Iatrogenic uterine diverticulum in pregnancy after robotic-assisted myomectomy

Uterine diverticula are rare outpouchings of the uterus associated with abnormal uterine bleeding, pelvic pain, dysmenorrhea, and adverse obstetric events. At the time of cesarean delivery at 36 5/7 weeks' gestation during the patient's first pregnancy and 36 6/7 weeks during the second pregnancy, a fundal iatrogenic uterine diverticulum at the site of a prior robotic-assisted myomectomy was noted. The outpouching communicated with the endometrial cavity and was extremely attenuated, palpably 2 to 3mmthick. Further research is needed to determine the incidence of iatrogenic uterine diverticulum after robotic myomectomy and whether these malformations increase the risk of adverse obstetric outcomes.
