The prostate gland is found only in males. It sits below the bladder and wraps around the urethra the tube that carries urine out of the body. The prostate helps make semen. A biopsy is a procedure used to remove a small piece of tissue or cells from the body so it can be examined under a microscope. In a prostate biopsy, prostate gland tissue is taken out with a biopsy needle or during surgery.
Your doctor will explain the pathologist's findings Prostzte you. Ultrasound- and MRI-guided prostate biopsy uses imaging guidance and a needle to remove tissue from the prostate in order to examine it for disease. Also, inform your physician about recent illnesses fia other medical conditions. General Medical Council. 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. MRI is also useful in patients who have previously undergone a biopsy and want to improve the sensitivity of the procedure and the Prostate biopsy via urethra of the biopsy.

Health Home Treatments, Tests and Therapies. If you were given general anesthesia, you will be taken to a recovery room for observation. The transperineal biopsy collects the tissue through a urrethra incision in the perineum. The biopsy may also show cells that look abnormal, but may or may not be cancer. The doctor looks directly at the prostate through the cytoscope and Singapore cane skinny male inserts a cutting loop to extract tissue. A prostate biopsy is usually done on Prostate biopsy via urethra bbiopsy basis. When arranging your prostate biopsy, it's helpful to have someone you can talk to about what the test might mean for you and how you are coping emotionally. Some conditions that may result in a suspicious biopsy include:. Types of Prostate Biopsies There are three types of prostate biopsies: the transrectal, the transurethral, and the transperineal. You may also be given antibiotics 30 to 60 minutes before the procedure if you did not receive them the night before the test. After having the prostate biopsy, men may experience blood in their urine and their semen for a few weeks or up Prostate biopsy via urethra two months afterwards. Quon, J. Prostate Gland Anatomy. Systematic review of complications of prostate biopsy.
- Prostate Cancer Treatment Overview.
- Prostate biopsy is a procedure in which small hollow needle-core samples are removed from a man's prostate gland to be examined for the presence of prostate cancer.
- The prostate gland is found only in males.
- A biopsy of the prostate gland is usually required when there is a suspicion of prostate cancer.
- While screening tests may suggest there is a problem, a prostate biopsy is needed to make a prostate cancer diagnosis and determine the aggressiveness of the disease.
- A prostate biopsy is the removal of tiny samples of prostate tissue to examine it for signs of prostate cancer.
If you have any concerns, discuss them with your doctor or specialist nurse before you decide whether to have a biopsy. You may be given some antibiotics to take before your biopsy, either as tablets or an injection, to help prevent infection.
You might also be given some antibiotic tablets to take at home after your biopsy. This is the most common type of biopsy in the UK.
The doctor or nurse uses a thin needle to take small samples of tissue from the prostate. The doctor or nurse will put an ultrasound probe into your back passage rectum , using a gel to make it more comfortable. The ultrasound probe scans the prostate and an image appears on a screen.
The doctor or nurse uses this image to guide where they take the cells from. You will have an injection of local anaesthetic to numb the area around your prostate and reduce any discomfort. The doctor or nurse then puts a needle next to the probe in your back passage and inserts it through the wall of the back passage into the prostate. They usually take 10 to 12 small pieces of tissue from different areas of the prostate. But, if the doctor is using the images from your MRI scan to guide the needle, they may take fewer samples.
The biopsy takes 5 to 10 minutes. After your biopsy, your doctor may ask you to wait until you've urinated before you go home. This is because the biopsy can cause the prostate to swell, so they'll want to make sure you can urinate properly before you leave. This is where the doctor inserts the biopsy needle into the prostate through the skin between the testicles and the back passage perineum. But many hospitals have stopped doing TRUS biopsies and now only do transperineal biopsies.
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. This is known as a targeted biopsy. Or they might decide to take up to 25 samples from different areas of the prostate.
You may hear this called a template biopsy, as the doctor places a grid template over the area of skin between the testicles and back passage.
They then insert the needle through the holes in the grid, into the prostate. A transperineal biopsy usually takes about 20 to 40 minutes. If you've had a general anaesthetic, you will need to wait a few hours to recover from the anaesthetic before going home. And you will need to get someone to take you home. Having a biopsy can cause side effects. These will affect each man differently, and you may not get all of the possible side effects.
Some men feel pain or discomfort in their back passage rectum for a few days after a TRUS biopsy. Others feel a dull ache along the underside of their penis or lower abdomen stomach area. If you have a transperineal biopsy, you may get some bruising and discomfort in the area where the needle went in for a few days afterwards.
If you receive anal sex, wait about two weeks, or until any pain or discomfort from your biopsy has settled, before having sex again. Ask your doctor or nurse at the hospital for further advice. Some men find the biopsy painful, but others have only slight discomfort. Your nurse or doctor may suggest taking mild pain-relieving drugs, such as paracetamol, to help with any pain.
