n = 1: 3.1%). Seventeen (56.7%) patients had serum creatinine >70.4 µmol/L after 1-month of valve excision. Five (13.5%) patients had postrelief complications and 5 (13.5%) died on admission. Ninety percentage (27/30) of patients had poor prognostic indices. Conclusions: The initial treatment outcome was good but most had poor prognostic factors. PMID:26425072

    Objective To describe the emergency and delayed treatment of patients with pelvic fracture urethral injuries (PFUI) presenting to an Italian high-volume centre. Patients and methods In a retrospective, observational study we evaluated the spectrum of PFUI and posterior urethroplasty in an Italian high-volume centre, from 1980 to 2013. Patients requiring emergency treatment for PFUI and delayed treatment for pelvic fracture urethral defects (PFUD) were included. Patients with incomplete clinical records were excluded from the study. Descriptive statistical methods were applied. Results In all, 159 male patients (median age 35 years) were included in the study. A traffic accident was the most frequent (42.8%) cause of PFUI, and accidents at work were reported as the cause of trauma in 34% of patients. Agricultural accidents decreased from 24.4% to 6.2% over the course of the survey. A suprapubic cystostomy was the most frequent (49%) emergency treatment in patients with PFUI. The use of surgical realignment decreased from 31.7% to 6.2%, and endoscopic realignment increased from 9.7% to 35.3%. A bulbo-prostatic anastomosis was the most frequent (62.9%) delayed treatment in patients with PFUD. The use of the Badenoch pull-through decreased from 19.5% to 2.6%, and endoscopic holmium laser urethrotomy increased from 4.9% to 32.7%. Conclusions The spectrum of PFUI and subsequent treatment of PFUD has changed greatly over the last 10 years at our centre. These changes involved patient age, aetiology, emergency and delayed treatments, and were found to be related to changes in the economy and lifestyle of the Italian patients. PMID:26019976

    Sonourethrography (SUG) is an infrequently used modality to observe the male urethra. We modified SUG to examine the reasons for difficulty in urethral catheterization and to determine a safe approach to resolve these problems. Following retrograde urethral jelly injection, modified SUG (mSUG) was performed in male patients with difficulty in urethral catheterization. mSUG was performed using transcutaneous ultrasonography in patients for whom the catheter became lodged in the penile urethra. In other patients, mSUG was performed using transrectal ultrasonography. We divided the causes of difficult indwelling urethral catheterization into physiological and pathological conditions. With regard to physiological conditions, the urethral catheter became stuck in the bulbous portion, membranous urethra, and prostatic urethra. mSUG distinguished the problematic part of the urethra in real time, and it assisted in overcoming the problem. With regard to pathological conditions, urethral stricture after trauma or surgery was clearly demonstrated in the penile and prostatic portions of the urethra. As with physiological conditions, mSUG images assisted in navigating the catheter through the problematic pathological areas or demonstrated the need to abandon the catheterization. mSUG can visualize the male urethra clearly during urethral catheterization and provide real-time assistance with the procedure.

    Surgical management of severe proximal hypospadias or long strictures of the posterior urethra is a difficult clinical task. Often, the therapeutic approach involves the autologous graft of free flaps of bladder or oral mucosa. We recently reported the use of autologous graft of cultured squamous urethral epithelium during urethroplasty in patients with severe proximal hypospadias. The main limitation to the widespread use of cultured epithelium was the long hospitalization due to the requirement of 2 surgical steps. We now report a substantial modification of the surgical procedure which allows for rapid 1-step urethroplasty. Cultured squamous urethral epithelium is tubularized in vitro with the aid of a tubular polytetrafluoroethylene (Gore-Tex) support and 1-step urethroplasty is performed within 30 minutes. Results obtained in 8 patients are presented. PMID:8371392

    Urethral stents were initially developed for the management of urethral strictures and obstructive voiding disorders in select patients. Urethral stent complications are common and may require stent explantation, which is often quite challenging. We present our experience with endoscopic removal of an encrusted UroLume proximal urethral stent in a 72-year-old male using a holmium laser. The literature on various management options and outcomes for urethral stent removal is reviewed. Endoscopic removal of proximal urethral stents is feasible and safe and should be considered as the primary treatment option in patients requiring stent extraction. PMID:23248530

    We report three cases with severe anastomotic strictures, which recurred several times after radical prostatectomy despite repeated treatments of urethral dilation, internal urethrotomy and/or transurethral resection. All three cases were finally treated with holmium laser successfully without any intraoperative or postoperative complications after repeated failures of each treatment. There were two specific characteristics in these three cases: the early onset of the stricture and the pinhole opening located on the top (12-o'clock) of the stricture wall. PMID:15948734

    2002-05-01

    The ability to achieve a long-term, stable, stricture-free, hairless urethral lumen in patients with complex anterior stricture and compromised genital skin is one of the ongoing challenges of reconstructive urologic surgery. The conservative approach by endoscopic urethrotomy or dilatation with a self-catheterization schedule rarely affects a definitive cure except in the short filmy superficial strictures of the bulbous portion of the urethra. Genital fasciocutaneous island flaps are currently the golden standard for definitive, reliable resolution of anterior urethral strictures in patients who have not undergone a prior surgical procedure that may alter the penile or scrotal circulation, or those with skin loss from trauma, decubiti, radiation, or balanitis xerotica obliterans.

    Strictures of vesicourethral anastomosis (VUA), urethral strictures, and bladder neck obliteration are frequent complications occurring after treatment for prostate cancer and dramatically reducing the quality of life of the patients. To date, there is no single standard treatment of urethral strictures. One of the promising methods is laser optical urethrotomy using a solid-state Ho:YAG- laser. Since 2012, we treated 12 patients with strictures of VUA, urethral strictures, and bladder neck obliteration. According urethrography, the maximum length of stricture was 4.5 cm. Treatment efficacy was assessed at 6 months after surgery objectively according urethrography, uroflowmetry, and ultrasound of the bladder with the definition of residual urine; and subjectively--by IPSS questionnaire and QoL questionnaire. After removal of the urethral catheter, all patients had recovered independent urination, decreased IPSS scores by 59.5%, IPSS-QoL score by 45.87%, decreased residual urine volume by 89.92%, and increased maximum urinary flow rate by 78.19%. Intraoperative complications and early postoperative complications were not observed. Ho:YAG laser is a minimally invasive and safe tool for urethrotomy of strictures of VUA, urethral strictures, and bladder neck obliteration arising after treatment for prostate cancer. Definitive conclusions about the effectiveness of this method should be based on long-term results of comparative trials. PMID:25211930

    The authors treated 16 patients presenting with a total of 20 anterior urethral strictures using the KTP 16 Laser. The aetiology was iatrogenic in 50% of cases, infectious in 20% of cases, traumatic in 20% of cases and unknown in 10% of cases. The stricture was situated in the bulbous urethra (80%), membranous urethra (10%) or penil urethra (10%). Laser vaporization of the urethral stricture was performed over the entire circumference of the urethra when necessary, followed by bladder drainage by urethral catheter for 24 hours. All patients were prospectively reviewed at 3 weeks, 3 months and 6 months (clinical symptoms, uroflowmetry, cystourethrography). A complete symptom and urodynamic success was obtained in 13 patients (81%) at 3 and 6 months. The stricture recurred in 4 patients, but only three of them (19%) required treatment (reoperation of repeat dilatations). The mean maximum flow rate increased from 6 mL/s to 20 mL/s at 3 months and was maintained at 19 mL/s at 6 months. No intraoperative or postoperative complications were observed. In conclusion, our results confirm that KTP 532 laser urethral strictures is a reliable and effective method in the medium term. These good results also suggest an advantage in terms of the recurrence rate in comparison with internal urethrotomy. However, our series needs to be evaluated with a longer follow-up and prospective, randomized trials comparing the two methods need to be conducted. PMID:9157820

    Balanitis xerotic obliterans (BXO) is the genital subcategory of lichen sclerosis et atrophicus. The association of BXO with urethral stone causing interruption of the urinary stream and voiding by manual displacement of the urethral stone has not been described before. We describe one such case of a young boy with BXO and urethral stone who voided by manually displacing the stone for over a year. The case is reported to emphasize the ingenuity of the patient in continuing to void for over a year despite the association of the impacted urethral stone with urethral stricture and BXO.

    Over a thirty-month period, a wide variety of common urethral problems were treated on an ambulatory basis, with the neodymium:yttrium-aluminum garnet (Nd:YAG) laser. When used discriminately, laser treatment appears to be an effective modality for the management of selected urethral strictures. Thus far, excellent results have been obtained in 30 of 31 cases of short strictures where laser urethrotomy was performed as the first stricture procedure (average follow-up 10 months). Furthermore, in a series of 36 cases of secondary bladder neck contractures, all of the evaluated patients responded well (average follow-up 7 months). Good results were obtained in only 11 of 48 complicated strictures (average follow-up 14 months). However, while most of these extensive strictures were not eradicated, laser therapy generally produced a documented clinical improvement, comparable to urethrotomy or dilatation, in 15 of these cases. A series of 24 condylomata involving the urethra were treated satisfactorily, with no recurrences (average follow-up 13 months). Laser treatment also has been used successfully for the management of several urethral caruncles, urethral polyps, two meatal hemangiomas, one urethral carcinoma, and a distal duplicated urethra. Recently, the Nd:YAG laser has been applied to the prostatic urethra with vaporization of obstructing median bar hyperplasia. Favorable results have been achieved in 5 of 6 cases treated with a newly developed technique that utilizes direct laser contact. Retrograde ejaculation has not been encountered in these patients (average follow-up 6 months). All of these procedures have been accomplished in the office, largely without urethral catheterization. Lidocaine jelly occasionally supplemented with intravenous sedation provided satisfactory anesthesia. PMID:3400132

    Long-segment urethral stricture or panurethral stricture disease, involving the different anatomic segments of anterior urethra, is a relatively less common lesion of the anterior urethra compared to bulbar stricture. However, it is a particularly difficult surgical challenge for the reconstructive urologist. The etiology varies according to age and geographic location, lichen sclerosus being the most prevalent in some regions of the globe. Other common and significant causes are previous endoscopic urethral manipulations (urethral catheterization, cystourethroscopy, and transurethral resection), previous urethral surgery, trauma, inflammation, and idiopathic. The iatrogenic causes are the most predominant in the Western or industrialized countries, and lichen sclerosus is the most common in India. Several surgical procedures and their modifications, including those performed in one or more stages and with the use of adjunct tissue transfer maneuvers, have been developed and used worldwide, with varying long-term success. A one-stage, minimally invasive technique approached through a single perineal incision has gained widespread popularity for its effectiveness and reproducibility. Nonetheless, for a successful result, the reconstructive urologist should be experienced and familiar with the different treatment modalities currently available and select the best procedure for the individual patient.

