Treatment of a late second-trimester incarcerated uterus using ultrasound-guided manual reduction.

Background: Incarcerated gravid uterus diagnosed after 20 weeks of gestation is extremely rare and carries significant morbidity to the fetus and mother.

Case: A 33-year-old woman presented at 21 weeks of gestation with urinary retention. Ultrasonography was performed and a diagnosis of an incarcerated gravid uterus was confirmed using magnetic resonance imaging. Under general anesthesia with ultrasonographic guidance, the incarcerated uterus was successfully released. The patient delivered at 33 weeks by spontaneous vaginal delivery.

Conclusion: Use of ultrasonography for guidance along with general anesthesia during manual reduction may aid the release of a late second-trimester incarcerated uterus.