You may also notice blood in your semen for a couple of months — it might look red or dark brown. This is normal and should get better by itself. If it takes longer to clear up, or gets worse, you should see a doctor straight away. A small number of men less than 1 in who have a TRUS biopsy may have more serious bleeding in their urine or from their back passage rectum. This can also happen if you have a transperineal biopsy but it isn't very common. If you have severe bleeding or are passing lots of blood clots, this is not normal.
Some men get an infection after their biopsy. This is more likely after a TRUS biopsy than after a transperineal biopsy. But you might still get an infection even if you take antibiotics. If you have any of these symptoms, contact your doctor or nurse at the hospital straight away. Around 3 in men three per cent who have a TRUS biopsy get a more serious infection that requires going to hospital.
If the infection spreads into your blood, it can be very serious. This is called sepsis. Symptoms of sepsis may include:. This happens because the biopsy can cause the prostate to swell, making it difficult to urinate. Acute urine retention may be more likely if you have a template biopsy.
This is because more samples are taken, so there may be more swelling. Your doctor will make sure you can urinate before you go home after your biopsy. You might need a catheter for a few days.
You can masturbate and have sex after a biopsy. If you have blood in your semen, you might want to use a condom until the bleeding stops. A small number of men have problems getting or keeping an erection erectile dysfunction after having a biopsy.
This may happen if the nerves that control erections are damaged during the biopsy. The biopsy samples will be looked at under a microscope to check for any cancer cells. Your doctor will be sent a report, called a pathology report, with the results. The results will show whether any cancer was found. They may also show how many biopsy samples contained cancer and how much cancer was present in each sample. It can take up to two weeks to get the results of the biopsy.
Ask your doctor or nurse when you're likely to get the results. You might be sent a copy of the pathology report. And you can ask to see copies of letters between the hospital and your GP. If you have trouble understanding any of the information, ask your doctor to explain it or speak to our Specialist Nurses. I asked to see the letters from the hospital to my GP. If cancer is found, this is likely to be a big shock, and you might not remember everything your doctor or nurse tells you.
It can help to take a family member, partner or friend with you for support when you get the results. You could also ask them to make some notes during the appointment. It could help to ask your doctor if you can record the appointment using your phone or another recording device.
But let your doctor or nurse know if and why you are recording them as not everyone is comfortable being recorded. Your biopsy results will show how aggressive the cancer is — in other words, how likely it is to spread outside the prostate. You might hear this called your Gleason grade, Gleason score, or grade group.
The pattern is given a grade from 1 to 5 — this is called the Gleason grade. Grades 1 and 2 are not included on pathology reports as they are similar to normal cells. If you have prostate cancer, you will have Gleason grades of 3, 4 and 5. The higher the grade, the more likely the cancer is to spread outside the prostate. There may be more than one grade of cancer in the biopsy samples. An overall Gleason score is worked out by adding together two Gleason grades.
The first is the most common grade in all the samples. When these two grades are added together, the total is called the Gleason score. Your doctor might also talk about your "grade group". This is a new system for showing how aggressive your prostate cancer is likely to be. Your grade group will be a number between 1 and 5 see table. The higher your Gleason score or grade group, the more aggressive the cancer and the more likely it is to grow and spread. We've explained the different Gleason scores and grade groups that can be given after a prostate biopsy below.
This is just a guide. Your doctor or nurse will talk you through what your results mean. There are some cancer cells that look likely to grow at a moderate rate grade group 2. There are some cancer cells that look likely to grow slowly grade group 3.
The biopsy will also help set the course for treatment. Also, patients who opt for local anesthesia may be groggy for a short time after the prostate biopsy. They will be sent to the lab for examination. During the procedure you may feel: Mild discomfort while the probe is inserted A brief sting when a sample is taken with the biopsy needle After the procedure, you may have: Soreness in your rectum Small amounts of blood in your stools, urine, or semen, which may last for days to weeks Light bleeding from your rectum To prevent infection after the biopsy, your provider may prescribe antibiotics to take for several days after the procedure. A relative contraindication to a prostate biopsy is the use of blood thinners that cannot be stopped for the procedure. Other prostate biopsy methods are used, but not very often.
Prostate biopsy via urethra. Navigation menu
If the biopsy reveals no cancerous cells, either you do not have prostate cancer , or the prostate biopsy missed the tumor. If the doctor believes the biopsy missed a tumor based on other factors such as your family history, a particular irregularity in the digital rectal exam , or a rising PSA density, you will receive a follow-up biopsy in six months.
Seventy-five percent of men have negative primary prostate biopsies. Before the Prostate Biopsy Before undergoing the biopsy, a patient may take antibiotics to reduce the risk of infection after the prostate biopsy. The patient also should stop anti-inflammatory drugs , such as aspirin or ibuprofen, that may increase the risk of bleeding after the biopsy.
