Understanding the Condition
Renal artery stenosis occurs when the arteries that supply blood to your kidneys become narrowed. When this happens to both kidneys, it's called bilateral stenosis. This condition is often linked to high blood pressure and can cause your kidneys to function poorly, increasing your risk for heart and kidney issues.
Causes and Risk Factors
The main causes of bilateral renal artery stenosis are atherosclerosis and fibromuscular dysplasia. Atherosclerosis is a condition where the arteries harden and narrow due to plaque buildup, often affecting people over 45. On the other hand, fibromuscular dysplasia is more common in women under 50 and affects the artery walls, causing them to twist or narrow.
Signs and Symptoms
Bilateral renal artery stenosis can present several noticeable symptoms. These include high blood pressure that's hard to control, sudden swelling in the legs, or even symptoms of heart failure. In some cases, the condition could lead to a rapid decline in kidney function, marked by an increase in creatinine levels in the blood.
