[Staghorn lithiasis in an infant related to mineral water high in calcium].
Staghorn lithiases in the infant are rare. We report a staghorn lithiasis related to high calcium intake due to the exclusive use of the mineral water Hépar.


METHODS
In an eight-month-old infant, an abdominal film performed for repeated urinary symptoms showed a right-sided staghorn lithiasis. Past history revealed that his diet had contained as high as four times the recommended daily intake for calcium (1,750 mg) related to the exclusive use of Hépar mineral water. The latter had been discontinued one month prior to admission. Excessive doses of vitamin D (1,480 U/day) were given at this time. Blood tests were normal. Treatment combined surgical removal of the stone by right pyelolithotomy, and three extracorporeal lithotrity courses. A postoperative infection had a simple course after antibiotics.


CONCLUSIONS
This staghorn lithiasis is the second case report to complications associated with long-term exclusive intake of Hépar mineral water in an infant. It has been likely favored by excessive doses of vitamin D. It emphasizes the danger of the exclusive use of high-calcium mineral water.
