Recurrent urethral stricture is one of the biggest problems in urology. Urethral stents as an alternative treatment to traditional methods  has been used since  1985    in the treatment of urethral strictures. The stone formation in the Memotherm urethral stent implantation area is a rare complication. We report the case of a 67-year-old man who presented a stone in the Memotherm urethral stent implantation area after 6 years from the urethral stent surgery.

Abstract Objectives To evaluate objective treatment success and subjective patient-reported outcomes in patients with radiation-induced urethral strictures undergoing single-stage urethroplasty. Patients and methods Monocentric study of patients who underwent single-stage ventral onlay buccal mucosal graft urethroplasty for a radiation-induced stricture between January 2009 and December 2016. Patients were characterized by descriptive analyses. Kaplan–Meier estimates were employed to plot recurrence-free survival. Recurrence was defined as any subsequent urethral instrumentation (dilation, urethrotomy, urethroplasty). Patient-reported functional outcomes were evaluated using the validated German extension of the Urethral Stricture Surgery Patient-Reported Outcome Measure (USS PROM). Results Overall, 47 patients were available for final analyses. Median age was 70 (IQR 65–74). Except for two, all patients had undergone pelvic radiation therapy for prostate cancer. Predominant modality was external beam radiation therapy in 70% of patients. Stricture recurrence rate was 33% at a median follow-up of 44 months (IQR 28–68). In 37 patients with available USS PROM data, mean six-item LUTS score was 7.2 (SD 4.3). Mean ICIQ sum score was 9.8 (SD 5.4). Overall, 53% of patients reported daily leaking and of all, 26% patients underwent subsequent artificial urinary sphincter implantation. Mean IIEF-EF score was 4.4 (SD 7.1), indicating severe erectile dysfunction. In 38 patients with data regarding the generic health status and treatment satisfaction, mean EQ-5D index score and EQ VAS score was 0.91 (SD 0.15) and 65 (SD 21), respectively. Overall, 71% of patients were satisfied with the outcome. Conclusion The success rate and functional outcome after BMGU for radiation-induced strictures were reasonable. However, compared to existing long-term data on non-irradiated patients, the outcome is impaired and patients should be counseled accordingly.

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.

The male urethral stricture treatment is actual clinical issue with its resolution being increasingly frequently based on application of minimum invasive therapeutic interventional uroradiology methods. Since the methodology is applied over the last two decades, the most reasonable therapeutic algorithm has not been defined yet with respect to the correlation with the contemporary surgical treatment. The results of application of the temporary covered self-expandable nitinol Allium stents, which have been applied for the first time ever at our Institution in October 2003. Over the last 3 years, the method was applied in 40 males, averagely aged 54 years with urethral strictures previously treated by urological methods. In four cases, stent placement was performed after endourethral incision. The most common etiology of the stricture was the posttraumatic (55 %), post-inflammatory (32%) and iatrogenic (10%). In all the cases, stents were removed 12-14 months after their insertions. The results are evaluated using uroflowmetry and urethrocystography, revealing in 85% of the cases permanent recanalization free of dysuric complaints. Development of a stricture on the anterior stent end was evidenced in 15% of the cases.

Congenital urethral strictures are well recognised in human beings and have recently been described in two cats but have not been previously reported in dogs. A 10-month-old female English Bull Terrier presented with a life-long history of being unable to pass a normal stream of urine. Urethrocystoscopy confirmed the presence of a stricture lesion in the proximal urethra. This thin, membranous structure was effaced under endoscopic visualisation using a 10 mm diameter balloon-dilation catheter. Complete and sustained resolution of clinical signs occurred after a single dilation procedure. To the best of our knowledge, this is the first report of a congenital urethral stricture in a dog and the term congenital obstructive proximal urethral membrane may be useful for describing these lesions in the future.

Surgical clip migration is a rare complication of laparoscopic cholecystectomy (LC). Surgical clips migrating into the common bile duct (CBD) can lead to stone formation and obstruction. Here, we report a case of acute cholangitis caused by surgical Hem-o-lok clip migration into the bile duct with stone formation 13 months after LC. A 65-year-old man who underwent LC presented with upper abdominal pain and fever for 3 days. Abdominal CT scan showed a radiopaque material in the CBD, diffuse wall thickening and dilatation of intrahepatic and extrahepatic duct. Emergency percutaneous transhepatic biliary drainage was performed. Twodays later, an endoscopic retrograde cholangio-pancreatography was implemented, and muddy stones and one surgical clip were successfully removed by extraction balloon catheter.

Urethral strictures are common and almost all urologists will deal with them on a regular if not daily basis. They have always been common and the history of the subject stretches back to 3,000 BC. Urethral dilators have been found in the tombs of the pharaohs so that they might be able to catheterize themselves or dilate their own strictures in the afterlife. Urethrotomy and dilatation are two of the most frequently performed procedures in urology. But these are usually only palliative, and curative treatment by urethroplasty is performed by very few urologists. In part this is because most strictures are bulbar strictures and most non-bulbar strictures are seen only by reconstructive urologists; but in part this represents a somewhat ambivalent attitude of most urologists to urethral stricture disease. In this chapter, we will attempt to clarify the current approach to this problem.

87 Background: Urethral strictures (US) are a rare complication of prostate brachytherapy (BXT), with prior studies showing radiation dose to the bulbomembranous urethra is associated with stricture formation. This retrospective case-control study explored clinical and dosimetric parameters associated with the development of BXT-related urethral strictures. Methods: A cohort of 34 patients developed urethral strictures after BXT at our institution for the period of 2008-2014. Each case was matched with two controls (68 controls) that had not developed a US according to similar baseline International Prostate Symptom Score (IPSS), planned prostate volume, post-implant prostate V150, and post-implant prostate D90 dosimetry parameters. US development was compared with clinical (i.e. age, IPSS, etc) and dosimetric (i.e. prostate, urethra, urethra segments) variables. Statistical modeling for risk prediction was applied, which included adjusted R2, Mallows’ C Selection (Cp), Schwartz’s information criterion (BIC), forward selection (FS), and backward selection (BS) to identify the parameters with prediction ability of toxicity. CV analysis was performed to select the best subset selection on the full data set in order to obtain the most predictive parameter selection. Results: The results show that the R2statistic increases from 6% (only one) to 33 %, (all of the parameters included). The table demonstrates minimum best-fit parameters in the different models. (See table.) CV with minimum standard error (MSE) identified a model with 5 parameters that included age, baseline IPSS, UD30, UD5, and U5mm V200Apex shows best prediction ability for US. Conclusions: This modeling approach, which is novel in BXT, helped to identify a combination of parameters with some predictive ability of radiation toxicity. Further evaluation is required to validation. [Table: see text]
