尿变形红细胞的临床意义及终末尿渗透压对尿红细胞形态的影响

本文应用涂片染色法对42例血尿患者尿红细胞形态及终末尿渗透压对红细胞形态的影响进行了观察。发现终末尿渗透压对红细胞形态有一定影响,但不会造成红细胞严重变形。提示尿严重变形红细胞是诊断肾小球性血尿的指示性细胞。本组以严重变形红细胞>30％作为肾小球性血尿诊断标准时尚未出现漏诊或误诊情况。认为涂片染色法观察尿中红细胞形态可区别肾小球性血尿和非肾小球血尿。

SIGNIFICANCE OF URINARY DISFIGURATED ERYTHROCYTES AND THE INFLUENCE OF END URINE OSMOTIC PRESSURE ON URINARY ERYTHROCYTE MORPHOLOGY

By means of smear staining method we observed the morphologic features of urinary erythrocytes and the influence of osmotic pressure of the end urine on ery- throcyte form in 42 patients with hematuria.Though having an influence on the form of erythrocytes,the osmotic pressure of end urine can't cause serious disfiguration of erythrocytes.Our observation shows that the serious disfigurated erythrocytes are indicating cells to define glomerular hematuria,with the serious disfigurated ery- throcytes>30% taken for diagnosis standard of glomerular hematuria we haven't had failing to diagnose or misdiagnosis.The result suggests examining the morpho- logic features of erythrocytes in the urine with smear staining method can distinguish between glomerular and nonglomerular hematuria.
