Through a perineal approach, one\u2010sided urethral mobilization was performed with penile invagination to access the entire anterior urethra. Oral mucosa graft (OMG) or penile skin graft (PSG) was used as the urethral substitute. Success was defined as passing flexible cystoscopy without resistance and voiding without additional interventions. Patient\u2010reported outcomes were assessed using the urethral stricture surgery patient\u2010reported outcome measure (USS\u2010PROM), Sexual Health Inventory for Men (SHIM), and EuroQol\u20105 dimensions (EQ\u20105D) questionnaires. Follow\u2010up evaluations were conducted at 3, 6, and 12\u2009months postoperatively and then annually.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The median stricture length was 44\u2009mm (IQR 27\u201384). At a median follow\u2010up of 12\u2009months (IQR 6\u201334), the overall success rate was 89.7% (80.0% for OMG and 95.8% for PSG). Significant improvements were observed in maximum flow rate, post\u2010void residual volume, lower urinary tract symptoms (LUTS) score, LUTS\u2010related quality of life, EQ\u20105D score, and EQ\u2010visual analog scale (all <jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001).
