The interrelation of calcium oxalate crystalluria and ionic product of calcium oxalate in renal calculus cases.
Pak J Med Res Jan ;39(3):121-2.

The incidence of crystalluria in random urine samples of patients and subjects was measured microscopically. The overall incidence of calcium oxalate crystallurisa was high in patients but not significant. The ionic product of calcium oxalate was significantly high in patients as compared to controls. The 24 hours urinary calcium oxalate ionic product and crystalluria excretion was higher in patients than in controls, which may show the role of some inhibitors of crystal formation and its growth in control groups. Therefore, it is suggested that some urinary ions retard the mineralizing and crystallisation rate of calcium oxalate.
