Complications after bladder augmentation in children.

Area of Science:

• Pediatric Urology
• Surgical Innovation
• Reconstructive Surgery

Background:

• Bladder augmentation is crucial for managing complex bladder anomalies.
• Patients with spina bifida, myelomeningocele, and bladder exstrophy often require surgical intervention due to medication intolerance.
• Enhancing bladder capacity and reducing urinary system pressure are key treatment goals.

Purpose of the Study:

• To evaluate the efficacy and outcomes of bladder augmentation in pediatric patients.
• To assess the impact of bladder augmentation on renal function and vesicoureteral reflux.
• To analyze complications associated with bladder augmentation procedures.

Main Methods:

• Retrospective study of pediatric patients undergoing bladder augmentation between 2000 and 2011.
• Analysis of surgical techniques including ileal loop and ureter augmentation.
• Inclusion of continent urinary diversion techniques like Mitrofanoff conduit and Macedo technique.

Main Results:

• 34 pediatric patients (ages 4-17) underwent bladder augmentation, primarily using ileal loops.
• Significant increase in mean bladder capacity from 152.5 ml to 410 ml.
• High success rate in resolving or improving vesicoureteral reflux (83.5% right, 75% left); 3 patients required renal transplant; complications included lithiasis and conduit perforation.

Conclusions:

• Bladder augmentation is an effective procedure for pediatric patients with bladder anomalies.
• The surgery demonstrated positive outcomes in increasing bladder capacity and managing urinary issues.
• Renal function was preserved in the majority of patients, highlighting the procedure's safety and efficacy.
