What is an Incarcerated Uterus?

An incarcerated uterus does not ascend into the abdominal cavity. Instead, it becomes wedged in the pelvic cavity between the sacrum and the pubis. The increased pressure displaces the cervix and compromises function of the bladder, kidneys and the colon among other organs.

Symptoms of an Incarcerated Uterus

Patients with incarceration usually though not always experience the following symptoms between 12 and 20 weeks of their pregnancy:

Frequent need to urinate
Sense of incomplete bladder emptying
Urinary retention
Constipation
Lower abdominal pain
Vaginal bleeding
Sometimes a woman with an incarcerated uterus will remain asymptomatic until the third trimester or even until labor begins at term.

If an incarcerated uterus is suspected, a manual exam and ultrasound are used to confirm the diagnosis.

Consequences of an Incarcerated Uterus?

Patients with an untreated incarcerated uterus may experience hemorrhage and spontaneous abortion. Fetal loss of up to 33% has been reported in women with uterine incarceration. The earlier the incarceration is detected, the more favorable the prognosis for the fetus.

Less commonly reported complications include intrauterine infection, rectal gangrene and rupture of the bladder or uterus.
