Uterine diverticulum is often a symptom of post-cesarean section, and is clinically manifested by incomplete menstruation and prolonged menstruation. In clinical practice, which procedure is better depends on the specific situation of the diverticulum. If the thickness of the diverticulum is greater than 4mm, hysteroscopy can be performed to remove the excess diverticulum, which will improve the dysmenorrhea caused by the diverticulum. In addition, if you want to continue the pregnancy, it is recommended that if the thickness of the diverticulum is less than 4mm, you should do local repair surgery before considering pregnancy, so as to avoid the increase in the size of the uterus after pregnancy, making the diverticulum thinner and thinner, which may lead to uterine rupture.
