title: Single-stage dorsal inlay full-thickness genital skin grafts for hypospadias reoperations: extended follow up.
abstract: OBJECTIVE
  To report our extended experience with single-stage genital skin graft urethroplasty for complex hypospadias reoperations.
  
  
  METHODS
  Thirty-one patients with failed hypospadias surgery were included. The urethral plate had been removed or was scarred in all. After excision of fibrotic tissue a free full-thickness skin graft was quilted to the corpora cavernosa. The neourethra was then tubularized followed by glanuloplasty. Voiding cystograms, urethral ultrasound and flow measurements were performed in all. Outcome was considered a failure when postoperative instrumentation was needed.
  
  
  RESULTS
  Follow up was 78.45 +/- 18.18 months. Shaft skin was used in 13 and internal prepuce in 18. Average graft length was 3.66 +/-1.56cm. Eighteen patients required glanuloplasty. Initial graft healing was successful in all. There was no postoperative infection involving the inlay. We did not note complications from the graft donor sites. Four patients underwent redo surgery yielding a complication rate of 12.9%. Urethral stricture of the proximal anastomosis was most frequent.
  
  
  CONCLUSIONS
  This single-stage approach using dorsal inlay skin grafts is reliable, creating a substitute urethral plate in the long term. Complication rates are equivalent to those of staged strategies. This is a safe option for hypospadias reoperations if the urethral plate is compromised.
