Reproducibility of a new method to determine cough-induced leak-point pressure in women with stress urinary incontinence.
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.
