通过微传感器技术记录了20名无泌尿系统症状的女性和120名经尿动力学证实的真正压力-失禁的女性在休息和应激时的尿道压力测量。在无症状的女性中，静息剖面值在压力下基本保持不变，因为100%的腹内压力上升到近四分之三的功能尿道长度。虽然大多数人在膀胱颈部水平保持自制，但这些对照组中有25%的人在压力下表现出膀胱颈部张开的迹象。压力失禁患者表现出压力传递比的不足，这在确定症状时似乎具有“全有或无”的特征。静止状态下最大尿道闭合压力的幅度和稳定性、应激反应下尿道闭合压力损失的程度以及腹内压力上升的程度相互作用，决定了症状的严重程度或“禁尿边缘”。
Urethral pressure measurements were recorded at rest and during stress by a microtransducer technique in 20 women without urinary symptoms and 120 women with urodynamically proven genuine stress in‐continence. In the symptom‐free women the resting profile values were largely maintained during stress, as a consequence of 100% transmission of intra‐abdominal pressure rises to the proximal three‐quarters of the functional urethral length. Whilst the majority maintained continence at the bladder neck level, 25% of these controls showed evidence of bladder neck opening during stress. The stress‐incontinent patients showed a deficiency of pressure transmission ratios which appeared to have an ‘all or none’ character in the determination of symptoms. The amplitude and stability of the maximum urethral closure pressure at rest, the extent of urethral closure pressure lost in response to stress, and the extent of intra‐abdominal pressure rises interact to determine the severity of symptoms or ‘margin to continence’.
