Mitrofanoff principle

Mitrofanoff principle is a surgical procedure used to create a conduit, or channel, in the body. This conduit is typically used to drain urine from the bladder when normal urination is not possible or desirable. The procedure is named after the French surgeon who first described it, Paul Mitrofanoff.

History

The Mitrofanoff principle was first described in 1980 by French surgeon Paul Mitrofanoff. It was initially used in pediatric patients who were unable to perform clean intermittent catheterization (CIC) through the urethra. Since then, the procedure has been adapted for use in adults and is now a common surgical option for a variety of urological conditions.

Procedure

The Mitrofanoff procedure involves the creation of a conduit, or channel, from the skin surface to the bladder. This is typically done using a section of the patient's own intestine, although other tissues can also be used. The conduit is designed to be non-refluxing, meaning that urine can flow out of the bladder but cannot flow back in. This is achieved by implanting the conduit at an angle into the bladder wall, creating a valve-like effect.

Indications

The Mitrofanoff procedure is indicated for patients who are unable to perform clean intermittent catheterization (CIC) through the urethra. This may be due to physical limitations, such as poor hand function or obesity, or due to anatomical or surgical reasons, such as a narrow or absent urethra. The procedure may also be indicated for patients who prefer not to perform CIC through the urethra for personal or psychological reasons.

Complications

As with any surgical procedure, the Mitrofanoff procedure carries some risk of complications. These may include infection, bleeding, and complications related to general anesthesia. Specific to the Mitrofanoff procedure, there is a risk of conduit stenosis (narrowing), conduit leakage, and bladder stones. Regular follow-up with a urologist is required to monitor for these potential complications.
