JF Journal of Accident & Emergency Medicine JO Arch Emerg Med FD BMJ Publishing Group Ltd and the British Association for Accident & Emergency Medicine SP 232 OP 233 DO 10.1136/emj.16.3.232 VO 16 IS 3 A1 D J Hall YR 1999 UL http://emj.bmj.com/content/16/3/232.abstract AB A 15 year old girl presented to the accident and emergency (A&E) department with a 24 hour history of lower abdominal pain, and was found to have acute urinary retention. She was discovered to have an imperforate hymen with associated haematocolpos and haematometrium. This is rare and is hence a very unusual presentation to the A&E department. Patients presenting with retention of urine should be carefully assessed for the cause.
