目的 探讨分析经阴道三维超声输卵管造影技术在不孕症诊断方面的应用价值。方法 本研究选取2016年1月至2016 年12月在我院进检查的50例不孕症患者作为研究对象，根据数字表法随机分为两组，25例对照组患者采用二维子宫 输卵管超声造影技术检查，25例观察组患者均采用经阴道三维超声输卵管造影技术进行检查，观察其检查结果，并 将其检查结果与手术病理检查结果进行对比。结果 观察组检查的临床符合率为(96.00%)，对照组检查的临床符合 率为(68.00%)，结果在统计学上有意义(P<0.05)；观察组患者的输卵管通畅、输卵管通而不畅、输卵管堵塞的概率 分别为(32.00%)、(28.00%)、(36.00%)和对照组(32.00%)、(32.00%)、(36.00%)无显著差异(P＞0.05)。结论 阴道 三维超声输卵管造影技术在不孕症诊断方面具有显著的临床意义，可以降低漏诊率，提高患者的诊断率，在临床上 值得推广应用。

Objective To investigate the application value of transvaginal three dimensional ultrasonic salpingography in the diagnosis of infertility. Methods 50 cases with infertility in our hospital from January 2016 to December 2016 were selected as study objects, they were randomly divided into two groups according to number table method, 25 cases in the control group were given two dimension HSUG inspection, 25 cases in the observation group was given transvaginal three dimensional ultrasonic salpingography inspection, observe the results of inspection, compare the inspection results with operation pathological results. Results Clinical coincidence rate of the observation group and the control group were 96.00%, 68.00%, the difference was statistic significant (P<0.05), the probability of tubal patency, tubal partially obstructed, tubal obstruction of the observation group and the control group were 32.00%, 28.00%, 36.00% and 32.00%, 32.00%, 36.00% respectively, the difference was not statistic significant (P>0.05). Conclusion The transvaginal three dimensional ultrasonic salpingography has significant clinical value in the diagnosis of infertility, it can lower rate of missed diagnosis, improve diagnostic rate of patients, it is worthy of popularization and application.
