Renal Angioplasty and Stenting
This is a treatment for patients with vascular disease that affects blood flow through the kidneys. A catheter (thin, flexible tube) with a balloon in its tip is inserted in the artery in the leg. X-ray helps the doctor thread the catheter into the renal artery that is obstructed. Next the balloon is inflated to push the plaque against the wall of the artery. A small wire mesh tube (stent) can then be inserted to keep the artery open, helping to improve blood flow.
