A new method of lithotripsy combining high and low frequency ultrasound has been investigated. This method controls generation of cavitation only on the stone surface and utilizes collapse pressure of the bubbles. In order to apply this method for clinical practice, it is important to monitor the process of stone crushing and behavior of cavitation from outside the body.
