Preoperative Bladder Capacity Predicts Social Continence following Bladder Neck Reconstruction in Children Born with Exstrophy–Epispadias Complex

Abstract

Introduction The aim of the study is to review the continence and volitional voiding rate in a single center cohort of exstrophy–epispadias patients following Young-Dees-Leadbetter bladder neck reconstruction and to explore factors which predict continence.

Materials and Methods Children who underwent Young-Dees-Leadbetter bladder neck reconstruction as a final stage of repair in a large single low-volume center in a small-population country between 1997 and 2019 were included. Demographic and clinical details were extracted from the patients' charts. The primary end point was continence and volitional voiding. Patients were categorized as incontinent, socially continent (daytime dry intervals > 3 hours, wet nights) and fully continent (daytime dry intervals > 3 hours, dry nights).

Results The study cohort included 27 patients whose median age at reconstruction was 5 years, and median follow-up was 7.8 years (interquartile range [IQR] 6–11.2). The cohort included 24 classic exstrophy patients (89%, 17 males and 7 females) and 3 isolated complete epispadias patients (11%, 1 male and 2 females). Nine (33%) patients achieved full continence and social continence was achieved by nine (33%) patients, for an overall social continence rate of 67%. Preoperative bladder capacity of 110 mL or more was associated with achieving social continence (odds ratio = 6.4, p = 0.047). The overall volitional voiding rate was 67%.

Conclusion Young-Dees-Leadbetter bladder neck reconstruction yielded rates of 33% for full continence and 67% for social continence and volitional voiding. These rates are comparable to those of large high-volume centers. A preoperative capacity of 110 mL or more was the sole predictor of social continence.
