척골측 전완부 감각유리 피판술을 이용한 요도협착의 치료

Abstract

In the treatment of urethral stricture, many problems still remain with the current methods making it a field of further exploration for reconstructive surgeon. Furthermore, when total or multiple strictures of the penile urethra exist, the methods of surgery become difficult due to a necessity for a long neourethra. Introduction of vascularized free flap has broadened the choice and improved the results of reconstruction for the urethra. The authors used a sensate ulnar forearm free flap in a patient with multiple penile urethral strictures for reconstruction. Uroflowmetry, 30 months after surgery, revealed that maximal flow rate was 15.5 ml/sec, average flow rate was 9.5 ml/sec, and voided volume was 157 ml. A urethrogram was performed 30 months postoperatively and a good result was achieved. The ulnar forearm free flap used by the authors are thin and pliable and is good for providing sufficient length to reconstruct the neourethra for a long urethral defect.
