Abstract

Background
In renal transplantation, the most common way to anastomose single donor renal artery to recipient is using inter-nal iliac artery or external iliac artery. We compared the outcomes between the two groups.
Methods
From 2005 to 2021, the medical records of 381 patients who underwent renal transplantation at Seoul National Uni-versity Bundang Hospital were retrospectively examined. Hospital stay, serum creatinine level, GFR (MDRD), graft survival (death censored), patient survival were compared.
Results
The hospital stay after surgery was longer in external group than in internal group (P=0.08). Short-term GFR up to 40 days after surgery was significantly higher in the internal group than external group (P<0.01). There was no difference between the two groups in 5-year graft survival (P=0.755). There was also no difference between the two groups in the case of 5-year patient survival (P=0.218). We divided the patient into four groups, living donor renal transplantation with internal anastomosis, liv-ing donor renal transplantation with external anastomosis, deceased donor renal transplantation with internal anastomosis, and deceased donor renal transplantation with external anastomosis. There was no difference among the subgroups (P=0.652).
Conclusions
Although the internal group showed better results in postoperative hospital stay and short-term GFR, there was no significant difference in 5-year long-term graft survival and patient survival between two groups. Therefore, it is desirable to select appropriate anastomosis among the two methods according to the condition of donor kidney and the anatomy of recipient.
