[|Human|] I am 32 year old female that had a lithrotripsy done three weeks ago on a 5mm stone and now I have blood and pus in urine and another stone doctor is going to explore it in the morning to see if it is lodged in uretha what can be causing all of this now
[|AI|]  Hi, Thanks for writing in. Most persons pass blood in their urine after the lithography procedure. This is normal and should clear after several days to a week. Blood and pus can be due to injury of ureter by dislodged smaller fragment and subsequent infection. Lots of fluids should be taken to encourage the flushing of any gravel remaining in the urinary system. Treated persons should follow up with a urologist in about two weeks to make sure that everything is progressing as planned. You may need to take a course of antibiotics to control infection.
