Objective:

To report a rare case of IUD displacement into the urinary bladder that remained undiagnosed for nine years and to review existing literature on this complication.

Approach:
  • Case Presentation: A 38-year-old woman presented with persistent lower abdominal pain lasting one week. CT and color Doppler ultrasound confirmed IUD migration into the bladder, leading to surgical retrieval.
Key Findings:
  • IUD displacement into the urinary bladder is an exceedingly rare complication.
  • The patient experienced a nine-year diagnostic delay due to atypical symptom presentation.
  • CT imaging was crucial for confirming the diagnosis when ultrasound was inconclusive.
Interpretation:

The case highlights the importance of thorough post-procedural evaluation in patients with new or persistent symptoms following IUD insertion.

Limitations:
  • The study is based on a single case report, limiting generalizability.
  • The literature review may not encompass all relevant cases due to exclusion criteria.
Conclusion:

Timely diagnosis and intervention are critical in cases of IUD displacement, particularly when symptoms persist or evolve.
