The renal arteries usually arise from the aorta at the level of L2 below the origin of the superior mesenteric artery (Fig. B). The renal arteries enter the renal hilus anterior to the renal pelvis. The main renal arteries divide into segmental arteries next to the renal hilum. The first branch usually is the posterior branch; following this branch, anterior segmental (ie, apical, upper, middle, and lower) arteries are visible. The segmental arteries divide into the lobar arteries. Further divisions are the interlobar, arcuate, and interlobular arteries. MDCT (16 slice) clearly demonstrates the interlobar artery level of the renal arterial anatomy.
Coronal CT angiogram in a renal donor demonstrates renal arterial anatomy; arrows point to renal arteries.
