Purpose: Successful primary bladder exstrophy closure provides the best opportunity for patients to achieve a functional closure and urinary continence regardless of the method of repair. Use of osteotomy during initial closure has significantly improved success rates. However, failures can still occur. We identify factors that contribute to a failed primary exstrophy closure with osteotomy. Materials and Methods: We reviewed a prospectively maintained institutional database for classic bladder exstrophy cases primarily closed with osteotomy at our institution or referred after primary closure between 1990 and 2015. Data were collected regarding patient gender, closure, osteotomy, immobilization, orthopedics and perioperative pain control. Univariate and multivariable analyses were performed to determine predictors of failure. Results: A total of 156 patients met inclusion criteria. Overall failure rate was 30% (13% from our institution and 87% from referrals). On multivariable analysis use of Buck traction (OR 0.11, 95% CI 0.02–0.60, p = 0.011) and immobilization time greater than 4 weeks (OR 0.19, 95% CI 0.04–0.86, p = 0.031) had significantly lower odds of failure. Osteotomy performed by general orthopedic surgeons had significantly higher odds of failure (OR 23.47, 95% CI 1.45–379.19, p = 0.027). Type of osteotomy and use of epidural anesthesia did not significantly impact failure rates. Conclusions: Proper immobilization with modified Buck traction and external fixation, immobilization time greater than 4 weeks and undergoing osteotomy performed by a pediatric orthopedic surgeon are crucial factors for successful primary closure with osteotomy.

PURPOSE The authors have reviewed the use of muscle pedicle flaps for the treatment of failed bladder neck closure in exstrophy spectrum patients. METHODS A retrospective review of all exstrophy spectrum patients who underwent continence procedures with the use of muscle pedicle flaps at our institution during the last 15 years was performed. Patient characteristics, surgical history, and outcomes, including complications, continence, morbidity, and infection, were assessed. The authors utilized muscle pedicle flaps in eight exstrophy patients, including four patients with classic bladder exstrophy and four patients with cloacal exstrophy. Seven of eight patients had failed at least one prior bladder neck closure, and they had undergone a median of three prior urologic procedures. To achieve continence, five rectus muscle flaps and three gracilis muscle flaps were utilized in combination with bladder neck closure. RESULTS There were no major intraoperative or postoperative complications. All patients were initially continent, and after a median follow-up of 18.7 months seven of eight patients were continent. One patient required continent urinary stoma revision and one patient developed perineal incontinence after perineal trauma. No patients required revision of, or additional, continence procedures at the bladder neck. DISCUSSION The use of pedicle muscle flaps appears to be a safe and feasible option for exstrophy spectrum patients with failed bladder neck closure. Although achieving continence can be difficult in this population, use of muscle flaps and bladder neck closure is a viable and effective option in this challenging subset of patients.

Repair of Vesicocutaneous and Urethrocutaneous Fistulae with Rectus Muscle Flap in a Bladder Exstrophy Patient

Urinary continence can be achieved in up to 90% of patients with bladder exstrophy. However, select patients remain incontinent despite modern reconstruction. Repeat operations for continence combined with the congenital pelvic abnormalities of exstrophy put patients at risk for urinary fistula formation. We report the use of a rectus muscle flap in the repair of two concomitant vesicocutaneous and urethrocutaneous fistulae in a patient with classic bladder exstrophy.

OBJECTIVE To provide sexual function and quality of life outcomes in patients with severe penile deficiency who underwent radial forearm flap phalloplasty with and without penile prosthesis implantation. PATIENTS AND METHODS Patients with history of severe penile deficiency who underwent microsurgical radial forearm flap phalloplasty with and without penile prosthesis implantation between 2007 and 2014 were identified. They completed a set of web-based validated questionnaires including the International Index of Erectile Function, the Pediatric Penile Perception Score, the Sexual Quality of Life for Men, and several items addressing general quality of life. Outcomes were compared between groups. RESULTS Nine of the 12 identified patients who had prosthesis after phalloplasty and 4 out of the 7 phalloplasty-only patients completed the survey, resulting in an overall response rate of 68%. Among the phalloplasty-prosthesis patients, 66% reported current sexual activity and 78% reported regular masturbation, whereas 1 of the 4 phalloplasty-only patients reported both. Prosthesis patients scored notably higher in all domains of the International Index of Erectile Function except for sexual desire. In contrast, they demonstrated similar scores of penile perception, as well as general and sexual quality of life. CONCLUSION Among patients who have undergone flap phalloplasty, the subsequent placement of penile prosthesis appears to effectively allow for both intercourse and masturbation, resulting in measurable improvements in orgasmic function, intercourse satisfaction, and overall sexual satisfaction. Despite these important benefits, prosthesis placement does not appear to result in improvements in penile perception scores, or general or sexual quality of life.

Duplicated Renal Collecting System With Ectopic Ureter in Female Bladder Exstrophy: A Case Report

Pokket Sirisreetreerux; Kathy Lue; Jason E. Michaud; Heather N. Di Carlo; John P. Gearhart

Bladder exstrophy is a rare major birth defect which requires specialized surgical care. Associated genitourinary tract anomalies are extremely rare in this population, yet significantly impact surgical planning and outcomes. In this case, a full-term newborn girl with a prenatal diagnosis of classic bladder exstrophy was found to have a complete duplicated left collecting system with an ectopic ureter inserted to urethral plate. The patient underwent modern staged repair of exstrophy with bilateral anterior innominate osteotomies and concomitant ureteral reimplantation-the first reported case of ureteral reimplantation at the time of initial closure in a newborn.

OBJECTIVE To explore the use of concomitant bladder neck reconstruction (BNR) and creation of a continent stoma (CS) in patients who are not quite eligible for BNR but still strongly desire volitional voiding. METHODS The authors retrospectively reviewed an institutional database of patients with exstrophy-epispadias complex who underwent BNR-CS between 2000 and 2015. Indications for a BNR-CS, perioperative outcomes, and continence status were evaluated. Method of voiding and continence status were analyzed for patients with greater than 6 months of follow-up after the BNR-CS. RESULTS A total of 24 patients with exstrophy-epispadias complex (15 male and 9 female) underwent BNR-CS at a median age of 8.9 years (range 5.4-17.4). This included 18 patients with classic bladder exstrophy, 5 with epispadias, and 1 with a cloacal exstrophy variant. There were 5 surgical complications (20.1%) following the BNR-CS, including 3 febrile urinary tract infections, 1 superficial wound infection, and 1 urethrocutaneous fistula. The median follow-up time from the time of BNR-CS was 1.1 years (range 0.1-14.1). Seventeen of 24 patients (71%) had a follow-up greater than 6 months and were evaluated for continence. Twelve patients (71%) were completely dry for intervals greater than 3 hours following BNR-CS. Five (29%) did not achieve continence with BNR-CS. Of those 5 patients, 3 (60%) underwent subsequent bladder neck transection. CONCLUSION Combined BNR and CS is a suitable alternative to achieve urinary continence in patients who are not ideal candidates for BNR alone. This approach can offer a select group of patients the opportunity for volitional voiding.
