The renal capsule is a tough fibrous layer surrounding the
pararenal fat.[1]
The renal capsule resists stretching, limiting renal swelling, with important implications for renal circulation.[2] Stretching of the renal capsule due to swelling of the kidney causes flank pain.[3]
Structure
The renal capsule surrounds the functional tissue of the kidney, and is itself surrounded by a fatty adipose capsule, fascia, and fat. From the inner part of the kidney to outside the kidney, the positioning of the capsule is:
- renal medulla
- renal cortex
- renal capsule
- adipose capsule of kidney(or perirenal fat, or perinephric fat)
- renal fascia
- pararenal fat
- transverse fascia(posteriorly).
Sometimes the adipose capsule of the kidney also known as the perirenal fat, is regarded as a part of the renal capsule.[4]
