Monti's procedure as an alternative technique in complex urethral distraction defect

Area of Science:

• Urology
• Surgical Reconstruction
• Medical Devices

Background:

• Pelvic fracture urethral distraction defects often require end-to-end anastomotic urethroplasty.
• Complex posterior urethral defects post-trauma, especially after failed prior surgeries, present significant reconstructive challenges.
• Appendix urinary diversion is an option, but appendix availability can be limiting.

Purpose of the Study:

• To evaluate the efficacy of the Monti channel urinary diversion technique for managing patients with extensive urethral defects.
• To assess the Monti procedure as an alternative for patients with a history of multiple failed urethroplasties.

Main Methods:

• The study included 8 male patients (age 28-76) with long urethral defects and prior failed reconstructions.
• A 2-2.5 cm ileal segment was used to create a conduit around a urethral catheter.
• The ileal conduit was fashioned as a urinary diversion, similar to an appendix.

Main Results:

• All patients successfully used the Monti conduit for catheterization without stomal stenosis.
• One patient experienced mild incontinence, which resolved with catheterization interval adjustments.
• No complications such as dehiscence, necrosis, or perforation of the conduit were observed.

Conclusions:

• The Monti channel urinary diversion is a valuable technique for complex, long urethral defects unresponsive to standard urethroplasty.
• This method provides a successful reconstructive option for challenging cases in urology.
