Background: There has been a great deal of discussion regarding the necessity of antibiotic prophylaxis in transurethral cystoscopy. In order to clarify this complicated issue, a randomized prospective study was performed on 126 patients planned for cystoscopy.
Patients and methods: 126 patients who underwent urethrocystoscopy and did not have pyuria and bacteriuria were included and divided randomly into 2 groups: group 1 received 400 mg of norfloxacine and group 2 nothing. Urinalysis were performed on all patients 3 days after the examination. Statistical analyses were performed using Chi 2 test and the level of significance was set at 5%.
Results: The global rate of infection was 5%. In the group 1 the incidence of infection was 3% (2/67) vs 5.1% (5/59) in group 2. There were no significant differences in the incidence in the background factor between the 2 groups of patients (p > 0.05).
Conclusion: Prophylactic administration of antibiotic before cystoscopy does not decrease the incidence of urinary tract incidence and it is not necessarily in patients with sterile urine.
