When this congenital anomalies in the parenchyma of the kidneys, mainly in the cortical layer, formed a single cyst value from grape to the head of the newborn. Cyst wall consists of fibrous membrane lined inside cubic epithelium.
Cyst filled colorless clear liquid containing proteins and elements of urine, sometimes fat, cholesterol or blood detritus. In the latter case, the liquid becomes reddish or brown color. There is a cyst, mainly in the lower, less often in the top half or the lateral edge of the buds (Fig. 59).
Solitary cysts small size usually does not cause disorders. Large cysts are accompanied by a dull pain; putting pressure on neighboring organs, they cause a delay of stool and gas, nausea, shortness of breath.
