The veins of the right half of the male pelvis. (Third lumbar labeled at center top.)
|Drains to||Inferior vena cava|
They are four in number and accompany the four lumbar arteries, with the vein lying superior to the artery (the same arrangement as in the intercostal neurovascular bundles). The first and second lumbar veins usually join the ascending lumbar vein rather than the inferior vena cava, which then joins the subcostal vein of the same side to form the azygous vein on the right or hemiazygous vein on the left. The third and fourth lumbar veins on the left pass behind the abdominal aorta to reach the inferior vena cava and all lie behind the sympathetic trunks.
The iliolumbar veins join the common iliac veins.
