title: Tubularized incised plate urethroplasty with dorsal inlay graft prevents meatal/neourethral stenosis: a single surgeon's experience.
abstract: OBJECTIVE
  Snodgrass tubularized incised plate urethroplasty (SUP) is versatile and has good cosmesis. However, postoperative meatal/neourethral stenosis (M/N-S) is common enough for some surgeons to add a dorsal inlay graft (DIG) harvested from the inner prepuce and sutured to cover the longitudinal midline incision of the urethral plate. This is the first formal assessment of the effectiveness of DIG for preventing M/N-S.
  
  
  METHODS
  We reviewed the medical records of 100 consecutive SUP cases performed by a single surgeon between 2003 and 2010 comparing SUP + DIG (S + D group, n = 50) with SUP - DIG (S - D group, n = 50). Mean follow-up was 3.6 years. Data were analyzed statistically using the χ(2), 2-way ANOVA, and Mann-Whitney tests, with P < .05 considered significant.
  
  
  RESULTS
  Severity of hypospadias and type of SUP were similar. Mean age at SUP was 3.3 years in S + D and 3.6 years in S-D (P = NS). There were 4 complications in the S + D group: urethrocutaneous fistula (n = 3) and neourethral stenosis without diverticulum (n = 1). There were 15 complications in the S-D group : meatal stenosis (n = 2), neourethral stenosis with or without diverticulum (n = 6), urethrocutaneous fistula (n = 7) (P < .01). M/N-S was significantly less in the S + D group (1 vs 8; P < .05).
  
  
  CONCLUSIONS
  We strongly recommend that DIG be performed routinely during SUP.
