Q: I am a 55 years old male, having an 11.0 mm sized stone in my left kidney that is not causing any pain. Is there any medication available for its removal? At present, I am taking Cystone twice on a daily basis.

A:Kidney stone, once formed, cannot be removed (dissolved) by any medicine except for surgical intervention. On the other hand, one could have a spontaneous passage of stones, which depends upon the size and location of the stone. Stones of <5 mm, if located in lower portion of the urinary tract namely ureter are known to spontaneously pass more often. Those kidney stones, which are asymptomatic, causing no problems including obstruction or pain symptoms are left unattended while continuing with the treatment intended to prevent recurrent stone formation in future.
