Paper Abstract

There is considerable interest in methods of dealing with gallstones that would be less invasive than traditional gallbladder surgery. Our group has been especially interested in percutaneous endoscopic or transcatheter methods for performing biliary lithotripsy. We performed an in vitro comparison of three methods for lithotripsy, the thulium-holmium-chromium:YAG laser (THC:YAG), the ultrasonic lithotriptor (UL) and the electrohydraulic lithotriptor (EHL). We concluded that no one modality is clearly superior to the others, but rather that these methods are complementary with each modality having a preferred role.
