Ectopic intrauterine device in the bladder causing cystolithiasis: A case report.

Abstract

BACKGROUNDAn intrauterine device (IUD) is a commonly used contraceptive among women in China. It is widely used because it is safe, effective, simple, economic, and reversible. Among the possible complications, an ectopic IUD in the bladder is rare. It occurs insidiously, has a long course, is associated with a high risk for injury, and is difficult to treat.CASE SUMMARYA 44-year-old woman was admitted for repeated episodes of urinary frequency, urgency, and dysuria over three months. Laboratory tests revealed significantly elevated urine leukocytes and bacteria. Urine culture suggested colonization with Enterococcus faecalis. Abdominal computed tomography images suggested an abnormally positioned IUD that was protruding into the bladder. Cystoscopy revealed a metallic foreign body with multiple stones on its surface in the left posterior bladder wall. The foreign body measured approximately 1 cm. Hysteroscopy revealed the arm of a V-type metal IUD embedded in the middle and upper sections of the anterior wall of the cervical canal. The majority of the IUD was located in the uterine cavity. Cystoscopy was performed, and a holmium laser was utilized to break the stones attached to the portion of the IUD in the bladder. The IUD was then removed through hysteroscopy.CONCLUSIONEctopic IUDs in the bladder can be diagnosed with thorough imaging and safely removed through cystoscopy or hysteroscopy.
