Endoscopic Treatment of Intrauterine Device Migration into the Bladder with Stone Formation

Background: An intrauterine device is commonly used for contraception globally. Although intrauterine device placement is an effective and safe method of contraception, migration into the bladder with stone formation is a rare and serious complication. The management approaches for an intrauterine device embedded in the bladder include endoscopic procedures and open surgical removal. In this study, we report the case of a patient with recurrent urinary tract infection associated with intrauterine device migration and urolithiasis, who successfully underwent endoscopic treatment combined with laser fragmentation. Case Presentation: A 22-year-old woman presented to our hospital with a 1-month history of lower abdominal pain, hematuria, and pain on urination. Transvaginal ultrasound showed a hyperechoic lesion in the bladder. A plain abdominal radiograph showed the presence of a T-shaped intrauterine device with calculus formation in the pelvis. CT revealed a vesical stone fixed to the top of the bladder wall, and there was no vesicovaginal fistula formation. She had undergone intrauterine device insertion several years previously. Cystoscopy confirmed the diagnosis. She underwent endoscopic lithotripsy, and the intrauterine device was extracted from the bladder wall. Repair of the bladder wall and disappearance of symptoms were confirmed. Conclusion: Endoscopic treatment combined with laser fragmentation of stones surrounding a migrated intrauterine device should be considered as a minimally invasive approach, which can be performed safely.
