OBJECTIVE: To investigate the prevalence and distribution of renal arteries and their branches in vivo, correlating the particularities found in them with sex and laterality. METHODS: Two hundred renal pedicles were studied by CT angiography and its arteries analyzed according to number, position of origin, size, length and trajectory in relation to renal segments. Its frequency and laterality were surveyed regarding gender and age. RESULTS: There were multiple arteries in 61.5% of the pedicles (56% in the right and 67% in the left), occurring in 65% of men and 58% of women. The aortic origin to the multiple arteries was more frequent on the right and, more often, the renal arteries originated between vertebrae L1 and L2 as pre-hilar division of the main artery. The average length of the main artery was higher in right kidneys with a single artery. There was no difference between the diameters of the main renal arteries. CONCLUSION: There is a higher prevalence of multiple renal arteries than the one described in the literature, with no difference for gender or laterality. The renal arteries originated more frequently between vertebrae L1 and L2, with divisions of the pre-hilar route and main artery to the hilum of the kidney. The average length of the main artery is greater on the right and in kidneys with single artery. There was no difference in diameter between the main renal artery between kidneys with single and multiple arteries.
