Transrectal Ultrasound

Meaning

Transrectal ultrasound (TRUS) is a specialized medical imaging technique utilized in clinical practice, primarily for detailed visualization and assessment of the prostate gland and surrounding pelvic structures in men. The procedure involves inserting a small ultrasound probe into the rectum, which allows for high-resolution, close-proximity imaging of the prostate tissue. Clinically, TRUS is an essential tool for diagnosing and staging prostate cancer, evaluating benign prostatic hyperplasia, and guiding targeted biopsies. It provides anatomical detail that is crucial for diagnostic accuracy and subsequent therapeutic planning.
