Renal vein

Dr Henry Knipe et al.

The renal veins are asymmetric paired veins that drain the kidneys

Course

The renal vein is formed by the union of two-to-three renal parenchymal veins in the renal sinus. It emerges from the renal hilum anterior to the renal artery and drains into the inferior vena cava at the level of L2. 

The left renal vein is much longer, at 6-7cm, than the right renal vein, at 3-4cm, but they have a similar calibre (~1.2cm). The left renal vein courses anteriorly to the abdominal aorta
