Among the transplants of various types of organs in the clinic, renal transplantation technology is more mature, and its short- and long-term prognosis is also better. With the advancement of surgical techniques and the introduction of a variety of potent immunosuppressive agents, the incidence of acute rejection in renal transplantation has been significantly reduced, and chronic rejection has gradually become the most difficult immune problem. Even so, kidney transplantation is more mature than other types of organ transplantation, and its prognosis is better than other types of transplantation. The indication for kidney transplantation is the progression of various renal diseases to the stage of chronic renal failure, and studies have shown that kidney transplantation is significantly better than dialysis treatment for uremia in terms of long-term life expectancy, quality of life, and medical costs. Therefore, in the absence of contraindications, receiving a kidney transplant as early as possible can bring better treatment results.
