BACKGROUND: Our objective is to report a comparative review of recently released guidelines for the evaluation, management, and follow-up of urethral stricture disease. METHODS: This is an analysis of the American Urologic Association (AUA) and Société Internationale d'Urologie (SIU) guidelines on urethral stricture. Strength of recommendations is stratified according to letter grade that corresponds to the level of evidence provided by the literature. RESULTS: Although few, the discrepancies between the recommendations offered by the two guidelines can be best explained by varying interpretations of the literature and available evidence on urethral strictures...

BACKGROUND: Female-to-male gender-confirmation surgery (GCS) includes removal of breasts and female genitalia and complete genital and urethral reconstruction. With a multidisciplinary approach, these procedures can be performed in one stage, avoiding multistage operations. AIM: To present our results of one-stage sex-reassignment surgery in female-to-male transsexuals and to emphasize the advantages of single-stage over multistage surgery. METHODS: During a period of 9 years (2007-2016), 473 patients (mean age = 31...

PURPOSE: To evaluate pre-operative risk factors associated with stricture recurrence in a large, homogenous series of bulbar urethroplasties. MATERIALS AND METHODS: 596 patients undergoing isolated bulbar urethroplasty at a single center from August 2003 to June 2015 were analyzed. Urethroplasty failure was defined as stricture <16Fr identified on cystoscopy with a minimum of 12 months follow-up. Potential risk factors examined were patient age, stricture etiology, stricture length, diabetes, smoking, obesity, Charlson Comorbidity Index, previous endoscopic treatment, previous urethroplasty and type of urethroplasty...

INTRODUCTION: Complex penile strictures are usually repaired using a two-stage urethroplasty. Buccal mucosal graft (BMG) placed in the first stage can have a significant contraction rate, which may require a subsequent revision surgery. We describe a composite two-stage penile urethroplasty using BMG for patients of complex penile strictures who have some salvageable urethral plate. METHODS: Within a multi-institutional cohort, 82 patients underwent a two-stage urethroplasty for complex stricture of the penile urethra...

Introduction. Concealed-buried penis is an acquired condition associated with obesity, challenging to both manage and repair. Urethral stricture is a more common disorder with multiple etiologies. Lichen sclerosus is a significant known cause of urethral stricture, implicated in up to 30%. We hypothesize that patients with buried penis have a higher rate of urethral stricture and lichen sclerosus than the general population. Methods. We retrospectively reviewed a single surgeon's (CM) case logs for patients presenting with a buried penis...

This study aims to investigate the effect of non-transecting anastomotic urethroplasty for treatment of posterior urethral stricture. A total of 23 patients with traumatic posterior urethral stricture were enrolled and then divided into two groups. In one group, 12 patients underwent non-transecting anastomotic urethroplasty. In the other group, 11 patients underwent conventional posterior urethra end-to-end anastomosis. The effect of operation was evaluated using the following parameters: the bleeding amount during operation, operation time, IIEF-5 scores after operation, maximum flow rate (Qmax), and rating scale of quality of life (QoL)...

The article describes a clinical observation of a 68 y/o patient with large stones of the urethra, reaching 5 cm in length and located in the penile urethra. The patient underwent a three-stage treatment: the first stage consisted of drainage of the urinary bladder, the second stage of the urethrolithotomy and a double-barreled fistula, the third was an anastomotic urethroplasty. After removing the cystostomic drainage tube, normal urination was restored.
