Description of intervention(s) / exposure
This project will compare transperineal prostate biopsy under local anaesthetic with Penthrox (intervention arm) versus general anaesthetic (control arm). The biopsy will take approximately 20-30 minutes and will be performed by a urologist.
Intervention arm:
- Local anaesthetic will be lignocaine (200 mg) diluted in saline via subcutaneous route 5 minutes prior to procedure
- Local anaesthetic will be administered by the urologist performing the biopsy
- Penthrox (active ingredient methoxyflurane, max dose 6ml) will be delivered via inhalation. Participants will inhale and exhale through the mouthpiece of a Penthrox inhaler attached to a carbon filter. They will be in instructed to inhale and exhale into the mouthpiece for 6-8 breaths, beginning inhalation 30 seconds prior to commencement of the procedure, after which they may inhale intermittently as required for the duration of the biopsy

Comparator / control treatment
The general anaesthetic is administered by the anaesthetist. Induction commences approximately 5 minutes prior, and emergence from anaesthesia approximately 5 minutes post completion of the biopsy procedure.
The comparator arm will comprise retrospective cohorts of patients who have undergone transperineal biopsies at the same health service prior, under general anaesthetic between August 2022 and August 2024, prior to prospective recruitment of the intervention arm of this study.

Summary
Brief summary
The aim of this study is to assess the tolerability, safety and cost of transperineal prostate biopsy techniques in men with suspected prostate cancer. Who is this for? You may be eligible to participate in this study if you are scheduled to undergo a transperineal prostate biopsy for suspected prostate cancer, or as part of active surveillance for prostate cancer. Study details Participants who consent to participating in this study will undergo a transperineal prostate biopsy with Penthrox and local anaesthetic by a qualified Urologist at a public hospital. We will assess your pain levels during the biopsy with a visual analogue scale survey and also analyse rates of cancer detection, perioperative complications and costs. We will do this by retrospectively comparing to cohorts of patients who have undergone transperineal biopsies at the same health service prior, under general anaesthetic. Our objective is to demonstrate that transperineal prostate biopsies under local anaesthetic are comfortable for the patients, safe, and just as accurate as those performed under general anaesthetic. Further, we aim to demonstrate that it is more efficient and cost effective, therefore resulting in reduced healthcare costs and improved accessibility with less wait times for patients requiring a prostate biopsy.
