Urine consists of water, urea, uric acid and ions like calcium, sodium, oxalate and potassium. However, when some of these constituents such as uric acid, calcium and oxalate ions increase in the urine. They bond together forming kidney stones or renal calculi. One of the most common kidney stones is calcium oxalate. So, can I use it to build my house? Just listen. Generally, the kidney stones are small. Hence, they pass unnoticed through the urinary tract. However, sometimes these stones become so big that they start to scratch walls of the urinary tract. May block the path of the urine, thus causing immense pain.
