What indicates a third-degree uterine prolapse?

A third-degree uterine prolapse is characterized by the cervix protruding outside the vagina. This stage of prolapse is severe and indicates significant descent of the uterus within the vaginal canal. In third-degree prolapse, the support structures of the pelvic floor have weakened to such an extent that the uterus descends reflexively, leading to the cervix being visible outside of the vaginal opening. This real presentation indicates the need for medical attention, as it can result in various complications and discomfort for the individual.

In contrast, the other options do not accurately represent the characteristics of a third-degree uterine prolapse. For instance, vaginal shortening is typically associated with pelvic floor disorders but does not directly mean that the uterine prolapse has reached a third-degree severity. Similarly, having the cervix at the introitus represents a second-degree uterine prolapse, where the cervix is still within the vaginal opening but is lower than its normal position. Lastly, the absence of symptoms would indicate a lesser degree of prolapse or a completely different issue unrelated to any prolapse severity.
