The urethral response to bladder filling has been studied by synchronous measurement of four points in the proximal urethra and bladder using microtip transducers. Twelve male patients with urodynamically proven bladder instability had falls in urethral closure pressure of 30 cm of water 3 s before the unstable detrusor contraction. There was a lack of awareness of the urethral relaxation, the sensation of urgency occurring only when the detrusor contracted. The suggestion is made that the sequence of events occurring in these patients with bladder instability is fundamentally no different from a normal voiding sequence and that it may be more appropriate to re-educate the muscles of the proximal urethra than to treat the detrusor instability.
通过使用微尖端换能器同步测量近端尿道和膀胱的四个点，对膀胱充盈时的尿道反应进行了研究。12名经尿动力学证实存在膀胱不稳定的男性患者，在逼尿肌不稳定收缩前3秒，尿道闭合压下降了30厘米水柱。患者未察觉到尿道松弛，仅在逼尿肌收缩时才出现尿急感。有人提出，这些膀胱不稳定患者发生的一系列事件与正常排尿序列在根本上并无不同，并且对近端尿道肌肉进行再训练可能比对逼尿肌不稳定进行治疗更为合适。
