Recently, a mother in Dalian resolutely decided to donate one of her healthy kidneys to her son suffering from uremia. On December 8th, the mother and son successfully underwent an all-robot parent kidney transplantation in the Second Affiliated Hospital of Dalian Medical University (referred to as the Second Hospital of Dalian Medical University for short). On December 20th, mother and son were discharged from the hospital smoothly with full blessings and longing for the future.

Four years ago, 28-year-old Xiao Zhang suffered from uremia and needed regular hemodialysis treatment. This news was like a bolt from the blue, which dealt a heavy blow to Xiaozhang's family. Xiaozhang's dialysis life is not smooth. During the dialysis process, Xiaozhang often suffers from dizziness, nausea and unstable blood pressure. After communicating with patients, he learned that "kidney transplantation" is the only way to cure the disease. With the mentality of giving it a try, Xiaozhang came to the organ transplantation center of the Second Hospital of the University of Medical University. When she learned that kidney transplantation could be performed among immediate family members, Xiaozhang's mother said she could donate a healthy kidney to her son.

After careful examination, the doctor found that the mother's blood type was type A and the child was type B. Can the parent kidney transplant be performed? Wang Liming, director of the center, said: Parent kidney transplantation with ABO blood group incompatibility is possible. Previously, the Second Hospital of University of China took the lead in carrying out ABO blood group incompatible kidney transplantation in Liaoning Province and accumulated rich experience. Combined with Xiaozhang's actual condition, the organ transplantation center decided to adopt the latest blood group-free antibody clearance scheme. Through drug treatment, Xiaozhang's blood group antibody quickly reached the standard of cross-blood group transplantation. At the same time, after full evaluation and discussion, the medical team decided to adopt a brand-new minimally invasive surgical scheme-total robot kidney transplantation, that is, the donor uses a robot to take the kidney and the recipient uses a robot to implant the kidney.

After full preparation, on the morning of December 8th, the operation was carried out as scheduled. The incision of robotic minimally invasive kidney removal is only 1/3 of that of traditional surgery, and the amount of bleeding is less, which can greatly reduce the trauma to the donor. During the operation, Liu Zhiyu, the academic leader and dean of urology, used the robot to carefully free the kidney. With the assistance of the robot's clear stereoscopic image and the flexible manipulator arm, the blood vessels of the kidney were fully revealed, and the difficulty of donor blood vessel variation was overcome. The kidney was successfully obtained. Subsequently, in order to protect the donor kidney to the maximum extent, Wang Liming, a professor at the Organ Transplantation Center of the Second Hospital of the University of Medical University, and Song Turun, a professor at the Kidney Transplantation Center of West China Hospital, immediately performed kidney perfusion, trimmed the kidney with the finest finish and adopted low temperature perfusion. Under the guidance of Lin Tao, a professor at the Kidney Transplantation Center of West China Hospital, the doctor established an operating channel through a small incision of 1cm on the body surface to complete the full free of the patient's right iliac blood vessel, and then put the donor kidney into the donor kidney through a surgical incision of only 5cm in the abdomen. Under the delicate manipulation of the robotic arm, the operation was successfully completed.

Wang Liming said that robotic surgery can present a clear three-dimensional intuitive image almost to the naked eye under an enlarged field of vision, and can accurately complete difficult dissection and suture at any angle in a narrow space. In terms of donor surgery, the robot operation and separation are more accurate and stable, and can better cope with various situations of narrow space and vascular variation; In terms of recipient surgery, robot-operated sutures are more delicate and reliable, which not only reduces the pain of patients, reduces complications, but also greatly shortens the recovery time.
