Parenchyma of the kidney. Definition and common pathologies

Each human kidney is covereda connecting capsule consisting of a specific (intrinsic) tissue, as well as a system for the isolation and accumulation of urine. Specific tissue (a group of cells) consists of a brain and cortical substance. This group of cells formed the parenchyma of the kidney. This specific tissue has the ability to recover.

CT and ultrasound are used to determine the condition, inwhich is the parenchyma of the kidneys. The norm of the thickness of the body's own tissue varies from an average of twenty to twenty-three millimeters. Depends on the average thickness of the tissue from the age of the patient.

Diffuse changes in the renal parenchyma canarise for various reasons. The data do not have an independent value. Among the provoking factors, we should mention the initial stage of the progression of urolithiasis, the formation of plaques in the pyramid region, which later turn into renal concretions (stones).

In addition, changes of this kind can be represented by hyperechoic inclusions and are associated with renal vessels or adipose tissue.

To accurately determine the disease and its stage in such cases, there is a need for a comprehensive survey.

In the structure of their own tissue, the kidneys canTo develop and numerous neoplasms (tumors). In this case, the formation of benign and malignant. Cancer is quite common. This pathology accounts for about 85-90% of all tumorous diseases affecting the kidney parenchyma. Among the characteristics of cancer should be noted a kind of "venotrophy". This condition is characterized by the presence of a thrombus passing through the veins to the main trunk, and then to the inferior vena cava. In some cases, it can reach the atrium.

Significantly less often (in 6-8%) benign neoplasms are revealed. Among them, adenoma, oncotcioma, angiomyolopoma should be considered common.

As a rule, to identify these pathologies apply CT and ultrasound.

Symptoms that accompany the tumor processes,experts divide into renal and extrarenal. In the first case, there are classical manifestations of the disease. Among the typical symptoms should be allocated hematuria (blood in the urine), neoplasm and soreness in the subcostal area, which is felt when palpation (palpation). It should be noted that, according to these signs, an accurate diagnosis can not be made. This is due to the insufficient prevalence of symptoms (detected in about 8% of patients) and not specific to the process of going far. These signs can be noted in other diseases to which the parenchyma of the kidney is susceptible.

It should be noted that in modern medicine, the only option for treating organ cancer is surgical intervention.

Cysts are also referred to as neoplasms. These formations have liquid contents. As a rule, defeat occurs bilateral. In rare cases, a single cyst is identified. This pathology is called polycystic kidney disease. Most often, the disease is hereditary.

Treatment of pathology can be carried out assurgical, and conservative methods. In the second case, the therapy is performed according to the procedure for eliminating pyelonephritis in combination with the use of antibacterial drugs.

In some cases, kidney anomalies are detected. Under this definition, a lot of diseases fall. In particular, the kidney parenchyma can be thinned. Typically, this condition is noted after the infection and treatment is wrong. As a result, the entire renal system undergoes a load. Incorrect treatment, as well as non-observance of certain conditions after therapy, can provoke tissue exhaustion.
