Cystic Kidneys

Renal cystic disease is a term that represents a wide spectrum of diseases that may be hereditary, developmental, or acquired; these diseases share the feature of renal cysts. These cysts can occur in the cortex, the corticomedullary junction and/or the medulla depending on the underlying disease process. Acquired cysts can be simple or part of acquired cystic kidney disease (ACKD), also called acquired renal cystic disease (ARCD). ARCD is characterized by the development of numerous fluid-filled cysts in the kidneys in individuals who have no history of hereditary cystic disease. Acquired renal cystic disease is a bilateral condition. It can antedate the clinical recognition of end-stage renal failure. In the early stages, acquired renal cystic disease does not produce symptoms and is usually discovered inadvertently in the course of abdominal imaging procedures.
