Sepsis rates after template prostate biopsy with single-dose prophylactic antibiotic

INTRODUCTION: Urosepsis is a significant risk associated with prostate biopsy. Resistance of microorganisms to antibiotics is a challenging issue for clinicians in everyday practice. In the current study, we investigated the rates of sepsis and hospital admissions following transperineal (TP) prostate biopsies using a single dose of gentamicin. MATERIAL AND METHODS: Data for consecutive patients who underwent TP prostate biopsies (March 2019–March 2020) were included. Patients received a single-dose of prophylactic gentamicin 120 mg IV and had skin preparation with antiseptic povidone-iodine or chlorhexidine solution prior to the procedure. Patient’s electronic records were reviewed for rates of sepsis and readmission to hospital within 7 days following TP prostate biopsy. RESULTS: A total of 365 consecutive patients were included in the study. After exclusion of non-eligible patients, 280 patients were included in final analysis. The median age was 67 years (32–83), the median prostate-specific antigen (PSA) level was 8.5 ng/ml (0.2–58), and the median prostate size was 44 cc (10–188). Approximately 58% of patients had one or more comorbidities in the form of diabetes mellitus (DM), hypertension, asthma, chronic kidney disease, or ischemic heart disease. Adenocarcinoma was found in 71.7% of patients. None of the 280 patients developed sepsis. Urinary tract infection (UTI) occurred in 2.8% of patients with E.coli, none of them required hospital readmission. CONCLUSIONS: Our single centre experience showed a 0% sepsis rate after TP prostate biopsy with single prophylactic dose of gentamicin. Future randomized controlled trials (RCTs) should explore the possibility of performing these procedures without antibiotic prophylaxis in order to reduce the unnecessary use of antibiotics.
