    ABSTRACT: Bladder neck contracture (BNC) is a well-described complication of the surgical treatment of benign and malignant prostate conditions. Nevertheless, etiologies of BNC development are highly dependent on the primary treatment modality undertaken with BNC also occurring after pelvic radiation. The treatment options for BNC can range from simple, office-based dilation procedures to more invasive, complex abdomino-perineal reconstructive surgery. Although numerous strategies have been described, a patient-specific approach is usually necessary in the management of these complex patients. In this review, we highlight various therapeutic maneuvers described for the management of BNC and further delineate a tailored approach utilized at our institution in these complicated patients.

    ABSTRACT: Purpose of review: This article discusses etiologic considerations, evaluation, and contemporary approaches to managing rectourethral fistula (RUF) with particular emphasis on geriatric patients. Recent findings: With the advent of multimodal approaches to treating prostate cancer, such as radiation and ablative therapies, the incidence of RUF is increasing, especially in the geriatric population. Surgical repair and healing of RUF in patients with prior radiation is more challenging than in those without prior radiation or ablation because of fibrotic and ischemic changes in surrounding tissues. There is, at present, a lack of consensus over a standardized approach to RUF management because of the heterogeneity in presentation and limited, primarily retrospective, experience in the literature. Nonetheless, an evolving array of surgical approaches now exists for fistula excision and tissue interposition. Summary: Immediate recognition and management of RUF is paramount to prevent related complications. Patient selection and counseling are key to selecting the best approach for repair, whereas a multidisciplinary team, including colorectal and plastic surgery colleagues, may optimize outcomes.

    ABSTRACT: Urethral reconstruction is now considered optimal therapy for most men presenting with symptomatic urethral strictures. The rapid development of innovative tissue transfer techniques over the past decade provides today's reconstructive urologist with a high probability of achieving excellent long-term outcomes after urethroplasty, even in the reoperative setting. Fundamental principles such as accurate initial stricture staging by urethrography, along with critical assessment of both stricture severity and tissue quality during urethroplasty are critical for success. This review illustrates the way in which stricture length, location, severity, and etiology influences the application of reconstructive techniques during contemporary urethroplasty.

    ABSTRACT: IntroductionDistal extrusion of penile prosthesis cylinders is a challenging problem that is associated with pain and imminent erosion through penile skin. Distal extrusion and other perforation injuries, including crural and urethral, are other manifestations of tunica albuginea injuries that result in poor clinical outcomes and patient satisfaction. AimA description of Dr. John Mulcahy's landmark article for management of lateral extrusion is presented along with discussion of techniques for managing other types of perforation injuries associated with penile implants. Methods Dr. Mulcahy's original article is reviewed and critiqued. Surgical methods to manage perforation injuries are discussed. Main Outcomes MeasuresThe main outcome measures used were the review of original article, subsequent articles, and commentary by Dr. Mulcahy. ResultsKnowledge of techniques for management intraoperative and postoperative complications related to tunical perforation is necessary for implant surgeons. Conclusions Perforation injuries are challenging noninfectious complications of penile prosthesis surgery. Familiarity with techniques to manage these problems is essential for ensuring good outcomes and patient satisfaction. Stember DS, Kohler TS, Morey AF.

    ABSTRACT: To present an updated experience using our previously reported lateral perineal '7-flap' technique for perineal urethrostomy (PU), highlighting its role in a variety of patients with advanced urethral stricture disease. All patients who underwent 7-flap PU from 2009-2013 were reviewed. PU was constructed by advancing a "7"-shaped laterally based perineal skin flap into a spatulated, amputated bulbomembranous urethra. The contralateral side of the amputated proximal urethra was then matured to the advanced perineal skin. Patients were stratified by body mass index (BMI) and outcomes were compared. Among 748 patients undergoing urethroplasty during the study period, 22 men (2.9%; mean age 61, range 31-80) received a 7-flap PU for advanced stricture disease (mean follow up 32 months). A majority of patients (14/22, 64%) were obese (BMI = 30). Disease etiologies consisted primarily of lichen sclerosus (9/22, 41%) while 6/22 (27%) had failed prior urethral reconstructions elsewhere. Mean operative time was 108 min (range 54-214), mean estimated blood loss (EBL) was 76 cc (30-200), and all patients were discharged immediately after surgery. Urethrostomy creation was possible in all patients regardless of BMI (mean 33, range 22-43), and there were no differences with regards to EBL (p = 0.71), operative time (p = 0.38), or success rate (p = 0.76) in obese versus non-obese patients undergoing 7-flap PU. Nearly all patients (21/22, 95%) are voiding spontaneously on follow up without the need for any additional procedure. In our updated experience, performance of 7-flap urethrostomy has resulted in durable long term success with acceptable performance in technically challenging cases.

