JON MARKS, MD: Renal cholic, which is the pain from kidney stones, is among the worst pains anyone will experience. Some people say it's just as bad as childbirth without anesthesia. So pain is a leading sign of kidney stone. There may also be blood in the urine, fever, chills, nausea and vomiting.
PAUL MONIZ: So bottom line, if you have a stone and it's a stone that's causing problems, you'll know it.
JON MARKS, MD: You will know it, and you should be evaluated.
PAUL MONIZ: What about the evaluation? What can be done about these stones?
JON MARKS, MD: Well, we need to find out where the stone is, so the first thing that is done is some form of an X-ray or an ultrasound or a CAT scan. Some radiographic imaging procedure that shows us inside the body where the stone is and how large it is.
PAUL MONIZ: And Dr. Salant, finally with you, the role of diet. If people have stones or they are susceptible to them, how should they change their diet?
ROBERT SALANT, MD: Depending upon the composition of the stone, that will determine what types of foods you should either avoid or use as a supplement. However, the key modality in preventing new stones from forming is to be very well hydrated. Drink approximately three liters of fluid per day.
PAUL MONIZ: Very good advice. Dr. Robert Salant, thanks for your time and Dr. Jon Marks as well. Remember, kidney stones are extremely common, effecting 1 in 10 Americans every year. I'm Paul Moniz. Thanks for being with us.
