Modification of a Kock pouch procedure is known as which reservoir?

• A. Barnett continent ileal reservoir
• B. Kock pouch with augmentation
• C. IPAA procedure
• D. J-pouch formation

Answer: (A)

In continent urinary diversions, a reservoir is built from an ileal segment with a continence mechanism to allow catheterization without ongoing leakage. The Kock pouch is the classic continence reservoir with a catheterizable stoma and a nipple valve. The Barnett continent ileal reservoir is a well-known modification of this concept, designed to improve continence and ease of catheterization by altering the valve and reservoir configuration. It remains distinct from procedures like IPAA or J-pouch, which create an ileal pouch connected to the anal canal rather than a continent, catheterizable stoma. Therefore, the modification of the Kock pouch is best described as the Barnett continent ileal reservoir.
