Kidney tumor Mixed

Mixed (or complex) kidney tumor is a diagnosis used to describe tumors in the kidney that have a combination of malignant and benign cells or a combination of different types of tumors. This term is used in the context of clinical medicine and implies that both its malignancy and the type of neoplasm will be taken into account when examining and subsequently treating a tumor.

Kidney tumors are quite rare diseases, occupying 4-7 place in the structure of oncological pathology in children. Their frequency of occurrence is about 1 case per 20-30 thousand children. Malignant kidney tumors in children account for 75-80% of all malignant tumors of these organs. They occur more often in girls than in boys in a ratio of 4:1.

To treat kidney tumors, a comprehensive approach is used, including surgery, radiation, chemotherapy and other treatment methods. From time to time, new treatment methods and techniques are used, such as tumor chemoembolization, kidney tumor cryoablation, and interventional therapy.



Mixed kidney tumor (Latin: Tumor renis Mixtus, TM) is a collective concept that unites a group of malignant kidney tumors that do not meet the criteria of any of the alternative TNM criteria adopted for kidney cancer. It is one of the rarest forms of cancer in adults (3–4% of all cases of kidney cancer), and is characterized by the worst survival rates.



Mixed kidney tumor is a rare and serious disease that requires an integrated approach to treatment. This form of tumor occurs when multiple changes in the kidney tissue make it difficult for the organ to function normally.

Symptoms of a mixed kidney tumor may vary depending on its size and location. However, the most common symptoms that appear are:

- Pain in the lumbar region, which may occur periodically or constantly; - Increased blood pressure; - Change in urine color (urine may be red, brown or bloody); - Presence of blood in the urine; - Increase in the size of the kidney (usually observed with large tumors).

To determine an accurate diagnosis, it is necessary to conduct a number of studies and tests, including endoscopic and x-ray examinations, computed tomography and others. In addition, treatment of this form of tumor may require surgery to remove affected tissues and organs.

Treatment of mixed kidney tumor is based on the use of medications, surgery, chemotherapy and other methods aimed at reducing the growth of the tumor and preventing its recurrence. In each case, individual treatment is prescribed, so consultation with a specialist is necessary. It is important to note that a mixed tumor can lead to serious consequences, such as urinary retention, kidney failure, urinary tract infection and dysfunction of other organs. Therefore, if symptoms appear, you must consult a doctor for timely treatment.

In conclusion, it is important to note that kidney tumor prevention is one of the main ways to reduce the risk of the disease. Regular medical examinations and adherence to healthy lifestyle rules (healthy eating, physical activity, quitting smoking and drinking alcohol) can reduce the likelihood of tumors and other diseases.



Kidney tumors are neoplasms of kidney tissue and its various elements, emanating from kidney cells, but consisting not only of kidney tissue - parenchyma.

The tumor process of such cells is rare; in most cases, their development into the kidneys is accompanied by hydronephrosis - stretching of the renal capsule with blood when the passage of urine is impaired or the formation of secondary cysts
