Neurogenic lower urinary tract dysfunctions are common in patients with multiple sclerosis and for most of them urinary dysfunction has the most negative impact on their social life. No correlation exists between clinical urinary symptoms and urodynamic patterns. Abnormal urodynamic patterns may be present in asymptomatic patients. Both clinical and urodynamic findings may change during the course of the illness. Early diagnostic approach and scheduled follow-ups are mandatory in order to prevent upper urinary tract complications and improve quality of life (QoL).
