Perforation of the uterus is rare but potentially fatal. During puerperium
when the uterus is small and its wall is thin, the risk of perforation incr
eases. We report a rare complication from an intrauterine contraceptive dev
ice (IUD) which caused deviation of the right ureter in a 31-year-old woman
who presented with complaints of insomnia and abdominal pain. Our case sho
ws that perforation of the uterus by an IUD can cause a silent urological c
omplication. The possibility of ureteral involvement and displacement shoul
d be kept in mind in a woman in whom a missing IUD is encountered. Copyrigh
