What does prostate ultrasound check?

In hospitals, there are various instruments used to examine the body, such as B-ultrasound, CT, etc. Each instrument has its own function and can help people diagnose various diseases. For men, when they go to the hospital for a physical examination, they often need to check the prostate. So what diseases of the male prostate can be detected by prostate color Doppler ultrasound?

Prostate color Doppler ultrasound is a type of prostate ultrasound examination. Prostate ultrasound is more helpful than X-ray and CT in determining the location, size, shape, and intra-glandular invasion range of prostate cancer. Combined with ultrasound-guided puncture biopsy, it is helpful for the grading and staging of prostate cancer. It can also understand the size of the prostate, the presence or absence of calcification, cysts, space-occupying lesions, etc. Of course, color Doppler ultrasound has a great diagnostic reference value for epididymitis and varicocele. Color Doppler ultrasound is of great significance in determining the clinical diagnosis and treatment of the prostate.

Prostate ultrasound is a routine disease examination method and is suitable for the diagnosis of the following diseases:

Benign prostatic hyperplasia, prostate cancer, prostatitis, prostate abscess, prostate cyst, prostate stones.

Normal values ​​of prostate ultrasound examination:

Normal sonogram of prostate:

The prostate is about 4×3×2cm in size. Its cross section is symmetrical millet-shaped; its longitudinal section is oval, larger at the top and smaller at the bottom. The echo of the prostate capsule is a smooth continuous line, and the gland is evenly distributed with small light spots. A bright light spot from the urethra can be seen in the center of the image.

The ultrasound values ​​of normal prostate may vary depending on the examination route, the type of ultrasound machine, the examination position, and the detection angle.

Measurements via abdominal examination.

1. Measuring sections and parts

1. Transverse section of abdomen;

Width measurement: the maximum diameter from the left edge to the right edge.

Thickness measurement: the maximum diameter from the front edge to the back edge.

2. Measurement of the longitudinal length of the abdomen: the maximum diameter from the upper edge to the lower edge.

2. The average normal value of prostate measurement is: length 3cm, width 4cm, thickness 2cm.

3. Calculation of prostate volume: half the product of the three diameters, i.e. V = l/2.

The seminal vesicle of an adult is a coiled glandular sac or glandular duct, about 6 cm long and 2 cm wide, and it communicates with the vas deferens just below the umbilicus.
