Clinical Value of Pelvic Floor Ultrasound and Glazer Pelvic Floor Electromyography in Predicting Postpartum Stress Urinary Incontinence

Abstract：Objective:Based on pelvic floor ultrasound and Glazer pelvic floor surface electromyography parameters in postpartum patients with stress urinary incontinence (SUI), to establish a model and explore its clinical value in predicting the disease.Methods:A total of 193 postpartum women admitted to our hospital were enrolled and divided into the SUI group (67 cases) and non-SUI group (126 cases) according to the occurrence of SUI at 6-8 weeks postpartum．Clinical data, three-dimensional pelvic floor ultrasound parameters，and Glazer pelvic floor sEMG parameters were collected from both groups．Univariate and multivariate analyses were performed to screen independent factors，based on which a nomogram model was established. Receiver operating characteristic (ROC) curves and clinical decision curves were plotted．Results：Significant differences were observed between the two groups in neonatal body weight，maternal weight at follow-up, bladder neck mobility (BNM)，urethral rotation angle(URA), posterior vesicourethral angle(PVA)，levator hiatus area(LHA) ，pelvic floor fast contraction force，tonic contraction force，and endurance (all P
