Study Summary

This study is being conducted in men scheduled to undergo transrectal ultrasound-guided prostate biopsy (TRUSP). Traditionally prior to prostate biopsy, an antibiotic, ciprofloxacin, has been given to men to prevent biopsy-related infections. In recent years as ciprofloxacin resistance has increased in the community, more and more men are becoming infected with ciprofloxacin-resistant bacteria after prostate biopsy. This study is being done to determine if obtaining rectal swab cultures and choosing antibiotics based on these culture results will result in fewer infectious complications than giving all men ciprofloxacin. The investigators will compare 2 groups: men whose rectal swabs do not show ciprofloxacin-resistant bacteria will receive ciprofloxacin prior to biopsy, and men whose swabs do show ciprofloxacin-resistant bacteria will receive alternative antibiotics based on their culture results. Our hypothesis is that these 2 groups will have equal numbers of post-biopsy infectious complications and both groups will have fewer infectious complications than a historical group who received empiric ciprofloxacin without the benefit of rectal swab culture results.

Primary Outcome

To measure and compare the rates of infection following TRUSP in subjects with and without CR-GNB. This measure is number of participants with post-biopsy infection.
