Kidney stones can be tiny and difficult to see. Renal stones, another name for kidney stones, are hard deposits that happen inside the kidneys as a result of minerals and salts in urine forming crystals.

However, occasionally, it can enlarge to the size of a pea and get lodged in the ureter, which is the tube that carries urine from your kidneys to your bladder. This can obstruct urine flow and result in excruciating discomfort. In the worst situations, the pain is so bad that a visit to the emergency department is necessary, and surgery may be necessary as a result.

The recurrence rate of symptomatic stones is over 50% within 5 years of their first appearance, indicating that a specific group of patients at high risk may share common pathways in the process of stone formation that can be targeted for prevention. The prevalence of renal stones in India is approximately 12%.

What causes kidney stones to form?
In essence, kidney stones are tiny "stones" composed of various materials and minerals like calcium that build up in the urinary tract. Urine typically removes surplus salts, minerals, and waste items that come from the body's metabolic activities of constructing and disassembling proteins. 
Crystals, on the other hand, can form and combine with other elements to form a stone when there is an excess of waste and not enough liquid to dilute it.

What are some ways to avoid kidney stones?
It is advised to consume eight to ten glasses (or 64 to 80 ounces) of water per day as the primary remedy. Drinks like black cola are not allowed; however, tea, coffee, and juice are. Although the exact reasons to avoid dark colas are unknown, phosphoric acid, which is found in colas, is known to acidify urine and may contribute to the development of some types of kidney stones.

To attain appropriate hydration, it is advised to fill a measured container with water every morning and to sip on it throughout the day "with certain objectives in mind."

Studies indicate that the Dietary Approaches to Stop Hypertension (DASH) diet helps lower the risk of kidney stones, and a healthy diet can also be beneficial. The DASH diet discourages full-fat dairy products, tropical oils, and fatty meats since they are higher in acidity and instead encourages fruits, vegetables, and whole grains.
