How long is the life expectancy for elderly patients with chronic renal failure?

The life expectancy of elderly patients with chronic renal failure is influenced by multiple factors, including the patient's age, baseline kidney function, presence of complications such as cardiovascular disease, treatment status, and lifestyle. Therefore, it is not possible to provide an exact life expectancy prediction.

For patients who do not choose dialysis treatment, the expected lifespan is usually shorter. Elderly patients with mild to moderate kidney insufficiency can maintain a relatively good quality of life for several years if other health conditions such as hypertension and diabetes are actively managed. However, once the condition progresses to end-stage renal disease, the average survival time for patients not undergoing dialysis may be only about one year.

Elderly individuals often have complex overall health conditions and may suffer from other chronic diseases such as hypertension, diabetes, and heart disease. The presence of these conditions increases the difficulty of treatment and the risk of complications, thus affecting the patient's survival time. If the patient has good cardiac function, no severe complications such as hypertension or cerebral hemorrhage, and is able to consistently undergo treatments such as dialysis, their survival period may be relatively longer.
