title: Accidental introduction of a contraceptive vaginal ring into the urinary bladder.
abstract: OBJECTIVE
  A case of inadvertent self-introduction into the urethra of a folded contraceptive vaginal ring (NuvaRing) in a 22-year-old woman is reported.
  
  
  METHODS
  The patient presented with lower urinary tract symptoms, including dysuria, urgency, and terminal hematuria, that appeared a few minutes after insertion of the device.
  
  
  RESULTS
  The diagnosis was made by abdominal echography. The abdominal pelvic computed tomography scan confirmed the intravesical presence of the unfolded ring.
  
  
  CONCLUSIONS
  Vaginal contraceptive rings should be added to the list of potential intravesical foreign bodies causing lower urinary tract symptoms.
