Kidneys are important part of the body’s cleansing system. They filter blood, maintain fluid balance and eliminate waste products.

Sometimes minerals in the urine can create conglomerates, forming so-called kidney stones.

Kidney stones, medically called nephrolithiasis, are commonly made up of calcium oxalate. This substance can be found in some foods (nuts, chocolate, certain fruits and vegetables) and supplements.

Occasionally kidney stones may contain uric acid, cystine or struvite.

There is no single underlying reason for nephrolithiasis. Being dehydrated, staying on protein-rich, high-sodium diet can trigger kidney stones in those, who have family predisposition for this problem.

It was also found that consumption of some medications (topiramate, indinavir, diuretics) can play a great role in the creation of the stones.

Actually they stay asymptomatic, till these conglomerates don't travel into the ureter (a tube, which normally deliver urine to the bladder).

If the stone is big enough, it can block ureter and hinder urine outflow. That causes combination of these symptoms:

#1. Pain – this word can't fully describe all sensations, felt by a person with renal colic. It is often compared with childbirth-feelings.

#2. Uncomfortable urination – painful urination is commonly related to urinary tract infection. But it may also become apparent, when a stone runs through your ureter into the bladder.

#3. Hematuria – it is a medical term for bloody urine. Sometimes people with kidney stones notice that their urine has become red, brown or pink. In other cases blood in the urine can stay invisible for the naked eye and may be detected only during urine test.
