subject #253 1219

The renal hilum (Latin hilum renale) or renal pedicle of the kidney is the recessed central fissure. The medial border of the kidney is concave in the center and convex toward either extremity; it is directed forward and a little downward. Its central part presents a deep longitudinal fissure, bounded by prominent overhanging anterior and posterior lips. This fissure is named the hilum, and transmits the vessels, nerves, and ureter. From anterior to posterior, the renal vein exits, the renal artery enters, and the renal pelvis exits the kidney.

Hilum's Order

From anterior to posterior, the tubes entering the hilum of kidney are renal vein, renal artery and ureter. A useful mneumonic device for remembering this sequence is Virgins Are Unutilized.
