PURPOSE
Related values of pressure and cross-sectional area in the proximal urethra were measured in patients with bladder outlet obstruction. Urethral opening pressure and elastance (the inverse of compliance) were estimated.
MATERIALS AND METHODS
We studied 15 men with standard urodynamic examinations. The pressure-to-cross-sectional area relationship in the prostatic urethra was determined using a special probe.
RESULTS
Elastance varied significantly along the studied portion of the urethra, with higher values found in the sphincter area. The estimated urethral opening pressure appeared high compared to that in unobstructed cases and without variation along the prostatic urethra.
CONCLUSIONS
The most important effect of prostatic obstruction appears to be the increased urethral opening pressure.
目的
测量膀胱出口梗阻患者近端尿道压力和横截面积的相关数值。估算尿道开口压力和弹性（顺应性的倒数）。
材料与方法
我们对15名男性进行了标准尿动力学检查。使用特殊探头测定前列腺尿道的压力与横截面积关系。
结果
弹性在尿道研究段显著变化，在括约肌区域数值更高。与无梗阻病例相比，估算的尿道开口压力显得较高，且沿前列腺尿道无变化。
结论
前列腺梗阻最重要的影响似乎是尿道开口压力增加。
