  Purpose
Approximately 10-27% of patients undergoing gynecologic surgeries develop a catheter associated urinary tract infection (CAUTI) in the post operatory period, as bladder catheterization is a common practice in gynecologic surgery. Cranberry products provide alternative means for preventing CAUTI and could result in decreased use of antimicrobials. In this pilot study we will enroll 200 women post gynecologic surgery and randomize them to take either cranberry powder capsules or placebo powder capsules. The low risk of harm associated with using cranberry to reduce UTI coupled with its potential benefit makes it a desirable intervention for the prevention of CAUTI. The conduct/ results of this pilot /feasibility study will prepare us for the conduct of a large scale clinical trial.

Primary Outcome Measures:
  • Participants With Clinically-diagnosed and Treated UTI's. [ Time Frame: From surgery to post-op visit, approximately 6 weeks post surgery ]
    The primary endpoint was the number of participants who were clinically-diagnosed and treated for UTI whether or not results from a urine culture were available. All UTI's were confirmed via medical records.


Enrollment: 200
Study Start Date: June 2011
Study Completion Date: October 2013
Primary Completion Date: May 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Cranberry powder capsules

TheraCran® cranberry: based upon proanthocyanidin content, the four cranberry capsules are equivalent to two 8-ounce servings of cranberry juice.

Participants were directed to take two capsules by mouth twice each day (once in the morning and once in the evening) starting at time of discharge for 4-6 weeks, or until their return for their post-operative doctor's visit. Participants were instructed to drink an 8 oz glass of water while taking the capsule with or without food.

Drug: Cranberry powder capsules
2 cranberry powder capsules twice a day
Other Name: TheraCran
Placebo Comparator: Placebo capsules
Placebo: participants were directed to take two capsules by mouth twice each day (once in the morning and once in the evening) starting at time of discharge for 4-6 weeks, or until their return for their post-operative doctor's visit. Participants were instructed to drink an 8 oz glass of water while taking the capsule with or without food.
Drug: Placebo powder capsules
2 placebo capsules twice a day

Detailed Description:
Cranberry products prevent bacteria that cause UTI, especially Escherichia coli, from adhering to bladder cell wall thus preventing infection. Adherence of type 1 pili is inhibited by the fructose and of p pili by the proanthocyanidins present in cranberry.
