Clinical Scorecard: Reducing Infection Risk Through Povidone-Iodine Rectal Disinfection Before Transrectal Prostate Biopsy: A Comprehensive Systematic Review and Meta-Analysis
At a Glance
Category
Detail
Condition
Infectious complications following transrectal ultrasound-guided prostate biopsy (TRUS-PB)
Key Mechanisms
Rectal disinfection with povidone-iodine (PI) reduces bacterial translocation during TRUS-PB, lowering infection risk
Urology outpatient or hospital settings performing prostate biopsies
Key Highlights
TRUS-PB is associated with up to 6.3% incidence of infectious complications including fever, acute bacterial prostatitis, and sepsis.
Povidone-iodine rectal disinfection prior to TRUS-PB significantly reduces infectious complications compared to no PI use.
Combination of PI disinfection with antibiotic prophylaxis (AP) shows improved infection control, though efficacy in reducing sepsis requires further clarification.
Guideline-Based Recommendations
Diagnosis
Use clinical criteria including fever (>37.8–38.5°C) and sepsis definitions per international consensus to identify infectious complications post-TRUS-PB.
Management
Apply rectal disinfection with povidone-iodine prior to TRUS-PB to reduce infection risk.
Administer prophylactic antibiotics, commonly fluoroquinolones or β-lactams, alongside PI disinfection for enhanced protection.
Monitoring & Follow-up
Monitor patients post-biopsy for signs of fever and sepsis within one week.
Use standardized definitions for fever and sepsis to ensure consistent assessment.
Risks
Recognize that TRUS-PB carries a risk of infectious complications due to rectal bacterial translocation.
Consider antibiotic resistance patterns when selecting prophylactic antibiotics.
Patient & Prescribing Data
Patients undergoing TRUS-PB, including those receiving various prophylactic antibiotics
Most RCTs included antibiotic prophylaxis with PI disinfection; fluoroquinolones and β-lactams were common. PI plus AP reduced infection rates more than AP alone, though sepsis reduction data remain inconclusive.
Clinical Best Practices
Perform rectal disinfection with povidone-iodine immediately before TRUS-PB.
Combine PI disinfection with appropriate antibiotic prophylaxis tailored to local resistance patterns.
Use standardized definitions for fever and sepsis to monitor post-biopsy infectious complications.
Prefer transperineal biopsy when feasible, but if TRUS-PB is performed, implement PI disinfection to mitigate infection risk.
