title: Comparison of the perimeatal-based flap (Mathieu) and the tubularized incised-plate urethroplasty (Snodgrass) in primary distal hypospadias.
abstract: OBJECTIVE
  To determine whether the perimeatal-based flap technique or the tubularized incised-plate repair is the more appropriate treatment for distal hypospadias in terms of fistula rate, cosmesis of the meatus and operative duration.
  
  
  METHODS
  Between July 1997 and August 1998, 60 children (none of whom had previously undergone a procedure for hypospadias) underwent primary distal hypospadias repair in a prospective randomized trial. Thirty patients were allocated to undergo a Mathieu repair (mean age 24.9 months, range 9-72) and 30 a Snodgrass procedure (mean age 23.1 months, range 7-19). The mean follow-up was 15.4 months.
  
  
  RESULTS
  The mean duration of surgery was significantly lower for the Snodgrass procedure than for the Mathieu repair (75 vs 115 min, P < 0.05). Three children undergoing a Mathieu repair had complications (two a urethrocutaneous fistula and one a meatal stenosis), compared with only one in the Snodgrass group (glanular dehiscence). The resultant meatus was slit-like in all patients undergoing the Snodgrass repair whereas those with a Mathieu repair had a rounded and horizontal meatus.
  
  
  CONCLUSIONS
  The overall complication rate was lower and the surgery significantly quicker with the Snodgrass urethroplasty, which also had a better cosmetic outcome. The Snodgrass technique is recommended as a primary treatment for distal hypospadias.
