Application value of transvaginal ultrasound in the diagnosis of common causes of secondary dysmenorrhea
经阴道超声在继发性痛经病因诊断中的应用价值研究

摘要

目的 探讨经阴道超声在继发性痛经常见病因中的诊断效能。方法 选择2025年1月至2025年12月在我院妇科就诊的继发性痛经患者80例作为观察组，同期选取在我院进行健康体检的非痛经女性80例作为对照组。均接受经阴道超声检查，记录影像学特征，统计观察组中子宫腺肌症、卵巢巧克力囊肿、较大黏膜下子宫肌瘤等器质性病变的检出率。结果 观察组80例继发性痛经患者中，经阴道超声检出子宫腺肌症37例、卵巢巧克力囊肿25例、较大黏膜下子宫肌瘤18例，通过检查确诊数量为70例，总检出率为87.5%（70/80）。结论 经阴道超声可清晰显示继发性痛经患者盆腔器官的形态学改变，可作为继发性痛经病因筛查的首选影像学方法。

Abstract

Objective To explore the diagnostic efficacy of transvaginal ultrasound in common causes of secondary dysmenorrhea.
Methods 80 patients with secondary dysmenorrhea who visited the gynecology department of our hospital from January 2025 to December 2025 were selected as the observation group, and 80 non-dysmenorrhea women who underwent health check-ups in our hospital during the same period were selected as the control group. All patients underwent transvaginal ultrasound examination, and the imaging features were recorded. The detection rates of organic lesions such as uterine adenomyosis, ovarian chocolate cysts, and large submucosal fibroids in the observation group were statistically analyzed.
Results Among the 80 patients with secondary dysmenorrhea in the observation group, transvaginal ultrasound detected 37 cases of uterine adenomyosis, 25 cases of ovarian chocolate cysts, and 18 cases of large submucosal fibroids. The number of cases confirmed through the examination was 70, and the total detection rate was 87.5% (70/80).
Conclusion   Transvaginal ultrasound can clearly display the morphological changes of pelvic organs in patients with secondary dysmenorrhea and can be used as the preferred imaging method for screening the causes of secondary dysmenorrhea.
