A kidney stone may not be as big as the stones in your garden, but can be quite a pain. Kidney stones are actually mineral crystals that are usually a combination of calcium and phosphates. The size of a kidney stone ranges from the size of a sugar crystal to a ping pong ball. While some kidney stones pass out of the body along with urine, others can block the urethra and become painful. 

In addition to being painful, a kidney stone can cause permanent damage to your kidneys. Since large kidney stones are usually painful, they rarely go undiagnosed. However, if a kidney stone is left untreated, it could cause the kidney to atrophy and lower the functionality of the kidney. Kidney stones that are related to an infection can also lead to chronic urinary tract infections and damage the kidney through scarring and inflammation. This could eventually lead to kidney failure.
 
Not all kidney stones need to be treated with surgery. If the kidney stone is very small, your doctor may prescribe plenty of water and medication to treat the pain. With plenty of water, you should be able to pass the stone in your urine. Ideally, you should take plenty of rest until the stone is passed. 

Larger kidney stones may need you to be hospitalized for treatment. These are:
- extracorporeal shock wave lithotripsy (eswl)
To begin this of treatment, a painkiller is administered. Ultrasonic waves are used to determine the location of the kidney stone. Shock waves are then passed through the kidney stone to break it into smaller pieces, which can then pass out of the body through urine.
- ureteroscopy
This is also called retrograde intrarenal surgery and is performed when the kidney stone is stuck in the ureter. A ureteroscope is passed through the urethra and bladder into the ureter. Laser energy may then be used to break the stone into smaller pieces to unblock the ureter. 
- percutaneous nephrolithotomy (pcnl)
This surgery is performed under general anesthesia. It involves a small incision being made in the back and a nephroscope passed into the kidney through it. Laser or pneumatic energy is then used to break up the stone into smaller pieces and pull them out. 

- open surgery
Open surgery is performed only in the case of an abnormally large stone or abnormal anatomy of the person. An incision is made in the back that allows the doctor to access the kidney and manually remove the stone.

Kidney Stones- Should It Be Removed

As we all are aware that waste products in the blood are passed through urine. This filtering process is done by the kidneys as it separates the waste products including minerals and salts, which have to be passed out through urine. Many times, these minerals and salts get stuck in your urinary tract and over a long period, this forms kidney stones. They can vary in size from a ping pong ball to the size of a sugar crystal. They are not noticed till the time they cause a blockage. Sometimes, they cause immense pain if they start breaking or are pushed into the ureters (narrow ducts which lead to the bladder).

Symptoms of kidney stones:
1. Immense pain in the groin, belly and back.
2. Pain while urinating and urination occurring frequently.
3. Blood found in the urine (haematuria).
4. Vomiting and nausea.
5. Feeling extremely restless and not being able to lie still.

Kidney stones can also cause a kidney infection. Signs of kidney infection include:
Kidney stones can also cause infection in the kidneys as they block the passage of urine to the bladder by blocking the ureters. This leads to build up of the waste product which can result in an infection. Some of the symptoms of kidney infections could be:
1. Feeling chilly and shivering on your skin.
2. High temperature of 100.4 F (38C) or more.
3. A feeling of fatigue or weakness.
4. Immense diarrhea
5. Bad smelling and cloudy urine.

Types of Kidney stones:
1. Struvite stones: It contains ammonia and magnesium. It is usually quite large and horn- shaped.
2. Uric acid stones: Brown, smooth and softer than other kinds of kidney stones.
3. Cystine stones: They are yellow and don t look like stones. They usually resemble crystal.
4. Calcium stones: It is composed of calcium.

What causes kidney stones?
Kidney stones can occur due to several factors. It usually forms when urine generally contains crystal substances like uric acid, calcium and oxalate. Your urine might not be able to dilute these substances resulting in the perfect environment for the formation of kidney stones. In case you are showing any of the symptoms mentioned above, you should visit you doctor immediately before the problem can worsen.

