Which urinary diversion requires no external bag because urine is drained via catheter from a stoma?

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

Answer: (C)

The main idea is how urine is drained from the urinary diversion. A continent urinary reservoir is a pouch created from intestinal tissue that stores urine inside the body and is connected to a catheterizable opening (stoma) on the abdomen. The urine is drained by inserting a catheter through that stoma at intervals, so there’s no ongoing external collection bag. This allows continence between catheterizations and eliminates the need for a bag that collects urine continuously. Other options involve urine flowing out to an external bag via a stoma (conventional or cutaneous urostomy), which requires wearing a bag, while a neobladder typically empties through the urethra rather than through a stoma with intermittent catheterization.
