目的:探讨经阴道彩色超声对绝经后子宫内膜病变的诊断价值。方法:采用经阴道彩色超声回顾性观察200例绝经后子宫出血患者的超声图像特征、子宫内膜厚度及血流阻力指数。结果:子宫内膜癌的内膜厚度明显高于子宫良性病变的内膜厚度,且子宫内膜癌的内膜厚度均>5 mm;子宫内膜癌的血流阻力指数明显低于良性病变,两项均有统计学差异(P<0.05)。结论:经阴道彩色超声检查是诊断子宫内膜疾病的常规首选方法。 Objective: To investigate the value of transvaginal color ultrasound in the diagnosis of postmenopausal endometrial lesions. Methods: Ultrasonographic features, endometrial thickness and blood flow resistance index were retrospectively studied in 200 cases of postmenopausal uterine bleeding by transvaginal sonography. Results: The endometrial thickness of endometrial carcinoma was significantly higher than that of benign uterine lesions, and the endometrial thickness of endometrial carcinoma were> 5 mm. The endometrial carcinoma blood flow resistance index was significantly lower than that of benign lesions, There was a statistically significant difference between the two groups (P <0.05). Conclusion: Transvaginal color sonography is the routine method of choice for the diagnosis of endometrial diseases.
