Stent vs. medication for narrowed kidney artery
Treatments studied
Part of Heart & circulation, Kidney & urinary clinical trials.
This trial compares placing a tiny mesh tube (stent) to open the narrowed kidney artery versus continuing blood pressure medicines alone. It is for people whose high blood pressure is hard to control even with multiple medications and who have a blockage in the kidney artery that can be treated.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have high blood pressure that stays high (daytime average ≥135/85) even with at least two different blood pressure pills.
- You are scheduled to have an angiogram of your kidney arteries.
- The angiogram shows a kidney artery with 50%–90% narrowing, and the artery is at least 4 mm wide.
- You have not had a stroke, mini-stroke, or major neck artery blockage recently.
- Your kidney is at least 8 cm long and you have not had a stent or surgery on the kidney artery before.

Other trials that look related to this one.
This trial tests whether placing a small metal tube (stent) in a narrowed kidney artery—guided by a pressure measurement called fractional flow reserve—helps lower blood pressure better than a placebo (no stent). It is for people whose blood pressure stays high despite taking multiple medicines.
This trial studies whether placing a small stent in a severely narrowed kidney artery can improve outcomes for people with high-risk, artery-hardening kidney blood-flow problems. It focuses on people whose high blood pressure or kidney function has been getting worse despite multiple medications.
This trial tests a new device that uses ultrasound to treat nerves in the kidney arteries that may be overactive and raising your blood pressure. It's for people whose blood pressure stays high despite taking at least two medications.
This study compares a drug-coated stent placed in a neck (vertebral) artery versus best medical treatment with medicines and risk-factor control. It aims to reduce problems caused by a badly narrowed artery after recent stroke-like symptoms.
This trial tests whether using a pressure wire to guide treatment of narrowed kidney arteries helps lower blood pressure better than usual care. It may help people with severe high blood pressure caused by kidney artery blockages.
This study compares two types of stents (a small mesh tube) placed in the kidney artery to open up a narrowed vessel. The goal is to see if a stent with a fabric cover works better than a bare metal stent for improving blood flow and controlling blood pressure.
