Abstract Objective: To study the safety and efficacy of both tensionfree vaginal tape (TVT) and secure tension-free vaginal tape (TVT secur) in treatment of female stress urinary incontinence. Patients and Methods: Sixty female patients diagnosed as stress urinary incontinence were evaluated in the urogynecology clinic of the Benha Faculty of Medicine. All patients completed the impact of Incontinence on Quality of Life Questionnaire. They were randomly divided into 2 equal groups: group I (n = 30) underwent TVT procedure and group II (n = 30) underwent TVT secur procedure. The 2 techniques were compared regarding operative time, intraoperative bleeding, duration of catheterization, intra- and post-operative complications and hospital stay. All patients were followed up for 9 months and subjected to evaluation by history, examination, and urodynamics pre- and post-operatively. Results: Operative time and intra-operative morbidity were significantly lower in the TVT secur group than in the TVT group. No significant difference could be detected regarding catheterization period and success rate. The cure rate was 90.1% in group I and 93.4% in group II and this difference was statistically insignificant. Patients with a Valsalva leak point pressure lower than 60 cm H2O had poor outcome in both groups. Conclusion: TVT secur could be considered as a safe, easy and effective alternative to TVT with less morbidity.
