Renal vein
The renal veins in the renal circulation, are large-calibre[1] veins that drain blood filtered by the kidneys into the inferior vena cava. There is one renal vein draining each kidney. Each renal vein is formed by the convergence of the interlobar veins of one kidney.[2]

Because the inferior vena cava is on the right half of the body, the left renal vein is longer than the right one.
Clinical significance[edit]
Diseases associated with the renal vein include renal vein thrombosis (RVT) and nutcracker syndrome (renal vein entrapment syndrome).
