Things To Know Before Getting A Prostate Biopsy
Additional Tests That May Aid Prostate Cancer Diagnosis
There are few other diagnostic tools or tests, which can be performed before you have a prostate biopsy, that may help your physician gather more information about your specific case. These procedures may help determine the likelihood of the presence of cancer and its aggressiveness and increase the accuracy of a biopsy when performed. Those tests include:
4Kscore blood test is a molecular test that helps predict the likelihood and risk of a patient having aggressive prostate cancer. If you’re a patient whose PSA values are borderline for a prostate biopsy or you have a condition that could be aggravated by a biopsy, your physician may use this test before to help determine whether you should get a biopsy or a repeat biopsy.
Urine sample testlooks for biomarkers that may indicate the presence of prostate cancer cells in a patient’s body. This test may also be helpful when trying to determine whether a patient should be rebiopsied or not.
The use of multiparametric MRI imaging of the prostate gland before a biopsy has been a game changer in prostate cancer diagnosis, increasing the accuracy of biopsies over standard biopsies. The mpMRI doesn’t replace the standard biopsy, but by improving its accuracy, it may help decrease the number of biopsies needed.
The mpMRI has a higher resolution than a standard prostate ultrasound. This increases the ability to see suspicious lesions in the prostate, providing additional targets for the biopsy to sample.
Use In Men Who Might Have Prostate Cancer
The PSA blood test is used mainly to screen for prostate cancer in men without symptoms. Its also one of the first tests done in men who have symptoms that might be caused by prostate cancer.
PSA in the blood is measured in units called nanograms per milliliter . The chance of having prostate cancer goes up as the PSA level goes up, but there is no set cutoff point that can tell for sure if a man does or doesnt have prostate cancer. Many doctors use a PSA cutoff point of 4 ng/mL or higher when deciding if a man might need further testing, while others might recommend it starting at a lower level, such as 2.5 or 3.;
- Most men without prostate cancer have PSA levels under 4 ng/mL of blood. Still, a level below 4 is not a guarantee that a man doesnt have cancer.
- Men with a PSA level between 4 and 10 have about a 1 in 4 chance of having prostate cancer.;
- If the PSA is more than 10, the chance of having prostate cancer is over 50%.
If your PSA level is high, you might need further tests to look for prostate cancer.;
To learn more about how the PSA test is used to look for cancer, including factors that can affect PSA levels, special types of PSA tests, and what the next steps might be if you have an abnormal PSA level, see Screening Tests for Prostate Cancer.

What Should I Expect From A Prostate Biopsy
A prostate biopsy may be recommended if the results of a digital rectal examination or prostate-specific antigen test suggest that prostate cancer may be present. The most common approach for performing this diagnostic test is transrectal, in which a needle is carefully passed through the wall of the rectum to retrieve a prostate tissue sample.
Going Home With A Catheter
You will be discharged from the hospital with a catheter in place to drain urine from your bladder into a bag. The doctor will remove this in the office in five to 14 days. Be sure to clean the catheter where it exits your penis twice a day with soap and water and to empty the bag frequently. The bag should always be positioned lower than your bladder.
On occasion, the catheter may irritate the bladder, causing bladder spasms that can be quite uncomfortable. If these occur, your doctor can prescribe medication that can help. Leakage of urine around where the catheter exits the penis also may occur and can be managed by wearing incontinence pads as described in the next section.
It is normal for your urine to look cloudy for a few weeks after surgery. Occasionally, bleeding may occur around the catheter or be noticed within the urine. This also is common. If you see large clots â more than an inch in length â or if the catheter becomes plugged, contact your doctor. No anesthesia is required for catheter removal, and most patients experience only a little discomfort.

