Early-onset complete spontaneous migration of contraceptive intrauterine device to the bladder in a post C-section patient: A case report.

Spontaneous migration of a contraceptive intrauterine device (IUD) to the bladder is very rare. It usually takes years for the IUD to migrate completely from the uterine cavity to the bladder. We report a case of early-onset complete spontaneous migration of contraceptive IUD to the bladder in a post C-section patient. A 30-year-old woman presented with suprapubic pain and dysuria three weeks prior to hospitalization. She had C-section three months prior and underwent copper IUD insertion two months after the surgery. One week after IUD insertion, radiography showed that the IUD remained in the uterus, but the patient felt suprapubic pain and dysuria. Computed tomography (CT) three weeks after IUD insertions showed IUD migration to the bladder with its tips embedded in the uterine wall. Cystoscopy was performed one week later and the IUD was completely inside the bladder. By then, the IUD was removed completely via forceps with no complication. The exact pathophysiology of spontaneous IUD migration is unknown, but migration always starts with uterine perforation. In our case, uterine perforation was probably caused by immediate traumatic perforation. CT is the preferred radiological examination. IUD removal was performed one month after IUD insertion showing complete migration of the IUD, though CT one week prior suggested that the tips of the IUD remained embedded. In cases of early-onset complete spontaneous migration of contraceptive IUD to the bladder, CT is the preferred radiological examination, and delaying removal procedure may be beneficial.
