目的　观察阴道三维超声检查子宫内膜息肉的影像学特征 ,探讨本法诊断子宫内膜息肉的价值。方法　阴道三维超声结合宫腔注射生理盐水显像检查诊断子宫内膜息肉 2 5例 ,并全部在宫腔镜下切除新生物作病理组织学检查。结果　 2 5例阴道三维超声诊断子宫内膜息肉中有 2 4例与病理组织学符合 ,符合率为 96 %。结论　阴道三维超声结合子宫造影是诊断子宫内膜息肉简便可靠的方法。 Objective To observe the imaging features of vaginal three-dimensional ultrasonography in detecting endometrial polyps and to explore the value of this method in the diagnosis of endometrial polyps. Methods Twenty-five cases of endometrial polyps were diagnosed by intravaginal three-dimensional ultrasonography and intrauterine injection of saline, and all of them were removed by hysteroscopy for histopathological examination. Results Twenty-four cases of endometrial polyps diagnosed by vaginal three-dimensional ultrasonography were consistent with histopathology, and the coincidence rate was 96%. Conclusion Vaginal ultrasound combined with uterine angiography is a simple and reliable method to diagnose endometrial polyps.
