The aim of the study was to test the reproducibility of a new method of determining cough-induced leak-point pressure (CILPP). A cough-induced increased in intra-abdominal pressure was recorded vaginally in 26 women with stress incontinence and urinary leakage was detected electronically. CILPP determinations and short-term pad tests were carried out on two different occasions. Reproducibility is expressed by a coefficient of repeatability as limits of agreement. These indicate that, for 95% of the cases, a repeat measurement of CILPP will be between 0.72 and 1.28 times the first measurement. The coefficient of variation was 11.2%. There was a moderate inverse correlation between pad-test data and CILPP. It was concluded that the new method allows for an accurate determination of CILPP, which represents a quantitative and dynamic assessment of urethral function. The reproducibility of the method appears to be better than that of pad tests and standard urodynamic parameters. The correlation with pad-test data gives support to the validity of the method.
本研究的目的是测试一种测定咳嗽诱发漏点压力（CILPP）新方法的可重复性。对26名压力性尿失禁女性经阴道记录咳嗽引起的腹内压升高，并通过电子方式检测尿液泄漏。在两个不同时间点进行CILPP测定和短期护垫试验。可重复性用重复性系数表示为一致性界限。这表明，在95%的病例中，CILPP的重复测量值将在首次测量值的0.72至1.28倍之间。变异系数为11.2%。护垫试验数据与CILPP之间存在中度负相关。得出的结论是，新方法能够准确测定CILPP，这代表了对尿道功能的定量和动态评估。该方法的可重复性似乎优于护垫试验和标准尿动力学参数。与护垫试验数据的相关性支持了该方法的有效性。
