Artificial Urinary Sphincter in a High-Risk Urethra: Transcorporal Gullwing Modification Description of the Technique

BACKGROUND: In this report, we describe a modification of transcorporal artificial urinary sphincter place ment known as Gullwing modification. DESCRIPTION OF TECHNIQUE: Using a penoscrotal approach, bilateral corpora cavernosa flaps are harvested and sutured in the midline covering the lateral and ventral surfaces of the urethra. Transcorporal cuff placement provides dorsal reinforcement, thus having extra tissue buttressing all the circumference in cases of a fragile urethra due to previous urethral cuff erosion, urethroplasty, or pelvic radiotherapy. PATIENT AND METHODS: After previous urethral cuff erosion, radiotherapy, and urethral reconstruction, our patient complained of severe stress urinary incontinence. Due to the high risk of urethral complications, we proceed to a transcorporal artificial sphincter placement with urethral reinforcement through a bilateral cavernosal flap. RESULTS: The surgery was successfully completed, and after 6 weeks, sphincter was activated with satisfac tory results. Two years after surgery, his continence status is stable without complications. CONCLUSION: Urethral complications associated with artificial urinary sphincter surgery remain a challenge for the reconstructive surgeon. Reinforcement of the ventral aspect of the urethra through corpora cavernosal flaps may reduce the likelihood of urethral erosion in high-risk cases.
