The Barnett continent ileal reservoir is a modification of which pouch?

• A. It is a modification of the Kock pouch
• B. It predates the Kock pouch
• C. It is a modification of the J-pouch
• D. It uses colon tissue

Answer: (A)

The concept being tested is how urinary continent reservoirs are developed from ileal tissue. The Barnett continent ileal reservoir is built as a modification of the Kock pouch, which was the original continent ileal reservoir using an ileal segment and a continence valve to prevent leakage between catheterizations. The Barnett design preserves that same underlying idea—creating a reservoir from ileum with a continent outlet—but refines the technique to improve continence and ease of catheterization. It does not use colon tissue, and it is not a predated version of the Kock pouch, nor is it the J-pouch used for intestinal continuity.
