Objectives Computerized tomography (CT) is the most accurate method for evaluating pelvic calcifications, which are of utmost importance for planning kidney transplantation (KT). The aim of our study was to eval-uate the incidence and distribution of iliac artery calcifi-cations and correlate the novel pelvic calcification score (PCS) with cardiovascular risk factors and graft and overall survival in KT patients.Methods We retrospectively included 118 KT patients operated at our institution with pretransplant pelvic CT. Calcification morphology, circumference and length of both common and external iliac arteries were inde-pendently scored by two uroradiologists. PCS was calculated as the total score sum of all three calcifica-tion features in all vessels. PCS correlation with graft and patient survival was performed.Results Calcification in at least one vascular segment was found in 79% of patients. PCS was significantly higher in male patients (p = 0.006), patients over 55 years (p < 0.001), and patients on haemodialysis (p = 0.016). Patients with a PCS >3 had significantly shorter graft and overall survival rates (p = 0.041 and p = 0.039, respectively).Conclusions The extent of iliac artery calcification in KT recipients quantified by PCS on pretransplant CT corre-lates with graft and overall patient survival. A PCS over three was associated with worse clinical outcomes and could become a possible prognostic factor.Advances in knowledge Our novel PCS is a robust method for quantifying iliac artery calcification burden. Since higher a PCS correlates with worse patient and graft survival, PCS has the potential to become a prog-nostic factor in kidney transplant patients.
