A urine test to monitor kidney health during hard-to-treat high blood pressure
Building a kidney monitoring panel to guide therapy in resistant hypertension
A urine-based kidney tubule health panel is being tested to help adults with resistant high blood pressure and kidney test changes stay on effective blood pressure medicines.

What this research studies
You would give urine samples while doctors adjust blood pressure medicines so researchers can measure specific kidney tubule biomarkers. The team will compare those urine biomarkers with changes in creatinine and blood pressure response over time. The goal is to tell when creatinine rises reflect true acute kidney injury versus harmless hemodynamic changes. If the panel works, it could help doctors avoid stopping medicines that protect the heart and kidneys.
Who could benefit from this research
Good fit: Adults (21+) with resistant hypertension—blood pressure uncontrolled despite three or more antihypertensive drugs—or people with renal artery stenosis who experience creatinine changes during treatment.
Not a fit: People without hypertension, those whose blood pressure is controlled on fewer than three medications, or patients with confirmed acute kidney injury needing immediate treatment may not benefit from this approach.
Why it matters
Potential benefit: If successful, this urine test could help clinicians distinguish true kidney injury from benign creatinine changes so patients can remain on effective blood pressure therapy that lowers cardiovascular risk.
How similar studies have performed: Prior studies have identified urine biomarkers of tubular injury, but applying a combined tubule health panel specifically to guide treatment in resistant hypertension is relatively new.
