Dialysis for kidney disease is a commonly used alternative treatment for patients with renal failure and uremia, and is available in both hemodialysis and peritoneal dialysis. However, the exact length of time a patient on kidney disease dialysis can live varies from person to person. Kidney dialysis can effectively remove toxins from the body, reduce excess water in the body, and maintain the acid-base and electrolyte balance in the body. Generally, the survival period of dialysis is 5-10 years, but some patients may survive less than 1 year, while the longest survival can be up to 40 years. This is related to the patient’s underlying disease, residual renal function and complications caused by uremia, age, and whether the patient is on dialysis regularly. In addition, reasonable diet, prevention of cardiovascular diseases, active blood pressure control and regular follow-up can also help to prolong the survival cycle and improve the quality of life. At present, whether it is peritoneal dialysis or hemodialysis treatment, the survival cycle of patients is being extended, and patients must maintain an optimistic attitude and actively cooperate with treatment.
