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:

  1. renal medulla
  2. renal cortex
  3. renal capsule
  4. adipose capsule of kidney
    (or perirenal fat, or perinephric fat)
  5. renal fascia
  6. pararenal fat
  7. 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]
