Which diuretic protects a new kidney best? a Head-to-Head trial puts furosemide and mannitol to the test
NCT ID NCT07726134
First seen Jul 24, 2026 · Last updated Sep 18, 2026 · Updated 1 time
Summary
This trial compares two common diuretics—furosemide and mannitol—given during kidney transplant surgery to see which better prevents delayed graft function, a condition where the new kidney does not work right away and requires dialysis. The study enrolls adults receiving a deceased-donor kidney transplant. It aims to gather feasibility data and early signals on which drug may reduce complications and improve recovery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- furosemide or mannitol given intravenously during kidney transplant surgery
- What this could lead to
- If one drug proves better, it could reduce the need for dialysis after kidney transplant and improve long-term graft survival.
- What could go wrong
- This is a small pilot study focused on feasibility, not definitive results. The two drugs may turn out to be equally effective, or neither may show a clear advantage.
