Urethrocytograms were made by brushing in women during the last quarter of their pregnancy, from week 28 of amenorrhea to week 38. Two different cell patterns were present in these smears. The A-pattern is composed by round squamous cells, often in clumps. The B-one is characterized by small clusters of more irregular polygonal squamous cells. The A-pattern was more frequent until week 32; the B-pattern was predominant in further smears until week 38. The presence of the A- and B-patterns in the smears may cause confusion for the cytologist respectively with the at-term- and near-term-patterns. The authors emphasize the interest of these studies in the early deliveries.
在妊娠最后三个月（从停经第28周到第38周）的女性中，通过刷片法制作尿道细胞涂片。这些涂片中存在两种不同的细胞模式。A模式由圆形鳞状细胞组成，常聚集成团。B模式的特征是有小簇更不规则的多边形鳞状细胞。直到第32周，A模式更为常见；在接下来的涂片直至第38周，B模式占主导。涂片中A模式和B模式的存在可能分别使细胞学家将其与足月模式和近足月模式相混淆。作者强调了这些研究在早产方面的意义。
