摘要
目的应用盆底三维超声观察妊娠晚期女性盆膈裂孔大小变化情况，为研究妊娠与盆底功能障碍性疾病之间的关系提供影像学依据。方法对20例正常未育女性及40例晚孕女性进行盆底三维超声检查，获得盆膈裂孔声像图，测量盆膈裂孔前后径、左右径和面积并进行两组对比，比较晚孕尿失禁组和晚孕无尿失禁组的盆膈裂孔前后径、左右径和面积。结果晚孕组盆膈裂孔前后径、左右径、面积均较正常未育组大（均P〈0．05）。晚孕尿失禁组和晚孕无尿失禁组间盆膈裂孔前后径、左右径、面积无明显差别（均P〉0．05）。结论稀底三维超声旱一种有效的观察奸娠期女性龠底支持系统的影像学方法。
Objective To study the variation of the urogenital hiatus dimension in late pregnancy women by three-dimensional（3D） pelvic floor ultrasonography, to provide imaging evidence in the study of the relationship between pregnancy and pelvic floor dysfunction diseases. Methods Twenty nulliparas and forty late pregnancy women were examined by 3D pelvic floor ultrasonography to obtain the image of urogenital hiatus in which anteroposterior diameter of urogenital hiatus （AP）, left to right diameter of urogenital hiatus （LR） and area of urogenital hiatus （HA） were measured and compared. AP, LR and HA were also compared between the late pregnancy women with stress urinary incontinence symptom and those without stress urinary incontinence symptom. Results AP, LR and HA in late pregnancy women were greater than those in nulliparas（all P 〈0.05） and had no difference between the late pregnancy women with stress urinary incontinence symptom and those without stress urinary incontinence symptom（all P 〉0.05）. Conclusions 3D pelvic floor ultrasonography is an effective imaging method to observe pelvic support in pregnancy women.
