緒言

　昨年，経皮的腎尿管切石術を施行した5症例を中心に手技上の問題点を本誌に発表したが^1），今回はさらに迅速化，簡易化され，確実性を増した現在われわれの行つている方法について要点のみを述べてみたいと思う。

Utilization of safety guide wire, dilator (up to 36 Fr), Mazzariello-Caprini forceps and personal device of cold knife with 22 Fr urethrotome markedly improved successful rate of our present series of percutaneous nephroureterolithotomy cases. For the latest 4 cases of upper ureteral calculi and 10 cases of renal calculi, we made 100% successful rate, although small residual calculi were observed in 2 cases of huge staghorn calculi.
