The scanning electron microscopy has recently been proved by Jaques et al. to be an excellent method for examining the surface structure of soft issues. This method, by its advantages of visualization of depth and three dimensional viewing, will make it possible to observe fine surface structure of normal and pathological tissues. In the field of urology, the paper dealing with the study of the normal resting and stretched urethra and bladder mucosa by Lloyde-Davis et al. is one of a few available publications. The technique has been applied to the tumor pathology of the urinary tract by Fulker et al. who observed proliferative human bladder epithelium and bladder tumors. In the present study, normal and neoplastic materials of the human urinary bladder were obtained at the time of surgery. The specimens were feixed in 10% neutral formalin, dehydrated with graded alcohols and dipped in aceton, subsequently dried in air, coated with gold and examined by JSM-U3 and JSM-S1 type scanning electron microscope. All the tissues were also studied by light microscopy to ascertain histopathological identification.
