Objective:To investigate the clinical value and feasibilty of the application of nephroscope's ultrasonic lithotresis combined with choledochofiberscope in postoperative residual bile duct stones.Methods:We had collected 35 patients who suffered from postoperative residual bile duct stones,18 cases were included in experimental group with performed with nephroscope's ultrasonic lithotresis and choledochofiberscope together;17cases in control group which performed with choledochofiberscope only.Choledochus sinus tract from postoperation were determined to be the operation channel.The operation time,stone clearance rate,adverse event incidence rate(during and after operation),would be abserved and analysed.Results:All patients were successfully completed operation;experimental group costed 47.83 minutes in average to finish the operation,but the time from control group rised to 62.76 minutes,experimental group is more more efficiently(P0.05);total clearance rate comed out with 74.29%,experimental group directed to77.78% and Control group fell on 70.59%(P0.05),were no statistically significant;the adverse event incidence rate during and after operation also showed nonsignificant difference(P0.05).Conclusion:The application of nephroscope's ultrasonic lithotresis combined with choledochofiberscope in postoperative residual bile duct stones is effective,feasible,environmentally friendly,which should be expanded to clinical treatment.
