Causes of renal cyst

summary

My brother was born with kidney disease. When he was young, he was diagnosed with cyst. My family attached great importance to it. However, our family did not have this genetic history, and my parents did not have this genetic disease. So we are very curious about the causes of renal cysts, let's briefly introduce the causes of renal cysts.

Causes of renal cyst

First, the wall of renal cyst is thin, and it is a single layer of flat epithelium. The cyst contains clear serous fluid. If the cyst wall is thick but not lubricated, and the fluid is bloody, it indicates the possibility of malignant transformation. The malignant transformation rate is 3% - 7%. Large renal cysts located in the lower pole can crush the ureter and cause obstruction, effusion and infection. The cause of the disease is still unclear, which may be related to congenital glomerular and tubular structural abnormalities and acquired injury and infection.

Second: renal cysts are visceral cystic diseases caused by congenital inheritance or acquired dystrophy, kidney qi damage, and disharmony of collaterals. Renal cysts are benign tumors, which have been classified as renal cystic diseases. In renal cystic diseases, simple renal cyst is the most common. In the population over 50 years old, the incidence rate is more than 50%. It is usually unilateral and single, but also multiple or multipolar, rarely bilateral. Unilateral and single renal cysts are relatively harmless and often ignored 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. Cysts are produced from the nature of the kidney, protruding from the surface of the renal cortex. The appearance is blue, but they can also be located in the deep layer of the renal cortex or medulla.

Third: renal cyst is not easy to be found, most asymptomatic, common diameter of 10 cm only cause symptoms, mainly for the side of the abdomen or back pain, when complications appear, the symptoms are obvious, if a large amount of bleeding in the capsule makes the capsule wall suddenly stretch, capsule compression can occur lumbar colic, secondary infection, in addition to the pain aggravation, can be accompanied by increased body temperature and systemic discomfort, ordinary No Hematuria, occasional cyst squeeze adjacent renal essence can produce microscopic hematuria, sometimes cause hypertension. When the cyst is large, mass may appear in the waist and abdomen.
