Abstract:
A surgical procedure is described in which the canine bladder was divided into body and base. The two-chambered bladder thus formed was used to assess the effect of sympathomimetic drugs in situ. Stimulation of either alpha- or beta-receptors produced a change in pressure in both chambers. The bladder base showed a greater sensitivity to alpha-receptor stimulation than did the body of the bladder. No difference in sensitivity to beta-receptor stimulation was noted between body and base.
