title: Bladder calculus presenting as recurrent urinary tract infections: a late complication of cervical cerclage placement: a case report.
abstract: BACKGROUND
  A cervical cerclage is often placed for women with cervical shortening or insufficiency. There are early and late complications of cervical cerclage placement, but they rarely involve the lower urinary tract. We present a case of a lower urinary tract complication from this procedure presenting as recurrent urinary tract infections.
  
  
  METHODS
  A 43-year-old woman with a history of cerclage placement during her second pregnancy (10 years prior) presented with recurrent urinary tract infections and hematuria. Radiologic imaging and cystoscopy revealed a 2-cm bladder stone attached to suture that was subsequently removed during cystoscopy.
  
  
  CONCLUSIONS
  Retained suture from a cervical cerclage can act as a nidus for bladder stone formation.
