Objective:
This study aims to compare the outcomes of two arterial anastomosis techniques in kidney transplants with multiple renal arteries: the "pants" technique, which consolidates arteries into a single anastomosis, and the separate anastomosis technique, which connects each artery individually. We evaluated resistive index (RI) and flow rates of renal and interlobar arteries in recipients of both techniques.
Methods:
At Gaziantep University Organ Transplant Center, we compared outcomes in kidney transplant recipients with multiple arteries who underwent either the pants (26 patients) or separate anastomosis (29 patients) techniques from 2010 to 2021. Data on resistive index and flow rates were obtained from postoperative Doppler examinations and medical records.
Results:
Among 55 grafts (52 with 2 arteries and 3 with 3 arteries), postoperative Doppler exams showed no significant differences in resistive index between the two techniques. For the pants technique group, the renal artery RI averaged 0.71 on the first and third days and 0.70 on the second day, while the interlobar artery RI was 0.70, 0.68, and 0.72 on days 1, 2, and 3, respectively. In the separate anastomosis group, renal artery RI averaged 0.70 across all days, and interlobar artery RIs were 0.66, 0.65, and 0.68, respectively. No significant differences were found between the groups (P > .05).
Conclusion:
Both anastomosis techniques yielded comparable outcomes in terms of RI and flow rates. However, the separate anastomosis technique had shorter anastomosis and cold ischemia times, suggesting it may offer logistical advantages without compromising graft function.
