Either of the pair of major vessels which arise from the renal hilus and return blood from the kidneys, suprarenal gland and the ureter to the inferior vena cava.
The renal veins are veins that drain the kidney. They connect the kidney to the inferior vena cava. It is usually singular to each kidney, except in the condition 'multiple renal veins'. It also divides into 2 divisions upon entering the kidney: the anterior branch which receives blood from the anterior portion of the kidney and, the posterior branch which receives blood from the posterior portion. Often, each renal vein will have a branch that receives blood from the ureter. [WP,unvetted][Wikipedia:Renal_vein].
