Abstract
Background: We present our series of free-hand transperineal prostate biopsy (fTP-Bx) using a novel coaxial needle introducer guide. All cases were performed in the office under local anesthesia (LA) without sedation. The majority received no prophylactic antibiotics. Materials and Methods: We retrospectively reviewed the electronic medical records of 242 consecutive fTP-Bx cases using the PrecisionPoint™ Transperineal Access System (PPTAS) performed under LA without sedation by a single urologist (R.J.S.) at Kaiser Permanente Southern California. We compared complication rates of this series of cases to our initial series of 62 fTP-Bx cases without the PrecisionPoint as well as 133 transrectal prostate biopsy cases performed before we adopted the transperineal approach. Results: Of the 242 consecutive free-hand transperineal biopsies performed between August 26, 2016 and December 31, 2018, 212 (88%) received no antibiotic prophylaxis. Medians for age, prostate-specific antigen, prostate volume, prostate-specific antigen density, and cores sampled were 63 years, 7.2 ng/mL, 50 mL, 0.15 ng/mL/cc, and 20 cores, respectively. Detection rates of overall and clinically significant prostate cancer averaged 43.4% (105/242) and 14% (35/242), respectively. Average visual analog scale pain rating was 3.9 and average procedure time was 20 minutes. Complication rates of sepsis, acute urinary retention, clot retention, and perianal abscess were 0.0% (0/242), 0.4% (1/242), 1.2% (3/242) and 0.4% (1/242), respectively. Conclusions: This series of office-based free-hand transperineal biopsy under LA without sedation performed with the PPTAS contains a large number of cases in which prophylactic antibiotics were not administered, yet there were no complications of postbiopsy sepsis. However, there was one case of a delayed perianal abscess. fTP-Bx under LA enables the easy integration of transperineal biopsy into a normal outpatient clinic workflow.
