Key Features/Anatomical Relations

The renal pyramids make up a majority of the renal medulla. A renal column separates adjacent pyramids.


The collecting ducts within the renal pyramids direct urine towards the renal papilla where each pyramid is surrounded by single minor calix. Urine is then transported to a major calix, the renal pelvis and out of the kidney.
