To investigate pelvic floor muscle function and anatomy after childbirth in continent women differing in obstetric history.
Young, continent women, age range 20-40 years, were recruited into 3 groups: 1. elective, prelabor cesarean delivery (n =12); 2. vaginal delivery (n = 15); and 3. age-matched nulliparas as controls (n = 13). Pelvic floor muscle strength was measured by a perineometer and also assessed by vaginal palpation. Magnetic resonance imaging of the pelvic floor at rest and on maximal strain was performed. Statistical analysis was carried out using SPSS 10.0 (Chicago, Illinois) for Windows (Microsoft, Redmond, Washington); p < 0.05 was considered significant.
Pelvic floor muscle strength was not different between the vaginal delivery and cesarean groups. The descent of the bladder and cervix on straining was greater in the subjects who delivered vaginally than in the cesarean delivery and nulliparous groups. There was a positive and significant correlation between the duration of labor and the area of the levator sling and also between birth weight and the descent of the cervix on straining.
The results of this study show that delivery method does not affect pelvic muscle strength.
研究不同分娩史的无尿失禁女性产后盆底肌肉功能及解剖结构。
招募年龄在20 - 40岁的年轻无尿失禁女性，分为3组：1. 择期产前剖宫产（n = 12）；2. 阴道分娩（n = 15）；3. 年龄匹配的未产妇作为对照组（n = 13）。采用会阴压力计测量盆底肌肉力量，并通过阴道触诊进行评估。在静息状态和最大张力状态下对盆底进行磁共振成像。使用SPSS 10.0（伊利诺伊州芝加哥市）对Windows系统（华盛顿州雷德蒙德市微软公司）的数据进行统计分析；p < 0.05被认为具有统计学意义。
阴道分娩组和剖宫产组的盆底肌肉力量无差异。与剖宫产组和未产妇组相比，经阴道分娩的受试者在用力时膀胱和宫颈的下移程度更大。产程与提肌吊带面积之间以及出生体重与用力时宫颈下移程度之间存在正相关且具有统计学意义。
本研究结果表明分娩方式不影响盆底肌肉力量。
