Symptoms, treatment and causes of a tumor in the kidney

  • Symptoms, treatment and causes of a tumor in the kidney

    Currently, approximately 90% of all tumors in the kidneys are accounted for by renal cell carcinoma. Often, the tumor is bilateral, but sometimes the second kidney is affected somewhat later than the first.

    Causes of a tumor can be varied, but mostly doctors can not identify the exact etiological factors.

    Causes and manifestations of

    pathology It is difficult to accurately establish the causes of kidney cancer. There is evidence that the risk of developing pathology increases in people working on the production of aniline dyes, so some of their components are accused of carcinogenic effects.

    With a small tumor size, the cancer can flow without external manifestations. Developing symptomatology is often characterized by its diversity and is classified into renal and extrarenal features.

    The renal symptoms of oncology include: the presence of blood in the urine, pain in the lumbar region and a palpable tumor from the affected side. Simultaneous formation of all signs characterizes the presence of a large tumor and neglect of the process. In the early stages of pathology, one or two signs appear.

    The appearance of blood in the urine with kidney cancer is manifested unexpectedly, it is not accompanied by painful sensations, deterioration of general well-being. Macrogematuria occurs due to injury of blood vessels due to the germination of the neoplasm in the kidney parenchyma. A pronounced hematuria can provoke anemia, cause kidney colic, tamponade in the bladder and acute urinary retention.

    Pain sensations on the affected side are considered a late symptom of oncology. Pain, as a rule, is dull, aching and arises from the pressure on the nerve endings with the growth of the tumor and the dilatation of the capsule of the organ. Tumor is felt only in the third or fourth stage of development.

    As for extrarenal signs of kidney cancer, they include: lack of appetite, weakness, weight loss, severe sweating, high fever and high blood pressure, swelling of the legs, thrombosis in the veins of the lower limbs, liver dysfunction.

    The increase in temperature in oncology is of a long-term nature and persists at subfebrile elevations, but at times it rises to a high level. In the early stages, the increase in temperature is explained by the reaction of immunity to tumor antigens, and in the later stages - by the inflammatory process and necrosis.

    The diverse clinical signs of oncology can be a manifestation of metastasis of the neoplasm in nearby tissues and other organs. Symptoms of metastasis are: expectoration of blood, cough, pain, pathological fractures, severe head pain, increased neurological manifestations, brain damage, jaundice.

    In children, oncology of the kidneys is manifested by an increase in the size of the kidney, high fatigue, weight loss and various pains.

    Treatment of pathology

    Surgical treatment is the main and most effective method of treatment in the development of kidney cancer. This method is also used for regional and distant metastases and makes it possible to improve the quality and life span of patients.

    With oncology, this organ is removed - nephrectomy, or resection - excision. Selection of the therapeutic approach depends on the pathology, the size of the tumor and the location of the tumor. Also, survival depends on these factors.

    Resection of the kidney is organized to preserve the organ in patients suffering from a local form of oncology, provided that the tumor size does not exceed 4 cm. Also, resection is indicated in the bilateral process of tumor development, if the second kidney is disturbed. In the process of resection, samples are taken at the same time for histological examination from the edges of the wound to establish the depth of the tumor lesion. After resection, the risk of local tumor re-formation is markedly reduced.
