The daily consumption of various nutrients as well as the dietary habits of 15 male and 15 female patients with renal stone were investigated ( their age ranged from 20 to 50 years ). The patients were interviewed about their intake through 24 hours dietary recall (3 days) and questionnaire regarding their food habits. Moreover, blood and urinary analysis were done for calcium, phosphorus, sodium, potassium, creatinine and uric acid.
Results regarding dietary intake showed that mean total protein, animal protein, phosphorus and sodium intake were higher among both males and females. On the other hand calcium and potassium intake by the patients ( male / female ) was lower than the recommended daily allowances (R.D.A.). while results of blood analysis showed that potassium and calcium for male and female, phosphorus (in female), sodium (in female), and creatinine (in male) were higher than the normal value. While mean blood analysis of uric acid (in male and female), sodium (in male), creatinine (in female) were lower than normal value. Mean value of urinary excretion for phosphorus and calcium (in all patients), potassium and creatinine (only in male) were higher than normal value but sodium and uric acid (in all patients), potassium and creatinine (in female) were lower than normal value. Therefore, the study indicates the important of dietary therapy in the manegement of renal stone patients. Diet should be modified particulary for dietary protein, calcium, sodium and phosphorus intake. Nutritional education program should be directed to individuals about the relationship between diet components and the development of renal stone.
