Adult renal cyst is a congenital genetic diseases, renal parenchyma filled with countless size, ranging from round cysts are not connected with the outside world, the capsule containing a liquid, small invisible, large several centimeters , it is called polycystic kidney disease. Nocturia increased performance, low back pain, high blood pressure. Urine, hematuria, and a small amount of proteinuria, often slowly develop into chronic renal failure. 10% of people with kidney stones, 30 percent of the people associated with polycystic liver disease. Experienced doctors with the B ultrasound, intravenous pyelography can be diagnosed.
Simple renal cysts may be a congenital anomaly, unilateral or bilateral renal and one or several sizes of round is not connected with the outside world cysts, mostly unilateral, it is called simple renal cysts. Its incidence can be readily age increased over the age of 50 do B, 50% can be found in the cyst. With B ultrasound, CT can be diagnosed.
Unique characteristics of simple renal cysts:
Simple renal cysts is clinically most common form of cystic kidney disease, Polycystic different, the disease is not congenital but acquired in the past that it is caused by ischemia, studies suggest that in recent years may be caused by tubular diverticula evolved. Age, the distal tubules and collecting and diverticula increase the incidence of simple renal cysts is also increased. Mainly seen in adults, the incidence increases with age, more than 50 years of age about half of the at least one cyst.
The cyst can be single or multiple and it can be in one kidney or both the two kidneys. Cyst is generally isolated spherical, may change the kidney in the renal cortex superficial appearance, but also can be located in the cortex deep or medulla, 0.5 to 1 cm in diameter, can also be 3 to 8 cm, the wall is thin, transparent, yellow liquid containing grass more viscous and, if too inflammation, the wall may be thickened, fibrosis and even calcification. Cysts and renal pelvis is not the same wall lined with simple squamous epithelial cells.
The disease is generally not the onset of symptoms, often due to other purposes or examination inadvertently discovered. Even there may be hematuria and pain, calyceal obstruction and secondary infection. The emergence of an individual due to compression of adjacent vessels and cysts, resulting in ischemia and renin increased blood pressure, suction capsule solution or removal of cysts, blood pressure will be reduced to normal, and occasionally can cause polycythemia. The disease does not lead to renal dysfunction. Slow the natural variability of simple renal cysts.
Acquired renal cysts are mainly due to uremia or dialysis. Age has nothing to do with the time of hemodialysis. The kidneys had no renal cysts, reported in the literature, duration of dialysis over three years; most patients will appear to the cyst. One of its renal least four cysts, diameter of 2 to 3 cm, and some cysts can be infection, and even cancer, B ultrasound or CT can be diagnosed.
