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.
