Ultrasonic Lithotripsy

Ultrasonic Lithotripsy

The resultant ultrasonic waves are transmitted longitudinally through the sonotrode to the stone. In contact with the probe, the stone vibrates until it is fragmented. Placing the sonotrode in contact with the urothelium causes minimal lesions, due to the fact that the tissues do not resonate at the vibrating energy Grocela and Dretler, 1997). Although heating of the probe's .

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. See a picture of ESWL. You lie on a waterfilled cushion, and the surgeon uses Xrays or ultrasound tests to precisely loe the stone. Highenergy sound waves pass through your body without .

Move it along: Ultrasound to rid kidney stones sans ...

Bursting the stones Burst wave lithotripsy uses focused ultrasound to crumble stones into uniform, small fragments, allowing the stones to pass naturally. The idea originated from 20 years of research of shock wave lithotripsy, in which shock waves are used to break up kidney stones. Maxwell and Bailey found that short ultrasound pulses actually broke stones faster and into .

Purpose: Focused ultrasonic propulsion is a new noninvasive technique designed to move kidney stones and stone fragments out of the urinary collecting system. However, to our knowledge the extent of tissue injury associated with this technique is not known. We quantitated the amount of tissue injury produced by focused ultrasonic propulsion under simulated clinical treatment conditions and ...

Burst Wave Lithotripsy

Burst Wave Lithotripsy

Based on this work, we are now investigating an alternative noninvasive method to fragment stones by using ultrasound pulses rather than shock waves to fragment stones, called burst wave lithotripsy or BWL. Ultrasound bursts consist of consecutive acoustic cycles that can accumulate to concentrate energy within the stone, enabling comminution at relatively low .
