Abstract: As the only effective treatment for end-stage diseases, organ transplantation has been facing core challenges such as shortage of donor organs, technical bottlenecks, and inadequate system construction. Based on the practical experience of the organ donation and transplantation team of the First Affiliated Hospital of Xi’an Jiaotong University, this article systematically reviews the pathways for the specialization of organ donation and the disciplinary development of Organ Procurement Organization (OPO). It thoroughly analyzes the innovative achievements in kidney transplantation, including key breakthroughs in the establishment of technical standards for donor and organ evaluation, preservation and repair, the research and development of mechanical perfusion repair systems, the creation of an independent human leukocyte antigen (HLA) detection platform, and the improvement of the rejection prevention and control system. Meanwhile, combined with the latest research progress at home and abroad, this paper discusses current issues in the field of organ donation and transplantation such as the utilization of marginal donors, multidisciplinary collaboration, and ethical norms. It proposes a future direction to promote the systematic disciplinary development with "Chinese Technology, Chinese Standards, and Chinese Solutions", providing a reference for the high-quality development of organ transplantation in China.
