【摘要】 目的用核素输卵管显像(RNHS)研究输卵管功能正常及异常判断标准,分析原发性和继发性不孕症患者输卵管功能受损程度差异。方法对29例正常对照及126例怀疑输卵管原因的不孕症女性患者,进行改良的RNHS。结果正常对照组通过子宫腔小剂量分次注入显像剂动态观察,卵巢部位显影的时间为(4．0±2．7)s;宫腔内潴留液较多者,卵巢部位显影时间延迟为(18．0±1．2)s。结合加压注射显像剂第2次动态显像对试验组126例252条输卵管研究分析,将输卵管功能受损情况分为6类。而对X线子宫输卵管碘油造影(HSG)显示输卵管机械性通畅的不孕症患者,RNHS结果显示输卵管功能受损的阳性率为70．5%。原发性不孕症患者输卵管功能轻度受损20．3%,重度受损11．9%;继发性不孕症患者输卵管功能轻度受损14．9%,重度受损17．9%。结论改良的RNHS对输卵管功能受损程度及通畅性的判断具有价值。更多还原

【Abstract】 Objective To study the criteria of normal and abnormal oviduct function and the differ- ence of oviduct function between the primary and secondary infertile patients.Methods Twenty-nine cases of normal controls and 126 infertile women were imaged by improved radionuclide hysterosalpingography （RNHS）.Results In the normal control group with small dose fractional injection of ⁹⁹Tc^m-macroaggregat- ed albumin（MAA）into cervical canal,the appearance time of radioactivity in ovarian tube by dynamic im- aging was（4.0±2.7）s.When there was much more liquid retained in uterus,the ovarian appearance time delayed to（18.0±1.2）s.Combined the injection under pressure and second dynamic imaging in all 252 ovarian tubes of 126 cases,the damaged fallopian tubes could be divided into six patterns.Among all of the infertile women whose fallopian tubes showed mechanical patency by the X-ray hysterosalpingography （HSG）,their positivity of damaged fallopian tube fuctian reached 70.5% by RNHS.Besides,the mild and severe functional abnormality of fallopian tube in patients of primary and secondary infertility were 20.3% and 11.9% versus 14.9% and 17.9% respectively.Conclusion Modified RNHS has important diagnostic value for judgment of the damage magnitude and patency of fallopian tube in infertile women.更多还原
