Overview
Renal Artery Stenosis
Renal artery stenosis is narrowing of one or both arteries that supply blood to the kidneys. Reduced blood flow can activate mechanisms that raise blood pressure and, in some cases, impair kidney function. The most common causes are atherosclerosis and fibromuscular dysplasia. Some people have no symptoms, while others develop difficult-to-control hypertension or declining kidney function.
Chronic Kidney Disease
Chronic kidney disease is a long-term condition in which the kidneys become damaged or lose function over time. Healthy kidneys remove waste and excess fluid from the blood and help regulate blood pressure, electrolytes, and other important processes. Chronic kidney disease may progress gradually and can eventually lead to kidney failure. Early disease may cause few or no noticeable symptoms.

Renal Artery Stenosis
Diagnosis involves assessing blood pressure, kidney function, cardiovascular risk factors, and features suggesting renovascular disease. Imaging may include Doppler ultrasound, CT angiography, or magnetic resonance angiography to evaluate renal arteries. In selected circumstances, catheter-based angiography provides detailed visualization. Testing is generally considered when renal artery narrowing is clinically suspected, particularly with difficult-to-control hypertension or unexplained deterioration in kidney function.
Chronic Kidney Disease
Diagnosis uses blood and urine tests to assess kidney function and look for evidence of kidney damage. Blood creatinine is used to estimate the glomerular filtration rate, while urine testing can detect albumin or other abnormalities. Blood pressure measurement and review of medical history are also important. Ultrasound or other imaging may help identify structural abnormalities, obstruction, or other causes. Additional testing may be required when the cause is uncertain.
Prevention
Renal Artery Stenosis
Atherosclerotic renal artery stenosis shares many risk factors with cardiovascular disease. Not smoking, maintaining healthy blood pressure and cholesterol levels, controlling diabetes, exercising regularly, maintaining a healthy weight, and following a heart-healthy diet can reduce vascular risk. People with established cardiovascular disease should follow recommended medical treatment and monitoring. Fibromuscular dysplasia cannot generally be prevented through lifestyle measures.
Chronic Kidney Disease
Not all chronic kidney disease can be prevented, but controlling conditions that damage the kidneys can reduce risk or slow progression. Maintain healthy blood pressure and blood glucose levels, avoid smoking, stay physically active, and maintain a healthy weight. Use medicines as directed and avoid unnecessary use of medicines that can harm the kidneys. People at increased risk should follow recommended kidney-function and urine testing and seek medical advice for persistent abnormalities.
Risk Factors
Renal Artery Stenosis
Risk factors for atherosclerotic renal artery stenosis include older age, smoking, high blood pressure, diabetes, high cholesterol, and other cardiovascular risk factors. Fibromuscular dysplasia is more often associated with women and may occur without the usual cardiovascular risk factors. A history of vascular disease elsewhere in the body can also increase the likelihood of renal artery narrowing.
Chronic Kidney Disease
Risk is increased by diabetes, high blood pressure, heart disease, obesity, older age, smoking, and a family history of kidney disease. Previous acute kidney injury and certain inherited or inflammatory kidney disorders can also increase risk. Long-term use of some medicines or exposure to kidney-toxic substances may contribute. Risk is particularly important when several of these factors occur together.
