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.

Automated summary

This study compared the effects of two arterial anastomosis techniques on the outcome of kidney transplantation. The results showed no significant difference in creatinine levels and urine volume between the two surgical techniques. Only the urine volume on the 7th day after surgery had a significant effect on graft survival. There was no significant difference in graft survival between the two anastomosis techniques.
