A case of successful renal allograft transplantation performed in a two-year-old female Dalmatian dog suffering from end-stage chronic renal failure is reported. A one-year-old male German shepherd with severely injured spinal cord was used as kidney donor. Simultaneous kidney allograft transplantation combined with hypothermic initial perfusion as graft conservation was done, placing the donor kidney into the right iliac fossa of the recipient. The immunosuppression protocol consisted of prednisolone and azathioprine. Regular physical, laboratory, ultrasonographic and scintigraphic examinations were used for assessing both the morphology and the function of the allograft. After a two-week period of hospitalisation the patient was discharged in a remarkably improving condition. The recipient died on postoperative day 45 of respiratory insufficiency resulting from secondary pneumonia and pulmonary oedema. Neither macroscopic nor microscopic abnormalities of the allograft were revealed by necropsy.
