Urinary dysfunction with detrusor hyperactivity in women with Parkinson's disease cannot be blamed as a factor of worsening motor performance.

INTRODUCTION: Detrusor hyperactivity is the leading cause of urinary dysfunction in Parkinson's disease (PD). There are few studies correlating PD clinical aspects with this autonomic feature. METHODS: A cohort of 63 women with PD were prospectively examined for assessment of clinical aspects and disease severity using unified Parkinson's disease rating scale and Hoehn-Yahr scale, respectively. The urologic function was evaluated by the urodynamic study. Two groups were categorized at this time - groups with and without detrusor hyperactivity. After seven years, the same parameters were re-evaluated. RESULTS: Progression of the disease on mental scores was found in the group with detrusor hyperactivity. On follow-up, clinical symptoms and severity did not show significant worsening between the groups. CONCLUSION: Detrusor hyperactivity is a frequent urodynamic finding in PD, and even though it is associated with dopaminergic dysfunction, it cannot be blamed as a factor of worsening motor performance, but is probably associated with poor cognitive and mental prognosis.

Introdução Hiperatividade detrusora (HD) é a principal causa de disfunção urinária na doença de Parkinson e poucos estudos correlacionam aspectos clínicos da doença com este componente autonômico. Métodos Foi avaliada uma coorte de 63 pacientes com DP quanto aos aspectos clínicos e gravidade global da doença utilizando as escalas UPDRS e Hoehn-Yahr. A função urológica foi avaliada através de estudo urodinâmico. Foram então categorizados dois grupos: pacientes com e sem HD. Após sete anos os mesmos parâmetros foram reavaliados. Resultados Houve progressão da doença quanto aos escores mentais no grupo com HD. Na reavaliação dos grupos os sintomas motores não evidenciaram piora significante. Conclusão HD é um achado urodinâmico frequente em pacientes com DP. Embora associada à disfunção dopaminérgica, HD não pode ser considerada fator de risco para piora do desempenho motor, mas provavelmente está associada com pior prognóstico mental e cognitivo. .
