Cysts can be filled with air or fluid. Cysts that form on the kidneys usually contain fluid. One or more cysts may develop on small tubes in the kidneys. The simple kidney cyst is different from the cysts that develop when a person has polycystic kidney disease, which is a genetic disease. Although its cause is not fully understood, the simple cyst is not an inherited condition. Simple kidney cysts become more common as people age. Nearly 30 percent of people over the age of 70 have at least one simple kidney cyst. less

There are two types of PKD: Autosomal Dominant Polycystic Kidney Disease (ADPKD) and the less-common Autosomal Recessive Polycystic Kidney Disease (ARPKD).It occurs in humans and some other animals. PKD is characterized by the presence of multiple cysts (hence, "polycystic") in typically in both kidneys; however 17% of cases initially present with observable disease in one kidney, with most cases progressing to bilateral disease in adulthood. The cysts are numerous and are fluid-filled, resulting in massive enlargement of the kidneys. The disease can also damage the liver, pancreas and, in some rare cases, the heart and brain. The two major forms of polycystic kidney disease are distinguished by their patterns of inheritance. less

Kidneys affected by nephrotic syndrome have small pores in the podocytes, large enough to permit proteinuria (and subsequently hypoalbuminemia, because some of the protein albumin has gone from the blood to the urine) but not large enough to allow cells through (hence no hematuria). By contrast, in nephritic syndrome, RBCs pass through the pores, causing hematuria.According to NephCure, most often, Nephrotic Syndrome is defined by its primary diseases that attack the kidney’s filtering system. Some of these cases are idiopathic. less

Transitional cell carcinoma, which affects the ureters, can also begin in the kidneys. Children are more likely to develop a kind of kidney cancer called Wilms' tumor. The incidence of kidney cancer seems to be increasing, though it isn't clear why. Many kidney cancers are detected during procedures for other diseases or conditions. less
