血尿一般又分为肉眼血尿及显微镜下血尿两种,前者系指肉眼能见到尿液呈血样或洗肉水样或凝血块者;后者则仅在显微镜下见到红细胞,但尿内红细胞正常值是多少?采用何种检查方法,国内外至今仍有很大争论,尚无统一的血尿诊断指标.目前国内镜下常规检查正常人尿红细胞0—1/HP或0—2/HP;北京医学院附属第一医院1979年对219例正常儿童尿常规进行观察研究;用直接涂片法检查镜下红细胞为0或偶见,用离心沉淀法则红细胞为0—1/HP;有些单位采用平板计数法:正常尿中红细胞<5/ml,5～25/ml 为可疑血尿,>25/ml 则肯定为血尿。
Hematuria is generally divided into gross hematuria and microscopic hematuria two, the former refers to the naked eye can see the urine was washed or water samples or clots; the latter only to see the red blood cells under the microscope, but the urinary red blood cells What is the normal value? What kind of inspection methods, there is still a lot of controversy at home and abroad, there is no uniform diagnostic indicators of hematuria.At present, the routine examination of normal urine urinary red blood cells 0-1 / HP or 0-2 / HP; The First Affiliated Hospital of Beijing Medical College in 1979 to 219 cases of normal urinary routine observation; direct smear microscopy of erythrocytes 0 or occasionally, using centrifugation precipitation of red blood cells 0-1 / HP; some units using Plate count method: normal urine red blood cells <5 / ml, 5 ~ 25 / ml for suspected hematuria,> 25 / ml is certainly hematuria.
