To Determine Association and Assessment between Urinary Tract Infection and Urodynamic Examination Based on Urinalysis Results

Aim: To determine risk factors for urinary tract infection (UTI) after urodynamic examination by evaluating patients' clinical characteristics and urodynamic parameters. Methods: Two hundred and sixty-one female patients (mean age 58.7±12.3 yrs) from May to December 2011 visited tertiary care hospital who had lower urinary tract symptoms or needed definite diagnosis before pelvic floor reconstruction or anti-incontinence surgery received urodynamic examination. All patients received urinalysis on the scheduled day of urodynamic examination and 3 days after urodynamic examination. Results: Among 261 patients, 19 and 51 patients had UTI before and after urodynamic examination, respectively. Our data suggest that urodynamic examination causes significantly increased incidence of UTI. Increased number of vaginal births, UTI before investigation, diabetes and decreased average flow rate are risk factors for UTI after urodynamic examination. Conclusion: When the prevalence of UTI after urodynamic examination is higher than 10%, we recommend that prophylactic antibiotics should be given for high-risk patients with parameters like D/M,old age and multi para(>3).
