体外震波碎石术(ESWL)其主要原理是施于一定大小和形态的弹性波,而其强度应超过结石的弹力极限,使其击碎结石。早在1955年苏联液电解质内二电极之间放电而产生弹性脉冲取得专利。80年代以来,由于电子技术有了很大的发展,因此使碎石技术更为现代化,更精密和更可靠。 1982年西德Choussy等,首次报道“水中聚焦冲击波体外粉碎肾结石”的临床效果以来,体外震波碎石术引起了各国学者的广泛重视,并得到迅速发展,治疗效果越来越好。1985年以来我国也相继研制出类似的机器,近年来发
Extracorporeal shock wave lithotripsy (ESWL) its main principle is applied to a certain size and shape of elastic waves, and its strength should exceed the elastic limit of stones, making it crushed stone. As early as 1955, the Soviet Union liquid electrolyte discharged between the two electrodes to produce elastic pulse patented. Since 1980s, due to the great development of electronic technology, the gravel technology has become more modern, more precise and more reliable. In 1982, Choussy et al. First reported the clinical effect of “underwater focused shock wave crushed kidney stones in vitro”. Extracorporeal shock wave lithotripsy has drawn wide attention from scholars all over the world and has been rapidly developed. The therapeutic effect is getting better and better. Since 1985, China has also developed similar machines in succession in recent years
