Prerenal: Anything that causes decreased effective renal perfusion: Hypovolemia, CHF, Renal Artery Stenosis, Sepsis, etc. Remember, contrast-induced nephrology will often look pre-renal.
Intrinsic Renal: ATN, AIN, Glomerulonephritis, etc.
Postrenal: Obstruction (BPH, bladder stone, bilateral ureter obstruction)
