Outcome of bladder exstrophy repair based on age and technique. Single center experience

Abstract

PURPOSE Reconstruction of bladder exstrophy remains a challenge. We evaluated our experience with different techniques in different age groups. MATERIAL AND METHODS A retrospective data review was conducted of bladder exstrophy patients presenting at our institution between May 2000 and September 2007. 61 patients (21 females and 40 males) with classic bladder exstrophy were included. Age of presentation ranged from 24 hours to 14 months. 51 patients underwent complete primary repair and 11 patients had staged repairs. Mean follow up was 3 years (1 month to 7 years). Mortality involved one male & one female (3.2%). 29 patients underwent anterior innominate osteotomy and 9 underwent posterior osteotomy. Patients were evaluated for continence, upper tract dilatation and cosmetic result. RESULTS In the primary repair group, 8 (15.6%) had failed closures and 5 (9.8%) had fistulas. In the staged repair group, 1 (0.9%) had a failed closure and 1 had an epispadic fistula. Evaluation of continence excluded 9 patients recently operated on and 17 patients not followed up at our center. The primary repair group had 15 of 25 dry patients (11 females and 4 males). In the staged repair group, 4 of 10 patients were continent. 4 of our staged cases became dry following augmentation cystoplasty. Upper tract changes were mild during our study (44% of complete repair group and 12.5% in the staged group) with all patients having normal serum creatinine. CONCLUSIONS Patients may require more than one procedure for reconstruction. Continence was better in females than males with primary or staged repairs.
