Pain-Free TRUS B
A prostate biopsy involves taking small pieces of the prostate through a needle so that it can be looked at with a microscope. A TransRectal UltraSound (TRUS) guided biopsy is the usual way of performing a biopsy and involves inserting a thin needle through the wall of the rectum into the prostate using the guidance of an ultrasound probe. An injection of a local anaesthetic (lignocaine) around the prostate is the standard way of reducing the discomfort of a prostate biopsy. Methoxyflurane (Penthrox®) is a drug given with a simple inhaler and is widely used by first aid services to reduce pain. This randomised trial will determine if the discomfort of prostate biopsies can be reduced by giving people inhaled methoxyflurane in addition to their standard injections of local anaesthetic. This study will include 420 people and is being conducted by ANZUP Cancer Trials Group in collaboration with the NHMRC Clinical Trials Centre, University of Sydney.
If you think this trial might be right for you, please ask your doctor.
