'Playing Pool' Is New Approach to Dislodge Kidney Stone Fragments
Ultrasound technology that moves small, lingering kidney stones toward the ureter to avert episodes of pain or additional surgery may be ready for US Food and Drug Administration (FDA) approval next year, researchers report. A 60-patient randomized clinical trial in progress at the University of Washington has produced encouraging findings from using focused ultrasound to dislodge persistent kidney stones left after surgery, said investigator Mathew Sorensen, MD, an associate professor of urology at the university.