Finally, the doctor may also order an enema before the prostate biopsy to remove feces and gas that may complicate the transrectal biopsy. Types of Prostate Biopsies There are three types of prostate biopsies: the transrectal, the transurethral, and the transperineal. The transrectal prostate biopsy is guided by the transrectal ultrasound TRUS through the anus and into the rectum.
The transurethral biopsy is performed with a lighted cystoscope up through the urethra so the doctor can look directly at the prostate gland. The transperineal biopsy collects the tissue through a small incision in the perineum. The transrectal and transperineal prostate biopsies both use spring-loaded needles to collect their samples as quickly, efficiently, and painlessly as possible. The biopsy gun can collect between 6 and 13 samples, depending on how many a doctor believed is necessary to diagnose you correctly.
Transperineal Prostate Biopsy Patients opting to undergo the transperineal biopsy may also be put under general anesthesia if they wish to be unconscious during the biopsy. Men who opt to have the transperineal biopsy performed may experience some tenderness as well as blood in the semen for one to two months afterwards.
Transrectal Prostate Biopsy In the transrectal biopsy, transrectal ultrasound guides the doctor and the biopsy gun to the proper place. Patients who opt for this prostate biopsy may experience a small amount of bleeding from the rectum as well as blood and urine in the semen afterwards. Transurethral Prostate Biopsy The transurethral biopsy inserts the cystoscope into the urethra. Local anesthesia is given to numb the area.
The doctor looks directly at the prostate through the cytoscope and then inserts a cutting loop to extract tissue. The cutting loop works by turning and extracting a small amount of tissue with each turn.
Side Effects of Prostate Biopsy Only minimal pain is associated with both procedures, though, doctors are more commonly using local anesthesia to numb the tested area. After having the prostate biopsy, men may experience blood in their urine and their semen for a few weeks or up to two months afterwards.
Some soreness or minimal bleeding after the transperineal biopsy may also be experienced for a few days. Some doctors recommend having someone drive the patient home to avoid unpleasantness or soreness. Also, patients who opt for local anesthesia may be groggy for a short time after the prostate biopsy. Patients may return to normal activities as soon as they feel able.
In all three procedures, the pathologist needs multiple samples from different areas of the prostate to make an accurate diagnosis. Remember, if a tumor is small enough, it can be missed during the prostate biopsy. You may have to sign a consent form. To prevent infection after the biopsy, your provider may prescribe antibiotics to take for several days after the procedure. Be sure you take the full dose as directed. A positive biopsy result means that cancer cells have been found.
The lab will give the cells a grade called a Gleason score. This helps predict how fast the cancer will grow. Your doctor will talk to you about your treatment options. The biopsy may also show cells that look abnormal, but may or may not be cancer.
Your provider will talk with you about what steps to take. You may need another biopsy. Biopsy prophylaxis, technique, complications, and repeat biopsies. Prostate Cancer: Science and Clinical Practice. Waltham, MA: Elsevier; chap 9. Prostate biopsy: techniques and imaging. Campbell-Walsh Urology. Philadelphia, PA: Elsevier; chap Review provided by VeriMed Healthcare Network. Editorial team. Prostate biopsy. How the Test is Performed.
There are three main ways to perform a prostate biopsy. You will be asked to lie still on your left side with your knees bent. The health care provider will insert a finger-sized ultrasound probe into your rectum. You may feel a little discomfort or pressure.
The ultrasound allows the provider to see images of the prostate. Using these images, the provider will inject a numbing medicine around the prostate. Then, using ultrasound to guide the biopsy needle, the provider will insert the needle into the prostate to take a sample. This may cause a brief stinging sensation. About 10 to 18 samples will be taken.
They will be sent to the lab for examination. The entire procedure will take about 10 minutes. Other prostate biopsy methods are used, but not very often.
Prostate biopsy: MedlinePlus Medical Encyclopedia
Ultrasound- and MRI-guided prostate biopsy uses imaging guidance and a needle to remove tissue from the prostate in order to examine it for disease. The ultrasound probe used in prostate biopsies is about the size of a finger. Once the probe is placed in the rectum, the biopsy is performed with a spring-driven needle core biopsy device, or biopsy gun. The MRI-guided biopsy can be performed with an endorectal approach or a transperineal approach. For the endorectal biopsy, the patient is usually lying on his stomach.
The biopsy device has a built in endorectal coil to aid in visualization and a guidance slot for biopsy needle insertion. For the transperineal biopsy, the patient is usually lying on his back and the biopsy is generally performed with a guidance grid placed against the perineum just below the scrotum.
Biopsy is currently the only way to definitively diagnose prostate cancer. It is also used to differentiate between cancer and benign prostatic hyperplasia, a common condition in older men.
