Urologic complications are the most frequent technical adverse events following kidney transplantation (KTX). We evaluated traditional and novel potential risk factors for urologic complications following kidney transplantation. Consecutive KTX recipients between December 1, 2006 and December 31, 2010 with at least 6 months follow-up (n=635) were evaluated for overall urologic complications accounting for donor, recipient, and transplant characteristics using univariate and multivariate logistic regression. Urologic complications occurred in 29 cases (4.6%) at a median of 40 days (range 1-999) post-transplantation, and included 17 ureteral strictures (2.6%), 5 (0.8%) ureteral obstructions due to donor-derived stones or intraluminal thrombus and 7 urine leaks (1.1%). All except two complications occurred within the first year of transplantation. Risk factors for urologic complications on univariate analysis were dual kidney transplantation (p =0.04) and renal artery multiplicity (p=0.02). On multivariate analysis, only renal artery multiplicity remained significant (aHR 2.4, 95% confidence interval 1.1, 5.1, p=0.02). Donation after cardiac death, non-mandatory national share kidneys, donor peak serum creatinine > 1.5 mg/dL or creatinine phosphokinase > 1000 IU/L, and donor down time were not associated with urologic complications. Our data suggest that donor artery multiplicity is an independent risk factor for urologic complications following KTX.