Prostate Biopsy At A Glance
- A prostate biopsy is the removal of tissue samples from the male prostate gland so a laboratory can examine the tissue for the presence of prostate cancer.
- A biopsy is generally recommended when a prostate-specific antigen screening, a digital rectal exam or an imaging test indicate a suspicious area that requires further examination.
- We will discuss our findings with the patient and the prospect of conducting a prostate biopsy to learn more.
- Urologists perform the removal of the tissue in our offices using transrectal ultrasound and a small needle to obtain cell samples from the prostate for a biopsy.
- The biopsies are sent to the pathology lab where they are stained and reviewed by a pathologist, with results typically available;within one week of the biopsy.
- Prostate biopsy is the only method of definitively diagnosing prostate cancer.
After Prostatectomy: What To Expect
At the hospital : You should expect to be in the hospital for one night. At Johns Hopkins, all rooms on the urology floor are private. Here, nurses help patients get moving shortly after surgery to prevent blood clots and other postoperative risks.
First few days at home : After youre sent home, you might find that regular ibuprofen or acetaminophen will be sufficient pain management for the first few days. If over-the-counter medications arent enough, your doctor can help you with alternatives.
One week after surgery : After your surgery site heals, your catheter will be removed. This is usually seven to 10 days after surgery. This can easily be done at your doctors office. Some people decide to take out their catheter at home. If thats the case, ask your doctor for instructions first.
This is also about the time your surgeon will call you with the final pathology results. He or she will discuss what you should know and whether further treatment is necessary.
One month after surgery : Doctors recommend no strenuous activity or heavy lifting for at least one month after surgery. Most people take off work for three to four weeks. If you work from home, you could return to work sooner.

- Erectile dysfunction
Recovery from surgery takes time. These side effects are often temporary. However, if they are affecting your quality of life, ask your doctor about options that can help.

What Are The Limitations Of Ultrasound
A biopsy can only show if there is cancer in the samples taken, so it is possible that cancer in unsampled areas of the prostate might be missed.
For MRI-guided biopsies, high-quality images are assured only if you are able to remain perfectly still while the images are being recorded. If you are anxious, confused or in severe pain, you may find it difficult to lie still during imaging, and the resulting images may not be of sufficient quality to be useful as a diagnostic tool.
Likewise, the presence of an implant or other metallic object sometimes makes it difficult to obtain clear MR images. A person who is very large may not fit into the opening of certain types of MRI machines.
MR imaging cannot always distinguish between cancer tissue and inflammation or the presence of blood products within the prostate, which sometimes occurs related to a prostate biopsy. To avoid confusing the two on imaging, prostate MR imaging may be performed six to eight weeks after prostate biopsy, if possible, to allow any residual bleeding to resolve itself.
MRI typically costs more and may take more time to perform than other imaging methods. Talk to your insurance provider if you have concerns about the cost of MRI.
Dealing With Bph Since 2003
Based on the experience of 2003, I will never again have a prostate biopsy. Since having my left cancerous kidney removed in April of 2015, the condition of my prostate has been monitored by more PSA tests and semi-annual prostate sonograms. My new urologist has me on the drug Avodart containing dutasteride to help shrink the prostate and another, Harnal containing tamsulosin hydrochloride, which makes it easier for me to urinate during the night.

Things You Should Expect After Prostate Surgery
Prostate removal is a major type of surgery and requires time for the body to recover. Even though robotic prostatectomy using the Da Vinci robot has less severe effects on the body and the patient can leave the hospital the same day, men should expect some changes in order to know how to deal with them. The surgery is performed through small incisions that are barely sensitive at the incision sites and the scar tissue is almost unnoticeable. Typically, the recovery is fast, most men are able to go home the next day and resume driving and working in two to three weeks after the surgery.
In the immediate hours after surgery:
Biopsy: Things You Need To Know
The first thing you should know is that theres still plenty of room for confusion after a biopsy. The prostate in a young man is about the size of a walnut; with age and BPH it can get bigger think of a lime, or a lemon, or even an orange. ;Now, imagine that you have about 14 tiny needles; each needle has a hollow center, and when it is stuck into the prostate, it takes out a very small core of tissue. ;Theres a lot of potential to miss any cancer that might be hiding in there.
This is why many men end up getting multiple repeat biopsies, says NYU urologist Stacy Loeb, M.D. ;This means that you might have a PSA that is elevated. ;Your doctor orders a biopsy, and no cancer is found. ;But the PSA keeps on creeping up, so your doctor recommends another biopsy, and maybe even another. ;About a third of men in one study got another biopsy within five years of a negative biopsy, says Loeb. ;If the PSA is elevated, do we do another biopsy, or what do we do? ;This is where some of the second-line PSA tests, like the Prostate Health Index or 4K Score, can be helpful.
A urine test, called the PCA3 test, may also be helpful. ;Unlike the PSA test, which is prostate-specific but not cancer-specific , the PCA3 test targets genes produced by prostate cancer cells.
First, it can hurt.;To get to the prostate, the doctor goes through your rectum. ;With needles. To minimize pain, your urologist may use conscious sedation or an anesthetic called a prostatic block .

