symptom of kidney stones : Functions of the kidney stone

Kidney Stones

The main functions of the kidneys are to keep the blood pure and healthy and maintain proper fluid balance in the body. To accomplish this difficult feat, the kidneys constantly monitor normal blood volume and filter from the blood the right quantity of urine to keep it balanced. There are many influences that can disrupt this mechanism and cause congestion in the kidneys. They include overstimulation, dehydration, fatigue, overeating, gallstones, blood pressure disturbance, medical or narcotic drugs, vitamins, digestive disorders, etc. When the kidneys are incapable of sufficiently separating the urine from the blood, part of the urine continues to circulate throughout the body, depositing urinary waste products in the blood vessels, joints, tissues, and organs. Skin diseases, strong body odor, sweating of palms and feet, water retention, intestinal swelling, high blood pressure, etc. are all signs of toxic blood caused by crystals and stones in the kidneys.

Stones in the kidneys begin as tiny crystals and can eventually become as large as an egg. The tiny crystals are too small to be detected by X-rays and since they do not cause pain, they are rarely noticed yet they are big enough to block the flow of liquid through the tiny kidney tubules. Crystals or stones are formed in the kidneys when urinary constituents, which normally in solution, are precipitated. Precipitation occurs when these particles occur in excessive amounts or when urine becomes too concentrated. The crystal particles or stones are usually full of sharp angles, which may cut and wear away the inner surface of the urinary canal (ureter) during their passage from the kidneys to the bladder. This causes severe pain in the loins or lower back. There may even be blood in the urine, pain running down the legs, numbness in the thighs and a difficulty in passing urine.

Most crystals or stones originate in the kidneys, although some may also be formed in the bladder. If a large stone enters a ureter, urine flow becomes obstructed. This can lead to serious complications, such as kidney infection or kidney failure.
