SUMMARY— The urethral closure pressure profile (UCPP) was recorded in 100 consecutive patients using both the water infusion and the carbon dioxide infusion methods. Ninety‐one per cent of the patients complained of discomfort during CO 2 infusion. Thirty‐two of the CO 2 profiles were distorted due to patient discomfort or shortcomings in the design of the measuring system, and in these no quantitative comparisons could be made. In 68 cases the profile measurements were compared: average maximum closure pressures and functional urethral lengths were slightly less with the CO 2 but some individual variations were substantial. We concluded that unreliability and patient reaction make CO 2 infusion less suitable than H 2 O for measuring UCPP.
