Which urinary diversion is most common and uses an ileal conduit with a stoma?

• A. Cutaneous Urostomy
• B. Continent Urinary Reservoir
• C. Conventional Urostomy
• D. Neobladder

Answer: (C)

When urine is diverted to the skin through a stoma using a segment of intestine, the setup is a noncontinent diversion that is the standard, most commonly performed type after cystectomy. An ileal conduit is created by isolating a short piece of ileum, attaching the ureters to this segment, and bringing one end out to the abdominal wall to form a stoma. The urine drains continuously into an external ostomy pouch, with no dedicated reservoir or mechanism for voluntary continence. This is why the conventional urostomy best fits the description: it specifically refers to the ileal conduit with a cutaneous stoma, the most common form of urinary diversion. Continent urinary reservoirs and neobladders use internal reservoirs and require catheterization or voiding through the urethra, which differs from the ileal conduit’s stoma-based, noncontinent approach. The cutaneous urostomy term is closely related, but the traditional, widely recognized designation for the ileal conduit with a skin stoma is the conventional urostomy.
