Clinical manifestations of UU, CT, MG, and NG infections. A The most common clinical manifestations in patients with UU, CT, MG, and NG infections were vaginitis, cervicitis, urethritis and annexitis. In addition, the proportion of infertility patients and patients with adverse pregnancy history was relatively high. About 30 ~ 40% of patients had no clinical symptoms. B Leucorrhea analysis was performed in 209 UU positive patients. Only 34.93% of UU positive patients had vaginal inflammation, of which 15.79% were bacterial vaginitis, 11.48% were fungal vaginitis, 0.96% were trichomonas vaginitis and 6.70% for other vaginal inflammation (WBC > 15/HPF). C Of all 873 UU positive cases followed, we observed 10 cases of premature delivery, 2 cases of low birth weight, and 4 cases of neonatal pneumonia associated with maternal UU infection. These results suggest that not all patients with UU infection have significant clinical symptoms. Therefore, screening for urogenital infections in pre-pregnant women without any clinical symptoms is still necessary to avoid adverse pregnancy outcomes
