Summary The urethral pressure profile (UPP) is recorded by CO 2 ‐perfusion of the urethra at a rate of 120 ml/min. The curves are reproducible. Their features are practically identical with the shape of profiles written by liquid perfusion. The curves are absolutely calibrated. High flow perfusion and calibration make it possible to compare CO 2 ‐curves with each other and even with graphs executed by other methods.
