This means there are stones in the gallbladder which may be asymptomatic at present, but may become problematic later on.
In case the stones are small <1cm and radiolucent on an X-ray, you can consider taking UDCA 300mg BD just after lunch and dinner.
Stones bigger than that might require invasive methods should the symptoms develop.
Next Steps
Consult a General Surgeon.
