目的 探讨经阴道三维子宫输卵管超声造影(3D-HyCOSy)在不孕症中的作用。方法 将不孕症患者66例按照数字表 法随机分为3D-HyCOSy组与X线子宫输卵管造影（HSG）组，每组各33例，并与腹腔镜检查结果进行自身对比分 析。结果 3D-HyCOSy组33例66条，输卵管通畅53条占80.30%(53/66)，通而不畅9条占13.64%（9/66），阻塞4条 占6.06%（8/66）。HSG组33例66条输卵管通畅37条占56.06%(37/66)，通而不畅14条占21.21%（14/66），阻塞15 条占22.73%（15/66）。经腹腔镜检查提示3D-HyCOSy组符合率为(80.41±2.4)%，而HSG组为(59.13±5.76)%(P ＜0.05)。结论 3D-HyCOSy诊断不孕症是一种简便、有效、无创、安全、准确、可重复、无辐射又不影响怀孕等优 点，对子宫宫腔病变和输卵管的通畅性的诊断及鉴别明显优于传统的HSG。

Objective To study the transvaginal three-dimensional uterus fallopian tube ultrasonic angiography (3d-HyCOSy) role in infertility. Methods 66 cases of infertility patients according to the digital table method were randomly divided into 3 d - HyCOSy group and X-ray uterus oviduct imaging (HSG) group, 33 cases in each group, and its comparison with laparoscopy results analysis. Results 3 d-HyCOSy group 33 cases 66, tubal patency article 53 accounted for 80.30% (53/66), general and poor article 9 was 13.64% (9/66), blocking the four accounts for 6.06% (8/66). HSG group of 33 cases of tubal patency of article 66 of the article 37 accounted for 56.06% (37/66), flux and 14 accounted for 21.21% (14/66), blocking the article 15. 22.73% (15/66). After laparoscopic examination clew 3 d - HyCOSy groups were (80.41+2.4) %, (59.13+5.76) % for the HSG ones (P<0.05). Conclusion 3 d-HyCOSy diagnosis of infertility is a simple, effective and noninvasive, safe, accurate and repeatable, and the advantages of no radiation and does not affect the pregnancy, the uterine cavity lesions of uterus and fallopian tube patency of diagnosis and differential is superior to the traditional HSG.
