| Objective: To investigate the effect of preoperative indwelling double J stent for the operation of flexible ureteroscopic lithotripsy success rate,operation time,etc.Methods: 98 patients with renal calculi or ureteral calculi treated by flexible ureteroscope lithotripsy in our hospital from January 2014 to August 2015.The patients were divided into two groups according to whether recived indwelling double J stent 3-5 days before operation.The difference of successful rate of operation,operation time,postoperative complications,hospitalization time and cost were analyzed.Result: The operation time of the group received indwelling double J stent 3-5 days was shorter,but got more expensive hospitalization cost.There was no significant difference in the success rate,postoperative complications and postoperative hospitalization time.Conclusion: The preoperative indwelling double J stent can significantly shorten the operation time of flexible ureteroscopy,but the effect on flexible ureteroscopy success rate needs further study. |
