A case of third trimester uterine prolapse resulting in vaginal delivery by placement of an intravaginal balloon

Pregnancies complicated by uterine prolapse are rare, occurring in 1 in 10 000 to 15 000 deliveries. We report a case of uterine prolapse at 36 weeks of gestation that resulted in vaginal delivery by placement of a colpeurynter (intravaginal balloon). The patient was a 33-year-old pregnant woman with a history of uterine prolapse during her previous pregnancy. At 36 weeks and 4 days of gestation, she presented to her previous physician with uterine prolapse and genital bleeding. Due to severe edema of the uterine cervix, she was referred to our hospital for specialized care. The cervix was manually repositioned into the vagina and the patient was discharged. Concerned about recurrence of uterine prolapse and cervical incarceration at delivery, labor was induced at 39 weeks and 5 days of gestation by oral prostaglandin preparations with concurrent placement of a colpeurynter, resulting in vaginal delivery. Colpeurynter placement is a simple procedure and may be useful in preventing uterine prolapse at delivery.
