ultrasonic lithotripter
Quick Summary
An ultrasonic lithotripter is an instrument used to break up kidney stones. It employs focused ultrasound waves to disintegrate stones in the urinary tract, typically the kidney or upper ureter. The resulting fragments are then passed out of the body. This non-surgical method often involves immersing the patient in water or using a water-filled bulb to transmit the shock waves. In some cases, X-ray guidance is used to focus the ultrasound, or a small rod is inserted to deliver ultrasound in the 22- to 30-kilohertz range for endoscopic ultrasonic disintegration.12
