Summary

This study will include 2,600 adults scheduled for bladder tumor surgery. Half will get a standard urine culture before surgery; the other half will not. The goal is to see if skipping the test leads to more fevers or infections in the month after surgery. If it's safe, it could save time and resources.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

What this could lead to: If successful, this could simplify pre-surgery preparation for bladder tumor patients, reducing delays and healthcare costs without increasing infection risk.
What could go wrong: This is an early-stage trial (not yet recruiting) comparing two standard approaches, so results may not change practice if infection rates rise without urine cultures.
