Recurrent urinary retention due to imperforate hymen after hymenotomy failure: a rare case report and review of the literature.

Acute urinary retention (AUR) is unusual in children. We report for the first time a case of recurrent urinary retention due to massive hematocolpos resulting from an imperforate hymen in a 14-year-old girl. In case of AUR in adolescent girls, clinicians should keep in mind that imperforate hymen may be a causative factor and this condition may easily be treated surgically, but follow-up is still necessary to ensure that there is no recurrence.
