[Clinical experience with extracorporeal shock wave lithotripsy using Dornier MFL 5000-(U) for urinary stone].
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.
