Clinical significance of three-dimensional pelvic floor ultrasound parameters in patients with stress urinary incontinence / 中国医师杂志

ABSTRACT

Objective:To explore the clinical significance of three-dimensional pelvic ultrasound parameters in patients with stress urinary incontinence (SUI).Methods:A total of 100 patients with SUI in the First Hospital Affiliated to Hunan Traditional Chinese Medical College from January 2018 to April 2020 were prospectively selected as the observation group, and 100 women who had undergone birth without SUI and other urinary system diseases who came for physical examination during the same period were selected as the control group. Comparing the three-dimensional pelvic floor ultrasound parameters of resting state and Valsalva action in the patients with different degrees of illness, the patients with different efficacy of the two groups and the observation group. Analyzing the correlation between three-dimensional pelvic floor ultrasound parameters and the severity and efficacy of SUI patients.Results:⑴ The posterior urethrovesical angel at rest and after Valsalva action, the pelvic diaphragmatic hiatus area after Valsalva action in the observation group were larger than those in the control group, and the puborectalis muscle thickness at rest and after Valsalva action was smaller than that of the control group, with statistically significant difference( P<0.05); ⑵ The posterior urethrovesical angel at rest and after Valsalva action, the pelvic diaphragmatic hiatus area at rest, and the puborectalis muscle thickness at rest and after Valsalva action were related to SUI ( P<0.05); ⑶ Comparison of patients with stress urinary incontinence of different severity the posterior urethrovesical angel at rest and after Valsalva action, the pelvic diaphragmatic hiatus area after Valsalva action mild<moderate<severe; the puborectalis muscle thickness at rest and after Valsalva action mild>moderate>severe; ⑷ After treatment, the posterior urethrovesical angel and pelvic diaphragmatic hiatus area of patients with poor curative effect at rest and after Valsalva action were larger than those of patients with good curative effect, and the puborectalis muscle thickness of patients with poor curative effect at rest and after Valsalva action was smaller than that of patients with good curative effect, with statistically significant difference ( P<0.05); ⑸ The posterior urethrovesical angel at rest and after Valsalva action, the pelvic diaphragmatic hiatus area after Valsalva action were positively correlated with the degree of disease and clinical efficacy, while the puborectalis muscle thickness was negatively correlated with the degree of disease and clinical efficacy at rest and after Valsalva action ( P<0.05). Conclusions:Three-dimensional pelvic floor ultrasound examination can effectively reflect the changes in pelvic floor structure of SUI patients under different action states, and provides important anatomical and functional basis for the judgment of SUI disease degree and the evaluation of curative effect.
