Purpose:
To evaluate the risk of infectious complications associated with the use of ciprofloxacin (CIP) or fosfomycin-trometamol (FMT) for antibiotic prophylaxis in patients undergoing transrectal prostate biopsy (TrBx).
Methods:
A retrospective, single-centre analysis was conducted, including patients who underwent TrBx from 2015 to 2023 and received CIP or FMT for antimicrobial prophylaxis. The primary endpoint was symptomatic urinary tract infections within 30 days after TrBx, and the secondary endpoint was hospitalization due to infectious complications. Logistic regression was used to assess the risk of infection, adjusted for variables such as age, prostate size and comorbidities. Hospitalization rates were compared using the chi-square test.
Results:
Overall, 913 patients were eligible for inclusion, of whom 491 had received CIP and 422 had received FMT. Infectious complications occurred in 38/913 (4.2%) of all patients, 12/491 (2.4%) of whom had received CIP and 26/422 (6.2%) of whom had received FMT. Multivariable analysis revealed a significantly greater risk of infectious complications with FMT (adjusted odds ratio 2.99, 95% CI 1.39-7.16, p = 0.008) compared to CIP. Hospitalization rates were similar in the CIP group (8/12, 66.6%) and FMT group (14/26, 53.5%, p = 0.7), but one death occurred due to fulminant sepsis in the FMT group.
Conclusion:
Compared with CIP, FMT prophylaxis is associated with a greater risk of infectious complications and should be used cautiously in routine clinical practice. Given the uncertainty of FMT's efficacy in preventing infections after TrBx, alternative antibiotic regimens should be preferred, or transitioning to the transperineal biopsy approach may further reduce infection risk and support antibiotic stewardship.
Insights
Fosfomycin-trometamol (FMT) prophylaxis for transrectal prostate biopsy (TrBx) carries a higher risk of infectious complications compared to ciprofloxacin (CIP). Clinicians should exercise caution with FMT and consider alternative antibiotics or biopsy methods.
Area of Science:
- Urology
- Infectious Diseases
- Pharmacology
Background:
- Transrectal prostate biopsy (TrBx) is a common procedure for diagnosing prostate cancer.
- Antibiotic prophylaxis is crucial to minimize infectious complications following TrBx.
- Ciprofloxacin (CIP) and fosfomycin-trometamol (FMT) are commonly used prophylactic agents.
Purpose of the Study:
- To compare the risk of infectious complications between CIP and FMT prophylaxis in patients undergoing TrBx.
- To evaluate the incidence of symptomatic urinary tract infections and hospitalizations post-TrBx.
Main Methods:
- Retrospective, single-centre analysis of 913 patients undergoing TrBx from 2015-2023.
- Patients received either CIP or FMT for antibiotic prophylaxis.
- Primary endpoint: symptomatic UTIs within 30 days; Secondary endpoint: infectious complication hospitalizations. Logistic regression and chi-square tests were used for analysis.
Main Results:
- Infectious complications occurred in 4.2% of all patients (2.4% with CIP vs. 6.2% with FMT).
- FMT prophylaxis was associated with a significantly higher risk of infectious complications (aOR 2.99, p=0.008).
- One death from sepsis occurred in the FMT group; hospitalization rates were similar between groups.
Conclusions:
- FMT prophylaxis is linked to an increased risk of infectious complications after TrBx compared to CIP.
- Cautious use of FMT is recommended; alternative antibiotic regimens or transperineal biopsy may be preferable.
- Further research is needed to clarify FMT efficacy and optimize antibiotic stewardship for TrBx.
