Most common kidney stones are made up of

• A. Magnesium phosphate
• B. Calcium oxalate
• C. Uric acid

Answer 1

The correct option is B Calcium oxalate

There are four main types of kidney stones. Calcium stones are the most common type of kidney stones. They are usually made of calcium and oxalate (a natural chemical found in most foods) but are sometimes made of calcium and phosphate. Uric acid stones form when urine is often too acidic.

So, the correct option is 'Calcium oxalate'.
