Transperineal Prostate Biopsy with MRI/Ultrasound Fusion Guidance

What is a Transperineal Prostate Biopsy with MRI/Ultrasound Fusion Guidance?

A Transperineal prostate biopsy is a procedure where tissue samples are taken from the prostate gland through the perineum (the area between the scrotum and anus) using a combination of MRI and ultrasound imaging for precise guidance. This method allows for more accurate targeting of suspicious areas in the prostate.

How is it Done?

  1. Pre-Procedure:
  • You may be asked to stop certain medications, such as blood thinners, a few days before the procedure.
  • A cleansing enema is recommended to clear the rectum.
  • Antibiotics are given on the day of the procedure to prevent infection.
  1. Procedure:
  • Local or general anesthesia is administered to minimize discomfort. Currently the MRI/US fusion technology is available only in the operating room at the hospital
  • After sedation, you will be positioned on your back with your legs elevated and the perineal area is cleansed.
  • An MRI scan of your prostate is used to create a detailed map and mark the suspicious areas.
  • An Ultrasound probe that is placed in the rectum is used during the procedure to then create a live image of the prostate.
  • Finally a fusion of the MRI and the Ultrasound images is done which allows a precise guidance of the biopsy needle.
  • The doctor uses the MRI images fused with real-time ultrasound to guide the needle through the perineum to the targeted areas in the prostate.
  • At least 13 samples are taken for analysis.

What to Expect Afterwards?

  • Immediately After: Some discomfort and minor bleeding from the perineum or in urine and stool (if you have hemorrhoids) are common.
  • Recovery:
  • Rest and avoid strenuous activity for 24-48 hours.
  • Drink plenty of fluids to help flush out the urinary system.
  • Monitor for signs of infection, such as fever or excessive pain and bleeding.
  • Biopsy results usually are back at about 3-10 days, so please make sure to have a follow up appointment to discuss the biopsy results. It is very important that you follow up.

Risks and Benefits

  • Benefits:
  • More accurate detection of prostate cancer.
  • Reduced risk of infection compared to the transrectal approach.
  • Better sampling of the prostate, especially in the anterior (deeper) and apical regions.

  • Risks:
  • Infection, despite preventive antibiotics.
  • Bleeding or hematoma (bruising) formation in the perineum.
  • Urinary retention or difficulty urinating.
  • Discomfort or pain at the biopsy site.
  • Painful or bleeding hemorrhoids
