title: Which type of urethroplasty in failed hypospadias repair? An 8-year follow up.
abstract: OBJECTIVE
  To report our 8-year follow up for redo hypospadias repair.
  
  
  METHODS
  A total of 56 patients with previous failed hypospadias repair were included in our study. Patients' data were analyzed regarding age, number of previous repairs, meatal location, procedure performed, operative time and complications. Patients were followed up for 3 to 102 (mean 52) months.
  
  
  RESULTS
  Patient age ranged from 15 to 204 (mean 90.7) months. Forty-two patients had a single previous hypospadias repair, eleven had two previous repairs and three had four previous repairs. Of the 56 patients, 16 underwent oral mucosal graft urethroplasty, 15 onlay island flap, 14 parameatal flap, 10 tubularized incised plate urethroplasty, and 1 tubularized preputial flap. Complications were encountered in 16 (28.5%) patients in the form of graft contracture in 3, meatal stenosis in 2, urethral stricture in 2 including the patient with tubularized flap, urethra-cutaneous fistula in 7, bleeding in 1 and skin disruption in 1. The final complication rate was 25%.
  
  
  CONCLUSIONS
  Decision making in redo hypospadias surgery depends mainly on local tissue availability and the degree of tissue scarring. The characteristics of oral mucosal graft make it suitable for urethroplasty in the absence of local donor tissues. A long-term follow up for redo hypospadias repair is required to assess the late neourethral stricture and residual penile curvature.
