The requirements for biliary lithotripsy include good gallbladder function, no other complications of the gallbladder, and certain requirements on the number and size of stones. 1. Good gallbladder function: Before performing biliary lithotripsy, the function of the gallbladder must be evaluated first, and biliary lithotripsy can only be considered if the gallbladder is functioning well. 2. No other complications of the gallbladder: the implementation of the surgery requires that the gallbladder does not have acute inflammatory lesions, and there are no secondary complications, such as choledocholithiasis, secondary pancreatitis, etc. Otherwise, it is not suitable for biliary conservation. 3. The number and size of stones: the number of stones should be less than three, and the size of stones should be moderate. 4. Strong willingness of the patient to preserve the bile and remove the stone: because of the high recurrence rate of stones after surgery and may increase the risk of malignant changes, nowadays biliary lithotripsy surgery is not advocated. If the patient has a strong desire for biliary lithotripsy, he or she should sign an informed consent form and be willing to bear the possible consequences. Not every patient with gallbladder stones is a candidate for biliary lithotripsy, and the decision should be made only after evaluation by a physician. The decision to use biliary lithotripsy should be made only after evaluation by a physician, and the treatment plan should be adjusted as soon as the patient is found to be ineligible during the procedure.
