What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
covered stent (device) and bare metal stent (device)
What this could lead to
If covered stents prove better, this could become the preferred treatment for renal artery stenosis, helping control blood pressure and protect kidney function.
What could go wrong
This is a relatively small, early-stage study with only 150 participants, and results may not apply to all patients. Stent procedures carry risks like vessel damage or restenosis.
