Computed tomography scans (CT) revealed that one arm of the IUD had migrated into the bladder, causing bladder stones. The patient underwent transurethral bladder lithotripsy and stone removal, laparoscopic bladder repair, and hysteroscopic removal of the IUD. The IUD was completely removed, and the bladder stones were successfully treated. The patient made a good postoperative recovery.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Regular follow-up examinations are required following the insertion of an IUD, with ultrasound being the preferred method of follow-up. If recurrent urinary symptoms occur, the possibility of IUD migration into the bladder should be ruled out.
