*Amorphous uratePinkish granular appearanceThey have no clinical significance
*Na-urateNeedles-like appearanceThey have no clinical significance
*Hippuric acid (*)Rare crystalThick or thin needlesThey have no clinical significance
*Ca-sulfateRare crystalThin needlesThey have no clinical significance
*Abnormal crystals
*TyrosineVery fine, highly refractile needles occurring in clustersClinical significance - Severe liver disease - Tyrosinosis
*CystineColorless, refractile hexagonal plates, which appear singly, on top of each other, or in clustersClinical significance: - Congenital cystinosis - Congenital cystinuria
*LeucineOily, highly refractile, yellow or brown spheroids with radial and concentric striationsClinical significance - Maple syrup urine disorders - Liver disease Leucine and tyrosine crystals are often present together in the urine of patients with liver disease
*CholesterolLarge, flat, transparent plates with notched cornersClinical significance - Excessive tissue breakdown - Nephritis and nephrotic condition
*Drugs, X-ray dye, and others
* Triple phosphatePrisms with 3-6 sides, resemble coffin lidsSome times in atypical feathery or fern appearance
