A survey of the diet was made in 61 patients with urolithiasis (10 females and 51 males) for successive two weeks. The results were compared with the results from the National Nutritive Survey and the Daily Nutritive Requirement in Japanese. There was no difference in the ingested amount of calories, total protein, fat, carbohydrate, phosphorus, and sodium. However, the ingested amount of calcium (Ca) was unexpectedly small, and the trend was remarkable especially in the patients who received the guidance for restriction on Ca. Futher more, it was found that ingested magnesium was of a very small amount because the ingestion of vegetables was insufficient. Nevertheless, the ingested amount of Ca and total protein was large in some patients.
Comparative study of excretions in the urine and the ingested nutriment on the same day was made. There was no relationship of any nutritive element to Ca excretions in the urine. The male patients were classified into the hypercalciuria group (250mg or more/day) and normocalciuria group. Comparison of the two groups in relation to the ingested nutriment revealed a significant increase of ingested total protein in the hypercalciuria group. Further more, it was suggested that the effect of ingested total protein on Ca excretions in the urine was great.
In view of these results, the following have been thought to be important as the first step to prevent recurrence of urolithiasis; a survey of the diet in each individual case and the guidance of the diet suitable for each individual case on the basis of the survey results.
