Hi Jill, thanks for the question. You are an experienced patient who probably has a high pain threshold!!Stones over 5mm rarely pass out without some medical help
. You seem to be different if you have managed to pass such big ones in the past. As you may know the main hurdle will be the VU junction. You may be having a lax sphincter there which is helping. My sincere advice would be to get rid of the stone at the earliest no matter what it takes to do so. I hope you are taking all possible steps to prevent stone formation. Each time you have partial/ complete obstruction to your ureter
from the stone, your kidney
filters (nephrons) are suffering and the small amount of damage each time is cumulative (...small drops make an ocean!!). You might end up with premature kidney damage unless you act promptly. Best wishes.
