10 Signs of Kidney Stones
4. Dark or Red Urine
Hematuria is the medical term used to describe blood in the urine. When a patient is able to see blood in their urine, this is called macroscopic hematuria. On the other hand, some patients may have blood in their urine but the amount is so low that it is only visible during a urine analysis, this is called microscopic hematuria.
More than 50% of the patients suffering from kidney stones have either macroscopic or microscopic hematuria. As the stone passes through the urinary tract, it may damage it, causing blood to appear in the urine.
