There are many types of biliary stents, both domestic and imported stents; both plastic stents and metal or alloy memory stents. The specific costs of stents of different types and origins are different, but, overall, they are still very expensive. Generally, imported stents as well as metal stents are more expensive, and the price is about 10,000-20,000 yuan; while domestic stents and plastic stents are relatively cheaper, and the approximate price is about 5,000-8,000 yuan. It is necessary to choose different types of stents for treatment according to the patient’s specific condition and economic conditions. At present, stent placement, which is usually done under intervention, costs about 20,000-30,000 yuan overall. Some of them can be reimbursed through medical insurance, which can further reduce the overall cost. Plastic stents generally last about six months, while metal stents last longer, up to about 1-2 years.
