尿路結石症 - その治療の変遷 - 尿路結石破砕法(特に微小発破について)

Abstract

Noninvasive therapy for urolithiasis such as percutaneous nephroureterolithotomy (PNL) has progressed rapidly during the last few years. Several kinds of non-mechanical disintegration methods such as electrohydraulic lithotripsy, ultrasound lithotripsy, stone disintegration by laser irradiation, electric drill disintegration, microexplosion lithotripsy and extracorporeal shock wave lithotripsy have contributed to this advancement. However, these methods are not without some problems, such as effect and technique. This paper describes the theory and effectiveness of these non-mechanical methods except extracorporeal shock wave lithotripsy, especially of microexplosion lithotripsy in detail.
