A congenital obstruction of the ureteric orifice with a hyperechoic septation within the bladder at the ureteric orifice is called?

• A. Ureterocele
• B. Bladder diverticulum
• C. Ureteropelvic junction obstruction
• D. Cystocele

Answer: (A)

Ureterocele is a congenital dilation of the distal ureter within the bladder caused by a narrowed vesical opening, producing a cystic structure at the ureteral orifice. The finding described—a cystic, intravesical structure at the site of the ureteric orifice with a hyperechoic septation inside—is a classic ultrasound appearance of a ureterocele, reflecting the obstructed distal ureter with folded or mucosal tissue forming a septum. This differentiates it from other conditions: a bladder diverticulum is a wall outpouching, not specifically at the ureteric orifice; a cystocele is bladder prolapse into the vagina; and ureteropelvic junction obstruction is located at the renal pelvis, not at the bladder opening.
