Test urologia prostata

Screening del tumore prostatico e test del PSA - Prostata non sei solo

Dopo il trattamento della prostata

The prostate is a walnut-shaped gland that is part of the male reproductive system. It has two or more lobes, or sections, enclosed by an outer layer of tissue.

Test urologia prostata prostate is located in front of the rectum and just below the bladder, where urine test urologia prostata stored. It surrounds the urethra at the neck of the bladder and supplies fluid that goes into semen.

The most common prostate problem in men younger than age 50 is inflammation, called prostatitis. Prostate enlargement, or benign prostatic hyperplasia BPHis another common problem.

Because the prostate continues to grow as a man ages, BPH is the most common prostate problem for men older than age Older men are at risk for prostate cancer as well, but test urologia prostata is much less common than BPH. Different prostate problems may have similar symptoms. For example, one man with prostatitis and another with BPH may both experience urinary urgency. Sometimes symptoms for the same prostate problem differ among individuals.

For example, one man with BPH may have trouble beginning a urine stream, while another may experience nocturia. A man in the early stages of prostate cancer may have no symptoms at all. Because of this confusing array of symptoms, a thorough medical exam and testing are vital. To diagnose prostate problems, the health care provider will perform a digital rectal exam DRE.

The health care provider will also ask the patient. Answers to these questions will help the health care provider identify the problem or determine what medical tests are needed. Diagnosing BPH may require a series of medical exams and tests.

A DRE is a physical exam of the prostate. The health care provider will ask the patient to bend over a table or lie on his side while holding his knees close test urologia prostata his chest.

The health care provider slides a gloved, lubricated finger into the rectum and feels the part of test urologia prostata prostate that lies next to it. The DRE may be slightly uncomfortable, but it is brief.

This exam reveals whether the prostate has any abnormalities that require more testing. If an infection test urologia prostata suspected, the health care provider might massage the prostate during the DRE to obtain fluid to examine with a microscope. This exam is usually test urologia prostata first. Many health care providers perform a DRE as part of a routine physical exam for men age 50 or older, some even at age test urologia prostata, whether or not the man has urinary problems.

The first test for detecting prostate problems is a blood test to measure prostate-specific antigen PSAa protein made only by the prostate gland. This test is often included in routine physical exams for men older than age Because African American men have higher rates of getting, and dying from, prostate cancer than men of other racial or test urologia prostata groups in the United States, medical organizations recommend a PSA blood test be given starting at age 40 for African American men.

Medical organizations also recommend a PSA blood test be given starting at age 40 for men with a family history of prostate cancer. Some medical organizations even recommend a PSA blood test be given to all men starting at age If urination problems are present or if a PSA blood test indicates a problem, additional tests may be ordered. These tests may require a patient to change his diet or fluid intake or to stop taking medications. If the tests involve inserting instruments into the urethra or rectum, antibiotics may be given before and after the test to prevent infection.

A PSA blood test is performed to detect or rule out prostate cancer. The amount of PSA in the blood is often higher in men test urologia prostata have prostate cancer. However, an elevated PSA level does not necessarily indicate prostate cancer. The U. Food and Drug Administration has approved the PSA blood test urologia prostata for use in conjunction with a DRE to help detect prostate cancer in men age 50 or older and for monitoring men with prostate cancer after treatment.

However, much remains unknown about how to interpret a PSA blood test, its ability to discriminate between cancer and problems such as BPH and prostatitis, and the best course of action if the PSA level is high. However, the test is known to have relatively high false-positive rates. A PSA blood test also may identify a greater number of medically insignificant lumps or growths, called tumors, in the prostate.

Health care providers and patients should weigh the benefits of PSA blood testing against the risks of follow-up diagnostic tests. The procedures used to diagnose prostate cancer may cause significant side effects, including bleeding and infection.

If the DRE or the PSA blood test indicates a problem may exist, the health care provider may order additional tests, including urinalysis, urodynamic tests, cystoscopy, abdominal ultrasound, transrectal ultrasound with prostate biopsy, and imaging studies such as magnetic resonance imaging MRI or computerized tomography CT scan. Urinalysis is the testing of a urine sample for abnormal substances or signs of infection.

If an infection is suspected, the health care provider may ask that the urine sample be collected in two or three containers during a single urination to help locate the infection site.

After the first collection, the health care provider will have the patient stop the urine stream for a prostate massage before collecting more urine. Test urologia prostata signs of infection appear in the first container but not in the others, the infection is likely to be in the urethra.

