What Is A Prostate Ultrasound And Biopsy And Why Would You Need One

How deep does a biopsy go and does it hurt?

The prostate is the part of your body that makes fluid for semen, which is the fluid that carries sperm. The gland surrounds part of your urethra, which is the tube that carries urine and sperm outside of the body. The prostate has muscles that move the sperm out of the body.

If you are having problems with your prostate, you might be having difficulties related to pushing urine or sperm out of your urethra and penis. Your healthcare provider may ask you to have a prostate ultrasound and biopsy to check for prostate cancer.

A prostate ultrasound probe is inserted into the rectum and uses sound waves to produce images inside the rectum to help image the prostate and guide the doctor in taking a biopsy of the prostate gland. Prostate ultrasound and biopsy are used to diagnose prostate cancer or to find the reason for other problems. A doctor may require this test if a patient has high levels of prostate-specific antigen found in a blood test, or has an abnormal prostate exam both suggesting that the patient may have a high risk for prostate cancer.

Comparison Of Mri/us Fusion

Emerging evidence has shown that multiparametric magnetic resonance imaging as an innovative guidance approach for prostate biopsy increases the detection rate of prostate cancer. Hence, we also reviewed RCT studies comparing MRI/US fusion-guided biopsy and traditional systematic transrectal biopsy. This review was not included in our meta-analysis as our aim was to assess the diagnosis accuracy of transperineal and transrectal biopsy.

In the other RCT study by Kasivisvanathan et al. , the authors randomized 252 patients in an MRI-targeted group and 248 patients in a standard biopsy group. In the MRI-targeted group, 71 patients did not undergo prostate biopsy because of negative MRI results. The patients in the MRI-targeted group received a 4-core MRI/US fusion biopsy and the patients in the standard biopsy group received a systematic transrectal biopsy. Clinically significant prostate cancer was diagnosed in 38% patients in the MRI-targeted group and 26% patients in the standard biopsy group. The detection rate of the MRI-targeted biopsy is significantly higher than the traditional biopsy.

Types Of Prostate Biopsy

A prostate biopsy may be done in several different ways:

  • Transrectal method

At the moment, most biopsies are done using a transrectal ultrasound-guided technique. A TRUS prostate biopsy is where the needle goes through the wall of the back passage .

  • Perineal method

This is done through the skin between the scrotum and the rectum.

  • Transurethral method

This is a type of biopsy done through the urethra using a cystoscope .

  • Transperineal biopsy

Unlike the TRUS Guided Biopsy, this is where the doctor inserts a needle into the prostate through the skin between the testicles and the anus. This area is the perineum.

The needle is inserted through a template or grid. This is a targeted biopsy, which can be target a specific area of the prostate using MRI scans. An advantage of the TP biopsy is that it can now be performed under local anesthesia.

What Is A Prostate Biopsy

A prostate biopsy is a procedure to detect prostate cancer. They remove small samples of the prostate and then observed them under the microscope.

Doctors usually recommend a biopsy of your prostate gland based on certain findings. One is if your prostate-specific antigen blood test results are higher than average for your age.

Another is if your doctor detects signs of a prostate problem during your digital rectal exam . Although the PSA and DRE or show a possible problem with your prostate, it requires a biopsy to confirm if its cancer.

A prostate biopsy involves:

  • Collecting minute samples of the prostate gland. The doctor passes a needle through the rectal wall or makes a small cut in the area between the anus and rectum to obtain the samples. A CT or MRI scan is also used to guide them through the procedure.
  • A prostate biopsy takes about 10 minutes and is usually done in the doctors office. The samples will be sent to a lab and will be looked at under a microscope to see if they contain cancer cells.
  • If cancer is detected in the patient, it will also be assigned a grade. The results are available after 1 to 3 days, but it can sometimes take longer.

Things You Need To Take Care

Scared stiff of having a prostate biopsy?

In case, you’re the kind who wouldn’t like to get through an obtrusive and difficult technique like biopsy, regardless you have different alternatives. Do it the natural way.

Change your eating routine. Stay away from food which could trigger prostate diseases. Change your way of life. Get into prostate-accommodating activities.

At last, and most essential of all, take natural supplements which could keep or keep up the health of your prostate, and moderate down the development or wipe out those cancer cells.

