EDAP LT-O1 PLUSを用いた体外衝撃波による腎・尿管結石破砕術の治療経験

Abstract

37名の上部尿路結石症患者の37部位の結石に対しESWLを行い, 治療終了後1ヵ月目の時点における総合有用度判定の結果で, "きわめて有用"あるいは"有用"と判定されたのが合わせて27例あり, 重篤な副作用や合併症を生じた症例はなかったことより, EDAP LT-01 PLUSはESWL治療機器として有用なものであると判定した

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.
