Summary

Atherosclerotic renal artery stenosis is the most common cause of secondary hypertension , increasing the risk of cardiovascular and kidney-related complications. Some small-scale studies have suggested that covered stents are effective and safe, but high-quality evidence from large-scale studies in atherosclerotic renal artery stenosis remains limited.

This study aims to evaluate whether covered stents are more effective than bare metal stents in patients with atherosclerotic renal artery stenosis. Eligible participants will be randomly assigned to receive either a covered stent or a bare metal stent. Patients will be followed for 12 months to assess Changes in eGFR, 24-hour systolic blood pressure, and 24-hour diastolic blood pressure from baseline to 12 months were compared among the groups.

The results of this study may help improve treatment strategies and guide the selection of stent type for patients with this condition.
