Lithotripsy
Lithotripsy is a non-invasive procedure (operation or treatment) used to break up unwanted hard objects in the body such as kidney stones, stomach stones (called bezoars) or gallstones (which are stones in the gall bladder.) Non-invasive means the doctor does not have to cut the person's body open to do the procedure. That does not mean that the treatment is not dangerous. It is somewhat dangerous. A lot of energy is required to break up stones. The treatment usually makes the person hurt (feel sore or bruised) for at least several days. Sometimes it causes bleeding inside the body.
