The kidneys are a pair of two bean shaped organs. They reside in the upper abdominal cavity. The right kidney is little lower than left to accommodate the liver.

Some of the key functions of the kidneys include:

Excretion of waste: The kidneys filter out impurities, toxins, excess salts and urea. Urea is produced in the liver and transported via blood to the kidneys for removal.
Balancing water level: As the kidneys are mainly concentrated in the production of urine, they balance the body's water level throughout the day. If the water intake decreases, the kidneys leave water in the body instead of excreting it out and vice versa.

Blood pressure regulation: The kidneys require constant pressure in order to filter the blood. The kidneys increase the pressure if it drops too low and the vice versa.
Acid regulation: Food we eat either increases the acid in our body or decreases it. In order to achieve body's proper functioning, there is a need to balance the pH factor of our body which is done by the kidneys.

Because of such a long list of the functions that our kidneys perform, they are susceptible to encounter problems such as stone in kidney. Nephrolithiasis is a scientific name given to kidney stone formation. Kidney stones are comprised of a compound called calcium oxalate formed as a result of strong bonding of dissolved minerals in a precipitated manner inside the kidneys. The stone formed can be small as a sand particle that remains undetected and passed out via urethra or can be large as golf ball that needs urgent medical attention.

Kidney Stone Symptoms: The most common symptoms include pain at the abdomen or groin in the episodes of lasting from 20 to 60 minutes of varying intensity like pain waves or fluctuations, Fever and chills (indication of infection in the urinary tract), blood along with urine, cloudy or foul smelled urine, pain while urinating, nausea and vomiting, extreme urge to urinate.

There are a number of ways to treat the kidney stones that depends upon the severity of the problem. Small manageable stones need proper medication to relieve from pain and weaken the bond of stones. There are both allopathic and herbal treatments available to perform such tasks. For those people whose stones are that much big that comes under the emergency section are usually recommended for surgical methods for its removal.

Surgery versus herbal treatment for kidney stones: Though there are numerous available treatments for stones in kidney, there is always a debate for these two cures: surgery verses herbal treatment to cure kidney stones. Surgery no doubt removes the stone at that instant but its later causes are even more dangerous. The probability of recurrence of kidney stones is very common. In order to remove it permanently, the herbal treatment to cure kidney stones permanently is always more than effective.
