“…These findings support the results of other workers who have shown that a low calcium diet increases the excretion of oxalate [15,16]. Indeed, the potential danger of dietary calcium restriction has been demon strated by Bataille et al [17] who reported an increased probability of forming stones in patients with certain types of hypercalciuria when following such a diet [17], Thus, these studies suggest an apparent protective effect of dietary calcium. It therefore seems feasible to advise stone formers to increase their dietary intake of cal cium.…”

Calcium oxalate kidney stone formers are invariably advised to increase their fluid intake. In addition, magnesium therapy is often administered. Recently, a prospective study showed that a high dietary intake of calcium reduces the risk of symptomatic kidney stones. The present study was performed to test whether simultaneous delivery of these factors – high fluid intake, magnesium ingestion and increased dietary calcium – could reduce the risk of calcium oxalate kidney stone formation. A French mineral water, containing calcium and magnesium (202 and 36 ppm, respectively) was selected as the dietary vehicle. Twenty calcium oxalate stone-forming patients of each sex as well as 20 healthy volunteers of each sex participated in the study. Each subject provided a 24-hour urine collection after ingestion of mineral water over a period of 3 days; after a suitable rest period the protocol was repeated using local tap water (Ca: 13 ppm, Mg: 1 ppm). In addition, 24-hour urines were collected by each subject on their free diets. The entire cycle was repeated at least twice by each subject. Several risk factors (excretion of oxalate; relative supersaturations of calcium oxalate, brushite and uric acid; calcium oxalate metastable limit; oxalate:magnesium ratio and oxalate:metastable limit ratio) were favourably altered by the mineral water and tap water regimens but the former was more effective. In addition, the mineral water protocol produced favourable but unique changes in the excretion of citrate and magnesium as well as in the relative supersaturation of brushite which were not achieved by the tap water regimen. To the contrary, tap water produced an unfavourable change in the magnesium excretion. The group which benefitted most were male stone formers in whom 9 risk factors were favourably altered by the mineral water protocol. It is concluded that mineral water containing calcium and magnesium, such as that used in this study, deserves to be considered as a possible therapeutic or prophylactic agent in calcium oxalate kidney stone disease.
