Detailed explanation-1: -Each kidney is held in place by connective tissue, called renal fascia, and is surrounded by a thick layer of adipose tissue, called perirenal fat, which helps to protect it. A tough, fibrous, connective tissue renal capsule closely envelopes each kidney and provides support for the soft tissue that is inside.

Detailed explanation-2: -Perirenal fat is a fat pad surrounding the kidneys, located between the renal fibrous membrane and the renal fascia in the retroperitoneal space [17].

Detailed explanation-3: -The renal fascia, commonly known as Gerota’s fascia, is a collagenous connective tissue sheath which separates the perirenal fat from the pararenal fat.

Detailed explanation-4: -Perirenal fat is a fat pad adjacent to the kidneys and is a type of visceral fat (14).

Detailed explanation-5: -Among visceral adipose tissue deposits, perirenal fat is located around and enclosed from the inner side of the abdominal musculature to the surface of the kidney, which can be easily measured by ultrasound, CT, and MRI scanning (8).
