An ileal conduit urinary diversion is a surgical technique used for the diversion of urine after a patient has had their bladder removed, usually in radical cystectomy. It is usually used in conjunction with radical cystectomy in order to control invasive bladder cancer.

To create an ileal conduit, the ureters are surgically unattached from the bladder and made to drain into a detached section of ileum (a part of the small intestine). The end of the ileum is then brought out through an opening (a stoma) in the abdominal wall. The urine is collected through a bag that attaches on the outside of the body over the stoma. The bag must be periodically emptied of urine.
