title: [Is prophyilaxis necessary after urodynamic tests? Our experience].
abstract: Urodynamic studies should be performed only on patients with sterile urine. The use of prophylaxis after urodynamic investigation is debated (positive urinoculture in 9 to 15% of cases). The Units of Urodynamics at the Urological Clinic of the University of Genoa and of the Galliera Hospital of Genoa assessed the prevalence of bacteriuria on a sample of 336 patients (314 females and 22 males), average age 62.3, between January and December 2006. All patients with sterile urine before examination underwent a complete urodynamic test. Concomitant diseases were: diabetes (7.7%), multiple sclerosis (3.5%), Parkinson's disease (1.2%), urinary retention treated by autocatheterism (1.2 %). Urinoculture was performed seven days after the urodynamic study. All patients were asymptomatic; 40/336 urinocultures were positive (E. coli 80%, Proteus M. 10%, other 10%). The prophylaxis does not eliminate but only reduces post-urodynamic infections; we believe that the cost-benefit ratio is unfavorable.
