The effect of alpha-adrenoceptor stimulation and blockade on the static urethral sphincter function in healthy females.

The influence of noradrenaline and prazosin on the urethral closure function was evaluated in 10 healthy female volunteers. Measurements of pressure at varying cross sectional areas were carried out at the bladder neck, in the high pressure zone, and in the distal urethra. Prazosin reduced the static pressure, predominantly in the midportion of the urethra… CONTINUE READING
