Which ostomy is typically marked in the right lower quadrant for urinary diversion?

• A. Ileal conduit
• B. Indiana pouch
• C. Kock pouch
• D. Ureterostomy

Answer: (A)

The key idea is how stoma location is chosen based on the type of urinary diversion. The ileal conduit is the most common urinary diversion and uses a segment of ileum brought out to the abdominal wall as a noncontinent stoma. Marking this stoma in the right lower quadrant provides a practical, accessible site that aligns with the ileal conduit’s route, makes appliance fit easier, and allows gravity-assisted drainage into the ostomy pouch while staying away from the belt line. Continent reservoirs, like the Indiana pouch or Kock pouch, involve a catheterizable stoma and can be placed in various locations depending on the surgeon and patient anatomy, so they don’t have the same uniform right-lower-quadrant convention. Ureterostomies are less common and their stoma location varies.
