Betvveen January 1998 and January 1999, 137 patients with urinary stones underwent extracorporeal shock w a ve tithotripsy (ESWL) in our department. Effectiveness of the treatment was assessed with piain abdominal fi/ms and ultrasonography in necessary cases. Of 137 patients, eighty seven who were followed regularly were evaiuated retrospectively. Ninety one patients were male and 46 were fema/e with an overall mean age of 39.4 (range: 10-72). Of the evaiuated 87 cases, 34 were ureteral and 53 were renal stones. Median seance number was 1 (range: 1-4) with the mean shock number per each seance 2824 (range: 500-3500), the mean intensity of shock waves 18kV(range: 10-22) and mean stone surface being 0.98 cm2 (range. 0.20-2.28). Six of these patients did not continue the procedure due to intolerance. In six other cases, ESWL was unabie to clear the urinary stones completely. Due to faiiure of the treatment two other patients underwent open surgery and two had ureterorenoscopic procedure. The success rate of ESWL was found to be 87.6% (n: 71 patients) in the evaiuated 87 patients and from this point of view, Stoneiith-V3 ESWL instrument was found to be saf e and effective in the treatment of urinary stones.