    ABSTRACT: To examine surgical case volume characteristics among certifying urologists associated with treatment of urethral stricture to compare practice patterns of recent graduates to recertifying attending urologists and trends over time. Six month case log data of certifying and recertifying urologists (2003-2013) was obtained from the American Board of Urology (ABU). Cases specifying a CPT code for urethral dilation, direct vision internal urethrotomy (DVIU), urethroplasty and graft harvest in males ≥18 years were analyzed for surgeon-specific variables. Among 6320 urologists logging at least one reconstructive urology procedure, 95,747 (86.2%) urethral dilations, 10,986 (10.0%) DVIU and 4349 (3.9%) urethroplasties were identified, with 99 (0.9%) utilizing graft and 405 (9.3%) staged procedures. Overall ratio of urethral dilation/DVIU to urethroplasty was 24.5:1. More recent log year and new certification correlated with a decrease in ratio of dilation/DVIU to urethroplasty, but stable use of graft. The ratio of dilation/DVIU to urethroplasty for new certification was much lower (7.9:1), compared to first (24.4:1), second (63.3:1), and third recertification cycles (99.5:1), wherein urethroplasty was increasingly rare. Newly certifying urologists performed urethroplasty 4.5 times more often than those recertifying. Academically-affiliated urologists were eight times more likely to perform urethroplasty. Most urethral strictures are treated with dilation/DVIU, but a changing paradigm favoring urethroplasty is evident. Most urethroplasties are performed by a small number of urologists with high volume, academic affiliation, recent residency graduation, and residence in a state with a reconstructive urology fellowship.

    ABSTRACT: To present a novel algorithm for definitive reconstruction of penile curvature in men undergoing inflatable penile prosthesis (IPP) surgery as an alternative to manual penile modeling and grafting procedures. Patients with erectile dysfunction and concomitant penile curvature undergoing IPP placement were divided into two treatment groups: group 1- penile deformity known preoperatively; group 2 - penile curvature recognized intraoperatively after IPP placement. Group 1 patients underwent penile plication after artificial erection and immediately prior to IPP insertion via the same penoscrotal incision, while group 2 patients were treated with a Yachia (Heineke-Mikulicz) corporoplasty over the intact cylinders. Patients completed post-operative Patient Global Impression of Improvement (PGI-I) questionnaires assessing overall satisfaction. Among 405 men receiving IPP at our institution from 2007-2014, 30 patients received synchronous correction of penile curvature (7%). Group 1 included 23/30 (77%) patients, and 7/30 (23%) were in group 2. Overall mean initial curvature was 36° and all patients were corrected to <10°. Average operative times were 18 minutes longer compared to patients who underwent IPP placement alone (82 versus 64 minutes, p<0.05). At an average follow-up of 13 months (range 7-32), 19/20 (95%) group 1 and 6/7 (86%) group 2 patients who completed surveys reported an improved overall condition. No patient reported chronic pain, recurrent deformity, or device malfunction. Penile curvature can be safely and reliably corrected at the time of IPP placement, regardless of whether the deformity was identified preoperatively. Copyright © 2015 Elsevier Inc.

