Preoperative bladder artery embolization may reduce tumor vascularity and facilitate subsequent TURBT; however, comparative evidence regarding its perioperative benefits and safety remains limited. This study evaluated the perioperative outcomes of preoperative bladder artery embolization followed by TURBT within 24\u00a0h in patients with bladder tumors measuring\u2009\u2265\u20093\u00a0cm.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Among 75 eligible patients, 27 underwent preoperative bladder artery embolization followed by TURBT and 48 underwent TURBT alone.
