External Iliac Artery Anastomosis and Internal Iliac Artery Anastomosis for Artery anastomosis in Deceased-donor Kidney Transplantation and Multifactorial Analysis of Graft Survival.

OBJECTIVE: To determine the effects of surgical techniques applied to arterial anastomosis for kidney transplantation on the graft outcome. STUDY DESIGN: Observational study. PLACE AND DURATION OF STUDY: Organ Transplantation Center, Ataturk University Research Hospital and School of Medicine, Erzurum, Turkey, from January 2010 to January 2020. METHODOLOGY: In total, 143 consecutive patients who underwent deceased-donor-donor kidney transplantation during a 10-years period were retrospectively analysed. All patients were divided into two groups according to the vascular anastomosis techniques (end-to side external iliac and end-to-end internal iliac). The two groups were compared in terms of urine volume on postoperative days 1 and 7; blood creatinine levels on postoperative days 1, 2, and 7; complications; and graft survival. RESULTS: The mean patient age was 42.04 ± 11.1 years. No significant difference was observed between creatinine values ​​and urine amounts for both surgical techniques (p >0.05). Only the amount of urine on the postoperative 7th day had a significant effect on graft survival (p <0.05). There was no significant difference between the two anastomosis techniques in terms of graft survival (p >0.05). CONCLUSION: Both surgical techniques can be used safely in renal transplantation and arterial anastomosis. Also, decreased urine volume during follow-up can be considered as an early indicator of graft loss in the long-term.
