Hi and thanks for the query,
Not all kidney
stones cause symptoms. The symptoms are actually related to the size of the kidney stone, the location of the stone, type of stone and the duration of the stone. many people in the general population have small stones and present with no symptoms. Its there normal for a CT scan
to detect stones without any symptoms. It becomes a worry when symptoms like pain, urination difficulties, infections and kidney failure come into play. However, regular clinical, biological and radiologic monitoring by your treating physician remains well indicated.
Thanks and best regards,
