Which tissue is used to create an Indiana pouch reservoir?

• A. Rectum
• B. Sigmoid colon
• C. Small intestines or ascending/transverse colon to create a reservoir for urine collection
• D. Stomach

Answer: (C)

An Indiana pouch is a continent urinary reservoir created from a segment of bowel. The key concept is using detubularized bowel to form a spacious, low-pressure pouch that can store urine and be emptied by catheter through a catheterizable stoma. The tissue chosen for this reservoir is usually from the small intestine or the colon (ascending or transverse colon), which provides enough distensibility and capacity to hold urine.

Rectum isn’t used to fashion this type of reservoir, and the stomach is generally associated with other augmentation procedures rather than forming an Indiana pouch. Using bowel tissue for the reservoir is what makes this option possible, enabling a controllable, catheter-accessible storage site for urine.
