Blood in Urine
Blood in the urine can be a very common sign in those people with stones in the urinary tract or kidney. This condition is also known as hematuria. In general, the blood would show up in your urine and make it turn brown, pink, red, and dark. It is caused in more advanced stages when the infection triggered by kidney stones damages some blood vessel cells and causes blood to leak. However, the blood cells can be sometimes too small to notice with your eyes. In this case, a microscope can be used to detect the issue. [3]
