Bilateral intravesical duplex system ureteroceles with multiple calculi in an adult patient.

We present a case report of an adult female patient with bilateral duplex system ureteroceles, containing multiple small stones. There was no history of urinary tract infections or stone disease. Treatment consisted of right upper pole heminephrectomy because of non-function and transurethral incision of the left ureterocele, resulting in almost complete removal of the calculi. Furthermore no vesicoureteral reflux was seen 3 months postoperatively. Transurethral incision is a safe and effective treatment in removing stones in ureteroceles without necessitating further treatment because of vesicoureteral reflux.
