Tubularized incision and prolonged plate urethroplasty in hypospadias

Abstract

Objective To summarize the experience of hypospadias repair with tubularized incision and prolonged plate urethroplasty. Methods From June 2015 to November 2015, a retrospective review of tubularized incision and prolonged plate urethroplasty was performed for 21 primary hypospadias patients. The clinical types were penile (n=17) and penoscrotal (n=4). After reserving urethral plate and degloving penile skin to penile root, full straightening out was performed. Incision of middle urethral plate was intended for broadening urethral plate. And sideway incision in the most obvious bent place of penis was made to prolong urethral plate. After indwelling catheter, urethra was formed. Results The average operative duration was 78(65-100) min. Postoperative complications included urethral fistula (n=3, 14.3%) and urethral stricture (n=4, 19.0%). All of them stayed in remission after 1-3 sessions of urethra dilatation. During a follow-up period of 3 months, 2 cases (9.5%) were complicated by urethral fistula. There was no instance of urethral stricture or recurrent penile curvature. Conclusions Tubularized incision and prolonged plate urethroplasty are effective for hypospadias. With a low incidence of postoperative complications, this procedure may be easily popularized at grass-roots. Key words: Urethroplasty; Hypospadias; Complication
