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.
Percutaneous nephrolithotomy (tunnel surgery). A surgical procedure for stones that cannot be treated with lithotripsy or endoscopic procedures. It involves the removal of a stone through a thin tube tunneled through a small incision in the back into the kidney.he shock waves break a large stone into smaller stones that will pass through the urinary system. Lithotripsy allows persons with certain types of stones in the urinary system to avoid an invasive surgical procedure for stone removal.
