Changes of the renal parenchyma

Diffuse changes of renal parenchyma

The kidney is covered with connective capsule, which consists of specific tissues, the system for the allocation and accumulation of urine. Specific tissue is group of cells consisting of brain and cortical substance. The renal parenchyma is formed by the group of cells and has the ability to recover. To determine the state of the parenchyma of the kidneys used of the study of CT and ultrasound.

Diffuse changes of renal parenchyma occur for several reasons. This can be the initial phase in the progression of stone disease, education pyramids of plaques that turn into kidney stones. Hyperechogenic inclusions can represent these changes, and in some cases this is due to the renal vessels or fat tissue. Only a comprehensive study of the authority can identify the disease.

The renal parenchyma may be affected by numerous benign and malignant entities. Among the common benign tumors are adenoma, oncocytoma, angiomyolipoma. To malignant formations include kidney cancer. Symptoms that accompany neoplastic processes shared by renal and extrarenal, but they appear almost the same. Among the typical symptoms distinguish the presence of blood in the urine, pain in the hypochondrium, perceptible to the feeling.

It should be noted that may experience these same symptoms in other diseases affecting the renal parenchyma. The disease occurs acutely and is chronic. Diffuse loss of parenchyma is observed in the chronic form of pielonefrita.

Detection of the asymmetry in size shadows of the kidney, deformation of the Cup-pelvis-plating system, uneven contours, irregular reducing the thickness of the renal parenchyma indicates chronic pyelonephritis, and means that a pathological process has gone too far. In anamnesis – acute pyelitis, cystitis, acute urinary tract infection.

Cyst of the renal parenchyma

When the fluid retention in the nephron occurs solitarily or simple renal cyst. A simple renal cyst presented a single thin-walled formation that develops from the renal parenchyma. Is oval or round in shape, contains serous or hemorrhagic fluid. The size of the simple cysts are no more than 8-10 cm, a huge cyst can contain up to 10 liters of fluid. Timelyremoving the cyst or draining it promotes faster recovery and salvation of kidney possible due to the high plastic properties in its parenchyma.

Multilocularis in the diagnosis of renal cyst, you can see that its parenchyma is susceptible to cystic and dysplastic changes. It has a multi-chamber cyst, expressed clear boundaries, this can lead to cystic forms of cancer. Diagnostic measures begin with radiographic screening (ultrasound) methods. Performs computed tomography and percutaneous puncture cystography. Surgical interventions are performed mainly in patients of young and middle-aged.

Of the several methods of getting rid of cysts are practicing the technique of puncture of renal cyst under ultrasound control. This method of treatment consists in puncturing the cyst with a needle, removal of the contents and the introduction in its cavity with a special substance which bonds the wall of the cyst. Also used laparoscopic excision of the walls of the cyst, i.e., the removal of cystic masses in any area of the body.

Symptoms of simple kidney cysts is the dull pain in the hypochondrium or the rump, probing the tumor in the lumbar region, increased blood pressure and total haematuria (blood in urine). In congenital polycystic kidney disease, preferably a therapeutic symptomatic treatment, to prevent further growth of the cysts, contributing to the preservation of the kidney function as long as possible. The most radical way of getting rid of rodents is to defer kidney transplantation.

Thinning of the renal parenchyma

Thinning of the renal parenchyma can be caused by various anomalies, including the transferred infections or incorrectly chosen methods of treatment. So all diseases relating to the urinary system should be treated promptly, carefully, and preferably to constantly carry out preventive measures. The thickness of the renal parenchyma in young people is 1.5-2.5 cm With age, it also becomes thinner in people older than 60 years of its thickness does not exceed 1.1 cm

The thinning of the renal parenchyma is reduced and the size of the kidneys. The thickness of the renal parenchyma is reduced in chronic renal diseases characterized by scarring of the organ.
