Tubal Obstruction Caused by Ureaplasma urealyticum and Chlamydia trachomatis Infection

Objective To investigate the relationship between Ureaplasma urealyticum (UU) and Chlamydia trachomatis (CT) infections and tubal obstruction. Methods 300 cases of infertilie women and 300 cases of healthy women were examined for leucorrhea,UU,CT and hysterosalpingography (HSG). Results 248 cases of non-gonococus infections were found in the infertility group, with a positive rate of 82.66% (248/300)(CT, UU and CT+UU positive rates were 28.33% (85/300), 32.67% (95/300), and 22.67% (68/300),respectively). 15 cases of non-gonococus infections were fond in the control group, with a positive rate of 5% (15/300)(CT, UU and CT+UU positive rates were 2.33% (7/300), 2.0% (6/300), 1.0% (3/300), respectively). There was a significant different between the two groups (P0.001). HSG results showed that the rates of incomplete tubal obstruction of the infertile group and the control group were 42.67% (128/300) and 5.67% (17/300),respectively, while the rates of complete tubal obstruction were 23.33% (70/300) and 3.33% (10/300), respectively. The difference between these two groups was also significant, P0.001. Conclusion The infection of UU and CT is the major pathogenic factor of tubal obstruction. It is necessary to detect UU and CT before infertile examination or uterine operation.
