A QUANTITATIVE STUDY OF ATROPINE-RESISTANT CONTRACTILE RESPONSES IN HUMAN DETRUSOR SMOOTH MUSCLE, FROM STABLE, UNSTABLE AND OBSTRUCTED BLADDERS

Abstract

It is concluded that purinergic, atropine-resistant contractions are present in some types of dysfunctional bladder, and these are not caused by a differential sensitivity of the muscle to ATP and cholinergic agonists.
