    Abstract:
    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.
