Effects of atropine, glucagon, and bethanechol on urodynamics of continent cecal urinary reservoir before and after complete, partial, and sham detubularizations in dog

摘要

AbstractEffects of muscarinic receptor blockade (atropine), stimulation (bethanechol), and bowel smooth muscle relaxant (glucagon) on the Urodynamics of the continent cecal urinary reservoir in a tube form and after complete, partial, and sham detubularizations were studied using dogs. Complete detubularization significantly increased capacity and decreased spontaneous motor activity, whereas the other types of detubularization had no significant effects on them. Neither atropine nor glucagon had influence on the basal pressure, but they increased the capacity and the volume at which the first pressure wave appeared and decreased the wave amplitude. After detubularization glucagon further decreased uninhibited contractions while atropine totally abolished them. The highest capacity and lowest motor activity was gained when atropine or glucagon was given in cases with detubularized pouch demonstrating an additive effect of the detubularization and drug. Also, bethanechol increased the motor activity and decreased the volume in detubularized pouches. It is suggested that when hyperactivity of intestinal reservoir is a problem in a patient with a detubularized cecal pouch, orally administered anticholinergic or bowel smooth muscle relaxing drugs may be useful in management. © 1993 Wiley‐Liss, I
