Experience of Redo Urethroplasty for Complicated Recurrent Hypospadias / 대한비뇨기과학회지

ABSTRACT

PURPOSE: Patients requiring urethral reconstruction due to failed hypospadias repairs present a considerable technical challenge. Herein we report the experience of redo urethroplasties for complicated recurrent hypospadias. MATERIALS AND METHODS: From 1987 to 1997, we performed redo urethroplasty in 11 cases with complicated recurrent hypospadias. Types of recurrent hypospadias were coronal (1 case), distal shaft (4 cases), mid-shaft (1 case), and penoscrotal (5 cases) hypospadias. The interval between the last operation and redo operation was distributed from 8 months to 5 years. We analysed preoperative status, operative methods and their complications retrospectively. RESULTS: We performed urethroplasties using scrotal skin flap or buccal mucosal graft in only 2 cases. In spite of a paucity of usable penile skin, we performed urethroplasties with maximal use of remaining penile skin. Mathieu method was used in one case with coronal type. Mustarde operation was used in 4 cases with distal shaft hypospadias. And in 5 cases with penoscrotal type, we used Thiersch-Duplay method. Six of 11 patients had complications such as urethrocutaneous fistulas (4 cases) or recurrent hypospadias (2 cases) which were managed successfully later. CONCLUSIONS: Urethroplasty using penile skin maximally such as Mathieu, Mustarde, or Thiersch-Duplay methods appears to achieve success in patient with recurrent hypospadias subsequent to previous failed repairs.
