Abstract：Objective:To investigate the effect of trans-urethral ureteroscopic laser lithotripsy combined with vacuum-assisted stone extraction sheath for renal pelvis calculi.Methods:This study enrolled 83 patients with renal pelvis or ureteropelvic junction calculi treated at Kaifeng People's Hospital from December 2020 to January 2024.Participants were randomly allocated via a random number table into:control group(n=38),received conventional trans-urethral ureteroscopic laser lithotripsy;observation group(n=45):underwent trans-urethral ureteroscopic laser lithotripsy combined with vacuum-assisted stone extraction sheath.The operation indicators,stone-free rate and recurrence rate,quality of life,and complications between the two groups were compared.Results:The operation duration and postoperative recovery hospital stay in the observation group were both shorter than those in the control group[operation duration:(71.48±8.37)min vs.(87.62±10.14)min;postoperative recovery hospital stay:(3.47±0.91)d vs.(4.23±1.16)d,and intraoperative blood loss of the observation group was less than that of the control group[(43.17±5.89)mL vs.(55.82±7.16)mL],and the difference was statistically significant(P＜0.001).The stone-free rate of the observation group was higher than that of the control group[100.00%(45/45)vs.89.47%(34/38)],and the difference was statistically significant(P＜0.05).There was no significant difference in the recurrence between the two groups[2.22%(1/45)vs.7.89%(3/38)](P＞0.05).After operation,the scores of bodily pain,general health,mental health and quality of life in the observation group were all higher than those in the control group,and the difference was statistically significant(P＜0.001).Lower complication rate in the observation group[8.89%(4/45)vs.31.58%(12/38 cases)](P＜0.01).Conclusions:Trans-urethral ureteroscopic laser lithotripsy combined with vacuum-assisted stone extraction sheath for renal pelvis calculi demonstrates significant clinical effect for renal pelvis calculi,effectively improving stone-free rates while reducing postoperative complications,with an acceptable safety profile.
