title: Intravesicular pressure monitoring does not cause urinary tract infection.
abstract: OBJECTIVE
  To determine whether intravesicular pressure monitoring using a closed system increases the risk of nosocomial urinary tract infection.
  
  
  METHODS
  Retrospective chart and database review.
  
  
  METHODS
  Surgical/trauma intensive care units of a regional level-I trauma center.
  
  
  METHODS
  3108 critically ill patients of which 122 patients underwent intravesicular pressure monitoring.
  
  
  METHODS
  Severity-adjusted urinary tract infection rates were compared among patients with and without intravesicular pressure monitoring.
  
  
  RESULTS
  Over a 24-month period, 122 consecutive patients had 2202 intravesicular pressure measurements performed. During 1448 urinary catheter days, 15 patients who required intravesicular pressure monitoring developed a urinary tract infection with a severity-adjusted device-related infection rate of 7.9 infections per 1000 catheter days. Of the 2986 patients who did not require such monitoring, 98 patients developed a urinary tract infection with an infection rate of 6.5 infections per 1000 catheter days (p=0.56).
  
  
  CONCLUSIONS
  Intravesicular pressure monitoring using the closed transducer technique is safe and does not increase the risk of urinary tract infection.