Common Symptoms of Kidney Stones

The pair of kidneys that human beings have, forms an important part in the excretory system. They perform specific and important functions. They excrete urine as well as help in eliminating the toxins, which accumulate in the body. Kidney stones occur when the minerals present in the urine without being discharged, keep on accumulating. This gives rise to an extremely painful and uncomfortable situation. Though sometimes the situation gets revoked all by itself, many a times it requires medical intervention. 

Some of the symptoms of kidney stones are: 
1.  Excruciating pain in the back
2.  Pain while urinating
3.  Tendencies to vomit
4.  Dizziness
5.  Fever 

However, there are several preventive measures which you can undertake in order to avert the situation. Some of them are:
1.  Drink lots of water
Kidney stone is one of those rare conditions that once occurred, always carry the latent threat of recurring again. Therefore, drinking water in large quantities becomes essential. The more you drink water, the more frequently you would urinate, thereby curbing the chances of the minerals settling in the kidneys.
2.  Avoid certain foods
Food like beets, spinach, those which are replete with calcium oxalate should be avoided in order to minimize chances of having kidney stones.
3.  Change your diet
If you are trying to avoid the eventuality of developing kidney stones, it is imperative that you change your diet a bit. It is recommended that you exclude animal protein as much as possible and assiduously avoid the intake of salt as much as possible.
4.  Take less calcium supplements
Calcium generally is considered a nemesis to your kidneys and is prescribed by doctors to be avoided. However recent research has thwarted this claim. Calcium does not pose a threat to kidneys. However calcium supplements definitely do and therefore, should be avoided.

All About Kidney Stones

The kidneys may be a pair of small organs but they perform a very important function. Without the kidneys, it is impossible to filter blood and remove toxins from the body. One of the common problems associated with kidneys is the development of a kidney stone. This can be described as a hard, pebble like substance that is formed when urine contains high levels of certain minerals. Kidney stones vary in size and shape. Small stones may pass through the ureter into the bladder and out of the body with minimal discomfort. However, in some cases, a kidney stone can be as large as a golf ball. In such cases, it can block the urine flow and cause extreme amounts of pain as well as bleeding. In such cases, a doctor needs to be consulted as early as possible.

There are four different types of kidney stones.

Calcium Stones: This is the most common type of kidney stones. It is caused by excess calcium that is not flushed out with the urine.
Uric acid stones: Highly acidic urine can trigger the development of such stones. This may be caused by excessive consumption of meat, fish and shell fish.
Struvite stones: This is often formed as a side effect of Urinary tract infections. These stones may develop and grow rapidly.
Cystine stones: These stones are formed as a result of a genetic disorder known as cystinuria. This disorder causes an amino acid known as cysteine to leak into the urine.
Kidney stones are a fairly common occurrence. It affects both men and women but men have a higher risk of developing kidney stones as compared to women. Other risk factors that can influence kidney stones are:

Family history of kidney stones
Not drinking enough water
Obesity
Digestive problems
Recurrent UTIs
Gout
Bowel inflammation
Disease that causes blockage of the urinary tract
Certain medications such as diuretics or calcium based antacids
Once a person has been diagnosed with a kidney stone, this issue can recur. Treatment for kidney stones depends on the type of stones, size and location. In most cases, medication is prescribed to help break the stone down into smaller parts so that it can pass through urine. In extreme cases, surgery may be required. If not treated in time, it can cause severe pain, bloody urine, UTIs that can further lead to kidney failure and reduced kidney functioning.
Kidney stones can be prevented by drinking plenty of fluids and making a few dietary changes. Ideally, a person should have a minimum of 8-10 glasses of water a day. If you have a high risk of developing any type of kidney stones, reduce your sodium consumption and the amount of meat eaten.


Kidney Stones - Are They Really Common?

Treatment for Kidney stones varies depending on the size and type of the stone or the symptoms caused by it. In case of small stones, medication and simple changes in lifestyle can be enough to treat it, but surgeries and extensive treatments are required if symptoms are severe. 

