Abstract

ESWL has been demonstrated to be a safe and efficacious means to treatment of urinary calculi. We report the results of 176 patients(203 cases) treated with EDAP LT-01 lithotriptor between January 24 1989 and August 24 1989. The patients were followed for over two months. The results were obtained as follows ; 1. The sex ratio was about 2.4: 1, 125(71.0%) in male and 51(29.0%) in female. The fifth decade(30.1%) was most, followed by fourth decade( 26.7 % ) and sixth decade(18.2%) 2. The stone location showed that kidney was 128 cases( 63.1% ) and ureter was 75 cases( 36.9%), The stone size showed that 94 cases(46.3%) in under 10mm, 75(36.9%) in 11-20mm and 34(16. 8%) in over 21mm. 3. The overall success rate(complete in 74.9% and partial in 23.6% ) was 98.5%. The complete success rate of 122 cases who treated with frequency of 10/sec. was 53.3 %, but 81 cases who treated with frequency of 5/sec. showed the complete success rate of 76.6%. 4. Adjunctive procedures after ESWL were performed 6(3%), including ureterolithotomy in 2(1.0%) and pyelolithotomy, PCNJ PCNL and URS in each 1 case(0.5% ). 5. Complications were showed that gross hematuria for over 1 day in 68.3%, nausea and vomiting in 26%, renal colic in 17.9% and ureteral obstruction in 8.9%. But, all patients re- covered with only conservative treatment except URS and PCN in each 1 case. 6. There were not statistically significant changes in level of BUN, Creatinine, SGOT, SGPT and Creatine phosphokinase, but S-amylase and LDH were significantlychanged(p <0.05).
