What is a prostate ultrasound?

A prostate ultrasound, also called a transrectal ultrasound (TRUS), is a medical procedure that uses sound waves to create images of the prostate gland. It is typically performed to evaluate the prostate for abnormalities, such as enlargement (benign prostatic hyperplasia or BPH), inflammation (prostatitis), or cancer.

During a TRUS, a small ultrasound probe is inserted into the rectum. The probe emits sound waves that bounce off the tissues and organs in the pelvic area, creating images of the prostate gland. These images can be viewed on a monitor and can provide detailed information about the size, shape, and structure of the prostate.

A TRUS may be recommended for several reasons, including:

1. Prostate cancer screening: A TRUS can be used to detect prostate cancer, particularly in men who have an elevated prostate-specific antigen (PSA) level or other risk factors.

2. Diagnosis of prostate conditions: A TRUS can help diagnose conditions such as BPH, prostatitis, or prostate cysts.

3. Evaluation of prostate biopsy results: If a prostate biopsy has shown abnormal cells, a TRUS can be used to guide the biopsy and obtain more tissue samples.

4. Treatment planning: A TRUS can be used to plan treatments for prostate cancer or BPH, such as radiation therapy or surgical removal of the prostate gland.

A TRUS is generally considered a safe procedure with few risks or complications. However, it can cause some discomfort, such as a feeling of pressure in the rectum. In rare cases, it may cause bleeding or infection.

The procedure usually takes about 15-20 minutes, and the results are typically available within a few days. A doctor will interpret the images and discuss the findings with the patient.
