title: Use of double pigtail stent in hypospadias surgery.
abstract: OBJECTIVE
  Various types and materials of stents have been used for urinary diversion in hypospadias surgery. We evaluated whether double pigtail stents are superior to straight silicone stents.
  
  
  METHODS
  We conducted a retrospective chart review of all patients who underwent hypospadias surgery with straight silicone or double pigtail stents between November 1997 and October 2005. Comparisons were made between the two groups specifically with regard to the complication rates.
  
  
  RESULTS
  A total of 86 patients were included. The complication rates in patients who received double pigtail stents were significantly reduced as compared with those who received straight silicon stents. There was less wound disruption associated with early stent dislodgement in the double pigtail group compared with the straight silicone group (3.2%vs. 17.4%, p< 0.05). The rate of urethrocutaneous fistula was also lower in the double pigtail stent group (12.7%vs. 30.4%). Subjectively, there was also improved patient comfort and parent anxiety in the double pigtail stent group.
  
  
  CONCLUSIONS
  Double pigtail stent is a suitable material for urinary diversion in hypospadias surgery. It not only reduces patient discomfort, but also decreases complication rates in hypospadias surgery.
