Clinical Experience with Ureteroscopic Management of Ureteral Calculi Including Electrohydraulic Lithotripsy / 대한비뇨기과학회지

ABSTRACT

Rigid ureteroscopy is new one of established technique for the management of ureteral stones. Manipulation of calculi can be done under direct vision using flexible forceps or stone baskets with increased safety and efficacy. We have used a 5Fr. electrohydraulic lithotripsy to disintegrate stones that were two large to b removed by manipulation. Between May 1988 and October 1989. 140 ureteroscopies were performed for removal of ureteral stones. In 119 cases(85 %) the stone was removed successfully. Electrohydraulic lithotripsy was used successfully to remove the stone in 25 among 28 cases(89.3%). We conclude that ureteroscopic removal of ureteral stone under direct vision is a safe and effective method for treatment of ureteral stone.