In concluding lines, We wouldn’t have any desire to experience pain if we could help it. Biopsy is a painful method. Therefore, you need to think a ton of times before you decide on it. Pain or no pain? The choice is up to you!

Complications Of The Periprostatic Nerve Block

The periprostatic nerve block is a safe technique that is not accompanied by any major complications , if the procedure is carried out after taking proper precautions. The complications associated with the periprostatic nerve block are insignificant , and the periprostatic nerve block does not increase the complication rates of a prostate biopsy . The low complication rates are attributed to the use of a thin injection needle for anesthetic deposition and to the excellent safety profile of lidocaine.

The periprostatic nerve block requires a few extra needle punctures. The pain due to these punctures is the most common side effect, because the actual biopsy becomes painless due to the block .

Vasovagal syncope is rarely reported after the periprostatic nerve block . Another concern is the increase in the risk of infection due to extra punctures in the rectum, but this has not been substantiated by the studies and the risk of infection is negligible as the periprostatic nerve block is performed under antibiotic prophylaxis.

Bleeding complications such as hematuria, hematospermia, and rectal bleeding are not increased after the periprostatic nerve block and are independent of the number of periprostatic nerve block injections . Counterintuitively, the incidence of rectal bleeding is reported to be reduced after the periprostatic nerve block, probably due to less discomfort .

What Is A Transperineal Biopsy

This is where the doctor inserts the biopsy needle into the prostate through the skin between the testicles and the back passage . In the past, hospitals would only offer a transperineal biopsy if other health problems meant you couldnt have a TRUS biopsy. But many hospitals have stopped doing TRUS biopsies and now only do transperineal biopsies.

A transperineal biopsy is normally done under general anaesthetic, so you will be asleep and wont feel anything. A general anaesthetic can cause side effects your doctor or nurse should explain these before you have your biopsy. Some hospitals now do transperineal biopsies using a local anaesthetic, which numbs the prostate and the area around it, or a spinal anaesthetic, where you cant feel anything in your lower body.

The doctor will put an ultrasound probe into your back passage, using a gel to make this easier. An image of the prostate will appear on a screen, which will help the doctor to guide the biopsy needle.

If youve had an MRI scan, the doctor may just take a few samples from the area of the prostate that looked unusual on the scan images. This is known as a targeted biopsy.

How Should I Prepare

Prior to a prostate biopsy, you should provide your physician with a list of all the medications you are taking, including herbal supplements. Tell your doctor if you have any allergies, especially to anesthesia. Also, inform your physician about recent illnesses or other medical conditions.

You may be asked to stop or curtail the use of blood thinning medications for seven to 10 days before the procedure to prevent excessive bleeding during and after the biopsy. A blood test may be required to check your blood clotting on the day of the procedure. Consult your physician and the hospital radiology clinic or department for more information.

You may be advised to take antibiotic pills for a day or two before the biopsy, and on the morning of the procedure, to help prevent infection.

If you are undergoing an MRI-guided biopsy, you will be asked to wear metal-free clothing and remove any metallic objects, such as jewelry, watches, and hearing aids.

A technologist will walk through an MR imaging safety checklist with you. Make sure to inform your technologist of prior surgeries or metal implants, such as pacemakers, aneurysm clips, or joint replacements.

For the MRI-guided procedure, you will receive intravenous contrast material called gadolinium. Because gadolinium does not contain iodine, it can be used safely in patients with contrast allergies.

If you are sedated for the procedure, you will want to have a relative or friend accompany you and drive you home afterward.

Sites Of Injection For The Periprostatic Nerve Block

A painless alternative for prostate cancer biopsies (Full Video)

The sites of injection for the periprostatic nerve block are determined by the location of neurovascular bundles and branches that supply the prostate gland. The completeness of periprostatic nerve block depends on the correct identification of the injection sites. The neurovascular bundles are not directly visualized on ultrasound and their probable location is interpolated from sonographic landmarks. Bilateral symmetrical injections at each site are imperative to achieve complete nerve block due to decussation of fibers in the prostatic plexus. Although some investigators have used a single site of injection, the best results are achieved when these injections are used in combinations. The various sites of injection are as follows:

Bibasal Injections

Introduced by Nash et al., this is the most common site of injection , when used either alone, or more optimally in combination with other sites of injection. It is a preferred site considering that the major neurovascular bundles of the prostate traverse this site and injection at this site anesthetize a large portion of the prostate gland . This site is identified by an echogenic triangle of fat at the angle between the seminal vesicle and base of the prostate in the para-sagittal longitudinal scan. The appearance is similar to the snow peak of a mountain and hence it is called “the Mount Everest sign” .

