How It Is Done continued...
Your skin at the biopsy site is cleaned with an antiseptic solution, and the area around it is covered with sterile cloth. Your doctor will wear sterile gloves. It is very important that you do not touch this sterile area.
Transrectal ultrasound (TRUS) is generally used to guide the needle to the correct biopsy location.
A small cut (incision) is made in your perineum. Your doctor inserts a finger into the rectum to hold the prostate gland and then inserts the needle through the incision and into the prostate gland. To collect a sample of tissue, the needle is gently turned and then pulled out. Biopsy samples may be taken from several areas of the prostate. Pressure is applied to stop the bleeding, and a small bandage is placed over the cut. The biopsy usually takes about 15 to 30 minutes.
How It Feels
You may feel a slight sting when you receive an injection of medicine to numb your skin. You may feel a dull pressure as the biopsy needle is inserted. For a transrectal biopsy, you may feel pressure in the rectum while the ultrasound probe or guiding finger is in place. You also may feel a brief, sharp pain as the biopsy needle is inserted into the prostate gland. Usually several biopsy samples are collected.
Following the biopsy, you will be asked to avoid strenuous activities for about 4 hours. You may have mild pain in the pelvic area and blood in your urine for up to 5 days. Also, you may have some discoloration of your semen for up to 1 month after the biopsy. If you had a transrectal biopsy, you may experience a small amount of bleeding from your rectum for 2 to 3 days after the biopsy.
If you have a transurethral biopsy, you may have a urinary catheter in place for a few hours after the biopsy. You also may need to take an antibiotic medicine for several days after the biopsy.
If you have a general anesthetic, you will be in a recovery room for a few hours after the biopsy. You will need someone to drive you home when you are released. When you get home, your muscles may ache and you may feel tired for the rest of the day.
