Transrectal ultrasonography

Transrectal ultrasonography (TRUS) is a medical imaging technique that uses ultrasound technology to visualize the prostate gland and surrounding tissues through the rectum. It is primarily employed in the diagnosis and management of prostate-related conditions, including benign prostatic hyperplasia (BPH), prostate cancer, and other abnormalities of the prostate. During a TRUS exam, a small, lubricated ultrasound probe is inserted into the rectum.
