Clinical Observation on Percutaneous Nephrolithotomy / 대한비뇨기과학회지

ABSTRACT

We have performed percutaneous removal of renal and upper ureteral stones in 26 patients with ACMI percutaneous nephroscope between August 1986 and July 1987. Overall success rate was 73 percent. Removal was successful for 65 percent of the targeted renal stones and 100 percent of the upper ureteral stones with grasping forceps, baskets, ultrasonic lithotripsy, electrohydraulic lithotripsy or a combination of theses procedures. 24 cases were treated in one session, 2 in a two sessions. There was no mortality and the incidence of complications was low. Average post-operative hospitalization time was 5.7 days. The advantages of this technique are that a skin incision of only 2cm is required to remove the stone, hospital days are fewer than the open procedures, rapid recovery, quicker return to work and few significant complications. We conclude that percutaneous techniques are an effective way to handle the majority of renal and ureteral stones.
