What are the manifestations of prostate cancer in ultrasound examination? Prostate cancer examination items

The number of patients suffering from prostate cancer is increasing. The disease seriously threatens the physical and mental health of male patients. Therefore, male friends must pay great attention to it. Many male friends suspect that they have prostate cancer, but they don’t know how to check it. Let’s take a look at what the experts say.

Ultrasound examination is a non-invasive examination that can detect nodular changes in the prostate at an early stage, which is helpful for early diagnosis of prostate cancer and observation of treatment effects. Commonly used ultrasound examinations include transabdominal, transrectal, and transurethral. Among them, transrectal ultrasound is the most accurate for diagnosing prostate cancer. It can clearly show subtle structural changes in the prostate and can confirm lesions with a diameter of 5 mm. It is the preferred method for diagnosing prostate diseases.

Typical ultrasound findings of prostate cancer are:

(1) The prostate gland becomes enlarged, asymmetrical, and morphologically inconsistent.

(2) The capsule is rough and thickened, the continuous bright lines are interrupted and damaged, and the local layers are unclear.

(3) The internal echo is uneven, and irregular focal hypoechoic areas may appear, accompanied by strong light spots and light clusters, and there may be sound attenuation. The lesions often appear in the posterior lobe or the left and right lateral lobes, and the boundaries between the inner and outer membrane structures are unclear.

(4) Invasion of adjacent tissues: echoes of the mass may be detected in the seminal vesicle, bladder, vesicorectal pouch, or rectal wall, or there may be irregular thickening of the bladder neck that protrudes into the bladder.

(5) Manifestations of lower urinary tract obstruction: Prostate cancer causes obstruction of the bladder neck and posterior urethra, resulting in hydronephrosis. The bladder mucosa shows trabecular changes, and residual urine can be seen.

In addition, under the guidance of B-ultrasound, puncture biopsy can be performed on suspicious space-occupying lesions. It is widely used in clinical practice because of its accurate positioning, simple operation, little pain for patients and few complications. Three-dimensional ultrasound has been used in clinical practice and can display the three-dimensional structure and fine structure of the prostate. It is incomparable to two-dimensional ultrasound in diagnosing prostate cancer.

After the expert’s explanation, I believe everyone clearly knows that ultrasound has many manifestations in prostate cancer examination. Therefore, when male friends feel that they have prostate cancer, they must go to a regular professional andrology hospital for an ultrasound examination to determine their condition and then receive targeted treatment.
