Accidental introduction of a contraceptive vaginal ring into the urinary bladder.

Introduction and hypothesis: 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.
