Prospective non-randomized study on the use of antibiotic prophylaxis with ciprofloxacin in flexible...

The goal of this study is to analyze whether there is a need for antibiotic prophylaxis in this outpatient procedure.

Prospective observational non-randomized study including 100 patients divided into two groups: - Group 1: 48 patients receiving 500 mg of ciprofloxacin prophylaxis 1 hour before urethrocystoscopy; - Group 2: 52 patients without antibiotic prophylaxis. Before inclusion of the patients in the study, we checked the absence of urinary tract infection by means of a urinalysis obtained 3 days before the procedure. We analyze: cystoscopy indication, cystoscopy results, presence of comorbidities, urinalysis 7 days after the procedure, and urinary symptoms within 7 days of the procedure. The statistical analysis was performed using SPSS 20.0 and the statistical significance was p=0.05.

The average age of patients in group 1 was 66.7±12.4 versus 65.6±10.8 years in group 2 (p=0.6). There are no differences in the percentage of men/women included in the groups. 14% of patients of group 1 and 12% of group 2 presented bacteriuria, without showing any significant differences. In the multivariate study, it is observed that neither age, nor diabetes, smoking, lower urinary tract symptoms, nor immunosuppression are related with the onset of bacteriuria in the groups.

We do not consider the use of ciprofloxacin as prophylaxis for flexible cystoscopy is appropriate in this area of health, since it does not reduce the presence of urinary infection or bacteriuria.
