New ultrasound technique could spare kidney patients from biopsies

This study is testing a new ultrasound method to look at tiny blood vessels in the kidneys of people with nephritis (kidney inflammation). Researchers will use contrast-enhanced ultrasound and ultrasound localization microscopy to create detailed images of kidney blood flow. The goal is to see if this non-invasive technique can provide useful information about kidney damage, potentially reducing the need for invasive biopsies in the future. The study involves 30 adults with proteinuria or active urinary sediment who are already scheduled for a kidney biopsy.
