Disfunción vésico-esfinteriana en 108 casos de esclerosis múltiple

OBJECTIVE: To study vesicosphincteric dysfunction in 108 patients with multiple sclerosis. METHODS: We reviewed the clinical records of 108 patients with multiple sclerosis and analyzed those with voiding symptoms ascribable to multiple sclerosis. These patients underwent complete urodynamic assessment and complementary tests according to their symptoms. The Blaivas classification was used for the clinical classification of multiple sclerosis. RESULTS: 64 of the 108 patients presented voiding symptoms ascribable to multiple sclerosis (59.2%). The clinical features presented as episodes in 75% and were progressive in 25% of the cases. In 6% of the patients, the voiding symptoms were the first symptoms of multiple sclerosis. Urodynamic assessment showed detrusor hyperreflexia in 73% of the patients, hyporeflexia in 14%, and 13% showed normal urodynamics. All complications were infective; no patient showed upper urinary tract complications. CONCLUSIONS: Vesicosphincteric dysfunction in multiple sclerosis is frequent. Most of the patients present bladder hyperreflexia. The urological complications are usually infective. Involvement of the upper urinary tract is rare.
