Abstract:Objective?To compare the efficacy 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 efficacy of YAG laser endouretertomy is superior to that of balloon dilation.
