Prostate biopsies are performed when the results of routine tests like a rectal exam or PSA (prostate-specific antigen) blood test yields abnormal results, indicating a potentially serious prostate problem. Knowing what to expect during the biopsy can help make the procedure less stressful.
Prostate Biopsy Methods
The most common method is transrectal, which accesses your prostate through your rectum. There is also the perineal method (which goes through the skin between your rectum and scrotum) and the transurethral method (which enters through your urethra).
Preparing for the Procedure
Five to seven days before your biopsy, discontinue taking any medications that affect blood clotting (such as NSAIDS like ibuprofen, aspirin or Coumadin). The day of the procedure you will need to give yourself an enema and take antibiotics.
What to Expect During the Biopsy
You will be asked to lie on your left side and bend your knees. Your doctor will guide an ultrasound probe into your rectum to visualize the prostate and then use a needle to retrieve tissue samples for microscopic examination.
What To Expect After the Biopsy
The procedure usually takes between 20 and 30 minutes, after which you will be able to resume your normal activities. You might feel the sensation of needing to have a bowel movement or urinate, which will pass after several hours.
Recovery
Expect to see some blood in your ejaculate, stool or urine for several days after the procedure. You may be tender at the site of the biopsy. Your doctor will recommend a pain reliever and you will likely need to take a short course of antibiotics.
