Extracorporeal Shock Wave Lithotripsy (ESWL)

h9991424_001.jpg

Extracorporeal shock wave lithotripsy (ESWL) uses shock waves to break a kidney stone into small pieces. These pieces can more easily move through the urinary tract and pass from the body.

For this procedure you lie on a water-filled cushion. X-rays or ultrasound tests are used to locate the stone. High-energy sound waves pass through your body without injuring it and break the stone into small pieces.
