Reconstructing the lower urinary tract: The Mitrofanoff principle.

Area of Science:

• Urology
• Surgical Techniques

Background:

• The Mitrofanoff principle, established in 1980, involves creating a continent catheterizable channel to the bladder using a conduit, bypassing the native urethra.
• Commonly used conduits include the appendix and the Yang-Monti transverse ileal tube.

Purpose of the Study:

• To review the techniques, outcomes, and complications associated with the Mitrofanoff procedure for bladder management.

Main Methods:

• Review of existing literature on the Mitrofanoff procedure, including early and long-term outcomes.
• Comparison of different conduit types (appendix vs. Yang-Monti) and surgical approaches (open, laparoscopic, robotic-assisted).

Main Results:

• The Mitrofanoff procedure has an early reoperation rate of up to 8% for complications like bleeding and anastomotic leaks.
• Stomal stenosis is the most frequent long-term complication, hindering catheterization.
• Overall reoperation rates can reach up to 32% in contemporary series, despite the procedure's implied durability.

Conclusions:

• The Mitrofanoff procedure offers a durable solution for bladder management, particularly for patients needing clean intermittent catheterization.
• Minimizing stomal complications and addressing the significant reoperation rate remain key challenges.
• Long-term outcomes of minimally invasive (laparoscopic and robotic-assisted) Mitrofanoff procedures require further investigation.
