How much can kidney stones be discharged by themselves

Clinically, patients with kidney stones, check the urinary system color ultrasound or CT, stone diameter less than 6mm below, you can choose conservative treatment, that is, more water, frequent urination, waiting for observation of independent stone discharge. But the premise of conservative treatment is to ensure that there is no urinary system infection, so patients should check urine routine, but also to maintain the entire urinary system unobstructed. If there is ureteral stricture or urethral stricture, even if the stone is conservative, the stone cannot be discharged by itself, and it may form a local encapsulated stone with the urethral stricture, resulting in urinary system hydrops. Therefore, in clinical examination, if the diameter of simple stones is less than 6mm, conservative stone discharge can be selected, but it should be fully evaluated and conservative stone discharge should be selected. For conservative treatment of stones more than 2 weeks still can not be discharged, at the same time complicated with urinary system ponding, urinary tract infection, patients should choose active treatment.
