Data on the impact of donor-to-recipient laterality on kidney transplantation are lacking. This study evaluated the impact of donor-to-iliac fossa laterality and the site of venous anastomosis on operating time and surgical outcome. This retrospective single-center study analyzed 1262 deceased donor adult kidney transplants into pristine iliac fossa. Multivariable linear and logistic regression analyses were used to identify variables with an impact on operating time and surgical complications. Operating time was shorter by 11 min in median for transplantations into the right iliac fossa compared to the left iliac fossa (p < 0.001). Operating time in left-to-right donor-to-recipient combination was shorter by 17 min in median if venous anastomoses were performed on the caval vein or common iliac vein as compared to anastomoses to the external iliac vein (p < 0.001). Overall, the shortest operating times (median 112.5 min) were achieved in left-to-right donor-to-recipient combinations with venous anastomosis to the caval or common iliac vein, without an increase in surgical complications. Kidney transplantation into the right iliac fossa with anastomosis to the caval vein or the common iliac vein saves operating time and reduces thrombotic complications. Acceptance of a left donor kidney is likely to further reduce operating time.
