Reproducibility of Simultaneous Urethrocystometry Measured with Electronic Microtransducers

Abstract

The reproducibility of simultaneous urethrocystometry in time and different rotational positions has not been sufficiently investigated. A prospective study with 16 patients assessed for incontinence was carried out, urethrocystometry with electronic microtransducers being performed at 1- to 3-week intervals, and with the catheter rotated to four different positions. Six parameters were analyzed on urethral profiles at rest and under stress. The reproducibility of all parameters in time was excellent. A comparison of values obtained after rotating the catheter showed significant differences for some parameters, but without clinical relevance.
