输尿管镜术中使用3Fr输尿管导管与斑马导丝引导入镜的临床对比OA

Objective To compare the clinical effects of 3Fr ureteral catheter and zebra guidewire in guiding scope insertion duringureteroscopy.Methods A total of 161 patients who were scheduled to undergo ureteroscopy in the hospital from January 2022 to July 2025 were enrolled in this study.They were randomly divided into the 3Fr ureteral catheter group(n=81)and the zebra guidewire group(n=80)by the envelope method.The operation time of the two groups was compared,as well as the differences in C-reactive protein(CRP),urine protein/creatinine ratio(UPCR)before and after the operation and the occurrence of complications.Results The operation time of the 3Fr ureteral catheter group was signifi-cantly longer than that of the zebra guidewire group(P<0.05).In all subgroups based on stone size(≤1.5 cm or>1.5 cm)and stone location(upper or mid-lower segment),the 3Fr catheter group also exhibited significantly longer operative times than the zebra guidewire group(P<0.05).Postoperatively,both groups showed elevated CRP and UPCR levels,with the 3Fr catheter group significantly higher than the zebra guidewire group,and this difference remained significant across all subgroups(P<0.05).The incidence of ureteral injury in the Fr ureteral catheter group was significantly lower than that in the Zebra guidewire group(4.94％vs.15.00％),while the incidence of stones returning to the kidney was significantly higher in the Fr ureteral catheter group than in the Zebra guidewire group(11.11％vs.2.50％;P<0.05).The total incidence of complications between the two groups was not significantly different(P>0.05).Conclusion 3Fr ureteral catheter has more advantages in reducing ureteral mucosal injury,while zebra guidewire performs better in shortening operation time,reducing the risk of stone displacement,and alle-viating postoperative stress response.It is recommended that the appropriate guidance method be chosen based on the patient's condition and surgical requirements.
