Clinical trials using Extracorporeal Shock Wave Lithotripter (Tripter X-1) were performed on 30 cases for upper urinary tract calculi (16 cases: renal stone, 14 cases: ureter stone) with one trial per individual case from December, 1988 till February 1989. The fragmentation rate of 100% resulted. One month after treatment, evaluation on the X-ray film showed that 10 cases (33%) were found to be excellent where stone silhouette was no more observed. Effective cases where residual stone having dimension of below 5mm counted 10 (33%), and clinically effective rate, sum of both excellent and effective rates was 67 percent. Effective rate was 75 percent in case of kidney stone, and 57 percent in case of ureter stone respectively. Side effects of visual hematuria, skin ecchymosis and fever were observed, yet none of them was of serious grade, and post operative changes in blood chemistry were mild and transient. No remarkable side effects due to radiation exposure were observed. We concluded therefore that Extracorporeal Shock Wave Lithotripsy by this system is an effective therapy for upper urinary tract stones.

Clinical trials of the third generation extracorporeal shock wave lithotriptor (TRIPTER X-1) on 30 patients with upper urinary tract calculi were performed from May to July, 1988. Eighteen patients (60%) were free from stones and 5 (16.7%) had stone fragments less than 5 mm, the effective rate of treatment which is sum of both group being 76.7 per cent, at one month after the treatment. The effective rate was 72.7 per cent for stones in the kidney and 87.5 per cent for those in the upper ureter. And the effective rate as to stone size was 100, 66.7 and 71.4 per cent, in stones less than 1 cm, 1 cm to less than 2 cm and 2 to 2.5 cm, respectively. Although gross hematuria skin ecchymosis, pain and fever were observed as side effects, none was serious enough to be mentioned. And post operative changes in blood chemistry were mild and transient. We confirmed extracorporeal shock wave lithotripsy using this machine for upper urinary tract stones is an effective treatment without any serious side effects.
