Which degree of uterine prolapse is characterized by the cervix reaching the introitus?

Second degree uterine prolapse is characterized by the cervix reaching the introitus, meaning that the cervix is visible at the vaginal opening while the uterus is still within the vaginal canal. In this stage, the uterine support structures have weakened sufficiently for the cervix to descend but not completely outside the body.

This level of prolapse indicates a moderate degree of pelvic floor dysfunction, as the support structures (such as the uterosacral and cardinal ligaments) have allowed the cervix to drop lower than its usual position without completely exiting the vaginal canal. Understanding the distinctions among the degrees of uterine prolapse is vital for assessing the severity of the condition and determining the most appropriate management options, which may differ based on how far the uterus and cervix have descended.

In contrast, first degree prolapse involves a prolapse of the uterus without any descent of the cervix beyond the vaginal wall, third degree involves the cervix and body of the uterus protruding outside the vaginal opening, and fourth degree is complete eversion of the vagina and uterus, often referred to as procidentia.
