Prostate Ultrasound with Biopsy
During a prostate ultrasound, a probe about the size of a finger is placed a short distance into the rectum. This probe creates images of the prostate gland. The probe helps your doctor see the size of your prostate and detect any abnormal growths.
During a prostate biopsy, ultrasound helps to guide the small needle through the rectum into areas of the prostate where abnormal tissues may be detected. The needle is used to collect tissue samples from these areas.
While lying on your left side, with your knees drawn up, the ultrasound probe will be placed into the rectum and the biopsies are taken. You may feel pressure as the samples are taken. It takes about 5 minutes to get the samples. After the biopsy is done, you may need to stay until you are able to urinate.
____ Prostate Biopsy done in the Clinic:
- You may eat before the test.
- You will need a sodium phosphate enema (Fleets Enema) before the test. Give it 1-1 ½ hours before you leave to come to the clinic. Follow the directions on the box. Shower.
____ Prostate Biopsy done in the Operating Room:
- Stop all solid foods, dairy products, and juices with pulp at midnight. You may be able to have small amounts of clear liquid up to 4 hours before.
- You will need a sodium phosphate enema (Fleets Enema) before the test. Give it 2 to 4 hours before you leave home. Shower.
- You will receive a call from the Ambulatory Procedure Center the day before your scheduled biopsy to tell you when to arrive and when your procedure will start.
Before the Test
1. Tell your doctor if you have an artificial joint that has been placed in the last
2 years because you may need more antibiotics before the biopsy.
2. You should stop taking the other “blood thinning” medicines 1 week before
the test. Examples are: (Coumadin® warfarin, Advil®, Motrin®, Nuprin®,
aspirin, Vitamin E, and ibuprofen). Discuss taking any prescription blood
thinning medicines with the prescribing provider. These are medicines that
can cause an increased chance of bleeding after the biopsy.
3. You will need to give a urine sample before the test. It is helpful
to have a full bladder when you arrive at the clinic.
4. You will take antibiotics before and after the biopsy. It is important to take
them as directed.
After the Biopsy
1. Take antibiotics as directed.
2. Nothing strenuous for 1-2 days.
3. No intercourse for 3 days. Your semen may have blood in it and remain
rusty colored for several weeks.
4. Drink plenty of fluids after the biopsy, 8-10 (8 oz.) glasses each day.
When to Call the Doctor
