Alternatively if the urine is very concentrated a stone is more likely to be produced. This is why kidney stones are more likely to occur in hot weather or in people who do not drink much fluid. There are certain conditions which result in the kidney producing cysts filled with urine, such as polycystic disease of the kidneys. The urine inside the cysts tends to lie stagnant and therefore is liable to allow stones to form within it.
