Excluding the influence of changing urine flow by ligating the renal vein, canine electroureterographic studies were conducted to evaluate the effects of autonomic drugs upon the ureteral function. Intra-aortic administration of epinephrine, norepinephrine, phenylephrine, some amounts of acetylcholine, and dimethylphenylpiperazinium (DMPP) accelerated ureteral peristalsis. In the preadministration of phentolamine, epinephrine prolonged discharge intervals, and the response was suggestive of β effect. Phentolamine, propranolol, neostigmine, atropine, hexamethonium and tetrodotoxin caused no changes in electroureterograms.
