目的:探讨盆底超声联合肌电生理参数对初产妇不同程度产后压力性尿失禁(SUI)和盆底功能的诊断价值.方法:选取2019年1月至2022年1月在昆明市延安医院产科就诊的160例SUI患者,根据盆底功能(不同肌纤维的肌电压值)将其分为异常组(110例)和正常组(50例),参照中国泌尿外科疾病诊断指南和国际尿失禁咨询委员会尿失禁问卷简表(ICI-Q-SF)对SUI进行分级,观察静息时膀胱尿道后角(α)、静息至乏式动作后膀胱颈y轴位移(△y)和x轴位移(△x)、静息至乏式动作后近端尿道旋转角(γ)以及乏式动作后膀胱尿道后角(β),运用肌电图描记法描记两组患者前基线平静期、Ⅱ类肌纤维收缩期、Ⅱ和Ⅰ类肌纤维收缩期、Ⅰ类肌纤维收缩期及后基线平静期的盆底肌电活动信号,量化其盆底表面不同肌纤维的肌电压值.结果:不同程度产后SUI患者的△x比较差异无统计学意义.不同程度产后SUI患者△y、α、β及γ比较差异均有统计学意义(F=7.162、7.655、14.998、2.758,P＜0.05);不同程度产后SUI患者的前基线、后基线平静期以及Ⅰ类肌纤维收缩期肌电压均值比较差异均无统计学意义,不同程度产后SUI患者的Ⅱ类、Ⅱ和Ⅰ类肌纤维收缩期肌电压均值比较差异均有统计学意义(F=12.062、24.501,P＜0.05);两组△x比较无统计学差异.异常组△y、α、β及γ均明显高于正常组,差异有统计学意义(t=8.991、8.691、9.389、27.552,P＜0.05);两组前基线、后基线平静期,Ⅰ类肌纤维收缩期肌电压均值比较均无统计学差异,异常组Ⅱ类、Ⅱ和Ⅰ类肌纤维收缩期肌电压均值均明显高于正常组,差异有统计学意义(t=9.613、14.452,P＜0.05);盆底超声、肌电生理参数诊断初产妇不同程度产后SUI的△y、α、β、γ、Ⅱ类肌纤维收缩期均值、Ⅱ和Ⅰ类肌纤维收缩期均值的灵敏度分别为71.60%、79.40%、81.40%、91.20%、83.30%和82.40%,特异度分别为41.40%、37.90%、37.90%、60.30%、41.40%和44.80%,联合诊断的灵敏度和特异度分别为92.20%和82.80%;盆底超声、肌电生理参数诊断初产妇盆底功能的△y、α、β、γ、Ⅱ类肌纤维收缩期均值、Ⅱ和Ⅰ类肌纤维收缩期均值的灵敏度分别为79.10%、77.30%、88.20%、89.10%、77.30%和87.30%,特异度分别为64.00%、64.00%、52.00%、46.00%、70.00%和66.00%,联合诊断的灵敏度和特异度分别为98.20%、80.00%.结论:盆底肌电生理参数与盆底超声参数在诊断不同程度产后SUI和盆底功能具有一定的价值,且联合诊断的价值更高.
Abstract
Objective:To investigate the diagnostic value of pelvic floor ultrasound combined with electromyography physiological parameters for postpartum stress urinary incontinence(SUI)of different degrees and pelvic floor function of primipara.Methods:A total of 160 SUI patients who admitted to Yan'an hospital of Kunming City from January 2019 to January 2022 were selected,and they were divided into abnormal group(110 cases)and normal group(50 cases)according to pelvic floor function(the muscle voltage values of different muscle fibers).The SUI was graded according to the Chinese Guidelines for Diagnosis of Urological Diseases and the International Incontinence Advisory Committee's Incontinence Questionnaire(ICI-Q-SF).The posterior horn(α)of bladder and urethra at rest,the displacements of the bladder neck on y-axis(△y)and x-axis(△x)after the rest to the fatigue action,the proximal urethral rotation angle after the rest to the fatigue action(γ),the posterior horn of bladder and urethra(β)after the fatigue action were observed.The electromyography was used to draw and record the pelvic floor myoelectric activity signals of the patients of two groups at five stages(pre baseline rest period,class II muscle fiber systole period,class II and I muscle fiber systole period,class I muscle fiber systole period and post baseline rest period).And then,the muscle voltage values of different muscle fibers on the surface of pelvic floor were quantified.Results:There was no statistically significant difference in Δ x between patients with postpartum SUI of different degrees.There were significant differences in △y,α,β and γ between patients with postpartum SUI of different degrees(F=7.162,7.655,14.998,2.758,P<0.05).The differences of the means of muscle voltages of pre and post baseline rest period,and class I muscle fiber systole period among patients with postpartum SUI of different degrees were not significant.The differences of the means of muscle voltages of class II,and the class II and I muscle fiber systole period among patients with postpartum SUI of different degrees were significant(F=12.062,24.501,P<0.05),respectively.There was no statistically significant difference in △x between the two groups.The △y,α,β and γ of abnormal group were significantly higher than those of normal group(t=8.991,8.691,9.389,27.552,P<0.05),respectively.There were no statistically significant differences in the means of muscle voltage values of the pre and post baseline rest period,and class I muscle fibers systole period between the two groups.The means of muscle voltage values of class II,and class II and I muscle fibers systole period in the abnormal group was significantly higher than them in the normal group(t=9.613,14.452,P<0.05),respectively.The sensitivities of △y,α,β,γ,the means of class II muscle fibers systole period,and the means of class II and I muscle fibers systole period of pelvic floor ultrasound and electromyography physiological parameters were respectively 71.60%,79.40%,81.40%,91.20%,83.30%and 82.40%,and the specificities of them were respectively 41.40%,37.90%,37.90%,60.30%,41.40%,and 44.80%in diagnosing postpartum SUI of different degrees of primipara.The sensitivity and specificity of the combined diagnosis of them were respectively 92.20%and 82.80%in diagnosing postpartum SUI of different degrees of primipara.The sensitivities of △y,α,β,γ,the means of class II muscle fibers systole period,and the means of class II and I muscle fibers systole period of pelvic floor ultrasound and electromyography physiological parameters were respectively 79.10%,77.30%,88.20%,89.10%,77.30%,87.30%,and the specificities of them were respectively 64.00%,64.00%,52.00%,46.00%,70.00%and 66.00%in diagnosing pelvic floor function of primipara.The sensitivity and specificity of the combined diagnosis were respectively 98.20%and 80.00%in diagnosing pelvic floor function of primipara.Conclusion:Pelvic floor electromyography physiological parameters and pelvic floor ultrasonic parameters have a certain value in diagnosing postpartum SUI of different degrees and pelvic floor function,and the value of the combined diagnosis of them is higher.
