Midterm postoperative results of mid‐urethral slings. Role of ultrasound in explaining surgical failures

Introduction Surgical treatment for stress urinary incontinence (SUI) with mid‐urethral sling (MUS) is considered to have a high success rate. However, between 5% and 20% of MUS fail, with inadequate surgical implantation being a possible cause of SUI persistence or recurrence. Misplacement of a MUS can be determined by pelvic floor ultrasound (PF‐US). The aim of this study was to investigate the role of PF‐US in patients with persistent or recurrent urinary incontinence (UI) symptoms after MUS surgery for SUI with a midterm follow‐up. Materials and Methods A historical cohort study including women undergoing MUS surgery for SUI between 2013 and 2015 was designed. The primary outcome was to correlate the sonographic parameters of MUS with SUI cure (negative International Continence Society‐Uniform Cough Stress Test, Incontinence Questionnaire‐Short Form
