How to interpret transrectal ultrasounds: 3 key methods
Transrectal ultrasound (TRUS) is an imaging technique that uses sound waves to create images of the prostate and surrounding tissues. This guide explains what a TRUS can reveal, why it's used, and how to understand its findings.
What is a Transrectal Ultrasound?
A TRUS is a minimally invasive imaging test where a small probe is inserted into the rectum to produce real-time images of the prostate, seminal vesicles, and nearby structures. Unlike X-rays, TRUS uses sound waves, making it safe and painless. Let's explore the details of this technique.
What Can Transrectal Ultrasound Show?
- Prostate Imaging: Detailed views of the prostate gland, including size, shape, and any abnormalities.
- Seminal Vesicle Evaluation: Assessment of the seminal vesicles for issues like cysts or inflammation.
- Detection of Prostate Cancer: Helps in identifying suspicious areas that may require further investigation, like biopsies.
- Guidance for Biopsies: TRUS is commonly used to guide prostate biopsies, ensuring accurate sample collection.
- Monitoring Prostate Health: Useful for tracking the progression of prostate conditions and the effectiveness of treatments.
Why Might You Need a Transrectal Ultrasound?
- Elevated PSA Levels: When blood tests show high levels of prostate-specific antigen (PSA), TRUS can help to understand the reason for this.
- Abnormal Digital Rectal Exam (DRE): To investigate any abnormalities felt during a physical exam of the prostate.
- Urinary Symptoms: In cases of urinary issues or suspected prostate enlargement.
- Prostate Cancer Monitoring: Follow up and staging in patients with diagnosed prostate cancer.
- Infertility Evaluation: Assessment of the seminal vesicles as part of an infertility workup.
How is a Transrectal Ultrasound Performed?
The TRUS procedure is relatively straightforward and typically performed in a doctor's office or clinic. Here's a step-by-step overview:
- Preparation: You may be asked to empty your bladder before the procedure. In some cases, an enema may be recommended.
- Positioning: You'll be asked to lie on your side, usually with your knees bent towards your chest.
- Probe Insertion: A small, lubricated ultrasound probe is gently inserted into your rectum. The probe is about the size of a finger.
- Imaging: The probe emits sound waves to create images of the prostate gland and surrounding tissues on a monitor.
- Procedure Completion: Once the images have been obtained, the probe is carefully removed. The procedure typically takes between 10 to 30 minutes.
The procedure is usually well-tolerated, and most patients experience minimal discomfort. You can typically resume normal activities immediately after the TRUS.
