Whether urinary tract stones can be discharged is mainly based on the size of the stones, usually if the diameter of the stones is <0.6cm or less, this case can have a chance to discharge, with more water, more exercise can promote the discharge of stones by holding urine. You can also take some auxiliary medications, such as Halle, which has the effect of dilating the ureter and will also help the discharge of stones. If the stone is more than 0.6 cm, we recommend extracorporeal lithotripsy or minimally invasive surgery to break up the stone. Generally speaking, the size of the stone will determine whether it can be discharged or not, but stones under 0.6cm can be discharged with some chance. The above questions are for reference only. Please refer to the doctor's instructions for specific medication and treatment.
