Uterovesical fistula and bladder stones following bladder penetration by a perforating intrauterine contraceptive device

Intrauterine Contraceptive Device Migrated in the Urinary Tract: Case Report and Extensive Literature Review

The migration or translocation of an intrauterine device (IUD) in the urinary tract is a rare event. Here, we present the case of a 55-year-old woman who accidentally discovered the ectopic presence of an IUD following a radiological examination for pelvic pain caused by a lumbar discopathy. Over the years, the patient had several IUDs inserted without being able to specify which one had migrated. The removal of the IUD was performed laparoscopically with the minimum resection of the bladder wall and the subsequent cystorrhaphy. The evolution of the patient was favorable. To better analyze these events, we conducted an all-time extensive electronic search of the PubMed database and identified 94 eligible articles, with a total of 115 cases. The literature analysis on the IUD migrations shows either the simultaneous existence of the second IUD or of a maximum number of up to two IUD insertions during the life of patients. Thus, in the presented case, we identified five IUD insertions over time, which explained the chronic inflammatory process by forming an important mass of adherents that included the urinary bladder, uterus, omentum, sigmoid colon, and abdominal wall. Therapeutic management must be adapted to each case depending on the intra/extravesical location of the migrated IUD evaluated by imaging.

[Intrauterine device migration to the bladder: four case reports]

The intrauterine device has been commonly used in our population for many years as contraceptive method. One of the complications is the device migration out of the uterus. One of the most uncommon fait of this migration is the bladder, with few reports on the literature. In this work, four cases are reported with their clinical presentation, study and treatment.
