A new technique for simultaneously recording urethral closure pressure and cross sectional area profile is described. The cross sectional area of the urethra could be measured using the field gradient principle. The procedure was performed readily in male patients and the recordings can be graphically presented during measurement. A high degree of reproducibility using this method was obtained. Typical recordings of control subjects was well as patients with pathology were obtained using this technique. The results of this study show that the maximum urethral closure pressure obtained was 60.8 + 3.4 mmHg and functional profile length, 4.8 + 0.4 cm. Internal meatus cross sectional area was 0.67 + 0.04 cm2 and the minimum urethral cross sectional area was 0.12 + 0.02 cm2. This method has been shown to be readily applicable in measuring urethral closure pressure in males and can potentially be used as a tool of comparing the functional parameters of pressure with the anatomical value of diameter.
本文描述了一种同时记录尿道闭合压和横截面积轮廓的新技术。尿道横截面积可利用场梯度原理进行测量。该操作在男性患者中易于实施,且记录可在测量过程中以图形方式呈现。使用该方法获得了高度的可重复性。利用此技术获得了正常受试者以及有病理状况患者的典型记录。本研究结果显示,所获得的最大尿道闭合压为60.8±3.4 mmHg,功能轮廓长度为4.8±0.4 cm。尿道口横截面积为0.67±0.04 cm²,最小尿道横截面积为0.12±0.02 cm²。已证明该方法易于应用于测量男性尿道闭合压,并有可能用作比较压力功能参数与直径解剖学值的工具。
