Cystectomy in the Pediatric Exstrophy Population: Indications and Outcomes

Area of Science:

• Pediatric Urology
• Reconstructive Surgery

Background:

• Bladder exstrophy is a rare congenital condition requiring complex surgical management.
• Cystectomy is a seldom-used, final surgical option for patients with a non-functional bladder template.

Purpose of the Study:

• To investigate the long-term outcomes and indications for cystectomy in patients with bladder exstrophy.
• To assess the feasibility of achieving urinary continence after cystectomy and urinary diversion in this population.

Main Methods:

• A retrospective review of 1298 patients with exstrophy-epispadias complex was conducted.
• Data on 18 patients who underwent cystectomy between 1970 and 2015 were analyzed, including demographics, indications, surgical history, and outcomes.
• Urinary diversion methods and continence status were specifically evaluated.

Main Results:

• Eighteen patients (15 classic bladder exstrophy) underwent cystectomy, most commonly due to intrinsically poor bladder quality, size, or compliance.
• Urinary diversion varied, including cutaneous ureterostomies, bowel conduits, and continent urinary diversions.
• Eight patients who underwent a continence procedure achieved dryness at a median follow-up of 25.3 months.

Conclusions:

• Cystectomy is indicated for bladder exstrophy patients with small, poor-quality bladders unresponsive to other treatments.
• Achieving urinary continence is possible following cystectomy and appropriate urinary diversion.
• This approach offers a solution for patients with otherwise unsalvageable bladder templates.
