Comparing the results of operative hysteroscopy in patients with active bleeding with and without uterine evacuation before the procedure

The study was designed to asses whether removing clots and contents of the uterine cavity before hysteroscopy would lead to better procedure outcomes(bleeding, media use, procedure duration, and hospital stay duration)
Bleeding Categories are created based on the surgeon and operating nurse's estimation on the bleeding amount.

本研究旨在评估在宫腔镜检查前清除子宫腔内的血栓及其内容物是否能够提高手术操作的结局（包括出血量、药物使用、手术持续时间及住院时间）。出血类别系基于手术医师及手术护士对出血量的预估而创建。
