[Incarcerated retroverted gravid uterus successfully repositioned with colonoscopy].

A 36-year-old woman presented with a urinary retention at gestational age 15 weeks + 5 days. After two days with intermittent catheterisation a magnetic resonance imaging confirmed the diagnosis. Under spinal anaesthesia with ultrasonographic guidance, manual reposition of the incarcerated uterus was first tried, but unsuccessfully. The patient was rolled to her left side, and a diagnostic colonoscopy was performed. A post-procedure ultrasonography and a vaginal examination revealed that the uterus was repositioned. The patient was released with no following symptoms. Follow-up at the gestational age 19 weeks + 5 days showed normal conditions.
