Which bladder anomaly presents as a pouch-like outpouching of the wall and is often near the urethral orifice?

• A. Vesicoureteral Reflux
• B. Ureterocele
• C. Bladder Diverticulum
• D. Neurogenic Bladder

Answer: (C)

A bladder diverticulum is a pouch-like outpouching that communicates with the bladder lumen through a narrow neck, often seen along the bladder wall near the urethral region. This structure arises when the bladder wall weakens or is exposed to increased pressure, either congenitally or from chronic obstruction, allowing a segment of mucosa and submucosa to herniate outward. On ultrasound you’d look for a sac projecting from the bladder with a connection to the bladder through a narrow neck; it may fill with urine as the bladder empties and refills. This description fits a bladder diverticulum because it emphasizes the characteristic pouch-like projection attached to the bladder wall. Vesicoureteral reflux involves urine flowing backward from the bladder into the ureters, not an outpouching. A ureterocele is a dilation of the distal ureter within the bladder, typically at the ureteral orifice, not near the urethral region. Neurogenic bladder refers to dysfunctional bladder storage and emptying due to nerve impairment, not a structural pouch.
