Influence of sympathetic tonus and plasma noradrenaline on urethral pressure
Scandinavian Journal of Urology and Nephrology
|January 1, 1981
Abstract:
The relative influence of circulating noradrenalin and sympathetic tonus on urethral pressure was investigated by intravenous administration of noradrenalin and clonidine. Raising circulating noradrenalin concentrations by noradrenalin infusion had only a relatively minor effect on urethral pressure, indicating that urethral pressure is not controlled by circulating noradrenalin. Besides depression of sympathetic tonus and urethral pressure, clonidine reduced striated anal sphincter activity.
