中・下部尿管結石に対するESWL : 単一結石190例の上部尿管結石治療成績との比較

Abstract

1986年4月～1993年3月の間に中部尿管単一結石71例, 下部尿管単一結石119例に238回ESWLを行った。ESWL単独による最終的完全排石率は, 上部, 中部, 及び下部単一結石症例に於いてそれぞれ91.9%, 86.2%, 及び85.2%であった

We analyzed the results of treatment with extracorporeal shock wave lithotripsy (ESWL) (Dornier HM-3) for middle and lower ureteral solitary stones from April 1986 to March 1993 in our hospital. A total of 238 sessions of ESWL were done for 71 cases of middle ureteral stones and 119 cases of lower ureteral stones. The findings were compared with those obtained on the upper ureteral solitary stones. The final stone-free rate of the upper ureteral stones by ESWL alone were 91.9%, whereas those of middle and lower ureteral stones were 86.2% and 85.2%. We conclude that ESWL is equally useful for middle and lower ureteral stones to upper ureteral stones.
