The current grading of uterine prolapse commonly used in China can be divided into mild, moderate, and severe. The grading is based on the position and severity of the prolapse. Generally, mild indicates that the prolapse of the uterus has not exceeded the external orifice of the vagina. Moderate indicates that part of the uterus has prolapsed beyond the vaginal orifice, and the most severe suggests that the uterus has completely prolapsed to the external orifice of the vagina. Therefore, a gynecological examination is needed in the clinic for assessment.
