Migration of an intrauterine device into the bladder: a rare case.

Introduction: Intrauterine device (IUD) application has been used for over 30 years and is a widely accepted contraception method among women because of its low-complication rates. The use of intrauterine devices may cause complications but migration of the IUD into an adjacent organ is rarely encountered.

Case: In the present report, we present a 26-year-old patient to whom IUD had been applied 2 years ago and whose examination performed due to pain and urinary complaints revealed migration of the uterine device into the bladder.

Conclusion: Patients with pelvic pain and chronic irritative urinary symptoms whose vaginal examination and ultrasonography reveal a dislocated IUD should be carefully examined for the migration of the IUD into the bladder. In order to avoid this rare complication, patient should be evaluated physically and ultrasonographically for uterine position, thinness of the uterine wall and inflammatory disease before the insertion. The patient should be evaluated with sonography immediately after insertion and periodically.
