Mitrofanoff appendicovesicostomy is surgery that uses the appendix to create a channel from the bladder to an opening on the abdomen. A person passes a catheter through this opening to empty the bladder. The channel is designed to resist urine leakage between catheterizations.

Reasons can include certain birth conditions, spinal cord problems, or other causes of impaired bladder emptying. The care team evaluates bladder capacity, pressure, and the person's ability to manage catheterization.
The surgeon connects one end of the appendix to the bladder and the other to a small opening called a stoma on the abdomen. The connection at the bladder is constructed to limit leakage as the bladder fills. Temporary tubes drain urine and protect the new channel during healing.
Catheters remain in place while the bladder and channel heal. The care team then teaches the patient or caregiver how to pass a catheter through the stoma on a regular schedule. Ongoing care includes monitoring drainage and following instructions for cleaning the channel.
The stoma or channel can narrow, making catheter insertion difficult. Urine leakage, infection, and mucus buildup may also occur. Some patients need another procedure to correct a channel or stoma problem.
No. After healing, urine is typically drained by inserting a catheter through the stoma at regular intervals. The catheter is removed after the bladder empties.
A surgeon can create a different catheterizable channel from a segment of intestine if the appendix is unavailable. That alternative is not an appendicovesicostomy.
The channel is designed to remain continent between catheterizations. Leakage can occur if the channel or its valve does not function as intended.
Yes. The operation creates another route for catheterization rather than making the bladder empty on its own. The patient or caregiver must follow the prescribed drainage schedule.
