Aim: to evaluate the effect of a 3-day course antibiotic post-urodynamic study (UDS) to prevent urinary tract infection (UTI). Methods: this was a randomized double blind clinical trial on the proportion of UTI in patients who received levofloxacin 500 mg once a day for 3 days after UDS compared to nontreated patients. The outcome of this study was the incidence of lower UTI in levofloxacin group and placebo group. Lower UTI was defined as patient with one or more clinical symptoms of lower UTI and one or more urinalysis parameter of UTI. Chi-square was used to evaluate the association between the lower UTI and treatment group. Results: a total of 126 patients were enrolled in this study from two outpatient urology clinics in Jakarta: Cipto Mangunkusumo Hospital and Asri Hospital. Overall, 26 patients (20.6%) had UTI post UDS (8 out of 63 patients from levofloxacin arm (12.7%) and 18 out of 63 patients from placebo arm (28.6%); p=0.028). The most common isolate found was E. coli (n=18 patients; 69.2%). The most common indications to perform UDS were Lower Urinary Tract Symptoms (LUTS) with failure of therapy (n=43 patients; 25%), LUTS after invasive treatment (n=29 patients; 16.9%), and overactive bladder with failure of therapy (n=22 patients; 12.7%). Conclusion: the use of antibiotic post-UDS can prevent incidence of lower UTI.