    Background Urethral stricture is a common condition, and direct vision internal urethrotomy is prefered as the first treatment option by many urologists, for strictures shorter than 2 cm. This procedure is generally performed under general or spinal anaesthesia. Objectives To investigate the feasibility of adding local urethral anaesthesia to intravenous sedation and analgesia (sedoanalgesia) methods in patients undergoing internal urethrotomy. Patients and Methods A total of 21 and 15 patients with anterior urethral strictures underwent internal urethrotomy under local urethral anaesthesia, with or without sedoanalgesia, respectively. Patient discomfort and pain levels were evaluated using the visual analog scale (VAS). Statistical analyses were calculated with a Mann-Whitney U test to compare difference in VAS scores between the subjects in both groups. Results Two of the 15 (13%) patients operated under local urethral anaesthesia without sedoanalgesia were converted to general anaesthesia due to patient intolerability. Mean pain VAS scores for patients operated under 2% lidocain urethral gel anaesthesia with or without sedoanalgesia were 2.86 cm and 4.5 cm, respectively (P = 0.001). In addition, a VAS score over 3 cm was found in 3 of the 21 (14%) patients with, and 13 of the 15 (86%) patients without sedoanalgesia (P = 0.001). Conclusions The addition of intravenous sedoanalgesia improved the VAS scores of pain and discomfort, compared to patients operated under only local urethral anaesthesia. This may offer patients safer anaesthesia and shorter operative times with equilavent results in selected patients. PMID:23573506

    Rectal stricture formation is a rare complication of aortic aneurysm repair. Two case are described here. A combination of hypotension, a compromised internal iliac circulation and poor collateral supply following inferior mesenteric artery ligation can result in acute ischaemic proctitis--an infrequently described clinical entity. Ulceration and necrosis are the sequelae of prolonged ischaemia and fibrous stricture formation may result. One patient responded to dilatation and posterior mid-rectal myotomy; the other failed to respond to conservative measures and eventually had an end colostomy fashioned following intractable symptoms.

    Background and Objectives: Fossa navicularis strictures following radical prostatectomy are reported infrequently. We recently experienced a series of fossa strictures following robot-assisted laparoscopic radical prostatectomy. Fossa strictures are usually procedure-induced, arising from urethral trauma or infection; catheter size has not been reported as a factor. We describe herein our experience to determine and prevent fossa navicularis stricture development. Methods: From June 2002 until February 2005, 248 patients underwent robot-assisted laparoscopic prostatectomy with the da Vinci surgical system at our institution. Fossa strictures were diagnosed based on acute onset of obstructive voiding symptoms, IPSS and flow pattern changes, and bougie calibration. During our series, we switched from an 18F to a 22F catheter to avoid inadvertent stapling of the urethra when dividing the dorsal venous complex. All patients had an 18F catheter placed after the anastomosis for 1 week. Parameters were evaluated using Fisher's exact test and the Student t test for means. Results: The 18F catheter group (n=117) developed 1 fossa stricture, whereas the 22F catheter group (n=131) developed 9 fossa strictures (P=0.02). The fossa stricture rate in the 18F group was 0.9% versus 6.9% in the 22F group. The 2 groups had no differences in age, body mass index, cardiovascular disease, International Prostate Symptom Score, urinary bother score, SHIM score, preoperative PSA, operative time, estimated blood loss, cautery use, prostate size, or catheterization time. Conclusions: Using a larger urethral catheter size during intraoperative dissection appears to increase the risk 8-fold for fossa stricture as compared with the 18F catheter. The pneumoperitoneum and prolonged extreme Trendelenberg position could potentially contribute to local urethral ischemia. PMID:17931514

    Patients with complications of urethral sling placement for stress urinary incontinence are often treated for recurrent symptoms for years after initial reassuring evaluation. Translabial ultrasound is a noninvasive modality with minimal risks that can clearly diagnose urethral mesh complications. We present a 47-year-old premenopausal woman referred for treatment of urethral stricture and diverticulum 8 years after mesh sling placement. The diagnosis was made at an outside institution by voiding cystourethrogram and cystoscopy. However, translabial ultrasound confirmed the diagnosis of complete urethral transection, and the patient underwent a complex urethral reconstruction. Ultrasound should be used to evaluate patients with a history of urethral sling and persistent lower urinary tract symptoms. Referral to a center with advanced pelvic reconstruction services may be required. PMID:22453271

In this article, we evaluate the progress made in finding a tissue engineered substitute for the human urethra. Researchers have investigated cell-free and cell-seeded grafts. We discuss different approaches to developing these grafts and review their reported successes in human studies. With further work, tissue engineered grafts may facilitate the management of lengthy urethral strictures requiring oral mucosa substitution urethroplasty. PMID:23042444

    Tissue engineering-based urethral replacement holds potential for repairing large segmental urethral defects, which remains a great challenge at present. This study aims to explore the potential of combining biodegradable poly(l-lactide) (PLLA)/poly(ethylene glycol) (PEG) scaffolds and human amniotic mesenchymal cells (hAMSCs) for repairing urethral defects. PLLA/PEG fibrous scaffolds with various PEG fractions were fabricated via electrospinning. The scaffolds were then seeded with hAMSCs prior to implantation in New Zealand male rabbits that had 2.0 cm-long defects in the urethras. The rabbits were randomly divided into three groups. In group A, hAMSCs were grown on PLLA/PEG scaffolds for two days and then implanted to the urethral defects. In group B, only the PLLA/PEG scaffolds were used to rebuild the rabbit urethral defect. In group C, the urethral defect was reconstructed using a regular urethral reparation technique. The repair efficacy was compared among the three groups by examining the urethral morphology, tissue reconstruction, luminal patency, and complication incidence (including calculus formation, urinary fistula, and urethral stricture) using histological evaluation and urethral radiography methods. Findings from this study indicate that hAMSCs-loaded PLLA/PEG scaffolds resulted in the best urethral defect repair in rabbits, which predicts the promising application of a tissue engineering approach for urethral repair.

    2012-01-01

    Introduction The management of an anastomotic stricture after a radical prostatectomy can become a complex and difficult situation when an artificial urinary sphincter precedes the formation of the stricture. The urethral narrowing does not allow the passage of the routinely used urological instruments and no previous reports have suggested alternate approaches. Case presentation We present the case of a 68-year-old Greek man diagnosed as having a recurrent anastomotic stricture approximately two years after a radical prostatectomy and three years after the implantation of an artificial urinary sphincter, and propose novel alternate methods of treatment. Our patient was first subjected to stricture incision with the use of a rigid ureteroscope with a holmium:yttrium-aluminium-garnet laser fiber, which was followed by a second successful attempt with the use of a pediatric resectoscope. After a one-year follow-up, our patient is doing well, with no evidence of recurrence. Conclusions To the best of our knowledge, this is the first report of the management of recurrent urethral strictures following an artificial urinary sphincter implantation. Minimal invasive techniques with the use of small caliber instruments may offer efficient treatment options, diminishing the danger of urethral corrosion. PMID:22472293

    We have investigated the living skin equivalent (LSE) as an alternative source of plastic material for closing full-thickness epithelial-stromal urethral injuries. The possibility of transdifferentiation of epidermal keratinocytes, a component of 3D tissue constructs, was investigated in vivo in a model of the recovery of urethral injuries in laboratory rabbits. Autologous grafting of LSE in de-epithelialized urethra showed that skin keratinocytes placed in a specific in vivo microenvironment can be incorporated into the damaged area and function as urothelium. The use of EGFP transfected keratinocytes allowed us to identify transplanted cells. The reconstructed urethral tubes did not develop strictures or fistulas at the site of the grafted LSE. Immunohistochemical studies of neo-urothelium revealed EGFP-positive cells expressing the urothelial markers K7 and UP3. PMID:25927003

    An all too common cause of urologic consultation is the inability to place a urethral catheter. Often other health care providers have unsuccessfully attempted catheter placement. Urethral false passages, perforations, and edema are common sequelae. Diseases such as urethral strictures, bladder neck contractures, and prostate cancer are often the underlying etiologies for failed catheterization. Traditionally, the use of filiforms and followers or the placement of a suprapubic tube is required to drain the lower urinary tract. Bedside flexible endoscopy was performed in this series not only to define the area and etiology of urethral obstruction, but also to facilitate catheter placement. Fifty-four patients were studied prospectively. Initial endoscopic assessment was based on bedside flexible cystoscopy. Most procedures were performed under topical lidocaine anesthetic. Under direct vision a 0.038 inch standard guide wire was directed through the area or areas of obstruction. Strictures, fibrosis, and false passages were dilated using a series of graduated Nottingham dilators over the guide wire. A Council-tipped urethral catheter was then placed over the guide wire to assure bladder drainage. In 52 of the 54 patients urethral obstructions were dilated and drainage catheters were placed into the bladder. No complications were encountered. This technique is simple, it avoids suprapubic puncture, and it minimizes unneeded trips to the operating room. PMID:8048205

