Dornier MFL 5000-(U)による尿路結石の治療経験

Abstract

MFL-5000で治療し, 3ヵ月経過観察した40例について, 1)40例の尿路結石症に対し, 1ヵ月後の, 排石率は67.5%27例に完全排石を認め, 3ヵ月後には, 85.0% 34例に排石率は上昇した。2)40例に対し1例のみ硬膜外麻酔を行い, 無麻酔症例において疼痛を訴えた症例に対しては, 鎮痛剤の投与のみにて対処し, 十分に除痛効果をえられた。3)治療を必要とした重篤な副作用は認めなかった

Our hospital recently installed one of the newest types of extracorporeal shock wave lithotripters, a Dornier MFL 5000-(U). We conducted preliminary clinical trials with the apparatus from April to June 1991. In this report we discuss our experience with the first 40 patients (52 stones) treated in a total of 52 extracorporeal shock wave lithotripsy (ESWL) sessions. Follow up observation was conducted for three months. Except in one case, invasive anesthesia was not used. A double J-catheter was inserted in 13 cases, a ureteral catheter in 7 cases, and percutaneous nephrolithotripsy (PNL) was used after ESWL in one case. After one month of follow-up, 27 patients (67.5%) were completely free from stone fragments, while at 3 months after treatment, 34 patients (85.0%) were free from stone fragments. No serious complications were observed after ESWL. We concluded that the Dornier MFL-5000-(U) apparatus is effective for renal and ureteral stones and generates no serious complications.
