What is the drainage method for an orthotopic neobladder?

• A. Requires external bag
• B. Suprapubic drainage only
• C. Continent diversion to urethra
• D. Incontinent drainage to a stoma

Answer: (C)

Orthotopic neobladder uses a reservoir created from intestinal tissue that is connected to the urethra, allowing urine to be expelled through the natural outlet. This makes it a continent diversion to the urethra—there is no external urine bag or stoma. The patient typically voids via the urethra (often with timed voiding, and sometimes intermittent self-catheterization if needed to empty fully). In contrast, an external bag is used with an ileal conduit, suprapubic drainage describes catheterizing through the abdomen, and a stoma drainage setup corresponds to other urinary diversions. So the drainage method is continent drainage to the urethra.
