Summary

This study tests whether taking a daily vitamin C pill for 10 days can prevent catheter-associated urinary tract infections in women having elective gynecologic surgery. Half of the 180 participants will receive vitamin C, and half will receive a placebo. The goal is to see if this simple, low-cost approach reduces the number of infections.

What this could mean

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

Active substance
Vitamin C (ascorbic acid) 1000 mg daily
What this could lead to
If it works, this could offer a simple, low-cost way to prevent urinary tract infections after gynecologic surgery, reducing antibiotic use.
What could go wrong
This is a small phase 2 trial, so results may not be conclusive. Vitamin C may not prevent infections effectively, and some people may experience side effects like stomach upset or kidney stones.
