title: Acute renal failure.
abstract: ARF is a common clinical problem associated with significant morbidity and mortality. Therefore, rapid and accurate diagnosis is imperative. Initial diagnostic strategies should be directed toward distinguishing among prerenal, renal, and postrenal causes of ARF. This can be done by the use of urinary diagnostic indices in concert with radiologic investigation, renal biopsy, and hemodynamic monitoring when appropriate. Treatment of established ARF should be directed toward maintaining fluid and electrolyte homeostasis and controlling complications resulting from retained nitrogenous waste products. This may necessitate the aggressive use of dialysis. As yet, there is no proven means to prevent ARF or alter the course of ARF once it is established.
