Uterine ectropion is a rare clinical condition that can be caused by a woman’s uterus turning out during labor and delivery. Uterine ectropion is a serious gynecological condition that occurs when the lining of the uterus flips from inside the uterus to outside the uterus, usually due to an emergency delivery or improper handling during labor. If uterine ectropion occurs, it may cause hemorrhage and shock, and once it occurs, it will cause great harm to the woman, so when a woman has uterine ectropion, she needs to undergo immediate surgical treatment. Uterine ectropion may be clinically due to excessive contraction of the uterus in PMS women, which causes the uterus to turn out beyond the vagina due to excessive pulling.
