Which are listed as less common incontinent urinary diversions?

• A. Ureterostomy and Vesicostomy
• B. Indiana pouch and Mitrofanoff procedure
• C. Orthotopic neobladder
• D. Urostomy

Answer: (D)

The main idea here is understanding which urinary diversions are typically incontinent and how commonly they’re used. Ureterostomy and vesicostomy are both forms that drain urine directly to an external appliance without creating a reservoir to store urine. Because they provide straightforward drainage and are used for more limited or specific clinical situations, they’re less commonly performed compared with the more versatile and widely adopted urostomy (ileal conduit) and the continent diversions.

A urostomy (ileal conduit) is the standard incontinent diversion, creating a reservoir-like conduit with an external ostomy bag, making it a common option. Continent diversions such as the Mitrofanoff and Indiana pouch involve reserving urine in a pouch and allow controlled emptying, usually by catheterization, which is why they’re not considered incontinent. An orthotopic neobladder aims for near-normal continence with voiding through the urethra, also not an incontinent diversion.

So the combination that’s listed as less common incontinent diversions is ureterostomy and vesicostomy.
