Single-stage correction of posterior hypospadias (178 cases). Comparison of three techniques: free skin graft, free bladder mucosal graft, transverse pedicle preputial graft.
Three techniques have been developed for single-stage repair of posterior hypospadias: free skin grafts, free bladder mucosal grafts, and pedicle preputial grafts. This multicenter retrospective study of 178 children who underwent surgery for posterior hypospadias was designed to compare the results achieved with these procedures. Free skin grafts (15 cases) resulted in the most frequent complications, and in particular the most severe strictures; in our opinion this technique should be abandoned. Pedicle preputial grafts (133 cases) gave the greatest number of successes from the outset, and should be preferred whenever the dimensions of the prepuce are sufficient for urethroplasty. Results with bladder mucosal grafts (30 cases) were not as good as with preputial grafts, but this technique remains the only solution when the meatus is in a very posterior position, and for children who have already undergone multiple operations.
