Developments in optimizing transperineal prostate biopsy.

Curr Opin Urol 2022 01;32(1):85-90

Department of Urology, NewYork Presbyterian Hospital/Weil Cornell Medicine, New York, New York, USA.

Purpose Of Review: Prostate biopsy is a very commonly performed office procedure leading to the diagnosis of the most prevalent solid-organ malignancy in American men. Although the transrectal technique for prostate biopsy remains the gold standard, there is increasing interest in the transperineal approach as it offers a clean, percutaneous approach that significantly decreases the risk for infection. In this review, we discuss emerging developments in transperineal prostate biopsy that may optimize the way biopsies are performed in clinical practice. Read More

Anaesthesia in PROstate Biopsy Pain Obstruction Study: A Study Protocol for a Multicentre Randomised Controlled Study Evaluating the Efficacy of Perineal Nerve Block in Controlling Pain in Patients Undergoing Transperineal Prostate Biopsy.

Front Surg 2021 6;8:649822. Epub 2021 Oct 6.

Department of Urology, Shanghai East Hospital, School of Medicine, Tongji University, Shanghai, China.

Transperineal prostate biopsy is as effective as the transrectal biopsy in detecting prostate cancer and has a lower risk of infection. However, concerning the procedural pain of the transperineal route, a higher level of anaesthesia is needed, which prevents this approach from being widely used. Although several methods of local anaesthesia to relieve pain during transperineal biopsy have been described, few well-designed trials have been conducted to assess the efficacy of local anaesthesia.

Economic Evaluation of Transperineal versus Transrectal Devices for Local Anaesthetic Prostate Biopsies.

Pharmacoecon Open 2021 Dec 9;5(4):737-753. Epub 2021 Jul 9.

Cambridge Urology Translational Research and Clinical Trials Office, Cambridge Biomedical Campus, Cambridge, UK.

Background: Biopsy of the prostate for suspected cancer is usually performed transrectally under local anaesthesia in the outpatient clinic setting. As this involves piercing the bowel wall, the procedure is associated with a risk of infection. Recently, devices that facilitate transperineal biopsy approaches have been developed that avoid piercing the bowel and so should reduce the risk of infection. Read More
