The treatment options for renal artery stenosis range from lifestyle changes and medication to minimally invasive procedures and surgery. The right path depends on the severity of your condition, your overall health, and how your kidneys are responding. A vascular specialist can help you understand what approach makes the most sense for you.
A diagnosis of renal artery stenosis can feel overwhelming. Your arteries are narrowed, your kidneys are under stress, and your blood pressure is difficult to control. The good news is that there are several effective treatment options for renal artery stenosis — and the right one for you depends on factors your care team will assess carefully.
Here is what you need to know.
Treatment Options for Renal Artery Stenosis
Treatment is tailored to each patient. If the narrowing is mild and your kidneys are still functioning well, close monitoring may be all that is needed. For more significant cases, your care team will likely recommend one or more of the approaches below.
What does medical management for renal artery stenosis involve?
Medical management is often the first line of care. It combines lifestyle changes with medication to lower blood pressure and slow any damage to the kidneys.
Lifestyle changes that help include:
- Reducing salt intake to ease fluid retention
- Maintaining a healthy weight to reduce pressure on the cardiovascular system
- Staying physically active to support blood vessel health
- Quitting smoking, which accelerates artery damage
Medications your doctor may prescribe include ACE inhibitors, angiotensin receptor blockers (ARBs), diuretics, calcium channel blockers, and beta blockers. If atherosclerosis is the underlying cause, cholesterol-lowering medications and aspirin are often added as well.
Medical management works well for many patients. It requires patience — finding the right combination of medications can take time — but it is a meaningful first step toward protecting your kidney function and controlling your blood pressure.
When is angioplasty with or without stenting recommended for renal artery stenosis?
When medication alone is not enough, a minimally invasive procedure called renal angioplasty may be recommended. During this procedure, a small balloon is used to widen the narrowed artery and restore blood flow to the kidney.
In many cases, a small mesh tube called a stent is placed inside the artery to keep it open. Stenting is particularly common when atherosclerosis is the cause of the narrowing. For patients whose RAS is caused by fibromuscular dysplasia (FMD), angioplasty alone — without a stent — often produces strong, lasting results.
This approach is typically considered for patients who do not respond well to medication, who cannot tolerate certain drugs, or who experience fluid retention or difficult-to-manage heart failure alongside their RAS.
What surgical options are available for renal artery stenosis?
Renal artery bypass surgery is reserved for cases where angioplasty has not been effective or where additional surgery is already being performed. During this procedure, a surgeon creates a new route for blood to travel to the kidneys, typically by connecting the renal artery to a vessel from the liver or spleen.
Surgery carries more recovery time than minimally invasive procedures, but for patients who need it, it can provide lasting relief and protect long-term kidney function.
