Abstract:
The incidence of catheter-associated urinary tract infections (UTIs) becomes higher with prolongation of the indwelling period of a catheter. As to the entry of bacteria, ascending UTIs have now attracted attention. In the present study. the metal area was examined bacteriologically and the possibility to use antiseptics for blocking the route of developing infections was investigated. The subjects included 72 patients with an indwelling, urethral catheter inserted post-operatively. These patients were divided into three groups treated with once or twice daily application of povidone-iodine or once daily application of povidone-iodine cream. In these groups, the relation between changes in isolation of bacteria from the meatal area and the incidence of UTI was evaluated. It was found that reduction in bacterial count by antisepsis is effective to prevent ascending UTIs. Moreover, once daily application of povidone-iodine was proven to be effective in male patients. The effective antisepsis in females was twice daily application of povidone-iodine.
Insights
Reducing bacteria at the catheter insertion site with antiseptics can prevent urinary tract infections (UTIs). Povidone-iodine application, once or twice daily, proved effective in preventing catheter-associated UTIs in patients.
Area of Science:
- Urology
- Infectious Diseases
- Antimicrobial Stewardship
Background:
- Catheter-associated urinary tract infections (UTIs) increase with prolonged catheter use.
- Ascending bacterial entry is a significant concern for UTIs.
Purpose of the Study:
- To investigate the effectiveness of antiseptics in preventing catheter-associated UTIs.
- To evaluate bacterial load in the meatal area and its relation to UTI incidence.
Main Methods:
- Bacteriological examination of the meatal area in 72 post-operative catheterized patients.
- Three treatment groups: povidone-iodine (once/twice daily) and povidone-iodine cream (once daily).
- Correlation analysis between bacterial isolation and UTI incidence.
Main Results:
- Antisepsis significantly reduced bacterial counts, proving effective in preventing ascending UTIs.
- Once-daily povidone-iodine was effective for male patients.
- Twice-daily povidone-iodine was effective for female patients.
Conclusions:
- Antiseptic application is a viable strategy to reduce bacterial colonization and prevent catheter-associated UTIs.
- Tailored antiseptic regimens (once daily for males, twice daily for females) optimize UTI prevention.
