Urethral pressure was investigated by a method which allowed simultaneous measurement of the cross-sectional area. In healthy women a pressure range of 25-140 cm H2O was recorded at one urethral site as a response to the circumstances under which the measurement was performed. The pressures obtained were related to the degree of urethral distension and to the time after the change in distension. Measuring urethral pressure at one specific degree of distension results in one specific pressure value according to the dimensions of the measuring probe. However, this specific pressure value cannot be considered to supply more information on urethral sphincter function than any other pressures included in a range which can be obtained by changing the circumstances under which the measurement are carried out. More provocative methods of pressure measurement which simulate some of the physiological conditions of the urethra may provide more information on sphincter efficiency.
采用一种能同时测量横截面积的方法对尿道压力进行了研究。在健康女性中，在一个尿道部位记录到的压力范围为25 - 140厘米水柱，这是对测量时所处环境的一种反应。所获得的压力与尿道扩张程度以及扩张变化后的时间有关。根据测量探头的尺寸，在一个特定的扩张程度下测量尿道压力会得到一个特定的压力值。然而，不能认为这个特定的压力值比通过改变测量环境所能获得的一系列压力中的任何其他压力能提供更多关于尿道括约肌功能的信息。更具激发性的压力测量方法，即模拟尿道的一些生理状况，可能会提供更多关于括约肌效率的信息。
