Endoscopic surgery of calculi in ureteroceles

Abstract

Of 366 patients with lower ureteral calculi operated upon by the author, 25 (6.83%) had a stone in a ureterocele. Operation is necessary as these stones cannot pass spontaneously. If endoscopic surgery is undertaken, the following must be taken into account: the ureteral tone, and the size, number and type of ureterocele. In all of our cases we used an endoscopic 'smiling mouth' incision, associated in 6 cases with lithotrity. We obtained good results in 22 cases and in only 1 case was vesicoureteral reflux found postoperatively.
