Kidney stones are hard solid mass of minerals and salts that form inside your kidneys.

Kidney stones form when minerals or acid salts in your urine form crystals and can appear in any part of your urinary tract.

Diet, dehydration, excess body weight, some medical conditions, family or personal history and certain supplements and medications are among the many causes of kidney stones.

A kidney stone will not cause symptoms until it moves around within your kidney or passes into your ureters.

If the stones block the flow of urine, the patient will present several symptoms:

-Renal colic (it is an emergency): Renal colic is caused when the stone blocks the normal urine flow through the ureter. It can be accompanied by nausea, vomiting, blood in the urine, painful urination and fever.

-small stones with minimal symptoms can pass in the urine without invasive treatment; the doctor treat the patient by giving a medication like alpha blocker and a pain reliever and by telling him to drink a lot of water.

-large stones with symptoms :when the stone continues to grow and causes severe pain ; an active treatment in necessary ( a surgical treatment): uteroscopy, percutaneous nephrolithomy, parathyroid gland surgery, and shock wave lithostripsy by using sound waves to break up stones.
