Official title

Vitamin C for the Prevention of Catheter-associated Urinary Tract Infections in Women Who Undergo Elective Gynecological Surgeries: a Randomized Double-blinded Controlled Trial

Overview

Double-blind placebo-controlled randomized trial aiming to assess the role of Vitamin C supplementation in the prevention of catheter-associated urinary tract infections in women undergoing elective gynecological surgeries.

Detailed description

Women undergoing Elective GYN surgery are a particularly high-risk group for UTIs, because these operations involve surgery adjacent to the bladder and delayed bladder emptying is common. It has been estimated that the 'risk of Urinary tract infections among women undergoing elective Gynecologic GYN surgery is between 10-64%, following catheter removal. Catheterization, in itself, poses a significant risk for UTIs because insertion and removal introduce bacteria and cause trauma, both of which may increase the risk of UTIs. The incidence of UTI for women in the general population is estimated to be 3-4% per year vs 5% per day of catheterization. For this reason, multiple interventions have been studied for the prevention of UTIs. Ascorbic acid (vitamin C) is often suggested as a supplement that can prevent recurrent UTIs by acidification of the urine. Strong clinical evidence to support this claim in healthy adult women is lacking. Because of the lack of literature regarding the use of Vitamin C as a prophylactic agent for the prevention of UTIs, the investigators wish to conduct this study to assess the potential therapeutic efficacy of Ascorbic acid in preventing UTIs after elective GYN surgery.

Interventions

  • Drug Ascorbic Acid 1000 MG
    1000mg Ascorbic acid orally daily started on the day of elective gynecological surgery for 10 days
