Several misconceptions about the treatment of urinary stones: 1, stones are not painful, no treatment, stones can slowly grow, serious patients suffer from loss of kidney function. 2, stones are not as terrible as tumors, treatment does not matter, some patients with stones for decades, and eventually uremia and then treatment effect is poor. 3, small kidney stones due to gravity, mostly located in the lower renal calyces, only by drinking more water activity medication, the effect of stone removal is poor. 4, after the treatment of stones think that everything is fine and do not pay attention to prevention, a few years later there is a recurrence of stones.
