Abstract
AbstractResting urethral pressure profile measurements and continuous urethrocystometry traces were carried out in a group of 24 patients by using both conventional microtransducer catheter and fibre‐optic microtransducer techniques in an effort to assess the repeatability of the various profile parameters and to investigate rotational variations in the recordings.The microtransducer technique resulted in profiles with significantly higher values for total profile length (TPL), functional profile length (FPL), length to peak pressure (LtPP), and maximum urethral pressure (MUP), with significantly lower variation in urethral pressure than the fibre‐optic technique. These findings applied in all transducer orientations, even though the microtransducer method showed a greater degree of rotational variation.When a standard catheter orientation was employed (with the transducer facing laterally in the urethra) the microtransducer technique showed significantly greater consistency of profile parameters when an analysis of variance technique was used.
