Incarceration of the retroverted gravid uterus: report of four patients managed with uterine reduction.

Incarceration of the retroverted gravid uterus may have an adverse effect on pregnancy. To evaluate these effects, we reviewed obstetric records to identify parturients with the diagnosis of incarceration of the retroverted uterus during the years 1977 to 1987. Four such patients were identified by this retrospective review, for a calculated incidence in our primary population (patients not referred for evaluation who also received prenatal care at only one hospital) of one case per 10,384 live births. The incarceration was successfully reduced in all four patients without surgical intervention, and all had a normal infant of appropriate weight at term.
