目的 了解B超影像检测不同分期宫颈癌患者宫颈大小的范围,为临床从客观数据推测临床分期提供循证学数据.方法 行根治性手术的不同分期宫颈癌患者的167例,观察B超影像检测宫颈大小平均值及90％分布区间范围的大小值.结果 Ⅰ期宫颈癌最大径线平均值为3.42 cm,90％分布区间为2.5～4.5 cm,Ⅱa期宫颈癌最大径线平均值为4.16cm,90％分布区间为4.0～5.6 cm.结论 宫颈B超影像检测宫颈癌大小在4.5 cm以上者,临床诊断分期以Ⅱ期以上更多见.%Objective To observe cervix size in different-stages of uterine cervical cancer through B-ultra-sound, and to supply objective evidence-based data for clinical staging. Methods 167 patients receiving radical operation in different-stages of uterine cervical cancer were detected through B-ultrasound for average cervix size and 90% distribution scopes. Results For stage I uterine cervical cancer, the maximum average size was 3.42 cm and 90% distribution scope was 2.5~4.5 cm. For stage Ⅱ a uterine cervical cancer, the maximum average size was 4.16 cm and 90% distribution scope was 4.0~5.6 cm. Conclusion It is mostly diagnosed as stage Ⅱ uterine cervical cancer for those with cervix size above 4.5 cm.
