Ileovesicostomy (also known as "cutaneous ileocystostomy", "ileal chimney", or "bladder chimney") is an uncommon urologic diversion in which a loop of small bowel is anastomosed/augmented to the dome of the bladder. This loop of bowel then exits through a urostomy. The diversion is not continent.

The procedure is indicated for severe neurogenic bladder dysfunction. Complete cystectomy with ileal loop diversion or neobladder formation is indicated for bladder cancer.
