GAN Yunhui,WANG Xuhong,SHI Wenying. Curative effect of disposable electronic ureteroscope in the treatment of lower calyceal stones[J]. JOURNAL OF WEZHOU MEDICAL UNIVERSITY, 2022, 52(10): 829-832.
Abstract：Objective: To investigate the efficacy of a home-made disposable digital flexible ureteroscope compared with fiberoptic flexible ureteroscope in the treatment of lower calyceal stones ≤2 cm. Methods: A total of 80 patients with stones ≤2 cm in the lower calyx of the kidney from Wuxing District People’s Hospital in Huzhou from April 2020 to June 2021 were retrospectively analyzed. They were divided into disposable digital flexible ureteroscope group (DDFU group, 38 patients) and fiberoptic flexible ureteroscope group (FFU group, 42 patients). The preoperative, intraoperative, and postoperative data as well as the 3-month postoperative followup data were compared between the 2 groups, and the performance indexes of the 2 ureteroscopes were also compared. Results: There were no differences between the 2 groups in intraoperative stone seeking rate, duration of hospital stay, postoperative fever (P>0.05), but statistical differences were observed in operative time,occurrence of postoperative hemorrhage/hematoma, and stone clearance (P<0.05). Conclusion: The operating performance of disposable digital flexible scopes is better than that of fiberoptic flexible ureteroscopes. In the treatment of lower calyceal stones, the disposable digital flexible ureteroscope is safer and more effective with shorter procedure time, less bleeding and higher stone clearance rate.
