Endovascular treatment of renal artery stenosis is a procedure used to treat narrowing of the renal arteries, which supply blood to the kidneys. The procedure typically involves inserting a catheter through the groin and using angioplasty or stenting to widen the affected artery and restore normal blood flow to the kidneys.

This procedure is essential for preventing kidney damage, hypertension, and other complications associated with renal artery stenosis.
