In Jan of 2016, my ureter was completely closed, my kidney had infection and was very inflamed. The ureter had become constricted and looked like a z shape. They did surgery, cleaned out the pus, etc, and placed a stint in my ureter for about 2 mos. This was a year ago, although, I suffered for probably 2 years. They placed me on tamsulosin 0.4 mg, and I remain on it still. My question is this still necessary to be on the meds? I will say I have not had another incident since then, although I do have right side back aches on occasion on the side of the incident. What does the medication do for me? Is there a good reason to continue it this long?
