[Outpatient treatment with extracorporeal lithotriptor for renal and ureteral stones].

Between April 1989 and December 1989, extracorporeal shock wave lithotripsy (ESWL) was performed on 78 outpatients using the EDAP LT-01 device without anesthesia. The locations of total 83 stones were renal pelvis and calyx (45), upper ureter (26) and lower ureter (12). Of the cases with renal stones, 28 (62%) were free of stones, and 8 (18%) had fragments 4 mm in size or less. The over-all successful rate obtained by combining these categories were 80% in renal stones, 81% in upper ureteral stones, and 92% in lower ureteral stones. As complications, gross hematuria, pain which required analgesics, fever of 38 degrees C or higher and vomiting were seen. However, no serious complications were observed.
