The life expectancy of chronic renal failure patients can generally range from a few years to several decades. After active and standardized treatment, the survival period of patients is longer and can last for several decades; if the disease is not treated actively and standardized, the condition can progress rapidly and death can be expected within a few years. Due to individual differences, the specific survival period is closely related to the severity of the disease, the individual’s physical condition and the effect of treatment. 1. Seriousness of the disease: chronic renal failure is easy to induce various complications and comorbidities, easily affecting the life and health of the patients, such as the serious condition, the disease can deteriorate rapidly and die within a few years; if the active standardized treatment, it will slightly slow down the process of the disease, and some of the patients can survive more than ten years. 2. Individual physique: the individual physique of the patient will also affect the life span, if the patient’s physique is poor, it is relatively easy to cause comorbidities and complications, and the life span will be shortened accordingly, and some patients can survive for several years, and some patients can survive for decades. 3. Treatment effect: Chronic renal failure can often achieve good treatment effect if standardized treatment is given early. If the best treatment time is missed, it will lead to aggravation of the condition, thus affecting the treatment effect, so the survival time of the patients can range from a few years to a few decades. It is recommended that patients with chronic renal failure should consult a doctor in time and follow the doctor’s instructions to avoid delaying the condition.
