INTRODUCTION

MRI fusion transperineal prostate biopsy (MRI fusion TPB) is a technique that is used to accurately and comprehensively sample the prostate for cell changes that may be related to cancer or other conditions affecting the prostate gland. Biopsy is the only way to conclusively diagnose prostate cancer.

Who is suitable for an MRI fusion transperineal prostate biopsy?

MRI fusion TPB is indicated for patients that:

  • Have a nodule or other abnormality of the prostate, that has been detected during a digital rectal examination (DRE)
  • Have enlargement of the prostate
  • Have elevated levels of prostate-specific antigen (PSA) on their blood test
  • Have an elevated PSA level, but an ultrasound-guided biopsy has come up negative for prostate cancer
  • Have been diagnosed with prostate cancer previously, as part of their ongoing monitoring

What are the advantages of the MRI fusion transperineal prostate biopsy?

  • Allows for the collection of a large number of samples efficiently and accurately
  • Enables the entire prostate gland to be sampled to visualize cell changes:
    • Allows for the diagnosis of prostate cancer
    • In cases where prostate cancer has been diagnosed, allows to check for any changes
  • Can be used to diagnose other conditions of the prostate such as:
    • Enlargement of the prostate (BPH)
    • Inflammation of the prostate, often caused by infection
    • Changes in prostate cell type, that is not cancer (PIN)
  • No rectal bleeding
  • Significantly less risk of infection compared with transrectal (via the rectum) biopsies.

How is an MRI fusion transperineal prostate biopsy performed?

  • Before the biopsy procedure can take place, the patient will have previously had an MRI scan of the prostate
  • The procedure is usually performed under general anaesthetic, and takes around 30-60 minutes to complete
  • An ultrasound probe is inserted via the rectum, and using specialised technology, the live ultrasound image is fused with the existing MRI image
  • A special biopsy grid with holes 5mm apart is positioned against the skin behind the testicles (the perineum)
  • This allows the surgeon to collect biopsies from very specific areas of interest in the prostate.

What to expect after an MRI fusion transperineal prostate biopsy?

  • You will be able to go home on the same day following your procedure
  • You may have some light bleeding in the perineal area, which is easily managed with gentle pressure
  • You may feel some discomfort in the area for a day or two following the procedure
  • Some patients notice a small amount of blood in their urine or ejaculate in the days following the procedure, but this usually goes away within a week or so
  • Very rarely, the temporary inability to pass urine (urine retention) occurs; this can be fixed by temporary placement of a urinary catheter.

Procedure outcomes of MRI Fusion Prostate Biopsy

The recovery time is very brief and within a couple of days normal activities can be resumed. The samples are examined by a pathologist, and the results are usually available for review by your urologist within a few days. MRI fusion prostate biopsy helps to accurately diagnose and distinguish between cancer and other conditions of the prostate. If required, appropriate treatment can then be initiated.
