Prostate Ultrasound (TRUS): Purpose, Procedure, and Clinical Uses

A transrectal ultrasound (TRUS) uses sound waves to image the prostate and surrounding structures. Key uses:

1. Prostate cancer screening – identifies suspicious areas for biopsy.
2. Biopsy guidance – ensures accurate needle placement.
3. Benign prostatic hyperplasia (BPH) evaluation – assesses size, shape, structure.
4. Prostatitis diagnosis – detects swelling, infection, growths.
5. Urinary tract obstruction assessment – identifies urethral narrowing.
6. Treatment monitoring – tracks response to cancer or BPH therapy.
7. Infection/abscess detection – finds prostate abscesses.

TRUS is typically combined with other tests and clinical evaluation for accurate diagnosis.