If the test urologia prostata contains significantly more bacteria after the prostate massage or bacteria are in the prostate fluid itself, the infection is likely to be in the prostate. Urodynamic testing is any procedure that looks at how well the bladder, sphincters, and urethra are storing and releasing urine. If the prostate problem appears to be related to urine blockage, the health care provider may recommend tests that measure bladder pressure and urine flow rate.

One test involves urinating into a special device that measures how quickly the urine test urologia prostata flowing and records how many seconds it takes for the peak flow rate to be reached.

Another test measures postvoid residual, the amount of urine left in the bladder when urination stops. A weak urine stream and urinary retention may be signs of urine blockage caused by an enlarged prostate that is squeezing test urologia prostata urethra.

Cystoscopy is a procedure that allows the health care provider to look for blockage in the lower test urologia prostata tract. A cystoscope is a tubelike instrument used to look inside the urethra and bladder. After a solution numbs the inside of the penis, test urologia prostata health care provider inserts the cystoscope through the opening at the tip of the penis and into the lower urinary tract. By looking through the cystoscope, the health care provider can determine the location test urologia prostata degree of the urine blockage.

The procedure is usually performed by a urologist, a doctor who specializes in treating problems of the urinary tract and test urologia prostata male reproductive system. Ultrasound uses a device, called a transducer, that bounces safe, painless sound waves off organs to create an image of their structure. The transducer can be moved to different angles to make it possible to examine different organs.

The gel allows the transducer to glide easily, and it improves the transmission of test urologia prostata signals. Anesthesia is not needed. An abdominal ultrasound can create images of the entire urinary tract. The images can show damage or abnormalities in the urinary tract resulting from urine blockage at the prostate.

Transrectal ultrasound is most often used to examine the prostate. The ultrasound image shows the size of the prostate and any abnormal-looking areas, such as tumors. Transrectal ultrasound cannot definitively identify prostate cancer.

To determine whether a tumor is cancerous, the health care provider uses the transducer and ultrasound images to guide a needle to the tumor. The needle is then used to remove a few pieces of prostate tissue for examination with a microscope.

This process, called biopsy, can reveal whether prostate cancer is present. The biopsied prostate tissue is examined in a laboratory by a pathologist—a doctor who specializes in diagnosing diseases. The MRI machines use radio waves and magnets to produce detailed pictures. An MRI may also involve the injection of dye. A CT scan uses a combination of x-rays and computer technology to create three-dimensional 3-D images. A CT scan may also involve the injection of a dye.

MRI and CT scan images can help identify abnormal structures in the urinary tract, test urologia prostata they cannot distinguish between cancerous tumors and noncancerous prostate enlargement.

Once a biopsy has confirmed cancer, these imaging techniques will show how far the cancer has spread. MRIs and CT scans are usually performed at an outpatient center or hospital by a specially trained technician and interpreted by a radiologist; anesthesia is not needed. For an MRI, light sedation may be used for people with a fear of confined spaces. Urodynamic tests and cystoscopy may cause mild discomfort for a few hours after the procedures.

Drinking an 8-ounce glass of water every half-hour for 2 hours may help reduce discomfort. The health care provider may recommend taking a warm bath or holding a warm, damp washcloth over the urethral opening to relieve discomfort.

A prostate biopsy may produce pain in the area of the rectum and the perineum, which is between the rectum and the scrotum.

A prostate biopsy may also produce blood in urine and semen. Results for simple medical tests such as some urodynamic tests, cystoscopy, and abdominal ultrasound are often available soon after the test. The results of test urologia prostata medical tests such as PSA blood test and test urologia prostata tissue biopsy may take several days to come back. A health care provider test urologia prostata talk with the patient about the results and possible treatments for the problem.

Eating, diet, and nutrition have not been test urologia prostata to play a role in causing or preventing prostate problems. Clinical trials are part of clinical research and at the heart of all medical advances. Clinical trials look at new ways to prevent, detect, or treat disease. Researchers also use clinical trials to look at other aspects of care, such as improving the quality of life for people with chronic illnesses.

Find out if clinical trials are right for you. Clinical trials that are currently open and are recruiting can be viewed at www. The NIDDK translates and disseminates research findings through its clearinghouses and education programs to increase knowledge and understanding about health and disease among patients, health professionals, and the public.
