Abstract
We investigated the efficacy of prophylactic use of single dose oral ofloxacin and trimethoprim-sulfamethoxazole regimens for transrectal prostate biopsy in 110 men. In the ofloxacin, trimethoprim-sulfamethoxazole and control groups, urinary infection was found in 2 (4.76%), 3 (6.66%) and 6 (26.08%) patients, respectively. Both of these antibiotic regimens produced a statistically significant reduction in urinary infection (p<0.02, p<0.05). Our study indicates that single dose fluoroquinolone or trimethoprimsulfamethoxazole prophylaxis seems to be effective, practical and economical.