    A steer examined because of obstructive urolithiasis and urethral rupture underwent laser lithotripsy, using a chromium-thulium-holmium:yttrium-aluminum-garnet (Ho:YAG) laser inserted through an ischial urethrotomy. Procedures were performed with caudal epidural anesthesia. Six months after surgery, the urethra was patent with no clinical evidence of urethral stricture or fistula. Ischial urethrotomy provided rapid access to the bladder for catheterization and to the obstructive urolith for lithotripsy. Laser lithotripsy was a rapid and effective means of urolith removal in this steer. PMID:11549094

    Background Techniques to treat urethral stricture and hypospadias are restricted, as substitution of the unhealthy urethra with tissue from other origins (skin, bladder or buccal mucosa) has some limitations. Therefore, alternative sources of tissue for use in urethral reconstructions are considered, such as ex vivo engineered constructs. Purpose To review recent literature on tissue engineering for human urethral reconstruction. Methods A search was made in the PubMed and Embase databases restricted to the last 25 years and the English language. Results A total of 45 articles were selected describing the use of tissue engineering in urethral reconstruction. The results are discussed in four groups: autologous cell cultures, matrices/scaffolds, cell-seeded scaffolds, and clinical results of urethral reconstructions using these materials. Different progenitor cells were used, isolated from either urine or adipose tissue, but slightly better results were obtained with in vitro expansion of urothelial cells from bladder washings, tissue biopsies from the bladder (urothelium) or the oral cavity (buccal mucosa). Compared with a synthetic scaffold, a biological scaffold has the advantage of bioactive extracellular matrix proteins on its surface. When applied clinically, a non-seeded matrix only seems suited for use as an onlay graft. When a tubularized substitution is the aim, a cell-seeded construct seems more beneficial. Conclusions Considerable experience is available with tissue engineering of urethral tissue in vitro, produced with cells of different origin. Clinical and in vivo experiments show promising results.

    The incidence of ureteral strictures has increased worldwide owing to the widespread use of laparoscopic and endourologic procedures. Midureteral strictures can be managed by either an endoscopic approach or surgical reconstruction, including open or minimally invasive (laparoscopic/robotic) techniques. Minimally invasive surgical ureteral reconstruction is gaining in popularity in the management of midureteral strictures. However, only a few studies have been published so far regarding the safety and efficacy of laparoscopic and robotic ureteral reconstruction procedures. Nevertheless, most of the studies have reported at least equivalent outcomes with the open approach. In general, strictures more than 2 cm, injury strictures, and strictures associated either with radiation or with reduced renal function of less than 25% may be managed more appropriately by minimally invasive surgical reconstruction, although the evidence to establish these recommendations is not yet adequate. Defects of 2 to 3 cm in length may be treated with laparoscopic or robot-assisted uretero-ureterostomy, whereas defects of 12 to 15 cm may be managed either via ureteral reimplantation with a Boari flap or via transuretero-ureterostomy in case of low bladder capacity. Cases with more extended defects can be reconstructed with the incorporation of the ileum in ureteral repair. PMID:24466390

    Introduction: We determine the preoperative identifiable risk factors during staging that predict stricture recurrence after urethroplasty. Methods: We conducted a retrospective review of all urethroplasties performed at a Canadian tertiary referral centre from 2003 to 2012. Failure was defined as a recurrent stricture <16 Fr on cystoscopic assessment. Multivariate analysis was calculated by Cox proportional hazard regression. Results: In total, 604 of 651 (93%) urethroplasties performed had adequate data with a mean follow-up of 52 months. Overall urethral patency was 90.7% with failures occurring between 2 weeks and 77 months postoperatively. The average time to recurrence was 11.7 months, with most patients with recurrence within 6 months (42/56; 75%). Multivariate regression identified Lichen sclerosus, iatrogenic, and infectious etiologies to be independently associated with stricture recurrence with hazard ratios (HR) (95% confidence interval) of 5.9 (2.1–16.5; p ≤ 0.001), 3.4 (1.2–10; p = 0.02), and 7.3 (2.3–23.7; p ≤ 0.001), respectively. Strictures ≥5cm recurred significantly more often (13.8% vs. 5.9%) with a HR 2.3 (1.2–4.5; p ≤ 0.01). Comorbidities, smoking, previous urethroplasty, stricture location and an age ≥50 were not associated with recurrence. Conclusion: Urethroplasty in general is an excellent treatment for urethral stricture with patency rates approaching 91%. While recurrences occur over 6 years after surgery, most (75%) recur within the first 6 months. Long segment strictures (≥5 cm), as well as Lichen sclerosus, infectious and iatrogenic etiologies, are associated with increased risk of recurrence. Limitations include the retrospective, single-centre nature of the study and the 7% loss to follow-up due to the centre being a regional referral one. PMID:24940453

    Aims: This is a prospective study of the use and efficacy of a novel technique of circumferential tubularised lingual mucosal graft (LMG) in obliterative and near obliterative bulbar urethral stricture of >2 cm where excisional and augmented anastomotic urethroplasty are not feasible. Materials and Methods: The stenotic urethral segment was opened dorsally in midline and fibrosed urethra was excised taking care to preserve the healthy spongiosum tissue. LMG (av. Length 3 cm) was placed from one end of corporal body towards spongy tissue in a circumferential manner. Another LMG was placed in similar manner to deal with longer stricture. The urethra was tubularised over 14 Fr silicone catheter. Results: A total of 12 men, of mean age 47 years underwent this procedure. The mean follow up period was 11 months starting from July 2014 till manuscript submission. Follow up included voiding cystourethrogram at 3 weeks, cystoscopy at 3 months (one patient didn’t turned up) and subsequent follow up. Mean stricture length was 4.66 cm (range, 3–8.5 cm) and mean operative time was 195 min. (range, 160 to 200 min.). The technique was successful (normal voiding with no need for any post-operative procedure) in 11(91.6%) patients. One patient developed early recurrence at 4 month of surgery and had anastomotic stricture which was successfully managed by direct visual internal urethrotomy. Conclusion: Single stage circumferential tubularised graft urethroplasty is an excellent technique for strictures that include segments of obliterative and near obliterative diseased urethra. It provide a wider neourethra than patch graft urethroplasty. PMID:27141182

    We describe a case of recurrent left-sided epididymitis secondary to severe idiopathic posterior urethritis extending to left seminal vesicle and vas deference with associated urethrovasal reflux (UVR). Cystourethroscopy and micturating cystourethrogram were essential for the diagnosis. Following cystourethroscopy, intravesical, and urethral instillation of topical steroid triamcinolone, patient had a full recovery. Idiopathic urethritis in association with veru montentitis, utriculitis leading to left-sided UVR, inflammation of the seminal vesicle, and vas deference causing secondary epididymitis is rare. We report the first such rare case presenting as recurrent acute scrotum and response to innovative treatment we used. PMID:25755955

    It has long been noticed that women experience direct sexual stimulation from urethral practices that men do not. However, this empirical finding remains to be integrated with the general theory of female psychosexual development. An attempt is made to begin such an integration, with a focus on urethral perversions or perverse trends. PMID:7972586

    Congenital anterior urethral diverticulum (CAUD) may be found all along the anterior urethra and may present itself at any age, from infant to adult. Most children with this condition present with difficulty in initiating micturition, dribbling of urine, poor urinary stream, or urinary tract infection. A careful history will reveal that these children never had a good urinary stream since birth, and the telltale sign is a cystic swelling of the penile urethra. In this paper, we present two cases of CAUD that were managed by excision of the diverticulum with primary repair. PMID:26328174

    Background: Idiopathic urethritis [IU] in children is of unknown etiology and treatment options are limited. We propose a classification for IU based on cystourethroscopy findings and symptoms (Grade 1 – 4) and report our experience with use of topical and oral steroids in IU. Materials and Methods: Retrospective data collection of all male children (0-16 years) diagnosed with IU over a period of 8 years between 2005 and 2012 at our institution. Data was collected on patient demographics, laboratory and radiological investigations, cystourethroscopy findings, management and outcomes. Results: A total of 19 male children were diagnosed with IU. The median age of the patients was 13(7-16) years. Presenting symptoms included dysuria in 12; hematuria in 9; loin pain in 6; and scrotal pain in 2 patients. Both patients with scrotal pain had previous left scrotal exploration that revealed epididymitis. Serum C-reactive protein and Full blood count was tested in 15 patients and was within normal limits in all of them. Cystourethroscopy revealed urethritis of grade-I in 2; grade-II in 11; and grade-III in 3 patients. There were 3 patients with systemic symptoms from extra-urethral extension of inflammation (grade-IV). Mean follow up was 18.9(1-74) months. All patients had steroid instillation at the time of cystourethroscopy. Three patients with IU grade IV required oral steroids (prednisolone) in view of exacerbation of symptoms and signs despite steroid instillation. Complete resolution of symptoms and signs occurred in 18(94.7%) patients. Significant improvement in symptoms and signs was noted in 1(5.3%) patient who is still undergoing treatment. Conclusions: IU in male children can be successfully managed with steroid instillation, especially in grade I and II. Grade III, will need steroid instillation but treatment of scarring and stricture will necessitate longer duration of treatment. In children with IU and extra-urethral symptoms (grade IV), oral steroids may be

    2014-01-01

    Background In patients with pelvic fracture urethral injury there are two options for management: First, to realign as an early primary realignment over a catheter; and second, to place a suprapubic tube with delayed urethroplasty of the inevitable stricture. Methods We reviewed previous reports from 1990 to the present, comparing early endoscopic realignment, early open realignment and suprapubic tube placement, to determine the rates of incontinence, erectile dysfunction and stricture formation. Results Twenty-nine articles were identified. The rates of erectile dysfunction, incontinence, and stricture formation, respectively, were: for early endoscopic realignment, 20.5%, 5.8% and 43.8%; for open realignment over a catheter, 16.7%, 4.7% and 48.9%; and for a suprapubic tube and delayed urethroplasty 13.7%, 5.0%, and 89.0%. A one-way anova showed no difference in the mean rate of erectile dysfunction (P = 0.53) or incontinence (P = 0.73), and only stricture formation was significantly different (P < 0.1). Conclusion The rates of incontinence and erectile dysfunction are similar between the groups. Only the rate of stricture formation was higher in the suprapubic tube and delayed urethroplasty group.

