每一显微和肉眼血尿,亦即红细胞随尿液排出,是一个临床发现,必须予以查清。显微血尿有时难以同生理性血尿区别,后者红细胞计数可至15万个/1小时,需进而作定量检查,如爱迪氏计数等。肉眼血尿必须与溶血时出现的血红蛋白尿鉴别,此时尿内找不到红细胞。尿色变红也发生于摄入某些药物后,如匹拉米洞、酚类缓泻剂。0.5～1.0毫升血溶于1公升尿内即出现肉眼血尿。一般肉眼血尿多来自泌尿道,显微血尿则往往是肾源性的。无症状的血尿要作出诊断必须进行细致的临床检查,包括一系列检验。血尿可来源于许多疾
Each microscopic and gross hematuria, ie, red blood cells excreted with the urine, is a clinical finding that must be identified. Microhematous hematuria sometimes difficult to distinguish with the physiological hematuria, the latter red blood cell count up to 150,000 / 1 hour, to be followed by quantitative examination, such as Aidi’s count. Gross hematuria and hemolytic hemoglobinuria must be identified when the urine can not find red blood cells. Urine turn red also occurs after ingestion of certain drugs, such as Pmi hole, phenols laxatives. 0.5 ~ 1.0 ml blood dissolved in 1 liter of urine that appears gross hematuria. Most gross hematuria from the urinary tract, micro-hematuria is often nephrogenic. Asymptomatic hematuria to make a diagnosis must be meticulous clinical examination, including a series of tests. Hematuria can come from many diseases
