462 Is Donor Renal Arterial Anastomosis to the External Iliac Artery Comparable to the Internal Iliac Artery in Living Donor Renal Transplantation?

Abstract

Abstract Background In renal transplantation, the donor artery may be anastomosed to the external iliac artery (EIA) or the internal iliac artery (IIA). Few retrospective studies have not observed any difference in outcomes between these techniques. We aimed to compare these two techniques in a series of living donor renal transplants from a single institution. Method We retrospectively included 345 patients undergoing living donor renal transplantation who were divided into two groups: Group A (153 patients): anastomosis to IIA; and Group B (192 patients): anastomosis to EIA. The recipient characteristics, post-operative complications, Resistivity Index (RI) measured by colour Doppler on day 5 and at last follow-up and renal function were compared between the two groups. Results The demographic characteristics were similar. Mean operative time was longer in Group B compared to Group A (284 versus 244 minutes; p<0.001). Post-operative complication rates were similar. Mean follow-up was 27 months. Renal artery peak systolic velocities were higher in Group B compared to Group A (192 versus 135 cm/sec, p<0.01) while mean RI values were similar (0.73 and 0.61, p = 0.28) at last follow-up. There was no difference in mean creatinine (A: 1.23 mg% vs B: 1.36 mg/dL) at last follow-up. Conclusions The operative time was longer in EIA compared to IIA anastomosis. However, there was no difference in complications, vascular and renal function between the two groups. Therefore, the two techniques are comparable.