    The author reports his experience and the results of a series of 104 patients suffering from urethral strictures, operated by the same operator from September 1984 to March 1990 and treated by the same surgical method: one stage urethroplasty using a pedicled skin graft. The principles which guided his technique are: complete exposure of the pathological tissue, appropriate size and cut of the graft from a healthy skin zone, careful dissection of the pedicle, elliptical anastomosis at each end and sparing of the corpora cavernosa. Eighty percent of the urethral strictures encountered in the series were complex and situated in various locations: 19 were penile, 55 were bulbar perineal, 30 were bulbar membranous. The urethral strictures were fistulated for 31 cases, multi-operated in 32 case, half of the cases had upstream repercussions from the stenosed zone, and 17 cases had an accompanying pathology. Ninety-one percent of the patients benefited from a patch graft designed to widen the stenosed zone, while a tubular graft was performed for 13 patients to reconstitute a neo-urethra. For a large number of the cases studied, postoperative follow-up was done for two years and for some cases exceeded two years. The operative results were quickly obtained. Good results observed after 3 months generally did not deteriorate thereafter, whereas bad results observed immediately after operation are not definitive since they can be reoperated by the same technique. For 82.7% of the patients, definitive cure was obtained, while 96% of the total number of patients showed considerable improvement. The intermediate results, average (13.6%) and the bad results (3.6%) both show the same inducing factors: past history of localized dilatory manipulations, infected areas but mostly defective application of management techniques. The superiority of this type of surgical technique and its reliability are stressed in the discussion. Also analysed are the following: the difficulty

    We assessed the feasibility, efficacy and long-term results of endoscopic management using Neodymium-YAG (Nd-YAG) laser as a day care procedure in patients with post-traumatic supraprostatic and prostatic strictures. Three patients with post-traumatic prostatic and supraprostatic obliterative strictures underwent Nd-YAG laser core through urethrotomy as a day care procedure. Patient age ranged between 12 and 14 years. Mean duration of injury was 16 months. The length of stricture was assessed by bi-directional endoscopy prior to the procedure in all cases. Core through procedure was carried out using Nd-YAG laser under the guidance of a cystoscope placed antegradely. Patients were discharged on the same day with urethral catheter. Foley catheters were removed at 6 weeks. Nd-YAG laser core through procedure was carried out successfully in all cases with negligible blood loss in a mean time of 48 min. There were no intraoperative or postoperative complications. Patients were discharged on the same day. Follow-up cystogram was conducted at 6 weeks and urethroscopy at months. At a mean follow-up of 23 months, patients were asymptomatic and voiding well. Nd-YAG laser core through urethrotomy is a safe and effective procedure. It is a less invasive alternative to more complex urethroplasty procedures for patients with post-traumatic prostatic and supraprostatic strictures. It can be carried out as a day care procedure in carefully selected patients and has no complications. PMID:12492959

Postcholecystectomy benign biliary strictures are frequently encountered. Endoscopic management of these strictures is challenging. An endoscopic method has been advocated that involves placement of increasing number of stents at regular intervals to resolve the stricture. Malignant hilar strictures are mostly unresectable at the time of diagnosis and only palliation is possible.Endoscopic palliation is preferred over surgery or radiological intervention. Magnetic resonance cholangiopancreaticography is quite important in the management of these strictures. Metal stents are superior to plastic stents. The opinion is divided over the issue of unilateral or bilateral stenting.Minimal contrast or no contrast technique has been advocated during endoscopic retrograde cholangiopancreatography of these patients. The role of intraluminal brachytherapy, intraductal ablation devices, photodynamic therapy, and endoscopic ultrasound still remains to be defined. PMID:26191345

  17. Ruptured urinary bladder attributable to urethral compression by a haematoma after vertebral fracture in a bull

    PubMed Central

    2014-01-01

    Background In male cattle, rupture of the urinary bladder is usually associated with urethral obstruction by uroliths. Less common causes include urethral compression or stricture. This case report describes the findings in a young Limousion breeding bull with rupture of the urinary bladder because of urethral compression by a haematoma after coccygeal fracture. Case presentation The bull had been introduced into a 40-head Red-Holstein herd one week before being injured. One week after introduction to the herd, the bull had an acute onset of anorexia and he was referred to the clinic. There was marked abdominal distension, reduced skin turgor and enophthalmus. The serum concentration of urea and creatinine was increased. Ultrasonographic examination revealed severe ascites and abdominocentesis yielded clear yellow fluid with high urea and creatinine concentrations, which supported a diagnosis of uroperitoneum. The bull was euthanatized because of a poor prognosis. Postmortem examination revealed a comminuted fracture of the first two coccygeal vertebrae associated with a massive haematoma that obstructed entire pelvic cavity. The haematoma compressed the urethra thereby preventing outflow of urine, which resulted in a 5-cm tear ventrally at the neck of the bladder. It was assumed that the newly-introduced bull had sustained the vertebral fractures when he was mounted by a cow. Conclusions The present case study serves to expand the differential diagnosis of urinary bladder rupture. Therefore, in addition to obstructive urolithiasis, compression and stricture of the urethra might be considered in male cattle with uroperitoneum. PMID:24666697

    Purpose: To evaluate the relationship between urinary morbidity after prostate brachytherapy and urethral doses calculated at the base, midprostate, apex, and urogenital diaphragm. Methods and Materials: From February 1998 through July 2002, 186 consecutive patients without a prior history of a transurethral resection underwent monotherapeutic brachytherapy (no supplemental external beam radiation therapy or androgen deprivation therapy) with urethral-sparing techniques (average urethral dose 100%-140% minimum peripheral dose) for clinical T1c-T2b (2002 AJCC) prostate cancer. The median follow-up was 45.5 months. Urinary morbidity was defined by time to International Prostate Symptom Score (IPSS) resolution, maximum increase in IPSS, catheter dependency, and the need for postimplant surgical intervention. An alpha blocker was initiated approximately 2 weeks before implantation and continued at least until the IPSS returned to baseline. Evaluated parameters included overall urethral dose (average and maximum), doses to the base, midprostate, apex, and urogenital diaphragm, patient age, clinical T stage, preimplant IPSS, ultrasound volume, isotope, and D90 and V100/150/200. Results: Of the 186 patients, 176 (94.6%) had the urinary catheter permanently removed on the day of implantation with only 1 patient requiring a urinary catheter >5 days. No patient had a urethral stricture and only 2 patients (1.1%) required a postbrachytherapy transurethral resection of the prostate (TURP). For the entire cohort, IPSS on average peaked 2 weeks after implantation with a mean and median time to IPSS resolution of 14 and 3 weeks, respectively. For the entire cohort, only isotope predicted for IPSS resolution, while neither overall average prostatic urethra nor segmental urethral dose predicted for IPSS resolution. The maximum postimplant IPSS increase was best predicted by preimplant IPSS and the maximum apical urethral dose. Conclusions: With the routine use of prophylactic alpha

    Fifty-seven patients with high peptic stricture and the lower oesophagus lined by columnar epithelium are considered from the clinical point of view. Information from 115 cases of low stricture is introduced for comparison. The average age of adult patients was 62 years with a sex incidence of 36 females to 21 males. There is little difference between the symptoms of high and low strictures. Radiologically, the majority of high strictures are short and smooth but other types are illustrated. Carcinoma and congenital mid-oesophageal web are considered in the differential diagnosis. There was an associated duodenal ulcer in 10% of cases. In six patients, a high stricture developed soon after an abdominal operation or period of recumbency. Two patients are illustrated showing the process of stricture formation. Four patients are described who had gastric-lined oesophagus but no ulceration of stricture. One patient had a Barrett ulcer in addition to a high stricture. A patient is described in whom the mucosa of the lower oesophagus appeared to be replaced by jejunal mucosa following oesophagojejunostomy. One patient is illustrated in whom a stricture was seen to ascend the oesophagus over a period of six years. Thirty-three patients were treated by dilatation and 24 by operation. Hernial repair is an effective form of treatment. Of 19 patients treated in this way, significant dysphagia persisted in two and slight dysphagia in one. The clinical findings are discussed in relation to the origin of columnar epithelium in the oesophagus. PMID:1257929

