目的 探讨在临床诊断剖宫产术后子宫切口憩室中应用经阴道超声诊断技术的价值。方法 选择深圳市坪山区人民医院2016年6月—2019年12月收治的80例疑似剖宫产术后子宫切口憩室患者作为研究对象,分别对其进行腹部超声诊断、经阴道超声诊断,以宫腔镜作为金标准,比较经阴道超声和腹部超声的诊断符合率、特异度以及灵敏度。结果 经阴道超声诊断灵敏度、特异度、符合率分别为87.50%、85.42%、86.25%,高于腹部超声的62.50%、62.50%、62.50%,差异具有统计学意义（P<0.05）。结论 采用经阴道超声诊断剖宫产术后子宫切口憩室具有较高灵敏度、特异度,对临床提高子宫憩室诊断准确率具有积极意义。

Objective To explore the value of transvaginal ultrasound in the clinical diagnosis of uterine incision diverticulum after cesarean section. Methods Eighty patients with suspected uterine incision diverticulum after cesarean section in Pingshan People’s Hospital of Shenzhen from June 2016 to December 2019 were selected as study subjects. Abdominal ultrasound diagnosis and transvaginal ultrasound diagnosis were performed respectively.Hysteroscopy was used as the gold standard to compare the diagnostic agreement rate, specificity, and sensitivity of transvaginal ultrasound and abdominal ultrasound. Results The diagnostic sensitivity, specificity, and agreement rate of transvaginal ultrasound were 87.50%, 85.42%, and 86.25%, respectively, higher than those of abdominal ultrasound （62.50%, 62.50%, and 62.50%, respectively）, with statistically significant differences （P<0.05）. Conclusion Transvaginal ultrasound in the diagnosis of uterine incision diverticulum after cesarean section has high sensitivity and specificity, and has positive significance for improving the diagnostic accuracy of uterine diverticulum.
