Hello,
The stones truck in the urethra or ureters need to be removed as early as possible because it carries the risk of hydronephrosis or pyonephrosis of the kidneys. I suggest you to consult a urologist immediately and get it immediately managed. You may need uerteroscopic removal of the stones.
I sincerely hope that helps. Take care.
Hi:
I had a similar thing happen to me 5 years ago. My stone got stuck about an inch or so from the tip. Eventually, it did come out on its own. But, I phoned my urologist and he said that if it did not come out on its own after a few days, OR if I was unable to urinate at any time (which would have been an emergency situation at that point), they would have to numb up my urethra with a local and go in and extract it.
I hope this helps and that you get relief soon.
