Appraisal of the porcine kidney autotransplantation model

Animal models are extensively used for transplantation related research, especially kidney transplantation. Porcine autotransplantation models are considered to be favorable regarding translatability to the human setting. The key determinants for translatability of the model are discussed, comprising animal age, development, anatomy, anesthesia and surgical protocols, and perioperative care. With the detailed discussion of these determinants and the pitfalls in diagnosing animal discomfort, an attempt is made to provide a uniform porcine kidney autotransplantation model with tools to improve currently used models.
