Structure/Morphology
The posterior layer of renal fascia is the layer of fascia that forms the posterior margin of the perirenal space. It extends superiorly to bound the posterior of the adrenal gland as well as inferiorly along with the ureter.

Anatomical Relations
The posterior layer of renal fascia separates the perirenal space anteriorly from the fascial layer that forms the posterior wall of the retroperitoneum. Inferiorly, the posterior perirenal fascia follows the ureters down into the pelvic cavity. Superiorly, it blends together with the anterior perirenal fascia briefly before splitting to run up the posterior side of the adrenal glands. Laterally, the anterior and posterior perirenal fascia are continuous with each other merging with the lateroconal fascia in the colonic gutter. Medially, the posterior perirenal fascia can run across the midline anterior to the aorta and inferior vena cava and merge with the posterior perirenal fascia of the opposite side (Mirilas and Skandalakis, 2009; Standring, 2016).
Function
The posterior layer of renal fascia forms the posterior wall of the perirenal space. It, together with the anterior layer of renal fascia, encompasses the kidneys, adrenal glands, and ureters.

Fascia
The fascia is also defined as a “the fascial system consists of the three-dimensional continuum of soft, collagen containing, loose and dense fibrous connective tissues that permeate the body” by Fascia Nomenclature Committee (Bordoni and Whitte, 2018), an as “masses of connective tissue large enough to be visible to the unaided eye” by Gray’s Anatomy (Standring, 2016).
