The Gullwing Technique: A Novel Method of Transcorporal Artificial Urinary Sphincter Placement for the Fragile Urethra.

<bold>Objective: </bold>To describe the novel gullwing technique for artificial urinary sphincter (AUS) placement. The transcorporal technique for AUS placement is beneficial in patients with 'fragile urethras' (previous failed AUS, urethroplasty or history of radiation) however limitations include insufficient lateral and ventral urethral support in addition to potential cinching during corporotomy closure which, in the absence of additional grafting may restrict our ability to conserve internal corporal capacity and limit options for future preservation of erectile function via penile prosthesis placement. The gullwing variation of the technique offers the potential to circumvent these disadvantages.<bold>Materials and Methods: </bold>This case describes the gullwing variation of transcorporal AUS placement in a complex patient with a history of abdominopelvic trauma and prior failed AUS placements secondary to urethral erosion.<bold>Results and Conclusion: </bold>Transcorporal AUS placement in patients with prior urethral compromise has been shown to result in lower revision and erosion rates. The gullwing modification of the technique is a novel variation providing improved circumferential urethral protection and, with the addition of corporal grafting, aims to enable the preservation of the three-dimensional corporal volume necessary for ease of subsequent penile prosthesis implantation. However, studies assessing the long-term functional outcomes and durability of this technique are needed. [ABSTRACT FROM AUTHOR]
