Summary

This study uses a dye called iohexol to measure how well the kidneys are working in patients leaving the intensive care unit after acute kidney failure. The goal is to find out how many patients still have reduced kidney function even though their standard blood tests look normal. The results could help doctors better understand who needs long-term follow-up for kidney health.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: iohexol (Omnipaque)
What this could lead to: If successful, this could help doctors better predict long-term kidney recovery in ICU survivors and guide follow-up care.
What could go wrong: This is a measurement study, not a treatment. It may not change outcomes directly, and iohexol clearance is not a standard test in all hospitals.
