Follow On: Calcium oxalate crystals are mineral deposits that cause urinary tract infections in pets. Apart from calcium oxalate crystals, dogs are also known to suffer form struvite stones that cause similar urinary tract infections. Pets suffering from calcium oxalate crystals have acidic urine. If these crystals donât pass out in the urine, they eventually come together and form stones.
Crystalluria indicates that the urine is supersaturated with the compounds that comprise the crystals, e.g. ammonium, magnesium and phosphate for struvite. Crystals can be seen in the urine of clinically healthy animals or in animals with no evidence of urinary disease (such as obstruction and/or urolithiasis). However, some crystals can be pathologically relevant in certain circumstances (see example of ammonium biurate below). Note that crystals may not form in all urine supersaturated with these compounds.
