慢性肾功能衰竭(CRF)是指原发性或继发性慢性肾脏疾病造成肾脏结构、功能严重损害并引起的系列临床症状所组成的综合征。个别情况下,CRF也可由急性肾衰转变而来。CRF的发展过程是缓慢的,但从总体上来说,这一过程是不可逆的。临床上一般根据病情轻重和肾小球滤过率(CRF)下降的程度或血清肌酐水平,将CRF分为若干阶段。1992全国肾小球疾病座谈会建议将CRF分为以下几个阶段:(1)代偿期血清肌酐(Scr)133～177μmol/L);(2)早中期失代偿
Chronic renal failure (CRF) is a syndrome that consists of a series of clinical symptoms caused by primary kidney damage or kidney damage caused by chronic kidney disease. In some cases, CRF can also be caused by acute renal failure. The development of CRF is slow, but generally speaking, this process is irreversible. CRF is generally divided into several stages based on the severity of the disease and the extent of glomerular filtration rate (CRF) decline or serum creatinine levels. The National Symposium on Glomerular Diseases in 1992 recommended that CRF be divided into the following stages: (1) compensatory serum creatinine (Scr) 133 ~ 177μmol / L); (2)
