ABSTRACT

OBJECTIVE: To evaluate the presence of urinary symptoms in 77 patients with multiple sclerosis. METHODS: The neurological compromise and the degree of functional disability were evaluated through the Minimum Dossier of Disability for Multiple Sclerosis. The pertinent data for the urinary symptoms were collected through a directed survey. A urodynamic study was performed to evaluate bladder function. RESULTS: 81.8% of the patients had urinary symptoms, the most prevalent being the mixed syndrome (52%). Neurological involvement and functional disability were greater in the male patients and there was a higher incidence of urinary symptoms (91%). Urgency (66.6%), frequency (60.3%) and dysuria (53.8%) were the most common urinary symptoms. The complication rate was low; infection was the most common complication (14.28%) and was more prevalent in the females. Detrusor hyperreflexia (60%) was the most frequent urodynamic finding. CONCLUSIONS: Urinary symptoms are frequent in multiple sclerosis (81.8%), the most prevalent being the mixed syndrome. Neurological involvement and functional disability are greater in the male patients and there is a higher incidence of urinary symptoms. There is a significant correlation between the severity of neurological compromise (pyramidal and cerebellar) and the degree of functional disability and the presence of urinary symptoms.
