急性肾功能衰竭(ARF)是指各种病因引起肾小球滤过功能急聚下降,导致水和代谢产物在体内潴留而表现的一组临床综合征。从病因上可分为肾前性,肾性和肾后性ARF。肾前性ARF指的是由于全身疾病如心血管疾病、失水、休克等导致有效血容量不足,肾血流量急骤下降导致肾小球滤过率(GRF)下降;肾后性ARF指的是输尿管、膀胱或尿道梗阻、尿液排出受阻,导致肾小管压力增加,GRF下降;肾性ARF是指肾脏本身疾病破坏,如急进性肾小球肾炎,急性肾间质性肾炎或者是肾小管缺血或中毒损害导致的急性肾小管坏死(ATN)。上述分类对指导临床诊
Acute renal failure (ARF) refers to a variety of causes caused by glomerular filtration dysfunction acute fall, leading to water and metabolites in the body retention and performance of a group of clinical syndromes. From the etiology can be divided into prerenal, renal and renal ARF. Prerenal ARF is due to systemic insufficiency due to systemic disease such as cardiovascular disease, dehydration, shock, etc., resulting in a sudden drop in renal blood flow resulting in decreased glomerular filtration rate (GRF); renal ARF refers to Ureter, bladder or urethral obstruction, urinary excretion obstruction, leading to increased pressure on the tubules, GRF decreased; renal ARF refers to the destruction of the kidney itself, such as acute glomerulonephritis, acute interstitial nephritis or renal tubular insufficiency Acute tubular necrosis (ATN) caused by blood or poisoning damage. The above categories guide the clinical diagnosis
