目的:采用腔内三维超声对未孕妇女及经产妇女盆底结构进行对比观察,尽早发现女性盆底功能障碍性疾病。方法:选择2011年3月至2013年4月本院妇科门诊及住院未孕妇女及经阴道分娩妇女各60例为研究对象,于腔内阴道采用三维彩色超声诊断仪做盆底超声检查,分别测量安静及最大Valsalva动作后膀胱颈距耻骨联合下缘的垂直距离(BSD)、膀胱尿道后角(α)及肛提肌裂孔的面积,计算膀胱颈下降度(BND)。结果:妇女盆底肌松弛在经阴道分娩组中:轻度31%(19/60),中度11%(7/60),重度3%(2/60)。结论:采用腔内三维超声检查,观察经阴道分娩妇女盆底结构的改变,可早期诊断妇女盆底功能障碍性疾病,为临床制定防治策略提供可靠依据。

Objective:To compare the pelvic floor structures between pluripara and nullipara by using intracavity three-dimensional ultrasonography,which allows the early identification of pelvic floor dysfunction(PFD).Methods;Between March 2011 and April 2013,we performed intracavity three-dimensional ultrasonography for screening of PFD on pluripara(n = 60) and nullipara(n- 60) in the in-patient and outpatient clinics of Huizhou Third Peoples ' Hospital.This entailed measurement of bladder neck-symphyseal distance(BSD) during resting and following maximal Valsava's maneuver,retrovesical angle(a),the area of pelvic floor and the bladder neck descent(BND).Results:The proportion of PFD was 31%(19/60) for mild,11%(7/60) for moderate and 3%(2/60) for severe in patients who underwent vaginal deliver)'.Conclusion;By determination of the changes in pelvic floor structures,the intracavity three-dimensional ultrasonography may be a useful tool for early identification and offers reliable rationales for prevention and treatment of PFD.
