Bile duct stones are typically removed using endoscopic retrograde cholangiopancreatography (ERCP), a minimally invasive procedure that combines x-ray and upper endoscopyâan exam of the upper gastrointestinal tract, consisting of the esophagus, stomach and duodenum (the first part of the small intestine)âusing an endoscope, which is a lighted, flexible tube, about the thickness of a finger.
This procedure is most effective for stones in the kidney or upper ureter. Lithrotripsy uses an instrument, machine, or probe to break the stone into tiny particles that can pass naturally.
