How long can someone live with renal artery stenosis?

The survival time of patients with renal artery stenosis varies among individuals and cannot be generalized. It mainly depends on the severity of the renal artery stenosis and the patient's overall physical condition. 1. Mild or unilateral stenosis: If the degree of renal artery stenosis is mild or affects only one kidney, and the other kidney can compensate normally, the patient's survival time may not differ significantly from that of the general population. 2. Bilateral severe stenosis: If both renal arteries are severely narrowed, resulting in significantly reduced blood flow and accompanied by symptoms such as renovascular hypertension, serious complications such as cerebral hemorrhage may develop if left untreated. In such cases, the patient's survival time may be significantly shortened, although the exact duration varies among individuals and could be a few years. 3. Timely treatment: If the condition is detected early and effectively treated—for example, through surgical intervention to restore normal blood pressure—the patient's survival time may be significantly prolonged, potentially up to 10 years or longer.
