A retrospective analysis of 100 Benign Prostatic Hyperplasia (BPH) patients treated with ThuFLEP was conducted. Perioperative data were analyzed, including prostate volume, operative time, and enucleation weight. Statistical methods included <jats:italic>T<\/jats:italic>-tests, chi-square tests, and linear regression. Learning curves were constructed using Loess regression, with box plots visualizing differences in operative time, efficiency, and enucleation ratio efficacy. Postoperative follow-up assessed changes in IPSS, Qmax, and urinary incontinence.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The learning curve analysis showed a significant reduction in operative time after 56 cases. Linear regression indicated a decrease in operative time (<jats:italic>R<\/jats:italic>\u2009=\u2009\u22120.5, <jats:italic>p<\/jats:italic>\u2009&amp;lt;\u20090.01) and improvements in efficiency (<jats:italic>R<\/jats:italic>\u2009=\u20090.14, <jats:italic>p<\/jats:italic>\u2009&amp;lt;\u20090.01) and enucleation ratio efficacy (<jats:italic>R<\/jats:italic>\u2009=\u20090.41, <jats:italic>p<\/jats:italic>\u2009&amp;lt;\u20090.01) with increased experience. Comparing the first and last 50 cases, operative time and enucleation efficiency significantly improved (<jats:italic>p<\/jats:italic>\u2009&amp;lt;\u20090.01). Postoperatively, 31% of patients experienced incontinence one week after catheter removal, but all recovered within 12 weeks.
