What's New?

CIMU Researchers and UW Radiology are exploring how to treat abscesses non-invasively using high-intensity focused ultrasound (HIFU). This experimental therapy could reduce pain, radiation exposure, antibiotic use, and costs for patients with abscesses. Therapeutic ultrasound could also treat abscesses too small or inaccessible for conventional drainage. More >>

Urologists and their patients from a first-in-humans clinical trial to reposition kidney stones with ultrasound envision the future benefits of the technology. More >>

NASA-funded UW researchers develop kidney-stone zapping technology


4 Jul 2016

With help from a grant from the National Space Biomedical Research Institute (a NASA-funded group), the team is developing a handheld ultrasound device that can detect and pulverize kidney stones — without surgery or bulky equipment.

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.

Expelling stones with ultrasonic propulsion

Nature Reviews Urology,

17 Nov 2015

Ultrasonic propulsion can be used to reposition kidney stones and facilitate the passage of stone fragments, according to a new study.
