What is a uterine rupture?

Muscle tears: The uterus is a muscle that can rupture, or tear. Most commonly, uterine rupture occurs at the site of scar formation. For example, after a woman has a cesarean section (in which the uterus is opened and stitched back together), a scar will form. This scar in the uterus could tear apart during a subsequent labor, causing uterine rupture.

Bad news: Uterine rupture is usually associated with pregnancy and although uncommon, can lead to hemorrhage & death of both mom & infant. Your doc can tell you if you have any risks & how to keep you safe in pregnancy. Consider it a risk with any prior uterine surgery (including certain types of c-sections, fibroid surgery), long labors, or anything that overdistends the uterus.

Bad complication: During labor when uterine muscle contract it can rupture because the force is very strong. Chances of rupture are higher after a cesarean because the scar tissue is not as strong as normal tissue.
