How We Made Exstrophy Bladder Continent and Preserved the Renal Functions

Area of Science:

• Pediatric Urology
• Surgical Reconstruction
• Continence Management

Background:

• Bladder exstrophy repair aims for both urinary continence and renal function preservation.
• Managing intravesical pressure is critical for successful outcomes in these complex cases.

Purpose of the Study:

• To retrospectively analyze patient data to assess continence and renal function after bladder exstrophy repair.
• To identify key factors contributing to continence and preservation of renal function.

Main Methods:

• Retrospective analysis of 52 patients with bladder exstrophy.
• Focus on 18 fully continent patients, comparing primary repair with augmentation strategies.
• Utilized cystostomy tube (CT) for vesical pressure venting prior to augmentation in most cases.

Main Results:

• All 18 patients achieved a 24-hour dry period; two managed enuresis with fluid restriction.
• Seventeen out of 18 patients maintained preserved renal function.
• Successful outcomes were linked to specific surgical techniques and pressure management.

Conclusions:

• Tension-free abdominal wall closure with rectus muscle apposition is vital for preserving repaired bladder exstrophy.
• Osteotomy aids in preventing reconstruction failure by mitigating lateral forces.
• Venting vesical pressure via CT until timely augmentation is crucial for creating a low-pressure, continent system, safeguarding both continence and renal function.
