ABSTRACT
【Objective】 To analyze the causes of the failure of previous operations in female patients with stress urinary incontinence (SUI), and to evaluate the efficacy and safety of modified transobturator outside-in tape (TOT). 【Methods】 A total of 42 female SUI patients who had failed in previous anti-incontinence surgery during Aug.2016 and Jul.2022 were enrolled. The causes of failure were analyzed. All patients were treated with modified TOT, and the operation time, estimated blood loss, duration of catheterization, symptom improvement and complications were observed. The outcomes were evaluated with the International Consultation on Incontinence Questionnaire Short Form (ICI-Q-SF), pad test and urodynamic study. 【Results】 All operations were technically successful. The average operation time was (32.4±18.6) min, and estimated blood loss was (54.2±34.5) mL. There were no obvious complications. After operation, the ICI-Q-SF score significantly decreased (P0.05). The overall effective rate was 88.1%. 【Conclusion】 Modified TOT can be used for the treatment of patients with failed anti-SUI surgery, which is simple and easy to perform, with a low complication rate and satisfactory postoperative results.
