Transrectal ultrasound (TRUS) and prostate biopsies
Prostate biopsies are taken under ultrasound guidance and sent to a histology laboratory for examination under a microscope. These are taken via the rectum and local anaesthetic is used. The tissue is examined for evidence of cancer, infection and/or inflammation.
Template Guided Biopsies
Prostate biopsies are taken through the perineum using a template to guide the position of the samples taken. This is done under general anaesthetic. The samples are then sent to a histology laboratory for examination under a microscope. The tissue is examined for evidence of cancer, infection and/or inflammation. The benefits of prostate mapping over TRUS and standard biopsy are a reduced rate of missing the cancer, a reduced rate of infection, and bleeding also tends to be minimal. Prostate mapping is always done in conjunction with MRI imaging.
The results of all of the above tests take between three days and two weeks to be ready and will be explained to you once they are available.
If prostate cancer is diagnosed, a bone scan is sometimes needed to check for metastases (spread of cancer to the bones) but your urologist will discuss this with you.
