Transrectal ultrasonography (TRUS) is an imaging technique that utilizes sound waves to create images of the rectum and nearby structures. It is most commonly used in men to examine the prostate and seminal vesicles, particularly when a doctor suspects conditions like prostate cancer, benign prostatic hyperplasia (BPH), or prostatitis. It can also help guide a biopsy of the prostate when needed.
The procedure involves the insertion of a small, lubricated probe called a transducer into the rectum. This transducer emits sound waves that bounce back after hitting various tissues. These echoes are transformed into images displayed on a screen, providing a detailed picture of the rectal area.
Transrectal ultrasonography has the advantage of offering a closer and more detailed view of the prostate than a transabdominal ultrasound. It can identify areas of abnormal tissue, measure the size of the prostate, help in staging prostate cancer, and guide treatments like radiation therapy.
Preparation: You may be asked to use an enema to clean your rectum before the procedure. The doctor or nurse will give you specific instructions about when and how to use it.
Clothing: Wear loose, comfortable clothing that can be easily removed as you may need to change into a hospital gown.
Allergies: Inform your doctor if you have any known allergies, especially to latex or lubricating gel.
Medications: If you are on medications like blood thinners, discuss it with your doctor as you may need to stop these temporarily.

Transrectal Ultrasonography (TRUS) is an imaging procedure where a small probe, or transducer, is inserted into the rectum to create images of the prostate and nearby structures. It is commonly used to identify and evaluate conditions affecting the prostate.
In TRUS, a small, lubricated transducer is gently inserted into the rectum. The transducer emits sound waves that create echoes when they bounce off different tissues. These echoes are transformed into images displayed on a monitor.
While TRUS might cause some discomfort, it is usually not painful. The probe used is thin, and a lubricating gel is applied to minimize discomfort. If a biopsy is being performed during the procedure, local anesthesia is typically used.
A TRUS procedure usually takes about 10 to 20 minutes, but it may take longer if a biopsy is also being performed.
Yes, TRUS can help detect prostate cancer by identifying areas of abnormal tissue. However, it is often used alongside other tests, such as PSA (prostate-specific antigen) blood tests, to diagnose prostate cancer.
If TRUS shows an area of concern, your doctor may recommend further tests such as a biopsy, where a small sample of tissue is taken from the prostate for examination under a microscope.
TRUS is a safe procedure with minimal risks. However, there can be minor discomfort during the examination, and a small risk of infection if a biopsy is performed.
Before a TRUS, you may be asked to use an enema to clean your rectum. Also, discuss any medications you are taking with your doctor, especially if they are blood thinners.
Typically, the doctor performing the ultrasound will be able to discuss preliminary results with you right after the procedure. However, if a biopsy was done, it might take several days for the laboratory to process and analyze the samples.
No, a TRUS is not the same as a prostate exam. During a routine prostate exam, a doctor physically examines the prostate by inserting a gloved finger into the rectum. In contrast, TRUS uses sound waves to create detailed images of the prostate.
As part of regular health checks, men, especially those over the age of 50 or those with a family history of prostate issues, may be recommended to have a TRUS. This procedure is an invaluable tool for diagnosing and managing prostate conditions. If you have any concerns or questions about TRUS, do not hesitate to discuss them with your doctor.
