急性肾衰竭 Acute renal failure CARF)
急性肾衰竭 Acute Renal Failure （ARF）
DEFINITIONS AND INCIDENCE UAcute renal failure(ArF)is a syndrome characterized by rapid decline in glomerular filtration rate(GFR) and retention of nitrogenous waste products such as blood urea nitrogen(BUN)and creatinine U aRF complicates approximately 5% of hospital admissions and up to 30% of admissions to Intensive care units
