Retroverted impacted gravid uterus with acute urinary retention: report of two cases and a review of the literature.

Two cases of acute urinary retention in association with a retroverted impacted gravid uterus are described. Manual replacement of the uterus into an anterior position resolved the urinary retention in both cases. A review of the literature for retroverted impacted gravid uterus and related disorders is given. Successful treatment of retroverted impacted gravid uterus can usually be performed by initial bladder catheterization followed by manual replacement of the uterus, or by chronic bladder drainage until the uterus ascends out of the pelvis.
