| 目的 应用盆底超声评估静息、缩肛和Valsalva状态下肛直肠角（ARA）及其变化，探讨其与子宫脱垂程度的关系。方法 收集于我院行盆底超声检查的女性131例，根据子宫脱垂程度分为无脱垂组（47例）、Ⅰ度脱垂组（40例）和Ⅱ度及以上脱垂组（44例）。应用盆底超声测量各组静息、缩肛和Valsalva状态下ARA，比较各组不同状态下ARA及其变化，分析其与子宫脱垂程度的关系。结果 无脱垂组、Ⅰ度脱垂组和Ⅱ度及以上脱垂组vARA、Valsalva状态下ARA变化比较，差异有统计学意义（均P＜0.001）。与无脱垂组比较，Ⅰ度脱垂组vARA较小，Ⅱ度及以上脱垂组vARA较大，差异均有统计学意义（均P＜0.05）；与Ⅰ度脱垂组比较，Ⅱ度及以上脱垂组vARA较大，差异有统计学意义（P＜0.05）。Valsalva动作时Ⅰ度脱垂组ARA变小，无脱垂组和Ⅱ度及以上脱垂组ARA变大（P＜0.001），且Ⅱ度及以上脱垂组ARA变大较无脱垂组更明显（P=0.004）。结论 应用盆底超声可以评估不同程度子宫脱垂患者ARA及其变化，其中Valsalva状态下ARA及其变化与子宫脱垂程度有关，有一定的临床价值。 |

| Abstract: |
| Objective To evaluate the anorectal angle (ARA) and its changes at rest, during contraction and Valsalva maneuver by pelvic floor ultrasound. And to explore its relationship with the degree of uterine prolapse.Methods A total of 131 women who underwent pelvic floor ultrasound examination in our hospital were divided into no prolapse group (47 cases), stage I prolapse group (40 cases), and stage II or above prolapse group (44 cases) based on the degree of uterine prolapse. Pelvic floor ultrasound was used to measure ARA at rest, during contraction and Valsalva maneuver in each group. ARA and its changes in different states were compared, and its relationship with the degree of uterine prolapse was analyzed.Results There was a statistically significant difference in vARA and ARA changes during Valsalva maneuver among the three groups (all P＜0.001). Compared with the no prolapse group, the vARA of the stage I prolapse group decreased, while the vARA of the stage II or above prolapse group increased, with statistical significance (both P＜0.05). Compared with the stage I prolapse group, the vARA of the stage II or above prolapse group increased, with statistical significance (P＜0.05). During Valsalva maneuver，ARA decreased in the stage Ⅰ group，and increased in the no prolapse group and the stage Ⅱ group（both P＜0.001）.ARA increased more in the stage II group（P=0.004）.Conclusion The application of pelvic floor ultrasound can evaluate the ARA and its changes in patients with varying degrees of uterine prolapse. ARA and its changes in Valsalva maneuver are related to the degree of uterine prolapse and have certain clinical value. |
