What is the significance of amorphous crystals in urine?

What is the significance of amorphous crystals in urine?

The presence of amorphous crystals is generally of little clinical significance. Their formation is caused by a combination of factors, including decreased urine volume combined with changes in urine pH and often the presence of large quantities of uric acid (meat consumption), or calcium (dairy products) in the diet.

What is the clinical significance of triple phosphate crystals in urine?

Triple phosphate crystals are seen in patients with urinary tract infections caused by urea-splitting bacteria, such as Proteus mirabilis, and are frequently found in the urine of patients with infected calculi (struvite stones).

What is the clinical significance of urinalysis?

A urinalysis is used to detect and manage a wide range of disorders, such as urinary tract infections, kidney disease and diabetes. A urinalysis involves checking the appearance, concentration and content of urine. Abnormal urinalysis results may point to a disease or illness.

How do you prevent crystals in urine?

The most effective way to prevent urine crystals is to drink more water and stay hydrated. This helps dilute the chemical concentrations in the urine, preventing crystals from forming. You can also make certain changes in your diet.

What causes cystine crystals in urine?

What causes cystine stones? Cystine stones are caused by a rare disorder called “cystinuria.” The disorder causes a natural substance called “cystine” to leak into your urine. When there is too much cystine in the urine, kidney stones can form.

What do struvite crystals look like?

Struvite (magnesium ammonium phosphate) is a phosphate mineral with formula: NH4MgPO4·6H2O. Struvite crystallizes in the orthorhombic system as white to yellowish or brownish-white pyramidal crystals or in platey mica-like forms. It is a soft mineral with Mohs hardness of 1.5 to 2 and has a low specific gravity of 1.7.

Why do we need to examine the urine sediment immediately after decantation?

Urine should be examined as soon as possible after collection, because artifacts will occur in the urine over time (cells lyse, crystals form in vitro). If a delay is anticipated before analysis, the urine should be refrigerated.
