目的　研究人体3种胆结石在一定能量下，冲击次数和能量的关系，确定不损伤胆囊和小肠内膜的能量安全阈值. 方法　犬胆囊和小肠内放入固醇石、混合石和色素石，在不同的输出电压下，放电碎石. 结果　固醇石、混合石和色素石破碎所需的能量不同，在同样电压下，固醇石所需的次数最少，混合石次之，色素石最多；病理检查表明，在电压<15 kV时，胆囊和小肠粘膜处，细胞膜轻度充血，出现小出血点. 当电压>15 kV后，粘膜有脱落，膜下组织水肿. 结论　电压具有依赖性；该仪器临床应用的冲击电压应小于15 kV.
목적　연구인체3충담결석재일정능량하，충격차수화능량적관계，학정불손상담낭화소장내막적능량안전역치. 방법　견담낭화소장내방입고순석、혼합석화색소석，재불동적수출전압하，방전쇄석. 결과　고순석、혼합석화색소석파쇄소수적능량불동，재동양전압하，고순석소수적차수최소，혼합석차지，색소석최다；병리검사표명，재전압<15 kV시，담낭화소장점막처，세포막경도충혈，출현소출혈점. 당전압>15 kV후，점막유탈락，막하조직수종. 결론　전압구유의뢰성；해의기림상응용적충격전압응소우15 kV.
AIM　To study the effect of shock wave on sterol stone, combination calculus and pigment stone and determine the threshold which can make them fragmentation without tissue damage. METHODS　The stones were put in the small intestine and gallbladder of canine and different voltages were used to shock them by discharge. RESULTS　There were different effects of shock wave on the three kinds of stones. At the same voltage in order to crush the stone the least times is needed for sterol stone, and then combination calculus, the times needed for pigment stone was the most. Pathological study showed that 15 kV voltage could be the threshold value which might damage the small intestine and gallbladder. CONCLUSION　There is dependence of energy on stones. The voltage used in clinic should be less than 15 kV.
