Abstract in Portuguese
INTRODUÇÃO: A disfunção do trato urinário inferior (DTUI) pode decorrer de contrações vesicais durante a fase de enchimento (hiperatividade do detrusor) ou a falta de coordenação entre a contração vesical e o relaxamento dos músculos do assoalho pélvico durante o esvaziamento vesical (disfunção miccional). Várias publicações sugerem benefícios do uso de biofeedback eletromiográfico (EMG) e eletroestimulação transcutânea parassacral (ENTP) no tratamento destas condições. Contudo faltam estudos controlados comparando estas duas formas de tratamento. OBJETIVO: Comparar a eficácia das técnicas de biofeedback EMG e ENTP em crianças com DTUI. MÉTODOS: Estudo prospectivo e randomizado com 64 crianças, sendo 43 meninas e 21 meninos com idade média 9,39 anos. As crianças foram divididas em dois grupos de tratamento: grupo biofeedback (GB) e grupo de ENTP (GE). Os critérios para avaliar a eficácia do tratamento foram a taxa de resolução dos sintomas noturnos e diurnos, comprovados por diário miccional, urofluxometria, questionários (DVSS - Dysfunction voiding symptoms score), avaliação da qualidade de vida (QV), melhora da constipação e do número de episódios de infecção do trato urinário (ITU).RESULTADOS: No GB 54,9% das crianças tiveram resposta completa e no GE 60,6% em relação a melhora diurna (p=0,483) e 29,6% e 25% em relação a melhora noturna respectivamente (p=0,461). Em relação ao diário miccional, urofluxometria e DVSS, ambos os grupos tiveram melhora estatisticamente significante (p=0,001), porém a QV não teve diferença entre os grupos (p=0,959 e p=0,065). Na avaliação da constipação, houve decréscimo no GB de 61,3% para 19,4% (p=0,002) e no GE de 33,3% para 6,2% (p=0,013). Nenhuma criança apresentou ITU após o término do tratamento (p < 001). CONCLUSÃO: O biofeedback EMG e a ENTP são efetivos para o tratamento de DTUI.Esta eficácia se traduz por melhora dos sintomas diurnos e noturnos bem como na avaliação feita por questionário e urofluxometria. Ambas as técnicas se mostrarm eficazes, embora o biofeedback tenha requerido um menor número de sessões

Abstract in English
INTRODUCTION: The lower urinary tract dysfunction (LUTD) may be due to bladder contractions during the filling phase (detrusor overactivity) or the lack of coordination between bladder contraction and relaxation of the pelvic floor muscles during bladder emptying (voiding dysfunction ). Several publications have suggested benefits of using electromyographic biofeedback (EMG) and parasacral transcutaneous electrical nerve stimulation (TENS) in treating these conditions. However there is a lack of controlled studies comparing these two forms of treatment. OBJECTIVE: To compare the effectiveness of EMG biofeedback and parasacral TENS techniques in children with DTUI. METHODS: A prospective and randomized study with 64 children, 43 girls and 21 boys, mean age 9.39 years. The children were divided into two treatment groups: biofeedback group and parasacral TENS. The criteria for assessing the effectiveness of techniques were the rate of resolution of daytime and nighttime symptoms, improvements in voiding diary, uroflowmetry and questionnaires. (DVSS - Dysfunction voiding symptoms score). We also acessed changes in quality of life (QOL) constipation and number of episodes of lower urinary tract infection (UTI). RESULTS: GB 54.9% of children had complete response in EMG biofeedback group and 60.6% in those treated by parasacral TENS in daytime symptoms (p = 0.483) and 29.6% and 25% in night time respectively (p = 0.461). Regarding the voiding diary, uroflowmetry and DVSS, both groups had statistically significant improvement (p = 0.001), but the QOL showed no difference between groups (p = 0.959 and p = 0.065). In the evaluation of constipation, there was a decrease in EMG biofeedback group 61.3% to 19.4% (p = 0.002) and in parasacral TENS group 33.3% to 6.2% (p = 0.013). No child had UTI after the end of treatment (p <.001). CONCLUSION: EMG biofeedback and the parasacral TENS are effective for treating DTUI. This efficiency translates into improved daytime and nighttime symptoms as well as in the evaluation made by questionnaire and uroflowmetry. Both techniques showed excellent results, although biofeedback required a fewer number of sessions
