Biliary lithotripsy with the Siemens Lithostar Plus overhead module.

A third shock head has been added to the Lithostar. This overhead module with integrated ultrasound complements the existing bilateral undertable shock heads with biplane x-ray amplifiers for stone targeting. Extracorporeal shock wave treatment of urinary tract stones, pancreatic stones, and stones in the gallbladder and bile ducts has thereby become possible in one true multipurpose lithotripter. Technical information and clinical experience in the biliary tract with the overhead module is presented.
