Definition

A cutaneous ureterostomy, also called ureterocutaneostomy, is a surgical procedure that detaches one or both ureters from the bladder, and brings them to the surface of the abdomen with the formation of an opening (stoma) to allow passage of urine.

Purpose

The bladder is the membranous pouch that serves as a reservoir for urine. Contraction of the bladder results in urination. A ureterostomy is performed to divert the flow of urine away from the bladder when the bladder is not functioning or has been removed. The following conditions may result in a need for ureterostomy.

• bladder cancer
• spinal cord injury
• malfunction of the bladder
• birth defects, such as spina bifida
