Struvite is of organogenic origin and this type locality example is formed in manure pits. Location: Nicolaikirche, Hamburg, Germany. Scale: Specimen Size 1 x 1 x 1 cm. © Tom Loomis / Dakota Matrix Cat urine (struvite) crystals are microscopic minerals made of ammonium, phosphate, and magnesium.

The formula tells us that struvite crystals are created when magnesium, ammonia, and phosphate combine in water in a mole to mole to mole ratio of 1:1:1. Struvite stones are one of the most common bladder stones in dogs and cats. They typically form because of urinary changes that happen when bladder infections occur. However, according to veterinarians at the Marva Vista Animal Clinic in Los Angeles, struvite crystals require an alkaline pH in order to form; they cannot form in acidic urine. Struvite is a crystal that occurs naturally, mostly in places such as wastewater treatment plants (WWTP), confined animal feeding operations (CAFO), food processing, and other industries where magnesium, ammonia, and phosphate are present. Magnesium ammonium phosphate crystals, literally the solid phase of a triple salt, were described by Struve, who found them in caves, and gave his name to them: struvite.157 These stones form only when the kidneys are colonized by bacteria that possess the enzyme urease, which hydrolyzes urea to ammonia and CO 2. Struvite crystals are one type of urinary blockage that pet cats can develop.

Combine them with certain bacteria, however, and a stone is When crystals aggregate and grow into calculi before being voided, uroliths form. Feline uroliths form in the urinary bladder (most commonly) or renal pelvis. They Variation in urine characteristics over time can result in more than one crystal type within a The most common urinary stones in dogs are composed of struvite. Struvite stones account for 15% of renal calculi. They are associated with chronic urinary tract infection (UTI) with gram-negative, urease-positive organisms that Struvite is a white crystal which is formed in neural or mild alkali conditions. Nucleation and crystal growth are two steps for struvite crystallization from generation temperature has only a minimal effect on struvite solubility.
