33症例の上部尿路結石患者にアメリカ製Biolithos MARK 3を用いてESWLの臨床治験を行った。治療後1ヵ月目の効果判定では,有効率は72.7%でありほぼ満足のいく結果がえられた。特に問題となるような副作用・合併症もなく外来通院・無麻酔・鎮痛剤の投与なしでもESWL施行が可能であったThe results of clinical use of an extracorporeal shock wave lithotripter (Biolithos MARK III) are presented. From May 1991 through February 1992, a total of 50 sessions were carried out on 33 patients with upper urinary tract stones. Treatments were performed on an outpatient basis, and none of the patients needed anesthesia or analgesia. One month after the last session, 18 patients (54.5%) were free from stone fragments and 6 (18.2%) had stone fragments equal to or smaller than 4 mm. The over-all successful rate obtained by these categories was 72.7%. After treatment no serious complications were observed. Although gross hematuria appeared in almost all patients, pain was noted in only 5 patients. Laboratory data after treatments showed slight and transient changes. It is concluded that Biolithos MARK III is useful and safe in the management of upper urinary tract stones on an outpatient basis.
