Organ transplantation remains the definitive treatment for many patients with end-stage organ failure, significantly improving survival and quality of life. Nevertheless, the persistent shortage of donor organs continues to limit access to transplantation worldwide, creating an urgent need for alternative strategies capable of expanding the donor pool. This review aimed to analyze current advances in organ transplantation and xenotransplantation, with emphasis on surgical innovations, immunological developments, clinical outcomes, and bioethical implications. A narrative review was conducted using the Scientific Method as a methodological framework. Scientific evidence was obtained from major biomedical databases, including PubMed, Scopus, Web of Science, ScienceDirect, Google Scholar, and the Cochrane Library. The selected literature was analyzed according to four major domains: surgical innovation, immunological and genetic advances, clinical outcomes, and bioethical considerations. The findings demonstrated that conventional transplantation continues to achieve favorable graft survival and patient outcomes due to improvements in surgical techniques, organ preservation, and immunosuppressive therapy. Furthermore, recent clinical experiences involving genetically modified porcine organs have demonstrated the growing feasibility of xenotransplantation as a potential solution to organ scarcity. However, important challenges remain regarding long-term graft survival, immunological compatibility, infectious disease transmission, animal welfare, informed consent, and equitable access to transplantation services. The review concludes that xenotransplantation represents one of the most promising emerging strategies for addressing the global organ shortage, although its successful integration into clinical practice will require continued scientific advancement, ethical oversight, regulatory preparedness, and international collaboration.
