Which of the following is among the top four reasons for urinary diversion?

• A. Bladder cancer
• B. Appendicitis
• C. Kidney stones
• D. UTI

Answer: (A)

When a urinary diversion is needed, the bladder is no longer usable to store or pass urine, so urine must be redirected to exit the body through a stoma or a constructed reservoir. Bladder cancer is one of the leading reasons for this because treatment often requires removing the bladder (cystectomy), leaving no functional bladder to drain urine. In that scenario, creating a urinary diversion—such as an ileal conduit or a neobladder—becomes necessary to continue urine elimination. The other options aren’t typical indications: appendicitis is a gastrointestinal condition and doesn’t prompt urinary diversion; kidney stones are usually treated with stone removal or drainage rather than rerouting urine; UTIs are infections and, on their own, do not require diversion unless there’s severe, underlying bladder dysfunction. So bladder cancer is the best choice because it directly leads to loss of bladder function and the need for diversion.
