We measured urethral compliance in 57 patients using a catheter of increasing diameter. The measurement makes it possible to differentiate clearly between rigidity and hyperlaxity of the female urethra. In both instances, the initial pressure (Po) is lower than normal, but the rate of pressure increase (a), with larger catheter sizes, is significantly higher in cases of urethral rigidity and on the contrary parallel to normal in cases of hyperlaxity. This distinction allows for more accuracy in the determination of therapeutic indication. An inversely proportional correlation was found between the initial urethral pressure and the rate of pressure increase (r = 0.74). The initial pressure is generally lower in older women (r = 0.56).
我们使用直径逐渐增大的导管对57例患者的尿道顺应性进行了测量。该测量能够清晰地区分女性尿道的僵硬和过度松弛。在这两种情况下，初始压力（Po）均低于正常水平，但随着导管尺寸增大，尿道僵硬时压力升高速率（a）显著更高，而在尿道过度松弛时则与正常情况平行。这种区分有助于更准确地确定治疗指征。发现初始尿道压力与压力升高速率之间存在负相关（r = 0.74）。老年女性的初始压力通常较低（r = 0.56）。
