The '''renal columns''', '''Bertin columns''', or '''columns of Bertin''', a.k.a. '''columns of Bertini''' are extensions of the [[renal cortex]] in between the [[renal pyramid]]s. They allow the cortex to be better anchored. (Cortical extensions into the medullary space.)

Each column consists of lines of blood vessels and urinary tubes and a fibrous material.

A hypertrophied renal column (or ''renal pseudotumor'') may be differentiated from an actual [[renal tumor]] with the help of a [[DMSA scan]]. The scan will show the area as one with normal activity if it is a pseudotumor or will show decreased uptake if it is a cystic or solid renal mass.
