Which term describes a non-continent urinary diversion?

• A. Ureterosigmoidostomy
• B. Non-continent urostomy
• C. Continent ileal reservoir
• D. Kock pouch

Answer: (B)

Non-continent urinary diversions drain continuously without a storage mechanism. The term that directly describes this type of diversion is non-continent urostomy, which means urine exits through a stoma into an external bag without any continence mechanism to hold it in.

Continent options involve a reservoir that stores urine and a way to control its release, so they are not non-continent. A continent ileal reservoir and a Kock pouch use bowel segments to create a storage chamber with a continence mechanism, allowing controlled voiding. Ureterosigmoidostomy redirects urine into the colon, which also lacks a continence valve, but the standard label for describing non-continent urinary diversions in general is non-continent urostomy.