Prostate Biopsy Side Effects Are Common
Complications from prostate biopsies are common but usually not severe, a study in Urology reveals. Participants in the study had biopsies to look for cancer after an abnormal rectal exam or prostate-specific antigen blood test. In a biopsy, a fine needle punches quickly through the rectal wall to remove a tiny sample of prostate tissue for examination under a microscope. Doctors took 12, 18, or 24 samples per participant. Typical problems from biopsy include pain, soreness, and infections. A more serious complication, which may lead to hospital admission, is acute urinary retention, in which a man is temporarily unable to drain his bladder.
Here is what the study found:
40% of the men experienced a complication.
The complication rate was as high as 57% in men with 24-sample biopsies.
Only 1.2% of the men required hospital admission.
9.1% ended up visiting an emergency room.
6.7% developed acute urinary retention.
Prostate needle biopsy is the only way to diagnose prostate cancer, regardless of PSA test results. The complication rate would vary with the general health of the men involved.

Patients Reports May Aid Prostate Cancer Treatment Choice
But the genetic tests are pricey, around $3,000 or $4,000, and not necessarily covered by insurance. More problematic, they do not give a yes/no answer to whether cancer cells are harmless. Instead, they indicate whether a man has a very low, low, intermediate, or high risk of harboring an aggressive, metastatic cancer.
The problem is, genetic tests dont necessarily shift the risk much, said Mayos Karnes. A man might have a 30 percent risk of an aggressive cancer, before a genetic test, and the test might shift that to 35 percent. What you want is a test that tells you the risk is more like 0 percent or 100 percent.
Even short of perfection, however, genetic tests are offering men reassurance that they can choose active surveillance rather than treatment. Duane Foulkes, 70, recently sold the manufacturing business he founded near Madison, Wis., when, in late 2015, his PSA test came back over 5. It rose to above 9 three months later, and he had a biopsy at Mayo. His Gleason score of 6 concerned me at first, Foulkes said.
But a genetic test;indicated that he had at most a slow-growing, non-aggressive type of cancer, Foulkes said, giving him confidence to;choose active surveillance.

What Are Some Common Uses Of The Procedure
A prostate biopsy is currently the only way to definitively diagnose prostate cancer. It also helps differentiate cancer from benign prostatic hyperplasia;or nodular enlargement of the prostate, a very common condition in middle-aged and older men that requires a different treatment approach than that of cancer.
A prostate biopsy may be ordered if the physician detects a nodule or other abnormality on the prostate during a digital rectal examination;, a common prostate cancer screening test.
A biopsy also may be ordered when a blood test reveals elevated levels of prostate-specific antigen. While there are several reasons for an elevated PSA level, higher PSA levels are sometimes associated with cancer. PSA trends over time may trigger your physician to order a biopsy.
MRI-guided prostate biopsy may be used in patients who have a rising PSA level yet a negative ultrasound-guided biopsy. It also may be used in situations where a diagnostic prostate MRI performed due to rising PSA demonstrates a very small abnormality that may not be easily targeted by ultrasound. MRI is also useful in patients who have previously undergone a biopsy and want to improve the sensitivity of the procedure and the precision of the biopsy.
A biopsy not only detects cancer; it also provides information on the aggressiveness of the cancer and helps to guide treatment decisions.
How Does The Procedure Work
Ultrasound imaging is based on the same principles involved in the sonar used by bats, ships and fishermen. When a sound wave strikes an object, it bounces back, or echoes. By measuring these echo waves, it is possible to determine how far away the object is as well as the object’s size, shape and consistency. This includes whether the object is solid or filled with fluid.
In medicine, ultrasound is used to detect changes in the appearance of organs, tissues, and vessels and to detect abnormal masses, such as tumors.
In an ultrasound exam, a transducer;both sends the sound waves and records the echoing waves. When the transducer is pressed against the skin, it sends small pulses of inaudible, high-frequency sound waves into the body. As the sound waves bounce off internal organs, fluids and tissues, the sensitive receiver in the transducer records tiny changes in the sound’s pitch and direction. These signature waves are instantly measured and displayed by a computer, which in turn creates a real-time picture on the monitor. One or more frames of the moving pictures are typically captured as still images. Short video loops of the images may also be saved.
A computer processes the signals and creates a series of images, each of which shows a thin slice of the body. These images can be studied from different angles by the radiologist.
