I had ureteroscopy due to which I have mild ureter stricture in my left ureter. The ureter wall is thickened to 3-4mm. At times i have difficulty in passing urine and sometimes it pains in after urinating. Hydroureter over the thickened wall. I don't feel pain in kidney or ureter but frequent urination and pain after urinating is the problem. Any medications? Do I need to worry, will it get worse or will it heal itself.
