Introduction: The overall specific incidence of an imperforate hymen is unknown, but is<br />

considered a rare event. Rarer still is urinary retention secondary to an imperforate hymen that<br />

leads to hydronephrosis. The hypothesized cause of urinary retention is secondary to the retained<br />

menstrual products in the vagina that causes compression of the posterior bladder wall and urethra<br />

into an angulated position thereby preventing urination.<br />

Case Description: An afebrile, thirteen-year-old Caucasian female presented to the ED with a<br />

history of anuria for twelve hours and severe abdominal discomfort. The patient denied sexual<br />

activity or the onset of menses but admitted to an intermittent cramping abdominal pain for several<br />

months duration. Physical examination revealed a tanner III female and was within normal limits<br />

except for a twenty millimeter mass palpated on abdominal exam to the left of and above the<br />

umbilicus and a bulging, lemon-sized, mucosa-covered mass protruding from the introitus.<br />

Urinary catheterization revealed five hundred cc of clear urine resulting in a decrease in the size of<br />

the abdominal mass. An abdominal ultrasound revealed hematometros-hematocolpos and mild<br />

bilateral Hydronephrosis. Surgical incision of the hymen allowed for the drainage of one liter of<br />

thick, brown retained menstrual blood. A Urinalysis and urine culture was negative for<br />

abnormality or infection.<br />

Discussion: Urinary retention secondary to multiple factors such as constipation, urinary tract<br />

infection, pelvic disorders, trauma, psychosomatic causes, and posterior urethral valves (in males)<br />

are seen in children. However, this case stresses the importance of a complete history and physical<br />

examination during annual examinations, in addition to a review of systems on routine evaluation<br />

of patients such that possible diagnosis can be made. Thus an imperforate hymen may be<br />

diagnosed prior to the secondary presentation of acute urinary retention.<br />
