ESWLの諸問題

Abstract

今日ESWLが腎尿管結石治療の中心的役割を果すようになった要因として, 第二・第三世代の装置の開発と, endourologyのバックアップにより, 治療適応の範囲が拡大されたこと, さらに衝撃波を節約して合併症を極力おさえ, 術後のstone streetへの対処がスムーズに行えるようになったことが考えられる

The pitfall of extracorporeal shock-wave lithotripsy (ESWL), such as complications of ESWL, problems of focus and results of stone disintegration are discussed. The progress of ESWL today is mainly due to the development of new generation lithotripters and endourological support, which has broadened the indications of ESWL. The necessary shock-waves have been selected, and complications have been reduced. Post ESWL stone street is now easier to treat. We expect more improved lithotripters such as by incorporation of X-ray and echo focusing systems. Endourological techniques including laser lithotripsy also should be improved.
