Extracorporeal shock wave lithotripsy (ESWL)

Extracorporeal shock wave lithotripsy (ESWL) essentially involves the use of X-rays or ultrasound to locate the position of the kidney stone. The machine sends out shock waves of energy which disintegrates the stone into smaller pieces so that it can be flushed out in your urine.
