Ultrasound of the prostate allows you to get an idea of its size, shape, structure, as well as the peculiarities of its relationship with other pelvic organs.
Indications for ultrasound of the prostate
- Determination of the size and detection of enlargement of the gland.
- Diagnosis of neoplasms and various diseases.
- Revealing the causes of male infertility.
- Difficulty urinating.
A survey should be prepared. The patient is advised to come in a comfortable and non-cramping dress and make a cleansing enema 2-4 hours before the procedure. The SPL itself takes about 20 minutes. The only limitation of this diagnosis is that it is not performed for patients who have been removed from the rectum as a result of a surgical procedure. The study is carried out in real time, which allows it to be used for various minimally invasive procedures.
Ultrasound signs of prostate pathology
Ultrasound of the prostate allows you to get an idea of its size, shape, structure, as well as the peculiarities of its relationship with other pelvic organs.
You can obtain an ultrasound image of the prostate during a non-invasive examination through the anterior abdominal wall with a filled bladder, as well as with a TRUS. It should be noted that the transabdominal echography of the prostate often only gives an idea of its shape and size. TRUSY is used for a more detailed study of the tissue structure and the determination of blood flow characteristics in dopplerography. The echographically unmodified prostate with frontal scanning is a rounded symmetrical formation, on the sagittal section it is oval, with a clear, even contour and a well differentiated capsule separating the gland from the highly echo paraprostatic fiber. Prostate tissue is uniform, moderately low echomodality. Normally, the gland does not go into the lumen of the bladder.
With frontal scanning, the seminal vesicles are visualized on the sides of the prostate, just beyond its cranial portion. On the echogram they look like echo-negative formations of elongated shape up to 1 cm in diameter.

Prostate adenoma on scans - a uniform formation, different in shape and size, but always with clear, even contours and a well-traced capsule. Adenomatous tissue of the gland can develop unevenly evenly and look asymmetric in frontal echoscanization. With the predominance of glandular elements, the edema of the aroma due to adenoma and the associated inflammatory process of the echogenic gland can be diffusively reduced: in the parenchyma, small anechogenic rounded formations are sometimes found. In the case of chronic inflammation in the parenchyma, hyperechoic inclusions (sometimes with an acoustical path) occur. As a rule, in the transit zone and along the course of the surgical capsule or on the border of the central and peripheral zones.
To determine the causes of obstruction of the lower urinary tract and to assess the structural changes in the urethra, micture ultrasound cystourethroscopy (echrodynamic examination) is used. The essence of the method is transrectal ultrasound of the prostate performed during urination. Passage of urine through the urethra allows you to see the latter during echography, which can not be done when it is asleep. Transrectal echograms at the time of urination determine the neck of the bladder in the form of a funnel with a clear and even inner contour, the prostatic and, in part, the membranous parts of the urethra, about 5 mm thick. If the cause of obstruction is prostate adenoma, the urethra at this site is visualized as a thin anehogenous strip less than 5 mm wide. Deviation of the urethra by adenomatous tissue depends on the form of its growth. Mikational ultrasound cystourethroscopy acquires great importance in the recognition of urethral stricture, especially if the patient has prostate adenoma. It allows to determine the state of the urethra proximal to the site of constriction, localization and, in some cases, the extent of the stricture. During urination, if his impairment is not associated with prostate adenoma. With stricture, dilatation of the urethra is noted above stenosis (including the prostatic section). With inflammatory narrowing, the outline of the urethra is distinct, straight, the diameter of the healthy part of the urethra is not changed.
In addition to diagnosing structural changes in the urethra. Mixed ultrasound cystourethroscopy in combination with UFM or dopplerography of the urine flow allows us to detect functional changes in the urethra and bladder.
IVO in prostate adenoma leads to structural and functional changes in the urinary tract (for example, the bladder). Determining the volume of residual urine by ultrasound is an important method for diagnosing and establishing the stage of prostate adenoma.
Prostate cancer is characterized by echographic features in the form of formation of heterogeneous hypoechoic nodes in the peripheral zone.
Depending on the stage, symmetry breaking, uneven contour and thinning of the capsule are observed. With ultrasound in 13% of observations, cancer nodes have more pronounced echogenicity than the gland tissue, and in 9% they are isoechoic or not detected at all.
Echographic changes in prostatitis depend on the form of inflammation and are extremely diverse. Thus, with acute prostatitis, an increase in the size of the gland and a decrease in its echomodality are noted in both individual sites and in all of the gland. Abscess of the organ is easily diagnosed with transrectal ultrasound. The echographic pattern has characteristic features. The abscess looks like the formation of a rounded or irregular shape of a significantly reduced echogenicity, almost approaching that of a liquid structure (anechogenous character). The structure of the abscess of the prostate is not homogeneous due to the content of purulent-necrotic masses in it; often observed anehogennye (fluid) inclusions. With color Doppler mapping in the abscess area, there is no circulation, and around it a pronounced vasculature is found.
In the chronic inflammatory process in the prostate, without exacerbation, the changes in the structure of the organ, associated with sclerotic changes, come to the forefront, which, when echography, have the form of hyperechoic regions without an acoustic effect. Stones in the prostate look like hyperechoic, often multiple formations with a clear acoustic path. Echodoplurography of the prostate allows you to explore the features of the circulation in it for various diseases, which increases the diagnostic value of the method.
Where to make prostate uzi?
Where to make ultrasound of the prostate gland and what are the main indications for its conduct, we will consider these questions. Ultrasound scanning of the prostate or ultrasonography is a diagnostic method, with which you can identify a number of diseases and pathologies. For the study, a transrectal method is used, that is, the introduction of an ultrasound transducer into the rectum of the patient.
