An Increase of Neuropeptide Y But Not Nitric Oxide Synthase-Immunoreactive Nerves in the Bladder Neck from Male Patients with Bladder Neck Dyssynergia

Abstract

It is suggested that the increase in density of protein gene product 9.5- and neuropeptide Y-immunoreactive nerves, part of the sympathetic contractile system of the bladder neck, may exacerbate bladder outlet obstruction and thus play a role in the pathogenesis of BND.
