title: Urinary tract infection before and after mid-urethral slings: culture-proven diagnosis and analysis of risk factors.
abstract: OBJECTIVE
  To study prevalence of UTI in women with SUI before and after mid-urethral slings based on culture-proven diagnosis.
  
  
  METHODS
  Clean catch midstream urine samples were collected and sent for agar culture in 150 patients before and on follow-up after mid-urethral slings visit. Degree of agreement between culture-proved UTI and clinically suspected was assessed. In addition, risk factors for UTI were analyzed.
  
  
  RESULTS
  Preoperative culture was positive in 9 (6%) patients, 7 of them were asymptomatic. UTI was primarily diagnosed in 39 (26%) patients suggested by symptoms. No bacterial growth was detected at first postoperative day. There were 6 out of 62 (9.7%) patients who had positive urine cultures at follow-up visits, all of them were symptomatic. Eleven (18%) patients were diagnosed as UTI, based on clinical suspicion.
  
  
  CONCLUSIONS
  In contrast to UTI before surgery, asymptomatic UTI is unlikely to happen after mid-urethral sling.
