Background/Aims/ Objectives: To report the outcome of staged urethroplasty with buccal mucosa and vascularised scrotal flap after failed hypospadias surgery. METHODS: n = 35. INCLUSION CRITERIA: destroyed urethral plate, deficient local skin, fistula and penile deviation. Five out of 35 patients also had a secondary proximal stricture. Stage 1: excision of scarred tissue and fistulae, correction of the penile deviation through dorsal plication and the ventral placement and quilting of buccal graft. Stage 2: tubularisation of the neourethral plate; in 20 patients with deficient penile skin a vascularised scrotal flap was developed and transferred on the tubularised urethra. In 5 patients, the proximal stricture was repaired during a separate operation by using buccal graft, the distal urethra was marsupialised. The repair of the distal urethra was performed later as described above. RESULTS: Thirty-three patients are recurrence-free without further interventions; successful reoperation was done in 2 cases. COMPLICATIONS: 1 graft necrosis; 1 coronary fistula; 1 scrotal flap necrosis and 1 case of hematoma. CONCLUSIONS: Complicated strictures after multiple failed hypospadias repair are well managed by using buccal graft. The vascularised scrotal flap is a very useful tool in case of deficient and scarred penile skin and could explain the low rate of fistula formation in our series.
