Origin
The renal arcuate veins converge along the corticomedullary junction at the superficial end of each renal column to form the interlobar veins.
Course
From the corticomedullary junction at the superficial end of the renal columns, the interlobar veins travel parallel to the axis of the column from superficial to deep. There is one interlobar vein per column (lobe). Each vein accompanies an interlobar renal artery.
Tributaries
The interlobar veins receive the arcuate veins.
Structures Drained
The interlobar veins drain the renal cortex and medulla.
