Background: Water under high pressure can produce vaginal injury. Previous reports suggest that postmenarcheal maturation and the presence of a vaginal foreign body contributed to water slide injuries in women.
Methods: A case of a vaginal injury from a water slide in a premenarcheal patient is presented. A literature review of water-related vaginal injuries in adults and children compares the mechanism of injury with that previously reported.
Results: The patient underwent operative repair of her injury.
Conclusions: Vaginal injury in premenarcheal patients may result from a water slide. The emergency physician must be aware of this potential injury mechanism and the need for complete examination under anesthesia when vaginal bleeding is present.
