Extracorporeal shock wave lithotripsy (ESWL) uses shock waves to break a kidney stone into small pieces that can more easily travel through the urinary tract and pass from the body.
You lie on a water-filled cushion. X-rays or ultrasound tests are used to precisely locate the stone. High-energy sound waves pass through your body without injuring it and break the stone into small pieces.
