Comparison of catheter-associated bacteriuria and urinary tract infections between designed sheathed urethral catheters versus other methods of urinary drainage

Introduction: One of the most common nosocomial infections is urinary tract infection (UTI) which more commonly occurs in patients with urethral catheter. Objectives: The aim of this study is to compare the incidence rate of catheter-associated bacteriuria (CRB) and UTI between sheathed designed catheters versus other methods of urinary drainage. Patients and Methods: In this randomized double-blind controlled trial, 150 male patients, who needed urethral catheter, were randomly assigned into three groups; condom bag, designed sheath catheter and traditional Foley catheter. The midstream urine samples were sent to laboratory to evaluate bacteriuria immediately after catheter insertion, upon catheter removal and after two weeks consequently. Results: The mean age of patients was 51.28 ± 14.12 years. The frequency of bacteriuria in patients was 19 (38%), 10 (20%) and 10 (20%) in the traditional catheter, condom bag and sheathed designed catheter, respectively, which was strongly significant (P<0.001). Conclusion: The frequency of bacteriuria in the patients with designed sheathed catheter was significantly less than the traditional catheter. Therefore, using the designed catheter in short-term may be safer in the patients. Trial Registration: The trial was registered in the Thai Clinical Trials Registry (identifier: TCTR20200703002; http://www.clinicaltrials.in.th/index.php?tp=regtrials&menu=trialsear ch&smenu=fulltext&task=search&task2=view1&id=6443).
