Renal cyst is one of the causes of the disease. The etiology of renal cyst is unknown. It may be due to renal parenchymal ischemia. About the cause of renal cyst, recently, some professionals believe that it is from the existing perticulum of renal tubules. Renal cysts can be single or multiple, often involving unilateral kidney, and may even be associated with contralateral renal disease. The fluid in the cyst is similar to the plasma filtrate in the chemical composition, the appearance is like urine, and sometimes it is bloody. It is determined that the fluid in the capsule has nearly 20 secretory cycles per day. The inner diameter of the capsule is generally 0.5 ~ 1cm, and can reach 3 ~ 4cm or even greater. The typical cyst wall is thin and transparent. It can thicken, fibrosis and even calcification after multiple infections. Under light microscopy, a single layer of flattened epithelial cells in the cyst wall is covered with discontinuous arrangement. Under electron microscopy, the morphology and ultrastructure of epithelial cells are similar to those of proximal or distal renal tubular epithelial cells, depending on the site of origin. With the enlargement of the cyst, the compression can damage the parenchyma of the kidney, but it does not damage the renal function. The site of an isolated cyst can just press into the ureter and cause progressive hydronephrosis, which can then be complicated by infection.
How is the renal cyst: etiology of renal cyst of the two cause of speculation from inherited or acquired dystrophy, kidney damage and cystic disease caused by renal collaterals with blood cohesion. Renal cyst is a benign tumor, and simple renal cyst is the most common, including right renal cyst and left renal cyst. In people over the age of 50, the incidence is over 50%.

Any age may occur, but more than 2/3 of patients are found in people over the age of 60, considered to be senile diseases. How can renal cysts arise? Cysts arise from the renal parenchyma, prominent on the surface of the renal cortex, and appear blue, but can also be located in the deep or medulla of the renal cortex. The cyst wall is thin, single layer squamous epithelium with clear serous fluid. The cystic wall is thick and not smooth, and the liquid is bloody. It suggests the possibility of malignant change, and the canceration rate is from 3% to 7%. A huge renal cyst at the lower pole that can cause obstruction, fluid accumulation, and infection in the ureter.
