A multi-center, controlled, randomized, open-label clinical study of levofloxacin for preventing infection during the perioperative period of ultrasound-guided transrectal prostate biopsy

By comparing the safety and efficacy of 500 mg of oral levofloxacin for 3 days with those of intravenous antibiotics for 3 days in the prevention of infectious complications of ultrasound-guided transrectal prostate biopsy (TPB), we provided a safe and cost-effective infection preventive protocol for TPB in China. A total of 801 patients with indications for TPB in 12 centers were randomized into two groups from October 2011 to December 2015. Patients in the test group (n = 392) took 500 mg of oral levofloxacin for 3 days. Patients in the control group (n = 409) underwent intravenous antibiotics according to the traditional habits of the center for 3 days. All patients underwent ultrasound-guided TPB. Infectious complications were compared between the two groups. Different kinds of antibiotic were used in the control group. Comparing the two groups, the mean patient age was 70.6 ± 14.0 and 70.5 ± 14.0 years. The incidence of total infectious complications was 4.6 % (18/392) and 4.4 % (18/409) respectively, the incidence of asymptomatic bacteriuria was 3.1 % (12/392) and 2.7 % (11/409), the incidence of symptomatic urinary tract infection was 0.0 % and 0.2 % (1/409), the incidence of fever was 0.8 % (3/392) and 0.5 % (2/409), the incidence of bacteremia was 0.5 % (2/392) and 0.0 %, and the incidence of urosepsis was 0.3 % (1/392) and 1.0 % (4/409) respectively (all P > 0.05). The selection of antibacterial agents for TPB is in ca haotic condition in China. Oral levofloxacin at 500 mg once daily for 3 days is a safe, convenient, and cost-effective infection preventive protocol for TPB in China.
