New ultrasound technique could prevent unnecessary treatments in pregnant women with kidney swelling
NCT ID NCT07547891
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether a special ultrasound technique called shear wave elastography can help doctors tell the difference between normal kidney swelling during pregnancy and swelling caused by a blockage that needs treatment. Researchers will measure kidney stiffness in 250 pregnant women with kidney swelling. The goal is to find a safe, non-invasive way to improve diagnosis and guide care.
