- Crushing Kidney Stones With Ultrasound
Extracorporeal shock wave lithotripsy (ESWL) is a procedure used to shatter simple stones in the kidney or upper urinary tract. Ultrasonic waves are passed through the body until they strike the dense stones. Pulses of sonic waves pulverize the stones, which are then more easily passed through the ureter and out of the body in the urine ...

Lithotripsy, a greek word that means "stone crushing", is a technique that uses focused energy waves to break apart kidney stones without damaging nearby tissue. Lithotripsy utilizes a medical device called a lithotripter to generate energy in a targeted manner to disintegrate kidney stones so that they can pass easily out of the body.
