title: [Clinical application of EDAP LT-01 PLUS on extracorporeal shock wave lithotripsy for urolithiasis].
abstract: With EDAP LT-01 PLUS, a new extracorporeal shock wave lithotriptor which generates shock waves by 320 ceramic elements activated by the piezoelectric effect and which was produced to be used for the treatments of both urolithiasis and gall bladder stones, we performed extracorporeal shock wave lithotripsy (ESWL) on 37 patients with urolithiasis between November 22, 1989 and July 31, 1990. Thirty seven target stones of 37 patients were located in the renal calyx (11 cases), renal pelvis (3 cases), UPJ (6 cases), renal calyx and pelvis (1 case), renal calyx and UPJ (1 case), renal calyx and upper ureter (1 case), upper ureter (9 cases), middle ureter (1 case), and lower ureter (4 cases). None of the patients needed anesthesia. The average number of treatments per case was 2.9 and the average total times of treatment per case was 196 minutes. The overall stone-free rate one month after the last ESWL treatment was 54.1% (20/37), and no patients had any major side-effects. Judging from our present clinical application, we concluded that EDAP LT-01 PLUS is a useful extracorporeal shock wave lithotriptor for urolithiasis.