    Purpose: Anterior urethral valves (AUVs) is an unusual cause of congenital obstruction of the male urethra, being 15–30 times less common than posterior urethral valves (PUVs). It has been suggested that patients with congenital anterior urethral obstruction have a better prognosis than those with PUV, with less hydronephrosis, and a lower incidence of chronic renal insufficiency (5 vs. 30%). The long-term prognosis of AUVs is not clear in the literature. In this report we describe our experience and long-term follow up of patients with anterior urethral valve. Materials and Methods: We retrospectively identified 13 patients who presented with the diagnosis of AUVs in our institutions between January 1994 and June 2012. Two patients were excluded: one patient had no follow up after intervention; the other had a follow up <1 year. From the 11 patients included, we evaluated the gestational age, prenatal and postnatal ultrasound findings, voiding cystourethrogram findings, age upon valve ablation, micturition pattern, creatinine, and clinical follow up. Results: Between 1994 and 2012 we evaluated 150 patients with the diagnosis of urethral valves. Of this group, 11 patients (7.3%) had AUVs and an adequate follow up. Mean follow up is 6.3 years (2.5–12 years). Five (45.4%) patients had prenatal diagnosis of AUV. The most common prenatal ultrasonographic finding was bilateral hydronephrosis and distended bladder. One patient showed a large perineal cystic mass, which was confirmed to be a dilated anterior urethra. The mean gestational age was 37.6 weeks (27–40 WGA). Postnatally, 90% had trabeculated bladder, 80% hydronephrosis, and 40% renal dysplasia. The most common clinical presentation was urinary tract infection in five patients (45.4%), followed by weak urinary stream found in four patients (36.3%). The age at initial surgical intervention ranged between 7 days and 13 years. Seven (63.6%) patients had primary transurethral valve resection or

    Summary Background Urethral valves are infravesical congenital anomalies, with the posterior urethral valve (PUV) being the most prevalent one. Anterior urethral valve (AUV) is a rare but a well-known congenital anomaly. AUV and diverticula can cause severe obstruction, whose repercussions on the proximal urinary system can be important. Few cases have been described; both separately and in association with urethral diverticulum. The presentation of such a rare but important case led us to a report with highlighting its classic imaging features. Case Report We present a case report of AUV with lower urinary tract symptoms in a 6-year-old boy with complaints of a poor stream of urine and strain to void. Unique findings were seen on Retrograde Urethrography (RGU) and Voiding Cysto-Urethrography (VCUG), i.e. linear incomplete filling defect in the penile urethra and associated mild dilatation of the anterior urethra ending in a smooth bulge. On cysto-urethroscopy the anterior urethral valve was confirmed and fulguration was done. Conclusions Congenital anterior urethral valve is an uncommon but important cause of infravesical lower urinary tract obstruction that is more common in male urethra. It can occur as an isolated AUV or in association with diverticulum and VATER anomalies. Early diagnosis and management of this rare condition is very important to prevent further damage, infection and vesicoureteral reflux. AUV may be associated with other congenital anomalies of the urinary system; therefore a full evaluation of the urinary system is essential. PMID:27231492

  4. Management of Biliary Strictures After Liver Transplantation

    PubMed Central

    Villa, Nicolas A.

    2015-01-01

    Strictures of the bile duct are a well-recognized complication of liver transplant and account for more than 50% of all biliary complications after deceased donor liver transplant and living donor liver transplant. Biliary strictures that develop after transplant are classified as anastomotic strictures or nonanastomotic strictures, depending on their location in the bile duct. The incidence, etiology, natural history, and response to therapy of the 2 types vary greatly, so their distinction is clinically important. The imaging modality of choice for the diagnosis of biliary strictures is magnetic resonance cholangiopancreatography because of its high rate of diagnostic accuracy and limited risk of complications. Biliary strictures that develop after liver transplant may be managed with endoscopic retrograde cholangiography (ERC), percutaneous transhepatic cholangiography (PTC), or surgical revision, including retransplant. The initial treatment of choice for these strictures is ERC with progressive balloon dilation and the placement of increasing numbers of plastic stents. PTC and surgery are generally reserved for failures of endoscopic therapy or for anatomic variants that are not suitable for ERC. In this article, we discuss the classification of biliary strictures, their diagnosis, and the therapeutic strategies that can be used to manage these common complications of liver transplant.

    Introduction: The correction of fossa navicularis strictures poses a distinct reconstructive challenge as it requires attention to cosmesis, in addition to urethral patency. Different graft and flap based repairs have been described with variable success rates. However, the ideal management remains unclear. The feasibility and efficacy of a single stage ventral onlay buccal mucosa graft urethroplasty (VOBMGU) for navicular fossa strictures (NFS) was evaluated in the present study. Subjects and Methods: All patients with NFS attending urology out-patient department from March, 2009 onward accepting VOBMGU were evaluated prospectively. Patients with minimum 1 year of follow-up were included for analysis. The technique involves opening the diseased stenosed meatus ventrally up to the corona. The diseased mucosa is excised leaving a midline strip of native urethral mucosa on the dorsal side. The buccal mucosal graft (BMG) is fixed on either side of this strip over a 24 Fr. silicone catheter. The glans wings are apposed in midline taking anchoring bites on the mucosal graft ventrally. Post-operatively patients were reviewed at 1, 3, 6 and 12 months and annually thereafter. Cosmetic acceptance and splaying of the urinary stream was assessed with individual questionnaires. Results: A total of six patients underwent VOBMGU. Average flow rate at 3 months post-operatively was 12 ml/s. The end result was cosmetically highly acceptable. There was no fistula in any of the cases. With a median follow-up of 37 months, only one patient had a recurrence of stricture in a proximal site. Conclusions: VOBMGU is a viable technique for reconstruction of NFS with promising short term results. However, long-term follow-up is necessary. PMID:24497676

    Background The treatment options for patients requiring repair of a long segment of the urethra are limited by the availability of autologous tissues. We previously reported that acellular collagen-based tubularized constructs seeded with cells are able to repair small urethral defects in a rabbit model. Objective We explored the feasibility of engineering clinically relevant long urethras for surgical reconstruction in a canine preclinical model. Design, setting, and participants Autologous bladder epithelial and smooth muscle cells from 15 male dogs were grown and seeded onto preconfigured collagen-based tubular matrices (6 cm in length). The perineal urethral segment was removed in 21 male dogs. Urethroplasties were performed with tubularized collagen scaffolds seeded with cells in 15 animals. Tubularized constructs without cells were implanted in six animals. Serial urethrography and three-dimensional computed tomography (CT) scans were performed pre- and postoperatively at 1, 3, 6, and 12 mo. The animals were euthanized at their predetermined time points (three animals at 1 mo, and four at 3, 6, and 12 mo) for analyses. Outcome measurements and statistical analysis Statistical analysis of CT imaging and histology was not needed. Results and limitations CT urethrograms showed wide-caliber urethras without strictures in animals implanted with cell-seeded matrices. The urethral segments replaced with acellular scaffolds collapsed. Gross examination of the urethral implants seeded with cells showed normal-appearing tissue without evidence of fibrosis. Histologically, an epithelial cell layer surrounded by muscle fiber bundles was observed on the cell-seeded constructs, and cellular organization increased over time. The epithelial and smooth muscle phenotypes were confirmed using antibodies to pancytokeratins AE1/AE3 and smooth muscle–specific desmin. Formation of an epithelial cell layer occurred in the unseeded constructs, but few muscle fibers formed

    Benign biliary strictures are most commonly a consequence of injury at laparoscopic cholecystectomy or fibrosis after biliary-enteric anastomosis. These strictures are notoriously difficult to treat and traditionally are managed by resection and fashioning of acholedocho- or hepato-jejunostomy. Promising results are being achieved with newer minimally invasive techniques using endoscopic or percutaneous dilatation and/or stenting and these are likely to play an increasing role in the management. Even low-grade biliary obstruction carries the risks of stone formation, ascending cholangitis and hepatic cirrhosis and it is important to identify and treat this group of patients. There is currently no consensus on which patient should have what type of procedure, and the full range of techniques may not be available in all hospitals. Careful assessment of the risks and likely benefits have to be made on an individual basis. This article reviews the current literature and discusses the options available. The techniques of endoscopic and percutaneous dilatation and stenting are described with evaluation of the likely success and complication rates and compared to the gold standard of biliary-enteric anastomosis.

    The clinical diagnosis, ultrasonographic findings, surgical management, outcome, and survival rate of perineal or prescrotal urethral dilatation in 12 male calves are described. All calves were crossbred and intact males. The most noticeable clinical presentations were perineal (n= 10) or prescrotal (n= 2) swellings and micturition problems. The main ultrasonographic findings were oval shaped dilatation of the urethra in all animals with dimensions of 40-75 X 30-62 mm. The calves with perineal urethral dilatation were treated by perineal urethrostomy (n= 4) and partial penile transection including the dilated urethra and urethral fistulation (n= 6). Prescrotal urethral dilatations were treated by penile transection proximal to the dilatation site (n= 2). Cystitis and stricture of the urethra were recorded postoperatively for two of the calves that underwent perineal urethrostomy. Nine animals were slaughtered at normal body weight approximately 6-8 months after the surgical treatment. Three animals were slaughtered after approximately three to four months, two of them having gained insufficient body weight. Our study shows that ultrasonography is a useful tool for the diagnosis of urethral dilatation in bovine calves. Our study also shows that the partial penile transection may be a suitable and satisfactory choice of surgical treatment for correcting the urethral dilatation in bovine calves. PMID:26623322

    Stricture formation is a common complication of Crohn’s disease, occurring in approximately one third of all patients with this condition. While the traditional management of such strictures has been largely surgical, there have been case series going back three decades highlighting the potential role of endoscopic balloon dilation in this clinical setting. This review article summarizes the stricture pathogenesis, focusing on known clinical and genetic risk factors. It then highlights the endoscopic balloon dilation research to date, with particular emphasis on three large recent case series. It concludes by describing the literature consensus regarding specific methodology and presenting avenues for future investigations. PMID:23189221

    Benign biliary strictures are a common indication for endoscopic retrograde cholangiopancreatography (ERCP). Endoscopic management has evolved over the last 2 decades as the current standard of care. The most common etiologies of strictures encountered are following surgery and those related to chronic pancreatitis. High-quality cross-sectional imaging provides a road map for endoscopic management. Currently, sequential placement of multiple plastic biliary stents represents the preferred approach. There is an increasing role for the treatment of these strictures using covered metal stents, but due to conflicting reports of efficacies as well as cost and complications, this approach should only be entertained following careful consideration. Optimal management of strictures is best achieved using a team approach with the surgeon and interventional radiologist playing an important role. PMID:25613176

