In general, the survival of kidney transplant patients is around 10-20 years, but there are individual differences in the exact time. At present, the success rate of kidney transplantation is high. The survival period of kidney transplant patients is related to factors such as the patient’s preoperative physical condition, mating and postoperative drug tolerance and rejection after transplantation of kidney. If kidney transplant patients have no obvious rejection reaction after surgery, normal kidney function, timely review according to doctor’s orders and adequate monitoring of the functional status of the transplanted kidney, patients can obtain a longer survival period. For patients with poor mating or large rejection reactions after kidney transplantation, it is easy to cause complications, which can greatly affect the survival and quality of life of patients, and some patients even need 2 kidney transplants. Patients are advised to maintain an optimistic attitude, control their diet under the guidance of doctors, reduce the intake of high-salt and high-fat foods, reduce the stress on the kidneys, and regularly review and monitor the status of the transplanted kidney at all times to obtain long-term survival benefits.
