Kock pouch is defined as what?

Kock pouch is defined as what?

• A. External pouch attached to a loop of intestine
• B. Ileal conduit urinary diversion
• C. Reduction of stoma size via plastic ring
• D. Surgical creation of an internal pouch or reservoir to collect effluent

Answer: (D)

A Kock pouch is a continent urinary reservoir created from a segment of ileum that forms an internal pouch to store urine. It includes a mechanism (valve) and a catheterizable stoma so urine can be drained on demand by intermittent catheterization, keeping urine contained rather than continuously leaking into an external bag. This is why the definition describes surgical creation of an internal pouch or reservoir to collect effluent. The other options describe an external ostomy, a non-continent ileal conduit, or a stoma size reduction, none of which define a Kock pouch.