    There is an established association between ED and pelvic fracture urethral injuries (PFUIs). However, ED can occur after the injury and/or the urethral repair. To our knowledge, only one study of erectile function (EF) after urethroplasty for PFUIs used a validated questionnaire. This study was carried out to determine the impact of anastomotic posterior urethroplasty for PFUIs on EF. We retrospectively reviewed the computerized surgical records to identify patients who underwent anastomotic urethroplasty for PFUIs from 1998 to 2014. Those patients were contacted by phone or mail and were re-evaluated in the outpatient clinic by International Index of Erectile Function questionnaire; in unmarried men, the single-question self-report of ED was used for evaluation of EF, clinical examination and penile color Doppler ultrasonography (CDU) for men with ED. Overall, 58 patients were included in the study among whom 36 (62%) men were sexually active and the remaining 22 (38%) were single. The incidence of ED among our group is 72%. All patients developed ED after initial pelvic trauma and none of our patients had impaired EF after urethroplasty. The incidence of ED increased proportionally with severity of pelvic trauma. All patients with type-C pelvic fracture, associated symphysis pubis diastasis, sacroiliac joints diastasis and bilateral pubic ramus fractures had ED. Men with PFUIs had worse EF than men in other series with pelvic fractures without urethral injury. The majority (88%) of men with ED showed veno-occlusive dysfunction on penile CDU. So we concluded that men with PFUIs had a high incidence of ED up to 72%. Anastomotic posterior urethroplasty had no negative impact on EF and the development of ED after PFUIs was related to the severity of the original pelvic trauma. Veno-occlusive dysfunction is the commonest etiology of ED on penile CDU. PMID:27146349

    The standard of care after a pelvic fracture urethral injury is a repair via a one-stage anastomotic posterior urethroplasty using a step-wise perineal approach. The initial injury, immediate postoperative management, and surgical repair can all affect urinary continence in these patients. Proximal continence mechanisms, particularly the bladder neck, are particularly important in maintaining urinary continence in these patients. Patients with bladder neck dysfunction should be counselled about the greater risk of urinary incontinence. PMID:26019981

    Although the most common cause of cholecystitis is gallstones, other conditions may present as acute cholecystitis. We describe a case of eosinophilic cholecystitis with common bile duct stricture. A 36-year-old woman initially had generalised abdominal pain and peripheral eosinophilia. Diagnostic laparoscopy showed eosinophilic ascites and necrotic nodules on the posterior abdominal wall. She was treated with anthelminthics on presumption of toxacara infection based on borderline positivity of serological tests. She later presented with acute cholecystitis and had a cholecystectomy and choledocotomy. Day 9 T-tube cholangiogram showed irregular narrowing of the distal common bile duct. The patient's symptoms were improved with steroids and the T-tube was subsequently removed. PMID:27222280

    Objective To determine the incidence, mechanism of injury, wounding pattern and surgical management of urethral and penile injuries sustained in civil violence during the Iraq war. Patients and methods In all, 2800 casualties with penetrating trauma to the abdomen and pelvis were received at the Al-Yarmouk Hospital, Baghdad, from January 2004 to June 2008. Of these casualties 504 (18%) had genitourinary trauma, including 45 (8.9%) with urethral and/or penile injuries. Results Of 45 patients, 29 (64%) were civilians and 16 (36%) were Iraqi military personnel. The injury was caused by an improvised explosive device (IED) in 25 (56%) patients and by individual firearms in 20 (44%). Of the patients, 24 had penile injuries, 15 had an injury to the bulbar urethra and six had an injury to the posterior urethra. Anterior urethral injuries were managed by primary repair, while posterior urethral injuries were managed by primary realignment in five patients and by a suprapubic cystostomy alone in one. An associated injury to major blood vessels was the cause of death in eight of nine patients who died soon after surgery (P < 0.001). Conclusion Urethral and penile injuries were caused by IEDs and individual firearms with a similar frequency. Most of the casualties were civilians and a minority were military personnel. Injuries to the anterior urethra can be managed by primary repair, while injuries to the posterior urethra can be managed by primary realignment. An associated trauma to major blood vessels was the leading cause of death in these casualties. PMID:26019940

    Purpose: To describe a new technique for staged hypospadias repair in which the urethral plate is divided and tubularized transverse island flap prefabricated partial distal urethral at the time of the first stage. Materials and methods: Sixteen patients with proximal hypospadias associated with severe chordee were operated on using a new staged technique. At the time of the first stage, the urethral plate was divided and chordee was corrected. Then tubularized transverse island flap was used to prefabricate partial distal urethra. The defective urethra was repaired using the Thiersch-Duplay principle at the second stage. Results: All participants have completed both stages of the operation. The mean follow-up duration was 18.4 months (range from 6 to 72 months). In the first-stage surgery, the modified tabularized transverse preputial island flap was performed on 6 patients, whereas the modified preputial double-faced island flap was performed on the other 10 patients. All of the prefabricated partial distal neourethras had no evidence of stenosis or scarring. The result of the second-stage procedure was a complete penis with integrated urethral. All patients were satisfied with cosmetic and functional results. Neither stricture nor diverticula was observed. A good urinary stream during the urination was attained in 12 (75.0%) patients. Four cases (25.0%) developed urethrocutaneous fistula after the second stage repair. Conclusions: In our preliminary series, this procedure improved functional and cosmetic results. It may be applicable to most cases of proximal hypospadias. Even when complications occur, they are less severe compared to those of the traditional staged approach. PMID:25932188

    Urethral erosions have been reported with various sling materials placed by means of various techniques. The patient often presents in the immediate postoperative period, although late presentations have been described. The diagnosis is made on cystoscopy, and mesh excision with urethral reconstruction is advocated. We present the cases of two patients with urethral erosion after mid-urethral polypropylene sling who presented 3 months after surgery with urethral pain, mid-urethral blockage and symptoms of bladder dysfunction. Urethroscopy revealed the mesh bridging the lumen of the urethra. Trans-vaginal mesh excision and layered urethral reconstruction was curative in both patients. PMID:16741603

    Endoscopic radiofrequency ablation (RFA) is a novel palliation therapy for malignant biliary stricture; however, its feasibility and safety has not yet been clearly defined. The aim of the present study was to evaluate the feasibility and safety of endoscopic RFA for the treatment of malignant biliary strictures. A total of 12 patients treated by endoscopic RFA between December 2011 and October 2013 were retrospectively analyzed. Adverse events within 30 days post-intervention, stricture diameters prior to and following RFA, stent patency and survival time were investigated. A total of 12 patients underwent 20 RFA procedures as a treatment for malignant biliary strictures. Two patients required repeated elective RFA (4 and 6 times, respectively). All 20 RFA procedures were successfully performed without technical problems. During a 30 day period following each RFA procedure, two patients experienced fever (38.2 and 38.9°C, respectively) and another patient exhibited post-endoscopic retrograde cholangiopancreatography pancreatitis. The 30- and 90-day mortality rates were 0 and 8.3%, respectively. Mean stricture diameter prior to RFA was 5.3 mm (standard deviation (SD), 0.9 mm; range, 5–8 mm), and the mean diameter following RFA was 12.6 mm (SD, 3.1 mm; range, 8–15 mm). There was a significant increase of 7.3 mm in the bile duct diameter following RFA in comparison with prior to RFA (t=8.6; P≤0.001). Of the 11 patients with stents inserted following RFA, the median stent patency was 125.0 days [95% confidence interval (CI), 94.7–155.3 days]. Extrapolated median survival following the first RFA was 232 days (95% CI, 94.3–369.7 days). In conclusion, RFA appears to be an efficient and safe treatment strategy for the palliation of unresectable malignant biliary strictures. PMID:27284336

  1. Benign Biliary Strictures: Diagnostic Evaluation and Approaches to Percutaneous Treatment.

    PubMed

    Fidelman, Nicholas

    2015-12-01

    Interventional radiologists are often consulted to help identify and treat biliary strictures that can result from a variety of benign etiologies. Mainstays of noninvasive imaging for benign biliary strictures include ultrasound, contrast-enhanced computed tomography and magnetic resonance imaging, magnetic resonance cholangiopancreatography, and computed tomography cholangiography. Endoscopic retrograde cholangiography is the invasive diagnostic procedure of choice, allowing both localization of a stricture and treatment. Percutaneous biliary interventions are reserved for patients who are not candidates for endoscopic retrograde cholangiography (eg, history of distal gastrectomy and biliary-enteric anastomosis to a jejunal roux limb). This review discusses the roles of percutaneous transhepatic cholangiography and biliary drainage in the diagnosis of benign biliary strictures. The methodology for crossing benign biliary strictures, approaches to balloon dilation, management of recalcitrant strictures (ie, large-bore biliary catheters and retrievable covered stents), and the expected outcomes and complications of percutaneous treatment of benign biliary strictures are also addressed.

