Abstract

• Since extracorporeal shock waves lithotripsy in urinary tract has been proved successful, it leads to extend the technology to the treatment of gallstones. Before preliminary clinical application of extracorporeal shock wave lithotripsy for gall stone, I evaluated the effects of Extracorporeal SD-3 lithotripsy on the various abdominal organs of the dogs and its efficacy on experimentally induced cholelithiasis in the same species.
  In spite of a limited number of observation, the high energy shock wave was not serious complication of abdominal organs, and experimentally induced gall stone in the dogs seems to be effectively fragmented and tolerated in the composition of cholesterol stone, but not effect in pigment stone.
  In conclusion, the biliary lithotripsy with extracorporeal shock wave may be a useful treatmental method if applied in selected cases and it should be opened for further study in larger experimental group.
