Prostate Biopsy: Fusion Transrectal Ultrasound Guided
A prostate gland biopsy is a procedure to obtain small samples of prostate tissue to be examined under a microscope. This is done using MRI imaging obtained prior to the biopsy to detect abnormal areas to target.
During a transrectal prostate biopsy, a thin needle is inserted guided by transrectal ultrasound and superimposed on the MRI images with computer software to identify
the exact target areas. Twelve to twenty four cores of tissue are taken and are sent to a pathologist to be examined under a microscope. The pathologist performs special staining and processing of the tissue cores to specifically detect cancer cells.
Results are available within two weeks.
If cancer cells are present, a grade called a Gleason score is given. The Gleason score is a tool used by the pathologist for predicting how aggressive the cancer is.
Tell your doctor if:
Before your prostate biopsy, you will be requested to take antibiotics. The instructions and prescriptions will be given when the biopsy is scheduled. It is important that you fill the prescription and take the antibiotics exactly as prescribed. This will decrease the risk of infection significantly.
How it feels:
For a transrectal biopsy, you may feel pressure in the rectum while the ultrasound probe is guided in place. You also may feel a brief, sharp pain as the biopsy needle is quickly inserted into the prostate gland. Remember, it lasts just a few minutes and done with a prostate block. A patient may also use ProNox during the procedure for extra comfort and relaxation.
Following the biopsy, you will be asked to avoid strenuous activities for about 24 hours. You may experience mild discomfort in the perineal area and a little blood in your urine
for a few days. You may also have some discoloration of your semen for one month or longer after the biopsy. It is also common to experience a small amount of bleeding from your rectum for 2 to 3 days after the biopsy.
After the biopsy call your doctor immediately if you:
