Evaluate the Clinical Curative Effect of Biofeedback Electrical Stimulation Combined with Pelvic Floor Muscle Exercise in the Treatment of Postpartum Pelvic Floor Dysfunction Based on Transperineal Real-time Three-dimensional Ultrasound
Objective:To explore the clinical curative effect of transperineal real-time three-dimensional ultrasound evaluation of biofeedback electrical stimulation combine with pelvic floor muscle exercise in the treatment of postpartum pelvic floor dysfunction.Methods:96 postpartum pelvic floor dysfunction patients who were admitted to our hospital from September 2020 to September 2022 were selected,the patients were divided into two groups according to the random number table method,control group(48 cases)received pelvic floor muscle exercise treatment,study group(48 cases)treated with biofeedback electrical stimulation combined with pelvic floor muscle exercise.Transperineal real-time three-dimensional ultrasound examination before treatment and after treatment,the pelvic floor distress inventory(PFDI-20)scores,pelvic floor dysfunction impact simple questionnaire 7(PFIQ-7)scores,rest and valsalva action states ultrasound parameters of levator ani muscle were compared between two groups before treatment and after treatment.The correlation between ultrasound parameters of levator ani muscle and PFDI-20 and PFIQ-7 scores were analyzed.Results:The scores of PFDI-20 and PFIQ-7,the anterior and posterior diameters of levator ani muscle hiatus,left and right diameters of levator ani muscle hiatus and the area of levator ani muscle hiatus at rest and Valsalva action states in two groups after treatment were lower than those before treatment(P＜0.05),the thickness of levator ani muscle at rest state was increased compared with that before treatment(P＜0.05).The scores of PFDI-20 and PFIQ-7,the anterior and posterior diameters of levator ani muscle hiatus,left and right diameters of levator ani muscle hiatus and the area of levator ani muscle hiatus at rest and Valsalva action states in study group after treatment were lower than those in control group(P＜0.05),the thickness of levator ani muscle at rest state was greater than that in control group(P＜0.05).The anterior and posterior diameters of levator ani muscle hiatus,left and right diameters of levator ani muscle hiatus and the area of levator ani muscle hiatus at rest and Valsalva action states were positively correlated with PFDI-20 and PFIQ-7 scores(P＜0.05),the thickness of levator ani muscle at rest state were negatively correlated with PFDI-20 and PFIQ-7 scores(P＜0.05).Conclusion:The size of levator ani muscle hiatus decrease after the treatment of biofeedback electrical stimulation combine with pelvic floor muscle exercise compare with before treatment,the thickness of the levator ani muscle increase compare with before treatment,and it is related to the improvement of PFDI-20 and PFIQ-7 scores,transperineal real time three-dimensional ultrasound can objectively and effectively evaluate the treatment effect of postpartum pelvic floor dysfunction patients.
