What causes the occurrence of renal cysts? This is the patients and experts need to understand the problem, understand the cause of the disease can be more targeted treatment, the cure of the disease is very helpful. What causes the occurrence of renal cysts?
What is the kidney cysts - one of the causes of speculation
The cause of renal cysts by congenital hereditary or acquired dystrophy, kidney damage, collaterals and renal cysts caused by bloody cystic disease. Renal cysts are benign tumors, simple renal cysts are the most common, including the right kidney cyst and left renal cyst. The incidence rate is over 50% in people over 50 years of age. Generally single-sided single, there are multiple or multi-polar, bilateral rare. Unilateral and inpidual renal cysts are relatively harmless and are often overlooked clinically. Any age can occur, but more than 2/3 of the patients found in the crowd over the age of 60, is considered an elderly disease. What is the cause of renal cysts, cysts from the renal parenchyma, highlight the surface of the renal cortex, the appearance of blue, but can also be located in the renal cortex deep or medulla. Thin wall, a single layer of flat epithelium, capsule containing clear serous liquid. Capsule wall thickness and not smooth, liquid bloody, suggesting that there may be malignant, malignant rate of 3% to 7%. Located in the lower pole of the huge kidney cysts, can oppress the ureter caused by obstruction, effusion and infection.
What is the kidney cyst - the causal speculation of the two
The cause of renal cysts is not clear, may be caused by renal parenchymal ischemia. The cause of renal cysts Recently, a professional that is due to the existence of the transition from the renal tubular perticulum. Renal cysts can be single or multiple, often involving unilateral kidney, even with contralateral kidney disease. Capsule liquid in the chemical composition and plasma ultrafiltration similar to the appearance of urine, even bloody. Measured, intracapsular fluid may have nearly 20 cycles of secretion per day. Capsule diameter is generally 0.5 ~ 1cm, also up to 3 ~ 4cm or even larger. Typical wall of the wall is very thin, transparent, after multiple infections can also be thickened, fibrosis and even calcification. Light microscopy, the capsule wall covered by a single layer of flat epithelial cells can be non-continuous arrangement. Electron microscopy, epithelial cell morphology and ultrastructure similar to proximal or distal renal tubular epithelial cells, depending on the origin site. With the increase in cysts, the oppression can damage the renal parenchyma, but still not to damage renal function. An isolated cyst site can be just oppression to the ureter, causing progressive hydronephrosis, this situation can be followed by infection.
What is the kidney cyst?
Renal cyst disease and kidney essence deficiency, poor blood, phlegm endogenous, vein silt resistance related. What causes the occurrence of renal cysts? The above is a specific description of the problem, and hope to help everyone, usually pay more attention to these reasons, do preventive work to reduce the risk of disease.
