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.
