The Effects Of Dıetary Habıts On Urınary Stone Formatıon In Renal Stone Formers Compared Wıth Healthy Subjects

Abstract

Among 123 renal stone formers (38 female. 85 male) and 30 healty subjects, the daily intake of nutrient, such as calorie, carbohydrate, fat. calcium, phosphor, magnesium, sodium, vitamin C. oxalate, dietary fiber and purine was examined and compared with the recommended allowances in terms o f sex. height, weight and physical activity to evaluate the role of nourisment on stone formation. The results indicated that the consumption o f nutrients had been considerably high in the renal stone formers, with exceptions of magnesium and dietary fiber (p<0.001), while the latter group had had adequate calorie, carbohydrate, sodium and magnesium. Altough an increased intake o f other nutrients in healty subjects was detected, the amount had been less than the stone formers group. Both groups had had less dietary fiber than necessary, but the purine intake had showed significant increase. The oxalate intake had been higher in the patient group. In conclusion, depending on their habits, the renal stone formers had a higher incidence of stone formation than that of the healty subjects.