    2015-01-01

    Urethral diverticulum (UD) is a condition in which a variably sized outpouching forms, next to the urethra. Because it connects to the urethra, this outpouching repeatedly gets filled with urine during micturition, thus causing symptoms. In females, it presents as a bulge in anterior vagina, mimicking a vaginal wall cyst. Various aetiologies proposed attributing to urethral diverticulum formation is repeated infection of the periurethral gland, childbirth trauma, iatrogenic and urethral instrumentation. Patients of UD present with non specific irritative lower urinary tract symptoms such as increased frequency, urgency and dysuria; symptoms may not correlate with the size of the diverticulum. Recurrent cystitis or urinary tract infection is seen in one-third of patients. Pain, hematuria, post-void dribbling, dyspareunia, urinary retention or incontinence is other symptoms. In some cases, there may be associated urethral calculi or carcinoma. Magnetic resonance imaging (MRI) is highly sensitive and specific for the diagnosis of UD, although non invasive sonography may be the first line investigation. Treatment is by transvaginal diverticulectomy or marsupialization. A 60-year-old P9L6 postmenopausal lady, presented with a tender, hard suburethral anterior vaginal wall mass. Cystourethroscopy revealed a small opening in posterior urethra, with stone visible through it. With the final diagnosis of suburethral diverticulum with retained multiple calculi, excision of the diverticulum and repair of urethra was done vaginally. Correct evaluation and treatment of this condition can lead to avoidance of urinary tract injury. PMID:26557574

  4. Bladder neck incompetence at posterior urethroplasty

    2015-01-01

    The finding of an incompetent bladder neck (BN) at the time of posterior urethroplasty will necessarily exacerbate the already difficult situation. In such cases the aim of the treatment is not only to restore urethral continuity by end-to-end urethral anastomosis, but also to restore the function of the BN to maintain urinary continence. Fortunately, the incidence of incompetence of the BN at posterior urethroplasty is uncommon, usually ≈4.5%. It seems that pelvic fracture-related BN injuries, in contrast to urethral injuries which result from a shearing force, are due to direct injury by the sharp edge of the fractured and displaced pubic bone. The risk of injuries to the BN is greater in children, in patients with a fracture involving both superior and inferior pubic rami on the same side, and in those managed initially by primary realignment. An incompetent BN is suspected by finding an open rectangular BN on cystography, and a fixedly open BN on suprapubic cystoscopy. An incompetent BN can be treated either subsequent to or concomitant with the urethral repair, according to whether a perineal or a perineo-abdominal urethroplasty is used, respectively. Several options have been reported to treat pelvic fracture-related BN incompetence, including reconstructing the BN, forming a new sphincter by tubularisation of a rectangular flap of the anterior bladder wall, and mechanical occlusion by an artificial sphincter or collagen injection. Reconstruction of the BN by the Young-Dees-Leadbetter∗∗ procedure probably provides the most successful results. PMID:26019982

  5. A Giant Dumbbell Shaped Vesico-Prostatic Urethral Calculus: A Case Report and Review of Literature

    PubMed Central

    Prabhuswamy, Vinod Kumar; Tiwari, Rahul; Krishnamoorthy, Ramakrishnan

    2013-01-01

    Calculi in the urethra are an uncommon entity. Giant calculi in prostatic urethra are extremely rare. The decision about treatment strategy of calculi depends upon the size, shape, and position of the calculus and the status of the urethra. If the stone is large and immovable, it may be extracted via the perineal or the suprapubic approach. In most of the previous reported cases, giant calculi were extracted via the transvesical approach and external urethrotomy. A 38-year-old male patient presented with complaints of lower urinary tract symptoms. Further investigations showed a giant urethral calculus secondary to stricture of bulbo-membranous part of the urethra. Surgical removal of calculus was done via transvesical approach. Two calculi were found and extracted. One was a huge dumbbell calculus and the other was a smaller round calculus. This case was reported because of the rare size and the dumbbell nature of the stone. Giant urethral calculi are better managed by open surgery. PMID:23762742

    Urethral caruncle is a benign polypoid mass of the urethral meatus in primarily postmenopausal women. Although a conclusive association with malignancy, urologic disorder, or systemic disease has not been established, often the lesion carries a challenging clinical differential diagnosis that includes malignancy. Conversely, unexpected malignancy is identified in some cases resembling caruncle clinically. We examined clinical and histopathologic characteristics in 41 patients. Medical records were assessed for presentation, clinical diagnosis, associated urothelial carcinoma, radiation treatment, tobacco use, immunologic/urologic disorder, and treatment strategy/outcome. Average patient age was 68 years (range, 28-87 years). Presenting symptoms were pain (37%), hematuria (27%), and dysuria (20%), in contrast to asymptomatic (32%). Clinical diagnosis favored malignancy in 10% of cases. Concurrent or subsequent urothelial carcinoma was present for 5 patients (12%), although none developed urethral carcinoma. Histologic features included mixed hyperplastic urothelial and squamous lining, overlying a variably fibrotic, edematous, inflamed, and vascular stroma. Invaginations of urothelium extending into the stroma were common (68%), showing rounded nests with cystic or glandular luminal spaces, similar to urethritis cystica/glandularis, without intestinal metaplasia. Two lesions included an organizing thrombus, 1 with intravascular papillary endothelial hyperplasia. Twenty patients were treated with topical medications without resolution. Three lesions recurred (7%) after excision. A subset of patients had history of smoking or previous pelvic irradiation. Urethral caruncle is an uncommon lesion that may clinically mimic benign and malignant conditions. Awareness of the spectrum of clinical and histologic differential diagnoses is important in dealing with this unusual disease. PMID:22397870

    Objectives The objective of this study was to define anatomical and radiological features of the so-called Y-type urethral duplication. Methods The study included four male patients and one female patient with congenital connection between the urogenital tract and the external anal orifice. Investigations included renal sonography, urethrograms, and magnetic resonance imaging pelvis in the last patient. The urethrograms of male patients were carefully reviewed, in addition to available urethrograms of similar cases that could be obtained through searching the literature. Results Unlike cases of urethral duplication, the male patients had always a complete prepuce and a functioning anterior urethra in 25%. The accessory uroanal channel had almost always a constant origin from the posterior urethra. Some tension seems to be exerted by the urethroanal tract pulling on and causing a kink in the posterior urethra. Management was simple in patients without anterior urethral hypoplasia (one male and the female patient). Both were treated by simple excision of the communicating ano-urogenital tract through a perineal approach with an excellent outcome. Histopathological examination of excised tracts revealed stratified squamous cell in the former and transitional cell lining in the latter. In patients with hypoplastic anterior urethra, staged urethral reconstruction was performed in two, and progressive dilatation of hypoplastic anterior urethra was tried in the last patient. Conclusion Several observations would support diagnosing the congenital connection between the urinary tract and the external anal orifice in the male as a congenital fistula rather than an accessory urethra. Confirming and accepting this information may have its impact on changing the current surgical approach. PMID:26024207

    2016-01-01

    Biliary complications are common after living donor liver transplant (LDLT) although with advancements in surgical understanding and techniques, the incidence is decreasing. Biliary strictures are more common than leaks. Endoscopic retrograde cholangiopancreatography (ERCP) is the first line modality of treatment of post LDLT biliary strictures with a technical success rate of 75%-80%. Most of ERCP failures are successfully treated by percutaneous transhepatic biliary drainage (PTBD) and rendezvous technique. A minority of patients may require surgical correction. ERCP for these strictures is technically more challenging than routine as well post deceased donor strictures. Biliary strictures may increase the morbidity of a liver transplant recipient, but the mortality is similar to those with or without strictures. Post transplant strictures are short segment and soft, requiring only a few session of ERCP before complete dilatation. Long-term outcome of patients with biliary stricture is similar to those without stricture. With the introduction of new generation cholangioscopes, ERCP success rate may increase, obviating the need for PTBD and surgery in these patients. PMID:27057304

  14. Management of benign biliary strictures: current status and perspective.

    2015-09-01

    Benign biliary strictures are common and occur either from hepato-biliary surgery or from diseases including chronic pancreatitis and primary sclerosing cholangitis, among others. The treatment of many such strictures is endoscopic with evolving new approaches especially with fully covered metal stents. The only classification system available is for postoperative strictures with the intention to guide surgical correction. There is no useful classification system to guide both assessment and management of benign biliary strictures. This proposed classification is relevant to patient care in assisting diagnosis and endoscopic management. PMID:26147976

    The limited amount of available epithelial tissue is considered a main cause of the high rate of urethral reconstruction failures. The aim of this study was to investigate whether epithelial-differentiated rabbit adipose-derived stem cells (Epith-rASCs) could play a role of epithelium in vivo functionally and be a potential substitute of urothelium. Substitution urethroplasty was performed to repair an anterior urethral defect in male New Zealand rabbits using Epith-rASCs seeded bladder acellular matrix grafts (BAMGs) after 5-bromo-2'-deoxyuridine (BrdU) labeling, based on the in vitro epithelial induction system we previously described. Urethroplasty with cell-free BAMGs and with undifferentiated rASCs (Und-rASCs) seeded BAMGs were performed as controls. After surgery, a notable amelioration of graft contracture and recovery of urethral continuity were observed in the Epith-rASCs/BAMG group by retrograde urethrograms and macroscopic inspection. Immunofluorescence revealed that the BrdU-labeled Epith-rASCs/Und-rASCs colocalized with cytokeratin 13 or myosin. Consistent with the results of western blotting, at early postimplantation stage, the continuous epithelial layer with local multilayered structure was observed in the Epith-rASCs/BAMG group, whereas no significant growth and local monolayer growth profile of epithelial cells were observed in the BAMG and Und-rASCs/BAMG group, respectively. The results showed that Epith-rASCs could serve as a potential substitute of urothelium for urethral tissue engineering and be available to prevent lumen contracture and subsequent complications including recurrent stricture.

