Arch Gynecol Obstet (2009) 279:739–742 DOI 10.1007/s00404-008-0792-3 123 CASE REPORT Migration of an intrauterine device into the bladder: a rare case Umur Yensel · Incim Bezircioglu · Ali Yavuzcan · Ali Baloglu · Burcu Cetinkaya Received: 7 July 2008 / Accepted: 28 August 2008 / Published online: 17 September 2008  Springer-Verlag 2008 Abstract Introduction Intrauterine device (IUD) application has been used for over 30 years and is a widely accepted contraception method among women because of its low- complication rates. The use of intrauterine devices may cause complications but migration of the IUD into an adjacent organ is rarely encountered. Case In the present report, we present a 26-year-old patient to whom IUD had been applied 2 years ago and whose examination performed due to pain and urinary com- plaints revealed migration of the uterine device into the bladder. Conclusion Patients with pelvic pain and chronic irrita- tive urinary symptoms whose vaginal examination and ultrasonography reveal a dislocated IUD should be carefully examined for the migration of the IUD into the bladder. In order to avoid this rare complication, patient should be evaluated physically and ultrasonographically for uterine position, thinness of the uterine wall and inXamma- tory disease before the insertion. The patient should be evaluated with sonography immediately after insertion and periodically. Keywords Bladder · Intrauterine device · Migration Introduction Intrauterine device (IUD) application has been used for over 30 years and is a widely accepted contraception method among women because of its low-complication rates [1]. The use of intrauterine devices may cause compli- cations, such as pelvic abscess, uterine rupture and septic abortion. The incidence of uterine perforation is 1–3 in 1,000 applications [2]. However, the migration of the IUD into an adjacent organ is rarely encountered. In the present report, we present a 26-year-old patient to whom IUD had been applied 2 years ago and whose exami- nation performed due to pain and urinary complaints revealed migration of the uterine device into the bladder. The case A 26-year-old patient to whom IUD had been applied 2 years ago was admitted to our hospital with complaints of pelvic pain and urinary system infections. The vaginal examination revealed that the IUD was dislocated. Urinaly- sis and all other laboratory Wndings including a complete blood count and blood biochemistry proWle were within normal levels. There were no data to support tendency of urolithiasis. Pelvic ultrasonography revealed hyperecoge- nity in the bladder wall, which might be consistent with IUD. Intrauterine device was detected in the pelvis via direct pelvic radiography examinations. Pelvic computed U. Yensel · I. Bezircioglu · A. Yavuzcan (&) · A. Baloglu · B.
