ABSTRACT
Extracorporeal shock wave lithotripsy monotheraphy was performed in 315 urinary stones from 278 patients with the Domestic SDS-2 lithotriptor using C-arm fluoroscopy between December 1991 and December 1994. Of 315 cases, renal stones were 150 cases(47.6%) and ureteral stones 165 cases(36.1%). No regional or general anesthesia was required but parenteral or oral analgesics were required in some patients. Among 315 cases who completed extracorporeal shock wave lithotripsy, the overall success rate of treatment was 90.5% with 92.4% in 5-9 mm, 94.8% in 10-19 mm, 89.7% in 20-29 mm and 61.5% over 30 mm or staghorn stones. Post lithotripsy complications were transient gross hematuria in 17.1%, renal colic in 11.4%, steinstrasse in 4.8%, petechia in 2.9% and fever in 1.9% and these complications were controlled with conservative treatment or repeated session of extracorporeal shock wave lothotropsy, percutaneous nephrodtomy, Double-J stent insertion or ureterolithotomy. We suggest that extracorporeal shock wave lithotripsy monotheraphy with the Domestic SDS-2 lithotriptor was considered to be effective and safe procedure for the initial treatment of urinary stones.
