Overview
This study is a single-blind, randomized controlled trial evaluating whether changing the width of the surgical tape (mesh) used in transobturator tape (TOT) surgery improves treatment results in women with stress urinary incontinence (SUI). Two mesh widths are being compared: a 1.2 cm mesh (new method) and a 1.0 cm mesh (standard method). The main goal is to find out if the wider mesh leads to better urinary control and fewer complications. Participants will be followed for one year to measure cure rates, symptom improvement, and satisfaction.
Detailed description
This is a prospective, single-blind, randomized controlled trial evaluating the effect of mesh width on surgical outcomes in transobturator tape (TOT) procedures for women with stress urinary incontinence (SUI). A total of 106 participants will be randomized using a computer-generated allocation into two groups receiving either a 1.2 cm mesh (intervention group) or a 1.0 cm mesh (standard procedure).
The procedures will be conducted by a single experienced surgeon using a monofilament polypropylene mesh to ensure standardization. Surgical technique, anesthesia protocols, and perioperative management will be identical in both groups.
Primary outcome is objective cure, defined as negative stress test at 6 months. Secondary outcomes include symptom improvement (ICIQ-SF), mesh-related complications (erosion, infection, retention), and patient satisfaction assessed via structured Likert survey.
Follow-up visits are scheduled at 1 week, 1 month, and 1 year. Postoperative assessments will be conducted by a blinded evaluator. The study aims to evaluate whether wider mesh width provides superior anatomical support and reduces complication rates in comparison to standard mesh.
Interventions
- Device 1.2 cm Mesh TOT
Patients in this group will undergo transobturator tape (TOT) surgery using a 1.2 cm monofilament polypropylene mesh. The modified mesh width is being evaluated for its effect on surgical success, symptom improvement, and postoperative complications. - Device 1.0 cm Mesh TOT
Patients in this group will undergo transobturator tape (TOT) surgery using a 1.0 cm monofilament polypropylene mesh, which is the standard procedure. This group serves as a comparator to assess the impact of the modified mesh width.
Primary outcome measures
- Objective Cure Rate Based on Negative Stress Test [Time frame: 6 months postoperatively]
Secondary outcome measures (4)
- Change in ICIQ-SF Score [Time frame: 6 months postoperatively]
- Incidence of Mesh-Related Complications [Time frame: 6 months postoperatively]
- Recurrence of Stress Urinary Incontinence [Time frame: 6 months postoperatively]
- Patient Satisfaction Score [Time frame: 6 months postoperatively]
