[Acute renal failure in the elderly]

Abstract

Acute renal failure in elderly patients is common and likely to become more so as life expectancy in France continues to grow. The chances of acute renal failure occurring in the elderly are increased by changes in renal function and the effects of various chronic diseases such as diabetes, hypertension and obstructive urological disorders, all of which increase in incidence with age. The elderly may develop all types of the disease but are most prone to drug-related acute renal failure. The diagnostic and therapeutic strategies adopted are the same as those for adult patients but should take into account the potential risks and benefits in this specific age group. However, age should no longer be considered as the sole determining factor in diagnostic and therapeutic decisions. The elderly are among those who benefit most from preventive measures against acute renal failure.
