RESUMO
Objective To investigate the feasibility of urethral prefabrication with vaginal mucosa in female-to-male transsexuals and to compare the urologic complications after penile reconstruction in female-to-male transsexuals between prefabrication group and forearm group.Methods Prefabrication of the neourethra with tubed vaginal mucosal graft was performed for 22 female-to-male transsexual patients from 2007 to 2016,while radial forearm flap,known as the traditional tube-within-tube method,was used to construct the neourethra for other 31 cases.Results All of the reconstructed penises survived completely and allowed the patients to urinate while standing in the prefabrication group.Phalloplasty by using the vaginal mucosal graft for urethroplasty significantly decreased the donor scar,the duration of the second operation and the incidence rates of urologic strictures,comparing with the forearm group (P＜0.05).Conclusions It is reliable to use the prefabrication of the neourethra with tubed vaginal mucosal graft in phalloplasty female-to-male transsexual patients.
