Correlation between three-dimensional transperineal ultrasound and pelvic floor electromyography in women with stress urinary incontinence

Objectives: To investigate the relationships among pelvic floor myoelectric level, ultrasound and stress urinary incontinence in women.

Material and methods: 218 women with SUI and 300 normal women were studied. The main outcomes were to determine the relationship between SUI and high-risk factors, PFM intensity, pelvic floor EMG value, and pelvic floor ultrasound data.

Results: In the pelvic floor EMG data, the abnormal rate of type I muscle fibre strength, type I muscle fibre fatigue, type II muscle fibre strength and type II muscle fibre endurance in the SUI group reached more than 50%. The abnormal rates of type I muscle fibre strength and type II muscle fibre strength in the severe SUI group were more significant than those in the mild and moderate SUI. The funnelization of the black neck urethra, bladder neck mobility, posterior angle of the black neck urethra, urinary increment angle and urinary rotation angle of the SUI group were significantly increased. The levator ani muscle in the SUI group was thinner, and the difference was statistically significant. The analysis of the variance results of the overall significance of the regression model were tested, and the final multiple linear regression model was statistically significant.

Conclusions: With the help of a convenient and economic means of the early detection of SUI, the diagnosis rate can be improved so that SUI tendency can achieve a diagnosis and treatment through nonsurgical treatment with fewer complications and a low risk and improve the quality of life of middle-aged and elderly women.
