In November 1991, a third generation extracorporeal shock wave lithotriptor (Piezolith 2500) was installed in our clinic. We examined the effective and safe aspect of this machine for @entity1791 . From November 1991 to October 1993, we experienced 530 sessions of ESWL treatment on 235 @entity1 (270 cases). All @entity1 except two underwent ESWL treatment without anesthesia, and in situ ESWL treatment was possible on 247 cases. The mean number of shock waves and sessions per @entity1 of @entity1290 were 3369 and 2.1, respectively. Those of ureteral stone were 3970 and 1.9, respectively. The complete removal rate of @entity1290 3 months after the last session were 86% and 92%, respectively. This outcome was very satisfactory. On the other hand, endoscopic procedure was needed on 13 @entity1 . In almost all cases @entity811 was noted after ESWL, but major complications such as subcapsular @entity1410 or @entity360 were not experienced at all. It was concluded that Piezolith 2500 was very effective and safe in the treatment of @entity1791 .
