Although febrile complications are rarely encountered after a prostate biopsy procedure, in recent years the number of cases of fatal infection after that have increased along with increases in resistant bacteria. The available biopsy approaches are transrectal and transperineal, with the transrectal approach primarily used. As the invasion path of the puncture needle differs between these approaches, pretreatment and the method of administration of preventive antimicrobial drugs should be separately considered for infection prevention. Recently, the Japanese guidelines for perioperative infection prevention in the field of urology were revised after receiving approval from the Japanese Urological Association. With use of the transrectal approach, attempts have been made to selectively administer prophylactic antibiotics by confirming the presence or absence of resistant bacteria in rectal swab culture results before carrying out a prostate biopsy procedure because of potential problems associated with resistant bacteria in rectal flora. For preventive antibiotics, a single dose of oral quinolone is recommended for patients with low risk, whereas daily administrations of piperacillin/tazobactam are recommended for those considered to be high risk. In contrast, for the transperineal procedure, a single dose of oral quinolone is recommended as a preventive antibiotic. With both approaches, it is important to empirically administer broad-spectrum antimicrobials when occurrence of a febrile infection after a prostate biopsy procedure is confirmed.
