Panurethral Strictures

Abstract

Panurethral strictures (PUS) are complex and long strictures that affect the entire anterior urethra. Such strictures are a challenge for the urethral surgeon and require the use of the entire surgical armamentarium. An accurate diagnosis is important to design a proper surgical plan. Surgical methods for reconstructing these long strictures are bilateral buccal mucosal grafts, “Q” penile skin flaps, McAninch flap (circular penile skin), Orandi flap (longitudinal penile skin), or a combination of such onlay flaps and grafts. For one-stage reconstructions, the graft is typically placed proximally to benefit from spongiosal blood supply, and the flap is placed on the distal bulb or penile urethra. In patients with inadequate skin, a combination of oral grafts may be used. In some PUS, one- or two-stages surgeries may be combined in the same patient. The absence of the urethral plate requires the creative combination of different tissue transfer techniques.KeywordsUrethral StrictureLichen SclerosusUrethral PlateCorpus SpongiosumPenile SkinThese keywords were added by machine and not by the authors.
