    Abstract:
    AIM: The aim of this study was to investigate the effectiveness of antimicrobial-coated catheters against bacteriuria and urinary tract infection in patients who have urinary catheterization. METHODS: Twenty eight and twenty six people similar in terms of demographic characteristics and primary and underlying diseases were randomly selected from patients undergoing short-time urinary catheterization in the intensive care unit. Silver-coated slicone foley catheters and normal slicone foley catheters were used for uninary catheterization in the first and second group of the patients respectively. Urine specimens were collected from patients at 2-day intervals and assessed in terms of bacteriuria. RESULTS: Bacteriuria was found in 12 (46.2%) of the patients using normal catheters and 13 (46.4%) of those using silver-coated catheters throughout the monitoring period. No significant relationship was determined between use of different catheter types and bacteriuria (p = 0.98). The most common microorganism was identified as E. coli in the normal catheter group while microorganism other than E. coli was identified in the silver-coated catheter group. The prevalence of bacteriuria was statistically significantly higher in patients with a history of hospitalization in the previous 3 months (p = 0.028). CONCLUSION: The use of silver-coated silicone catheters was not shown to have a protective effect against bacteriuria in this study. Further well-designed studies with larger case numbers are now needed to confirm whether history of hospitalization, which emerged as a statistically significant factor in this study, increases the prevalence of catheter-related bacteriuria.
