Cutaneous continent reservoir (also called an Indiana pouch)

This figure depicts one option for people who have a cystectomy (bladder removal) for bladder treatment. A reservoir (like a pouch) may be created under the skin of the abdomen using tissue from the stomach or intestines. Urine collects in the pouch, and the patient uses a catheter (a thin tube) to empty the pouch periodically. It is not necessary to wear a drainage bag. This is called a continent cutaneous diversion (commonly referred to as an Indiana pouch).
