围绝经期女性压力性尿失禁的盆底肌电生理分析

Assessment of pelvic floor electrophysiology in perimenopausal women with stress urinary incontinence

目的研究围绝期女性压力性尿失禁(SUI)与盆底肌电生理参数的关系。方法采用PHENIX神经肌肉刺激治疗仪测定520例围绝经期妇女的盆底肌最大肌电位和Ⅰ、Ⅱ型肌纤维耐力等指标,分析其与SUI的关系。结果SUI的发生率为53.85%(280/520)。与非SUI妇女相比,SUI患者的盆底最大肌电位和Ⅰ、Ⅱ型肌纤维耐力均有下降趋势[(11.47±4.34)μV vs.(11.82±4.40)μV和(2.30±1.63)级vs.(2.32±1.80)级、(1.75±1.48)级vs.(1.81±1.60)级](P>0.05)。Logistic回归分析显示,盆底肌电参数与SUI的发生无明显相关性(P>0.05)。结论围绝经期女性发生SUI与盆底肌电生理参数无明显相关性。

Objective To investigate the relationship of stress urinary incontinence（SUI）and surface electromyography（sEMG）of pelvic floor muscles（PFMs）in perimenopausal women.Methods The criteria of sEMG of PFMs were measured in 520 perimenopausal women with PHENIX Neuromuscular Electrical Stimulation Therapy System（France）,of whom 280 cases were with SUI.The relationship of SUI and sEMG of PFMs was analyzed.Results The incidence rate of SUI was53.85%（280/520）.Compared to the women without SUI,the women with SUI had a tendency of decrease in the maximal potential[（11.47±4.34）μV vs.（11.82±4.40）μV]and the maximal endurance of PFMs contraction for typeⅠandⅡmuscle fibres[（2.30±1.63）grades vs.（2.32±1.80）grades and（1.75±1.48）grades vs.（1.81±1.60）grades]（P〉0.05）.Logistic regression analysis showed that sEMG of PFMs was not significantly correlated to SUI（P〉0.05）.Conclusion There is no significant correlation between SUI and sEMG of PFMs in perimenopausal women.
