顕微鏡的血尿の位相差顕微鏡における形態的検討

Abstract

外来患者で顕微鏡的血尿のみられた217症例について, 尿沈渣の赤血球の形態を位相差顕微鏡で調べ, 臨床診断との関係を比較検討した.膀胱白板症の症例で90%に腎炎型を示す結果を得た.位相差顕微鏡によって, 赤血球の変形を調べることは, 腎炎と非腎炎との鑑別に有用であるとされているが, 膀胱白板症においても腎炎型を示すものが多い

Phase contrast microscopic examination of the urine has been recently reported to be valuable in predicting whether hematuria is due to glomerulonephritis or not. Phase contrast microscopy can differentiate glomerular red cells from nonglomerular ones since the former varies in size and shape with distortion, whereas the latter is uniform in size and shape. Urinalysis of 217 cases of microscopic hematuria was performed at our Hospital. Red blood cells were classified into two types, glomerular and nonglomerular type. Ninety percent of the cases of bladder leukoplakia as well as all cases of glomerulonephritis had glomerular type red blood cells.
