Abstract：Objective To explore the applicability of virtual endoscopic reconstruction technology in the treatment of pilot kidney stones using ureteral flexible ureteroscopy.Methods A total of 32 pilots who underwent ureteral flexible ureteroscopy for kidney stones at the Urology Department between January 2021 and February 2024 were selected for this study,who were randomly divided into two groups using a random number table method:the control group(16 cases)and the experimental group(16 cases).The control group underwent traditional CT imaging for stone localization and subsequent ureteral flexible ureteroscopy while the experimental group used virtual endoscopy reconstruction technology for preoperative stone localization and intraluminal surgical path planning.During surgery,the planned path was followed for ureteral flexible ureteroscopy.The age,stone length,stone location,intraoperative stone localization time,surgical durations,and postoperative complications were compared between the two groups.Results There were no statistically significant differences between the two groups in terms of age,stone location,stone length or the incidence of surgical complications(all P＞0.05).The experimental group had a shorter stone localization time and a shorter surgical duration than the control group,with statistically significant differences(Z/t=-2.488,2.643,P=0.013,0.014).Conclusion The application of virtual endoscopy reconstruction technology in preoperative stone localization,surgical path planning,and intraoperative navigation can shorten stone localization time and surgical durations in ureteral flexible ureteroscopy,thereby improving surgical efficiency.