Bibasal injection.

Apical Injections

Lateral Injections

Intraprostatic Injections

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.

Multiparametric MRI

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.

What Will I Experience During And After The Biopsy

If you receive IV contrast for the MRI-guided procedure, you may feel coolness and a flushing sensation for a minute or two when the contrast material is injected. The intravenous needle may cause you some discomfort when it is inserted and you may experience some bruising once it is removed.

Rarely, patients may experience side effects from the MR contrast material, including nausea and local pain, hives, itchy eyes or other reactions. If you experience allergic symptoms, a radiologist or other physician will be available for immediate assistance.

When the ultrasound probe or endorectal coil is inserted into the rectum, you will feel pressure and may have some temporary discomfort.

You will hear a clicking noise when the biopsy needle samples the prostate, and you may feel a stinging or burning sensation in the area.

Some patients find it uncomfortable to remain still during MR imaging. Others experience a sense of being closed-in . Therefore, sedation can be arranged for those patients who anticipate anxiety.

If you feel heating on your skin at any time during MR imaging, the MR technician should be notified so that they can perform a closer examination of the area.

Some patients experience a small amount of bleeding from the rectum or perineum immediately after the biopsy procedure. If this occurs, it will cease with gentle pressure.

You may feel pain and discomfort in the area of the prostate for a day or two after the biopsy, particularly when you are seated.

Who Interprets The Results And How Do I Get Them

A pathologist examines the removed tissue specimens and makes a final diagnosis. The results usually are available to your physician within a few days of the procedure. The time it takes may vary based on the complexity of the examination, preparation time for the specimens, need for a second opinion and other factors.

Why And How Prostate Biopsy Is Done

Prostate Biopsy

It is important to know how the prostate biopsy is done, especially if you are a man over 50 who has an elevated risk for prostate cancer.

Your doctor may recommend a prostate biopsy if they suspect that you have cancerous cells in your prostatic tissue.

If left untreated, these cells can lead to problems with bladder control and sexual function.

Prostate biopsies are typically performed outpatient under sedation or general anesthesia with the patient awake throughout the procedure.

Would The Method Cause You Torment

Definitely The agony would be because of the anesthesia infusions, as well as be experienced when the specimens are being taken. This is an exceptionally obtrusive technique which could bring about diseases after it is being finished. Infections which are exceptionally agonizing, as well as the kind which couldn’t without much of a stretch be cured by the most grounded anti-microbials.

In reality, biopsy is an extremely difficult method, yet there is no insurance that doing it would cure you from prostate infections, or take out prostate growth cells from your system.

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.

Are There Any Problems To Expect After A Prostate Ultrasound And Biopsy

In some cases, men can develop a urinary tract infection or an infection in the prostate. These infections are rare and easy to treat with prescribed antibiotics.

Blood in the urine and/or stool is common for three to five days after the biopsy. It is also common to have blood in your semen for up to two to three months after the biopsy. This is not harmful to you or your partner and will eventually go away on its own. You should avoid heavy lifting for two to three days to help avoid bleeding issues.

Some men may also have trouble urinating after the procedure. Most problems are minor and go away on their own after a few days. If you arent able to urinate at all, call your healthcare provider or go to the emergency room. Make sure that you tell them that you just had the ultrasound and biopsy.

  • A fever of 100 degrees F or higher.
  • Shaking or chills.

Efficacy Of The Periprostatic Nerve Block

Understanding the Gleason Score on Your prostate Biopsy

The periprostatic nerve block is the most effective technique to provide local anesthesia for prostate biopsy . Although early studies of the periprostatic nerve block for six-core prostate biopsy were equivocal, a large corpus of evidence from randomized controlled studies and meta-analyses proves that the periprostatic nerve block provides substantial pain relief during prostate biopsy. The patients who undergo repeat prostate biopsy usually report significant pain reduction when the periprostatic nerve block is performed . Patients are more comfortable and cooperative during the procedure when the periprostatic nerve block is performed and are more agreeable to undergo repeat biopsy. It also reduces the analgesic requirement during the immediate post-procedure period .
