[Electrical stimulation of the pelvic floor versus vaginal cone therapy for the treatment of stress urinary incontinence]. / Eletroestimulação funcional do assoalho pélvico versus terapia com os cones vaginais para o tratamento de incontinência urinária de esforço.

PURPOSE: to compare the effects of functional electrostimulation of the pelvic floor and therapy with cones in women with stress urinary incontinence (SUI). METHODS: randomized clinical study for which 45 patients with SUI were selected. The effects of functional electrostimulation of the pelvic floor were evaluated in the SUI treatment of 24 women, with the use of clinical data (micturition diary, pad test and a questionnaire about quality of life - I-QoL). The patients were submitted to two 20' weekly sessions for four consecutive months, under the supervision of a physiotherapist. The electrode used had 10 cm length and 3.5 cm width with a double metallic ring and a cylindrical shape, positioned in the medium third of the vagina. The electric parameters used were: intensity varying from 10 to 100 mA and 50 Hz of fixed frequency, with pulse duration of 1 ms. Also, we evaluated 21 patients who were submitted to vaginal cone treatment. The cone therapy was done with two 45 minute sessions per week. The cones' weight varied from 20 to 100 gr. RESULTS: there was no difference between the outcomes of electrostimulation of the pelvic floor and the vaginal cones for the treatment of SUI (p>0.05). After four months, there was a significant improvement in the I-QoL index of the patients treated both with electrostimulation (40.3 versus 82.9) or with the cones (47.7 versus 84.1). There was a significant decrease in pad weight in both groups, measured before and after the treatment (28.5 and 32 g versus 2.0 and 3.0 g for the electrostimulation and cone group, respectively). Finally, there was a significant decrease in the number of urinary leakage evaluated by the micturition diary in both groups (p<0.0001). CONCLUSIONS: both electrostimulation and vaginal cones were effective in the treatment of women with SUI.

Eletroestimulação funcional do assoalho pélvico versus terapia com os cones vaginais para o tratamento de incontinência urinária de esforço / Electrical stimulation of the pelvic floor versus vaginal cone therapy for the treatment of stress urinary incontinence

OBJETIVO: comparar os efeitos da eletroestimulação funcional do assoalho pélvico e da terapia com os cones em mulheres com incontinência urinária de esforço (IUE). MÉTODOS: estudo clínico randomizado. Selecionamos 45 pacientes com IUE, avaliamos os efeitos da eletroestimulação funcional do assoalho pélvico no tratamento da IUE em 24 mulheres empregando dados clínicos (diário miccional, pad test e questionário de qualidade de vida - I-QoL). As pacientes se submeteram a duas sessões semanais, com duração de 20 minutos cada, durante quatro meses consecutivos, com supervisão de uma fisioterapeuta. Foi utilizado eletrodo de aproximadamente 10 cm de comprimento e 3,5 cm de largura, com duplo anel metálico e formato cilíndrico, posicionado no terço médio da vagina. Os parâmetros elétricos utilizados foram: intensidade de corrente variando de 10 a 100 mA e frequência fixa em 50 Hz com duração de pulso de 1 mili/seg. Avaliamos também 21 pacientes que se submeteram ao tratamento com cones vaginais. A terapia com os cones foi feita em duas sessões semanais com duração de 45 minutos. O peso dos cones variou de 20 a 100 g. RESULTADOS: não houve diferença entre os resultados da eletroestimulação para o assoalho pélvico e da terapia com os cones vaginais para o tratamento da incontinência urinária de esforço (p>0,05). Observamos, após quatro meses, melhora significativa dos índices de qualidade de vida das pacientes tratadas com eletroestimulação (40,3 versus 82,9) e com os cones (47,7 versus 84,1). Houve diminuição significante do peso do absorvente (pad test) nos dois grupos antes e depois do término dos tratamentos (28,5 e 32 g versus 2,0 e 3,0 g, para o grupo da eletroestimulação e cones, respectivamente). Finalmente, houve diminuição significativa no número de perdas urinárias avaliadas pelo diário miccional nos dois grupos (p<0,0001). CONCLUSÕES: a eletroestimulação e os cones vaginais foram efetivos no tratamento de mulheres com IUE.
