Let’s delve deep into the issue. It will help you take the necessary steps to face it and overcome the problem.

What Are Kidney Stones?

The urine is the fluid that clears the toxic buildup from the body. So, the urine is a complex fluid. It looks like just water. But, it has several chemicals and minerals in it. The minerals in the urine have a high chance of becoming supersaturated. Hence, it results in the crystal formation that becomes gravel after binding with protein. Therefore, the excess protein in urine results in the stone formation. The kidney stones are also known as renal calculi as the principal element in the stone is calcium (80% of the time). In some cases, the stone has the following composition:

  • Struvite (5%-15%)
  • Uric Acid (5%-10%)
  • Cystine

It can occur anywhere in the urinary tract. So, the stones may appear mostly in the parts:

  • Kidneys
  • Bladder
  • Urethra
  • Ureters

Types Of Kidney Stones


You may think that all the kidney stones have the same crystal composition. But, no. You can differentiate the stones based on its composition.


It is the most common components that can affect more than 80% of the population. It may contain the following:

  • Calcium Oxalate
  • Calcium Phosphate
  • Calcium Maleate

You can develop the stones with calcium composition by eating calcium oxalate-rich foods. With your body (liver) producing the oxalate, it can lead to stone formation. So, you need to consume the following food in moderation:

  • Peanuts
  • Chocolate
  • Potato Chips
  • Beets
  • Spinach

The stones can also have the calcium phosphate composition. It is common in some of the metabolic conditions, headaches, or medications.

Uric Acid

The stone with uric acid composition is found more in men compared to the women. In such cases, the stone develops as a result of the high acidic composition of the urine. It happens due to the following:



It occurs in people who lose too much fluid or drink very little fluid. So, people who do not drink sufficient water are at risk.


People with gout or undergoing chemotherapy for cancer have high levels of acidic urine. It can result in stones.

High-Protein Diet


Another major reason is the inclusion of a high-protein diet. Consuming food that has purines can raise the acidic levels of urine. So, eating animal protein (containing purine), meats or shellfish can result in stone formation.


It is the stone composition formed as a result of infections in the body. It is common among women. The main cause of struvite is the urinary tract infection resulting in large stone resulting in urine obstruction. To prevent the stone formation, it is important to seek treatment for the underlying infection.


The cysteine is a rare occurrence that affects men and women. It happens due to the genetic disorder cystinuria. So, the body produces acid naturally in the body. It leaks from the kidneys into your urine stream causing the stone. But, the stones are rare in nature.

Who Are At Risk Of Kidney Stones?

A kidney stone forms in the body as a result of the lack of liquid in the urine. So, it fails to dilute the chemical waste like oxalate, calcium, and phosphorous. It can lead to the crystal formation as the urine becomes concentrated. As the condition is common, you may wonder about the risk factors. Any person who produces less than one-liter urine a day can get the problem. It can affect the following people:

  • People in the age group of 20 and 50.
  • Infants or children diagnosed with kidney problems can get stones.
  • Ethnicity is another factor that influences the stone formation. It is found that the Caucasians are at more risk than Africans.
  • Genetics also plays a role in kidney stones. So, if anyone in your family has the issue, then you need to maintain caution.
  • People with the history of the issue are more prone to getting it again compared to the others.
  • Some medication like the anti-seizure drugs, diuretics, and calcium-based antacids can also result in the stones.

Others major causes of the issue are:

  • Obesity
  • Dehydration
  • Diet in high protein, glucose or salt
  • Inflammatory bowel diseases
  • Hyperparathyroid Condition

Blood Tests

Your doctor may order a blood test. It will check the levels of uric acid, calcium, phosphorous, and electrolytes. The high levels of calcium and phosphorous mean kidney stone. Your healthcare provider orders the test to eliminate the other major complications due to kidney stones. The creatinine and the BUN (Blood Urea Nitrogen) test is also ordered to assess your kidney function.

In emergency cases, your physician can perform the ultrasound to understand the issues.

The contrast dye is not good for people with kidney problems. Some diseases can also trigger complications with the use of dye. So, you need to tell your doctor about your health issues. You also need to tell the details about the medicines you are taking. The radiologist must know the complete details before taking the scan. But, it is not an issue with people who have normal kidney function.
