Patients with Parkinson's disease have recently been reported to experience both urge urinary incontinence (overactive bladder) and stress urinary incontinence, the latter of which occurs when the pressure of the bladder exceeds that of the urethra. Vibegron is a highly selective novel \u03b2<jats:sub>3<\/jats:sub>\u2010adrenoceptor agonist approved for the treatment of overactive bladder. However, how \u03b2<jats:sub>3<\/jats:sub>\u2010adrenoceptor agonists affect urethral function remains unclear. In a clinical report, the urethral function of patients with Parkinson's disease was shown to be degraded. The present study aimed to investigate the effects of vibegron on lower urinary tract activity in a rat model of Parkinson's disease.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>In a rat model of Parkinson's disease induced by unilateral 6\u2010hydroxydopamine injection into the substantia nigra pars compacta, we examined the effects of vibegron on bladder and urethral activity.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Cystometric analysis revealed that, compared with vehicle injection, intravenous injection of 3\u2009mg\/kg vibegron significantly increased the inter\u2010contraction interval (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.05) and reduced voiding pressure (<jats:italic>p<\/jats:italic>\u2009&lt;\u2009.01).
