Renal stenting is a means of removing a blockage or constriction of the large blood vessels that feed the kidneys in order to ease the flow of blood to those organs. Such clogs may be caused by atherosclerosis or fibrous disease. The procedure is done via angioplasty, where a small catheter is threaded from the groin up to the narrowed part of the renal artery with the help of imaging equipment. A tiny balloon is next guided up through the catheter to that same location and inflated, thereby opening the blood vessel. A special mesh tube called a stent is then securely positioned to keep the artery open and allow for optimal blood flow. While this process doesn’t cure renal artery stenosis, it can help slow the disease’s progress.
