Renal surface of suprarenal gland

The renal surface of the suprarenal (adrenal) gland is the inferior (basal) surface of the gland that rests directly upon the upper pole of the kidney. It is the broad, concave, inferiorly directed surface through which the suprarenal gland maintains its intimate anatomical relationship with the ipsilateral kidney, separated only by a thin layer of connective tissue (perirenal fat and Gerota's fascia).

Anatomical details by side:

• Right suprarenal gland: The renal surface is a broad, flat base that sits on the anteromedial aspect of the upper pole of the right kidney. The right gland has a pyramidal or triangular shape, and its renal surface is its largest surface.

• Left suprarenal gland: The renal surface is the inferior aspect that rests on the medial border and upper pole of the left kidney. The left gland is more semilunar (crescent-shaped), and its renal surface extends along the medial margin of the kidney.
