リソクラストによる内視鏡的尿路結石破砕

Abstract

20例の尿路結石症例(尿管結石11例, 膀胱結石5例, コックパウチ4例)に対しリソクラスト(R)を用い砕石を試みた。自排可能までの破砕効果は90%, 1ヵ月後の無結石率は83%で, わずかの結石遺残を有効にいれると有効率は90%であった

We present our experience with a new and unique device for performing intracorporeal lithotripsy known as the Swiss Lithoclast. This simple device uses compressed air to activate a solid probe in a manner of a jackhammer. This device was used to treat 20 patients with stones in the ureter (11), bladder (5) or a Kock pouch (4). The Lithoclast successfully fragmented 90% of the calculi independent of the composition and salvaged 2 failed ESWL treatments. At one month after the procedure, either alone or in combination of with ESWL, 17 of 20 patients became free of stones. There were no complications related to use of the device. We have found the Swiss Lithoclast to be a safe and effective means of performing intracorporeal lithotripsy for urinary calculi.
