ABSTRACT

Objective To elucidate the clinical characteristics and the outcome of acute renal failure (ARF) in the elderly. Methods Clinical data of 109 elderly patients(≥60 years) with ARF were analysed and compared with that of 175 younger adult ARF patients(18 40 years) in the same period. Results 109 out of 422 patients(25 8%) with ARF were more than 60 years. The mortality rate of ARF in these patients was 58 7%. ARF was induced mainly by prerenal factors (20 2%) and sepsis (15 6%). Complications such as infections (52 3% vs 29 7%), cardiovascular events (64 2% vs 38 3%), respiratory failure (43 1% vs 20 0%) and hyperkalemia (29 4% vs 15 4%) were more prevalent in elderly patient than that in the younger adult ARF patients ( P
