ESWLによる尿路結石の外来治療経験

Abstract

対象は1989年4月～12月の間に本法による治療を終了した78症例83結石である.18～77歳(平均48.5歳), 結石の部位は腎45例・上部尿管26例・下部尿管12例であった.外来でESWLを行うには2 cm以下, 腎・上部尿管・膀胱近傍の下部尿管が適当で, 2 cm以上の結石・push upを必要とする中, 下部尿管のもの・感染を伴うものには限界がある.腎に対する損傷を極力少なくするために周波数を2.5 Hzとし, 出力も制限している

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.
