The renal capsule and Gerota's fascia delimit the kidney. A rapid expansion within these structures could cause a compartment syndrome with compression of blood vessels.


Possible causes for expansion within the delimited areas:

(1) marked renal edema associated with acute renal failure

(2) hemorrhage secondary to blunt trauma or vascular rupture


Clinical features:

(1) worsening of renal function

(2) rapid and marked expansion within the capsule or fascial space

(3) improvement in renal function on decompressing the kidney

(4) exclusion of alternative explanations
