一、引言膀胱尿道的压力测定,是研究膀胱和尿道功能的重要手段之一。对有下尿路症状的病人,特别是尿失禁病人的估价中,尿道的作用是决定性的。而估价尿道功能障碍最重要的方法之一是尿道压力剖面图。尿道是一个管状器官。静止状态时,由于它的纤维弹性和肌肉层的连接效应,它是 First, the introduction of bladder pressure measurement of the urethra, bladder and urethral function is an important means of study. The role of the urethra is decisive for the evaluation of patients with lower urinary tract symptoms, especially urinary incontinence. One of the most important ways to evaluate urethral dysfunction is the urethral pressure profile. The urethra is a tubular organ. It is, at rest, because of its fibrous elasticity and the muscular layer’s connecting effect
