ESWL与URSL治疗输尿管下段结石的疗效比较

Comparison of ESWL and URSL in the treatment of distal ureteral calculi

目的比较体外冲击波碎石术(ESWL)与输尿管镜气压弹道碎石术(URSL)治疗输尿管下段结石的疗效和安全性。方法总结ESWL和URSL治疗输尿管下段结石200例的临床资料,其中ESWL组105例,URSL组95例。结果 ESWL组的单次碎石成功率为61.9%(65/105),URSL组为94.7%(90/95);ESWL组术后4周的结石排净率为67.6%(71/105),URSL组为97.8%(88/90);比较2组疗效差异有显著性(P<0.05)。结论 URSL治疗输尿管下段结石疗效明显优于ESWL。

Objective To compare the therapeutic effect and safety of extracorporeal shock wave lithotripsy （ESWL） and ure- teroscopic pneumatic lithotripsy（ URSL） in the treatment of distal ureteral calculi. Methods Clinical data of 200 cases （ 105 with ESWL,95 with URSL ） for the treatment of distal ureteral calculi were analyzed. Results In the ESWL group, the single success rate for the lithotripsy was 61.9 % （ 65/105 ） while the rate was 94.7% （ 90/95 ） in the URSL group. The calculus clearance rate in the ESWL group was 67.6% （ 71/105 ）four weeks after the operation, meanwhile the rate was 97.8% （88/ 90） in the URSL group. The difference had great significance（ P 〈 0.05 ）. Conclusion For the treatment of distal ureteral cal- culi, URSL has a better therapeutic effect than ESWL.
