Description
Radiology
Sample Required:
TRUS does not require any specific sample collection. It is a non-invasive imaging procedure that uses sound waves to create images of the prostate gland or other pelvic organs.
Test Time:
The test typically takes about 15 to 30 minutes to complete.
Test Normal Range:
TRUS is a diagnostic imaging test, and there is no specific normal range. The results will depend on the purpose of the examination and what the doctor is looking for.
What is the test?
Transrectal Ultrasound (TRUS) is a medical imaging technique that uses high-frequency sound waves to create detailed images of the prostate gland and surrounding pelvic structures. It is commonly used to evaluate the prostate for conditions such as prostate cancer, benign prostatic hyperplasia (BPH), infections, and abnormalities.
Test Procedure:
During a TRUS, the patient lies on their side with their knees drawn up towards their chest. A lubricated ultrasound probe is gently inserted into the rectum. The probe emits sound waves, which bounce back to create real-time images of the prostate and nearby tissues on a computer screen. The procedure is generally well-tolerated and causes minimal discomfort.
When to take the test?
A doctor may recommend a TRUS if there are symptoms or concerns related to the prostate, such as difficulty urinating, frequent urination, blood in the urine, or abnormal findings on a routine digital rectal examination (DRE). TRUS is also used to guide prostate biopsies and assess the stage of prostate cancer.
Who should take this test?
TRUS is often recommended for men with suspected prostate issues, such as prostate enlargement or prostate cancer. It is commonly used as a part of prostate cancer screening and diagnosis.
Precautions for exceptional cases (pregnancy, etc.):
TRUS is not performed during pregnancy, as it is an imaging procedure specifically for evaluating the prostate and pelvic organs. If you are pregnant or have certain medical conditions, inform your healthcare provider before undergoing the test.
FAQs for Transrectal Ultrasound (TRUS):
Q1: Is TRUS painful?
A: Most people find TRUS to be discomforting rather than painful. The procedure involves inserting a probe into the rectum, which may cause some pressure or mild discomfort. However, it is generally well-tolerated and does not require anesthesia.
Q2: How should I prepare for a TRUS?
A: Before a TRUS, the doctor may recommend an enema to empty the rectum and lower colon. You may also be asked to avoid eating and drinking for a few hours before the procedure. Follow your doctor’s instructions carefully.
Q3: Can TRUS diagnose prostate cancer?
A: TRUS is a valuable tool for evaluating the prostate and guiding biopsies. However, it alone cannot definitively diagnose prostate cancer. If suspicious areas are identified during TRUS, a biopsy may be performed to obtain tissue samples for further analysis.
Q4: Are there any risks associated with TRUS?
A: TRUS is considered safe, and complications are rare. However, as with any medical procedure, there is a slight risk of infection or bleeding. Your doctor will discuss potential risks and benefits before the test.
Q5: Is TRUS the same as a prostate biopsy?
A: TRUS is used to guide prostate biopsies. During TRUS, the doctor can visualize the prostate gland and direct the biopsy needle to collect tissue samples for further examination. The biopsy itself involves taking small samples of the prostate tissue for analysis.
