Ultrasound to Facilitate Stone Passage
Sponsor: University of Washington
Summary
This is a prospective, open-label, multi-center study to test the clinical feasibility of facilitating stone passage by the combination of breaking and repositioning stones with ultrasound, without the need for anesthesia.

Burst Wave Lithotripsy (BWL) and Ultrasonic Propulsion (UP)
Novel ultrasound technologies to facilitate passage of stones.This includes Burst Wave Lithotripsy (BWL), a technology to noninvasively fragment urinary calculi within the kidney and ureter, and ultrasonic propulsion, a technology to non-invasively reposition stones within the kidney and ureter. BWL uses short multi-cycle bursts of low amplitude ultrasound to induce stone fracture. This is in contrast to traditional extracorporeal shock wave lithotripsy (SWL), which employs a brief single compression/tensile cycle of high amplitude (shock) waves to achieve stone fracture. Ultrasonic propulsion uses long multi-cycle bursts of low amplitude ultrasound to move stones within the collecting system.
