Kidney Stones

A kidney stone is a solid piece of material that forms in the kidney from substances in the urine. It may be as small as a grain of sand or as large as a pearl. Most kidney stones pass out of the body without help from a doctor. But sometimes a stone will not go away. It may get stuck in the urinary tract, block the flow of urine and cause great pain.

The following may be signs of kidney stones that need a doctor's help:

* Extreme pain in your back or side that will not go away
* Blood in your urine
* Fever and chills
* Vomiting
* Urine that smells bad or looks cloudy
* A burning feeling when you urinate

Kidney Diseases

Your kidneys are two bean-shaped organs, each about the size of your fists. They are located near the middle of your back, just below the rib cage. Inside each kidney about a million tiny structures called nephrons filter blood. They remove waste products and extra water, which become urine. The urine flows through tubes called ureters to your bladder, which stores the urine until you go to the bathroom.

Damage to the nephrons results in kidney disease. This damage may leave kidneys unable to remove wastes. Usually the damage occurs slowly over years. There are no obvious symptoms, so you don't know it is happening.

Many things can cause kidney disease. You are at risk if you have

* Diabetes
* High blood pressure
* A close family member with kidney disease

Your doctor can run tests to find out if you have kidney disease. If your kidneys fail completely, a kidney transplant or dialysis can replace the work your kidneys normally do.
