Ultrasound Transrectal

Overview

Ultrasound Transrectal, commonly known as TRUS (Transrectal Ultrasound), is a specialized imaging examination used to obtain detailed images of the prostate gland, seminal vesicles, and surrounding pelvic structures. The examination is performed using a small ultrasound probe inserted into the rectum, allowing high-resolution visualization of the prostate and nearby tissues.

TRUS is commonly recommended for patients with elevated PSA levels, prostate enlargement, urinary symptoms, suspected prostate abnormalities, infertility evaluation, and prostate biopsy guidance. The examination provides valuable diagnostic information while remaining safe and radiation-free.

Benefits of the Test

• Provides detailed visualization of the prostate gland.
• Assesses prostate enlargement and structural abnormalities.
• Evaluates seminal vesicles and adjacent tissues.
• Supports prostate biopsy guidance.
• Helps investigate elevated PSA levels.
• Assists in infertility evaluation.
• Safe and radiation-free examination.
• Provides real-time imaging for accurate assessment.

Why Doctors Recommend This Test

• Evaluation of prostate enlargement.
• Assessment of elevated PSA levels.
• Investigation of urinary symptoms.
• Guidance for prostate biopsy procedures.
• Evaluation of suspected prostate abnormalities.
• Assessment of male infertility.
• Monitoring known prostate conditions.

Preparation Before the Test

• A bowel preparation or rectal cleansing may be advised.
• Follow instructions provided by your doctor.
• Inform the healthcare team about medications and medical history.
• Carry previous reports and PSA test results if available.
• Wear comfortable clothing.
• Follow any dietary instructions provided before the procedure.

Who Should Take This Test?

• Men with elevated PSA levels.
• Patients with enlarged prostate symptoms.
• Individuals with urinary difficulties.
• Patients undergoing prostate biopsy evaluation.
• Men with suspected prostate abnormalities.
• Individuals undergoing infertility assessment.
• Patients requiring detailed prostate imaging.

Normal Reporting Time

Reports are typically available within 2 to 4 hours after completion of the examination and radiologist review.

Detailed Information

Transrectal Ultrasound is one of the most important imaging examinations used in urology. Because the ultrasound probe is positioned close to the prostate gland, it provides highly detailed images that cannot be achieved through standard abdominal ultrasound alone.

The examination allows accurate evaluation of prostate size, shape, internal architecture, calcifications, cysts, nodules, and other abnormalities. It is frequently used when investigating elevated prostate-specific antigen (PSA) levels or abnormal findings during a digital rectal examination.

TRUS is also widely used as a guidance tool during prostate biopsy procedures. Real-time ultrasound imaging helps ensure accurate tissue sampling when evaluating suspicious prostate lesions. In addition, the examination may be used to assess seminal vesicles and support infertility investigations.

Urologists and radiologists frequently recommend transrectal ultrasound because of its diagnostic accuracy and ability to provide detailed assessment of prostate-related disorders. The examination may also be used for monitoring known prostate conditions and evaluating treatment response.

The procedure is generally well tolerated and does not involve radiation exposure. Most examinations take approximately 20 to 30 minutes. Reports are usually available within 2 to 4 hours after interpretation by an experienced radiologist.
