目的 探讨女性后盆腔三维超声断层图像(TUI)特点对肛门内括约肌损伤的评估临床价值。方法 回顾分析2015年5月 至2016年5月期间于我院就诊的共30例大便失禁女性患者，分别行经会阴三维超声断层成像(TUI)及直肠腔内彩超检 查，检查观察肛门内括约肌的形态、结构、厚度及连续性，了解肛门内括约肌损伤位置及程度，将两项超声检查结 果进行对照研究。结果 利用直肠腔内彩超检查诊断18例肛门内括约肌损伤，TUI技术诊断18例肛门内括约肌损伤， 提示TUI诊断功能内括约肌损伤程度的准确性与经直肠腔内彩超检查准确度相同，无统计学差异(P>0.05)。结论 TUI能完整显示肛门内括约肌形态、结构、厚度及连续性等，对肛门内括约肌损伤的诊断有一定应用价值。

Objective Discuss the female pelvic cavity after three dimensional ultrasound ct images (TUI) characteristics of anus sphincter injuries to evaluate the clinical value. Methods Retrospective analysis of 40 patients with Fecal incontinence. They during the period of treatment by acupuncture between May 2015 to May 2016 in our hospital and they were checked with three dimensional ultrasound ct images and rectal cavity colour to exceed examination. Comparing two ultrasound examination results. Results We diagnose the 18cases of anus sphincter damage with TUI,and diagnose the 18cases of anus sphincter damage with Rectal cavity colour to exceed examination. We deduce that the accuracy of the TUI is significantly higher than after rectal cavity colour to exceed examination. Conclusion TUI diagnosis of anus sphincter damage has a certain value.
