Abstract:
PURPOSE: We studied to evaluate the safety and effectiveness of the domestic SDS-3000(R) extracorporeal shock wave lithotriptor (SWL). MATERIALS AND METHODS: Between October 1995 and April 2000, 440 patients, 16 to 79 years old, were treated with the domestic SDS-3000(R) lithotriptor using C-arm fluoroscopy without regional or general anesthesia. Distribution of stones, location and size of stones, session, success rate, causes of failure and complications of SWL were retrospectively reviewed. RESULTS: Of 440 patients, renal stones were 133 (30.2%) and ureteral stones 307 (69.8%). The overall success rate (stone free rate) of SDS-3000(R) lithotriptor in 440 patients was 89.8% (81.4%) with 94.9% (91.0%) in 5-9mm, 87.2% (75.8%) in 10-19mm, 66.7% (42.8%) in 20-29mm and 57.1% (35.7%) over 30mm of stone size. The success rate was 94.9% for stones between 5-9mm in diameters and 82.6% for stones more than 10mm (p<0.05). As compaired with success rate for stones less then 20mm, stones more then 20mm had significently higher success rate (92.1% Vs 62.8%) (p<0.05). Ureter stones were more successfully treated than renal stones (93.2% Vs 82.0%) (p<0.05). Main complications of SWL were renal colic in 10.0%, steinstrasse in 4.3%, transient gross hematuria in 1.8% and fever in 1.1%. All of complications were controlled with conservative treatment. CONCLUSIONS: The domestic SDS-3000(R) lithotriptor monotherapy is considered to be a safe and efficient outpatient procedure for the initial treatment of urinary stones.
