辽宁省由九个地区14个单位,使用GCH—1型宫腔测量器,对8217名健康妇女的宫腔底部横径进行了测量,结果宫底横径的平均值为3.08±0.34公分,最宽为5.0,最窄为1.0公分。横径的长短与年龄,身长,体重无关。未产妇较经产妇为小,但不随产次的增加而递增。横径与子宫内膜腔长无相关关系。因此,不能用子宫纵轴的深度测量来推算子宫腔底部的宽度,更不能单纯用测量宫腔长度作为放置宫内节育器型号大小的唯一标隹。
Liaoning Province, from 14 units in nine regions, the use of GCH-1 type uterine cavity measuring instrument, 8217 healthy women were measured at the bottom of the uterine diameter, the average diameter of the bottom of the palace of 3.08 ± 0.34 cm, the most Width of 5.0, the narrowest of 1.0 cm. The length of the diameter and age, length, weight has nothing to do. Unpaternal mothers than mothers for small, but not with the increase in production increases. There is no correlation between transverse diameter and endometrial cavity length. Therefore, we can not use the depth measurement of the uterine longitudinal axis to calculate the width of the bottom of the uterine cavity, but can not simply measure the length of the uterine cavity as the only standard size IUD placement.
