PURPOSE: Urodynamic study was performed in patients with exstrophy to determine the effect of bladder neck reconstruction and the ability to achieve normal urodynamics following surgery.
MATERIALS AND METHODS: A total of 30 exstrophy cases at different stages of reconstruction were retrospectively reviewed in terms of bladder capacity, compliance, stability and presence of detrusor contractions following urodynamic study.
RESULTS: Bladder capacity increased from a third predicted volume for age to half after reconstruction. Approximately 80% of patients had compliant and stable bladders before bladder neck reconstruction. Following bladder neck reconstruction approximately half of the patients maintained normal compliance with a smaller number maintaining normal stability. A quarter of patients maintained normal filling dynamics following bladder neck reconstruction, and 19% maintained normal filling and voiding dynamics after reconstruction.
CONCLUSIONS: The majority of closed exstrophy bladders have normal filling dynamics before bladder neck reconstruction. Compliance and stability are impaired following bladder neck reconstruction. Approximately 25% of patients with exstrophy may maintain normal detrusor function following reconstruction. However, less invasive alternatives to the Young-Dees-Leadbetter bladder neck reconstruction should be sought.
