INTERIM RESULTS OF ULTRASOUND TO REPOSITION SYMPTOMATIC URETERAL STONES
The Journal of Urology(2020)
Abstract
INTRODUCTION AND OBJECTIVE:This NASA funded study examines the ability of ultrasonic propulsion to dislodge and reposition acute obstructing ureteral stones from the ureteropelvic junction (UPJ) or the ureterovesical junction (UVJ) to relieve pain and obstruction, and/or to facilitate passage. Noninvasive manipulation of obstructing ureteral stones at the bedside would represent a breakthrough in the management of acute renal colic.METHODS:This is a 20-subject feasibility trial (NCT02028559). Patients presenting to either of two University of Washington Emergency Departments (ED) with an acute obstructing UPJ or UVJ stone are screened for inclusion. Standard of care is not interrupted. Once consented, participants undergo a pain assessment and the investigative procedure using a custom device capable of delivering ultrasonic propulsion for repositioning and burst wave lithotripsy (BWL) for …
