临床上急、慢性肾功能衰竭盼鉴别,主要依据病史,包括起病急缓、病期长短、有无尿毒症及多系统损害等。自超声波技术普遍用于器官测量以来,肾脏体积亦是鉴别急、慢性肾衰的佐证,慢性肾衰者肾脏体积缩小,急性肾衰者肾脏体积增大。但在实际工作中,经常有许多患者既无明确的肾脏病史,又无肾脏体积的大小改变,此时,确给临床医师的诊治造成困难。人类指甲在其甲根形成过程中,可吸收血液中某 Clinical emergency, chronic renal failure hope identification, mainly based on medical history, including onset of acute and moderate disease, the duration of the disease, with or without uremia and multiple system damage.
