User:Wikiwheels93/Mitrofanoff procedure

A catheter is used to drain urine from the channel. The opening on the surface of the skin through which the catheter passes is called a stoma. It is generally located in the belly button or nearby the belly button for easy access.

Description of procedure
A surgeon creates a small channel using the appendix or in the absence of the appendix, a piece of small bowel. One end of the channel is sewn to the skin, creating an opening on the surface called a stoma. The other end of the channel is sewn to the bladder and a flap valve of tissue is created to prevent leakage from the stoma between catheterizations. Sometimes, the bladder is enlarged with bowel tissue to enable greater urine storage in an additional procedure called bladder augmentation. The Mitrofanoff procedure is different from an indwelling catheter placement because the catheter is removed from the channel between urine drainage events.
