Late at night on April 30, 2014, the operating room of Qilu Hospital was brightly lit on the upcoming May Day. Professor Tian Jun of the Organ Transplantation Department, on the basis of successfully completing 16 cases of kidney transplantation in April, successfully carried out another kidney transplantation with a difficult infant donor kidney, which marked that the kidney transplantation technology of our hospital had reached the international advanced level. The 30-year-old uremia patient Wang received this gift of life from a 9-month-old baby. The parents of the baby, who were in great pain after learning that their child had died due to severe trauma, decided that they would donate their child’s organs to the uremia patient in the hope that a part of their child’s organs would survive in the world, and also as an appeal to the society to support organ transplants. The volume of the donor kidney is only the size of a mountain egg, the tubular diameter of the donor kidney artery is 2mm and the tubular diameter of the donor kidney vein is about 3mm, and the tubular wall is very thin and prone to spasms, which makes the cutting, trimming, and transplantation of the donor kidney a huge technical challenge. Can such a small kidney be transplanted? Even if the transplantation is successful, can such a small kidney take on the functions of an adult? If the kidney transplant is unsuccessful, can the patient and his family accept it? Is it worthwhile to take such a big risk against the background of the tense relationship between doctors and patients nowadays? The team led by Prof. Tian Jun made full preparations for the high incidence of vascular and ureteral complications in infants and young children. As early as one year ago, the team collected similar surgical cases from countries all over the world, categorized and sorted them, and studied them in depth for kidney transplantation for infants and young children. We have had many academic exchanges with American experts, and at the same time, we have learned from the experience of our domestic counterparts in pediatric donor kidney transplantation. Before this case of kidney transplantation for a younger pediatric patient, a one-and-a-half year old pediatric donor kidney transplantation was successfully performed in January this year. Facing the more complicated and difficult kidney transplant, Prof. Tian Jun planned carefully and thoughtfully, made sufficient plans for all the problems encountered, and cooperated with the anesthesiologist during the operation to give full play to the overall advantages of our hospital. After 4 hours of intense surgery, the donor kidney “settled” successfully and began to work immediately, and urine gushed out. During the perioperative period, which was during the May Day vacation, the transplantation team led by Prof. Tian Jun did not relax at all, and carried out perfect anticoagulation treatment and close clinical monitoring, successfully avoiding vascular and ureteral complications, and the recipient’s blood creatinine steadily declined, and fell to normal 4 days after the operation. Shortage of kidney source has always been a bottleneck problem plaguing the development of transplantation, and the rational and effective utilization of infant donor kidneys is undoubtedly a positive attempt to solve the problem. Prof. Tian Jun said that the significance of this highly advanced surgery not only saved the life of Wang’s family, but more importantly, the surgery proved that the use of cardiac and cerebral dead infants and young children’s donor kidneys can be used as a way of expanding the source of donor kidneys, which is perhaps more significant to the cause of organ transplantation than the technological advancement itself.
