Brief summary

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

DEVICE1.2 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.

DEVICE1.0 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.

Intervention model description

This randomized, single-blind parallel-group study compares the surgical outcomes of two mesh widths (1.2 cm vs. 1.0 cm) used in transobturator tape (TOT) surgery for women with stress urinary incontinence (SUI).

Inclusion criteria

* Female patients aged 18 years or older * Clinical diagnosis of stress urinary incontinence (SUI), confirmed by: * Positive stress test (urine leakage on coughing with a comfortably full bladder) * Q-tip test showing urethral hypermobility (\>30 degrees) * Inadequate response to conservative therapy (e.g., pelvic floor muscle training, behavioral therapy) * Eligible for transobturator tape (TOT) surgery * Body mass index (BMI) less than 35 kg/m² * Able to provide informed consent and follow postoperative instructions

Exclusion criteria

* History of prior midurethral sling surgery * Mixed urinary incontinence or urge-dominant symptoms * Pelvic organ prolapse stage \> II according to the POP-Q system * Neurological disorders affecting bladder function (e.g., multiple sclerosis, spinal cord injury) * Active urinary tract infection or recurrent UTI (defined as ≥3 infections within the past 12 months) * Pregnant or planning to become pregnant within the next 12 months * Severe comorbid conditions (e.g., uncontrolled diabetes mellitus, active malignancy, pelvic radiotherapy) * Use of medications that significantly affect bladder function (e.g., anticholinergics, diuretics) * Inability or unwillingness to attend follow-up visits or comply with postoperative care plan

Design outcomes

Primary

MeasureTime frameDescription
Objective Cure Rate Based on Negative Stress Test6 months postoperativelyObjective cure will be defined as the absence of urinary leakage during a standardized cough stress test with a comfortably full bladder. The test will be performed by a blinded assessor at 6 months postoperatively.

Secondary

MeasureTime frameDescription
Change in ICIQ-SF Score6 months postoperativelyChange in total score on the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF), measured before surgery and at 6 months postoperatively. The ICIQ-SF ranges from 0 to 21, with higher scores indicating worse symptom severity and greater impact on quality of life.
Incidence of Mesh-Related Complications6 months postoperativelyIncidence of mesh-related complications including mesh erosion, bladder outlet obstruction, infection, and pain. Complications will be assessed by physical examination and patient-reported symptoms during follow-up visits.
Recurrence of Stress Urinary Incontinence6 months postoperativelyProportion of patients who present with recurrence of stress urinary incontinence, defined as a positive cough stress test or self-reported symptoms of urine leakage during physical activity. Time Frame: 6 months postoperatively
Patient Satisfaction Score6 months postoperativelyPatient satisfaction will be measured using a structured questionnaire that includes a 5-point Likert scale ranging from 1 (very dissatisfied) to 5 (very satisfied). Higher scores indicate greater satisfaction. Assessment will be conducted at the 6-month follow-up visit.
