To describe the urethral course and position during urine leakage based on the visualized urethral mobility profile (UMP) and to explore the differences between supine and standing positions.
This was a prospective study of 100 women with SUI and 100 control women who underwent a cough stress test (CST) with transperineal ultrasound (TPUS) in supine and standing positions. In the mid-sagittal plane, the UMP software automatically placed six equidistant points from the bladder neck (point 1) to the external urethral meatus (point 6). It determined the x and y coordinates of the points relative to the symphysis pubis. The distance between the points and symphysis pubis (dist. 1 to 6) was calculated using the formula SQRT (x2 + y2). The visualized UMP was created by reproducing the six points on a bitmap.
Valid UMP data of 78 control women and 90 women with SUI were analyzed. In the two positions, distances 1 to 6 were significantly greater in the SUI group than the continent group (all p < 0.05). During Valsalva, the distance between the mid-urethra (dist. 3 and 4) and the symphysis was significantly increased (all p < 0.001) in the SUI group. The visualized UMP showed a similar upper-urethral course in the two groups. The gap between the mid-urethra (points 3 and 4) and symphysis was wider in the SUI group.
The visualized UMP in supine and standing positions showed no difference in the bladder neck and upper urethral stability between incontinent and continent women, but mid-urethral stability was weaker in SUI.
根据可视化尿道活动度图（UMP）描述尿失禁患者漏尿时的尿道走行和位置，并探讨仰卧位和站立位之间的差异。
这是一项前瞻性研究，共纳入 100 例压力性尿失禁（SUI）女性和 100 例对照女性，所有患者均接受经会阴超声（TPUS）下咳嗽压力试验（CST），分别在仰卧位和站立位下进行。在正中矢状面，UMP 软件自动在膀胱颈（点 1）和尿道外口（点 6）之间放置 6 个等距点。它确定了相对于耻骨联合的点的 x 和 y 坐标。使用公式 SQRT（x2 + y2）计算点与耻骨联合之间的距离（dist. 1 至 6）。通过在位图上再现这 6 个点来创建可视化 UMP。
分析了 78 例对照女性和 90 例 SUI 女性的有效 UMP 数据。在两个位置，SUI 组的距离 1 到 6 均显著大于对照组（均 p < 0.05）。在 Valsalva 期间，SUI 组的中尿道（dist. 3 和 4）与耻骨联合之间的距离显著增加（均 p < 0.001）。可视化 UMP 显示两组的上尿道走行相似。SUI 组中尿道中段（点 3 和 4）与耻骨联合之间的间隙更宽。
仰卧位和站立位下的可视化 UMP 显示，在有症状和无症状女性中，膀胱颈和上尿道稳定性没有差异，但 SUI 患者的中尿道稳定性较弱。
