RESUMO
Two hundred sixteen patients with symptomatic urinary calculi underwent extracorporeal shock wave lithotripsy utilizing Therasonic Lithotripsy System (Theratonic LT -1000) at Kyunepook National Universily Hospital from April 1991 to march 1992. About 95.O per cent of stones were completely treated with one to nine session. The stone-free rate for patients with renal, upper and lower ureteral calculi was 93.9, 94.4 and 97.8 per cent respectively. Stone-free rate for individual patient depended on stone size. location. composition. and quality of disintegration. Postextracorporeal shock wave lithotripsy complications were minimal, these were gross hematuria. fever. flank pain, gastrointestinal trouble and stein strasse. Combined therapy utilizing percutaneous surgery or multiple sequential ESWL treatments is necessary for complex stones. In our opinion. ESWL utilizing Therasonic Lithotripsy System is more safe and effective treatment modality for urinary calculi except midureter and bladder than others.
