Urodynamics: Prone Vs. Seated Position

Overview

To demonstrate the feasibility of a pressure-flow study using a urinary condom with drainage tube in the sitting and lying position in everyday clinical practice and the comparability of the measured values with the "conventional" pressure-flow studies according to the ICS standard with regard to the diagnosis of outlet obstruction in men.

The study aims to investigate a change in the measured values of a pressure-flow measurement in male patients between the sitting and lying position using a urinary condom. This offers enormous added value for science, as both a technique for carrying out the measurement and the effect of positioning can be evaluated. Due to anatomical conditions, this project will only be carried out with male patients. By carrying out the individual measurements in different examination positions on the same patient, influences caused by the change in position can be verified. It enables direct comparison of the criteria for outlet obstruction in the same patient and thus leads to confirmation or rejection of the hypothesis that the outlet obstruction criteria can be used for measurements in the supine position in the same way as for the measurement in the sitting position described by ICS. This project is therefore based on the question of whether the known analysis criteria for outlet obstruction are equivalent to the measurements recommended by ICS in the sitting position in male patients in whom pressure-flow studies can only be performed in the supine position. In addition, the use of a urinal condom with a drainage line as an aid or technique during the measurement is being investigated.