    Background: Although steroid injection prevents stricture after esophageal endoscopic submucosal dissection (ESD), some patients require repeated sessions of endoscopic balloon dilation (EBD). We investigated the risk for refractory stricture despite the administration of steroid injections to prevent stricture in patients undergoing esophageal ESD. Refractory stricture was defined as the requirement for more than three sessions of EBD to resolve the stricture. In addition, the safety of steroid injections was assessed based on the rate of complications. Patients and methods: We analyzed data from 127 consecutive patients who underwent esophageal ESD and had mucosal defects with a circumferential extent greater than three-quarters of the esophagus. To prevent stricture, steroid injection was performed. EBD was performed whenever a patient had symptoms of dysphagia. Results: The percentage of patients with a tumor circumferential extent greater than 75 % was significantly higher in those with refractory stricture than in those without stricture (P = 0.001). Multivariate analysis adjusted for age, sex, history of radiation therapy, tumor location, and tumor diameter showed that a tumor circumferential extent greater than 75 % was an independent risk factor for refractory stricture (adjusted odds ratio [OR] 5.49 [95 %CI 1.91 – 15.84], P = 0.002). Major adverse events occurred in 3 patients (2.4 %): perforation during EBD in 2 patients and delayed perforation after EBD in 1 patient. The patient with delayed perforation underwent esophagectomy because of mediastinitis. Conclusions: A tumor circumferential extent greater than 75 % is an independent risk factor for refractory stricture despite steroid injections. The development of more extensive interventions is warranted to prevent refractory stricture. PMID:27004256

    2008-01-01

    Purpose Recognition the urethral plate comprises tissues that normally should have created the urethra was an important milestone in hypospadias surgery, giving rise to new operative repairs - most notably the tubularized incised plate technique. This article reviews the current state of the art for hypospadias repair using tubularized, incised plate (TIP). Materials and Methods Personal experience and literature reports were reviewed to summarize use of TIP urethroplasty for distal, proximal, and re-operative hypospadias repairs. Results The TIP can be used to correct all distal and most proximal hypospadias. The major contraindication is ventral curvature that leads to urethral plate transection for straightening, which is only necessary in some proximal cases. Reoperations can also be performed using TIP provided the urethral plate has been maintained and is not grossly scarred. Complication rates are comparable to previously used techniques, while cosmetic appearance after TIP is considered superior to other available procedures. Conclusions Recognition of the urethral plate and its incorporation into the neourethra has revolutionized hypospadias repair. The most commonly used operative procedure today is TIP. PMID:19468397

    Purpose. Although most urethral diverticula in women are benign, there is a subset of patients who develop malignant changes. Limited studies report the pathologic findings associated with this relatively rare entity. We describe the clinicopathologic findings of women who underwent urethral diverticulectomy. Methods. A consecutive series of 29 women who underwent surgical resection of a urethral diverticulum were identified between 1992 and 2013. Clinical and radiographic data was collected by retrospective review of patient medical records. All pathological slides were rereviewed by a single urologic pathologist. Results. Of the 14 women with clinical data, 9 (64%) presented with urgency, 7 (50%) with urinary frequency, 3 (21%) with urinary incontinence, and 3 (21%) with dysuria. Mean diverticular size was 2.3 (±1.4) cm. Although one patient (3%) had invasive adenocarcinoma on final pathology, the remaining 28 cases (97%) demonstrated benign features. The most common findings were inflammation (55%) and nephrogenic adenoma (21%). Conclusions. Although most urethral diverticula in women are benign, there is a subset of patients who develop malignancy in association with the diverticulum. In this series, 97% of cases had a benign histology. These findings are important when counseling patients regarding treatment options. PMID:24860605

    Malignant biliary strictures often present late after the window for curative resection has elapsed. In such patients, the goal of therapy is typically focused on palliation. While historically, palliative measures were performed surgically, the advent of endoscopic intervention offers minimally invasive options to provide relief of symptoms, improve quality of life, and in some cases, increase survival of these patients. Some of these therapies, such as endoscopic biliary decompression, have become mainstays of treatment for decades, whereas newer modalities, including radiofrequency ablation, and photodynamic therapy offer additional options for patients with incurable biliary malignancies.

    Endoscopic management of biliary obstruction has evolved tremendously since the introduction of flexible fiberoptic endoscopes over 50 years ago. For the last several decades, endoscopic retrograde cholangiopancreatography (ERCP) has become established as the mainstay for definitively diagnosing and relieving biliary obstruction. In addition, and more recently, endoscopic ultrasonography (EUS) has gained increasing favor as an auxiliary diagnostic and therapeutic modality in facilitating decompression of the biliary tree. Here, we provide a review of the current and continually evolving role of gastrointestinal endoscopy, including both ERCP and EUS, in the management of biliary obstruction with a focus on benign biliary strictures.

    Acquired ureteral strictures are still treated either with a stent, balloon dilatation, by open surgery or by endoscopic therapy with a `cold knife' or high current density as intubated ureterotomy. The success rates described in the literature range between 50% and 90%. Using the experimental CTH:YAG laser (wavelength 2120 nm) and CT:YAG laser (wavelength 1950 nm), the reduction of invasiveness and of morbidity was evaluated. First, the CTH:YAG laser was investigated on 540 fresh porcine ureters varying the parameters. With a computerized morphometry system, defect depth, defect width, coagulation depth and coagulation width were measured. Then 21 female pigs underwent 7.5 F - 12 F ureteroscopy with CTH:YAG laser, CT:YAG laser, high current density and `cold knife' ureterotomy. An IVP and sacrification with explanation of the whole urinary tract was done on day 6 and around day 60. In practice, laser application via the endoscope was easy to handle and exact cutting was always seen. The CT:YAG laser seems to have the best success results with low ureteral stricture recurrence rates. However, its clinical use remains to be proven.

  6. Management of non-gonococcal urethritis.

    2015-01-01

    Non-gonococcal urethritis (NGU), or inflammation of the urethra, is the most common treatable sexually transmitted syndrome in men, with approximately 20-50 % of cases being due to infection with Chlamydia trachomatis and 10-30 % Mycoplasma genitalium. Other causes are Ureaplasma urealyticum, Trichomonas vaginalis, anaerobes, Herpes simplex virus (HSV) and adenovirus. Up to half of the cases are non-specific. Urethritis is characterized by discharge, dysuria and/or urethral discomfort but may be asymptomatic. The diagnosis of urethritis is confirmed by demonstrating an excess of polymorpho-nuclear leucocytes (PMNLs) in a stained smear. An excess of mononuclear leucocytes in the smear indicates a viral etiology. In patients presenting with symptoms of urethritis, the diagnosis should be confirmed by microscopy of a stained smear, ruling out gonorrhea. Nucleid acid amplifications tests (NAAT) for Neisseria gonorrhoeae, C. trachomatis and for M. genitalium. If viral or protozoan aetiology is suspected, NAAT for HSV, adenovirus and T. vaginalis, if available. If marked symptoms and urethritis is confirmed, syndromic treatment should be given at the first appointment without waiting for the laboratory results. Treatment options are doxycycline 100 mg x 2 for one week or azithromycin 1 gram single dose or 1,5 gram distributed in five days. However, azithromycin as first line treatment without test of cure for M. genitalium and subsequent Moxifloxacin treatment of macrolide resistant strains will select and increase the macrolide resistant strains in the population. If positive for M. genitalium, test of cure samples should be collected no earlier than three weeks after start of treatment. If positive in test of cure, moxifloxacin 400 mg 7-14 days is indicated. Current partner(s) should be tested and treated with the same regimen. They should abstain from intercourse until both have completed treatment. Persistent or recurrent NGU must be confirmed with microscopy

  7. Sigmoid stricture at colonoscopy--an indication for surgery.

    Strictures of the sigmoid colon continue to pose a diagnostic dilemma. They commonly appear to be due to diverticular disease but carcinoma must always be excluded. In some cases diverticula may be present but in others there is no obvious cause for the stricture. In a series of 1039 consecutive colonoscopies performed between 1984 and 1986, 19 cases of sigmoid stricture that could not be negotiated with the colonoscope were encountered. In each case the cause of the stricture could not be demonstrated. Fifteen patients (79%) underwent laparotomy primarily on clinical grounds or with barium enema findings suggestive of carcinoma. A final diagnosis of diverticular disease was made in nine cases and adenocarcinoma is six cases. Barium enema was a poor predictor of malignancy in a stricture. Four patients were treated conservatively and two of these patients continued to have significant symptoms due to diverticular disease. This experience suggests that sigmoid strictures that prevent the passage of a colonoscope should be resected when the cause of the stricture is not apparent. PMID:2212846

    Urethral prolapse (UP) is a circular complete eversion of the distal urethral mucosa through the external meatus. It is a rare condition seen mostly in African-American premenarcheal girls. Both a medical and a surgical approach to this condition have been described. We present a case of a spontaneous urethral prolapse in a 60-year-old postmenopausal Caucasian woman, who failed medical management and underwent successful surgical management. The patient is asymptomatic 18 months following the procedure. PMID:25140273

    The objective of this study was to develop and preliminarily test the measuring principle suitable for quantification of the capability of deformation of the inner urethral wall, i.e. quantification of inner urethral wall softness. The special measuring catheter was made of plexiglass with two conically shaped stainless steel electrodes mounted 5 cm from its distal tip. The principle of indirect compression measurement on the basis of impedance changes between the electrodes due to the introduction of the tissue between them was tested. The changes in impedance were measured in the distal male urethra during external manual compression, and in the anal sphincter during voluntary contractions and during coughing. The results obtained confirm the applicability as well as the significance of a further perfection of the new method. Calibration technique of the transducer was developed and tested in NaCl solution. PMID:7199730

    A flexible strip that incorporates multiple pressure sensors and is capable of being fixed to a urethral catheter is developed. The urethral catheter thus instrumented will be useful for measurement of pressure in a human urethra during urodynamic testing in a clinic. This would help diagnose the causes of urinary incontinence in patients. Capacitive pressure sensors are fabricated on a flexible polyimide-copper substrate using surface micromachining processes and alignment/assembly of the top and bottom portions of the sensor strip. The developed sensor strip is experimentally evaluated in an in vitro test rig using a pressure chamber. The sensor strip is shown to have adequate sensitivity and repeatability. While the calibration factors for the sensors on the strip vary from one sensor to another, even the least sensitive sensor has a resolution better than 0.1 psi. PMID:26738054
