Kidney stones pictures

The most common type of kidney stone is composed of calcium oxalate crystals, occurring in about 80% of cases,and the factors that promote the precipitation of crystals in the urine are associated with the development of these stones.

The formation of struvite kidney stones is associated with the presence of urea-splitting bacteria, most commonly. These organisms are capable of splitting urea into ammonia, decreasing the acidity of the urine and resulting in favorable conditions for the formation of struvite kidney stones. Struvite kidney stones are always associated with urinary tract infections.
