Move it along: Ultrasound to rid kidney stones sans surgery

UW Health Sciences NewsBeat,

12 Jan 2016

Every year, more than a half-million people in the United States go to the emergency room for kidney stones. The common condition leads to hundreds of thousands of surgeries each year. Two new technologies developed by University of Washington researchers could bring noninvasive relief to such patients.
