title: [Double bladder lithiasis from an intrauterine device. Report one case].
abstract: OBJECTIVE
  To report a new case of an intrauterine device causing bladder lithiasis, because of its rarity as a complication of the intrauterine device contraceptive method.
  
  
  RESULTS
  27-year-old female patient admitted in the urology department of the "Hospital Medico-quirurgico 10 de Octubre" who having an intrauterine device was pregnant, underwent a caesarean section, and a new intrauterine device implant, and a few months later presented with lower urinary tract infectious syndrome, being diagnosed of double bladder lithiasis secondary to intrauterine device migration, for which cystolithotomy was performed.
  
  
  CONCLUSIONS
  We performed a short review of the bladder foreign bodies reported in the literature, and present this case which is very infrequent because of the finding of 2 stones in the bladder and an intrauterine device inside one of them. The intrauterine device was detected after crushing one of the calculi, 2 cm in size. It seems that first intrauterine device had migrated through the uterine wall into the bladder, creating a calcareous concretion around.
