Is preoperative urine culture before TURB necessary for preventing fever UTIs?

Official title: Relevance of the Urine Bacterial Culture Performed Before TransUrethral Resection of the Bladder for Post-operative Febrile Urinary Tract Infections Prevention: a Non-inferiority Randomized Controlled Trial

Run by Poitiers University Hospital · NCT07463963 · Data updated 2026-11-12

This trial tests whether skipping the preoperative urine culture before TURB is as safe as doing it, by comparing febrile urinary tract infections in the 30 days after surgery.

Is this trial a fit for you?

Likely a good fit

Adults 18 or older scheduled for TURB for suspected or confirmed bladder tumor, able to consent, and affiliated with social security.

Probably not a fit

Patients with active UTI at screening or undergoing planned combined surgery may not benefit and could be excluded.

What this trial studies

This is a non-inferiority randomized trial evaluating whether omitting routine preoperative urine culture (UC) before transurethral resection of the bladder (TURB) is not worse than performing the culture in preventing postoperative febrile UTIs. Participants are adults scheduled for TURB to treat or diagnose bladder tumors and are randomized to either receive a preoperative UC or not. All participants are followed for 30 days after surgery to track incidence and severity of febrile UTIs, with safety and antibiotic-use patterns monitored. The study context notes that current guidelines recommend UC screening, but high-quality evidence showing benefit is lacking. The trial is conducted at multiple French centers with Poitiers University Hospital as the lead sponsor.

Why it matters

Potential benefit: If non-inferiority is shown, patients could avoid unnecessary preoperative urine testing and related antibiotic use without increasing infection risk.

How similar studies have gone: Previous observational data have questioned the necessity of preoperative UC, but high-quality randomized evidence is limited; this trial aims to provide more definitive results.
