ePub - Transrectal prostate biopsy (TRPB) is widely used for the diagnosis of prostate cancer but carries a clinically meaningful risk of infectious complications due to inoculation and translocation of rectal flora into the urinary tract and bloodstream. Antibiotic prophylaxis remains central to preventing febrile urinary tract infection and sepsis; however, increasing antimicrobial resistance—particularly fluoroquinolone-resistant Enterobacterales—has reduced the reliability of conventional empirical regimens in many regions. In this narrative review, we searched PubMed/MEDLINE, Embase, and Scopus for relevant literature published through February 2026 and synthesized current guideline positions and selected clinical evidence on prophylactic regimens, resistance-adapted regimen selection, and adjunctive measures for TRPB. Cumulative evidence indicates that the efficacy of fluoroquinolone monotherapy has significantly declined in regions with high-resistance prevalence. Alternative or augmented strategies (e.g., cephalosporin- or fosfomycin-based approaches) may reduce infectious complications in selected settings, although their performance appears context-dependent and may be accompanied by shifts in pathogen distribution. Rectal swab-guided targeted prophylaxis can individualize antibiotic selection; however, its effectiveness varies across studies because of methodological heterogeneity and imperfect prediction of clinical outcomes. Technique-based prevention, most notably transperineal biopsy, may reduce infectious risk while decreasing reliance on broad-spectrum prophylaxis. Taken together, infection prevention after prostate biopsy should be individualized according to local susceptibility patterns and patient-level risk while integrating antimicrobial stewardship and selecting adjunctive or technique-based measures when feasible.
