You should always be concerned about your health. And you should do all you can to prevent kidney disease and kidney failure.
Avoid too much soda, drink plenty of water, never hold in your urine for too long. When you feel the urge to urinate make sure you try and get to a restroom as soon as possible.
You should have regular blood tests done as well to look for signs of kidney disease. If your kidney disease is found early it's much easier to get it treated.
