What is adenoma of the kidney?

Kidney is a paired organ of the person responsible in the body for filtering and performing the excretory function. Often kidneys are susceptible to some diseases. Quite common kidney tumors. Among all benign tumors of the renal parenchyma adenoma of the kidney occurs in 5-9 % of cases. This type of benign tumor is the most common. Most often, this pathology occurs in people after age 40, especially men. This education is growing rather slowly.


The reasons for the development of an adenoma of the kidney remain unknown. Adenoma is morphologically similar to renal cell cancer with a high degree of differentiation. Because according to some assumptions is education consider the initial-stage renal adenocarcinoma.

Adenoma larger than 3 cm may be considered as malignancy. It was also noted that the risk of the incidence of adenoma of the kidney is increased in smokers. Male gender also indicates the risk of adenoma of the kidney. Especially with age increases the risk.

Symptoms of pathology

When the tumor begins to grow and develop, the patient experiences the following symptoms of adenoma of the kidney:

  • hematuria (blood in urine);
  • high blood pressure;
  • pain in the loin resembling renal colic;
  • in some cases, with a significant size of the adenoma, it puts pressure on the ureter and other organs, resulting in its symptomatology resembles the symptoms of a malignant tumor;
  • men expanding the lumen of veins in the spermatic cord.

In case of such symptoms the patient should be mandatory to pass the examination.

The diagnosis of the tumor

With the large size of the tumor can be used to diagnose even if ordinary palpation. For accurate diagnosis of the disease, angiography and computed tomography. These survey methods allow one to accurately identify the kidney tumor.

When conducting a microscopic examination of the tumor adenoma is very similar to nizkotemperaturnoi Oncology.

The treatment of the disease

So often the patient is recommended to begin treatment of the adenoma of the kidney immediately after its diagnosis. Some doctors insist on the observation of renal adenomas, if they are characterized by slow growth and have dimensions up to 3 cm in diameter. If the tumor is large, then its removal is not even discussed. There is a real risk that the tumor has a malignant nature, and it will begin to metastasize.

There are two options removal of the adenoma. The decision about the choice of method of removal takes into account the health of the patient and stage of tumor development. It can be removed by laparoscopy, in which there is minimal injury of the tissues. Other options of surgery for adenoma of the kidney is the classical surgery with a large incision in the lumbar region.

Depending on histologic examination and its results, the patient can recommend resection of the kidney (partial removal of kidney tissue) or nephrectomy (full kidney removal).


Forecast with small size andbenign course of the disease is favourable for the patient. Adenoma does not affect the functioning of the kidneys. It can only compress nearby tissues and structures when reaching large sizes. However, the quality of education not creating threats to the life of the patient.
Otherwise, if the tumor has had time to degenerate into malignant, the value nature of this tumor, its rate of growth and ability to metastasize. It can carry the risk of death for the patient. Important is the timely initiation of treatment, after which five-year survival rate is on average 53 % and ten-year survival rate of 43 %. Latest treatments for kidney cancer (e.g., targeted therapy) improve survival rates of patients with kidney cancer.
