Analysis of the Causes of False Positives and False Negatives in Four-dimensional Uterine Fallopian Tube

ABSTRACT Objective: To investigate and analyze the causes of false-positive and false-negative contrast-enhanced ultrasound in four-dimensional uterine fallopian tubes. Methods: 125 patients who were initially diagnosed with tubal infertility in our obstetrics and gynecology clinic from June 2015 to August 2019 were selected. All patients were given X-ray hysterosalpingography (HSG) and four-dimensional uterus contrast-enhanced fallopian tube ultrasonography, recorded the diagnostic effect, adverse reactions, and judging the causes of false positives and false negatives. Results: In the 125 patients, HSG diagnosed 33 cases of unobstructed fallopian tube, 72 cases of unobstructed, and 20 cases of obstruction; 4four-dimensional contrast-enhanced ultrasound showed 33 cases of unobstructed fallopian tube, 74 cases of unobstructed, and 18 cases of blocked. Used the HSG as the gold standard, the accuracy rate of fallopian tube obstruction by four-dimensional contrast-enhanced ultrasound were 93.6 %, Kappa value=0.929 (P<0.05), and there were 8 cases of false positive and false negative occurred. The incidence of adverse reactions such as small vaginal bleeding, contrast agent hypersensitivity, nausea and vomiting, and abdominal pain during four-dimensional contrast-enhanced ultrasound examination were 2.4 %, which were significantly lower than 13.6 % of HSG examination (P<0.05). The univariate analysis results showed that the false positives and false negatives of combined diabetic, parity, age of menarche, pregnancy, and four-dimensional uterine fallopian tube ultrasound contrast were significantly correlated (P<0.05). The results of multivariate logistic regression analysis showed that combined diabetes, parity, and menarche Age were the main cause of false positives and false negatives of four-dimensional uterine fallopian tube ultrasonography (P<0.05). Conclusion: Four-dimensional uterine fallopian tube ultrasound can dynamically observe tubal patency in real time, and there application safety is also good, but there are also false positives and false negatives. Combining diabetes, parity, and menarche age are the main cause of false-positive and false-negative of four-dimensional uterine fallopian tube ultrasonography.
