Introduction: Ureteral stenosis is one of the most commonly reported urological complications after kidney transplantation. Material and methods: This is a retrospective analysis of the risk factors for ureteral stenosis (type of donor, age of donor, presence of interior polar arteria, unilateral dual transplantation, diabetes mellitus of the recipient and the donor, BK positivity, child recipient, cold ischaemia time, and delayed graft function), as well as the causes and types of treating ureteral stenoses. Results: In the group of 278 patients, the occurrence was 7.2 %. The medial of occurrence of ureteral stenoses was 24.6 months. The independent risk factor for ureteral stenosis in our group was the age of the donor ≥ 70 years [HR 6.5833; 95 % CI 2.2448-19,3070 (P = 0.0006)], BK positivity [HR 13.6667; 95 % CI 6.9127-27.0196 (P 1080 min [HR 4.0368; 95 % CI 1.7250-9,4465 (P = 0.0013)], and diabetes mellitus in the donor’s history [HR 16.2667; 95 % CI 7.8629-33.6525 (P |
