盆底超声影像在妇女压力性尿失禁中的临床应用

目的 探讨妇女压力性尿失禁的盆底超声影像特征，为提高压力性尿失禁患者的临床疗效提供理 论依据。方法 选取2015 年3 月—2017 年3 月于深圳市第六人民医院门诊及住院治疗的压力性尿失禁妇女 98 例作为研究组，选取同期在该院健康体检的妇女98 例作为对照组，采集患者静息状态下以及Valsalva 状态 下的二维、三维的图像，将图像收集后采用多普勒超声原装软件进行分析。结果 研究组静息状态下尿道倾 斜度、膀胱尿道后角小于对照组（P <0.05），研究组肛提肌裂孔面积大于对照组（P <0.05）。研究组Valsalva 状态下膀胱位置、膀胱颈位置低于对照组（P <0.05），研究组尿道倾斜度、膀胱尿道后角和肛提肌裂孔面积 高于对照组（P <0.05）。研究组膀胱颈移动度、尿道旋转角大于对照组（P <0.05）。研究组尿道口漏斗形成 率高于对照组（P <0.05）。结论 盆底超声影像技术可以有效鉴别压力性尿失禁盆底形态的改变。压力性尿 失禁的发生与尿道、膀胱颈及肛提肌等支持结构的缺陷存在密切的联系。

Clinical application of pelvic floor ultrasound imaging in women with stress urinary incontinence

Objective To investigate pelvic ultrasound imaging features of stress incontinence in women, and to lay a scientific foundation for clinical improvement of the efficacy of patients with stress urinary incontinence. Methods A total of 98 stress urinary incontinence patients in our hospital and in hospital from March 2015 to March 2017 were selected as the study group. The same period in our hospital in the health examination of 98 women were selected as a control group. Two-dimensional and three-dimensional images of the patient at rest and in the Valsalva state were collected, and the images were collected using Doppler ultrasound original software for analysis. Results The inclination of urethra and the posterior angle of bladder urethra in the study group were lower than those in the control group (P < 0.05), and the area of levator ani muscle cleft in the study group was larger than that in the control group (P < 0.05). The bladder position and bladder neck position in the study group were lower than those in the control group (P < 0.05), and the urethra inclination, posterior angle of bladder urethra and the area of levator ani muscle cleft in the study group were higher than those in the control group (P < 0.05). The mobility of bladder neck and the rotation angle of urethra in the study group were higher than those in the control group (P < 0.05). The formation rate of urethral funnel in the study group was higher than that in the control group (P < 0.05). Conclusions Pelvic floor ultrasound imaging can effectively identify changes in pelvic floor morphology of stress urinary incontinence. The occurrence of stress incontinence is closely related to the defects of supporting structures such as urethra, bladder neck and levator ani muscle.
