Relative risk factors of renal stone formation

This study had been conducted to define the relative risk of renal stone formation in terms of urinary risk factors, urinary calcium, uric acid, urine volume and pH were found to be within normal limits in stone formers. This suggest that factors play a minor role in stone formation especially calcium and uric acid. Stone formers excreted low urinary magnesium and citrate, a know inhibitors of calcium oxalate stone formation. The low urinary citrate which is induced by low serum potassium is considered as a major risk factor of renal stone formation as its deficiency highly increased the risk of urolithiasis. In general, the lower the urinary crystal formation and growth-inhibitors the higher will be the risk of stone formation
