Secondary to Prerenal or Renal Cause (Intrinsic). Intrinsic Cause of A.R.F. M.C is Acute Tubular Necrosis
A.R.F. = Acute Tubular Necrosis = Renal Ischemia (shock), Crush Injury (myoglobulinuria, rhabdomyolysis), Toxins.
PRERENAL A.R.F. is the M.C. form of KIDNEY FAILURE in USA. Four general processes lead to prerenal A.R.F, as follow:
HYPOVOLEMIA, LOW CARDIAC OUTPUT, SYTEMIC VASODILATION and SELECTIVE RENAL VASOCONSTRICTION.
URETERIC OBSTRUCTION produces POSTRENAL A.R.F. In the USMLE it is use as a distractor.
