Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <sec id="abs1-1" sec-type="section"> <title>Objective</title> <p>To determine the test–retest repeatability of the urodynamic parameters commonly utilized in ambulatory urodynamics (AM) for patients with neurogenic lower urinary tract dysfunction (NLUTD).</p> </sec> <sec id="abs1-2" sec-type="section"> <title>Methods</title> <p>A test–retest repeatability study was performed on 64 consecutive patients with stable spinal cord injuries who underwent two AM studies 24 hr apart.</p> </sec> <sec id="abs1-3" sec-type="section"> <title>Results</title> <p>The mean age was 43.2 years, with 47 males and 17 females. A significant intraclass correlation coefficient (ICC) was found between the two studies with respect to the functional bladder capacity (FBC; 0.74), the maximum detrusor pressure during the involuntary detrusor contraction (P<sub>detmaxIDC</sub>; 0.84), and the post‐void residual (PVR; 0.76). Of note, the ICC of the end filling detrusor pressure (P<sub>detfill</sub>) was not significant (0.25). The correlation with respect to the presence of involuntary detrusor contraction (IDC) was significant but low (κ = 0.40). Based on the logistic regression analysis, the variables that influenced the concordance with respect to the presence of the IDC were P<sub>detmaxIDC</sub> (directly) and P<sub>detmax</sub> (inversely). The variable that that influenced the concordance with respect to P<sub>detmaxIDC</sub> was PVR (directly). The variable that influenced the concordance with respect to PVR was the FBC (directly).</p> </sec> <sec id="abs1-4" sec-type="section"> <title>Conclusions</title> <p>AM is reliable for the reproduction of the main urodynamic parameters investigated in patients with NLUTD, except for the end filling detrusor pressure, which was a non‐reliable parameter. The concordance of AM can be improved primarily by taking into account the values of the maximum detrusor pressure during involuntary detrusor contraction (P<sub>detmaxIDC</sub>). Neurourol.
