Abstract

OBJECTIVES:

To determine the efficacy of prophylactic ciprofloxacin in preventing urinary tract infections caused by urodynamic study (UDS).

METHODS:

A total of 210 patients presenting for UDS during a 16-month period were offered enrollment in the study. A clean-catch midstream urine sample was taken 24 hours before and 48 to 72 hours after the procedure and after microscopic examination and culture were done. All patients underwent a standard UDS. The 192 patients who had sterile urine before intervention were included in the study. Randomly, 98 of the 192 patients were orally given 500 mg of ciprofloxacin 1 hour before the urodynamic intervention and 94 were not given anything. The patients who were found to have significant bacteriuria after UDS were followed up and treated properly.

RESULTS:

Eighteen patients (8.6%) who had significant bacteriuria in the urine culture before UDS were excluded from the study. The rate of significant bacteriuria in the urine culture after UDS was 7.3% overall, 1% in the prophylaxis group, and 14% in the controls, a significant difference (P = 0.002). The most common uropathogen was Escherichia coli (57%). Three independent risk factors were identified: not giving antibiotic prophylaxis before UDS; antibiotic use in the preceding month; and the presence of pyuria before UDS.

CONCLUSIONS:

Urinary tract infections after UDS decreased from 14% to 1% with a single dose of ciprofloxacin 500 mg orally before UDS. We recommend antibiotic prophylaxis for patients undergoing a UDS.
