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.

The emergence and spread of antibiotic-resistant bacteria have been reported for various infections. Infections caused by such bacteria are associated with higher rates of patient morbidity and mortality, and increased healthcare costs. In our urological community, we have observed fluoroquinolone resistance in clinical strains of Escherichia coli isolated even from young women with acute uncomplicated cystitis. 1 We have increasingly encountered some bacterial species that produce an extended spectrum β-lactamase in patients with complicated urinary tract infections.2 In male urethritis, oral regimens of fluoroquinolones or third-generation cephalosporins are no longer recommended for treatment of gonorrhea because of antibioticresistant Neisseria gonorrhoeae. 3In the urological community, clinical practice guidelines exist for antibiotic treatment and prophylaxis. The 2006 guidelines for perioperative antimicrobial prophylaxis in urological surgery were approved by the Japanese Urological Association (JUA).4 A survey on antimicrobial prophylaxis reported that of the principal JUA-certified urological training institutions, 6.5% "completely" and 69.7% "mainly" followed the guidelines. However, the guidelines were followed in 48.5% of open clean operations, 43.2% of prostate biopsies and 42.2% of cystoscopies.
Objectives: To determine practice patterns of prescribing prophylactic antibiotics against urinary tract infection (UTI) for urodynamic studies (UDS) and outpatient cystoscopy in women. Design: A cross-sectional survey study was conducted of North American female pelvic medicine and reconstructive specialists (FPMRS). Methods: An online survey was used to assess prophylactic prescribing patterns of FPMRS specialists that perform UDS and outpatient cystoscopy. This survey was developed and then electronically disseminated through the American Urogynecologic Society to 699 eligible physicians. Results: A total of 138 surveys were completed. Approximately half of physicians did not prescribe any antibiotic prophylaxis for UDS or for cystoscopy (54% and 43%, respectively). For patients with perceived risk factors (recurrent urinary tract infections, immunosuppression, known neurogenic lower urinary tract dysfunction, indwelling catheter use, elevated post void residual/bladder outlet obstruction, genitourinary anomalies, and diabetes), 32% and 41% of physicians prescribed antibiotic prophylaxis for UDS and cystoscopy, respectively. A minority of physicians always prescribed antibiotics for UDS and cystoscopy (13% and 17%, respectively). Limitations: The response rate was a limitation of the study, however, this rate is in keeping with other physician survey studies published within this subspecialty. Selection and response biases may have contributed to the results of this survey study. Conclusion: There was no uniform approach to urinary tract infection prophylaxis for UDS and outpatient cystoscopy in women which reflects the lack of current guidelines and the low level of evidence on which they are based. This non-uniform practice calls for more research to better define an evidence-based standard of care.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
