Abstract：Objective: To compare the effect of vacuum suction ureteral access sheath and normal ureteral access sheath in flexible ureterorenoscope lithotripsy. Methods: Compare clinical data of patients underwent flexible ureterorenoscope lithotripsy between 2017-08 and 2019-12. 100 patients were randomly allocated in each group, respectively. Intraoperative situation, inflammatory indicators and stone residual rate were observed and compared. Results: Vacuum suction sheath group showed advantages over normal sheath group in most observed aspects with statistical significance.Intraoperative situation： operation time （44.91±16.54 vs.54.20±19.78 min）, ureter injury （0 cases vs.2 cases）; Inflammatory indicators： instant WBC count （10.3±4.2×109/L vs.12.8±5.0×109/L）, instant PCT （1.64±1.22μg/L vs.2.43±3.33 μg/L）, WBC fallbackduration （1.23±1.07 days vs.1.72±1.14 days）, PCT fallback duration （1.26±0.96 days vs.1.68±1.11 days）, peak temperature （37.19±0.95℃ vs.37.78±1.17℃）, qSOFA≥2 （2/9 cases）; Stone residual rate1 day （13% vs.27%）, stone residual rate 30days （3% vs.9%）. Septic shock did notshow statistical significance, but both trend and case number revealed vacuum suction sheath has the advantage. Conclusion: Vacuum suction ureteral access sheath has great advantages in direct sheath insertion, vacuum suction of irrigation liquid and stone fragments, low ureter injury rate and low stone residual rate.
