A population based analysis of continence outcomes and bladder exstrophy

Area of Science:

• Pediatric Urology
• Reconstructive Surgery
• Genitourinary Development

Background:

• Bladder exstrophy literature often focuses on select cases, lacking data on comprehensive exstrophy populations.
• Understanding continence outcomes across diverse surgical procedures is crucial for urologists and patients.

Purpose of the Study:

• To analyze urinary continence outcomes in a comprehensive bladder exstrophy population.
• To evaluate the impact of various surgical procedures on achieving urinary continence.
• To identify predictors of urinary continence in exstrophy repair.

Main Methods:

• Retrospective chart review of bladder and cloacal exstrophy patients undergoing staged repair (1988-1998).
• Patients categorized into three groups based on bladder neck reconstruction (BNR) type: BNR only, BNR with augmentation/appendicovesicostomy, and bladder neck closure.
• Continence rates correlated with surgical procedures; subgroup analysis performed for predictors.

Main Results:

• Urinary continence rates were 56% (BNR only), 67% (BNR with augmentation/appendicovesicostomy), and 100% (bladder neck closure).
• Females (94%) achieved continence more frequently than males (69%).
• Delayed continence noted in groups with augmentation/appendicovesicostomy (8.2-8.7 years) versus BNR only (4.8 years); repeat BNR success rate was 23%.

Conclusions:

• All patients can achieve urinary continence, though often requiring staged or adjunctive procedures beyond initial bladder neck reconstruction.
• Surgical strategy for failed BNR should consider bladder storage enhancement and augmentation.
• Earlier recognition of the need for storage procedures can improve continence timing, independence, and self-esteem, potentially with fewer operations.
