Key Features/Anatomical Relations

The renal sinus is located along the medial surface of the kidney.

Function

The renal sinus is the continuation into the kidney from the renal hilum and represents the entire collecting portion of the urinary system, which includes the minor calices, major calices, and the renal pelvis. The sinus also contains the renal vessels as they branch to enter the renal tissue as the renal arteries or converging to exit the kidneys as the renal veins.
