Background: Intrauterine Device (IUD) Multiload 375 is a method of contraception widely used worldwide. One of the rare complications is that the IUD punctures the uterus and moves into the bladder. Common manifestations are recurrent urinary tract infections and bladder stones. A long-term and neglected IUD increases the risk of uterine perforation and migration to other organs.
Diagnosis: Clinical history, Cystoscopy, Transvaginal Ultrasound (US) or Computed Tomography helps confirm the diagnosis.
Case Report: We report successful surgical treatment of a 39-year-old woman who neglected to insert a Multiload 375 IUD for 16 years, but still experienced 2 subsequent vaginal deliveries and eventually developed UTI. Bladder stone formation caused by the passage of the Multiload 375 intrauterine device through the bladder.
Conclusions: Urologists should consider bladder foreign bodies as a displaced IUD in women with recurrent lower urinary tract infections or bladder stones, with a history of IUD use. The moving IUD needs to be removed through cystoscopy, laparoscopy, or open surgery. Proper monitoring and education for women’s health before and after IUD insertion helps to detect complications in a timely manner.
