Which statement best describes Neobladder function?

• A. Reroutes the ureters directly to the abdominal surface
• B. Uses a piece of ileum to create a conduit
• C. Stores urine in a pouch that drains via the urethra
• D. Mimics the function of a urinary bladder; a portion of intestine is formed into a pouch connected to the urethra

Answer: (D)

Neobladder function focuses on recreating a bladder-like reservoir from a piece of intestine that stores urine and allows voluntary emptying through the urethra. This approach aims to preserve a natural voiding route and continence by connecting the intestinal pouch to the urethra, so urine is stored in the reservoir and then voided similarly to a normal bladder.

That’s why the best description is a pouch formed from intestine connected to the urethra and designed to mimic bladder function—creating a reservoir that stores urine and can be emptied via the natural outlet.

Rerouting the ureters to the abdominal surface describes a urinary diversion with a stoma (not a bladder-like reservoir). Using a segment of ileum to make a conduit describes an ileal conduit, which channels urine to a stoma and does not provide urethral voiding. Describing a pouch that drains via the urethra captures part of the idea but doesn’t explicitly emphasize that it mimics bladder function with a reservoir connected to the urethra.
