What are the kidney metastases and the causes of their appearance

Kidney metastases occur in tumors that can produce common metastases, namely, bronchogenic cancer, melanoma, or various forms of lymphoma.

Sometimes metastases are formed not only in the parenchyma, but also in its pelvis. Also metastasis of the kidneys is noted with oncology of the larynx or pharynx, breast cancer, adrenal oncology, liver, stomach or pancreatic oncology, esophagus oncology, thyroid gland.

This is important!

In 34% of the kidney is affected by metastases with adrenal oncology, in 18% - with oncology of the lungs, in 11% - with oncology of the opposite kidney. Metastases come through direct interaction, through lymph or through the aortic system.

It can be said that metastases penetrate relatively often, but the work of the organ is disrupted only in exceptional cases. Sometimes a lot of metastases at the gates of the kidney squeeze the ureter and provoke the formation of hydronephrosis and increased blood pressure.

Causes of formation and variety of metastases

Often oncology gives metastases to distant organs - this happens in about 20 - 50% of cases. Renal tumors can grow into a vein of the organ or into the hollow lower vein, and this germination is identified in 15% of the cases of malignant neoplasm in the kidney. But such ingrowth does not indicate the presence of metastases in the kidney, because according to observations of specialists it was recorded that the spread of the tumor thrombus did not provoke any metastases.

The reason for the appearance of the disease is its greater connection of its venous system with the main trunk vessels of the thoracic and abdominal parts.as well as with the veins of the bone system.

If a disease is found, the main reason for this process is fork reflux. It is they who are given the main role in metastasis. Thus, the neoplasm can sprout into the pelvis and disrupt the integrity of the capsule in which the tumor is located. Such renal-reflux reflux can also develop with a minimal increase in the pressure indices inside the renal pelvis, because simultaneously all the pathways are opened for the passive penetration of the smallest particles of the tumor tissue into the venous system of the human body.

The described spread of metastases to the circulatory and lymphatic system most often occurs with papillary cancer of the renal pelvis. In any situation, metastasis occurs too often, in this connection, the patient must constantly be under the supervision of a doctor, the passage of special procedures and the delivery of tests. The doctor helps to choose the optimal treatment and, if necessary, prescribes the operation.

Diagnostics and treatment of

Currently, the following methods are being implemented to conduct a study of the kidneys for the presence of metastases in them:

1. Ultrasonic examination of the kidneys or ultrasound sonography. The advantage of this method is that it is very informative, does not involve invasive intervention, is safe and accessible at its cost. Due to ultrasound, it is possible to assess the state of the renal vein and the lower hollow vein, to establish the presence of metastases.
2. Biopsy - is an intravital fence of a tumor tissue site for research.
3. Computed tomography is a process of layer-by-layer examination of tissues and organs. This is a more accurate method in comparison with ultrasound diagnostics, but also more expensive. This provides information on the size of the tumor, its distribution, the state of the lymph nodes, the state of the renal vein and the inferior vena cava.
4. MRI is a radiodiagnosis with radio beams that does not cause any harm to health.
5. X-ray examination.

The tactics of treatment is usually developed by a doctor oncologist - this primarily depends on the location of the tumor and the history of the patient's illness. To treat metastases in the kidney, as a rule, a set of methods of conservative therapy and surgical intervention. The operation makes it possible to significantly prolong the life of patients.

There are several types of surgical operations:

• Radical nephrectomy is the process of removing the organ together with the adrenal gland, regional lymph nodes and fatty tissue.
• Extended nephrectomy - additional removal of tumor neoplasms of other organs is additionally carried out.
• Kidney resection - performed with mild lesion.

This is important!

The effectiveness of chemotherapy and radiation therapy in the formation of metastases in the kidney does not give the expected results and is used mainly as a palliative treatment to stop the proliferation of foci of pathology and to stop the spread of infection. Thus, the methods of treatment of metastases in the kidneys are sharply limited.

The risk of formation of metastases is almost complete preservation of the normal functioning of the organ, that is, there is no symptomatology, therefore it is impossible to develop and methods of prevention. Diagnosis is made randomly. In connection with what is wasted a lot of time.
