Summary
Post-prostatectomy infections are often caused by urethral bacteria, not prostate bacteria. This study identified common urethral colonizers and introduced a new prostate sampling technique.
Area of Science:
- Urology
- Infectious Diseases
- Microbiology
Background:
- Post-prostatectomy infections pose a significant clinical challenge.
- Understanding microbial colonization patterns is crucial for preventing surgical site infections.
Purpose of the Study:
- To identify organisms colonizing the urethra and prostate.
- To investigate the role of these organisms in post-prostatectomy infections.
- To introduce a novel method for prostate sampling.
Main Methods:
- Prospective trial involving 25 patients undergoing prostatectomy.
- Monitoring of urethral and prostatic colonization.
- Identification of causative organisms in postoperative infections.
- Development and description of a new prostate sampling technique.
Main Results:
- Six out of 25 patients developed postoperative infections.
- Causative organisms were previously found in the urethra, but not the prostate.
- High rate of urethral colonization by streptococci (14/25 patients).
- Low incidence of prostatic colonization observed.
Conclusions:
- Urethral colonization, particularly by streptococci, is a significant risk factor for post-prostatectomy infections.
- Prostatic colonization appears less common or relevant in this context.
- The novel prostate sampling method warrants further evaluation for clinical utility.
