核素输卵管显像诊断不孕症的价值

The Value of Radionuclide Hysterosalpingography(RNHS) in Infertile Women

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。

Purpose:The determination of fallopian tubal patency is critical in in diagnosing femal mbertility. This study evaluated the efficacy of modified RNHS in the diagnosis. Materials and Methods: Thirty-one infertile women with 60 fallopian tubes (2 tubes had been excised before). Thirty-seven MBq(1mCi) 99m TcO 4 was injected directly into cervical canal using a catheter attached to the syringe and then 5～10ml of 0.9% saline were injected slowly with certain pressure. Dynamic acquisition as performed immediately after administration of the tracer. Result: 41 tubes were found patent and 19 obstructed by RNHS. The sensitivity was 85.7%, and specificity 84.6%, as compared with the contrast hysterosalpingography. Two cases became pregnant after RNHS. Conclusions: RNHS is an efficient method in deterninating of foollopian tubal potency, being less invasive, easier to perform, giving lower does of raidation to infertile women than contrast hysterosalpingography.
