摘要：Objective: The objective of this study was to report which preoperative and intraoperative factors influence the success of the tension-free vaginal tape procedure for stress urinary incontinence. study design: This was a pros.e.tive cohort study of 809 patients. In 28 teaching hospitals and 13 local hospitals, 54 gynecologists and urologists performed the tension-free vaginal tape procedure. Results: Before treatment and 2 years postoperatively, the following question from the Urogenital Distress Inventory for stress urinary incontinence was selected to define success or failure: “Do you experience urinary leakage during physical activity, coughing, or s.e.zing?”secondary outcome measurement was the outcome of the doctor’s question,“Do you leak during physical activity, coughing, or s.e.zing?”as.e. at the 2-year follow-up. Response rate was 78.7%. The success rate was significant higher in all analyses when the surgeons had performed more than 20 tension-free vaginal tape procedures (P = .003; beta = 1.918 [95%confidence interval 1.24-2.97]). General anesthesia had a negative effect on the success of the tension-free vaginal tape (P = .032; beta = 2.21 [95%confidence interval 1.07-4.55]). Conclusions:Inexperience of the surgeon with the tension-free vaginal tape procedure and general anesthesia had a negative effect on the result. We believe that the tension-free vaginal tape should be performed only by experienced surgeons.
