Testing antibiotics for preventing infections after bladder surgery

Prophylactic Antibiotics in Radical Cystectomy With Urinary Diversion

EARLY_PHASE1 · University of Minnesota · NCT06190197

This study tests whether giving antibiotics before bladder surgery can help prevent infections in patients with muscle-invasive bladder cancer compared to not using antibiotics at all.

What this trial studies

This study evaluates the effectiveness of prophylactic antibiotics in preventing postoperative urinary tract infections in patients undergoing radical cystectomy for muscle-invasive bladder cancer. It employs a randomized two-arm design to compare the rates of infections in patients receiving nitrofurantoin versus those receiving no antibiotics. The study aims to determine if avoiding antibiotics is non-inferior in terms of infection rates within 90 days post-surgery. Participants must be 18 years or older and meet specific eligibility criteria related to their health status and cancer diagnosis.

Who should consider this trial

Good fit: Ideal candidates are adults with muscle-invasive bladder cancer scheduled for radical cystectomy with urinary diversion.

Not a fit: Patients currently on antimicrobials for active infections or with poor renal function may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could reduce unnecessary antibiotic use and its associated risks while maintaining patient safety.

How similar studies have performed: Other studies have explored antibiotic prophylaxis in surgical settings, but this specific comparison of non-use versus nitrofurantoin is relatively novel.
