Abstract

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.
