Calcium oxalate crystals are an indication that there may be kidney stones in one or both kidneys. Kidney stones up to 5 mm in size can pass through the urinary tract, though with significant discomfort. Bladder stones can also be formed with the calcium oxalate crystals; however, kidney stones are more likely.
If the stone is blocking some part of the outlet of the kidney or the ureter, it will cause obstruction and backflow of urine. The pressure effects of such obstruction will cause significant damage to the kidney and this will be further complicated if there is an infection. A jagged stone stuck in the ureters can cause significant trauma to the mucosa and can cause blood to appear in urine.
Ensure that you keep fluid intake over 2000 ml per day and avoid irritants such as caffeine, alcohol, pepper, etc.
