Abstract

Microexplosion lithotripsy (MEL) was clinically developed for the destruction of urinary stones in our clinic in 1981. In MEL two kinds of blasting are available: external charge blasting and confined blasting. The detonation power of the latter is 3 times larger than that of the former. Up to July, 1986, microexplosion cystolithotripsy has been successfully performed on 100 cases. In the early stages only external charge blasting was used. It was, however, not easy to crush a big bladder stone over 5 cm in diameter. For that reason, confined blasting was newly developed and in 50 cases microexplosion cystolithotripsy using confined blasting was completed successfully. As the next step, percutaneous nephrolithotripsy using confined blasting has been successfully performed on 12 cases including 3 of staghorn calculi.

摘要

1981年，我们诊所临床研发了微爆破碎石术（MEL）用于尿路结石的粉碎。在微爆破碎石术中，有两种爆破方式：外装药爆破和聚能爆破。后者的起爆功率是前者的3倍。截至1986年7月，已成功对100例患者实施了微爆破膀胱碎石术。早期仅采用外装药爆破。然而，要粉碎直径超过5厘米的大膀胱结石并非易事。因此，新研发了聚能爆破，并成功完成了50例采用聚能爆破的微爆破膀胱碎石术。下一步，对包括3例鹿角形结石患者在内的12例患者成功实施了采用聚能爆破的经皮肾镜碎石术。
