Ultra Sound (USG): Trans-rectal (Trus)

Specimen Required

NONE

Fasting Required

Purpose of the Test

A trans-rectal ultrasound (TRUS) is a diagnostic imaging test that uses sound waves to create images of the prostate gland and surrounding tissues

When this test is required

TRUS may be requested by a healthcare provider if a patient is experiencing symptoms such as difficulty urinating, frequent urination, or blood in the urine. It may also be used as a follow-up to abnormal findings on a routine digital rectal exam or PSA blood test.

What the Test Detects

Trans-rectal ultrasound (TRUS) is a medical imaging technique that uses high-frequency sound waves to produce images of the prostate gland and nearby tissues. It is a type of ultrasound that is performed through the rectum.

Preparation for the Test

It is important to follow the doctor’s instructions and attend the appointment on time. The test is generally safe and well-tolerated, although some patients may experience discomfort or pain during the procedure. Patients may be advised to take over-the-counter pain relievers or apply a warm compress to the rectal area after the test. The results of the test will be interpreted by a doctor and used to guide further diagnosis and treatment.

Sample Requirements

No sample is required for this test, and no special preparation is typically needed. However, patients may be asked to avoid eating or drinking anything for several hours before the test to improve the accuracy of the results. Patients may also need to take a laxative or enema to empty the rectum before the test.

Additional Notes

Before a TRUS procedure, patients may be instructed to avoid eating or drinking for a certain period of time, and may need to undergo a bowel preparation to empty the rectum. Patients should also inform their healthcare provider if they have any medical conditions or take any medications that may affect the procedure. As with any medical procedure, there are some risks associated with TRUS, including infection, bleeding, and discomfort. However, these risks are generally low, and most patients tolerate the procedure well.
