These studies concern the topographic distribution of epithelia along the first 10 millimeters of the urethra after the meatus. The results are obtained by microscopical examination of 100 smears of this area and of histological sections of 5 urethral specimens removed at routine autopsy examination. The cells of 2 epithelia -- nonkeratinizing stratified squamous epithelium and stratified columnar epithelium -- are common on urethral smears; the other epithelial cells (metaplastic squamous cells, mucosal cells, anucleated cells) are less frequent or exceptional. On 91 smears of volunteers, 16 smears have no columnar cells and the other 75 smears have percentages of whole columnar cells going from 1 to 96,5% of whole epithelial cells. The number of clusters of each epithelium is very few. Microscopical examination of histological sections reveals the presence : (a) of nonkeratinizing squamous epithelium with/without leucokeratosis in 3 cases; (b) of squamous and columnar epithelia with areas of metaplastic squamous epithelium for the other 2 specimens. The significance of these results is discussed.
这些研究关注尿道口后尿道前10毫米处上皮的地形分布。结果是通过对该区域的100份涂片以及在常规尸检中取出的5份尿道标本的组织切片进行显微镜检查获得的。在尿道涂片上常见两种上皮细胞——非角化复层鳞状上皮和复层柱状上皮；其他上皮细胞（化生鳞状细胞、黏膜细胞、无核细胞）则较少见或罕见。在91名志愿者的涂片上，16份涂片没有柱状细胞，其他75份涂片的柱状细胞占全部上皮细胞的比例从1%到96.5%不等。每种上皮细胞的细胞簇数量很少。对组织切片的显微镜检查显示：（a）3例中有非角化鳞状上皮，伴有或不伴有白色角化病；（b）另外2例标本中有鳞状上皮和柱状上皮，伴有化生鳞状上皮区域。讨论了这些结果的意义。
