title: Factors predicting success in hypospadias repair using preputial flap with limited pedicle mobilization (Asopa procedure).
abstract: OBJECTIVE
  To analyze the objective factors determining success in hypospadias repair by the Asopa technique of limited preputial pedicle mobilization.
  
  
  METHODS
  This was a prospective study involving a cohort of 48 patients (age range 1-19 years) who underwent hypospadias repair in a tertiary care teaching institution, with a follow-up of 20-58 months. Patient inclusion criteria were absence of past history of any local surgery with urethral plate less than 6 mm and hooded prepuce.
  
  
  RESULTS
  At a median follow-up of 33.5 months, the overall complication and fistula rates were 22.9% and 16.7%. Complication and fistula rates were 40% and 30% with tube repairs vs. 18.4% and 13.2% with onlay repairs.
  
  
  CONCLUSIONS
  In patients unsuitable for Snodgrass repair, the Asopa technique of transverse preputial flap repair provides reasonably good results. Patients with proximal hypospadias, conical glans configuration, tube repairs, and more advanced age had higher complication rates with transverse preputial flap repair.
