Kidney stones are created when certain substances in urine -- including calcium, oxalate, and sometimes uric acid -- crystallize. These minerals and salts form crystals, which can then join together and form a kidney stone.
Kidney stones usually form within the kidney, where urine collects before flowing into the ureter, the tube that leads to the bladder. Small kidney stones are able to pass out of the body in the urine -- and may go completely unnoticed by you. But larger stones can irritate...
Waves of sharp pain in your back and side or lower abdomen. The pain may move toward the groin or testicles.

Nausea and vomiting with ongoing flank pain
Blood in the urine

Sometimes an infection is also present, and may cause these additional symptoms:

How Are Kidney Stones Diagnosed?
Because the symptoms of kidney stones can also be signs of other urinary problems, your health care provider will confirm that you have a kidney stone with blood and urine tests. Imaging studies may also be used to examine your kidneys and urinary system including:
Intravenous pyelogram (IVP)
X-ray called a "KUB" for kidney-ureter-bladder X-Ray
