Supplemental Material for: Intraoperative factors associated with de novo overactive bladder after Holmium Laser enucleation of the prostate

However, a subset develops de novo OAB postoperatively, which may significantly compromise QOL. Despite its clinical relevance, evidence regarding the incidence of and perioperative factors contributing to de novo OAB after HoLEP remains limited.</p><p dir="ltr">Methods： The present study included 536 patients who underwent HoLEP between April 2013 and September 2023.

Among them, 175 patients without preoperative OAB were eligible for analysis. </p><p dir="ltr">Results： De novo OAB was identified in 18 of 175 patients (10.3%). Baseline demographic and preoperative characteristics did not significantly differ between the groups. Intraoperatively, patients who developed de novo OAB exhibited shorter enucleation times, whereas the durations of other intraoperative procedures were significantly longer.
