Hello doctor, I have 5.5 mm stone in my right distal uretar, 2cm proximal to vu junction. Last month i had ct scan which shows above report and my urologist given urimax for 15 dyas. Today i taken a ultra sound and the stone is of same size and not moved a bit. I am having very minimal pain and cramp. Pain is sometime more in night. This pain was there from 2 months but got to know about stone in last month ct scan. I had one sergery or uretic stone 3 year back also. Now i dont want it again. Please advise if i can wait more time for it to pass. How long i can wait.
