Long-term evaluation of staged oral mucosa graft urethroplasty in children with reoperative hypospadias: functional and cosmetic outcomes during adolescence and early adulthood.
Staged oral mucosal graft urethroplasty gave a functionally patent neourethra in most children with failed hypospadias repair at 10+ years
Long-term evaluation of staged oral mucosa graft urethroplasty in children with reoperative hypospadias: functional and cosmetic outcomes during adolescence and early adulthood.
Failed hypospadias repair remains a challenging issue in pediatric urology due to tissue loss, scarring, and complex anatomy.
This study aims to evaluate the long-term functional and cosmetic outcomes of staged oral mucosal graft urethroplasty in children who have previously undergone unsuccessful hypospadias repairs.
A retrospective cross-sectional study was conducted assessing children who underwent staged oral mucosal graft (oral mucosal grafts) urethroplasty between January 2007 and December 2013 at our institution.
The mean age at first-stage surgery was 7.9 ± 2.8 years.
Bell-shaped curves were seen in 27 (39.7%), while obstructive curves were identified in 6 patients (8.8%).
The mean Hypospadias Objective Scoring Evaluation score was 10.3 ± 1.9, and the mean PPPS score was 9.4 ± 1.2, indicating satisfactory functional and cosmetic outcomes.
The most common complication was urethrocutaneous fistula, occurring in 11 patients (16.1%).
Oral mucosal graft urethroplasty provides excellent long-term functional and cosmetic outcomes in children with failed hypospadias repairs.
The high Hypospadias Objective Scoring Evaluation and PPPS scores, along with a low complication rate and durability through puberty, adolescence, and early adulthood, support oral mucosal grafts as a preferred tissue substitute in complex reoperative hypospadias surgeries.
