Urinary S/O High Dilution effectively dissolves struvite uroliths.

Diluting urine decreases the urinary concentration of struvite and calcium oxalate crystals. Greated urinary volumes also ensures regular bladder wash-out.

Low RSS (Relative Super Saturation) diets encourage an undersaturated urinary environment, unfavourable to the development of struvite and calcium oxalate crystals.

Magnesium is a component of struvite (magnesium ammonium phosphate) uroliths.