Following are treatment options for kidney stones:

Small stones with minimal symptoms 
1. Drinking water
Drinking around 3 liters of water a day will regulate your urinary system and can effectively eliminate small stones. Unless your doctor advices otherwise, drinking ample amount of fluids, usually water, is one of the commonest way to get rid of small kidney stones. 

2. Pain relievers
There might be a considerable amount of pain and discomfort associated with passing the stone through urine. Your doctor may recommend pain killers like Ibuprofen, Naproxen sodium or acetaminophen. 

3. Medical therapy
In order to eliminate the kidney stone, your doctor may administer medical therapy. Medication like alpha blocker helps in passing the kidney stone with least pain and more quickly. It relaxes the muscles in the ureter and makes the process relatively easy. 

Large stones with severe symptoms
 
1. Using sound waves to break up stones 
In this technique, a procedure called Extracorporeal Shock Wave Lithotripsy (ESWL), is employed. ESWL uses the help of sound waves to create vibrations which breaks the stones in smaller pieces. This procedure takes about an hour and can cause mild pain and discomfort. Your doctor may administer sedatives to reduce your sensitivity. ESWL has side effects like blood in urine or bruising in the abdomen. 

2. Surgical removal of kidney stones 
Surgical removal of stones is done with the help of a procedure called nephrolithotomy. It uses small telescopes and other instruments which are inserted in your back through a small incision. It is generally done in case of large stones and when ESWL fails. 

3. Ureteric Calculi (Using a scope to remove stones) 
A thin illuminated tube called ureteroscope is used to remove a comparatively smaller stone in the kidney or ureter. The ureteroscope is equipped with a tiny camera which determines the location of the stone which is then broken into pieces with the help of other instruments. It may require general or regional anesthesia.

Treatments For Kidney Stones

The kidneys filter the blood and eliminate the waste products through urine. The waste deposition is sometimes in the form of excessive calcium, uric acid and other undesirable contents. It causes the urine to get highly saturated. The solid depositions then turn into stone like formations, also termed as renal lithiasis or calculi. There are different kinds of kidney stones, which are differentiated based on its varied constituents. Kidney stones cause excruciating pain and uneasiness. Frequent urination and discomfort during urination, presence of blood in the urine, are some major signs of kidney stones.

Kidney stones can be prevented by maintaining a healthy lifestyle and a balanced diet with sufficient nutrients:

Calcium and oxalate-rich food should be consumed together. This leads to the binding of calcium and oxalate together in the stomach intestines, before they can be processed in the kidneys. This helps to control the formation of calcium and oxalate depositions in the kidneys.
Do not cut down on calcium. Since most of the kidney stones are found to be calcium depositions, many people tend to cut down on their calcium intake. It is important to continue with food that is rich in calcium such as milk. However, it is necessary to reduce intake of other calcium supplements. Decrease in calcium can lead to degeneration and deformation in bones and muscles.
Too much of red meat consumption and high fat dairy products can lead to the formation of stones in the kidneys. Animal protein is rich in purine that increases uric acid, saturating the urine and creating stones. It is important to balance your diet by including lots of green vegetables, whole grains, fibres, fruits and low-fat dairy products. Opt for non-animal protein such as lentils or legumes.
Cut down on sugary and aerated drinks. They contribute to the formation of depositions due to their high and unhealthy levels of fructose and preservatives.
Reduce or abstain from alcohol. Alcohol is known for its multiple disadvantages to the human body. It has also been found to increase the levels of uric acid in blood.
Keep your body hydrated. Drink adequate quantity of water throughout the day, preferably 3 litres or more depending on your physical activities. It prevents the solidification of the depositions and helps to eliminate wastes smoothly.
Increase the intake of anti-oxidants in the form of green tea, dark chocolates and fruits.
Lower the intake of salt. If you wish to discuss about any specific problem, you can consult a urologist.
