Where is bladder diverticulum usually located?

• A. Near the bladder neck
• B. Near the urethral orifice
• C. At the bladder dome
• D. In the urethra

Answer: (B)

Bladder diverticula form when the mucosa herniates through a weakened detrusor muscle, and they tend to appear in areas of highest wall stress near the bladder neck where the outlet opens to the urethra. This region endures greater pressure during voiding, making it a common site for mucosal outpouching to occur. Ultrasound typically shows a pouch that communicates with the bladder lumen in that vicinity, which is why the near the urethral orifice spot is considered the usual location. Other regions, like the bladder dome or within the urethra itself, are less typical for primary diverticula.
