Background
Intrauterine devices are safe, affordable, convenient, and the most common form of contraception used by females of childbearing age. A rare complication of intrauterine devices is migration to nearby structures, rarely the urinary bladder, leading to bladder stone formation.
Case Presentation
A 34-year-old female patient presented due to repeated urinary tract infections and flank pain associated with lower urinary tract symptoms, including dysuria, frequency, and gross hematuria. Subsequent laboratory tests revealed a past medical history of iron-deficiency anemia. Urinalysis revealed hematuria and pyuria, and the urine culture confirmed colonization of Escherichia coli. Computed tomography revealed an irregularly shaped 5.5 cm hyperdense, suspicious-looking stone in the urinary bladder. Open cystolithotomy was done to extract the stone, which was later incidentally revealed to be a stone formed around a migrated intrauterine device.
Conclusions
The case highlights the rare potential of intrauterine devices to migrate to the urinary bladder and lead to stone formation, which, in this case, was discovered nine years after intrauterine device insertion. The perforation was due to delayed inflammatory migration from the uterine cavity to the urinary bladder lumen. This case emphasizes the need to educate the patient after intrauterine device placement and increase patient and physician awareness to recognize the warning signs of intrauterine device migration.
