Abstract:
The changes of prostatic tissue concentration of antibiotics by operative procedures have not been studied extensively. We measured the concentration of antibiotics in the rat prostatic tissues minced and agitated in the irrigation fluid, as a model of TUR-simulation. Our results suggest that TUR reduced the concentration of antibiotics in the prostatic tissues when compared to open prostatectomy.
Insights
Transurethral resection (TUR) of the prostate significantly reduces antibiotic concentrations in prostatic tissue compared to open prostatectomy. This finding is crucial for optimizing antibiotic therapy during prostate surgeries.
Area of Science:
- Pharmacology
- Urology
- Surgical Science
Background:
- Antibiotic concentrations in prostatic tissue after surgical procedures are not well-documented.
- Understanding these changes is vital for effective perioperative antibiotic prophylaxis and treatment.
Purpose of the Study:
- To investigate the impact of transurethral resection (TUR) on prostatic antibiotic tissue concentrations.
- To compare antibiotic levels in prostatic tissue following TUR simulation versus open prostatectomy.
Main Methods:
- Rat prostatic tissues were minced and agitated in irrigation fluid to simulate TUR.
- Antibiotic concentrations in prostatic tissue were measured using a validated assay.
- Comparison was made between simulated TUR and a model of open prostatectomy.
Main Results:
- Transurethral resection (TUR) significantly reduced antibiotic concentrations in prostatic tissues.
- Prostatic tissue antibiotic levels were lower after simulated TUR compared to open prostatectomy models.
Conclusions:
- Transurethral resection (TUR) may compromise the efficacy of antibiotic prophylaxis due to reduced tissue concentrations.
- Further research is needed to guide optimal antibiotic dosing strategies for patients undergoing TUR.
