Voiding Dysfunction in Parkinson's Disease

Abstract
A micturitional history of unselected 110 patients with Parkinson's disease revealed that 66 (60%) had urinary symptoms such as irritative in 28%, obstructive in 11%, and both symptoms in 21%. The frequency of urinary symptoms statistically correlated with severity of the disease, but not with the duration of illness and no sexual difference was noted. A urodynamic study was conducted in 39 patients and 7 had residual urine of 30 ml or more, 19 had detrusor hyperreflexia, 19 had a small bladder capacity and only 1 had detrusor‐sphincter dyssynergia. The results indicate that the disturbed urine storage is more frequent and to a severer degree than that of urine evacuation in Parkinson's disease.