Your doctor will instruct you based on the type of biopsy being performed. Tell your doctor about any medications you're taking, including aspirin and herbal supplements, and whether you have any allergies — especially to anesthesia.
Your physician will advise you to stop taking aspirin or blood thinner seven to 10 days before your procedure. You may be told to eat light meals before your procedure and asked to clear your bowel. Leave jewelry at home and wear loose, comfortable clothing. You may be asked to wear a gown.
Ultrasound- and MRI-guided prostate biopsies are performed to collect tissue samples from the prostate gland for examination by a pathologist to determine whether or not the tissue is cancerous.
Biopsies are most commonly performed under ultrasound guidance. During the procedure, a special biopsy needle is inserted into the prostate gland through the wall of the rectum to remove several small samples of tissue for pathologic analysis. This method is known as transrectal ultrasound TRUS guided biopsy. The prostate may also be accessed through the perineum the area of skin between the base of the penis and the rectum.
This method is known as the transperineal approach and may be used for one of several reasons:. Prostate biopsies can also be performed utilizing information from MR imaging, which provides more detailed images of the prostate than is possible with ultrasound. Before the biopsy, prostate MR images are examined, sometimes also with the help of computer-aided detection CAD software to pinpoint specific areas that may require further evaluation.
MRI-guided in-bore biopsy can be performed using either a transperineal or transrectal approach. Both methods typically utilize software to guide the course of the needle to the desired position within the prostate. This approach has the advantage of using the superior imaging of the MRI coupled with easier-to-use ultrasound guidance and can be done in the office setting. 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 DRE , a common prostate cancer screening test. A biopsy also may be ordered when a blood test reveals elevated levels of prostate-specific antigen.
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. 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. Your MR imaging exam may involve the use of an endorectal coil , a thin wire covered with a latex balloon and placed inside the end of the rectum. If you are allergic to latex, you need to let the MR technologist know so that they may cover the coil with a latex-free balloon.
You should eat light meals on the day prior to and on the day of your exam. This will help make it easier to insert the ultrasound probe or endorectal coil. You may also be asked to use an enema preparation prior to your exam. An enema involves injecting liquid into your rectum to help clear the bowel.
Enema kits or saline laxatives can be bought over-the-counter. The physician should also know if you have any serious health problems, or if you have recently had surgery. Some conditions, such as severe kidney disease, may prevent you from being given contrast material for an MR exam. If there is a history of kidney disease, it may be necessary to perform a blood test to determine whether the kidneys are functioning adequately. If you are sedated for the procedure, you will want to have a relative or friend accompany you and drive you home afterward.
Ultrasound scanners consist of a console containing a computer and electronics, a video display screen and a transducer or probe that is used to do the scanning. The transducer sends out inaudible high frequency sound waves into the body and then listens for the returning echoes. The principles are similar to sonar used by boats and submarines. The ultrasound image is displayed on a video screen that looks like a computer or television monitor.
The resulting image is based on the amplitude loudness and frequency pitch of the signal. The ultrasound image makes an image taking into account signal travel time, tissue composition, and type of body structure through which the sound travels. The handheld device includes a long but very thin needle specially designed to open inside the prostate, take the sample and then close.
The traditional MRI unit is a large cylinder-shaped tube surrounded by a circular magnet. You will lie on a table that slides into the center of the magnet. Some MRI units, called short-bore systems , are designed so that the magnet does not completely surround you. Some newer MRI machines have a larger diameter bore, which can be more comfortable for larger patients or those with claustrophobia. They are especially helpful for examining larger patients or those with claustrophobia.
Open MRI units can provide high quality images for many types of exams. Certain exams cannot be performed using open MRI. For more information, consult your radiologist. The appropriate needle path is selected for biopsy needle insertion.
Both MR biopsy techniques utilize software to fuse the biopsy needle guides with the MR images to obtain a more accurate needle placement. 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.
Instead, radio waves re-align hydrogen atoms that naturally exist within the body. This does not cause any chemical changes in the tissues. As the hydrogen atoms return to their usual alignment, they emit different amounts of energy depending on the type of body tissue they are in. The scanner captures this energy and creates a picture using this information. In most MRI units, the magnetic field is produced by passing an electric current through wire coils. Other coils are located in the machine and, in some cases, are placed around the part of the body being imaged.
These coils send and receive radio waves, producing signals that are detected by the machine. The electric current does not come in contact with the patient.
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. MRI is able to tell the difference between diseased tissue and normal tissue better than x-ray, CT and ultrasound.
The endorectal coil used in an MRI-guided prostate biopsy helps provide more detailed images from the prostate and surrounding structures. It also enables your radiologist to perform MR spectroscopy , which can provide additional information on the chemical makeup of cells present in the prostate gland.
