title: [Bladder lithiasis formed from an IUD. A rare case].
abstract: OBJECTIVE
  To describe an uncommon case of bladder calculus arising from an intrauterine device (IUD).
  
  
  RESULTS
  A female patient with an IUD for the past 10 years consulted for frequent episodes of cystitis. Patient evaluation demonstrated a bladder calculus that warranted surgery. Treatment was by cystolithotomy, which disclosed a 6 cm calculus attached to the IUD.
  
  
  CONCLUSIONS
  Bladder calculus arising from an IUD is rare. The case described herein was successfully managed by cystolithotomy.