    ABSTRACT: We present a novel technique using ventral slit with scrotal skin flaps (VSSF) for the reconstruction of adult buried penis without skin grafting. An initial ventral slit is made in the phimotic ring, and the penis is exposed. To cover the defect in the ventral shaft skin, local flaps are created by making a ventral midline scrotal incision with horizontal relaxing incisions. The scrotal flaps are rotated to resurface the ventral shaft. Clinical data analyzed included preoperative diagnoses, length of stay, blood loss, and operative outcomes. Complications were also recorded. Fifteen consecutive patients with a penis trapped due to lichen sclerosus (LS) or phimosis underwent repair with VSSF. Each was treated in the outpatient setting with no perioperative complications. Mean age was 51 years (range, 26-75 years), and mean body mass index was 42.6 kg/m(2) (range, 29.8-53.9 kg/m(2)). The majority of patients (13 of 15, 87%) had a pathologic diagnosis of LS. Mean estimated blood loss was 57 cc (range, 25-200 cc), mean operative time was 83 minutes (range, 35-145 minutes), and all patients were discharged on the day of surgery. The majority of patients (11 of 15, 73.3%) remain satisfied with their results and have required no further intervention. Recurrences in 3 of 15 (20.0%) were due to LS, panniculus migration, and concealment by edematous groin tissue; 2 of these patients underwent subsequent successful skin grafting. VSSF is a versatile, safe, and effective reconstructive option in appropriately selected patients with buried penis, which enables reconstruction of penile shaft skin defects without requiring complex skin grafting.

    ABSTRACT: We compared the results of initial excision and primary anastomosis (EPA) urethroplasty to EPA outcomes from other challenging re-operative clinical settings (secondary [prior urethroplasty of any technique other than EPA] and repeat [prior EPA] cases). We reviewed our database of patients who underwent EPA urethroplasty for bulbar urethral stricture at our tertiary referral center from 2007 to 2014. Patients without available data and those with a history of lichen sclerosus, radiation, pelvic fracture urethral injuries, distal strictures and/or hypospadias were excluded from analysis. Patient characteristics and outcomes were compared between those undergoing initial, secondary, and repeat EPA urethroplasty for bulbar urethral stricture. Among 898 urethroplasties performed over the study period, we identified 305 men who underwent EPA urethroplasty of the bulbar urethra (initial EPA 268/305, 88%; re-operative EPA 37/305, 12%). Among re-operative cases, 18/37 (49%) had a secondary EPA following a different type of prior urethroplasty and 19/37 (51%) had a repeat EPA. Repeat EPA in the bulbar urethra was successful in 18/19 patients (95%), which was comparable to the success rate of initial bulbar EPA (251/268, 94%) as well as secondary bulbar EPA (17/18, 94%; P=0.975) with similar mean stricture length. The mean follow up for all patients was 41.5 months (range 6-90 months) and the mean follow up within each group was greater than 30 months. Repeat EPA urethroplasty has excellent results for short bulbar strictures, comparable to those achieved in the initial and secondary setting.

    ABSTRACT: Objectives: To examine case volume characteristics among certifying urologists performing male sling and AUS to evaluate practice patterns in male stress urinary incontinence (SUI). Methods: Six-month case log data of certifying urologists (2003-2013) was obtained from the American Board of Urology (ABU). Cases specifying CPT code for male sling, AUS, and removal or revision of either modality in males ≥18 years were analyzed. Results: Among 1615 urologists (568 certifying and 1047 recertifying) logging at least one male incontinence procedure, 2109 (48% of all procedures) male sling and 2284 (52%) AUS cases were identified. Mean age of patients undergoing AUS was 74.9 years and 67.3 years in sling patients (p<0.001). An increase in male incontinence procedures from 2003 to 2013 was demonstrated. The rate of male sling increased from 32.7% of incontinence surgeries in 2004 to 45.5% in 2013 (p<0.001). Academically affiliated urologists are 1.5 times more likely to perform AUS than male sling for SUI (p<0.001). Median number of slings performed was two (range 1-40), with 32.7% placing slings exclusively. A small group of certifying urologists (3.4%) accounted for 22% of all male slings placed. This same cohort logged 10.2% of all AUS. Surgical management of male SUI varies widely across states (p<0.001), with slings performed between 21-70% of the time. Conclusions: Overall the number of male incontinence procedures has increased over time, with a growing proportion of male slings. Most slings and AUS cases are performed by a small number of high-volume surgeons.
