Sujeitos e métodos: para este ensaio clínico prospectivo, controlado e randomizado foram convidadas a participar do estudo 37 mulheres consultadas no ambulatório de uro-ginecologia do Hospital das Clínicas (HC) da UNICAMP, que cumpriram os critérios de inclusão e exclusão. Foram aleatoriamente alocadas em dois grupos. Grupo tratamento: as mulheres foram tratadas com o uso da eletroestimulação transcutânea do nervo tibial posterior (n = 21) e Grupo placebo: as mulheres tiveram os eletrodos alocados, mas sem passagem de corrente elétrica (n = 16). No primeiro contato com a paciente foi feito o convite para participar do estudo e realizada uma avaliação fisioterapêutica, incluindo preenchimento do diário miccional de três dias e dos questionários de qualidade de vida (ICIQ, KHQ e OABq). Na aplicação da técnica utilizou-se oito sessões de eletroestimulação transcutânea do nervo tibial posterior. Resultados: A noctúria apresentou melhora significativa no grupo tratamento (p=0,003) e uma tendência de maior melhora no grupo tratado (p=0,054). A frequência urinária diminuiu significativamente no grupo tratamento (p=0,003) e a urgência miccional diminuiu também em ambos os grupos (placebo:p=0,025 e tratamento:p=0,002). Com relação aos questionários utilizados, apenas o OABq foi responsivo, tanto no escore total (p=0,037), quanto no escore severidade (p=0,018). Conclusão: A eletroestimulação transcutânea do nervo tibial posterior é uma ferramenta eficaz no tratamento fisioterapêutico da Bexiga Hiperativa. / Abstract: The aim of this study was to evaluate the effect of the electrical stimulation of the posterior tibial nerve on the quality of life in women with overactiv bladder syndrome. Subjects and methods: thirty seven women from to Urogynecology Division of the Hospital das Clínicas de Campinas (HC/UNICAMP) were invited to participate in a prospective randomized trial. After screening inclusion and exclusion criteria, they were randomly placed in one of two groups: Treatment group: the women were submitted to tibial posterior nerve electrical stimulation (n = 21) and Sham group: the women had electrodes placed on the tibial posterior nerve, without stimulation (n = 16). At first, the patients were invited to participate in the study and submitted to a physiotherapeutic evaluation, including fulfilling a three days diary, quality of life questionnaires (ICIQ, KHQ an OABq). The approach of the treatment was eigth sessions of electrical stimulation on the posterior tibial nerve. Results: noctury was significantly improved in the treatment group (p=0,003). The urinary frequency was significantly improved in treatment group (p=0,003) and the urgency decreased significantly in both groups (sham:p=0,025 and treatment p=0,002). Comparing the questionnaires applied only the OABq was responsive in both scores, total score (p=0,037) and severity score (p=0,018). Conclusion: The posterior tibial nerve electrical stimulation is an effective physiotherapeutic treatment in overactive bladder. / Mestrado / Mestre em Cirurgia

Spinal cord injury (SCI) remains a significant cause for morbidity and mortality in North America. Bladder dysfunction following SCI is very common and could lead to severe complications including renal failure and autonomic dysreflexia (AD). AD involves life threatening episodes of hypertension in patients with SCI above T6 level. Current management protocols for AD are symptomatic and usually ineffective. Botulinum toxin-A (BTX-A), has been successfully used recently in SCI patients because it reduces the detrusor contractility via inhibiting acetylcholine release from efferent nerve endings. Recent evidence, however, suggests a sensory involvement via modulation of sensory neuropeptides, neurotransmitters, and receptors. It is still, however, unclear whether BTX-A can affect putative spinal neurons involved in AD. In this study we demonstrated that intravesical BTX-A treatment has blocked AD in rats with T4-SCI, and also provided a novel mechanism for the control of autonomic dysreflexia via a minimally invasive treatment modality.
