Effect of ureteral occlusion apparatus for reverse blocking in percutaneous nephrolithotomy
Objective:To investigate the clinical value of ureteral occlusion apparatus for reverse blocking in percutaneous nephrolithotomy(PCNL).Methods:Sixty patients with renal calculi hospi-talized in the Department of Urology,the First Affiliated Hospital of Bengbu Medical College from Sep-tember 2019 to September 2022 were selected.Among them,30 patients who used ureteral occlusion apparatus for reverse blocking during PCNL were used as the observation group,and 30 patients who were treated with conventional PCNL were used as the control group.The amount of bleeding,opera-tion time,stone clearance rate,downward rate and incidence of related complications were compared between the two groups,and the efficacy was evaluated comprehensively by excellent,good and poor grades.Results:There was no significant difference in intraoperative bleeding volume between the obser-vation group[(55.83±2.07)mL]and the control group[(55.73±2.02)mL](P>0.05).The opera-tion time and stone clearance rate of the observation group were 48.50(47.00-50.00)min and 96.67%,which were higher than 46.00(45.00-48.00)min and 80.00%of the control group(P<0.05).The stone moving rate of the observation group was 3.33%,and the incidence of related complications was 3.33%,which were lower than 23.33%and 23.33%of the control group(P<0.05).Conclusion:The application of ureteral occlusion apparatus in PCNL for reverse blocking can effectively promote stone clearance and avoid adverse events such as stone downward movement.
