title: [Risk factors for failure after transobturator vaginal tape for urinary incontinence].
abstract: OBJECTIVE
  To identify risk factors leading to treatment failure in a sample of 302 women with stress urinary incontinence (SUI) treated by transobturator vaginal tape (TOT) with a medium follow-up of 4 years (range 1-6).
  
  
  METHODS
  A population based cohort study with prospectively data from 302 women, aged 41-81 years underwent TOT between April 2003-November 2010. Data were collected by validated questionnaire on urinary incontinence, the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF), and clinical data-records. Continence was achieved in 262 (Group A) and 40 continued with incontinence (Group B). We investigated the relationship between age, SUI evolution time, type and number of childbirths (eutocic, dystocic, nulliparous, multiparous status) and medical and/or surgical backgrounds. The ICIQ-SF questionnaire was used to describe whether the surgery outcomes were successful or not.
  
  
  RESULTS
  Group A were younger (p=0.0001), had less SUI evolution time (p=0.017); more eutocic childbirths (p=0.000018). Group B had more dystocic childbirth (p=0.022), previous tension free vaginal tape (TVT) or TOT (p=0.03.), antidepressant-anxiolytic drugs (p=0.003), antihypertensive drugs (p=0.0005), type 1 diabetes (p=0.02), arterial hypertension (p=0.0007), respiratory diseases (p=0.025). Differences were not found with regard to nulliparous (p=0.701), multiparous status (p=0.42), obesity (p=0.18), intestinal disorders (p=0.59), oophorectomy (p=0.19), caesarean (p=0.17), prolapse surgery (p=0.29), hysterectomy (p=0.57), allergies (p=0.48), arthritis (p=0.22), arthrosis (p=0.44), depression (p=0.74), type 2 diabetes (p=0.44), smoking patterns (p=0.28), fibromyalgia (p=0.47).
  
  
  CONCLUSIONS
  Elderly women, with long evolution SUI, dystocic delivery, previous TVT or TOT appear as independent risk factors associated to TOT failure. These factors may make the indication of another surgical approach recommendable.
