ABSTRACT
We conducted a double-blind, placebo-controlled randomized trial to assess the effect of single-dose prophylaxis using co-trimoxazole (960 mg) (n = 46) or ciprofloxacin (500 mg) (n = 43) vs. placebo (n = 51) before urinary catheter removal on significant bacteriuria (SBU) (primary outcome) and urinary tract infection (UTI) in surgical patients with scheduled bladder drainage for 3-14 days. SBU was determined directly after catheter removal, and UTI 12-14 days after catheter removal. After 12-14 days, incidences of SBU were 19%, 19% and 33% for patients receiving ciprofloxacin, co-trimoxazole and placebo, respectively (p ns), and incidences of UTI were 3%, 0% and 3% for patients receiving ciprofloxacin, co-trimoxazole and placebo, respectively (p ns).
