Abstract

This study aims to define the usefulness of antibiotic prophylaxis of urinary tract infection (UTI) in postmenopausal female undergoing invasive urodynamics (IU). Two hundred sixty-two postmenopausal females underwent IU. Before urodynamics, all females were double blindly randomized in two age stratified groups. Group 1 (130 patients) received oral antibiotic prophylaxis with a single 400-mg dose of norfloxacin. Group 2 (132 patients) received norfloxacin placebo. Statistical analysis was performed by a chi (2) test to evaluate differences between groups for UTI incidence rate. Fifty-four patients of 262 (20.6%) resulted affected by UTI [24 of 130 subjects who received antibiotic prophylaxis (18.4%) and 30 of 132 subjects who received placebo (22.7%)]. There was no statically significant difference (P = 0.242) regarding UTI incidence rate between patients who received and those who did not received antibiotic prophylaxis. UTI incidence rate in postmenopausal women undergoing urodynamics is not affected by administration of antibiotic prophylaxis at the desired level of efficacy.
