I have a 8mm kidney stone that has moved from the mid distal right ureter to right ureter just proximal to the uterovesicular junction. there is mild fullness of right ureter. bladder is unremarkable. I have passed stones this large in the past and I am curious if this recenct ct scan shows the stone has made progress in moving down on it s own. I do not want to have a lipotripsy if i can avoid it... Thank-you Jill
Hi Jill, thanks for the question. You are an experienced patient who probably has a high pain threshold!! Stones over 5\u00a0mm 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 Chat Doctor.  You might end up with premature kidney damage unless you act promptly. Best wishes.
