This study aims to evaluate the effect of sling insertion angle on surgical outcomes and quality of life in women with stress urinary incontinence (SUI) undergoing single-incision midurethral sling surgery.
Women diagnosed with urodynamic stress urinary incontinence who underwent surgery using a single-incision sling system were included. Patients were categorized into two groups based on sling insertion angle: an acute-angle group (\<45°, resembling a retropubic trajectory) and a standard-angle group (approximately 45°, toward the obturator foramen).
The primary outcome was objective cure at 6 months, defined as a negative cough stress test without the need for additional anti-incontinence treatment. Secondary outcomes included objective cure at 1 and 3 months, postoperative voiding difficulty, persistent SUI symptoms, and quality of life assessed using the Incontinence Quality of Life (I-QOL) questionnaire.
This study provides clinical evidence on whether sling insertion angle influences early and mid-term outcomes following single-incision midurethral sling surgery.
