Anechogenous formation in the kidney: causes, symptoms and features of treatment

What is anechogenous formation in the kidney? It does not contain liquid. Typically, this inclusion is a cyst. To determine the exact pathology, additional diagnostic procedures are necessary. In this case, methods that have a high degree of accuracy are used. For example, if an ultrasound examination revealed a spot in the upper part of the organ, this could be evidence of a cyst not only in the kidney, but also in the liver, diaphragm, or spleen.

If the stain was located near the kidney, then, as a rule, it is a sign of a hematoma. Sometimes pathology is accompanied by bleeding in the cyst. This phenomenon serves as a symptom of the presence of cystic cancer.

Abnormal formation of large size

The formation of a large size in the left or right kidney is often detected on ultrasound. As a rule, it is a benign tumor.

Usually anechogenous avascular formation in the kidney has clear, rounded contours.

Pathological inclusions can be quite large, have irregular contours and difficult to define boundaries. In complex objects, bleeding, abscess, necrosis or calcification may be detected.

If the formation has a size of up to 30 mm, this may be evidence of the presence of carcinoma of the kidney, adenoma or oncocytoma. In addition, a pseudotumor can develop.

Sometimes metastases can be traced. Often formed angiomyolipoma or a small cyst. The cause of cyst development is polycystosis and structural changes in the cortical layer.

Symptomatics

The presence of simple cysts in the kidneys is evidence of a benign neoplasm. Often they are traced in ultrasound, which is carried out in the diagnosis of a very different disease. Since in this pathology the symptoms are worn-out, in most cases the disease does not manifest itself. The cyst itself in this case does not require therapy.

But if anehogenous formation in the left kidney or right has reached impressive sizes, then the symptomatology can be the following:

• Dull pain in the lumbar region, abdomen or sides;
• fever;
• The appearance of the urine in the urine (hematuria);
• Violation of urination due to the pressure of the cyst on the pelvis ;
• nausea;
• General weakness.

Form of cystic neoplasm

In their form, cysts are simple and complex. They are also single and multiple, located in the cortical or brain tissue of the kidney (cysts of the parenchyma), congenital and acquired.

The causes of the acquired anomaly

The cause of the acquired anomaly are processes of an infectious nature, passing in the kidneys or the urinary system.

When examining by ultrasound in this pathology, thin-walled spots of circular shape of different size and clear contours are detected. At the first stages of the disease, they have a small form. At a late stage can reach 3 cm and above, which poses a threat to health.

Are small inclusions dangerous?

Anehogen formation in a small kidney does not pose a threat to the life of the patient. It is evidence of minor inflammatory processes. This condition is stopped with proper treatment.

Varieties of large cysts

Among large size cysts, the following varieties should be distinguished:

• Solitary. It has a rounded shape, does not include constrictions and connecting ducts, which are filled with serous fluid. It often includes blood and purulent veins.
• Polycystic. It affects most of both kidneys.
• Multi-cystic. It develops in the kidney or brain substance in the spongy kidney.
• Dermoid. It is characterized by the presence of various inclusions: hair, pieces of skin, fatty layer, etc.

When carrying out ultrasound, benign lesions appear as single or multiple. They look like big spots. However, the structure of the kidney parenchyma is not changed.

Secondary benign tumor on the monitor of the ultrasound device is depicted as a neoplasm with uneven contours around the tissue scars. It has a modified internal ehostruktura.

Anehogenous formation in a large kidney may indicate the presence of cancer of the kidney, adenoma or other types of tumors.

Kist caused by echinococci

It happens that the anomaly is caused by the presence of internal parasites. The cyst, provoked by echinococci, has an uneven thickened structure with the presence of internal membranes and partitions. Such education in medicine was called "floating lily".

How is the abscess manifested?

The accumulation of purulent contents is expressed in spots of circular shape, the edges of which do not differ evenly. The walls of the neoplasm are thickened. A dark highlight located around the kidneys is a sign of a possible hematoma or cancerous tumor.

