PURPOSE: to translate, culturally adapt and validate the questionnaire "International Consultation on Incontinence Questionnaire Overactive Bladder" (ICIQ-OAB) for the Portuguese Language. METHODS: two Brazilian translators acquainted with the objectives of this research translated the ICIQ-OAB into Portuguese and both translations were back-translated by two other native English speaking translators. The differences between the versions were brought to agreement and pre-tested in a pilot study. The final version of the ICIQ-OAB was applied together with the previously translated and tested version of the International Consultation on Incontinence Questionnaire -Short Form (ICIQ-SF) in 142 male and female patients with irritative urinary symptoms. For the validation of the ICIQ-OAB the following psychometric features were evaluated: reliability (internal consistency and test-retest) and validity of the survey. The retest was performed four weeks after the first interview. RESULTS: the reliability of the instrument was demonstrated through the Cronbach α Coefficient, with a general result of 0.7. The test-retest corroborated the stability of the instrument through the intraclass correlation coefficient and presented a result of 0.91 and 0.95 when compared to both the ICIQ-OAB and ICIQ-SF, respectively. When the instruments were compared by the Pearson correlation coefficient the result was 0.7 (p=0.0001), that confirms the validity of the study criterion. The concurrent validity was evaluated by

(2), persisting after delivery in 6% to 29% of women (3). Estimating the post-partum prevalence of urinary incontinence is complex because the prevalence may depend upon the number of previous births, type of delivery, and history of previous inVol. 38 (2): 267-276; March -April, 2012 Introduction and Objectives: The increase of the intensity of urinary symptoms in late pregnancy and postpartum has been well documented by several authors, but their causes remain uncertain, partly because of its probable multifactor origin. There are also controversies whether the etiology of lower urinary tract symptoms during pregnancy is the same as postpartum and whether the method of delivery could infl uence the risk of onset of urinary symptoms. This study aimed to evaluate the urinary symptoms triggered during pregnancy and its evolution in the late puerperium, correlating them with the delivery method. Materials and Methods: A longitudinal study was conducted, which included 75 primigravidae women, classifi ed according to method of delivery as: (VD) vaginal delivery with right mediolateral episiotomy (n = 28); (CS) elective caesarean section (n = 26); and (EC) emergency caesarean section (n = 21). Urinary symptoms were assessed in the last trimester of pregnancy and at 45 days (± 10) of puerperium with validated versions for Portuguese language of the following questionnaires: International Consultation on Incontinence Questionnaire -Urinary Incontinence Short Form (ICIQ-UI SF) and the International Consultation on Incontinence Questionnaire Overactive Bladder (ICIQ-OAB). Results: It was observed that frequency, urgency, nocturia and urge incontinence, triggered during pregnancy, decreased signifi cantly in the postpartum period, regardless of the delivery method (p = 0.0001). However, symptoms related to urinary loss due to stress persisted after vaginal delivery (p = 0.0001). Conclusions: Urgency, frequency and nocturia triggered during pregnancy tend to disappear in the late postpartum period, regardless of the delivery method, but the symptoms related to urinary loss due to stress tend to persist in late postpartum period after vaginal delivery.
