Introduction: Interest in the use of transperineal prostate biopsy due to decreased infection risk has prompted increased research in the field. Several techniques exist, but the ultrasound guided freehand tranperineal prostate biopsy (FTPB) has demonstrated both saftey and versatility. The current study presents the safety, feasibility and outcomes of FTPB.
Methods: Retrospective review of patients between January 1, 2012 and April 30, 2018 who underwent FTPB procedures in the abscence of urinary tract infection. Several variables were compared between Cohorts of patients who did and did not receive periprocedural antibiotics. Continuous variables were compared using 2-tailed student t-tests and categorical variables using the chi-square test of independence; both at a significance level of 0.05. Patient, procedural and outcome data were recorded and assessed (table 1), including complications and/or infections.
Results: A total of 1223 patients underwent FTPB, 948 with antibiotics and 275 without. All procedures were performed by 3 urologists at a single outpatient office or surgical center setting. Groups significantly differed with the no antibiotic group being older and having more biopsy cores obtained on average. No complications, Clavien grade â‰¥2, occurred.
Conclusions: FTPB, for suspicion or AS of PCa, without perioperative antibiotics is feasible, effective and safe. Further studies to evaluate long-term effectiveness are recommended.
