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 as 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+3.4mmHg and functional profile length, 4.8+0.4cm. Internal meatus cross sectional area was 0.67+0.04cm<SUP>2</SUP> and the minimum urethral cross sectional area was 0.12+0.02cm<SUP>2</SUP>. 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.
