I had a very large kidney stone blasted through lithotripsy. I was asleep for that procedure so no problem. When I awoke I learned I had a ureter stent which had to be removed in one week. I knew nothing about stent removal so I turned to the internet. This was a HUGE MISTAKE. Everything I read scared me more and more. Well, I have had the stent removed and it was nothing!! I coughed and it was out! So, the moral of this is don't assume everything you read, on the internet, is correct.
