Ileal conduit for urostomy is created from which portion of the intestine?

• A. Jejunum
• B. Colon
• C. Ileum
• D. Stomach

Answer: (C)

The segment of intestine used for an ileal conduit is the ileum. This choice is favored because a short, well-vascularized piece of ileum can be isolated while preserving its blood supply, then detubularized and reshaped into a low-pressure, compliant channel to carry urine from the ureters to a stoma on the abdominal wall. Detubularization reduces the segment’s inherent peristalsis and pressure, helping protect kidney function and provide reliable drainage. The distal end is brought out as the skin stoma, and the ureters are implanted into the conduit. Other segments can be used in certain diversions, but the ileum is the standard due to its predictable handling of urine and surgical practicality.
