Can a salt substitute save your kidneys after tumor surgery?
NCT ID NCT07062952
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether using a low-sodium, potassium-enriched salt substitute instead of regular salt can help protect kidney function in people who have had surgery for a kidney tumor. Two hundred adults who had a partial or full kidney removal will either use the salt substitute or regular salt for one year, following WHO salt guidelines. Researchers will measure kidney function and check for side effects.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
potassium-enriched low-sodium salt substitute
What this could lead to
If it works, this could offer a simple dietary way to help preserve kidney function after kidney tumor surgery.
What could go wrong
This is a small, early-stage study with only 200 people. The salt substitute may not improve kidney function and could cause side effects like high potassium levels.
