I had a kidney stent put in back in August because I was hurting in my back and my Urologist couldn't find out why so he put a stent in just to be on the safe side. Well Its been 4 months since 3 1/2 months since he removed it and I am still hurting like before and have been since he removed the stent. Could the stent have caused some damage to my kidney? He told me that the tube from my kidney to my bladder was inflamed at the time
