Comparison of the Effectiveness and Safety of Bendable Negative Pressure Suction Sheaths and Common Sheaths in Ureteral Flexible Scope for the Treatment of Renal Calculi
Objective To investigate the effectiveness and safety of the application of bendable negative pressure suction sheath versus common sheath in the treatment of renal calculi by ureteral flexible scope.Methods A total of 200 patients with kidney stones admitted to the Department of Urology,923 Hospital of the Chinese People's Liberation Army Joint Logistic Support Force from July 2019 to December 2023 were selected as the study objects,and they were divided into control group(100 cases)and observation group(100 cases)ac-cording to 1:1 grouping method.The two groups were treated with ureteroscope.The control group was treated with conventional sheath and the observation group was treated with flexible negative pressure suction sheath.The intraoperative condition,postoperative infection index,renal function and postoperative stone removal rate were compared between the two groups.Results Intraoperative blood loss(1.78±0.35)mL and operative time(255.36±10.15)min in the observation group were better than those in the control group(3.61±0.57)mL,(323.19±9.28)min,and the differences were statistically significant(t=27.359,49.320,both P<0.05).The inci-dence of ureteral injury caused by sheath implantation in the observation group was 2.00%,which was lower than that in the control group(9.00%),and the difference was statistically significant(χ2=4.713,P<0.05).There was no significant difference between two groups of the levels of blood white blood cells,neutrophil percentage,hypersensitive C-reactive protein,Neutropil Gelatinase-Associated Lipocalin(NGAL),Creatinine(Cr)and Cys-tatin C(CysC)(all P>0.05).The percentage of white blood cells,neutrophils,hypersensitive C-reactive protein,NGAL,Cr and CysC,and postoperative fever in the observation group were lower than those in the control group,and the differences were statistically significant(all P<0.05).The immediate stone removal rate in the ob-servation group was 95.00%,higher than that in the control group(79.00%),and the difference was statistically significant(P<0.05).Conclusion Compared with the common sheath,the bendable negative pressure suction sheath has a better suction effect in the process of ureteral flexible scope for treating kidney stones,which makes the surgical field clearer,effectively reduces the incidence of ureteral injury and postoperative infection caused by sheath placement,and improves the stone clearance rate.
