What this trial studies

This is a double-blind, placebo-controlled randomized trial designed to evaluate the effectiveness of Vitamin C supplementation in preventing catheter-associated urinary tract infections (CAUTIs) in women undergoing elective gynecological surgeries. The study targets women who are at a higher risk for UTIs due to the nature of these surgeries and the use of catheters. Participants will receive either 1000 mg of Ascorbic Acid or a placebo, and the incidence of UTIs will be monitored post-surgery. The goal is to determine if Vitamin C can significantly reduce the occurrence of UTIs in this vulnerable population.

Who should consider this trial

Good fit: Ideal candidates for this study are nonpregnant women aged 18 and older who are scheduled for elective gynecological surgery.

Not a fit: Patients who may not benefit from this study include those with existing urinary tract infections, certain medical conditions like diabetes or renal disorders, or those already taking Vitamin C supplements.

Why it matters

Potential benefit: If successful, this study could provide a simple and cost-effective method to reduce the incidence of urinary tract infections in women after gynecological surgeries.

How similar studies have performed: While there is limited strong clinical evidence supporting the use of Vitamin C for UTI prevention, this approach has been suggested in other contexts, making this study a novel exploration.
