Abstract:
PURPOSE: The authors evaluated of the efficacy of Genestone 190 lithotriptor (Genemed company) for the treatment of the patients with urinary calculi. MATERIALS AND METHOD: From August, 1995 to February, 1997, Seventy patients with venal stones and 103 patients with ureteral stones underwent SWL using fluoroscopy targeting, under intramuscular analgesics. Characteristics of site and size of stones, number of SWL sessions according to the size of stones, success rate according to site or size of stones, and their complications were analysed. RESULTS: The cumulative stone-free rates of first, second, and third SWL session of renal stones were 47%, 74%, and 86% and the cumulative stone-free rates of ureter stones were 65%, 79%, and 87% respectively. As the size of urinary calculi increased, the numbers of SWL sessions increased, but, the success rates were reduced. Success rate of calyx stone was lower than that of pelvis and multiple stone. Post-SWL complications were transient gross hematuria in 161 cases, steinstrasse in 18 cases, renal colic in 15 cases, and fever in one case. CONCLUSIONS: SWL monotherapy with Genestone 190 lithotriptor is a effective, safe and useful treatment modality which can resolve almost all cases of urinary calculi without any clinically significant complications.
