Abstract

Objective To evaluate potential predictors of voided continence among bladder exstrophy patients with a history of a failed closure. Patients and methods The authors reviewed all patients who underwent a bladder neck reconstruction (BNR) with a history of one or more failed exstrophy closures between 1979 and 2007. The following data were collected for each patient: number of failures, site of surgery, mode of failure, presence of osteotomy, bladder capacity, need for additional procedures, and continence status. Results Among patients who underwent successful reclosure following one or more failed closures, 52 patients underwent BNR, and 24 (46%) were continent at last follow-up. Bladder capacity was the only variable predictive of voided continence. The median bladder capacity at the time of BNR differed between those who achieved continence (100 mL) and those who did not (65 mL) (p = 0.005). ROC analysis showed an optimal pre-BNR bladder capacity cutoff for predicting future BNR success of between 80 and 100 mL. Conclusion As previously shown in patients with successful primary closure of exstrophy, these data suggest that bladder capacity also has predictive value in the success of BNR after failed exstrophy closure.
