Brief summary

Urodynamic Study (UDS) represents a series of agreed-upon clinical tests and is used to evaluate the functional status of the lower urinary tract, providing a pathophysiological basis for urinary symptoms. Urodynamic Study involves catheterization of the lower urinary tract. The prevalence of urinary tract infection after UDS ranges from 1,5% to 30 %. Studies of prophylactic antibiotics for UDSs have offered data of contradictory and limited predictive values. Some investigators concluded that prophylactic antibiotics were valuable and others have not. The objective of this study is to evaluate the efficacy of antibiotic prophylaxis before UDS in women, using different antibiotic regimens.

Detailed description

This study is randomized, double blind study was carried out in the Department of Gynecology at Sao Paulo Federal University from January 2009 to December 2012. The patients were randomized in four groups: Group A received 500mg of levofloxacin, group B received placebo, group C received 80mg trimethoprim and 400mg sulfamethoxazole (SMZ-TMP) and group D received 100mg of nitrofurantoin. The tablets were administered 30 minutes before de UDS. All patients were instructed to collect midstream urine sample to the microbiology laboratory 14 days after the UDS. Significant bacteriuria was considered when \>1.000.000 organisms/mL of a single species was isolated. All data were entered into Statistical Package for Social Sciences (SPSS) 16.0 for statistical analysis and graphic representation. Likelihood -ratio test and Fisher's exact test were used to compare the prevalence of significant bacteriuria after UDS in the different groups and Student's t-test and ANOVA test were used to compare continuous variables. To compare the groups regarding the BMI variable and parity, the model analysis of variance (ANOVA) was used, or if necessary, the nonparametric Kruskal-Wallis test and to compare the groups in relation to menopause variable, we used the Chi-square test. A significance level of 0.05 was established for statistical analysis.
