About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Female patients aged 18 years or older

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)

Disqualifiers

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)

Trial design

Design model

Parallel

Treatments tested in this trial

  • 1.2 cm Mesh TOT

    Device

    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.

  • 1.0 cm Mesh TOT

    Device

    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.

Treatment groups

106 Participants
are divided into 2 treatment groups
Group A: 1.2 cm Mesh (Intervention Group)Experimental treatment 1 intervention
Group B: 1.0 cm Mesh (Control Group)Active comparator 1 intervention

Trial outcomes

Primary outcomes

1

Objective Cure Rate Based on Negative Stress Test

Objective 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.

Time frame
6 months postoperatively

Secondary outcomes

1

Change in ICIQ-SF Score

Change 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.

Time frame
6 months postoperatively
2

Incidence of Mesh-Related Complications

Incidence 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.

Time frame
6 months postoperatively
3

Recurrence of Stress Urinary Incontinence

Proportion 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

Time frame
6 months postoperatively
4

Patient Satisfaction Score

Patient 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.

Time frame
6 months postoperatively