Polycystic kidney disease

Why there are multiple anehogenous formations in the kidneys? The causes should be sought in the genetic factor. Along with the hereditary mechanism, there are cases of the emergence of pathology against the background of nephrotoxic effects of drugs that are taken during pregnancy.

How is carcinoma manifested?

Carcinoma has uneven outlines without capsules, which is a sign of a negative mass structure. Often visualized pseudocapsule, which is formed by a compressed parenchyma around a cancerous tumor. Growing up, an oncological neoplasm extends beyond the silhouette of the kidney.

Stains of white color with even rounded forms without malignant inclusion indicate the presence of sand or stones, and shadow paths - about the presence of gases or accumulation of calcium salts.

How are metastases manifested?

Metastases reflect sound. They have different shapes and sizes. The main area of their localization is the root part of the kidneys.

What else can capture ultrasound images?

A dark highlight near the kidneys that has the right contours is a possible consequence of hemorrhage, in which anehogenous formation in the parenchyma of the kidney is indicated. When the bleeding area becomes more extensive. When the blood coagulates, the new formation does not reflect the sound wave.

Dark contours can be a sign of a prolonged inflammatory process, which is accompanied by a build-up of pus.

This can lead to such complications as:

• Ruptured cysts with extensive bleeding;
• Compression of the parenchyma of the kidney, which disrupts the functionality of the organ;
• Nephropathy.

Complications

Often anehogennoe education in the sinus of the kidney can provoke serious complications. Anomaly can become a trigger mechanism for the development of the infectious process, which is accompanied by fever, rising temperature and increased pain.

There may also be a rupture of the cyst, which is accompanied by acute pain in the back or side region. There is a violation of urination, which leads to edema of the kidney (hydronephrosis).

The presence of multiple cysts is fraught with serious complications. Polycystic can provoke a partial or complete atrophy of the organ, which leads to kidney failure.

Methods of diagnosis

To identify such a pathology as anehogenous formation in the kidney, the following methods are used:

• Ultrasound with the use of diuretics;
• Ultrasound dopplerography of kidney vessels ;
• Nephroscintigraphy;
• Computed tomography with contrast rays;
• Analysis of blood and urine;
• Taking of cells for sowing (cytological examination is carried out in exceptional cases).

Comprehensively diagnosis is the guarantee of proper therapy. The anhenogenous formation found in ultrasound should be differentiated with a malignant tumor or cystic cell carcinoma of the kidney.

Treatment of ahenogenous inclusions

Most cystic lesions, which are not accompanied by a change in the structure of the tissues and do not cause hemorrhages and difficulty urinating, do not need special treatment. However, the infectious process requires close monitoring by specialists. To this end, it is recommended to undergo an ultrasound examination twice a year and take blood and urine for analysis.

If the neoplasm provokes the appearance of complications such as pyelonephritis of various types, kidney stones, elevation of blood pressure, the patient is immediately treated.

How is anechoic kidney formation eliminated? Treatment is carried out depending on the size and extent of the inflammatory process. A specialist can be suggested to remove the contents of the cyst by means of a puncture followed by drainage. In some cases, resort to surgery.

A high level of effectiveness is provided by laparoscopy. Removal of the cyst requires the subsequent medical treatment, as well as the intake of vitamins and minerals, which have antibacterial effects and strengthen the immune system. Also, the function of the kidneys and blood vessels is normalized.

The earlier the therapy was started, the sooner the recovery will come.

How to prevent development of anechogenous formations in the kidneys?

To prevent the development of cysts the following measures will help:

• healthy lifestyle;
• balanced diet;
• rejection of bad habits;
• Timely treatment of infectious diseases;
• Preventive examinations at the doctor.

Conclusion

Anehogenous formation in the kidney is diagnosed by ultrasound. It is an anomaly that does not react to sound. As a rule, this cystic enlargement. Anomaly can be either benign or malignant. A wide range of additional diagnostic methods are used to establish an accurate diagnosis.

A cyst of small size, as a rule, does not pose a threat to the human body. Large size neoplasm should alert. Often it is a malignant tumor (carcinoma).
