To study the prevalence of fluoroquinolone-resistant (FQ-resistant) and extended-spectrum β-lactamase-producing (ESBL-producing) bacteria in the rectums of patients undergoing transrectal ultrasound-guided prostate biopsy (TRUS-Bx), identifying predictive factors for such carriage and to correlate with the microbiology of those who developed postbiopsy infection (PBI). ⋯ A high prevalence of FQ-resistant and ESBL-producing rectal flora in Chinese men undergoing TRUS-Bx was found. Diabetes mellitus and prior antimicrobial use within 5 years were significant predictors for resistant bacterial carriage. Despite the high-resistant bacteria prevalence, PBI rate remained low. A targeted approach of antimicrobial prophylaxis using prebiopsy culture swab in areas with high prevalence of resistant bacteria should be further investigated.
