Which urinary diversion is connected to the urethra and aims to replicate normal urination?

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

Answer: (D)

The key idea is a urinary diversion that stays connected to the urethra and lets the patient urinate through the natural route. A neobladder uses a segment of bowel fashioned into a reservoir that is attached to the urethra, so urine can be stored and voided through the urethra, mimicking normal urination. It requires an intact outlet (sphincter/pelvic floor) and patient training to void, often with a gradual return of sensation and some potential leakage at first. In contrast, a cutaneous urostomy channels urine out through a stoma on the abdomen, not the urethra. A conventional urostomy is similar. A continent urinary reservoir stores urine but is drained by catheterization through a stoma, not by urinating through the urethra, so it doesn’t replicate normal urination.
