Introduction

Objective: To investigate the impact of preoperative double J (DJ) stent insertion on outcomes of retrograde semi-rigid ureteroscopy (URS) in patients with upper small and medium sized ureteral stones.

 

Materials

Between April 2018 and September 2019, we retrospectively reviewed the medical register of Hillel Yaffe tertiary reference Centre (HYMC) for patients who had undergone retrograde semi-rigid URS for urolithiasis. Patients were separated into two groups depending on whether they underwent DJ stent placement before URS (Group A) or not (Group B). Operating time, stone clearance rate, number of insertions of post-operative DJ stents, duration of post-operative stents, complication rate and requirement for repeat URS were compared between groups.

 

Results

,

318 procedures undertaken in 290 patients were included (Group A, 83 procedures in 80 patients; Group B, 235 procedures in 210 patients). By comparison with the non-stented group, patients in the preoperative DJ stented group had a lower complications, required less postoperative DJ stent insertion, had shorter duration of postoperative DJ stent and needed less complementary procedures. Nonetheless, there was no difference in operating time and the clearance rate between the groups.

Conclusion

Facilitated semi-rigid ureteroscopy with upstream preoperative DJ stenting for small and medium size ureteral stones had favorable outcomes compared with primary ureteroscopy
