Hello,I have not heard of stone in
liver , See if its stone in gall bladder called cholelithiasis .
Extracorporial lithotripsy - A device that generates shock waves is used to break gallstones up into tiny pieces.Its used along with ERCP . For multiple stones in gall bladder cholecystitis is the best option. It can be done with laparoscopy or laparotomy .medicines are also used to dissolve stone but it takes very long time. Consult surgeon for more details .
