AbstractObjectivesUrinary tract infection (UTI) is the most common infectious complication after kidney transplantation. We aim to determine its impact on allograft function as indicated by several measures such as iothalamate glomerular filtration rate (iGFR), estimated glomerular filtration rate (eGFR), and creatinine value.MethodsWe performed a single‐center retrospective cohort study to determine the impact ofUTIon kidney allograft outcome.ResultsThe study population consisted of 301 kidney transplant recipients; 84% were living donor transplants. One hundred and one patients (34%) developed at least one episode ofUTIand the incidence ofUTIduring the first year after transplantation was 25%. At the end of the follow‐up, theiGFRwas lower among patients who had developed at least oneUTI(p = 0.044). However,eGFRand creatinine values were not significantly different betweenUTIand non‐UTIgroups.ConclusionWhen kidney function was measured byeGFRand creatinine, there was no significant difference in allograft function between kidney recipients with or withoutUTI. However, when kidney function was measured by nuclear studies, there was a tendency toward impairment in allograft function among patients who developed atleast oneUTIafter transplantation.
