Patients were classified using both the Abrams\u2013Griffiths (AG) nomogram and UPSTREAM derived thresholds. Subgroups stratified according to obstruction and contractility status were compared in terms of lower urinary tract parameters, particularly PVR values measured after spontaneous voiding and those measured after PFS. In addition, the ability of specific PVR threshold values to discriminate between obstruction and contractility states was analyzed using classifications based on nomograms.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      A total of 227 men were included (median age: 62 years).

Post PFS PVR\u2009&gt;\u2009100\u2009mL was significantly more frequent in underactive patients across both AG and UPSTREAM classifications and, according to AG, in obstructive patients. In addition, post PFS PVR\u2009&gt;\u2009200\u2009mL was significantly associated with DU in the UPSTREAM classification. ROC analysis demonstrated that post PFS PVR predicted DU with an AUC of 0.599 (95% CI: 0.522\u20130.677,\n                      <jats:italic>p<\/jats:italic>\n                      \u2009=\u20090.013); a 67.5\u2009mL threshold yielded 58% sensitivity and 58.3% specificity.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Post PFS PVR correlates more with DU, while spontaneous PVR is more associated with bladder outlet obstruction.
