There is no authoritative data to show how many years a relative kidney transplant can live, if the prognosis of the patient’s relative kidney transplant is good, he/she can usually live for about 10 years, and some of them can even live up to 20~30 years or even longer, if the patient suffers from rejection or other serious complications after the kidney transplant, he/she can only live for about 3 months or even shorter. Kidney transplantation is to transplant a healthy kidney to a patient who suffers from kidney disease and has lost kidney function. Due to individual differences, it is not possible to generalize how long a relative can live after a kidney transplant. How long a patient can live after the operation is related to many factors such as the patient’s physical condition, post-operative care and rejection of the transplanted kidney, etc., and the survival time after the operation varies greatly. If a relative gives a kidney transplant to a patient, there is no obvious rejection reaction after the operation, and the kidney function is normal after the operation, the patient can usually live for about 10 years. If the prognosis of some patients after kidney transplantation from relatives is poor, or rejection reaction occurs, they may only survive for about 3 months. The above time is for reference only. After undergoing kidney transplantation, you need to consult a doctor for examination, and the doctor will judge how many years you can live according to the patient’s physical condition. For patients who have undergone kidney transplantation, it is recommended to choose a regular hospital and go to the hospital for regular checkups after the operation.
