Resumo

The study presents an analysis of the experience of treatment of urinary incontinence in women using free synthetic suburethral sling. Between 2001 and 2008, 1081 patients underwent surgery. Of these, 841 (77,8%) suffered from stress urinary incontinence, 202 (18,62%) suffered from the mixed form of urinary incontinence with a predominance of the stress component, and 38 (3,52%) had recurrent urinary incontinence. Group 1 included patients with stress urinary incontinence who underwent surgery using suburethral synthetic sling with retropubic access (TVT operation); Group 2 included patients, who underwent surgery using suburethral sling implanted with transobturator access (TVT-O operation). Group 3 consisted of patients with mixed urinary incontinence, who underwent TVT-O operation. Retropubic suburethral TVT sling was implanted in 273 (25,25%) patients, transobturator TVT-O sling - in 740 (68,45%) patients, and other synthetic suburethral slings - in 68 (6,3%) patients. The average follow-up period was 50.1, 31.1 and 32,6 months in each group, respectively. Cough test was used for the objective evaluation of the effectiveness, and visual analogue scale - for the subjective evaluation of effectiveness. In the TVT group, the negative cough test in the postoperative period remained at 85,58% of the patients, and in in TVT-O group - in 84,36% of patients. Analysis of the frequency of intraoperative complications showed that the probability of occurrence of complications was not associated with age, body mass index and obstetric history of patients. It was noted that the perforation of the bladder and pelvic hematoma were more likely to occur when using the retropubic access. Transobturator access is associated with a higher risk of injury of the lateral vaginal fornix, although bladder injury is not ruled out. Objective and subjective indicators of efficacy of treatment of mixed form ofurinary incontinence were 86.15 and 87.69%, respectively. The study suggests that the operations using suburethral TVT and TVT-O slings are safe and effective methods of treatment of stress urinary incontinence in women.
