[Hyperhydration with low mineral Rocchetta water after extracorporeal lithotripsy].

Both prophylaxis and stone-free status after ESWL are most important goals in treating urinary stone disease, because his high social cost. In order to this situation, we matched two homogeneous groups of patients that underwent ESWL because renal stones: during a one year follow-up with several US controls, daily 1.5 litres of low mineral content water was drank by I group patients; vice versa, daily 3 litres (1st ten days) and afterwards 2 litres of Rocchetta low mineral content water was drank by II group patients. This last kind of approach led to a significant improvement in stone fragments elimination time, in inferior calix stone cure and in stone recurrences rate. So we conclude that hyperhydration using right low mineral content water, is a simple and cheap way to improve both treatment and prophylaxis of urinary stones.
