Purpose of the study: Reducing the risk of early postoperative complications associated with the disorder of the blood supply to the donor’s ureter while carrying out the transplantation of a cadaveric kidney. Material and methods: The analysis of a complicated course of the postoperative period, associated with the peculiarities of the blood supply to the donor’s ureter, was carried out for 20 out of 410 (4.9%) patients with chronic renal failure, who had the cadaveric kidney transplanted in Brest regional clinical hospital from 2011 to 2020. Results: A technique of determining the anatomical benchmarks indicating the location of the vessels that feed the donor’s ureter has been developed. Mastering specific technical methods used during the preparation of the renal allograph and its implantation, made it possible to reduce the number of urological complications after kidney transplantation by more than 2 times, and the number of cases of postoperative necrosis of the ureter by 4 times. Conclusions: The proposed surgical techniques make it possible to reduce the risk of postoperative complications associated with the violation of the blood supply of the donor’s ureter while transplanting the cadaveric kidney.
