How is a benign kidney tumor manifested and treated?
A benign kidney tumor is a tumor that differs from a malignant process in that such a pathology does not cause metastases, slowly increases in size and only in exceptional cases causes a malfunctioning organ.
Most tumors are diagnosed completely by accident because of symptomatic poverty. It does not carry the immediate threat of life, but there is always the risk of its transformation into kidney cancer. In connection with this, conducting diagnostics is an important stage, and such pathology as an early form of kidney oncology is treated.
Types of pathology
- Kidney adenoma is the most common type of benign tumor in the kidney. As a rule, the adenoma is small and grows slowly. The causes of the development of the disease remain unknown, because the tumor is formed without obvious clinical signs. In rare cases, it grows to large sizes and is able to squeeze blood vessels and ureters - while the symptoms of a benign kidney tumor are similar to manifestations of cancer. When considering a tumor under a microscope, it looks like a low-grade kidney cancer. According to official information, it still applies to benign neoplasms, but many specialists tend to attribute adenoma of the kidney to the early stages of oncology.
- Oncocytoma of the kidney is a benign tumor that does not cause any symptoms. In this neoplasm can greatly expand, and the reasons for its formation remain unexplained. Such a tumor mainly affects the male body and is detected accidentally in the process of conducting various examinations of kidney disorders: ultrasound, computed tomography, and others. Many specialists also consider the oncocyte to be a precancerous condition and are advised to organize a surgical operation.
- Angiomyolipoma - in another way it is called a kidney hamartoma - it is a rarely occurring neoplasm of a tumor character that happens, provoked by genetic mutations in the body. The disease can develop in isolation or when combined with some rare genetic disease, for example, with tuberous sclerosis. Like other types of tumors in the kidney, angiomyolipoma is diagnosed accidentally during other examinations. Treatment is developed taking into account the size, strength of manifestation of clinical symptoms. Also the doctor should take into account the age group of the patient and the presence of additional pathologies. If the size of the tumor remains relatively small, then the patient should find under constant supervision of the doctor and undergo a regular ultrasound examination. When this tumor grows to a large size, operative intervention in the disease process remains the preferred one, and therefore there is a risk of accidental rupture. To remove the tumor, an operation called partial nephrectomy is performed.
- Kidney fibroids are benign tumors that are formed by fibrous tissue. A tumor is usually located on the surface of the kidney or inside it. Occurs such a new formation is rare, but can grow to large sizes.
- Kidney lipoma is a tumor that occurs from adipose tissue and mostly affects middle-aged women. Such a tumor can be converted into an oncology, so after a diagnosis, doctors often recommend surgical intervention.
Diagnosis of pathology
For a complete diagnosis of the disease, the urologist should know even the smallest details of the process flow, and therefore, the diagnosis is carried out according to the method from general to specific in accordance with the following plan:
- General blood and urine tests. Biochemical blood tests.
- Immunological blood tests.
- Ultrasound examination of the abdominal organs.
- Computed tomography for abdominal organs.
- X-ray of the thorax region. It is conducted to study lungs for the presence of metastases, which can be caused by a tumor in the kidney.
- Scintigraphy of the kidneys - in this case the doctor enters into the patient's body a radioactive substance and fixes the process of its excretion.
- X-ray of vessels - angiography.
- Biopsy for tumor neoplasm in the kidney. Biopsy makes it possible to make a final decision on the nature of the tumor and to establish its good quality or malignancy. The examination process is organized under local or general anesthesia.
Treatment of pathology
If a benign tumor in the kidney was detected during the diagnosis, the specialist will not insist on urgent surgical intervention. As a rule, the doctor recommends that a constant monitoring of the development of the pathology process and tumor growth take place. But such indications are possible only under conditions that the tumor is single, and its size does not exceed 3 - 5 cm in diameter.
Follow-up refers to the periodic carrying out of ultrasound examination and computed tomography. In accordance with the indications, a resection of the kidney can be appointed - that is, excision of the affected part of the organ. Resection can be performed by traditional methods due to a cut in the lumbar zone, as well as by a laparoscopic method. After the end of the operation, the treatment of a benign kidney tumor continues with the prescription of anesthetic antibiotics to the patient, and after ten days, the sutures are removed.
With the development of a benign tumor, resection is performed, and not removal of the kidney. Resection is the removal of only the affected area of the organ. If a benign tumor was diagnosed and the doctor suggests a complete removal of the organ, you should think about visiting another medical institution and conducting additional research.
But there are also situations in which it is impossible to do without removing the organ. But still, in most cases, the formation of a benign tumor involves the preservation of organs.
