ABSTRACT
Summary Introduction: Digital palpation and manometry are methods that can provide information regarding maximum voluntary contraction (MVC) and endurance of the pelvic floor muscles (PFM), and a strong correlation between these variables can be expected. Objective: To investigate the correlation between MVC and endurance, measured by digital palpation and manometry. Method: Forty-two women, with mean age of 58.1 years (±10.2), and predominant symptoms of stress urinary incontinence (SUI), were included. Examination was firstly conducted by digital palpation and subsequently using a Peritron manometer. MVC was measured using a 0-5 score, based on the Oxford Grading Scale. Endurance was assessed based on the PERFECT scheme. Results: We found a significant positive correlation between the MVC measured by digital palpation and the peak manometric pressure (r=0.579, p<0.001), and between the measurements of the endurance by Peritron manometer and the PERFECT assessment scheme (r=0.559, P<0.001). Conclusion: Our results revealed a positive and significant correlation between the capacity and maintenance of PFM contraction using digital and manometer evaluations in women with predominant symptoms of SUI.
Resumo Introdução: a palpação digital e a manometria são métodos capazes de fornecer informações sobre contração voluntária máxima (CVM) e endurance da musculatura do assoalho pélvico (MAP), e pode-se esperar uma forte correlação entre essas variáveis. Objetivo: investigar a correlação entre CVM e endurance, avaliados por palpação digital e manometria. Método: incluíram-se 42 mulheres, com idade média de 58,1 anos (±10,2) e sintomas predominantes de incontinência urinária de esforço (IUE). Realizou-se primeiramente o exame digital, seguido pela manometria (Peritron®). Mensuraram-se a CVM de acordo com a escala de Oxford (0-5 pontos) e o endurance pelo esquema PERFECT. Resultados: encontrou-se correlação positiva entre CVM mensurada por palpação digital e pressão manométrica de pico (r=0,579; p<0,001), e entre as medições do endurance avaliado pelo Peritron e o esquema PERFECT (r=0,559; p<0,001). Conclusão: os resultados revelaram correlação positiva e significativa entre a capacidade e a manutenção de contração dos MAP por meio das avaliações digital e manométrica em mulheres com IUE.

OBJECTIVE: To assess the prevalence of urinary incontinence and associated vaginal squeeze pressure in primiparous women with and without previous gestational diabetes mellitus two years post-cesarean delivery. METHODS: Primiparous women who delivered by cesarean two years previously were interviewed about the delivery and the occurrence of incontinence. Incontinence was reported by the women and vaginal pressure evaluated by a Perina perineometer. Sixty-three women with gestational diabetes and 98 women without the disease were screened for incontinence and vaginal pressure. Multiple logistic regression models were used to evaluate the independent effects of gestational diabetes. RESULTS: The prevalence of gestational incontinence was higher among women with gestational diabetes during their pregnancies (50.8 percent vs. 31.6 percent) and two years after a cesarean (44.8 percent vs. 18.4 percent). Decreased vaginal pressure was also significantly higher among women with gestational diabetes (53.9 percent vs. 37.8 percent). Maternal weight gain and newborn weight were risk factors for decreased vaginal pressure. Maternal age, gestational incontinence and decreased vaginal pressure were risk factors for incontinence two years after a cesarean. In a multivariate logistic model, gestational diabetes was an independent risk factor for gestational incontinence. CONCLUSIONS: The prevalence of incontinence and decreased vaginal pressure two years post-cesarean were elevated among women with gestational diabetes compared to women who were normoglycemic during pregnancy. We confirmed an association between gestational diabetes mellitus and a subsequent decrease of vaginal pressure two years post-cesarean. These results may warrant more comprehensive prospective and translational studies.
