A kidney stone is like a small rock that forms in the kidney. Stones form when certain chemicals in the body clump together. A stone can either stay in the kidney or travel through the urinary system by passing though the urine and not causing any harm.

What are the symptoms?

Very small stones might pass through the urinary system without causing much pain. Larger stones can block the flow of urine if they get stuck in the ureters or urethra. Kidney stones do not usually cause any symptoms until they start to pass. Some symptoms might include:

Extreme pain in your back or side that will not go away

Nausea

Blood in your urine

Fever and chills

Who are at risk ?

Anyone can have a kidney stone, but it may be more likely if you:

Are male and are overweight

Have had kidney infections

Have a family member with kidney stones

Have had kidney stones before

Eat a lot of animal protein (such as meat and eggs)

Do not drink enough liquids

Have certain medicines which can cause kidney stones

How are kidney stones treated?

Treatment depends on the location and size of the kidney stone. Drinking plenty of water and taking some medicines can help a small stone to pass more easily. For problem stones, there may be a few options:

Lithotripsy uses shock waves to break a large stone into smaller pieces that can pass.

Ureteroscopic Stone Removal uses a small tool to get and remove stones stuck in the ureters.

Percutaneous Nephrolithotomy uses surgery to remove large stones from the kidneys.

Depending on the location of the kidney stone and many other factors the doctor decides on the most suitable procedure.

How can I prevent kidney stones?

If you have had kidney stones before, you are more likely to have kidney stones again. To help keep stones from forming, try to:

Drink 10 to 12 glasses of water each day

Eat less salt (sodium), meat and eggs

Find out what type of stone you have

Ask your doctor for a urine test

Talk to your doctor about your medicines and other tests for kidney stones

Do NOT reduce the calcium in your diet without talking to your doctor first! Studies show that limiting calcium in your diet may not stop kidney stones from forming and may harm your bones.

Kidney Stones - Are They Troubling You?

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

What are kidney stones?
The primary function of the kidney is to 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 may cause the urine to get highly saturated. This is when stone like formations take place inside the kidneys. Kidney stones are also termed 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, extreme discomfort during urinating and presence of blood in the urine are some of the major signs of kidney stones. The symptoms are not evident if the stones are very small in size.

Causes of kidney stones:

Incorrect calcium intake: High amounts of calcium can lead to high calcium depositions in the kidneys. It is important to keep the calcium intake moderate. Calcium supplements must be checked if you have already included dairy products in your diet.
Abnormal rates of sodium in the body: Sodium, just like calcium, gets deposited in the kidneys.
Excessive animal protein intake: Too much of animal protein intake can make the urine turn acidic, leading to uric acid depositions in the kidneys.
Sugary, aerated drinks: These lead to undesirable waste deposition in the blood stream and eventually in the kidneys.
Inadequate water intake: Not keeping the body well hydrated can cause the urine to turn acidic and increase waste deposition.
Potential risks and complications of kidney stones:

Kidney stones may cause an infection in the kidneys which may eventually spread to the other internal organs and surrounding tissues.
Kidney stones block the ureter and cause severe pain and discomfort that make sitting, standing or any other posture difficult.
Kidney stones rarely cause kidney failures but the severe blockage and infection may cause such detrimental results in the human body.

Kidney Stones - 5 Causes Behind It!

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

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

Kidney stones are caused when certain minerals of your urine are retained and are not fully released, causing them to amalgamate and form a stone. Passing a kidney stone is one of the most painful experiences you may face physically. Its magnanimity is often compared to childbirth, and those who are suffering from kidney stones dread having this experience. If you are not yet affected by kidney stones and do not want to, read further to know what type of diet you need to follow in order to prevent it.

1. Drink lots of water: On an average, a person must be drinking at least 3 liters of water every day. If you live in a more hot and humid climate, your water intake must be even more than that, so that on an average, 2.5 liters of urine is passed throughout the day, which decreases the chance of unnecessary retention of minerals from the urine and release them more easily from the body.

2. Continue eating foods rich in calcium: It is a common misconception that calcium accelerates the formation of kidney stones. Calcium is digested by the intestine, only excess calcium cannot be digested by the intestine and is sent to the kidney. Continue consuming calcium rich foods unless your doctor prescribes you against it. Make sure your diet includes enough dairy products such as milk, cheeses, etc., or other calcium rich foods, such as oats and broccoli.

3. Limit intake of oxalic acid: Oxalic acid is mostly found in foods obtained from plants. It restricts the absorption of calcium in the intestines and as a result, more calcium is passed into the kidneys; thus, forming calcium oxalate, or oxalate stones. Try to avoid foods, such as rhubarb, Swiss chard, nuts, tea, sweet potatoes, etc.;mainly leguminous plant products.

4. Decrease the ingestion of sodium salts, sugar and meat protein: Salts and sugars, mainly found in packaged foods are used to prevent them from expiring. They increase the release of calcium and oxalates into the blood, which thus increases the chance to develop kidney stones. Meat contains fibers which affect certain nutrients in the kidney, thus aggravating the formation of stones.

5. Increase the consumption of insoluble fibers: Insoluble fibers are those rough fibers which are not soluble in water during the process of digestion. They are found in rice, wheat, barley, etc., and are found to decrease calcium absorption in the kidney. They attach themselves to the calcium and oxalates, which enable them to be released as stool instead of urine.
