Hi Goomby,
It's your friendly urologist here.
Typically, I do not remove non-obstructing stones either. I will sometimes remove them if I suspect that they are associated with infection, there is a solitary kidney, or they are causing pain (this is very rare).
So yes, talk to your urologist about it and tell him that you are willing to accept the risk and temporary discomfort of the procedure to get rid of the stone.
Thanks
Dr. Holland
My friend, I have not had any experience personally with what you have described with losing a kidney and all, but I have a good friend who lost one of his kidneys due to an extremely large kidney stone and the damage it caused, years ago. All I can tell you is that with only one kidney left, he doesn't take any chances with any kidney stone he gets in the kidney he has left. Stones are removed quickly and he and his Urologist stay in close contact during any period involving a kidney stone. I wish you the best and please let us know how you make out.
