In the pros-tatic portion there is a gradual transition toward the flatstratified epithelium of the bladder. The cuboid andcolumnar epithelia from this portion come from the numer-ous glands opening into the prostatic Fig. 61.—Epithelia from the fossa navicularis. In chronic urethritis, large flat, horny epithelia, lookinglike vaginal, and practically of the same size as the latter,but with very small, round nuclei, appear in the urine, as aresult of the keratification of the urethral mucosa, whichis transformed in places frankly into the stratified squa-mous type. These cells, when numerous and when occur-ring in shred-like masses with pus, indicate the probabilityof stricture formation (see Fig. 80, B). 296 EXAMINATION OF THE URINE In the female the urethra is lined with a very variabletype of cells. In some women the squamous, in others thecolumnar, type predominates. The squamous cells aremost numerous toward both ends of the canal. As arule, squamous cells are most commonly found in thefemale urethra, while in the male, cylindric cells predomi-nate. The size of urethral cells in both male and female isabout three to five pus-cell diameters (in the longestdirection), though the squamous cells
