What is kidney cyst

summary

Kidney has "congenital essence", which is the foundation of yin and Yang of viscera and the source of life. Therefore, kidney is called "congenital essence". From this point of view, kidney is very important to us, so we must not ignore kidney disease. Let's talk about what kidney cyst is.

What is kidney cyst

First of all, cysts are benign tumors, which are classified as renal cystic diseases. In renal cystic diseases, simple renal cyst is the most common. The incidence rate of people over 50 is over 50%. It is usually unilateral single, but also multiple or multipolar, bilateral rare. Unilateral and single renal cysts are relatively harmless and often neglected clinically.

Secondly, unilateral and single renal cysts are relatively harmless and often neglected clinically. It can occur at any age, but more than 2 / 3 of them are seen in people over 60 years old, which is considered as senile disease. The cyst wall is thin, and it is a single layer of flat epithelium. The cyst contains clear serous fluid, which is produced from the renal parenchyma and protrudes from the surface of renal cortex. The appearance is blue, but it can also be located in the deep layer of renal cortex or medulla.

Finally: if the cyst contains clear serous fluid, the wall of the cyst is thick but not smooth, and the fluid is bloody, it indicates that there is possibility of malignant transformation, and the malignant transformation rate is 3% - 7%. Large renal cysts located in the lower pole can compress the ureter, causing obstruction, effusion and infection. The cause of the disease is not completely clear, which may be related to congenital glomerular and tubular structural abnormalities and acquired injury and infection.
