The Prevalence and Type of Urinary Tract Infection in Patients with Urethral Catheter in Urology Department of Imam Reza Hospital

Abstract

Backgrounds and Objectives: Urethral catheter is used for about 15 to 20% of hospitalized patients during their short-term hospitals stay which can predispose them to urinary tract infection (UTI). The aim of this study was to evaluate the prevalence and type of UTI in patients with urethral catheter at urology ward and role of antibiotic in the prevention of catheter related UTI. Materials and Methods: From October 2012 to March 2013, all catheterized patients in urology department of Imam Reza Hospital, Tabriz University of Medical Sciences were enrolled to this cross sectional study. Urine culture was detected from one hundred patients before catheterization and 1, 3 and 7 days after catheterization and urine-analysis with urine culture were performed for all samples. Results: 100 patients (95 male and 5 female) with folly urethral catheter in post urology operation were evaluated. The mean age of the patients was 67.04 ± 9.29 years. Mean hospitalization duration was 7.05 ± 0.97 day. Mean negative culture period of patients was 2.90 ± 1.99 days. Urinary culture was positive in 20% of the patients. A second and third urinary culture was positive in 5% and 6% of patients, respectively. E. coli was isolated from 30%, 60% and 66.7% of the samples on first, second and third days, respectively. Conclusion: Prevalence rate of positive urinary culture was increased in patients with urethral catheter. E.coli was the most common isolated organism. Therefore, an appropriate antibiotic therapy should be used for the hospitalized patients. Unnecessary catheterization should be avoided and the health professionals have to follow the recommendations of the catheterization guidelines.
