[Migration of an intra uterine device into the bladder].

The migration of an intra uterine device (IUCD) into the bladder is a rare complication. The authors report a case of IUCD migrated into the bladder. The patient was asymptomatic. Diagnosis was made on abdominal X-ray performed for another reason. It was confirmed by ultrasound and cystoscopy. As the IUCD was only partially intra vesical, it's removal was made by laparoscopy and cystoscopy. The authors then discussed the frequency, the physiopathology, the diagnosis and the treatment with arguments from the literature.
