ABSTRACT
In this review the more commonly observed causes of acute renal failure in the elderly will be discussed. The great spectrum of causes of acute renal failure that can occur in both young and in older patients will not be elaborated on. The physiological alterations in the kidney that occur with aging will be highlighted to explain the potential susceptibility of the older kidney to insults resulting in acute renal failure. A practical diagnostic approach based on the history, physical examination, and simple biochemical tests will be outlined, followed by discussions regarding specific, common causes of acute renal failure in the elderly (Table 1) and a brief description of therapeutic options.
