Magnesium ammonium phosphate (a.k.a. struvite or "triple phosphate") crystals:
 - Formation promoted by alkaline urine
 - Seen in UTIs by urease-producing organisms (e.g. Proteus, Klebsiella)
Calcium oxalate dihydrate crystals:
 - Formation is largely independent of urine pH
 - Not suggestive of any specific systemic disease
Calcium oxalate monohydrate crystals:
