To study the diagnostic value of transvaginal color Doppler ultrasound on pelvic tuberculosis. Methods 70 patients with pelvic tuberculosis who were treated in the hospital from January 2016 to January 2019 were selected as the research subjects. All the study subjects underwent transvaginal color Doppler ultrasound examination to observe the two-dimensional sonographic characteristics of pelvic tuberculosis. Contrast-enhanced ultrasound was combined to classify the blood flow characteristics of pelvic tuberculosis and observe the ultrasound characteristics of patients with pelvic tuberculosis. Results The coincidence rate of conventional color Doppler ultrasound was 80.00% in diagnosing pelvic tuberculosis and the coincidence rate of contrast-enhanced ultrasound diagnosis was 72.86%, and the diagnostic accuracy rate of contrast-enhanced ultrasound was higher than that of conventional color Doppler ultrasound, and the accuracy rate of transvaginal ultrasound was high in diagnosing tubal ovarian tuberculosis and tubal tuberculosis. Conventional ultrasound showed that the images of patients with pelvic tuberculosis were dominated by pelvic masses, with grade I-II blood flow signals around and inside the lesions, the maximum lesion diameter of (46. 21±16. 20) mm, irregular shape and unclear boundary. Contrast-enhanced ultrasound showed that the lesions were mainly cystic, with mixed enhanced echo and uneven high enhancement of fallopian tubes. Conclusion Compared with conventional color Doppler ultrasound, contrast-enhanced ultrasound has a higher accuracy in the diagnosis of tubal ovarian tuberculosis and tubal tuberculosis. It can clearly show the blood perfusion, surrounding tissue and echo of the focus, and contrast-enhanced ultrasound has a higher accuracy in the diagnosis of pelvic tuberculosis
