Intrauterine Contraceptive Device (IUCD) when placed in the uterine cavity is used for contraception or treatment of intrauterine adhesion, but it has become a cause of unintended bladder stone due to wrongful placement or migration. It may cause blood in urine and painful urination. Pelvic ultrasound and X-ray were used to make the diagnosis of the bladder stone with the embedded IUCD, which was removed by open vesicolithotomy through a Pfannenstiel suprapubic incision. Cases such as this are highly preventable if post procedure and routine annual pelvic ultrasonography are emphasized as standard practice following IUCD insertions.
