In unanesthetized, normal rats, and rats with bladder hypertrophy following infravesical outflow obstruction, cystometry was performed to investigate the effects of spinal and peripheral administration of vasoactive intestinal polypeptide (VIP) on micturition. In addition, the direct effects of the peptide on isolated smooth muscle preparations of detrusor and urethra were studied. In normal animals, 10 micrograms. of VIP administered intrathecally as well as intra-arterially close to the bladder, but not intravenously, decreased micturition volume and bladder capacity, and facilitated spontaneous bladder contractions. In animals with bladder hypertrophy, the same dose of VIP intrathecally had similar effects on these three parameters, but the effects of VIP given intra-arterially were less pronounced. VIP given intravenously was ineffective. Hexamethonium 5 mg. x kg.-1 given intraarterially did not block the stimulatory effect of VIP 10 micrograms. given intra-arterially to normal animals. VIP had negligible effects on isolated detrusor muscle contracted by carbachol or electrical stimulation, or on urethral preparations contracted by noradrenaline. These results suggest that VIP has a facilitatory action on the micturition reflex at the spinal cord and ganglionic levels.
