Choledochal stents usually do not need to be taken out again, but plastic stents do need to be removed. The main function of the choledochal stent is to dilate the bile ducts, which can keep the bile ducts open and allow bile to drain smoothly. Especially for patients with bile duct stenosis or stones, if it is removed, it can cause re-stenosis of the bile duct and lead to corresponding lesions. By placing a biliary stent in the location of the corresponding narrowing of the bile ducts, the bile ducts can be well dilated to treat the corresponding diseases. At the same time, whether or not the stent is removed is also related to the material of the stent. If a plastic stent is used, it can be removed, and if it is made of metal, it does not need to be removed. In most cases, choledochal stents do not need to be removed, but you should consult with the relevant doctor for specifics and be guided by him. If the stones are found to have been eliminated and there is no infection or other problems during the follow-up examination, the stent can be removed under the guidance of the doctor, but in other cases, it is usually not necessary to remove the stent.
