This is not unlike the way high blood sugars or high cholesterol set the stage for diabetes and heart disease. Change in urine pH promotes the formation of crystals because of changes in solubility and resulting precipitation. The kidney helps in the maintenance of pH by the excretion of hydrogen ions into the urine while reabsorbing the bicarbonate ions from the urine. Women: 2.6 to 6.0 mg/dl.
