Laser therapy for bile duct stones, such as the non-contact beam treatment using continuous wave of Nd : YAG laser or contact beam treatment using ceramics rod, has been done in our institution from 1980. As a result, the ratio of complete lithotomy has been increased from 31/47 (66％) to 66/71 (93％). Recentry, we had a opportunity to use the Lasertripter by Candera Corp., which was deviced for urinary stones. It beams pulse wave to crush stones. The effectiveness of this new laser lithotripsy is different according to the kind of the stones, but it is better than that of conventinal YAG laser. Furthermore, as this method can be used with thin fiberscope, this method is more effective to peripheral intrahepatic stones than YAG laser.
