Urinary Retention in an Adolescent with a History of Urethral Transection

Hematocolpos is an uncommon but well-described cause of urinary retention in premenarchal females. This is a difficult diagnosis in any circumstance, and this patient's complex history complicated the process. It was the bizarre bedside ultrasound that prompted further work-up than simple urethral catheterization and urologic follow-up, which her urologist had suggested over the phone. This patient's case is unique in the literature.
