Abstract：Objective: To study the application value of transrectal ultrasonography(TRS) in diagnosing gynecological diseases and compare TRS technique with transabdominal ultrasonography(TAS) and transvaginal ultrasonography(TVS) technique. Methods: Eighty-seven gynecological patients without sex life history were selected randomly. They received TAS exam and following TRS exam with transvaginal intracavitary probe. Fifty-four gynecological patients were selected to receive TVS exam only. We compared TRS with TAS and TVS to explore the differences of visualization. Diagnostic accordance rate of TRS were compared with that of TAS in 87 patients by follow-up visiting. Results: The detailed visualizing ability in near field (uterus/ovary-center) of TRS was better than TAS significantly(P<0.01). For female patients without sex life history, total diagnostic accordance rate of TRS was higher than that of TAS significantly(88.14% vs. 42.37%, P<0.001). There were no significant differences of outline and detailed visualizing abilities between TRS and TVS(P>0.05). TRS and TVS had similar effects in gynecological detailed visualizing abilities. Conclusion: TRS, which can be taken as a selection of ultrasonography technique in diagnosing gynecological diseases, has outstanding detailed visualizing abilities for uterus and ovaries. It is more appropriate for the gynecological patients without sex life history and need detailed visualizing data.
