体外冲击波碎石经过12年实验与发展,1980年在联邦德国慕尼黑开始临床应用体外冲击波碎石。此种技术事实上有好处,冲击波作用于一椭圆体的焦点,集中于椭圆体的第二个焦点,并且这些冲击波通过液体传导体并通过软组织可以安全传导。有肾结石的病人用两个X-线光束在直角上定位,并且应用X-线监控病人的动作,结石定位在第二聚焦点。冲击波可以击碎大多数的肾结石成小碎片,然后在随后几天或几星期经输尿管排出。病人需要全麻或区域麻醉,而排出结石碎片的过程可能在1周至10天内完成,但最长有达3个月的。 Chaussy等报道>1000病例其中大约50%有肾绞痛,全部成功率达90%。体外冲击波碎石近来在德
Extracorporeal shock wave lithotripsy after 12 years of experimental and development, 1980 in Germany, Germany, began clinical use of extracorporeal shock wave lithotripsy. This technique is actually advantageous in that the shock waves act on the focal point of an ellipsoid focused on the second focal point of the ellipsoid and these shock waves pass through the liquid conductor and are safely conducted through the soft tissue. Patients with kidney stones were positioned at right angles with two x-ray beams, and the patient’s motion was monitored using an x-ray. The stones were positioned at the second focus. Shockwave can break most of the kidney stones into small pieces, which are then discharged through the ureters in the next few days or weeks. Patients require general anesthesia or regional anesthesia, and the process of removing debris from the stone may be completed within a week to 10 days, but up to a maximum of 3 months. Chaussy et al. Reported that> 50% of the 1000 cases had renal colic and the overall success rate was 90%. Extracorporeal shock wave lithotripsy was recently performed in Germany
