Methods: A retrospective analysis of 175 cases of infertility patients in our hospital from January 2013 to September 2017. Ultrasound examination using Voluson E8 four-dimensional colour Doppler ultrasound diagnostic instrument. Step one, routine two-dimensional ultrasound examination of the uterus and bilateral ovaries. Step two, start the three-dimensional measurement program using OmniView mode, select the Line, Curve, Trace or Polyline method for the uterus in different positions, and sample The line is adjusted to the central position of the endocardium and parallel to the line of the endocardium. Step three, four-dimensional contrast-enhanced ultrasound examination. Results: Among the 175 cases, 8 cases had intrauterine adhesions, 12 cases had uterine polyps, 1 case had single uterine horn, and 1 case had incomplete septate uterus. Four-dimensional contrast-enhanced ultrasonography revealed 46 cases of tubal obstruction. Using pathological results as the gold standard, the sensitivity, specificity, positive response rate, and negative response rate of uterine polyps diagnosed by OmniView were 91.67% (11/12), 18.75% (3/16), 4.88, and 0.1 respectively. The sensitivity, specificity, positive response rate, and negative response rate of OmniView technique for diagnosing intrauterine adhesions were 87.50% (7/8), 25.00% (3/20), 3.5, and 0.15, respectively. The total coincidence rate of laparoscopic dye-fluid assay for judging tubal patency was 95.83% (46/48). The two methods had higher consistency (Kappa=0.804, P<0.001). Conclusions: The combination of transvaginal three-dimensional ultrasound-free anatomy and hysterosalpingogram four-dimensional contrast-enhanced ultrasound can make a comprehensive assessment of the uterine cavity fallopian tube in a systematic examination, which is helpful for the diagnosis of clinical infertility.
