Abstract: Objective  To compare the clinical efficacy and complications of tension-free trans-obturator vaginal tape exact(TVT-E) and tension-free vaginal tape obturator(TVT-O) for female stress urinary incontinence(SUI). 
Methods  A retrospective analysis of 159 female SUI patients was performed. They were divided into TVT-E group(n=73) and TVT-O group(n=86) according to different treatment methods.Thesurgical indicators, clinical efficacy and complications were compared in the two groups. 
Results  The duration of operation was significantly longer in the TVT-E group than in the TVT-O group, and the difference was statistically significant(P＜0.05). There was no statistically significant difference in the amount of intraoperative blood loss, length of hospital stay, and postoperative residual urine volume between the two groups(P＞0.05). No significant difference was found in clinical efficacy and complication rate between the two groups(P＞0.05).  
Conclusion  The TVT-E group and the TVT-O group had similar surgical effects and complications, but the TVT-E group had a longer duration of operation and a higher risk of bladder perforation, as compared withTVT-O group. Patients who had recurrence after TVT-O can undergo further TVT-E. The TVT-E is simple and effective, and it is worthy of clinical promotion.
