33yo female patient, PARA 4004, with chief complaints: hypogastric pain and dysuria for a long time.

She used a T-shape IUD after having a first child in 2002, but removed the IUD at the third month of the second pregnancy. She had more 2 another children from 2004 to 2008. And she reused IUD since then.

Ultrasound detected an intrauterine T-shape IUD  and a foreign body inside urinary bladder with dirty shadowing.


Cystoscopy detected an adherent stone in urinary bladder (UB).


MDCT revealed 2 T-shape IUDs coexisting, one inside uterus, another perforating the uterus while the transversal tip of this IUD inserted the UB wall and inducing stone formation. The later IUD was a complicated migrating T- shape IUD.


At last, surgery removed the complicated migrating IUD which remained with 3 foeti, and proved that there were 2 IUDs coexisting in a patient, one of those inserted the UB wall and inducing UB stone formation.
