How long a patient can live with renal failure depends on the urgency of the disease and the effectiveness of treatment, which can be as short as a few weeks or as long as decades. Kidney failure can be clinically divided into acute renal failure and chronic renal failure. Some patients with acute renal failure may be cured with active clinical intervention, which usually does not affect the patient’s life expectancy. Alternatively, some patients can gradually develop chronic renal failure, and when it reaches the uremic stage, the kidney function must be replaced by dialysis therapy. If patients with chronic renal failure have a good basal status, most patients can survive for several years or even a dozen years after standard dialysis treatment. However, if the patient has other underlying diseases in combination with kidney failure, the survival time will be relatively shortened, and severe cases can even die within weeks. It is recommended that once a patient is diagnosed with renal failure, he or she should cooperate with the doctor as soon as possible to carry out standardized systemic Chinese and Western medicine treatment, and actively control diet and water intake under the guidance of the doctor.
