About Renal Artery Stenosis (RAS)
Renal Artery Stenosis (RAS) is the narrowing of one or both arteries that supply blood to the kidneys. This condition reduces blood flow, causing the kidneys to trigger high blood pressure (renovascular hypertension) and potentially leading to chronic kidney disease if left untreated.
At Paras Hospital, Patna, we offer comprehensive care for RAS—from diagnosis to advanced treatments such as renal angioplasty, stenting, and blood pressure control under the supervision of leading nephrologists and vascular specialists.

Common Causes of Renal Artery Stenosis
-
Atherosclerosis (plaque buildup in arteries)
-
Fibromuscular Dysplasia (FMD) – more common in younger women
-
High cholesterol or diabetes
-
Smoking and vascular disease
-
Genetic predisposition to artery narrowing
Symptoms of Renal Artery Stenosis
Many cases go undiagnosed until complications arise. Common signs include:
-
High blood pressure that is difficult to control
-
Sudden worsening of kidney function
-
Blood in urine
-
Swelling in ankles or legs
-
Flank pain or abdominal bruit (abnormal sound)
-
Recurrent fluid overload or shortness of breath (flash pulmonary edema)
Renal Artery Stenosis Diagnosis at Paras Hospital, Patna
Early diagnosis is crucial to prevent kidney damage. We offer the following tests:
-
Renal Doppler Ultrasound to assess blood flow
-
CT Angiography (CTA) and MR Angiography (MRA) to visualize artery narrowing
-
Renal Arteriography – a detailed catheter-based imaging test
-
Serum Creatinine, BUN, and eGFR to evaluate kidney function
-
Blood pressure monitoring and urinalysis
Treatment Options for Renal Artery Stenosis
Our treatment approach depends on the severity and cause of the stenosis:
Medical Management
-
Anti-hypertensive medications (ACE inhibitors, ARBs, diuretics)
-
Cholesterol-lowering drugs (statins)
-
Blood sugar control if diabetic
-
Lifestyle changes: low-salt diet, smoking cessation, weight loss
Interventional Treatments
-
Renal Angioplasty with or without Stenting: A catheter-based procedure to open the narrowed artery and improve kidney blood flow
-
Renal Artery Stent Placement for long-term relief from obstruction
-
Renal Bypass Surgery (rare, in selected complex cases)
Who Should Consider RAS Treatment?
Seek evaluation if you have:
-
Uncontrolled or resistant hypertension
-
Sudden decline in kidney function
-
Fluctuating creatinine levels or reduced urine output
-
History of cardiovascular disease and kidney issues
-
High BP despite being on 3 or more medications
