Getting a lower blood pressure through the use of laxatives will reduce the work load on the kidneys and controlling the blood sugar, and alkalizing will allow the kidneys some recovery. It depends on what kind of kidney disease it is but generally speaking, a majority will have an acidic urine, which is what is killing the kidney. An acid is digesting the kidneys leading to the problem. I would prefer to use just baking soda, such as 1/4 teaspoon of baking soda in 1/2 glass of water twice a day.
As mentioned before, the use of a lemon and baking soda (2 tablespoon of lemon or lime juice plus 1/2 teaspoon of baking soda taken twice a day) will reduce the calcium buildup and hence will reduce the cysts. Certainly it will prevent newer ones from forming, but once formed, it can take a lot of time, such as 3-6 months for example with the alkalizing, but this very much depends on the size.
