Deep Convolutional Neural Networks scheme combined with a short\u2010time Fourier transform algorithm was trained to perform an accurate diagnosis of BOO and DUA, utilizing five\u2010channel urodynamic data (consisting of uroflowmetry, urine volume, intravesical pressure, abdominal pressure, and detrusor pressure). We used fivefold cross\u2010validation, constructing training and internal test sets from 1725 patients from Renmin Hospital of Wuhan University (RHWU) at a 4:1 ratio, and used an independent external validation set consisting of 224 patients from The Central Hospital of Wuhan (TCHO) to build and evaluate the DI model. We further conducted subgroup analyses to provide a more detailed description of the AI model's interpretability regarding urodynamics.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The AUC scores of BOO and DUA, which were measured through the STFT\u2010based deep learning method, were 0.945\u2009\u00b1\u20090.020 and 0.929\u2009\u00b1\u20090.039 in RHWU and 0.881 and 0.850 in TCHO, respectively.
