Could a simple ultrasound replace radiation scans for kidney blockages?
NCT ID NCT05090800
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a special ultrasound with a contrast dye (Definity) can detect kidney obstructions. Ten adults with a blocked kidney had ultrasound scans before and after surgery to relieve the blockage. The goal was to see if this method works as well as standard nuclear scans, but without radiation.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Definity contrast agent (Perflutren Lipid Microsphere)
- What this could lead to
- If successful, this could provide a safer, radiation-free way to diagnose kidney obstructions using ultrasound instead of nuclear scans.
- What could go wrong
- This is a very small, early-phase study with only 10 participants, so results may not apply to everyone. The technique is still experimental for this use.
