Cystometric, sphincter and electromyelographic abnormalities in Parkinson's disease

Abstract

Bladder function was studied in 24 patients with a diagnosis of parkinsonism using cystometry, sphincter electromyography, flowmetry and electromyelography. A high incidence of disturbances in detrusor function and sphincter control was documented and the signal tracing studies showed prolonged conduction times, giving evidence of peripheral neuropathy. The abnormalities of detrusor function were ascribed to the lesion of the basal ganglia, whereas the sphincter disturbances indicate impairment of the corticospinal tract as a result of Parkinson's disease.
