Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.
Input: The aim of this study was to evaluate the effect of povidone-iodine rectal disinfection and targeted antimicrobial prophylaxis in men undergoing transrectal ultrasound-guided prostate biopsy based on rectal swab culture results.', 'From January 2011 to December 2015, we studied differences in infectious complications in men who received povidone-iodine rectal disinfection with targeted antimicrobial prophylaxis and those who received empirical prophylaxis before transrectal ultrasound-guided prostate biopsy. Clinical variables including demographics, prior antibiotic, rectal swab culture results, povidone-iodine rectal cleansing, antibiotic prophylaxis, and infectious complications were evaluated. Patients were divided into three groups as follows: Group A received no povidone-iodine rectal cleansing but received empirical antimicrobial prophylaxis; group B received povidone-iodine rectal cleansing and empirical antimicrobial prophylaxis; and group C received povidone-iodine rectal cleansing and targeted antimicrobial prophylaxis.', 'Patients were divided into group A (n=192; 13.2%), group B (n=579; 39.9%), or group C (n=679; 46.8%). In groups A and B, all patients received fluoroquinolone antimicrobial prophylaxis. Group C patients received targeted antimicrobial prophylaxis according to antibiotic resistance of rectal flora, and 71.1% of these received fluoroquinolone antimicrobial prophylaxis. Infectious complication rates were 3.6, 2.9, and 1.3% in group A, group B, and group C, respectively. Incidences of acute prostatitis and bacteremia were significantly lower in group C (p=0.041 and p=0.049, respectively) than in the other groups.
Output:
Are povidone-iodine rectal cleansing and targeted antimicrobial prophylaxis using rectal swab cultures in men undergoing transrectal ultrasound-guided prostate biopsy associated with reduced incidence of postoperative infectious complications?
