    Abstract

    Approximately 250 bladder-washing and voided urine specimens from normal, and inflammatory and malignant lesions were examined using light microscopy (LM), scanning electron microscopy (SEM) and a newly-designed mesh. This specific mesh, containing 42 compartments in 25 mm2 on gelatine- coated glass-slip, permitted us the direct correlation of LM and SEM images. With SEM, malignancy of exfoliated urothelial cells mainly depended on the presence or absence of pleomorphic microvilli. Subsequently, a new “SEM grading” regarding human urinary cytology was proposed.
