    Background. In the present retrospective study, we analyzed the outcomes of patients transplanted with grafts with multiple renal arteries (MRAs). Patients and Methods. In total, 89 patients were transplanted with renal grafts with MRAs from 2003 to 2018. Demographic characteristics; type of donor; warm and cold ischemia times; arterial anastomosis technique; complications; graft function at first month, first year, and last outpatient clinic visit; and patient and graft survival were all retrospectively evaluated. Results. The mean age of the patients was 40.4 +/- 13.3 years. Fifty-six patients (62.9%) were male. In total, 42 patients (47.2%) received renal grafts from living related donors. In group A (n = 24; 27%), anastomosis was performed separately to the recipient external or internal iliac arteries; in group B (n = 38; 42.7%), the secondary artery was anastomosed to the main artery in a side-to-side fashion to form a single common orifice; in group C (n = 27; 30.3%), secondary arteries were anastomosed to the main renal artery in an end-to-side fashion. Creatinine clearance at the first month was significantly lower for deceased-donor grafts compared to living-donor renal grafts (P < .05). Creatinine clearance in the first postoperative month was significantly lower in group A and creatinine clearance in the first year was significantly lower in group C (P <.05). The best survival was found for anastomosis to the internal iliac artery (P < .05). Conclusion. MRAs can be safely used and the reconstruction technique does not matter if the graft kidney's arterial supply is preserved and the internal iliac artery is chosen for anastomosis.
