Abstract Objective To explore the efficacy of single versus double J ureteral stent placement in the treatment of recurrent benign ureteral stricture. Methods From January 2012 to December 2016, 26 patients with recurrent benign ureteral stricture in the Department of Urology, Liuzhou General Hospital, Guangxi Zhuang Autonomous Region were selected as the research objects and divided into the single J ureteral stent group and the double J ureteral stent group by random number table. The clinical efficacy was compared between the two groups after stent placement. Before and after 3 months of stent placement, the levels of serum creatinine and hydronephrosis were compared between the two groups. Results After stent placement, the total effective rate in double J ureteral stent group was higher than that in single J ureteral stent group, but with no statistically significant difference (P ＞ 0.05). Before and after stent placement, there were no statistically significant differences in the levels of serum creatinine between the two groups and within groups (P ＞ 0.05). In the single J ureteral stent group, there was no statistically significant difference in hydronephrosis before and after stent placement (P ＞ 0.05), but after stent placement, that in the double J ureteral stent group was lower than that of before stent placement and that in the single J ureteral stents group, with statistically significant differences (P ＜ 0.05). Conclusion The efficacy and the drainage of double J ureteral stent placement in the treatment of recurrent benign ureteral stricture are better than those of single J ureteral stent placement. However, the long-term effects and mechanisms need to be further studied and verified by large samples.
