Summary A new technique for recording of the urethral closure pressure profile using gas‐inflation and simultaneous EMG‐recording from the urethra is described. With the present technique, the parameters of the urethral closure pressure profile in healthy volunteers were in accordance with previous reports using water‐infusion. The effect of α‐adrenergic blockade on the pressure profile was studied in a series of patients. Half of the patients showed a marked reduction of the intraurethral pressure in the presphincteric part of the profile after α‐adrenergic blockade. This indicated that sympathetic innervated smooth musculature gives a significant contribution to the total intraurethral pressure.
