Ultrasound-Guided Transperineal Prostate Biopsy

Patient looking at prostate biopsy results with doctor

Prostate cancer is one of the most commonly diagnosed malignancies in American men (second only to skin cancer). For this reason, many experts recommend an annual prostate cancer screening beginning at age 50 for men at average risk. The screening process may involve a blood test, a prostate-specific antigen (PSA) test and/or a digital rectal exam (DRE). If a man's PSA level is elevated or his DRE returns an abnormal result, the next step is usually a biopsy, which is the only way to confirm a diagnosis of prostate cancer.

The disadvantages of the traditional transrectal approach

Most prostate biopsies are performed transrectally. Although this approach can be effective and has been used for many years, it has two significant downsides. First, because the biopsy needle is passed through the potentially contaminated rectum, there is a heightened risk of sepsis, a life-threatening infection. Second, some areas of the prostate, including the anterior prostate, tend to be undersampled in a transrectal ultrasound-guided prostate biopsy, which increases the risk of missing the cancer and producing a false negative result.

The advantages of the new transperineal approach

A transperineal ultrasound-guided prostate biopsy is a safer and more accurate alternative to a transrectal ultrasound-guided prostate biopsy. Both procedures are performed with real-time imaging guidance; however, the main difference between the two is the placement of the biopsy needle. During a transperineal ultrasound-guided prostate biopsy, the needle is inserted through sterilized skin between the scrotum and rectum, then introduced into the prostate. Thus, the risk of sepsis is greatly reduced. Additionally, the transperineal approach allows for better access to the anterior prostate and therefore yields a more comprehensive tissue sample for analysis by a pathologist under a microscope.

Who is a good candidate for a transperineal ultrasound-guided prostate biopsy?

While a transperineal ultrasound-guided prostate biopsy is appropriate for all patients, it can be particularly beneficial for men who have or had:

  • A history of infection after a previous transrectal biopsy
  • Rectal bleeding complications after a previous transrectal biopsy
  • A suspected tumor in the anterior prostate and a previous negative transrectal biopsy
  • A history of prostatitis
  • Inflammatory bowel disease
