Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
This is particularly important after pelvic reconstructive surgery, as reported rates of UTI reach up to 20-25%. Urinary retention requiring short-term indwelling catheterization, common in these women, contributes to the risk of UTIs by increasing the risk of bacteriuria by 5-10% per day and through the dislodging of bacterial colonies during catheter removal. Balancing prevention and resistance and cost is key. A meta-analysis by Marschall et al indicated the benefit of a short dose of antibiotic prophylaxis at catheter removal in general post-surgical patients. However, data is lacking on the effects of daily antibiotic prophylaxis on resistance and cost.
A possible alternative to antibiotics presents itself in methenamine hippurate, a urinary antiseptic which forms formaldehyde in the presence of acidic urine. It is relatively inexpensive, and does not induce resistance in vivo. Prior studies have shown that daily use of methenamine can decrease the risk of post-operative UTI.
The purpose of our study was to investigate the efficacy of a short course of methenamine hippurate at catheter removal to that of a short course of ciprofloxacin in prevention of UTIs after short-term indwelling catheterization. Additionally, we investigated factors that influence post-operative UTIs, the rate of culture-proven UTIs after prophylaxis, the antibiotic resistance profile of those undergoing prophylaxis, and the cost effectiveness of prophylaxis.

Study Groups

Methenamine
Methenamine hippurate is a medication that exhibits antibacterial activity by converting to formaldehyde in the presence of acidic urine. It is currently FDA approved for the prophylaxis of recurrent urinary tract infections. It has been previously used in studies for prevention of UTI after gynecologic surgery. Dosage will be methenamine hippurate 1g, 1 tablet by mouth every 12 hours for 24 hours (total of two doses), with the first dose taken at least one hour prior to catheter removal.

Ciprofloxacin
Ciprofloxacin is a commonly used antibiotic commonly used for prevention of UTI after catheterization. It belongs to a class of antibiotics known as the fluoroquinolones. Dosage will be ciprofloxacin 500 mg, 1 tablet by mouth every 12 hours for 24 hours (total of two doses), with the first dose taken at least one hour prior to catheter removal.
