Bladder Stone Secondary to Migration of an Intrauterine Device: A Case Report

ABSTRACT Intravesical migration of intrauterine devices (IUDs) is an uncommon complication that may lead to recurrent urinary tract infections, lower urinary tract symptoms, and bladder stone formation. Diagnosis requires high clinical suspicion and confirmation through imaging and cystoscopy. We present the case of a 33‐year‐old hypertensive woman with a history of two cesarean deliveries for preeclampsia who underwent IUD placement in 2016. She subsequently developed recurrent urinary tract infections. In 2024, hysteroscopic removal was attempted unsuccessfully. Computed tomography revealed a calcified “T‐shaped” image in the posterior right bladder wall. Open cystolithotomy was performed, achieving complete removal without complications, and the patient had a favorable postoperative course. Bladder migration of IUDs is rare and may occur years after insertion. Clinical presentation is often nonspecific, which can delay diagnosis. Imaging, including CT scan, and cystoscopy are essential for localization and surgical planning. Open cystolithotomy is a safe and effective approach in cases with large calculi. This case highlights the importance of considering intravesical IUD migration in women with persistent urinary tract symptoms and absence of the device in the uterine cavity. Early diagnosis and appropriate surgical management allow safe resolution and prevent major complications.
