Polycystic
Polycystic kidney is a cystic disease of the kidney. There are two types of autosomal dominant polycystic and autosomal recessive polycystic, and the former is much more common than the latter. It occurs in some animals including humans. The kidneys are covered with cystic blisters, and only one kidney develops in only 17%. Most of them develop into both kidneys in adults. The number of blisters is enormous and filled with liquid. Blisters increase the volume of the kidneys, but normal cells are reduced to cause kidney failure. In addition to kidneys, blisters can also form in the liver and pancreas, and are very rare, but can also occur in the heart and brain. Polycystic newborns are among the most common of life-threatening hereditary diseases. It is estimated that there are 12.5 million patients worldwide.
