Hi, my dad has chronic kidney disease and has had this for a long time now, he is 60 and has had many scans on his kidneys over the years but the recent one showed he has cysts and enlarged kidneys, could this be poly cystic kidneys or has this developed because of his chronic kidney disease? We have absolutely no history of poly cystic disease in our family so I was thinking the cysts have developed due to his kidneys which have 8% function.
