Abstract

Abstract:

Objective

To investigate the effect of preoperative indwelling double J stent for flexible ureteroscopic lithotripsy.

Methods

Ninety-eight patients with renal calculi or ureteral calculi treated by flexible ureteroscopic lithotripsy in our hospital from January 2014 to August 2015. The patients were divided into two groups according to whether received indwelling double J stent 3-5 days before operation. The difference of successful rate, 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 [(44±13) min vs (54±12) min, P<0.05], but got more expensive hospitalization cost [(20 183±3 426) yuan vs (15 655±3 542) yuan, P<0.05]. There were no significant differences in the success rate [98%(49/50) vs 89.6%(43/48), P>0.05], postoperative complications and postoperative hospitalization time between the two groups.

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.
