The discharge time of ureteral stone after lithotripsy is related to the location of the stone, the degree of ureteral stenosis, the effect of treatment, etc. Generally speaking, it can be discharged in 1~2 weeks after lithotripsy. If the stone is small and brittle after lithotripsy, it can be discharged in about one week by drinking a lot of water and exercising appropriately if the ureter is clear, but some of them may take about two weeks to be discharged. If the stone is large and hard after lithotripsy, the possibility of its expulsion will be reduced. If the stone is not discharged in about two weeks or even remains in its original position despite active rehabilitation, another lithotripsy treatment may be necessary. Therefore, after lithotripsy, you should drink a lot of water, appropriate exercise, etc. to promote the expulsion of stones, and after two weeks, you should go to the hospital in time for a follow-up examination.
