Purpose: We evaluated the short and long-term surgical outcomes of urinary diversion done for urinary adverse events arising from prostate radiation therapy. We hypothesized that patient characteristics are associated with complications after urinary diversion.
Materials And Methods: We performed a retrospective cohort study of 100 men who underwent urinary diversion (urinary conduit or continent catheterizable pouch) due to urinary adverse events after prostate radiotherapy from 2007 to 2016 from 9 academic centers in the United States.
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.
Purpose: Subjective measures of success after urethroplasty have become increasingly valuable in postoperative monitoring. We examined patient reported satisfaction following anterior urethroplasty using objective measures as a proxy for success.
Materials And Methods: Men 18 years old or older with urethral strictures undergoing urethroplasty were prospectively enrolled in a longitudinal, multi-institutional urethroplasty outcomes database.
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.
Purpose: Lichen sclerosus is a chronic, inflammatory skin condition of the genitalia of unknown origin that accounts for nearly 10% of urethral stricture disease. In this study we determine systemic comorbidities associated with lichen sclerosus in men.
Materials And Methods: We analyzed data from 1,151 men who were enrolled in a multi-institutional prospective urethroplasty outcomes database.
Objective: To evaluate sexual function after staged penile urethroplasty with oral mucosal graft (OMG).
Methods: We identified men with completed staged penile urethroplasty with OMG from the Trauma and Urologic Reconstruction Network of Surgeons database between January 1, 2010 and May 1, 2014. Our primary outcome was change in total Sexual Health Inventory for Men (SHIM) and total Male Sexual Health Questionnaire Ejaculatory Domain (MSHQ-EjD) Short Form at baseline vs after the second stage of the procedure.
Purpose: Injection of mitomycin C may increase the success of transurethral incision of the bladder neck for the treatment of bladder neck contracture. We evaluated the efficacy of mitomycin C injection across multiple institutions.
Materials And Methods: Data on all patients who underwent transurethral incision of the bladder neck with mitomycin C from 2009 to 2014 were retrospectively reviewed from 6 centers in the TURNS.
Purpose: Anterior urethral stricture disease most commonly presents as urinary obstruction. Lower urinary tract pain is not commonly reported as a presenting symptom. We prospectively characterized lower urinary tract pain in association with urethral stricture disease and assessed the effects of urethroplasty on this pain.

A descriptive analysis of initial management trends following renal trauma was also performed as a secondary analysis.
Methods: With the use of the National Trauma Data Bank, patients with renal injuries were identified, and Abbreviated Injury Scale (AIS) codes were stratified to a corresponding American Association for the Surgery of Trauma (AAST) renal injury grade.
A 55-year-old heterosexual male presented to the emergency department with a symptomatology consistent with urethritis and Fournier's gangrene. Urethral swab and operative tissue cultures were positive for coagulase-negative Staphylococcus and an intracellular Gram-negative diplococcus. The latter was initially thought to be Neisseria gonorrhea; however, DNA sequencing technique confirmed it to be Neisseria meningitidis.
View Article and Find Full Text PDFObjective: To analyze the practice patterns of recently fellowship-trained reconstructive urologists to help guide fellowship program curriculum development and to evaluate the impact that formal reconstructive urology training has on academic urology programs.
Methods: We evaluated the case logs of 7 recently fellowship-trained reconstructive urologists affiliated with US academic institutions from August 2009 to August 2011 (median years in practice = 2, range 1-6 years). We categorized cases into endoscopic, oncological, female, general (nononcological), and reconstructive.
Purpose: We examined the initial management of renal trauma and assessed patterns of management based on hospital trauma level designation.
Materials And Methods: The National Trauma Data Bank is a comprehensive trauma registry with records from hospitals in the United States and Puerto Rico. Renal injuries treated at a member hospital from 2002 to 2007 were identified.
