title: Free graft two-stage urethroplasty for hypospadias repair.
abstract: OBJECTIVE
  To evaluate the effectiveness of free graft transplantation two-stage urethroplasty for hypospadias repair.
  
  
  METHODS
  Fifty-eight cases with different types of hypospadias including 10 subcoronal, 36 penile shaft, 9 scrotal, and 3 perineal were treated with free full-thickness skin graft or (and) buccal mucosal graft transplantation two-stage urethroplasty. Of 58 cases, 45 were new cases, 13 had history of previous failed surgeries. Operative procedure included two stages: the first stage is to correct penile curvature (chordee), prepare transplanting bed, harvest and prepare full-thickness skin graft, buccal mucosal graft, and perform graft transplantation. The second stage is to complete urethroplasty and glanuloplasty.
  
  
  RESULTS
  After the first stage operation, 56 of 58 cases (96.6%) were successful with grafts healing well, another 2 foreskin grafts got gangrened. After the second stage operation on 56 cases, 5 cases failed with newly formed urethras opened due to infection, 8 cases had fistulas, 43 (76.8%) cases healed well.
  
  
  CONCLUSIONS
  Free graft transplantation two-stage urethroplasty for hypospadias repair is a kind of effective treatment with broad indication, comparatively high success rate, less complications and good cosmatic results, indicative of various types of hypospadias repair.
