Uterine Incarceration: Rare Cause of Urinary Retention in Healthy Pregnant Patients.

Gravid uterine incarceration (GUI) is a condition that is well discussed in literature; however, there are few acute diagnoses in the emergency department (ED). We present a case series where three multiparous females presented to the ED with non-specific urinary symptoms. On bedside ultrasound, each patient was noted to have a retroverted uterus and inferior bladder entrapment under the sacral promontory. GUI is a rare condition that can lead to uremia, sepsis, peritonitis, and ultimately maternal death. Emergency physicians should include GUI in their differential diagnosis in this patient population and use bedside ultrasound as an adjunct to diagnosis.
