It takes about 300,000-400,000 RMB to replace a kidney, and the kidney replacement is mainly for patients with uremia. Uremia is the end stage of various kidney diseases, at this stage, the kidney function is completely lost, it cannot detoxify or drain, and the anemia is very obvious. A more ideal treatment is kidney transplantation, the transplanted kidney has all the functions of its own kidney, but the cost of kidney transplantation is very high, it costs 300,000-400,000 RMB, and we must wait for a suitable kidney source. These 300,000-400,000 yuan include the money for the kidney source, the cost of surgery, and the cost of immunosuppressive drugs after surgery. In addition to the disadvantages of costly kidney transplantation, there are also disadvantages such as low resistance of the patient, easy infection and tumor induced by the application of immunosuppressive drugs.
