A new system for performing urethral pressure profiles, the fluid bridge test and micturitional urethral pressure profiles has been designed based on the use of a microcomputer. The method described has not only led to major improvement in the presentation and accuracy of these tests but for the first time urethral profilometry has been adapted to detect sphincter incompetence and obstruction in 1 simple method. The fluid bridge test was performed on 46 men and 18 women. The results suggested that this test was excellent for urodynamic evaluation of retrograde ejaculation, post-prostatectomy incontinence and vesicourethral neuropathy, and its value was confirmed in women with stress incontinence. Micturitional urethral pressure profiles were performed in 38 men and 2 women. Not only was this test found to correlate well with conventional methods of detecting obstruction but it was able to diagnose urinary outflow obstruction in patients with equivocal pressure/flow studies and patients with acontractile detrusors. It also allowed diagnosis of the site of obstruction in men with vesicourethral neuropathy without the need for radiological screening.
基于微型计算机的应用，设计了一种新的系统来进行尿道压力分布图、液桥试验和排尿期尿道压力分布图。所描述的方法不仅使这些测试的呈现和准确性有了重大改进，而且尿道压力测定首次通过一种简单方法得以应用于检测括约肌功能不全和梗阻。对46名男性和18名女性进行了液桥试验。结果表明，该试验对于逆行射精、前列腺切除术后尿失禁和膀胱尿道神经病变的尿动力学评估非常出色，其价值在压力性尿失禁女性中得到了证实。对38名男性和2名女性进行了排尿期尿道压力分布图检查。不仅发现该试验与检测梗阻的传统方法相关性良好，而且能够诊断压力/流量研究结果不明确的患者以及逼尿肌无收缩患者的尿路流出道梗阻。它还能够在无需放射学筛查的情况下诊断膀胱尿道神经病变男性的梗阻部位。
