Comparison of the effectiveness of single-dose levofloxacin with single-dose fosfomycin pre-urodynamic study related to the incidence of urinary tract infection: a randomized controlled trial
Abstract
PURPOSE: The purpose of this study is to examine the efficacy of 500 mg levofloxacin and 3 g fosfomycin given as single-dose prophylactic antibiotics one hour before urodynamic studies (UDS) to prevent urinary tract infections (UTIs). METHODS: This single-blinded, randomized clinical trial included 126 patients who underwent UDS between December 2022 and March 2024 at two urology centers in Jakarta. The patients, aged 18 years and older, were randomized equally into two groups receiving either 500 mg levofloxacin or 3 g fosfomycin prior to UDS. The primary indications for UDS included lower urinary tract symptoms (LUTS) (54.8%), overactive bladder (OAB) (32.8%), underactive bladder (8.9%), and stress urinary incontinence (3.5%). Three days post-UDS, patients were followed up with urinalysis and clinical assessment for UTI symptoms. RESULTS: Among the 126 patients, UTI was diagnosed in 26 cases (20.9%), with 14 cases (22.2%) in the levofloxacin group and 12 cases (19%) in the fosfomycin group, showing no significant difference (p = 0.660). Symptomatic UTIs occurred in 6 patients (4.8%) in the levofloxacin group and 7 patients (5.6%) in the fosfomycin group. E. coli was the most commonly detected bacterium in urine cultures. CONCLUSION: In our center, there was no significant difference in the clinical outcome between the administration of 3 g fosfomycin and 500 mg levofloxacin as single-dose prophylactic antibiotics prior to UDS. Given the rising antibiotic resistance,…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 126 participants or records.
