What exactly are struvite stones?

Struvite stones are a subtype of urinary stones. They are differentiated according to their constituents. Urinary stones (also called urate stones) are formed by a crystallization process in the urine. These crystals can subsequently aggregate and then form urinary stones. 

They are formed by various substances that are excreted during urination. These urine crystals are located in the lower urinary tract or the urinary bladder, and more rarely in the kidney.

Nutrition
