crystalluria

[kris′təloo͡r′ē·ə]
the presence of crystals in the urine. The condition may be a source of urinary tract irritation; adequate intake of alkali can prevent it. However, crystals are commonly found in urine and are usually insignificant. Cystine crystals, or uric acid crystals, precipitate in acid urine. Phosphate, or oxalate, crystals precipitate in alkaline urine.

Our study for the first time confirms that in hyperoxaluric animals, rottlerin treatment leads to reduced renal cellular injury, diminished crystalluria, reduced NADPH oxidase activity as well as a decline in translocation of PKC<5 from cytoplasmic fraction to the membrane and mitochondrial fraction, suggesting an inhibition of PKC[delta] activity.
In addition, they reported that crystalluria was more important in lithiasis subjects compared with healthy non-fasting patients.
Apart from symptomatic improvement, one can monitor therapy with regular urinalysis to rule out calcium crystalluria, which may be suggestive of hypercalcaemia Patients who cannot be monitored regularly in an ideal manner should be prescribed lower, but more frequent doses of oral vitamin D3.
