Abstract To investigate the efficacy of transvaginal ultrasound combined with contrast-enhanced ultrasound(CEUS) for diagnosing the uterine myoma. Methods: The clinical data of 112 patients with uterine myomas confirmed by surgery and pathology who were admitted to the hospital from January 2021 to January 2023 were analyzed retrospectively. All patients were given the examination by transvaginal ultrasound and CEUS. The results of the examination by transvaginal ultrasound and CEUS of the patients were compared with their pathological results. The value of transvaginal ultrasound or CEUS alone, or the combination of transvaginal ultrasound and CEUS of the patients for diagnosing their uterine myoma was analyzed. Results: In 112 patients with uterine myomas, there were 72 cases with type Ⅰ of uterine myomas and 40 cases with type Ⅱ of uterine myomas, there were 21 cases with submucosal leiomyoma, 62 cases with intramural leiomyoma and 29 cases with subserous leiomyoma, and there were 58 cases with single leiomyoma and 54 cases with multiple leiomyoma. A total of 173 lesions of the uterine myomas of the patients were found, including 25 lesions of submucosal myomas, 112 lesions of intramural leiomyoma and 36 lesions of subserous myomas. Compared with that of pathological results, the accuracy of the combination of transvaginal ultrasound and CEUS for diagnosing the uterine myoma was 100.0%, which was significantly higher than that(89.3%) of transvaginal ultrasound and that(93.8%) of CEUS. The rate of the missed diagnosis of the combination of transvaginal ultrasound and CEUS for the uterine myoma was 0, which was significantly lower than that(10.7%) of transvaginal ultrasound and that(6.3%) of CEUS(all P<0.05). The accuracy of the combination of transvaginal ultrasound and CEUS for diagnosing the type Ⅰof uterine myoma or the type Ⅱ of uterine myoma was 100.0%, which was significantly higher than that(90.3% or 87.5%) of transvaginal ultrasound and that(94.4% or 90.0%) of CEUS. The diagnostic rate of the combination of transvaginal ultrasound and CEUS of the patients for diagnosing their uterine myoma was significantly higher than that of transvaginal ultrasound or CEUS alone(all P<0.05). There was no significant difference in the diagnostic rate for the submucosal and subserous uterine myoma among the three diagnostic methods(P>0.05). The detection rate of the combination of transvaginal ultrasound and CEUS for diagnosing the uterine myoma was significantly higher than that of transvaginal ultrasound or CEUS alone(all P<0.05). There was no significant difference in the detection rate of the submucosal and subserous uterine myoma among the three diagnostic methods(P>0.05). Conclusion: The combination of transvaginal ultrasound and CEUS of the patients for diagnosing their uterine myoma improves the diagnostic efficacy, which can help to determine the location and number of uterine myomas accurately, and has higher detective rate for the subserous uterine myoma. The combination of transvaginal ultrasound and CEUS of the patients provides the evidences for selecting the reasonable treatment plan in clinical practice.
