Prostate Biopsy in Bend, OR

What is transperineal prostate biopsy?

Transperineal biopsy is performed to evaluate prostate cancer by carefully placing a needle through the skin between the scrotum and rectum to receive a tissue sample.

Why this procedure is performed?

This biopsy procedure is performed to help detect prostate cancer. Dr. Neeb or Dr. Johnson-Mitchell will use an ultrasound to guide the biopsy to make sure the procedure is accurate and safe. A transrectal biopsy has been the standard method, but the transperineal approach is emerging as a superior alternative. One of the most significant drawbacks of a transrectal biopsy is the increased risk of infection. Since the biopsy needle passes through the rectal wall, there is a chance of introducing bacteria into the prostate, leading to infections such as sepsis. Now, the transperineal biopsy avoids the rectal wall entirely, significantly reducing infection rates.

Benefits of a Transperineal Prostate Biopsy

There are several benefits to a transperineal prostate biopsy, including:

  • Reduced risk of infection compared to transrectal biopsy
  • More accurate sampling since there is increased access to all areas of the prostate
  • Less discomfort
  • Lower risk of complications, such as rectal bleeding
  • Improved cancer detection rate

Who needs a transperineal prostate biopsy?

With the risk of prostate cancer, it is important to know how often you should get tested or have a prostate biopsy performed. Often, Dr. Neeb or Dr. Johnson-Mitchell  will test your PSA levels, which is a prostate-specific antigen first. From there, you may need a biopsy for further information. You may need a transperineal prostate biopsy if you:
  • Have abnormal PSA levels
  • Your PSA levels are rising
  • If you’ve had an inconclusive or negative biopsy
  • If you are at high risk for prostate cancer
  • If you’re monitoring prostate cancer risk or progression
  • If you are at increased risk due to family history

How the Procedure Works

If you are preparing for a transperineal prostate biopsy, you will discuss the procedure with Dr. Neeb or Dr. Johnson-Mitchell.

There are options for anesthesia, as the procedure is typically performed under local anesthesia. Some cases may require general anesthesia. To prepare for this, you may need to stop certain medications before the procedure or start taking antibiotics to reduce risk of infection.

When you are ready for the procedure, you will be on your pack and using ultrasound guidance, the urologist inserts a biopsy needle through the perineum to collect tissue samples. This allows for greater precision.

There may be a need to take multiple tissue samples through the perineum. This is the skin between scrotum and anus. This is a short procedure, lasting anywhere from 10 to 30 minutes.

Preparing for a Transperineal Prostate Biopsy

As you prepare for this procedure, Dr. Neeb or Dr. Johnson-Mitchell may recommend:
  • Stopping certain medications such as blood thinners
  • Antibiotics before the procedure at the chance of infection
  • An enema to clear the bowels before the procedure
  • Fasting if Dr. Neeb or Dr. Johnson-Mitchell  suggested general anesthesia

Recovery & Aftercare

You may experience mild discomfort, slight bleeding in the urine or semen, and trouble urinating. Most individuals can resume normal activities within a day or two.

Biopsy results are typically available within a few days to a week. If cancer is detected, further treatment options will be discussed with Dr. Neeb or Dr. Johnson-Mitchell. Contact Dr. Neeb or Dr. Johnson-Mitchell if you have a fever, abnormal bleeding, or feel any unusual side effects.

Risks & Potential Complications

There are significantly lower risks with a transperineal prostate biopsy.

Complications are rare but possible. You may experience minimal bleeding or possible infection. Talk to Dr. Neeb or Dr. Johnson-Mitchell if you are worried about any issues following the procedure.
