ABSTRACT
ABSTRACT Introduction: We aimed to evaluate the efficacy of the duration of prophylactic antibiotic administration in patients undergoing transrectal ultrasound (TRUS) guided biopsy. Material and Methods: A total of 367 patients undergoing a prostate biopsy between September 2007 and June 2009 was reviewed retrospectively and divided into 2 groups according to prophilaxy: oral ciprofloxacin (750 mg every 12 hours) for 3 or more days in Group-1 and single day in Group-2. Demographic characteristics of patients, symptoms, PSA values, IPSS scores, prostate sizes, pathologic results and complications were compared between the groups. Results: The mean age of all patients was 63.92 years and the mean PSA was 13.61ng/ dL. The pre-biopsy mean IPSS score was 12.47 and mean prostate volume 52.53 mL. For 78.2% of patients the current biopsy was their first biopsy. Cancer detection rate was 24.2%. Fever was observed in 3 (1.2%) patients in Group-1 and 5 (4.0%) patients in Group-2. Local infections occurred in 2 (0.8%) and 1 (0.8%) patients respectively in Groups 1 and 2. Acute prostatitis was observed in only 1 (0.8%) patient in Group-2. Accepted after revision: None of the patients developed septicemia or other serious infection. There was no statistically significant difference in terms of fever, local infections (epididimitis, orchitis, etc.) and acute prostatitis. Conclusions: In a selected patient population single dose prophylaxis with ciprofloxacin can be safely administered compared to other regimens of 3 or more days. Increasing the duration of antibiotic prophylaxis does not decrease infectious complications.
