Efficacy of the direct grasping technique using pean forceps under fluoroscopy to replace ureteral stents in women

抄録

Purpose : To evaluate the efficacy of the direct grasping technique using pean forceps under fluoroscopic guidance for ureteral stent replacement in women. Methods : Between April 2018 and September 2020, 28 female patients underwent ureteral stent replacements at our facility, and 184 stent replacement procedures were performed. A total of 127 stents were replaced using pean forceps under fluoroscopic guidance (pean forceps group), and 57 stents were replaced using the cystoscope (cystoscopy group). Clinical characteristics and surgical outcomes were compared between the groups. Results : All stents were successfully replaced. There was a statistically significant difference in the procedure time between the two groups (median [interquartile range], pean forceps group : 10.8 [8.2–13.9] minutes vs. cystoscopy group : 15.8 [11.1–20.9] minutes, P < 0.001). There were no intraoperative complications in either group and no difference in the incidence of postoperative complications (pean forceps group : 1.6% vs. cystoscopy group : 1.8%, P = 1.000). Fluoroscopy time was longer in the pean forceps group, although this difference was not statistically significant (pean forceps group : 38.9 [22.6–60.1] seconds vs. cystoscopy group : 33.0 [20.0–48.9] seconds, P = 0.0558). Conclusion : The direct grasping technique using pean forceps under fluoroscopy may be a beneficial alternative to cystoscopy for ureteral stent replacement in women. J. Med.
