Diagnosis

Duplicated renal collecting system with obstructed upper pole moiety and ureterocele

Findings

US- Dilated upper pole renal collecting system and dilated ureter terminating in a intravesical cyst.

Discussion

Ectopic ureterocele is almost always associated with a duplicated collecting system and hydronephrosis and dilated and tortuous ureter. It is the result of dilation and protrusion of the intravesical segment of the upper pole ureter into the bladder lumen and bladder neck. The ureterocele distorts the intravesical portion of the adjacent lower pole ureter resulting in a high incidence of vesicoureteral reflux. Depending upon the size, ureteroceles can obstruct or distort the contralateral ureteral orifice or obstruct the urethra. Ectopic ureterocele is the most common cause of bladder outlet obstruction in females. Ectopic ureteroceles are larger and tend to have a broader neck compared to simple ureteroceles.
