Extracorporeal Shock Wave Lithotripsy is a noninvasive procedure used for the treatment of kidney stones. Usually this procedure is used for those stones that are too large to pass through the urinary tract. ESWL uses focused sound waves or ultrasonic energy which are generated by a machine called a lithotripter directly on the stones
