Updated experience with the Monti catheterizable channel

Area of Science:

• Pediatric Urology
• Surgical Reconstruction
• Continent Urinary Diversion

Background:

• The Monti catheterizable channel is a key component in continent bladder reconstruction for pediatric patients.
• This study updates the experience with the Monti ileovesicostomy at Riley Children's Hospital.

Purpose of the Study:

• To evaluate the long-term efficacy and safety of the Monti ileovesicostomy in pediatric bladder reconstruction.
• To assess complication rates, surgical revisions, and functional outcomes of the Monti channel.

Main Methods:

• Retrospective review of 199 pediatric patients who underwent Monti ileovesicostomy creation between January 1997 and August 2004.
• Assessment of surgical complications, need for revisions, stomal continence, and catheterization ease.

Main Results:

• High sustained use of the Monti channel for bladder drainage (97.5% of patients).
• Low incidence of early surgical complications (3.5%), particularly in patients with simultaneous bladder augmentation.
• Minor rates of revision (8%) for stomal stenosis, prolapse, or channel issues; infrequent leakage (3.5%).

Conclusions:

• The Monti ileovesicostomy remains a durable and successful technique for bladder drainage in pediatric continent bladder reconstruction.
• Its efficacy is demonstrated in a large patient series, supporting its continued use.
• The procedure is suitable for patients requiring simultaneous appendicocecostomy for stool continence.
