Why does the body get kidney stones and how do they even form?

Question

I’ve tried searching this but I’m legitimately confused as to why and how kidney stones come to exist in somebody?

Answer 1

Kidney stones is solid urea. Lack of water causes kidney stones. Urea being what makes pee yellow and smell pungent.

EDIT: Turns out it might not be urea? Concept is the same in the end. Stay hydrated or kidney stones.
