    Abstract:
    In order to better understand the role of diet in etiology of urolithiasis, 84 oxalo-phospho-calcic-lithiasic patients (52 men, 32 women) have been studied by a nutritional week-interview and by urinary and blood testing. Diet data were compared to an ideal standard. Total caloric intake was 2428 +/- 651 calories/d; this intake is high in 7% women and 40% men. 79% out of patients are fat. Protidic intake is 87 +/- 21 g/d higher than 1 g/kg/d in 84.5% of patients. Lipids are high in 38.9 +/- 7%, glucid are low in 45.3 +/- 7%. Calcium intake is 934 +/- 406 mg/d, sodium intake is 12.9 + 3 g/d. Water intake is 2305 +/- 759 ml/d. Different groups of patients are studied: a) 21 patients with mean age of 43 +/- 12 years have recurrent lithiasis (R). This group is compared to 48 patients with 37 +/- 44 years who have a single lithiasis. Half of (R) patients have hypercalciuria, hyperphosphaturia and hyperoxaluria. Diet study is no different between these two groups. b) Other groups are studied: 21 have hyperophosphaturia (HPU) without hypophosphoremia and they have hypercalciuria, hyperuraturia and high urinary urea; diet shows higher glucicid and potassium intake than group with normal phosphaturia; 23 have hypercalciuria (HCU) and high uraturia and phosphaturia: diet study shows no difference with a group with normal calciuria. 21 have hyperoxaluria (HOU): diet study of a normal oxaluric group shows higher lipid intake, lower glucidic and calcium intake; 22 have hyperuraturia (HAU) and higher urinary urea, sodium and potassium than normouraturia group: in this group potassium intake is higher.(ABSTRACT TRUNCATED AT 250 WORDS)
