Antibiotic Prophylaxis for Transrectal Prostate Biopsy
United States563 participantsStarted 2012-08
Plain-language 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.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* Ability and willingness to provide written informed consent.
* All individuals who will undergo TRUSP as part of their standard of care are eligible for study.
Exclusion Criteria:
* Men under 30 years of age
* Individuals whose rectal swab indicates that they harbor CS-GNB who cannot receive ciprofloxacin as pre-procedure prophylaxis for any reason
* Individuals whose rectal swab indicates that they harbor CR-GNB who cannot abide by the antimicrobial prophylaxis guidelines outlined in the study protocol for any reason
* Individuals who do not wish to complete the pre-procedure risk factor questionnaire or the two post-procedure phone questionnaires to assess for infectious complications
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
