球囊扩张术与钬激光内切术治疗继发性输尿管狭窄的对比研究

Comparison of balloon dilation and YAG laser endouretertomy in treatment of secondary ureteric stricture

目的随访对比分析球囊扩张术与钬激光内切术治疗继发性输尿管狭窄的临床效果。方法将32例继发性输尿管狭窄患者随机分为球囊扩张组和钬激光内切组,每组16例,分别进行上述两种手术方式。术后第3、6、12和24个月分别进行随访并比较两组患者术后输尿管狭窄的治疗效果。结果在第3、6和12个月两组临床效果随访结果显示差异均无统计学意义(P>0.05),总体有效率方面差异均无统计学意义(P>0.05)。在第24个月时,两组临床效果差异有统计学意义(P<0.05),总体有效率差异有统计学意义(P<0.05)。结论球囊扩张术和钬激光内切术治疗继发性输尿管狭窄的近期临床效果相当,钬激光内切术治疗继发性输尿管狭窄的中期临床疗效优于球囊扩张术。

Objective To compare the effcacy of balloon dilation and YAG laser endouretertomy in treatment of secondary ureteric stricture . Methods 32 patients with secondary ureteral stricture were randomly divided into balloon dilatation group and holmium laser cut group, 16 cases in each, respectively. The two kinds of treatment efficacy was compared after two years postoperative follow-up. Results The clinical results of the two groups showed no statistical differences at the third, sixth and twelfth month follow-up （P 〉 0.05）, and there were no statistical differences in the overall effective rates （P 〉 0.05）. The clinical results of the two groups showed no statistical difference at the twenty-fourth month follow-up （P 〈 0.05）, and the overall effective rates had statistical difference （P 〈 0.05）. Conclusions Balloon dilation and YAG laser endouretertomy in treatment of secondary ureteral stricture have the same short-term clinical effects. But the middle-term effcacy of YAG laser endouretertomy is superior to that of balloon dilation.
