Renal Angioplasty

Renal angioplasty is a medical procedure used to treat narrowing or blockages in the renal arteries, which supply blood to the kidneys. During the procedure, a doctor inserts a thin tube called a catheter into the blood vessel and threads it to the affected area. A small balloon at the end of the catheter is then inflated to widen the narrowed artery, improving blood flow to the kidneys. This can help manage conditions like high blood pressure and kidney disease. Sometimes, a stent—a small mesh tube—is placed to keep the artery open after the balloon is removed.
