How is uterine prolapse classified?

Patient's question:

No

Doctor's answer:

Hello, according to the degree of prolapse, it can be divided into three degrees:
　　I degree: The uterine body descends, and the cervical os is located between the ischial spines and the vaginal orifice. During vaginal examination, the cervical os is within 4 cm of the vaginal orifice.
　　II degree: Refers to the cervix having prolapsed outside the vaginal orifice, while the uterine body or part of it remains inside the vagina. However, due to the broad scope of inclusion, mild cases may only involve the cervix prolapsing outside the vaginal orifice, while severe cases may result in prolonged cervix, causing the elongated cervix and the entire vaginal wall to prolapse outside the vaginal orifice.
　　II degree uterine prolapse is further divided into mild and severe types.
　　Mild II degree: The cervix and part of the anterior vaginal wall prolapse outside the vaginal orifice.
　　Severe II degree: The cervix, part of the uterine body, and most or all of the anterior vaginal wall prolapse outside the vaginal orifice.
　　III degree: Refers to the entire uterine body and cervix, along with the entire anterior vaginal wall and part of the posterior vaginal wall, all prolapsing outside the vaginal orifice.
