extracorporeal shock-wave lithotriptor

extracorporeal shock-wave lithotriptor

A device used to fragment calcified objects within the body, such as kidney stones. After the patient is given analgesics and anesthetic drugs, electrically generated shock waves are focused on the object in an attempt to disrupt it. In the case of kidney stones and gallstones, the stone fragments may subsequently pass either into the urine or the bile.
