Colposcopy was first introduced in 1925 in Germany by Hans Hinselman. A colposcopeworks on the hypothesis that by magnifying the cervix and applying good illumination, early stages of cervical cancer could be picked -up. Other workers in the field include Schiller, Papanicolou, and Ayres who all contributed to the early detection of cervical cancer. The basic issue is the transformation zone (TZ). It is an area that forms from squamous metaplasia of columnar epithelium. The area where the two epithelia meet is referred to as the squamo-columnar junction SCJ. It is the most important landmark in cytology and colposcopy, where 90% of cervical neoplasm originates. More units are incorporating colposcopy into their practice so as to improve care of women with abnormal smears. Therefore, understanding of the scientific basis of colposcopy is important in carrying out the procedure according to agreed international standards.
阴道镜检查于1925年由汉斯·欣塞尔曼在德国首次引入。阴道镜的工作原理是通过放大宫颈并提供良好的照明，来发现宫颈癌的早期阶段。该领域的其他工作者包括席勒、帕帕尼科拉乌和艾尔斯，他们都为宫颈癌的早期检测做出了贡献。基本问题是转化区（TZ）。它是由柱状上皮鳞状化生形成的区域。两种上皮相遇的区域称为鳞柱交界（SCJ）。它是细胞学和阴道镜检查中最重要的标志，90%的宫颈肿瘤起源于此。越来越多的医疗机构将阴道镜检查纳入其实践中，以改善对涂片异常女性的护理。因此，了解阴道镜检查的科学基础对于按照公认的国际标准进行该操作很重要。
