To determine the efficacy and safety of single-dose oral ciprofloxacin prophylaxis for the
prevention of post-operative bacteriuria following transurethral resection of the prostate or
bladder tumour, a prospective, randomized, double-blind, placebo-controlled trial was conducted.
Five hundred and eighteen patients were randomized in a 2:2:1 ratio to receive ciprofloxacin 500
mg, cefotaxime 1 g or placebo 30- 90 min before surgery. Of the 368 efficacy-evaluable patients,
five (3.3%) ciprofloxacin, seven (4.8%) cefotaxime and five (7.0%) placebo recipients had post-
operative bacteriuria (
10
4 cfu/mL) during post-operative days 2- 15. Five (3.4%) ciprofloxacin, five (3.4%)
cefotaxime and one (2.4%) placebo recipients were considered clinical failures, of whom one,
two and one patients, respectively, had concomitant bacteriuria. Drug-related adverse events
were reported in six of 204 (3%) ciprofloxacin, 12 of 197 (6%) cefotaxime and one of 101 (1%)
placebo patients. The observed rates of post-operative bacteriuria suggest that a single 500 mg
dose of ciprofloxacin is suitable prophylaxis for transurethral surgery.
