Changing practice in anterior urethroplasty

Abstract

Objective: To describe our experience of penile urethral repair and reconstruction, cataloguing the change in practice from one-stage flap to two-stage free graft procedures for anterior urethroplasty.

Patients and methods: Between January 1992 and December 1996, 79 patients underwent anterior urethroplasty. Of the 45 one-stage bulbar patch urethroplasties, 37 (76%) used buccal mucosal free grafts rather than flaps. Of the 34 penile urethroplasties, 26 (82%) (including all of the circumferential reconstructions) were two-stage procedures.

Results: Buccal mucosal free grafts were at least as good as local skin flaps for patch urethroplasty and two-stage repairs gave much better results than one-stage repairs for total circumferential reconstruction of the penile urethra.

Conclusions: For a patch urethroplasty of an uncomplicated stricture in the bulbar urethra, buccal mucosal free grafts are now the material of choice. For a patch urethroplasty of an uncomplicated stricture in the penile urethra the Orandi procedure remains the 'gold standard'. For a circumferential repair of the urethra, particularly the penile urethra, a two-stage repair using a free graft gives better results than a one-stage repair using a flap.
