Abstract:
Objective:To compare the safety and effectiveness of disposable and reusable flexible electronic ureteroscopes in the treatment of upper urinary tract stones in elderly patients.Methods:A retrospective analysis was made on clinical data of elderly patients with unilateral upper urinary tract calculi receiving flexible ureteroscopic lithotripsy at Beijing Hospital between March 2020 and November 2022.According to the type of the flexible ureteroscope used, patients who met the requirements for inclusion were divided into a single-use flexible ureteroscope group and a reusable flexible ureteroscope group.The stone-free rate, the operative time, the length of postoperative hospitalization and the incidence of postoperative systemic inflammatory response syndrome(SIRS)were compared between the two groups.Results:A total of 225 eligible participants were enrolled from Beijing Hospital, of whom 107 in the single-use flexible ureteroscope group and 118 in the reusable flexible ureteroscope group underwent evaluation.The operative time[60(40, 97)min vs.75(60, 110)min, Z=-2.947, P=0.003]and the length of postoperative hospitalization[1(1, 2)days vs.1(1, 2)days, Z=-2.554, P=0.011]of the single-use flexible ureteroscope group were shorter than those of the reusable flexible ureteroscope group.There were no statistically significant differences in the lithotripsy success rate[89/107(83.2%) vs.92/118(78.0%), χ2=0.969, P=0.325]and the incidence of postoperative SIRS[8/107(7.5%) vs.14/118(11.9%), χ2=1.225, P=0.268]. Conclusions:There is no significant difference in the lithotripsy success rate and postoperative SIRS rate between single-use digital flexible ureteroscopes and reusable flexible digital ureteroscopes for lithotripsy of upper ureteral stones in elderly patients, while the operative time and the length of postoperative hospitalization of using single-use flexible ureteroscopes are shorter than those of using reusable flexible ureteroscopes.Single-use digital flexible ureteroscopes have satisfactory safety and effectiveness for the treatment of upper urinary tract calculi in elderly patients.
