Abstract:
【Objective】 To investigate the safety and efficacy of flexible vacuum aspiration ureteral access sheath in ureteroscopic lithotripsy in the treatment of renal and upper ureteral calculi. 【Methods】 Clinical data of 41 cases treated in our hospital were retrospectively analyzed, including 20 cases treated with flexible vacuum aspiration ureteral access sheath (experimental group), and 21 cases treated with traditional ureteral access sheath (control group). The stone-clearance rate, operation time, postoperative fever (T>37.5 ℃), length of hospital stay and hospitalization costs were compared between the two groups. 【Results】 All operations were successful. The experimental group had significantly shorter operation time than the control group [(54.0±19.8) min vs. (76.6±20.1) min, P<0.05], higher stone-clearance rate (90.0% vs. 61.9%, P<0.05), and lower incidence of postoperative fever (0 vs. 23.8% P<0.05). There were no significant differences in hospital stay and costs between the two groups (P>0.05). 【Conclusion】 Flexible vacuum aspiration ureteral access sheath in flexible ureteroscopic lithotripsy can shorten the operation time, improve stone-clearance rate and reduce incidence of postoperative fever, which is worth promoting.
