目的研究解脲支原体 (UU)和沙眼衣原体 (CT)感染对孕囊枯萎的影响。方法应用支原体培养和衣原体抗原免疫快速法对 10 2例囊枯萎组 (观察组 )和 86例早孕人工流产 (对照组 )宫颈分泌物进行UU和CT的检测。结果观察组宫颈分泌物UU和CT阳性检出率分别为 36 .2 %和 2 0 .6 % ,均明显高于对照组(P <0 .0 1)。观察组UU和CT复合感染率为19 .6 % ,也较对照组明显升高 (P <0 .0 1)。术后随访 2年 ,UU和CT阳性组其输卵管妊娠的发生率升高。结论UU和CT感染与孕囊枯萎密切相关。  Objective  To study the effects of UU and CT on gestational sac wilt.  Methods U UU and CT examination of cervical secretions in 102 cases of vesicular wilting (observation group) and 86 cases of abortion in early pregnancy (control group) were performed by using mycoplasma culture and Chlamydia antigen immunization.  Results  The positive rate of UU and CT in cervix secretion in the observation group was 36.2% and 20.6% respectively, which were significantly higher than those in the control group (P <0.01). The combined infection rate of UU and CT in the observation group was 19.6%, which was also significantly higher than that in the control group (P <0.01). After 2 years of follow-up, the incidence of tubal pregnancy in UU and CT positive group increased.  Conclusion UU and CT infection is closely related to gestational sac wilt.
