Abstract

Renal artery variations may relate to the origin, course, and end branches of renal artery divisions. To describe the morphology and topography of renal arteries in melanoderm living in Benin. This was a retrospective study from March 1, 2016 to April 31, 2017, i.e. 14 months. The study population consisted of all injected abdominal CT scans clearly highlighting the renal artery and its branches from the CT scan unit of CNHU-HKM. The data collected was entered into CSPro 6.2 software and then processed and analyzed using stata 13 software. The right renal arteries originated in an antero-lateral position on the aorta in 84.4% of cases, while those left in a mediolateral position in 45.9% of cases. They were projected mainly opposite L1 on the right and L2 on the left. Regarding their courses, all the arteries studied were concave posteriorly in the transverse plane and mostly concave above and upwards. Finally, the renal arteries mostly end by bifurcating into anterior and posterior branches in 88.5% of cases, by trifurcating in 1.5% of cases, rarely they divide into 4 branches. The renal arteries arise on the right in an antero-lateral position on the aorta and on the left in a medio-lateral position. They are lower located on the left with a concave path backwards and upwards then head upwards. Finally, they end by bifurcating. This knowledge is essential for patricians working on the kidneys.
