title: Acute renal failure: a diagnostic dilemma.
abstract: This patient had severe dehydration and renal failure presumed to be extrarenal. After volume replacement, the course was not typical for simple extrarenal azotemia or acute tubular necrosis. Tubular handling of salt and water may not provide adequate criteria to evaluate the cause of reduced glomerular filtration rate.
