Abstract
The efficacy of a short (Group I) and a prolonged (Group II) course with ciprofloxacin was assessed in patients undergoing transurethral prostatic resection for benign hyperplasia or cancer of the prostate and compared with that of controls without antibiotic (Group III). Both regiments significantly reduced the frequency of postoperative bacteriuria (p < 0.01) and of severe infectious complications (p=0.004) as compared to the controls. Both regimens were equally effective in preventing perioperative and postoperative acquisition of bacteriuria in patients without bacteriuria at surgery. In patients with bacteriuria before surgery, bacteriuria was found postoperatively in 35% in Group I and 10% in Group II (p=0.012), but in 82 % of the patients in Group III. Ciprofloxacin inhibited all but 7 of 176 bacterial strains at an MIC of ⩽ 1μg/ml. Given orally ciprofloxacin is a valuable alternative antimicrobial for use in conjunction with transurethral prostatic resection. A short course is sufficient for prophylaxis, and adequate therapy is achieved with a prolonged regimen.
