Abstract: Objective To compare sonography image, hemodynamic characteristics and morphological changes of endometrial polypoid lesions and to discuss the value of sonography in diagnosis of endometrial polyps. Methods A total of 172 patients with a primary clinical diagnosis of endometrial polyps who underwent both transvaginal color Doppler sonography and pathology examinations were included. For sonography the lesion border, internal echo and distribution of blood signals were observed. The blood flow velocity and resistance index(RI) were measured. Lesions with clearly border and penetrate blood flow signals was the diagnostic criteria of endometrial polyps. For pathology, the structure and vascular supply of endometrial polyps were observed. Results Of the 172 patients, 68 cases had a pathological diagnosis of simple endometrial polyps, 3 cases of endometrial polyps were in combination with endometrial cancer, with 2 of them having malignant transformation, 63 cases of endometrial hyperplasia, 27 cases had secretory endometrium, 7 cases had proliferative endometrium, 3 cases had submucosal uterine fibroids, 1 case had endometritis. The agreement rate between sonography and pathology was 85.91%(61/71) for establishing the diagnosis of endometrial polyps, and 81.19%(82/101) for excluding the diagnosis. The total agreement rate was 83.14%. Conclusion Intrauterine lesions with penetrate or point-like flow is the diagnostic indications of endometrial polypoid lesions using sonography. Hysteroscopic biopsy has a significant role in differential diagnosis of benign and malignant polypoid lesions.
