Complicated artificial urinary sphincter insertion using the transcorporal cuff: keys to the tunical flap technique

Area of Science:

• Urology
• Surgical Innovation
• Reconstructive Surgery

Background:

• Stress urinary incontinence (SUI) is a common complication after radical prostatectomy (RP).
• Artificial urinary sphincter (AUS) insertion is the standard treatment for refractory SUI.
• Previous interventions like urethroplasty, radiotherapy, or prior AUS failure can compromise urethral integrity, necessitating alternative surgical approaches.

Purpose of the Study:

• To demonstrate a modified transcorporal cuff (TC) placement technique for AUS implantation.
• To address challenges in patients with compromised urethral tissue due to prior interventions.
• To present the tunical flap (TF) modification for preventing AUS cuff erosion and improving outcomes.

Main Methods:

• A narrated video demonstrating the tunical flap (TF) modification for transcorporal AUS implantation.
• The procedure utilizes a perineal and penoscrotal approach.
• The TF technique involves using tunica albuginea from the corpora cavernosa for urethral support.

Main Results:

• The tunical flap technique provides circumferential reinforcement to the urethra.
• Early results show no postoperative hematoma formation.
• The technique aims to prevent cuff erosion in compromised urethral tissue.

Conclusions:

• The tunical flap modification for transcorporal AUS implantation is a safe and effective technique.
• It offers enhanced urethral support, preventing erosion in complex cases.
• This method preserves corporal volume and future candidacy for penile prosthesis implantation.
