Severe bleeding was defined as hemodynamic instability, hemoglobin decrease &gt;35 g\/L, or persistent gross hematuria. Patients were categorized as continued conservative treatment (CCT), negative RA with conservative recovery (RAN), or positive RA requiring transcatheter arterial embolization (TAE). Univariable and multivariable logistic regression analyses identified predictors of TAE, and receiver operating characteristic (ROC) analysis assessed discriminative performance.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results:<\/jats:title>\n                    <jats:p>\n                      Among 75 patients (65 men, 10 women; mean age 52.7 years), 8 (10.7%) were treated with CCT, 15 (20.0%) had negative RA (RAN), and 52 (69.3%) underwent effective TAE. Baseline demographic and perioperative parameters were comparable among groups, except for tract location, which was significantly associated with embolization (\n                      <jats:italic toggle=\"yes\">p<\/jats:italic>\n                      &lt; 0.001).
