[Morphologic study of microscopic hematuria using phase contrast microscopy].
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.
