Acute renal failure in the elderly

Acute renal failure in the elderly (ARF) refers to the sudden loss of renal function caused by various reasons, which may be reversed if properly treated. In recent years, with the continuous advancement of medical technologies such as dialysis, intravenous high nutrition, and antibiotics, the treatment of ARF has significantly improved. However, its fatality rate continues to be as high as 50% to 70%, and one of the main reasons may be elderly patients in ARF. The proportion of patients is increasing and elderly patients undergo more complicated surgical procedures. Studies have shown that among the elderly with multiple organ failure, the mortality rate of those with renal failure is significantly higher. Therefore, in recent years, the ARF of the elderly has attracted more and more attention.
