Treatment for smaller stones

If a small stone doesn’t pass naturally when you pee, your doctor may suggest Medical Expulsive Therapy - a medication that helps relax the ureter and make it easier for the stone to pass.

If this isn’t suitable for you, or if the stone still doesn’t pass, other treatments may be needed. These include breaking the stone into smaller pieces or removing it with a minor surgical procedure.
