Answer 1

Renal calculi refers to the condition in which certain hard structures or calcified structures are present in the bean-shaped organs responsible for the filtration of toxic substances from the blood and formation of urine.

Complete answer:
Renal calculi are the conditions in which small hard structures or stones are formed within the kidneys or the urinary tract. This condition is also known as nephrolithiasis or urolithiasis and in this disease, a solid piece of material is often found.
This condition occurs mostly as a combination of genetics and environmental factors.

Additional Information:
-Risk factors for renal calculi include high calcium levels in urine, obesity, certain food materials, and medications, and calcium supplements.
-The stones are formed when the minerals are present in a higher concentration than usual.
-Diagnosis is usually done based on symptoms, urine testing, and blood tests.
-Between 1 to 15% of the world population is affected by renal calculi at some point in their lives.
So, the correct answer is, “Stone is formed in the kidney.”

Note: -Usually, small stones pass through the system into the urine and do not show any symptoms. If the size of the stones is large, they can be stuck in the ureters and may cause pain.
-For people who developed stone, they are recommended to diet with lower minerals and are advised to drink at least 2 litres of water daily which may cause the dissolving of the stones and easy removal.
-In severe cases of blockage, they may be required to be surgically operated and in extreme cases, they may even lead to death.
