目的 :通过对 31例不孕症妇女 (6 0侧输卵管 )行改进的核素输卵管造影 (RNHS) ,评价该方法对判断不孕症妇女输卵管通畅程度的价值。资料与方法 :一次性导尿管直接插入宫腔 ,37MBq99mTcO4 经导管注入后动态采集 ,同时缓慢加压注入生理盐水 ,然后行静态采集。其中 10例 (2 0侧输卵管 )行X线子宫输卵管碘油造影进行对照。结果 :RNSH示输卵管通 41例 ,阻塞 19侧。以子宫输卵管碘油造影为诊断标准 ,RNHS灵敏度为 85 .7% ,特异性为 84.6 %。结论 :RNHS有效 ,安全 ,无创 ,值得在临床推广应用。
OBJECTIVE: To evaluate the value of this method in determining the degree of fallopian tube patency in 31 infertile women (60 tubal) with improved tubal tubal imaging (RNHS). Materials and Methods: A one-time catheter was inserted directly into the uterine cavity. 37MBq99mTcO4 was collected dynamically after catheterization, meanwhile, it was slowly pressurized and infused into normal saline. Of which 10 cases (20 side fallopian tubes) underwent X-ray hysterosalpingography contrast. Results: RNSH showed tubal pass in 41 cases, blocking 19 sides. Uterine tubal iodine oil as the diagnostic criteria, RNHS sensitivity was 85.7%, specificity was 84.6%. Conclusion: RNHS is effective, safe and noninvasive and worthy of clinical application.
