Let’s prevent kidney stones

Urinary stones are a very common condition. This is a solid substance formed by the chemical substances in the urine.

This condition is most common in people between the ages of 30-50. Urinary stones increase the risk of developing Chronic Kidney Disease (CKD) in the future. Once urinary stones occur, the risk of recurrence within 50-7 years is 50% higher.

Why do urinary stones occur?

Various impurities in the urine dissolve and are excreted from the body. There must be enough water to dissolve the waste. Or the waste may be deposited around the urinary system in the form of granules. These combine with other materials to form larger solids. They are transported and deposited in the urinary tract. There are a number of factors that contribute to this.

1. Urinary stones in a previous case

2. Family history of urinary stones

3. Not drinking enough water

4. Excessive consumption of animal protein

5. Excessive consumption of foods high in sodium / salt and sugar

6. Overweight or obesity

7. Presence of gastrointestinal diseases

8. Certain types of drugs

Types of urinary stones

1. Calcium Oxalate Stones

This is how it is most commonly seen. Reducing the amount of oxalate in the diet can reduce the risk of these types of stones.

2. Uric acid stones

This pattern is most common on the male side. As the acidity of the urine increases, the risk of developing stones of this type increases. To do this, you need to control the amount of animal protein in your diet.

3. Struvite / magnesium ammonium phosphate stones

This method is common among women. Urinary tract infections can cause this. Slightly larger stones can cause an eruption of the urinary tract. This way you can reduce the risk of developing stones and prevent urinary tract infections.

4. Cystine ( cysteine ) stone

This method is somewhat rare. It affects both men and women equally. Often caused by a genetic influence.


Although urinary stones occur in the kidneys, they travel along the urinary tract and deposit in the associated areas, causing symptoms. Sometimes small stones can easily pass through the urinary tract, causing asymptomatic symptoms.

1. Acute pain in the back or lower back

2. Bleeding with urine

3. Vomiting and nausea

4. Feeling cold with fever

5. Abnormal odor emanating from the urine

6. Abnormal appearance of urine

7. A small amount of urine

8. Pain or inflammation when urinating


1. Blood tests

2. Urine tests

3. Scans (CT scan, X ray, IVP test)

4. Ultrasound scanning

How to prevent urinary stones?

Risks can be avoided by making good lifestyle changes. If you have a risk factor similar to the one described above or have been treated once, under the proper guidance of a dietitian or nutritionist, this condition can be prevented from recurring. If you have any of the above symptoms, you should seek medical advice and treatment. Then the lifestyle should be maintained so that those conditions do not happen again.

1. Drink enough water.

If the urine is dark yellow, it is evidence that you are not drinking enough water. It is best to keep the color of the urine light yellow or colorless. Need to drink more than 2 liters of water a day. You should drink more water if you exercise or live in a hot environment.

2. Eat more vegetables and fruits.

3. Eat a diet high in salt and sugar.

4. If you are overweight or obese you should reduce the weight to the prescribed value.

Diet plans for weight loss are often high in protein. Often these are supplemented by animal proteins. (Meat, fish, liver or organ meat). These increase the acidity of the body and stimulate the formation of urinary stones. If you are at risk for urinary stones, do not overeat animal meat. Therefore, weight loss should be done under the supervision of a qualified nutritionist/dietitian.

5. Get more oxalate with diet

Tea, peanuts, spinach, beetroot, sweet potatoes, chocolate, peppers, soy products, and okra are all high in oxalate.

5. Eat foods rich in calcium, including dairy products.

But be careful when taking calcium supplements. It should be done on the advice of a qualified person.

In this way it is possible to lead a healthy life by being aware of the disease and maintaining the right lifestyle.
