Abstract

Background: In this retrospective study, we aimed to determine the variations of kidney arteries and veins in kidney donor patients who underwent preoperative, computed tomography angiography.

Materials and methods: We analyzed kidney computed tomography angiography findings of ninety-one donor nephrectomy patients operated from July 2016 through December 2017. Demographics, vascular diameters, abnormalities, numbers, branching variations, routing variations of arteries, and veins were assessed according to computed tomography angiography images. We also compared the radiological findings with perioperative findings.  Two radiologists evaluated computed tomography angiography images, and the same surgical team performed all donor nephrectomies by laparoscopic approach.

Results: Ninety-one of the 96 patients involved to study. Forty-six (50.5%) patients were female. Thirty-five (38.4%) of 91 cases had accessory arteries. Seven right (7.6%), one left (1.1%) and eight (8.7%) bilateral double hilar artery was observed on computed tomography angiography. No statistically significant difference was observed in the evaluation of the side of accessory/ polar arteries (p>0.05), and in the evaluation of the distribution of arterial/ venous variations according to perioperative findings (p>0.05). However, in the evaluation of computed tomography angiography images, we found that the diameter of the kidney artery and vein differed according to gender and side.

Conclusions: The knowledge of the vascular variations of the kidney is essential for surgeons performing kidney transplantation. It is also essential for urologist and vascular surgeons. Incompatible with the literature, the right kidney has more vascular variations and, one kidney artery is found in the majority of Turkish kidney donor patients.
