A Case of Ectopic Ureterocele Associated with Reflux into the Ureterocele / 대한비뇨기과학회지

Ureterocele is a cystic dilatation of the intravesical segment of the ureter. In the ectopic ureterocele the ureteral orifice opens at a point other than its normal upper pole position, usually at the bladder neck or in the urethra, and is commonly associated with the upper moiety of a duplicated collecting system. Reflux into the ipsilateral lower pole ureter occurs in almost 50 per cent of ectopic ureterocele. But reflux into the ureterocele is rare. Recently we experienced a case of ectopic ureterocele associated with reflux into the ureterocele and treated successfully by heminephrectomy and total ureterectomy.
