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.
