A Key Imaging Tool for Prostate and Pelvic Health

When it comes to evaluating the prostate gland and nearby structures, accuracy matters. Transrectal ultrasound (TRUS – 경직장 전립선 초음파 검사 / gyeongjikjang jeollipseon choumpa geomsa) is a minimally invasive and highly effective imaging test that provides real-time, detailed visuals of the prostate, often used in diagnosing prostate enlargement, cancer, inflammation, or structural abnormalities. At clinics like Gangnam J Urology Clinic, TRUS is conducted with discretion, advanced technology, and patient comfort in mind—making it a valuable diagnostic option for men seeking clarity on prostate or urinary concerns.

What Is a Transrectal Ultrasound?

A transrectal ultrasound is a diagnostic procedure where a small ultrasound probe is inserted into the rectum to obtain clear, high-resolution images of the prostate, seminal vesicles, and nearby tissues. This close approach allows doctors to accurately assess the size, texture, and abnormalities of the prostate gland, which lies just in front of the rectum.

TRUS is commonly used to:

• Evaluate prostate enlargement (BPH)
• Investigate elevated PSA levels
• Guide prostate biopsies
• Diagnose prostatitis or abscesses
• Detect or monitor prostate cancer

Who Needs a TRUS?

• Men with abnormal PSA levels
• Individuals with urinary symptoms like weak flow or frequent urination
• Patients being evaluated for prostate cancer
• Those undergoing fertility assessments involving the seminal vesicles
• Men with chronic pelvic pain or suspected structural issues

How Is TRUS Performed?

 1. Pre-Test Preparation

• A small enema may be recommended before the test
• You’ll be asked to lie on your side in a relaxed position

 2. Probe Insertion

• A lubricated, finger-sized ultrasound probe is gently inserted into the rectum
• Most patients experience mild pressure but no pain

 3. Imaging

• Real-time ultrasound waves create detailed images of the prostate
• The test typically takes 10–15 minutes

 4. Optional Biopsy

• If suspicious areas are found, TRUS can guide needle biopsies during the same session (under local anesthesia)

 5. Post-Test Guidance

• You can return to normal activities immediately unless a biopsy was performed
