Investigate the association between pelvic floor muscle function and stress urinary incontinence (SUI) in women in the third trimester of pregnancy.
Cross-sectional observational study. Urinary symptoms were collected through a questionnaire. The physical examination of the pelvic floor muscle was performed by vaginal palpation and manometry. Multivariate logistic regression analyses were performed to investigate the factors associated with SUI.
Analysis of the data collected from nulliparous and multiparous women identified an association between decreased pelvic floor muscle function (i.e. Power, Repetition, and Maximal Voluntary Contraction (MVC)) and the presence of SUI. There were also associations noted between power and SUI [AOR (95% CI) = 1.41 (1.01-1.97)], repetition and SUI [AOR (95% CI) = 1.31 (1.06-1.63)], and MVC and SUI [AOR (95% CI) = 1.02 (1.00-1.03)]. In the analysis of nulliparous women, there was also an association between low resting vaginal pressure (manometry) and SUI [AOR (95% CI) = 1.03 (1.01-1.06)].
Low pelvic floor muscle strength, low MVC, and decreased ability to repeat sustained pelvic floor muscle contractions were associated with SUI in the third gestational trimester. In nulliparous women, there was an association between low resting vaginal pressure and SUI; however, none these associations were identified in multiparous women.
研究妊娠晚期女性盆底肌肉功能与压力性尿失禁（SUI）之间的关联。
横断面观察性研究。通过问卷调查收集泌尿症状。采用阴道触诊和压力测定法对盆底肌肉进行体格检查。进行多因素逻辑回归分析以研究与SUI相关的因素。
对初产妇和经产妇收集的数据进行分析，发现盆底肌肉功能下降（即力量、重复次数和最大自主收缩（MVC））与SUI的存在之间存在关联。力量与SUI之间也存在关联[AOR（95%CI）=1.41（1.01 - 1.97）]，重复次数与SUI之间存在关联[AOR（95%CI）=1.31（1.06 - 1.63）]，MVC与SUI之间存在关联[AOR（95%CI）=1.02（1.00 - 1.03）]。在对初产妇的分析中，静息阴道压力低（压力测定）与SUI之间也存在关联[AOR（95%CI）=1.03（1.01 - 1.06）]。
妊娠晚期盆底肌肉力量低、MVC低以及持续盆底肌肉收缩重复能力下降与SUI相关。在初产妇中，静息阴道压力低与SUI之间存在关联；然而，在经产妇中未发现这些关联。
