To determine the normal range of uterine cervix within 4-24 weeks of pregnancy and also assess whether variations are related to some selected extraneous human conditions.
This was a prospective study conducted in University of Benin Teaching Hospital, Benin, Nigeria, and Nigerian National Petroleum Cooperation Health Centre, Warri, Nigeria.
A prospective ultrasonographic (USS) study of uterine cervical dimension of 150 pregnant women within 4-24 weeks gestational age in two sonographic centers in Nigeria between January 2007 and October 2007 was conducted. The patients were examined by the authors. The uterine cervical dimensions (length, upper lip diameter, and lower lip diameter) were taken by means of ultrasonography. In addition, vital history, height and weight of patients were documented. The vital history included the age, number of childbirths, number of induced abortion, miscarriages and family history of miscarriages. Using Statistical program of social science (SPSS), the data were analyzed. Informed consent was obtained from all the patients and the study was done in line with the ethical guidelines of the centers.
The following uterine cervical dimensions were obtained: mean cervical length of 6.14 cm and standard deviation of 2.0, and the upper and lower lips' uterine cervical diameters of 1.81 and 1.76 cm, respectively, with standard deviations of 0.86 and 0.71, respectively. There was no significant correlation of dimensions of uterine cervix to the aforementioned extraneous human condition. However, the increasing number of miscarriages correlated with decreasing length or shortness of the cervix.
Uterine cervical dimension in pregnancy between 4 and 24 weeks is reproducible with sonographic documentation and the following normal ranges were deduced: cervical length (6.14 ± 2.0 cm), upper lip (1.81 ± 0.86 cm) and lower lip (1.76 ± 0.71 cm). The study revealed that increasing number of miscarriages was associated with effacement or reduction in the cervical length.
确定妊娠4至24周子宫颈的正常范围，并评估其变化是否与某些选定的外部人体状况相关。
这是一项前瞻性研究，在尼日利亚贝宁的贝宁大学教学医院以及尼日利亚瓦里的尼日利亚国家石油公司健康中心开展。
2007年1月至2007年10月期间，在尼日利亚的两个超声检查中心，对150名孕龄在4至24周的孕妇进行子宫颈尺寸的前瞻性超声检查（USS）研究。由作者对患者进行检查。通过超声检查测量子宫颈尺寸（长度、上唇直径和下唇直径）。此外，记录患者的重要病史、身高和体重。重要病史包括年龄、分娩次数、人工流产次数、自然流产次数以及自然流产家族史。使用社会科学统计程序（SPSS）对数据进行分析。所有患者均获得知情同意，且研究遵循各中心的伦理准则进行。
获得以下子宫颈尺寸数据：宫颈平均长度为6.14厘米，标准差为2.0；子宫颈上唇和下唇直径分别为1.81厘米和1.76厘米，标准差分别为0.86和0.71。子宫颈尺寸与上述外部人体状况无显著相关性。然而，自然流产次数增加与宫颈长度缩短相关。
妊娠4至24周期间子宫颈尺寸可通过超声记录重现，并得出以下正常范围：宫颈长度（6.14±2.0厘米）、上唇（1.81±0.86厘米）和下唇（1.76±0.71厘米）。研究表明，自然流产次数增加与宫颈消退或长度缩短有关。
