Focused Ultrasound for Kidney Stones

In an effort that is being led by Dr. Larry Crum, a member of the Foundation’s Research Advisory Committee, a new technique is being developed to use focused ultrasound to position kidney stones into better placement so that the body can pass them.

“We have a diagnostic ultrasound machine that has enhanced capability to image kidney stones in the body,” said Dr. Michael Bailey, a principal engineer at APL-UW and co-investigator on the project. “We also have a capability that uses ultrasound waves coming right through the skin to push small stones or pieces of stones toward the exit of the kidney, so they will naturally pass, avoiding surgery.”
