Transvaginal contraception--avoid the bladder.

We report two cases of female contraceptive methods, resulting in urological presentation, with bladder foreign bodies. History, mode of diagnosis and surgical extraction technique differed in both patients. The first, where a thermometer was lost intravesically whilst measuring an internal temperature, presented immediately. A plain abdominal X-ray confirmed the position of the foreign body. Extraction was performed cystoscopically with the thermometer intact. A second patient, with recurrent urinary tract infections, was found to have an intrauterine contraceptive device (IUCD) in her bladder on ultrasound. Attempts to remove it endoscopically failed, and an, open procedure was required to free the IUCD from the bladder sidewall.
