Abstract:
This study aimed to compare the simultaneous use of two devices versus a single device through a single working channel in flexible ureteroscopy using a ureteral access sheath for single ureteral stones. Methods In a bench study, the time to (i) set laser fiber, (ii) exchange laser fiber and nitinol basket through working channel, and (iii) pull out the device from working channel were measured 10 times in each step. In a clinical study, 156 patients who underwent flexible ureteroscopy with a ureteral access sheath for a ureteral stone in middle and upper ureter between April 2019 and November 2021 were assessed. One device was used at a time for 79 patients (S‐Group) and two were simultaneously used for 77 (D‐Group). Surgical outcomes and complications were compared. Results In the bench study, the mean time to change from laser fiber to basket and from basket to laser fiber through the working channel were 26.1 ± 3.7 s and 23.6 ± 2.0 s ( p = 0.084), respectively, which were significantly longer than the laser setup time ( p 〈 0.001). In the clinical study, although the stone‐free rate was not significantly different between the groups (S‐Group 89.8%, D‐Group 93.5%; p = 0.412), the median operation time was significantly shorter ( p 〈 0.001) and the rate of postoperative stenting was significantly lower ( p = 0.002) in the D‐Group. There were no significant between‐group differences in intra‐ and post‐operative complications. Conclusion The simultaneous use of two devices through a single working channel is safe and could help save the time needed to exchange the laser fiber and nitinol basket.
