Secondary vesical calculus following translocated IUCD in urinary bladder

We describe an uncommon case of bladder calculus arising from a translocated intrauterine contraceptive devise (IUCD) in a 36-year-old female patient with a 5-year-old IUCD who consulted for recurrent episodes of cystitis. Her evaluation established a bladder calculus that warranted surgery. She underwent a cystolithotomy, which dislodged a calculus (8×6×4 cm) that was attached to the IUCD. This is very rare.
